Embodiment 1～5 and comparative example 1～2

[0038] The present invention prepares low-emission, low-odor and dust-proof functional masterbatches. The raw material ratios of Examples 1-5 and Comparative Examples 1-2 are listed in Tables 1 and 2 below. Unless otherwise specified, the percentages refer to weight percentages.

[0039] The preparation method of low emission and low odor dustproof functional masterbatch comprises the following steps:

[0040] Mix the thermoplastic elastomer with the resin, add antistatic agent, deodorant and stabilizer during the stirring process, mix evenly and send it to the two-stage screw granulation unit for extrusion granulation, the two-stage screw granulation unit It consists of a single-screw extruder and a twin-screw extruder. The speed of the single-screw extruder is 100 rpm, and the temperature of each section of the screw is 160 ° C ~ 200 ° C; the speed of the twin-screw host is 600 rpm. The temperature ranges from 160°C to 200°C; double vacuum suction is used during the granulat...

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 ...
