Abstract

The invention discloses an anti-static polyurethane (PU) elastomer and a preparation method and application thereof. The anti-static PU elastomer is prepared from, by weight, 85-88 parts of component A and 12-15 parts of vulcanizing agent. The component A is prepared from, by weight, 70-75 parts of polyhydric alcohols, 20-25 parts of curing agent and 1-5 parts of antistatic agent. The anti-static PU elastomer has a perpetual anti-static property, can avoid the phenomenon that the anti-static capacity loses efficacy due to long-time using or frequent cleaning, and can be widely applied to the fields such as electrons, medical equipment, automobile parts, instruments and apparatuses.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an antistatic unglue and its preparation method and application. Background technique [0002] Youli glue, also known as polyurethane PU elastomer, is a new type of material with good strength, small compression deformation, smooth surface, glossy and dense, between plastic and rubber, with the rigidity of plastic and The elasticity of rubber can be used for a long time in the temperature range of -40°C to 80°C. Its wear resistance and self-lubrication are superior to most engineering plastics, and it also has good oil resistance and oxidation resistance. It is currently A widely used alternative to rubber. [0003] When Uniglue is used with instruments and equipment, friction with air, water vapor, dust and other particles may easily generate static electricity. If it is used in medical equipment, excessive static electricity will generate electric sparks, which may cause...
