Embodiment Construction

[0012] A high-impact automotive nylon composite material, made of the following parts by weight of raw materials: nylon 1250, nylon 640, polyadipate-terephthalate-butylene glycol 30, methyl methacrylate-butadiene -Styrenic copolymer 18, spinel powder 22, boron mud 14, aluminum titanate fiber 12, cork powder 8, tetraisopropyl bis(dioctyl phosphite acyloxy) titanate 2, C5 petroleum resin 12 , Magnesium oxide 2.5, Calcium benzoate 2, Coal pitch 6, Stearyl tributyl citrate 12, Dicyclohexyl phthalate 12, Basic lead silicate 2.5, Barium stearate 1.5, Stearin Zinc acid 2, modified kaolin 18, antioxidant 30102;

[0013] The preparation method of the modified kaolin is as follows: (1) Soak the kaolin in a 20% hydrochloric acid solution for 1 hour, filter, wash with distilled water until neutral, dry, calcinate at 680°C for 1 hour, and cool to room temperature naturally. Crushing, sieving, adding water and ultrasonic dispersion to make a suspension with a concentration of 55%, ready for u...

Abstract

The invention discloses a high-impact-resistance automobile nylon composite and a preparation method thereof. The high-impact-resistance automobile nylon composite is prepared from the following raw materials by weight: 40 to 60 parts of nylon 12, 30 to 50 parts of nylon 6, 25 to 35 parts of poly(butyleneadipate-co-terephthalate), 15 to 20 parts of methacryIate-butadiene-styrene copolymer, 18 to 24 parts of spinel powder, 12 to 16 parts of boron mud, 10 to 15 parts of aluminum titanate fiber, 6 to 12 parts of cork powder, 1.5 to 2.5 parts of tetraisopropyl di(dioctylphosphate) titanate, 10 to 15 parts of C5 petroleum resin, 2 to 3 parts of magnesium oxide, 1.5 to 2.5 parts of calcium benzoate, 4 to 8 parts of coal tar pitch, 10 to 15 parts of octodecyl acyl tributyl citrate, 8 to 14 parts of dicyclohexyl phthalate, 2 to 3 parts of basic lead silicate, 1 to 2 parts of barium stearate, 1 to 2 parts of zinc stearate, 15 to 20 parts of modified kaolin and 1.5 to 2.5 parts of an antioxidant 3010. The nylon composite provided by the invention has greatly improved notch impact strength while maintaining high tensile strength and bending strength and has excellent shock resistance.

Description

Technical field [0001] The invention relates to a high-impact 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 safety improvement. The application of functional parts made of plastic 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. At present, the impact resistance of single reinforced or toughened nylon materials on the market can no longer meet the actual needs. In order to meet the requirements of use and expand...
