Embodiment 1～5 and comparative example l～3

[0029] After the dry ABS resin, heat-resistant agent, matting agent, low-odor additive, antioxidant, light stabilizer, lubricant are mixed by the composition formula in Table 1, join the twin-screw extruder (screw diameter is 35mm , aspect ratio L / D=48) in the main cylinder. The temperature control of each section of the main barrel (from the feeding port to the nozzle outlet) is 220°C, 220°C, 230°C, 230°C, 230°C, the twin-screw speed is 350 rpm, and the extruded material is cut after cooling in the water tank. grains, the sample is obtained.

Abstract

The invention discloses a low-gloss and low-odor ABS resin composition for automobile interior decoration and a preparation method thereof. 1-5% of additives; 0.1-1.5% of low-odor additives; 1-1.5% of processing aids. The present invention introduces a polymer with a high cross-linking structure by using the ABS resin with a larger particle size, which can effectively reduce the gloss of the material. The low-molecular substances can be removed more effectively under the double-vacuum process. At the same time, the dehydrated salt substances can form independent dispersion points in the polymer, and each dispersion point forms an independent protrusion, which can further reduce the material. Gloss, due to the presence of strong polar groups on the surface of pigment carbon black, it can react with the polar molecules (odor source) released from the resin under the action of heat, thereby reducing the material odor.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a low-gloss and low-odor ABS resin composition for automobile interior decoration and a preparation method thereof. Background technique [0002] In order to further ensure the driver's safe driving, eliminate potential safety hazards as much as possible, and prevent the driver from affecting the driver's vision due to the high gloss of the interior parts during driving, thereby causing potential safety hazards, the automotive industry has strict regulations on the glossiness of interior materials. Put forward more stringent requirements, such as Volkswagen requires the glossiness of interior material parts to be below 3.5. On the other hand, with the continuous improvement of the automotive industry's requirements for the air quality inside the car, more and more car OEMs pay special attention to the impact of the smell in the car on the comfort of the driver and pas...
