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

Abstract

The invention discloses a heat-resistant stable plastic plate. The heat-resistant stable plastic plate is prepared from, by weight, 1-2 parts of calcium propionate, 2-4 parts of polyformaldehyde, 2-3 parts of stabilizing auxiliary, 1-2 parts of sodium carboxymethylcellulose, 2-3 parts of diethylene glycol dibenzoate, 0.1-0.2 part of titanate coupling agent 201, 4-6 parts of dimethyl isophthalate, 100-130 parts of polyvinyl chloride, 0.7-2 parts of diglycolamide oleate, 0.6-2 parts of 2-mercapto benzimidazole, 0.6-1 part of ricinoleic acid, 0.6-1 part of potassium dichromate, 30-40 parts of 96-98% sulfuric acid, 3-5 parts of sisal fiber, 2-3 parts of conch shell powder, 0.4-2 parts of diacetone acrylamide and 10-14 parts of expansible graphite. Various stabilizing auxiliaries are added, the heat-resistant stability of the finished plate can be effectively improved, and the service life of the plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic plates, in particular to a heat-resistant and stable 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 the in...
