Problems solved by technology

PVC pipes have the advantages of acid resistance, alkali resistance, corrosion resistance, and high strength. However, the impact resistance of PVC pipes produced by major manufacturers is not good, especially in the plasticization process in the processing of PVC products. The dispersion and processing fluidity of PVC melt have always been a difficult problem

Embodiment

[0029] The preparation method of high-impact PVC / ACS pipe comprises the following steps:

[0030] The first step: preparation of material A

[0031] Get the following raw materials in parts by weight: polyvinyl chloride SG-5 60, polyvinyl chloride recycled material 40, active calcium 25, chlorinated polyethylene 15, ABS high rubber powder 6, isooctyl dimercaptoacetate di-n-octyl tin 5, even Nitrogen dicarboxamide 0.4, ACM 10, isopropyl tris(dioctyl pyrophosphate acyloxy) titanate 0.5, antioxidant 1010 0.6, ethylene bis stearamide 0.5, didodecyl alcohol ester 0.2, Modified nano powder 10,

[0032] Among them, the modified nano-powder is prepared by the following method: after mixing olivine powder, dolomite powder, and talc powder in equal proportions, burning at 700°C for 5 hours, then grinding into nano-powder, mixing 5% of the weight of the powder Bis(dioctyloxypyrophosphate) ethylene titanate was stirred evenly, dried, and pulverized into powder,

[0033] Put the weighe...

Abstract

The invention discloses a high-impact PVC (polyvinyl chloride) / ACS (acrylonitrile-chlorinated polyethylene-styrene terpolymer) tubing and a preparation method thereof. The tubing is prepared from a material A and a material B by steps of proportionally mixing, extruding and granulating. Since a formula is optimized further, dispersing of organic packing can be improved during processing of the PVC tubing, fluidity of PVC melt can be improved, tensile strength and elongation at break can be improved, and the defect of good ductility but low hardness of polyethylene products produced by the aid of chlorinated polyethylene is overcome. In addition, since components such as ACM (poly(acrylic acid ester rubber)), MBS (methacrylate butadiene styrene) and ACS resin are utilized in the formula, cold bending performance and impact resistance of the tubing produced according to the formula are improved.

Description

technical field [0001] The invention relates to the field of PVC pipe production, in particular to a high-impact PVC / ACS pipe and a preparation method thereof. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, and plasticizers, anti-aging agents and other auxiliary materials are added to increase its heat resistance, toughness, ductility, etc. PVC is a well-loved, popular and widely used synthetic material in the world today. PVC pipe is a mature pipe, mainly used in water supply and drainage projects. PVC pipes have the advantages of acid resistance, alkali resistance, corrosion resistance, and high strength. However, the impact resistance of PVC pipes produced by major manufacturers is not good, especially in the plasticization process in the processing of PVC products. The dispersion and processing fluidity of PVC melt have always been a difficult problem. Contents of the invention [0003] The object of the present invention is ...
