Problems solved by technology

The elastomer material of the present invention is based on the synthesis of traditional thermoplastic polyurethane elastomers, introducing hydroxyl-terminated solution-polymerized styrene-butadiene rubber as a soft segment, while maintaining the polyurethane elastomer material itself is environmentally friendly, highly wear-resistant, oil-resistant, chemical-resistant, On the basis of the advantages of low rolling resistance, combined with the excellent flex resistance and excellent dynamic mechanical properties of solution-polymerized styrene-butadiene rubber, the glass transition temperature of polyurethane elastomers is adjusted. At the same time, white carbon black is added to effectively puncture the water film. The anti-wet skid resin overcomes the shortcomings of the existing shared bicycle solid tires such as poor wet skid resistance, and has excellent comprehensive performance. The use of the material described in the present invention to prepare solid tires is bound to have broad development space in the future shared bicycle tire industry

Embodiment 1

[0071] The preparation process of the high anti-wet skid elastomer nanocomposite in this embodiment is as follows:

[0072] 1) Preparation of naphthalene lithium initiator: with reference to the literature "Research on Negative Dilithium Initiator System" (Han Bingyong et al., Synthetic Rubber Industry, 1999-01-15, 22 (1): 5-8) Preparation: the polymerization bottle was pumped Vacuum, flame baking and filling with argon are repeated 3 times, then add naphthalene, lithium, polar additives, benzene, react at room temperature, finally add butadiene or isoprene, and filter to get naphthalene lithium short chain initiator. The initiator concentration was calibrated by double titration method, and the initiator concentration was 1mol / L.

[0073] 2) Distillation of ethylene oxide: Get 100g of calcium hydride and grind it into powder, add it to 1L of ethylene oxide and soak it for 24h, and steam the ethylene oxide at room temperature under a nitrogen atmosphere.

Abstract

The invention discloses a high wet-skid resistance elastomer nanocomposite for a solid vehicle tire and a preparation method. The composite is prepared by mixing the following raw materials in parts by weight: 100 parts of substrate material, 5-25 parts of white carbon black and 10-30 parts of wet-skid resisting resin; the wet-skid resisting resin is styrene resin, C5C9 copolymer resin, C9 resin, coumarone resin or terpene resin; and the substrate material is selected from a solution-polymerized styrene butadiene rubber-polyurethane elastomer material. According to the invention, on the basis of maintaining the advantages of environmental protection, high abrasion resistance, oil resistance, chemical resistance and low rolling resistance of the polyurethane elastomer material, the excellent flexing resistance and excellent dynamic mechanical property of the solution-polymerized styrene butadiene rubber are combined for regulating the glass-transition temperature of the polyurethane elastomer, and meanwhile, the white carbon black is added for effectively puncturing a water film, the wet-skid resisting resin is added for further promoting the wet-skid resistance and the comprehensive use performance is excellent.

Description

technical field [0001] The present invention relates to the technical field of tires, and furthermore, relates to a high wet-skid-resistant elastomer nanocomposite material for solid rickshaw tires and a preparation method thereof. Background technique [0002] Bike sharing refers to the cooperation between enterprises and the government to provide bicycle sharing services in public service areas, subway stations, bus stations, commercial areas, residential areas, campuses, etc. It is a new form of sharing economy. So far, the types of shared bicycles in the country include Mobike, ofo bicycles, small blue bicycles, cool bicycles, 1-step bicycles, Youyou bicycles, Qibei, Panda bicycles, cloud bicycles, Kuaitu travel, etc. kind. Statistics show that by the end of 2016, the overall number of users in China's shared bicycle market has reached 18.86 million, and it is expected to reach 50 million users by the end of this year. The emergence and popularity of shared bicycles is...
