Problems solved by technology

[0003] In recent years, as computers have become daily necessities, computers are composed of various components, and the basic materials of most components are plastic products; with the aggravation of school teaching tasks and changes in teaching and learning methods, computers are used in schools. The use of the computer becomes more and more frequent, which will greatly increase the probability of computer fires. Based on the existence of the above problems: after years of research and development, the inventor has developed a six- Alternatives to bromocyclododecane, brominated butylbenzene polymer flame retardant

Abstract

The invention provides a method for preparing a composite polystyrene material for a computer. The composite polystyrene material is characterized by comprising the following raw materials in parts by weight: flame-retardant functional additives, dimethylformamide, citrate, artificial stone transparent powder, dibutyl phthalate, modified soybean protein, polystyrene, dimethyldichlorosilance, diphenyl dichlorosilane, nano-crystalline cellulose powder and modified mineral powder. According to the invention, each material is high in fluidity, uniformity and technological adaptability in the process of preparing the composite polystyrene material for the computer, and the prepared composite polystyrene material is high in stability; and moreover, the composite polystyrene material have good flame-retardant property in the process of preparing the composite polystyrene material for the computer.

Description

technical field [0001] The invention relates to a preparation method of polystyrene composite material for computer. Background technique [0002] In March 2001, the United Nations Environment Program signed the epoch-making international convention on persistent organic pollutants "Stockholm Convention" in Stockholm; this convention is a milestone for human beings to protect the environment. In the Convention, three categories of twelve compounds are included in the scope of control, which means that the production and use of these compounds are banned globally, including the brominated flame retardant hexabromocyclododecane. Hexabromocyclododecane has good stability to heat and ultraviolet light, low dosage and good flame retardant effect, but it is also a persistent pollutant with migration and accumulation properties, which can lead to a decrease in serum thyroid hormone concentration, Inhibiting the normal absorption of neurotransmitters, causing pathological changes i...
