Problems solved by technology

[0002] During the processing of flame-retardant plastics, an appropriate amount of industrial brominated flame retardants should be added to the plastic resin raw materials to be processed. Since the industrial brominated flame retardants contain a small amount of impurities such as unstable bromides and free osmanthus, these impurities decompose When the temperature is low, it is easy to decompose and produce HBr gas or free bromine during the thermal processing of plastics, which will turn the product yellow (in severe cases, it will turn orange or purple with an unpleasant smell), resulting in a decline in the mechanical properties of the product and damage to the product. Corrosion of processing equipment

Abstract

The invention relates to a brominated flame retardant yellowing inhibitor and an anti-yellowing brominated flame-retardant plastic product prepared from the yellowing inhibitor. The yellowing inhibitor is prepared by mixing modified compatible resin, a metallic oxide, higher fatty acid and other raw materials. When the anti-yellowing brominated flame-retardant plastic product is manufactured, the yellowing inhibitor and a plastic resin raw material are mixed by a kneader or a mixer so as to achieve the purpose of inhibiting the product from yellowing. The yellowing inhibitor provided by the invention has the advantages of scientific formula, low cost, convenience in preparation, easiness in implementation and application in a plastic processing technology and the like, and can effectively overcome the defect that a conventional brominated flame retardant changes the color of a plastic product after being added into the plastic product and thus affects the properties of the plastic product.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical preparations, and relates to a brominated flame retardant yellowing inhibitor capable of preventing yellowing of products due to the addition of brominated flame retardants during the processing of flame-retardant grade plastics. Background technique [0002] During the processing of flame-retardant plastics, an appropriate amount of industrial brominated flame retardants should be added to the plastic resin raw materials to be processed. Since the industrial brominated flame retardants contain a small amount of impurities such as unstable bromides and free osmanthus, these impurities decompose When the temperature is low, it is easy to decompose and produce HBr gas or free bromine during the thermal processing of plastics, which will turn the product yellow (in severe cases, it will turn orange or purple with an unpleasant smell), resulting in a decrease in the mechanical propertie...
