Abstract

The invention discloses a flame retardant material and a preparation method thereof, and relates to the technical field of a flame retardant material. The flame retardant material is prepared from thefollowing raw materials in parts by weight: 50 to 60 parts of epoxy resin, 12 to 20 parts of carbomer resin, 30 to 40 parts of modified magnesium hydroxide, 8 to 14 parts of emulsifiers, 10 to 18 parts of mullite, 10 to 16 parts of hydrotalcite, 6 to 8 parts of dispersing agents, 4 to 10 parts of trimethylolpropane, 4 to 8 parts of calcium carbonate whiskers and 1 to 3 parts of curing agents. Theflame retardant material has excellent fireproof performance and mechanical strength; the dispersing performance of fillers in the material is good.

Description

technical field [0001] The invention belongs to the technical field of flame retardant materials, and in particular relates to a flame retardant material and a preparation method thereof. Background technique [0002] Plastics based on polymers have greatly facilitated people's lives, but most of the synthetic materials are combustible or inflammable, which will produce thick smoke or toxic gases when burned, and pollute the environment. Magnesium hydroxide Because of its wide source of raw materials, good flame retardant performance, and non-toxic corrosion performance, it is considered to be an environmentally friendly flame retardant with great development potential. It is widely filled in polymers, but the surface of magnesium hydroxide crystals has positive The charge, the affinity with lipophilic polymer molecules is not good, the crystal grains tend to secondary aggregation, and at the same time, pores will be generated in the interface between magnesium hydroxide and...
