Composite flame retardant

Abstract

The invention discloses a composite flame retardant which is used as a flame retardant product and can be directly used as an additive to be added into ingredients of a product with a flame retardant requirement. The composite flame retardant comprises the following components in parts by weight: 5-30 parts of polydimethylsiloxane, 5-30 parts of silicate ester resin, 2-12 parts of stearate, 10-40 parts of zinc borate, 5-20 parts of calcium carbonate, 20-40 parts of aluminum hydroxide, 20-40 parts of magnesium hydroxide, 5-15 parts of talcum powder and 10-20 parts of sodium silicate. The composite flame retardant is easy to obtain raw materials, simple in preparation process, excellent in flame retardance, free of poisonous gas, good in smoke suppression, low in consumption and capable of meeting the general flame retardant requirement and also improving the mechanical property and compatibility of a substrate to a certain extent.

Description

technical field [0001] The invention relates to the technical field of flame retardant products, in particular to a composite flame retardant. 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 envi...

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
