Abstract

The invention discloses a hydrophobic high-elasticity composite material. The hydrophobic high-elasticity composite material is prepared from, by weight, 0.6-1 part of stannous sulfide, 1-2 parts of polybenzimidazole, 0.3-1 part of dodecafluoroheptylpropyltrimethoxysilane, 10-13 parts of thermoplastic polyurethane, 3-5 parts of dioctyl azelate, 100-120 parts of high-density polypropylene, 1-2 parts of ammonium molybdate, 0.1-0.3 part of vanadyl acetylacetonate, 0.5-1 part of hexamethylphosphoramide, 10-13 parts of bentonite, 3-4 parts of polytetramethylene glycol, 0.7-1 part of sodium dodecyl sulfate, 1-2 parts of calcium ricinoleate, 0.1-0.2 part of divinyl benzene, 3-4 parts of palm wax and 0.8-2 parts of alkenyl succinic anhydride. The hydrophobic high-elasticity composite material can be used as a gasket material of a large machine and also can be used as a waterproof material and the like, and the hydrophobic high-elasticity composite material is wide in application range and superior in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and relates to polymer composite materials, in particular to a hydrophobic high-elasticity composite material and a preparation method thereof. Background technique [0002] Polypropylene is non-toxic, odorless, low density, strength, rigidity, hardness and heat resistance are better than low pressure polyethylene, and can be used at around 100 °C. It has good dielectric properties and high-frequency insulation and is not affected by humidity, but it becomes brittle at low temperature, not wear-resistant, and easy to age. It is suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common organic solvents such as acids and alkalis have little effect on it, and can be used for tableware; then how to make filler particles better compatible with polypropylene is a key factor determining the quality of composite materials, which affects the quality of polymer inorganic...
