preparation example Construction

[0049] The preparation method of above-mentioned thermoplastic elastomer sealing strip material, comprises the steps:

[0050] Step 1. Weigh 15-40 parts of white oil and 0.1-1.0 parts of lubricant according to parts by weight, mix the two, and stir evenly;

[0051] Step 2: Weigh 20-35 parts of SEBS according to parts by weight and add them into the mixture obtained in Step 1 and stir evenly until SEBS completely absorbs the white oil;

[0052] Step 3. Weigh 8-15 parts of grafted SEBS, 15-25 parts of modified organosiloxane, 5-10 parts of mineral filler, 10-25 parts of mineral filler, 0.1-0.5 parts of antioxidant according to the weight fraction, and add The mixed solution obtained in step 2 is stirred evenly; and

[0053] The fourth step is to use a twin-screw extruder to plasticize, extrude, cool, and granulate to obtain the thermoplastic elastomer sealing strip material.

[0054] The modified organosiloxane is introduced into the above-mentioned thermoplastic elastomer sea...

Abstract

The invention relates to a thermoplastic elastomer sealing strip material and a preparation method thereof. The thermoplastic elastomer sealing strip material is composed of the following raw materials in parts by weight: 20-35 of SEBS (Styrene-Ethylene-Butylene-Styrene), 8-15 of grafting SEBS, 15-40 of white oil, 15-25 of modified organosiloxane, 5-10 of mineral filler, 10-25 of polyolefine, 0.1-1.0 of lubricating agent, and 0.1-0.5 of oxidation resistant. The modified organosiloxane is introduced in the thermoplastic elastomer sealing strip material, since silicon-oxygen bond has high bond energy and large space parallactic angle, therefore, the thermoplastic elastomer sealing strip material has more excellent thermostable performance compared with that of the conventional TPE (thermoplastic elastomer) in SBC (single board computer) class.

Description

【Technical field】 [0001] The invention relates to a sealing strip material and a preparation method thereof, in particular to a thermoplastic elastomer sealing strip material and a preparation process thereof. 【Background technique】 [0002] With the rapid development of my country's home appliance industry and automobile industry, the demand for sealing strips is increasing, and the requirements are getting higher and higher. my country has become a big consumer of automobiles and home appliances, so sealing strips have a broad market and prospects. . [0003] With the development of industry, there are more and more new sealing strip materials, among which thermoplastic elastomer material is one of the most prominent environmental protection materials, which are mainly divided into polyolefin (TPO, TPV), polyurethane (TPU) , polyvinyl chloride (TPVC), polyamide (TPAE) and other types of thermoplastic elastomers. [0004] Thermoplastic elastomer (thermoplastic elastomer, r...
