Metal vacuum warming plate and manufacturing method for same

Abstract

The invention discloses a metal vacuum warming plate. A vacuum cavity is formed by sealed cooperative connection between an upper metal plate and a lower metal plate; a supporting core is disposed in the vacuum cavity; a vacuumizing hole is formed in the cavity wall of the vacuum cavity; metal with melting point ranging from 90 to 350 DEG C or related alloy sealing bars are arranged between sealing sides for the sealed cooperative connection between the upper metal plate and the lower metal plate; and the sealing bars are bonded with the upper metal plate and the lower metal plate and sealed with the same. The metal vacuum warming plate is advantaged by high vacuum degree durableness in bad natural environments, excellent sealing property, strong anti-deformation capabilities, great corrosion and rust resisting performance and long service life as long as buildings; fireproof performance is A-level; the metal vacuum warming plate is integrated functions of warming, decoration and construction; the construction period can be obviously shortened; installation cost can be reduced; various shapes can be formed; special demands for building outer wall surface corners and arcs can be met; and the metal vacuum warming plate is suitable for various building outer wall warming and roof insulation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a metal vacuum insulation board for external wall insulation and a manufacturing method. Background technique [0002] Existing vacuum exterior wall insulation panels mainly include: VIP vacuum insulation panels and lightweight fireproof vacuum insulation panels. VIP vacuum insulation board uses flexible plastic film as the vacuum sealing material, uses silica powder or high-density polyurethane board as the core material, polymer plastic film as the gas barrier film, and coated glass fiber cloth as the outer surface reinforcement material. The heartwood is placed in the gas-barrier film, and the surroundings of the gas-barrier film are glued and sealed in a hot-melt state, and the vacuum port is heat-sealed after vacuuming. Restricted by its material composition and molding process, its existence: the vacuum degree is realized by the plastic film being bonded and sealed around...

AI Technical Summary

Problems solved by technology

Restricted by its material composition and molding process, its existence: the vacuum degree is realized by the plastic film being bonded and sealed around the support of the heartwood, the internal vacuum degree pressure and the wind load, self-weight, temperature deformation stress borne by the outer wall surface , and finally act together on the gas barrier film made of plastic film, it is easy to be glued and degummed around, the edge of the bonded edge bursts, and the gas barrier film bursts, resulting in damage to the board and complete loss of heat preservation function; with the aging of the gas barrier film , under the long-term action of internal and external forces, its service life is only 15-25 years; the cost of materials is high, and all the materials used are high-priced materials; it cannot be formed into special-shaped panels for corners and other parts; it is used as insulation walls, Glazed tiles and cultural stones are not allowed to be pasted, and the wall decoration method is single
