Embodiment 1

[0050] Use the following weights of ingredients:

[0051]

[0052] In terms of weight percentage, the formula of the self-made low-emission, low-odor and dust-proof functional masterbatch in this embodiment is as follows:

[0053]

[0054] The preparation process of the low-emission, low-odor and dust-proof functional masterbatch is as follows: mixing thermoplastic elastomer and resin, adding antistatic agent, deodorant, and stabilizer during the stirring process, and sending it into the double-stage screw after mixing evenly Extrusion and granulation in the granulation unit. The two-stage screw granulation unit is composed of a single-screw extruder and a twin-screw extruder. 200°C; the speed of the twin-screw main engine is 600 rpm, and the temperature of each section of the screw is 160°C-200°C; double vacuum suction is used during the granulation process, and the vacuum pressure is kept at 0.08MPA. A 4-hour ventilation cycle was carried out in a blast oven to finall...

Embodiment 2～5

[0062] Except for the different formulations of self-made low-emission, low-odor and dust-proof functional masterbatches, the types of other raw materials are unchanged, and the preparation process is the same as in Example 1. The specific low-emission, low-odor and dust-proof functional masterbatch formulations are shown in Table 2 below:

Abstract

The invention discloses a dustproof, low-emission and low-odor thermoplastic elastomer. The dustproof, low-emission and low-odor thermoplastic elastomer comprises the following raw materials in percentages by weight: 5 to 70% of matrix resin, 5 to 90% of a thermoplastic elastomer, 0 to 50% of filling oil, 0 to 40% of a mineral filling agent, 1 to 20% of low-emission, low-odor and dustproof functional master batch and 0.1 to 2% of a stabilizing agent. The dustproof, low-emission and low-odor thermoplastic elastomer is prepared through manners of twin-screw extrusion granulation, double-stage vacuum and hot-air circulation. The thermoplastic elastomer material has the characteristics of dust prevention, low emission and low odor, can be separately formed, can be post-formed with a polypropylene material, and has good low-temperature resistance and high-temperature-resistant compressibility and excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a dust-proof, low-emission and low-odor thermoplastic elastomer and a preparation method thereof. Background technique [0002] Due to its excellent performance, easy processing and reasonable price, thermoplastic elastomer materials are rapidly replacing thermosetting elastomers in more and more fields such as construction, daily necessities, kitchen supplies, and automobiles. [0003] In the prior art, the thermoplastic elastomer materials conventionally sold in the market have an unpleasant smell when heated, and even emit an unpleasant smell at room temperature. It contains some additives and plasticizers, which may seep or vaporize and affect the health of users. [0004] A Chinese patent document with publication number CN 104530628 A discloses a TPE material that can be used for automotive interiors and a preparation method thereof. The material includes ...
