Embodiment 1

[0038] The preparation of embodiment 1 dust-proof and heat-resistant masterbatch

[0039] The dust-proof and heat-resistant masterbatches 1-9 were prepared using the components and weight ratios described in Table 1. The preparation steps of the dust-proof and heat-resistant masterbatch are as follows:

[0040] Weigh a certain amount of fluorinated graphene, perfluoroalkyl acrylic additives, SMA, ABS resin and antioxidants in parts by weight and put them into a high-speed mixer and stir for 5-30 minutes to obtain a mixture; The screw extruder is extruded and granulated. The temperature of the twin-screw extruder is 200-230°C, the screw speed is 180-600 rpm, and the vacuum degree is greater than 0.09MPa.

Abstract

The invention provides dustproof and heat-resistant ABS resin and a preparation method thereof, and belongs to the technical field of modified resin. The dustproof and heat-resistant ABS resin comprises the following components in parts by weight: 20 to 35 parts of ABS resin, 65 to 80 parts of SAN resin, 5 to 20 parts of dustproof and heat-resistant masterbatch, 0.1 to 1 part of a lubricant and 0.1 to 1 part of an antioxidant. Compared with the prior art, the dustproof and heat-resistant ABS resin has the advantages that by introducing fluorinated graphene, a perfluoroalkyl acrylic additive and SMA into the dustproof and heat-resistant masterbatch, a layer of film with high heat resistance and conductivity and a good conductive function can be formed on the surface of the ABS resin; and the dustproof and heat-resistant ABS resin has excellent heat resistance and dustproof performance, and can be applied to automotive interior parts such as an automobile instrument panel and a decorative frame which have relatively high dustproof and heat-resistant requirements.

Description

technical field [0001] The invention relates to a modified resin, in particular to a dust-proof and heat-resistant ABS resin and a preparation method thereof. Background technique [0002] Automotive interior parts will receive energy from the car itself or sunlight, mainly the energy produced by sunlight, especially the parts around the instrument panel in front of the car are in the direct sunlight. The heat resistance requirements of the parts are very high. [0003] The interior colors of modern cars are mainly black, beige and brown, especially the black interior parts can better reflect the dynamic trend, and are more and more popular among young people. However, black parts can absorb more energy than light-colored parts, and the temperature of the part will be very high under intense roasting, so the heat resistance requirements for black parts will be higher. Moreover, due to the need for beauty and cleanliness, the parts are also required to have a better dustpro...
