Abstract

The invention relates to a high-elasticity environment-friendly polyvinyl chloride material composition as well as a preparation method and application of the composition. The composition contains the following raw material components in parts by weight: 100 parts of polyvinyl chloride resin, 0.5-15 parts of a stabilizer, 0.5-20 parts of a processing aid, 1-20 parts of a mass modifier, 0.1-10 parts of a lubricant, 0.5-20 parts of a filler and 0-5 parts of a pigment, wherein the K value of the polyvinyl chloride resin is 60-65; the stabilizer is at least one of a zinc-calcium stabilizer and a magnesium-aluminum-zinc stabilizer. According to the high-elasticity environment-friendly polyvinyl chloride material composition, a tin-containing stabilizer or a lead-containing stabilizer is not used, and meanwhile, the high-elasticity environment-friendly polyvinyl chloride material composition has excellent elasticity and strength performance and is good in color and luster and low in cost.

Description

technical field

[0001] The invention relates to the technical field of new materials, in particular to a high-elasticity environment-friendly polyvinyl chloride material composition and a preparation method and application thereof. Background technique

[0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics, divided into soft and hard PVC, among which rigid PVC has been widely used in building materials, packaging materials, Christmas trees and other fields. European and American countries are used to adding Christmas trees to their families every Christmas to increase the festive atmosphere. The growth rate of natural trees is slow, and the price increases sharply every year, which cannot meet the market demand. The Christmas tree is made of PVC hard material, and its color, gloss and elastic recovery are similar to natural trees, and it is realistic and practical.

[0003] According to market demand analysis, the market demand for PVC hard glue mate...
