Anticorrosion stable anti-aging plastic plate

Abstract

The invention discloses an anticorrosion stable anti-aging plastic plate. The anticorrosion stable anti-aging plastic plate is prepared from the following raw materials in parts by weight: 0.7-1 part of calcium stearate, 2-3 parts of octyl isothiazolinone, 2-3 parts of sucrose acetate isobutyrate, 0.7-1 part of glycereth-n cocoate, 1-2 parts of trithiocyanuric acid, 110-160 parts of polyvinyl chloride, 1-2 parts of triphenylphosphine, 10-13 parts of polyisoprene, 27-30 parts of dimethyl nylon acid, 0.5-1 part of fulvic acid, 0.1-0.2 part of zinc pyrithione, 4-6 parts of dimethyl fumarate, 10-14 parts of sea-foam stone powder, 0.5-1 part of potassium citrate, 0.6-1 part of diisopropyl ethanol amine, 3-4 parts of rosin alcohol, 0.1-0.5 part of aluminum potassium sulfate and 0.1-0.3 part of a silane coupling agent KH560. The anticorrosion stable anti-aging plastic plate disclosed by the invention has the advantages that anticorrosion capability of the plate finished product can be effectively improved as octyl isothiazolinone, dimethyl fumarate and the like are added, the added triphenylphosphine and the like can improve antibacterial property, the added zinc pyrithione, calcium stearate and the like can improve stability of the plate finished product, the raw materials are reasonably treated, and the anticorrosion stable anti-aging plastic plate has high anticorrosion capability and antibacterial property and superior overall performance.

Description

technical field [0001] The invention relates to the technical field of plastic plates, in particular to an anti-corrosion, stable and aging-resistant plastic plate. 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 increase of tempe...

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
