How to masterbatch

September 30, 2008 on 10:37 pm | In Tech | No Comments

Masterbatch by the excess chemical additives, dispersants and carriers are resin composition. Masterbatch is the extraordinary amount of paint (dye) attached to the resin contained in uniform and be in the aggregate.
Constitute a major masterbatch

1, Color
General points of organic pigments such as phthalocyanine green, and so on; inorganic pigments such as red iron oxide, titanium dioxide; dyes such as pink to restore the scattered orange and so on. Polyolefins, PVC masterbatch is used in paints, dyes generally can not be said for coloring polyolefins, or give rise to migration seriously.

2, Dispersant
The main color on the surface wetting, the paint will help further spread and stability in the resin, at the same time must be compatible with the resin, color does not affect product quality. Polyolefin masterbatch dispersant generally low-molecular-weight polyethylene wax esters or hardware, such as zinc. Engineering Plastics masterbatch dispersant generally have polar low-molecular-weight polyethylene wax, hard-acid magnesium, calcium, and other hard-ester.

3, The carrier resin
So that the color masterbatch were uniformly distributed and granular. Choice of carriers to be considered with the color of the resin compatibility, but also to consider masterbatch should have a good dispersion, the carrier mobility should be greater than the colored resin, at the same time after being colored does not affect the quality of products. If a larger selection of melt index of its kind polymer, so that the masterbatch melt index was higher in the polymer to ensure that the final products of the same color. PE, PP masterbatch choice LDPE (low density polyethylene) resin as the carrier, PS, ABS masterbatch modified PS choice as the carrier.

Calcium carbonate masterbatch filled with PP carrier

September 30, 2008 on 10:09 pm | In Products | 2 Comments

Calcium carbonate filler material from the mother of the last century since the birth of the early 1980s, for plastic processing industry and society as a whole has made great contributions to the annual output reached more than 1,000,000 tons, is a modified plastic one of the important species.

Masterbatch fill the first carrier to use the polymer when the PP is a by-product – random polypropylene (APP), hence known as APP masterbatch. After the Beijing Yanshan Petrochemical Corporation as a result of technological transformation, no depletion of the source of polypropylene, synthetic resin and calcium carbonate as a substitute during the shortage, the market demand. In this context, in order to polyethylene resin as the carrier of calcium carbonate-filled masterbatch came into being, such as LDPE1F7B is still the mother is expected to fill most of the major raw materials.

As the mother of filling materials are mainly used for stretching the use of polypropylene bags and packing tape, from the price, compatibility and strength in areas such as stretching, the use of polypropylene resin as the carrier filled more suitable for such a masterbatch.

The early 1990s, the then Ministry of Light Industry Institute of Plastics Processing application to be the first to introduce polypropylene powder as the carrier resin material calcium carbonate-filled mother, known as the PPM masterbatch, and in 1992 won the State New product class title.

PPM masterbatch small body PP powder as a carrier compared to price, such as PE resin 1F7B a significant advantage, so far has kept 1,000 yuan / ton over the price difference. At the same time, the low density of the PP in itself means that the same quality of the resin more of the number of vector borne polymer resin.

In addition the strength of PP is higher than PE, under the same conditions allow stretching, packaged with a higher intensity, such as different carrier made of resin-filled PP masterbatch for injection molding products, and will be stretching, packaged with Similar products such as the results of the PP as the carrier is about to fill the resin masterbatch with other resins for the carrier to fill the masterbatch, according to the QB 1126-91 “filled polyolefin masterbatch” industry standard spline made of injection, When the same formula, sample preparation equipment, conditions at the same time, PP as the carrier filled the masterbatch best.

The PP as the carrier filled with calcium carbonate masterbatch production of the main points are as follows:
① PP granular powder PP than cheaper, more evenly mixed with calcium carbonate, priority should be to use.
② powder melt flow rate of the PP not be too big, 4 ~ 10g/10min for good.
③ PP powder did not join the antioxidant, lubricant additives, and so on, we must add the appropriate amount.
④ PP powder stored in the process of gradual degradation, let sour, it must be time to ask the production and use in a timely manner, preferably in a polymer used up within one month after.
⑤ to PP powder as the carrier of calcium carbonate-filled masterbatch can use the same parallel to the twin-screw extruder processing, the ratio of calcium carbonate can reach more than 80%. The key question is not eager Granulation air-cooled surface model, we should not be using the pull water granulation, the only way to use air-cooled grain belt.
1.2.2 for ABS in place of the main goals of the modified Polypropylene

(1) Co., Ltd. of Japan Karp CALP resin composition, performance and purpose
CALP resin on many occasions can be expensive to replace the ABS, there are still obvious shortcomings.

  1. Than the density of large ABS;
  2. Low surface hardness, described intolerance;
  3. Less rigid;
  4. Low-gloss surface;
  5. Poor surface coating;
  6. Forming large size shrinkage. The original use of ABS injection molding die need to be modified to use modified PP resin.

PVC color masterbatch formula

September 20, 2008 on 8:08 pm | In Tech | 3 Comments

(1)Carrier

Carrier resin carrying pigment, is a material which even disperse the pigment with the action of dispersant and processing modifer. Some  PVC color masterbatch imported is adopted special polyester as carrier. Normally it is also used PVC as carrier by choosing suspersion method with good fluidity.

(2)Plasticiser

Molecules among polar PVC is great attraction, high viscosity, difficult melt and fluid, so it need to add plasticiser to reduce the action of molecules for resin, then to reduce the melt temperature and viscosity of PVC resin. In view of the hard and soft of masterbatch , it can add a kind or several compands  plasticiser as per requirement.  Normally DOP with good commonality is used as main
plasticiser, and epoxy compands with good volatility and stability as auxiliary plasticiser.

(3)Heat stabilizer

PVC is easy to break down with heat to release HCL gas, so it needs to add stabilizer. As color masterbatch is produced by twice-screw extruder, so it requests higher harsh for the heat stability of resin series.

(4)Working modifying agent

As color masterbatch, ideal fluidity should exceed natural pigment, namely masterbatch viscosity is lower than the natural pigment, so that it has even coloring. Adding high density pigment will largely increase the voscosity of PVC. Specially, when adding carbon with difficult dispersion and high oil adsorption, the series voscosity is still very high, since adding very high compands plasticiser. It will reduce effectively series melt viscosity by choosing suitable processing modifer, so it wil benefit for dispersion of pigment to ensure the stability of continue processing.

(5)Lubricant

In PVC resin, it needs to add inner and external lubricant and should keep balance in inner to reduce the highest torque of resin melting.and ensure the brightness of product apperance.

(6)Paint

PVC coloring  is nomally adopted inorganic and organic pigment. As PVC will break down to release HCL gas when it is in high heat, it will make some low acid-resistance colorant to change color, so the pigment used in PVC should meet as follows:
a、temperature tolerance,requesting pigment process not to be decomposed between 160~220℃ ;
b、be unacted on By HCl;
c、good  migration-resistance
d、resistance to elements good;
e、cheap and good。

If discrepancy exists between the English texts and the Chinese texts, the Chinese texts apply.
