Abstract

An anti-aging PVC (polyvinyl chloride) plastic processing agent is prepared from the following raw materials in parts by weight: 8-20 parts of stannic oxide, 1.2-3.5 parts of metal stibium, 2-4 parts of towel gourd seed extract, 3-6 parts of aluminium oxide, 4-10 parts of ethylene-acrylic acid copolymer, 5-8 parts of silane coupling agent, 2-4 parts of thickener, 12-22 parts of methyl methacrylate, 1-2 parts of tri(propylene glycol) diacrylate, 2-5 parts of antioxidant, 3-6 parts of olefin, 4-7 parts of sorbitol, 1-3 parts of aloe skin dry powder, and 2-4 parts of inorganic salt. The anti-aging PVC plastic processing agent has the beneficial effects of improving aging resistance, improving surface lustrousness of a product, being simple in production process, and having better weather resistance.

Description

technical field [0001] The invention relates to an anti-aging PVC plastic processing aid. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with a wide range of uses. It has an irreplaceable position in the fields of chemical building materials, chemical anticorrosion and daily products. The ductility of PVC melt is poor, which can easily lead to melt breakage; PVC melt can relax slowly, which can easily lead to rough, dull and shark skin on the surface of the product. Therefore, it is often necessary to add processing aids during PVC processing to improve the above-mentioned defects of its melt. Processing aids are mainly a class of additives that can improve the processing performance of resins. There are three main modes of action: promoting resin melting, melt rheological modification and imparting lubricating functions. The additives play a very important role in the processing process. effect. However, the anti-aging effect of addit...
