Abstract

The invention discloses an explosion-proof heat-insulation film with functions of demisting and defrosting. The explosion-proof heat-insulation film comprises a release layer, a pressure-sensitive adhesive layer, an ultraviolet-proof layer, a heat insulation layer, a flexible substrate, a heating layer and an abrasion resistant layer which are sequentially arranged from bottom to top, wherein the outer edge of the heating layer is connected with an electrode. The film is integrated with functions of an existing explosion-proof heat-insulation film and a demisting and defrosting system, so that the functions of preventing explosion, insulating heat, demisting and defrosting can be achieved by pasting only one film by a user, and the film is relatively convenient to use.

Description

technical field [0001] The invention relates to an explosion-proof heat-insulating film and a preparation method thereof. Background technique [0002] At present, there are mainly the following ways to defog and defrost the windshield of the car: [0003] 1) Print the silver paste resistance wire on the glass, and the resistance wire can heat the glass after electrification to realize the function of defogging and defrosting. Because the silver paste lines are opaque, the printed silver paste cannot cover the entire glass, but can only be printed in strips, which leads to uneven heating, glass is easy to break, and it is also impossible to uniformly defog and defrost. Due to the opacity, the silver paste lines It can't be used on the front windshield either. The silver paste is easily oxidized and cannot be heated. [0004] 2) Air conditioning defogging and defrosting system. The defogging and defrosting functions are realized by blowing warm or cold air on the windshiel...
