Mirror explosion-proof film

Abstract

This case involves a mirror explosion-proof film, which includes from top to bottom: a protective layer, a main film layer, a mirror layer, a grating layer, a pressure-sensitive adhesive layer and a release film layer; the mirror layer is coated with mirror ink, and the mirror ink Including: acrylic resin 28‑35%, methyl ethyl ketone 25‑33%, butyl acetate 15‑20%, dispersant 0.2‑0.3%, heat stabilizer 0.2‑0.3%, silica sol 4‑5%, flake glass powder 4‑6%, polyisocyanate 7‑9%; the grating layer material is polymethyl methacrylate containing 2‑3% photochromic agent; the grating layer is composed of a group of transparent resin stripes arranged in parallel; the mirror explosion-proof film of this case It has a good mirror effect, and the explosion-proof effect is better than ordinary explosion-proof film. The grating layer can effectively adjust the light transmittance when the light intensity changes, and at the same time it will not reduce the transparency of the explosion-proof film. It has low manufacturing cost, It has the advantages of not affecting the wireless signal, anti-corrosion and durability, and good explosion-proof effect.

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
