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 barrel. The temperature control of each section of the main barrel (from the feeding port to the exit of the machine head) 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 low-odor ABS resin composition for automobile interior and a preparation method thereof. The resin composition comprises, by weight, 62-97.9% of ABS resin obtainedby a bulk polymerization method, 0-30% of a heat resistant agent, 1-5% of a matting agent, 0.1-1.5% of a low odor additive and 1-1.5% of a processing aid. The preparation method can effectively reducethe gloss of the material by using the ABS resin with larger particle sizes and a polymer having a high crosslinked structure. The hydrated salt substance can effectively remove low molecular substances through the double vacuum process due to the presence of bound water. The dehydrated salt material can form separated dispersion points in the polymer, and each dispersion point forms a separatedprotrusion so that the gloss of the material can be further reduced. Pigment carbon black has a strong polar group on its surface and can react with polar molecules (odor sources) released from the resin under heat action so that the material odor is reduced.

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...
