Problems solved by technology

[0003] Soft PVC is used in wire and cable, waterproof membranes of different thicknesses, folding doors, calendered films, textile products, artificial leather, floor leather, hoses, gloves, children's toys and some sealants and coatings, etc., industrialized Soft polyvinyl chloride products often use small molecule plasticizers, the addition amount is as high as 30%-50%, such as dioctyl phthalate, bis(2-ethylhexyl) phthalate, etc. The effect is unstable, and problems such as dissolution, volatilization, and migration will occur during processing and long-term use, which will not only deteriorate the performance of the product, lose its use value, but also cause pollution to the environment

Abstract

The invention provides environment-friendly soft polyvinyl chloride granules. The environment-friendly soft polyvinyl chloride granules are prepared from the following raw materials: 100 parts of polyvinyl chloride resin, 30-130 parts of ester plasticizer, 5-10 parts of epoxidized soybean oil, 0.1-2 parts of calcium / zinc compound stabilizer, 0.1-1 part of lubricating agent and 0.01-0.5 part of halloysite nanotube. The soft polyvinyl chloride granules have high plasticizing efficiency, superior toughness, extremely low precipitation rate, and safety protection of the environment and body health are facilitated.

Description

technical field [0001] The invention relates to a polyvinyl chloride pellet composition, in particular to an environment-friendly soft polyvinyl chloride pellet. Background technique [0002] Polyvinyl chloride (PVC) is the second largest general-purpose plastic in the world. Its usage is second only to polyethylene (PE). Its strength and modulus are the first in general-purpose plastics. It has excellent mechanical properties, chemical corrosion resistance, and good flame retardancy. advantage. Polyvinyl chloride resin is PVC resin, which has excellent physical and chemical properties, strong corrosion resistance, and stable chemical properties. Except for a few solvents at room temperature, PVC resin can withstand any concentration of hydrochloric acid, sulfuric acid below 90%, 50-60% of nitric acid and less than 20% of caustic soda; excellent flame retardancy and electrical insulation, pure PVC resin oxygen index as high as 60%, is a flame retardant material, although ...
