Silicone powder special for engineering plastic

Abstract

The invention discloses silicone powder special for an engineering plastic. The silicone powder consists of the following components in percentage by weight: 75-85% of alkyl silicone oil, 10-15% of fumed silica, 3-5% of magnesium carbonate, and the balance of calcium chloride. The silicone powder is specially used in a production process of an engineering plastic, and the production process of the engineering plastic, after silicone master batches disclosed by the invention are added, has the following advantages: the molecular structure power among engineering plastic molecules is enhanced, the mechanical property of the engineering plastic is improved, the fluidity of the engineering plastic is increased, and especially for a flame-retardant engineering plastic, the fluidity between a flame retardant and other raw materials is improved to ensure that the flame retardant can play a stronger flame-retardant effect and cannot deteriorate due to overheating in a screw for a long time. The silicone powder can regulate the pH value of the engineering plastic and enable the pH value to be neutral, and is nontoxic and harmless.

Description

technical field [0001] The invention relates to the technical field of silicone powder, in particular to a special silicone powder for engineering plastics. Background technique [0002] Silicone powder is a high-efficiency lubricant for ultra-high molecular weight plastics that does not contain organic carriers. It can be integrated with almost all types of thermoplastics and is widely used in the production process of various thermoplastics. It can improve plastic processing fluidity and mold release performance, and reduce torque. , reduce equipment wear, easy mold filling, reduce product defect rate, significantly reduce friction coefficient, improve smooth performance, improve surface gloss, enhance surface silky touch, improve wear resistance and scratch resistance. It is a general plastic lubricant such as It is an upgraded product of EBS and silicone masterbatch plastic lubricant, which overcomes the weakness of traditional silicone oil as a plastic lubricant that is...

AI Technical Summary

Problems solved by technology

However, the silicone powder of the prior art also has certain defects, especially in the application process of the production process of engineering plastics, its molecular structural strength is not high, so that the mechanical properties of engineering plastics are low, and the flame retardant cannot be fully utilized. flame retardant performance, so it is necessary to improve
