Problems solved by technology

However, spraying matte paint will greatly increase the processing cost of interior parts and cause environmental pollution; although adding large particle size inorganic fillers to the material can significantly reduce the gloss of the material, it will lead to a significant decrease in the impact strength and fluidity of the material ; while adding pre-crosslinked rubber particles to the material can achieve a good matte effect on the surface of the part, but it seriously affects the fluidity and heat resistance of the material

Abstract

The invention relates to a matte-level heat-resistant ABS modified material and a preparation method thereof and belongs to the technical field of materials. The matte-level heat-resistant ABS modified material is prepared from, by weight, 60-80% of ABS resin, 5-20% of surface modified carbon fiber, 5-15% of heat-resistant modifier, 1-5% of impact modifier, 1-5% of matting agent, 1-5% of nano filler, 0.5-1% of antioxidant and 0.5-1% of light stabilizer. The matte-level heat-resistant ABS modified material uses the nylon ABS resin as a basic body, the resin is strengthened by adding the surface modified carbon fiber and jointly using the heat-resistant modifier and the impact modifier, the strength, high temperature resistance and impact resisting performance of the material are improved, the soft and even matting effect is produced on the surface of a finished product, and further the high-matte-level and high-heat-resistance requirements of automotive interior accessories in the automobile industry are met. In addition, the preparation method of the matte-level heat-resistant ABS modified material is simple and low in cost and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a matte grade heat-resistant ABS modified material and a preparation method thereof, belonging to the field of material technology. Background technique [0002] Styrene-butadiene-acrylonitrile copolymer (ABS) is an engineering plastic with excellent comprehensive properties, high impact strength, good gloss and dimensional stability, easy to dye, wear-resistant and easy to form, and is widely used Used in auto parts (instrument panels, tool hatches, wheel covers, mirror boxes, etc.), electric tool casings, typewriter keyboards, etc.; but the heat-resistant temperature of general-purpose ABS resin is low, and the heat distortion temperature of 0.45MPa is generally only about 90°C , when it is used in the central panel of the car, the air outlet of the air conditioner, the upper and lower covers of the steering wheel, and the sun visor, it cannot meet the requirements of the automotive interior parts with heat resistance (0.45MP...
