Problems solved by technology

MBS is mainly used in transparent plastic profile products. It is best not to share EVA with lead stabilizers. When they are used together, the molding processability is poor and easy to cause powder spots. It is best not to share CPE with zinc stabilizers, and the low temperature performance of CPE is not good. great

Abstract

The invention discloses a multi-component plastic section bar and its preparation method. The preparation method provided by the invention comprises steps of successively carrying out a batch mixing reaction and heating moulding treatment on raw materials of a PVC resin, a Ca / Zn composite stabilizer, chlorinated polyethylene, calcium carbonate, an acrylic acid ester impact modifier ACR, titanium dioxide, eleaostearic acid, a polyethylene wax, an ultraviolet ray absorber and a pigment according to a certain amount by weight so as to obtain a finished product. The preparation method is simple and the formula is reasonable. The multi-component plastic section bar prepared in the invention has good heat radiation performance and good stretching performance, and can be effectively applied in every field.

Description

technical field [0001] The invention relates to a profile, in particular to a multi-component plastic profile and a preparation method thereof. Background technique [0002] Due to the huge market demand and broad development prospects, plastic profiles have developed rapidly in my country in recent years. Due to the fierce market competition, all plastic robot Manufacturers all consider a question, how to improve the productivity and pass rate of plastic profile products on the premise of ensuring product quality, and how to maximize the capacity of the equipment to reduce the production cost of the product. [0003] Plastic profile products are widely used: window frames, stair handrails, wiring troughs, skirting boards, special-shaped pipes, etc. The raw materials are mainly hard PVC, and a few are semi-rigid PVC, soft PVC, polyurethane low foaming and other materials. [0004] For hard PVC plastic profiles, there is a disadvantage of poor impact resistance, which is of...
