Embodiment 1～6 and comparative example 1～2

[0036] The present invention prepares low-emission and low-odor filling functional masterbatches. The raw material ratios of Examples 1-6 and Comparative Examples 1-2 are listed in the following Tables 1 and 2 respectively. Unless otherwise specified, the percentages refer to weight percentages.

[0037] The preparation method of filling functional masterbatch with low emission and low odor comprises the following steps:

[0038] Add minerals to the mixer, heat to 60 degrees Celsius, then add POP elastomer and dispersant, mix well and then add resin, add deodorant during stirring, and finally add stabilizer, mix well and send into Extrusion and granulation in the two-stage screw granulation unit, the speed of the single-screw extruder is 100 rpm, the speed of the twin-screw host is 600 rpm, and the temperature of each section of the screw is 160 ° C ~ 200 ° C; during the granulation process Using multi-stage vacuum suction, the vacuum pressure is kept at 0.08MPA, and the granu...

Abstract

The invention discloses a low-emission and low-smell filling functional master batch and a preparation method thereof. The low-emission and low-smell filling functional master batch comprises, by weight, 5-30 parts of resin, 1-30 parts of POP polyolefin elastomer, 60-90 parts of mineral, 1-10 parts of a dispersant, 1-10 parts of a deodorant and 0.1-2 parts of a stabilizer. The low-emission and low-smell filling functional master batch is prepared in a multistage vacuum hot air circulation manner through a multi-stage extrusion granulating system. The low-emission and low-smell filling functional master batch can be directly added to plastic and elastomer, the obtained mixture undergoes corresponding molding, and a final product member achieve the effects of low emission, low smell and gooddispersion through different combinations.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a low-emission and low-odor filling 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 to t...
