Low-temperature-resistant automobile nylon composite and preparation method thereof

Abstract

The invention discloses a low-temperature-resistant automobile nylon composite and a preparation method thereof. The low-temperature-resistant automobile nylon composite is prepared from the following raw materials by weight: 45 to 65 parts of nylon 11, 30 to 40 parts of nylon 1010, 15 to 20 parts of polyoxymethylene, 17 to 23 parts of bis[2-(2-butoxyethoxy)ethyl] adipate, 12 to 18 parts of di-iso-butyl ester nylon acid, 10 to 15 parts of potassium hexatitanate whisker, 4 to 7 parts of zirconium silicate, 2.5 to 4.5 parts of isocetyl palmitate, 2 to 3 parts of hydroxystearic acid, 1 to 2 parts of barium laurate, 1 to 2 parts of barium myristate, 10 to 15 parts of resorcinol monobenzoate, 3 to 6 parts of vitamin E, 2 to 4 parts of distearyl alcohol pentaerythritol diphosphite, 1 to 2 parts of hydroxyl-aluminum p-tert-butyl benzoate, 1.5 to 2.5 parts of 3,4-dimethyl dibenzylidene sorbitol, 10 to 15 parts of oil shale residue, 8 to 12 parts of calcined clay, 5 to 10 parts of barite powder and 10 to 15 parts of modified kaolin. The nylon composite provided by the invention has excellent low temperature performance and can even be normally used at a low temperature of -50 DEG C; moreover, the nylon composite has high impact strength toughness, bending strength and rigidity, effectively prolongs the service life of a nylon material and broadens the application scope of the nylon material.

Description

Technical field [0001] The invention relates to a low-temperature resistant automobile nylon composite material and a preparation method thereof, and belongs to the field of nylon materials. Background technique [0002] In recent decades, the automobile industry has developed rapidly. The main directions of automobile research are light weight, energy saving and consumption reduction, emission reduction and improved safety performance. The application of functional parts made of plastics in automobiles has become more and more extensive. Nylon has been widely used in automobiles due to its excellent comprehensive properties such as high strength, heat resistance, oil resistance, chemical resistance, self-lubricating, self-extinguishing, anti-vibration, anti-noise, easy processing, recyclability, and sufficient sources. The toughness of nylon materials currently on the market for automobiles is prone to low-temperature brittleness under low-temperature conditions, which makes it ...
