Problems solved by technology

[0003] With the rapid development of the economy, PVC plastics occupy an important position in many fields because of their non-flammability, high strength, weather resistance and excellent geometric stability. The transparent auxiliary materials used in PVC plastics in the market There are fewer types of additives. Although it has improved the performance of PVC plastics, the effect is obvious, but the use of transparent additives for PVC plastics in production is relatively large, and the cost is high. Therefore, it is necessary to improve its production cost and reduce transparency. Proportion of additives in PVC plastic production

Abstract

The invention discloses a transparent additive for polyvinyl chloride (PVC) plastics. The transparent additive is characterized by being prepared from the following components in parts by weight: 15-25 parts of polyethylene wax, 23-41 parts of fatty acid, 13-19 parts of stabilizer, 5-9 parts of reactant, 0.1-0.3 part of hydrogen peroxide, 12-33 parts of additive, 8-45 parts of ethylene oxide and 0.1-0.3 part of anti-aging agent. Compared with the prior art, the transparent additive for the PVC plastics has the advantages that due to use of the polyethylene wax in the transparent additive for the PVC plastics, the transparent additive for the PVC plastics can improve the cold resistance, heat resistance, chemical resistance and abrasion resistance of the PVC plastics; hydrogen peroxide guarantees the supply of oxygen molecules in a reaction process; ethylene oxide guarantees the chemical formation of the additives; the stabilizer, the additives and the anti-aging agent effectively improve the overall performance; the transparency is improved while the using amount of the transparent additive is reduced. The preparation process is simpler, the labor cost and the raw material cost arereduced, and the product is convenient and fast to use.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to a transparent additive for PVC plastics. Background technique [0002] PVC plastic refers to the compound polyvinyl chloride in the chemical industry. The English abbreviation is PVC. This is the most widely used meaning of PVC. Its natural color is light yellow and translucent, shiny, and its transparency is better than polyethylene and polypropylene, and worse than polystyrene. According to 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, but lower than that of polypropylene. Whitening will appear at the inflection point. Common products: plates, pipes, shoe 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. [0003] With th...
