[0004] At present, most of the main thermoplastic elastomer (TPE) materials on the market are produced by international companies such as GLS, Santoprene, Polyone and TPE in the United States. In contrast, domestic production of thermoplastic elastomer (TPE) materials There are many manufacturers, but most of them focus on the development of the low-end TPE market. In the high-end such as PA, POM overmolding TPE and higher-end TPV, TPSiv, etc., there are still relatively few domestic companies involved.

Embodiment 1
[0028] Embodiment 1 (preparation of FLEXBOND-1026BFENC001 product)
[0029] Take 40 parts of SEBS resin, 45 parts of TPU resin, 12 parts of SEBS-MAH, 5 parts of SMA, 2 parts of UV-P, and 2 parts of other additives. Then add SEBS resin, SEBS-MAH, TPU resin, SMA, UV-P, and other additives in sequence, mix in a high-speed mixer at 50°C for 10 minutes, and then granulate through a counter-rotating twin-screw extruder. The properties of the obtained materials are shown in Table 1.
[0032] Embodiment 2 (preparation of FLEXBOND-1028AFE NC004 product)
[0033] Take 30 parts of SBS resin, 65 parts of TPA resin, 10 parts of SBS-MAH, 7 parts of SMA, 1.5 parts of UV-P, and 3 parts of other additives. Then add SBS resin, SBS-MAH, TPA resin, SMA, UV-P, and other additives in sequence, mix in a high-speed mixer for 7 minutes at 70°C, and then granulate through a counter-rotating twin-screw extruder. The properties of the obtained materials are shown in Table 1.
[0036] It can be seen from the product performance that the FLEXBOND series products produced have multiple coating uses, excellent physical and mechanical properties and weather resistance, and have strong market competitiveness.

Abstract
The invention discloses a thermoplastic elastomer and a preparation method thereof. The thermoplastic elastomer comprises the following components in parts by weight: 20-70 parts of oil charge hydrogenated styrene resin, 20-80 parts of strong-polarity polymer resin, 6-25 parts of compatilizer, 1-19 parts of processing aid and 1-4 parts of weatherproof agent. On the basis of satisfying the usability of TPE material, the invention obtains ideal processing flowability and totally can shape film-wall workpieces by screening and matching the oil charge hydrogenated styrene resin, the strong-polarity polymer resin, the efficient compatilizer, efficient weatherproof agent and various processing aids. The produced FLEXBOND series product has the following advantages: (1) multiple cladding: acrylonitrile butadiene styrene acrylonitrile butadiene styrene (ABS), polycarbonate (PC) / ABS, PC, polyacetal (POM) and polybutylece terephthalate (PBT) are coated and shaped under different processing conditions; (2) excellent physical and mechanical properties; (3) good weather resistance: the product can satisfy the storage and use requirements of products; (4) good material flowability and easy shaping, and capability of satisfying precise shaping requirements; and (5) capability of conforming to the environmentally-friendly requirement.
Description
technical field [0001] The present invention relates to a thermoplastic elastomer. Background technique [0002] Thermoplastic Elastomer (TPE, Thermoplastic Elastomer), also known as Thermoplastic Rubber (TPE, Thermoplastic Rubber), is a new type of elastomer. With the development, many industrialized products have emerged, becoming a strong competitor with traditional vulcanized rubber. In recent years, the rapid development of my country's economy has driven the development of industries such as automobiles, construction, wire and cable, and consumer goods, and the market demand for thermoplastic elastomer products is also growing. As thermoplastic elastomers are listed as the national "863 Plan" and supporting projects, the market development prospect is getting brighter and brighter. [0003] Thermoplastic elastomer (TPE) materials have the advantages of recyclability, light weight, high resilience, and excellent touch, so they are increasingly used in high-end power t...
