Problems solved by technology

The disadvantage is that the upper and lower partitions are made of stainless steel, and the thermal bridge effect is serious. Although it can be used in a high temperature environment for a long time, the effect is not good in a low temperature environment, which affects its further application and promotion.
[0007] Although the above-mentioned invention patents all disclose a kind of vacuum insulation panel, the film materials are all made of a single material, which has caused certain limitations to the field of use of the vacuum insulation panel. The present invention aims to study a new type of vacuum insulation panel. By adding inorganic vitrified powder and hollow ceramic microspheres, the fire resistance level and thermal insulation performance of the insulation board are improved, and the application field of the vacuum insulation board is expanded.

Abstract

The invention discloses a novel vacuum insulated panel. The novel vacuum insulated panel comprises a gas barrier layer and a core material, the heat conductivity coefficient is 0.001-0.002 W / m*K, thegas barrier layer is prepared from a plurality of layers of composite thin-film materials, the core material is prepared from hollow ceramic micro-beads, glass fibers, nano silicon dioxide, porcelainpowder, silicon carbide, a gas adsorbent and a drying agent, the porcelain powder is prepared from a low-temperature porcelain powder body, a medium-temperature porcelain powder body and a high-temperature porcelain powder body, the gas adsorbent is one selected from silica gel, aluminum oxide, a molecular sieve and natural clay, and the drying agent is one or more selected from phosphorus pentoxide, anhydrous calcium chloride, soda lime, quick lime, NaOH solid, montmorillonite, magnesium perchlorate and active anhydrous copper sulfate. The prepared novel vacuum insulated panel has the advantages of being relatively high in fireproof performance, relatively low in heat conductivity coefficient, good in corrosion resistance, waterproof, windproof, excellent in mechanical property, long in service life and not liable to combust.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a novel vacuum insulation panel. Background technique [0002] In recent years, energy saving and environmental protection have become the most concerned issues. The traditional organic insulation materials are flammable and corrosive, which limits their wide application in the construction field, while inorganic insulation materials have disadvantages such as poor insulation performance and high density. Big limitations. Therefore, people pay more and more attention to the production and use of thermal insulation materials, especially the research on the thermal insulation performance and sound insulation performance of some new and environmentally friendly interlayer materials is getting deeper and deeper. [0003] Vacuum insulation panel is one of the most advanced high-efficiency insulation materials in the world. It is a kind of vacuum insulati...
