Abstract
The invention discloses a resin-based crystal whisker composite material, which is prepared from the following raw materials in parts by weight: 2 to 3 parts of beewax, 4 to 7 parts of aluminum isopropoxide, 1 to 2 parts of zinc diricinoleate, 0.8 to 1 part of sodium alkyl benzene sulfonate, 100 to 130 parts of polypropylene, 24 to 30 parts of 3-(trifluoromethyl) benzophenone, 7 to 9 parts of hydroquinone, 10 to 13 parts of calcium carbonate whisker, 0.4 to 1 part of potassium carbonate, 0.2 to 0.5 part of sodium carbonate, 100 to 120 parts of sulfolane, 0.3 to 1 part of 2-mercapto benzimidazole, 1 to 3 parts of butyl benzyl phthalate, 4 to 6 parts of alkyd resin, 0.8 to 2 parts of polyacrylamide, and 0.1 to 0.2 part of ethylene glycol phenyl ether. A filler can be more favorably dispersed uniformly in a base body, crystal whiskers are prevented from gathering, accumulating and caking, a rheological property of the composite material is improved helpfully, and a mechanical property of a finished product material is improved.
Description
technical field [0001] The invention relates to the technical field of composite materials, in particular to a resin-based 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 the...
