Impact-resistant and high-strength plastic plate and preparation method thereof

Abstract

The invention discloses an impact-resistant and high-strength plastic plate. The impact-resistant and high-strength plastic plate comprises raw materials in parts by weight as follows: 0.2-0.4 parts of hexabromocyclododecane, 4-6 parts of polyisoprene, 100-140 parts of polyvinyl chloride, 0.6-1 part of lauroyl diethanolamide, 0.7-1 part of p-toluenesulfonic acid, 10-14 parts of polyethylene fibers, 0.7-1 part of potassium dichromate, 50-60 parts of 96%-98% sulfuric acid, 0.4-1 part of caprylic capric triglyceride, 5-7 parts of tributyl citrate, 2-3 parts of zinc dihydrogen phosphate, 10-14 parts of clay, 0.6-1 part of dialkyl p-diphenol, 2-3 parts of calcium fluoride, 0.2-0.3 parts of N,N-diethyl aniline, 1-2 parts of aluminum tripolyphosphate, 3-5 parts of polyvinyl alcohol and 2-3 parts of fine silica aerogel. Polyisoprene, fine silica aerogel and the like are added, so that the impact-resistance strength of a finished plate is effectively improved.

Description

technical field [0001] The invention relates to the technical field of plastic plates, in particular to an impact-resistant high-strength plastic plate and a preparation method thereof. Background technique [0002] The natural color of polyvinyl chloride (PVC) is light yellow translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. PVC has high hardness and mechanical properties. And it increases with the increase of molecular weight, but decreases with ...

AI Technical Summary

Problems solved by technology

The elasticity of soft PVC is 1.5-15MPa, but the elongation at break is as high as 200%-450%. It can be used in chemical industry, electroplating, lining of electrolyzer, insulating cushion, train, automobile interior and auxiliary materials, etc. The heat resistance stability of PVC is very poor. It begins to decompose at 140°C, and the melting temperature is 160°C. The linear expansion coefficient of PVC is small, and it is flame retardant. Poor resistance, poor heat and humidity resistance and other shortcomings, seriously affecting the service life of the plate
