Abstract

An anti-load anti-fatigue type TPE thermoplastic elastomer and a preparing method thereof are disclosed and belong to the technical field of polymer materials. The elastomer is characterized by comprising, by weight, 46-50 parts of SEBS, 8-12 parts of a POE elastomer, 16-20 parts of copolymerized PP, 28-32 parts of liquid polybutylene (PB), 0.4-0.8 part of an antioxidant, 11-15 parts of calcium carbonate and 0.6-0.8 part of a processing lubricant. The method includes weighing most of the materials, adding the weighed materials into a high-speed mixer, mixing the materials, heating the mixtureto 65-75 DEG C, then adding the liquid polybutylene into the mixture, performing high-speed mixing until the liquid component is completely absorbed by the material mixture, cooling the mixture, and granulating the mixture. Compared with TPE materials in the prior art, the TPE thermoplastic elastomer has good anti-load and anti-fatigue properties, and when the TPE thermoplastic elastomer is used as a hub covering material, the TPE thermoplastic elastomer has good resilience and high adhesive force, and the service lifetime of the TPE thermoplastic elastomer is far longer than that of the TPE materials in the prior art.

Description

technical field [0001] A load-resistant and fatigue-resistant TPE thermoplastic elastomer and a preparation method thereof belong to the technical field of polymer materials. Background technique [0002] Thermoplastic elastomers (TPE) are elastomers that combine the elasticity of rubber with the processability of thermoplastics. Because TPE material is environmentally friendly, non-toxic and safe, it has excellent colorability and soft touch, it has better weather resistance, fatigue resistance and temperature resistance, excellent processing performance, and can be recycled, which can effectively reduce the cost of use. In addition, since no vulcanization is required in its production process, the production process is greatly simplified and energy consumption is effectively reduced. TPE materials can be overmolded, coated and bonded with PP, PE, PC, PS, ABS and other base materials, or can be molded separately. Compared with traditional thermosetting rubber, thermoplast...
