Problems solved by technology

Physical adsorption can have a good effect in short-term room temperature, but since adsorption and removal are a reversible process, when used at high temperature or for a long time, the physically adsorbed substances will still be emitted, endangering human health; and extraction The removal method can effectively reduce the emitted substances in the material, but it can only be improved during the extrusion process. After the material is processed in the later stage, such as after injection molding, the material will emit small molecular substances due to thermal oxygen degradation. , resulting in a substantial increase in sporadic
Most of the current patents and reports are dedicated to reducing the emission level of itself, reducing the emission of final products by reducing the emission base, and there are few reports on automotive interior materials that actively control emission substances

Abstract

The invention discloses a self-formaldehyde-clearing and heat-resistant acrylonitrile butadiene styrene (ABS) material and a preparation method thereof. The material is prepared from, by weight, 75-95 parts of ABS resin, 4-20 parts of heat resistant agent, 0.5-5 parts of formaldehyde clearing master batches, 0.1-1 part of formaldehyde clearing agent and 0.5-1 part of other auxiliaries. During preparation, the ABS resin, the heat resistant agent and other auxiliaries are mixed and fed through a main feeding port of a twin-screw extruder; the formaldehyde clearing master batches and the formaldehyde clearing agent are fed through the rear section of the extruder, and the material can be obtained through extruding and granulating. Thanks to the method, the content of formaldehyde in granules can be reduced by 40%, the content of formaldehyde in sealed space is reduced by 50% or above, and the content of other volatile organic compounds is reduced by 10% to 20% at the same time, so that the effects of controlling emission of material formaldehyde for a long time and inhibiting the content of formaldehyde in space are achieved.
