Problems solved by technology

[0003] At present, domestic and foreign research on halogen-free flame retardant mainly focuses on red phosphorus series, inorganic hydroxide series and montmorillonite minerals, but the effects are not ideal, and there are the following reasons: when the amount of flame retardant added is relatively high hours, the flame retardant effect is not obvious, and it cannot meet the national building material standards; when the flame retardant is added in a large amount, although the flame retardant problem is solved, it seriously affects the performance of the material

Abstract

The invention relates to an organic silicon-based composite flame retardant, which is used for flame retardant products and capable of directly serving as an additive to be added into product ingredients required to be flame retarded. The organic silicon-based composite flame retardant is characterized in that the flame retardant is prepared by compounding of the following effective components of 5-20 parts by weight of polydimethylsiloxane, 10-30 parts by weight of silicate ester resins, 1-10 parts by weight of stearate, 10-35 parts by weight of zinc borate, 10-20 parts by weight of calcium carbonate and 30-75 parts by weight of aluminum hydroxide. According to the organic silicon-based composite flame retardant, the flame retardant performance is good, the toxic gas can not be generated, the smoke suppression performance is good, the general flame retardant requirements can be met only by small quantity of the flame retardant, and further the mechanical performances of base materials and the compatibility with the base materials can be improved to some extent.

Description

technical field [0001] The invention relates to a flame retardant, in particular to an organosilicon composite flame retardant of polymer material. Background technique [0002] With the development of the polymer material industry, plastics are more and more widely used in various fields of production and life. At the same time, fires caused by the flammability of plastics have also caused heavy casualties and huge losses In order to reduce the economic loss, some industrial developed countries began to produce and apply flame-retardant plastics. With the development of electrical appliances, electronics, machinery, automobiles, ships, aviation and aerospace, the requirements for flame retardant of product materials are getting higher and higher, which leads to the rapid development of research, production and promotion of flame retardants and flame retardant materials. Due to the expansion of the application field of flame retardant materials and the needs of human living...
