Building exterior wall integral solidified organic heat insulation board and preparation method thereof

Abstract

The invention, relating to the technical field of exterior wall organic heat insulation wall and production thereof, particularly discloses a building exterior wall integral solidified organic heat insulation board and a preparation method thereof. The heat insulation board is prepared by using perlite, ordinary portland cement, slaked lime, heavy calcium, sulpho aluminate, zeolite powder, acrylic acid, and water, and carrying out burdening, dry mix, wet mix, diecast, microwave coagulation, depanning and maintenance. Compared with the prior art, the method has the advantages of simple structure, easy obtainment of raw materials, easy preparation; and the heat insulation board has the advantages of small heat conductivity, low water absorption, stable effect of heat insulation, good flame resistance, short production period, and high efficiency. The invention is suitable for large-scale industrial production.

Description

[technical field] [0001] The patent of the present invention relates to the technical field of inorganic thermal insulation wall for exterior wall and its manufacturing technology, and specifically relates to an integrally solidified inorganic thermal insulation panel for exterior wall of a building and a preparation method thereof. [Background technique] [0002] Perlite has excellent thermal insulation properties and a wide range of thermal insulation applications. Its low bulk density (<80kg / m3) and small thermal conductivity (<0.045W / m.k) make it widely used in building thermal insulation projects. application. Due to the light weight and poor adhesion of perlite bulk particles, it is not convenient for on-site construction and use. Therefore, perlite particles are often combined with reinforcing materials such as polystyrene boards, aluminum foil, plastic film or fiber cloth and bonding materials in buildings. Made into various boards to facilitate building const...

AI Technical Summary

Problems solved by technology

Although this kind of insulation board is wrapped with aluminum foil reinforcement layer and glass fiber cloth to increase the strength to a certain extent, the upper and lower layers of the substrate are still made of pure perlite; although the glass fiber wrapped cloth is coated with cement mortar However, it is difficult to control the thickness of the cement mortar coating. If it is too thick, it will easily increase the overall volume and quality of the board. If it is too thin, it will easily cause damage to the cement mortar coating and lose the bonding and adhesion to the glass fiber cloth. The fixation effect will eventually lead to the escape of perlite particles, causing inconvenience in transportation and construction

In addition, the preparation process of this kind of insulation board is still relatively complicated, and the production cycle is long, which is not conducive to rapid industrial production and improvement of production efficiency
