Mirror-face explosion-proof film

Abstract

The invention relates to a mirror-face explosion-proof film. The mirror-face explosion-proof film comprises a protective layer, a main film layer, a mirror-face layer, a grating layer, a pressure-sensitive adhesive layer and a release film layer, wherein the release film layer is formed through coating mirror-face ink, and the mirror-face ink is prepared from the ingredients: 28% to 35% of acrylicresin, 25% to 33% of butanone, 15% to 20% of butyl acetate, 0.2% to 0.3% of dispersant, 0.2% to 0.3% of heat stabilizer, 4% to 5% of silica sol, 4% to 6% of flaky glass powder and 7% to 9% of polyisocyanate; the grating layer is prepared from polymethyl methacrylate containing 2% to 3% of photochromic agent; and the grating layer is made of a group of parallel-arranged transparent resin streaks.The mirror-face explosion-proof film disclosed by the invention has a relatively good mirror face effect, the explosion-proof effect is superior to that of ordinary explosion-proof films, the gratinglayer can be used for effectively regulating light transmission rate when light intensity changes, and meanwhile, the transparent sense of the explosion-proof film cannot be lowered; and the mirror-face explosion-proof film has the advantages low manufacturing cost, no wireless signal influence, corrosion prevention, durability, good explosion-proof effect and the like.

Description

technical field [0001] The invention belongs to the technical field of membranes, and in particular relates to a mirror explosion-proof membrane. Background technique [0002] Explosion-proof membranes are widely used because they can prevent glass from splashing when the glass cover is broken, especially in the fields of automobiles, photovoltaics, and electronic equipment. [0003] There are many kinds of explosion-proof membranes. Some explosion-proof membranes have a single color, which cannot match the color of the environment and cannot meet the needs of the public; some explosion-proof membranes have weak reflective and light-transmitting properties. Poor transparency, poor weather resistance, insufficient UV protection, poor heat insulation effect, unable to adjust the internal light according to the strength of the external light source, low surface hardness and not wearable, etc. [0004] The anti-explosion film with mirror surface effect that appeared in recent y...

Problems solved by technology

[0003] There are many kinds of explosion-proof membranes. Some explosion-proof membranes have a single color, which cannot match the color of the environment and cannot meet the needs of the public; some explosion-proof membranes have weak reflective and light-transmitting properties. Poor transparency, poor weather resistance, insufficient UV protection, poor heat insulation effect, unable to adjust the internal light according to the strength of the external light source, low surface hardness and not wearable, etc.

[0004] The anti-explosion film with mirror surface effect that has appeared in recent years is very popular in the market. However, metal evaporation or magnetron sputtering is generally used for the mirror layer of the anti-explosion film on the anti-explosion film to form a layer of metal reflective layer on the base material of the anti-explosion film. , the permeability is poor, and because the existence of the metal reflective layer will affect the wireless signal and affect the communication quality in the car
