Problems solved by technology

[0003] Under the strong light, the temperature inside the car rises rapidly. In order to solve this problem, automotive insulation films emerge one after another, which can effectively slow down the temperature rise inside the car, but the actual effect still cannot reach the higher level in actual use. At the same time, with the improvement of various requirements for use, the pursuit of comprehensive performance such as wear resistance, heat insulation, UV protection, and no residue is gradually enhanced. There is an urgent need to obtain a thermal insulation window film with excellent comprehensive performance, which perfectly meets In order to meet the market demand, the content of the invention is introduced below

Abstract

The invention provides a wear-resistant thermal-insulation window film and its preparation method and use method. The wear-resistant thermal-insulation window film comprises a wear-resistant layer, asubstrate layer, a thermal-insulation adhesive layer, an ultraviolet absorption layer and a residual-free adhesive layer. The thermal-insulation adhesive layer contains nanometer hollow glass microspheres coated with tin-doped indium oxide. The residual-free adhesive is an acrylic adhesive. The acrylic adhesive is obtained by living radical polymerization and has a polydispersity index of less than 2.5. Through the above composition, the thermal-insulation window film with excellent overall performances is obtained and satisfies many requirements in use.

Description

technical field [0001] The invention relates to the field of heat-insulating window film, in particular to the field of wear-resistant and heat-insulating window film, and also relates to a preparation method and application method of the heat-insulating window film. Background technique [0002] With the development of society, the penetration rate of automobiles is getting higher and higher, and the automobile industry has become a sunrise industry for industrial discovery. Subsequently, the peripheral products of automobiles are also developing rapidly, and the demand for automotive film is increasing year by year. This demand is reflected in the exponential growth of demand on the one hand, and on the other hand, in the improvement of the performance requirements of the protective film. [0003] Under the strong light, the temperature inside the car rises rapidly. In order to solve this problem, automotive insulation films emerge one after another, which can effectively ...
