Abstract

The invention relates to the technical field of wear-resistant films, in particular to a polyurethane film with high wear resistance. The polyurethane film is prepared from isophorone diisocyanate, polyethylene glycol, ethylene glycol, trimethylolpropane, a titanate coupling agent, a nonionic surfactant, a defoaming agent, a pH regulator, a flame retardant, a filling agent and the balance of deionized water. The invention also discloses a preparation method of the polyurethane film with high wear resistance. The method comprises preparation steps as follows: S1, weighing and proportioning; S2,stirring and mixing; S3, plastification; S4, calendaring molding; S5, modified pretreatment; and S6, plasma modification. The polyurethane film and the preparation method have the benefits as follows: the formula is scientific and reasonable, the surface of the plasma modified film is uniform and compact, the wear resistance and adhesion of the film are substantially improved, the process is simple, the cost of raw materials is low, and large-scale application can be realized.

Description

technical field [0001] The invention relates to the technical field of wear-resistant films, in particular to a highly wear-resistant polyurethane film and a preparation method thereof. Background technique [0002] As the application fields of polymer films become more and more extensive, the requirements for the properties of film materials are getting higher and higher. Commonly used polysulfone and polyolefin films can no longer fully meet the market demand. In this case, polyurethane films have emerged as the times require. Due to the characteristics of the molecular structure of polyurethane, people can change its elasticity, hardness and hydrophilicity by adjusting the proportion of polyurethane block components. Therefore, polyurethane film, like polyurethane elastomer, has excellent high tension, high tensile force, waterproof, breathable, toughness and aging resistance, and also has excellent biological and blood compatibility and chemical resistance. It is widely...
