Problems solved by technology

However, the existing TPE materials with metallic texture have poor mechanical properties and cannot meet the needs of products with different functions.
In order to ensure the better mechanical properties of TPE materials, TPE materials usually need to be sprayed to have a metallic texture. However, the existing spray materials contain harmful substances, and various harmful substances are also produced during the painting process, which pollutes the environment more. Large, not conducive to large-scale applications

preparation example Construction

[0078] A method for preparing a thermoplastic elastomer material according to an embodiment is characterized in that it includes the following operations S110-S140:

[0079] S110. According to parts by weight, mix 30-40 parts of SEBS with 20-30 parts of mineral oil and stir until SEBS fully absorbs mineral oil, and leave for more than 48 hours to obtain SEBS after oil absorption.

[0080] In this step, standing for more than 48 hours can make the mineral oil diffuse into the SEBS, and obtain a stable SEBS after oil absorption.

[0081] In one embodiment, the standing time is 48 hours to 72 hours.

[0082] In one embodiment, the stirring speed is 300r / min-400r / min.

[0083] In one embodiment, the stirring time is 15 minutes to 30 minutes.

[0084] In one embodiment, the operation of S110 is performed at 20°C to 60°C.

[0085] S120, mixing SEBS after oil absorption, 8-25 parts of polypropylene, 10-30 parts of ethylene octene block copolymer, 15-30 parts of polyethylene and 0....

Embodiment 1

[0103] (1) Mix 30 parts of Kraton SEBS 1645 and 20 parts of paraffin base oil at 30° C. and stir for 15 minutes, and leave for 48 hours to obtain SEBS after oil absorption, wherein the stirring speed is 300 r / min.

[0104] (2) The linearity of SEBS after oil absorption, 18 parts of random copolymerized polypropylene (5018T of Taiwan Formosa Plastics), 27 parts of ExxonMobil ethylene octene block copolymer 6202, and 15 parts of Primeman is low. Density polyethylene SP0540, 1 part of silicone masterbatch AT-502 of Shanghai Chunguang Material Technology Co., Ltd., 0.2 part of silver-white fine satin flashing pearl powder (Iriodin111-(1-15 μm) from Merck, Germany) and 0.1 part of Antioxidant 168 was mixed and stirred at 30° C. for 20 minutes to obtain a premixture, wherein the stirring speed was 300 r / min.

[0105] (3) Add 0.6 parts of water-based aluminum-silver paste mirror flash silver (STAPAME×501-(3-15μm) from Erka, Germany) to the premix and mix and stir for 15 minutes at 30...

Embodiment 2

[0108] (1) Mix 40 parts of Kraton SEBS 1643 and 30 parts of mineral oil at 40° C. and stir for 15 minutes, and leave for 72 hours to obtain SEBS after oil absorption, wherein the stirring speed is 320 r / min.

[0109] (2) SEBS after oil absorption, 10 parts of random copolymerized polypropylene (5090T of Taiwan Formosa Plastics), 10 parts of Exxon Mobil ethylene octene block copolymer 3980, 20 parts of Borealis linear low density Polyethylene FB2230, 1 part of silicone masterbatch AT-502 of Shanghai Chunguang Material Technology Co., Ltd., 0.8 part of silver-white fine satin flashing pearl powder (Iriodin 111-(1-15 μm) from Merck, Germany) and 0.1 part of Antioxidant 1076 was mixed and stirred at 40°C for 15 minutes to obtain a premixture, wherein the stirring speed was 320r / min.

[0110] (3) Add 0.2 parts of water-based aluminum-silver paste mirror flash silver (STAPAME×501-(3-15μm) from Eika Germany) to the premix and mix and stir for 15min at 40°C to obtain a mixture, wherei...

Abstract

The invention relates to a thermoplastic elastomer material and a preparing method thereof. The thermoplastic elastomer material is prepared from, by weight, 30-40 parts of SEBS, 20-30 parts of mineral oil, 8-25 parts of polypropylene, 10-30 parts of an ethylene-octene segmented copolymer, 15-30 parts of polyethylene, 0.2-0.8 part of pearl powder and 0.2-0.6 part of flash silver. The thermoplasticelastomer material has excellent mechanical performance and has metallic texture without spray coating.

Description

technical field [0001] The invention relates to a thermoplastic elastomer material and a preparation method thereof. Background technique [0002] PVC (Polyvinylchloride) material, the main component is polyvinyl chloride, is a widely used synthetic material. However, during the processing of PVC materials, harmful gases and waste products that are not easy to degrade and handle will be produced, and some additives will be volatilized during the use of products made of PVC materials, which will not only endanger human health, but also cause environmental pollution. [0003] With the continuous improvement of people's requirements for quality of life and the continuous strengthening of environmental protection awareness, TPE (Thermoplastic Elastomer, thermoplastic elastomer) materials emerged as the times require and entered people's lives. In order to increase the ornamental and aesthetic feeling of the product, it is usually required that the TPE material has a metallic te...
