Stable polyvinyl chloride material with durability and preparation method thereof

Abstract

The invention relates to a stable polyvinyl chloride material with durability and a preparation method thereof. The stable polyvinyl chloride material with durability is composed of the following raw materials, in parts by mass: 10-15 parts of diatomite, 0.3-1 part of ammonium ethoxylated alkyl sulfate, 0.7-1 part of N-methylol acrylamide, 0.1-0.3 part of bisphenol A diglycidyl ether, 0.7-1 part of phytic acid, 1-2 parts of zinc diricinoleate, 0.5-1 part of polyacrylamide, 0.1-0.2 part of p-nitrophenol, 6-10 parts of hydroxyethyl acrylate, 1-1.2 parts of dicumyl peroxide, 100-120 parts of polyvinyl chloride, 1-2 parts of dodecyl trimethyl ammonium chloride, 2-3 parts of aluminium isopropoxide, 0.3-1 part of chitosan, 0.1-0.2 part of calcium naphthenate, 4-6 parts of dibutyl maleate, 0.3-0.5 part of a silane coupling agent KH560, 0.3-1 part of pentaerythritol tetrakis[beta-(3,5-di-tert-butyl-4- hydroxyphenyl)propionate], and 1-2 parts of calcium palmitate. The polyvinyl chloride material provided in the invention has good heat resistance and lengthened product service life, and is a novel environmentally-friendly and durable industry material.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride materials, in particular to a stable and durable polyvinyl chloride material and a preparation method thereof. Background technique [0002] Pure polyvinyl chloride resin has poor heat resistance and stability. When it is heated and stabilized to 90°C, a slight thermal decomposition reaction will occur. As a widely used plastic material, polyvinyl chloride is required to have certain stability, flame retardancy and heat resistance in many applications. In addition, for PVC products that are exposed to the outdoors all year round, such as outdoor drainage pipes, traffic protection fences, and plastic doors and windows, etc., which are subjected to the test of wind and sun, how to improve the sunscreen and anti-ultraviolet properties of such PVC products to prolong Its service life has become one of the key research objects of polyvinyl chloride materials today.
