Low-emission, low-odor and dustproof functional master batch and preparation method thereof

Abstract

The invention discloses low-emission, low-odor and dustproof functional master batch and a preparation method thereof. The low-emission, low-odor and dustproof functional master batch is prepared fromcomponents of raw materials in percentage by weight as follows: 10%-80% of resin, 5%-80% of a thermoplastic elastomer, 5%-40% of an antistatic agent, 1%-10% of a deodorant and 0.1%-2% of a stabilizer. The low-emission, low-odor and dustproof functional master batch is prepared through a two-stage extrusion and granulation system in a double-stage vacuum and hot air circulation manner. The low-emission, low-odor and dustproof functional master batch can be directly added to plastic and the elastomer for corresponding forming, and a final product workpiece realizes the effects of low emission,low odor, good dustproof and dispersion properties and excellent comprehensive mechanical property through different combinations.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a low-emission, low-odor and dust-proof functional masterbatch and a preparation method thereof. Background technique [0002] In the automobile and construction industries, higher requirements are put forward for the emission of harmful substances (such as formaldehyde, VOC, haze) and odor in automobiles and construction spaces. Therefore, the low-emission and low-odor characteristics of plastic and elastomer components used in such industries will definitely become a development trend for future applications. [0003] At present, the following measures can be taken to reduce odor: 1. Use low-odor substitutes to replace additives that emit unpleasant odors; 2. Use purer resins; 3. Add adsorbents, including physical adsorption and chemical reactions Methods. Among them, the third method is a method widely used at present. [0004] Physical adsorption mostly refers ...
