Holy masterbatch invented a transparent filling masterbatch. It is composed transparent additive 75%-85%, resin 10%-20%, processing aid 3%-6%, surface treatment agent 1%-2%; transparent additive is a composite powder of two non-metallic minerals with an average particle diameter of 2-5 microns; processing aids are low molecular weight polyethylene wax and stearic acid and their salts, weight percentage 3%-6% of the processing aids include 3%-5% of low molecular weight polyethylene wax, and stearic acid and its salt are 1%-2%. The invention is close to the transparent effect of the resin color, has small stacking volume, low cost, large output and good promotion value.
The transparent filler masterbatch has the advantages of low price, high rigidity, hardness and molding stability of the product, and has little influence on the transparency of the plastic, and has wide applications. At present, the transparent filler masterbatch which is commonly used on the market mainly uses the barium sulfate masterbatch produced by modifying the ultrafine precipitated barium sulfate, the talc masterbatch produced by the fine talcum powder, and the sodium sulfate masterbatch produced by the elemental powder. The advantage of the barium sulfate masterbatch is that the product has good whiteness and gloss, bright colors, and improved heat distortion of the product. The disadvantage is that the transparency is not ideal, the product is white, the ratio is big, and the price is high. The advantage of the talc masterbatch is that the transparency of the product is good, but the processing cost of the masterbatch is large, it is difficult to disperse, and the price is not cheap. The advantage of sodium sulfate masterbatch is that the price is relatively cheap, but the transparency is not ideal. The product is white, salty and easy to precipitate.
