Vacuum self-adsorptive heat insulation and noise reduction reinforced plastic flat plate

Abstract

The invention provides a vacuum self-adsorptive heat insulation and noise reduction reinforced plastic flat plate. One surface of the plastic flat plate is a flat and smooth plane, while the other surface is provided with a plurality of regularly-formed blind holes and coated with a heat reflection metal film; small grooves between the bottoms of adjacent blind holes are communicated with one another; the communicated blind holes can be vacuumized; the plastic flat plate can firmly adsorb on the surface of a smooth and flat glass plate or metal plate under the action of negative pressure; and the conduction of heat and sound waves are blocked effectively by the properties of the material of the plastic flat plate, the heat reflection metal coated film on the surface and the internal vacuum condition. The plastic flat plate has a simple structure, is easy and convenient to install, allows the ordinary person to modify the conventional household doors and windows by using the ordinary tools, saves energy, protects the environment and improves living environment.

Description

Technical field [0001] The invention relates to a flexible flat plastic product, in particular, it has a structure capable of being evacuated into a vacuum and functions of heat insulation and noise reduction. Background technique [0002] At present, the commonly used thermal insulation and noise reduction products on building doors and windows include polystyrene foam noise reduction sheet (EPS board), various thermal insulation films, heat reflective glass, laminated glass, hollow double-layer glass, etc., which are generally not complex in structure. , The cost is high, that is, the cost is relatively high, the effect is not good, and the transformation of a large number of existing old doors and windows appears to be cumbersome and technically complex, which cannot be used by ordinary residents themselves. SUMMARY OF THE INVENTION [0003] In view of such defects and deficiencies, the present invention provides a vacuum self-adsorption type heat insulation and noise r...
