Abstract

The invention discloses a low-odor low-VOC (volatile organic compound) thermoplastic plastic, which comprises the following components by weight: 40-90 parts of a polymer base material, 1-50 parts ofinorganic filler and 0-20 parts of additives, wherein the inorganic filler comprises attapulgite. According to the invention, the porous mineral attapulgite is selected as the inorganic filler, pore channels and pores of the attapulgite run through the inside of the whole crystal structure, so that the attapulgite has the function of a molecular sieve, and also because of a large specific surfacearea, the attapulgite has very strong adsorption performance.

Description

technical field [0001] The invention relates to the field of automotive interior materials, in particular to a low-odor and low-VOC thermoplastic. Background technique [0002] Thermoplastics have been widely used in the automotive industry due to their high cost performance, low density, excellent heat resistance, chemical resistance, easy molding and recycling. However, since the main chain of the thermoplastic matrix will degrade under the action of light, heating, mechanical force, oxidation reaction, etc., alkanes, aldehydes, ketones and other substances will be generated through free radical reactions, resulting in VOC (Volatile Organic Compounds) in polymer matrix composites. , volatile organic compounds) content increased. There are many reasons for the air pollution in the car. Because the release of VOC will cause a certain degree of harm to human health, people will feel dizzy, nauseous, and unable to concentrate in such an environment for a long time. Excessive...
