Low odor weather resistant PA (polyamide)/ABS (acrylonitrile-butadiene-styrene) composite material

Abstract

The invention discloses a low odor weather resistant PA (polyamide) / ABS (acrylonitrile-butadiene-styrene) composite material which comprises the following components by weight: 30-50 parts of PA; 35-60 parts of ABS; 5-15 parts of a compatibility agent; 5-8 parts of reaction type castor oil; 3-6 parts of a compound antioxidant; 1-2 parts of an initiating agent t; 2-5 parts of a heat stabilizer; and 3-6 parts of an activated carbon-nano TiO2 Composite. By use of synergistic effect of various components, according to the principle of combining physical adsorption and chemical bonding, odor and small molecular substances in the PA / ABS composite are removed, amine, sulfur and mercaptan odor matters in the material are chelated for forming a new stable compound so as to improve the material smell, the material weather resistance is optimized, and the low odor weather resistant PA (polyamide) / ABS (acrylonitrile-butadiene-styrene) composite material has good social benefit and economic benefit.

Description

technical field [0001] The invention relates to a composite material, in particular to a low-odor and weather-resistant PA / ABS composite material; it belongs to the technical field of polymer materials. Background technique [0002] Polyamide (PA), commonly known as nylon, is a thermoplastic engineering plastic widely used in automobiles, electronics, machinery and other fields. It has excellent wear resistance, impact resistance and self-lubricating properties, and is resistant to various chemicals, but It is not resistant to strong alkali, and has high water absorption, low heat distortion temperature, and large creep. These shortcomings limit its application to a large extent. The blending modification of nylon with acrylonitrile-butadiene-styrene (ABS) can improve the above-mentioned shortcomings of nylon and broaden the application field of nylon. The PA / ABS composite material prepared by blending not only has the wear resistance, impact resistance and self-lubricating...

AI Technical Summary

Problems solved by technology

The PA / ABS composite material prepared by blending not only has the wear resistance, impact resistance and self-lubricating properties of nylon, but also has the toughness and rigidity of ABS. In order to achieve good compatibility between the two, it is necessary to add some Additives, which lead to a strong odor of the product, coupled with the presence of various small molecular impurities in the raw materials, cause the product to release an unpleasant smell during subsequent use, which affects the market reputation of the product. In view of this, it is urgent to improve
