Problems solved by technology

But these materials also have the following problems: 1. Organic thermal insulation materials are flammable, have toxic gases, poor physical and chemical stability, easy aging, short service life, organic thermal insulation materials do not match inorganic wall surfaces, are prone to shrinkage and deformation, and are difficult to construct
Inorganic insulation materials are easy to absorb water, crack and have poor corrosion resistance
The manufacturing process of composite insulation materials is complicated and the manufacturing cost is high

Abstract

The invention provides a composite plate material of foam microcrystalline glass and pure microcrystalline glass. The composite plate material comprises a base body and a decoration surface, wherein the base body is made of a foam microcrystalline glass mixed material; the thickness of the base body is 50mm to 500mm; the decoration surface covers the surface of the base body and is made of pure microcrystalline glass granules; the thickness of the decoration surface is 3mm to 30mm. The invention also provides a manufacturing method of the composite plate material. The composite plate material of the foam microcrystalline glass and the pure microcrystalline glass, provided by the invention, can simultaneously replace a building material and a decoration material, and is small in specific gravity, high in strength, fireproof and corrosion-resistant; environment products which are difficultly handled in a natural environment and industrial wastes which are difficultly treated currently can be consumed; the environment stress is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to a composite plate of foam glass-ceramics and pure glass-ceramics and a manufacturing method thereof. Background technique [0002] At present, the existing glass-ceramic is generally in the form of a solid plate, which is mainly used for interior and exterior wall and floor decoration. It is characterized by corrosion resistance, high temperature resistance, high strength, high gloss, zero water absorption, and strong antifouling ability, and is not easy to Aging, but due to its large specificity and heavy mass, it greatly increases the gravity of the building, which makes the construction difficult and the application range is limited by its own weight. [0003] At present, building insulation materials at home and abroad mainly include organic insulation materials, inorganic insulation materials, and composite insulation materials. Organic insulation materials ma...
