Abstract

The invention discloses a flame-retardant whisker composite material, consisting of the following raw materials in parts by weight: 100-130 parts of polypropylene, 24-30 parts of 3-(trifluoromethyl) benzophenone, 7-9 parts of p-benzenediol, 10-13 parts of calcium carbonate whiskers, 0.4-1 part of potassium carbonate, 0.2-0.5 part of sodium carbonate, 100-120 parts of sulfolane, 2-3 parts of ammonium polyphosphate, 6-7 parts of zirconium oxychloride, 1-2 parts of sodium myrastate, 0.3-1 part of butyl tin mercaptide, 0.5-1 part of beta-hydroxyl alkyl amide, 8-10 parts of wollastonite powder, 0.5-1 part of dodecyl dimethyl betaine, and 0.2-1 part of tert-butyl p-diphenol. The ammonium polyphosphate and the like are added into the flame-retardant whisker composite material disclosed by the invention, so that the flame retardance of a finished product can be effectively improved, and the safety and fireproofing property of the finished product are can be improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a flame-retardant whisker composite material and a preparation method thereof. Background technique [0002] Research on composite materials is a very active scientific research field in recent years, and is expected to have a profound impact on society in the future. Among the numerous research directions of composite materials, it is always of great significance to introduce inorganic fillers into polymers to obtain significant performance improvements. These composite materials have greatly enhanced the polymer matrix in terms of mechanical properties, electrical properties and thermal properties, and can be widely used in marine, automotive, aerospace and other fields that require high mechanical properties and heat resistance. The more important point about this type of composite material is that the reinforcement only needs a small amount of addition to improve...
