Modified vitrified micro bubble thermal insulation composite board and preparation method thereof

Abstract

The invention discloses a modified vitrified micro bubble thermal insulation composite board and a preparation method thereof. The composite board sequentially comprises a surface layer, a thermal insulation layer and a bottom layer from top to bottom, the surface layer, the thermal insulation layer and the bottom layer are manufactured through a mold pressing integrated forming process, the surface layer is composed of interface mortar, the thermal insulation layer is composed of a modified vitrified micro bubble composite material, and the bottom layer is composed of bottom mortar. The modified vitrified micro bubble thermal insulation composite board has the advantages that the thermal insulation layer is composed of the modified vitrified micro bubble composite material, so that not only is excellent thermal insulation performance provided, but also the strength is good; the composite board adopts a three-time material distribution and mould pressing integrated forming process, sothat the strength of the formed board body is improved, and the formed modified vitrified micro bubble heat preservation layer still has excellent heat preservation and heat insulation performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a modified vitrified microbead thermal insulation composite board and a preparation method thereof. Background technique [0002] Common inorganic insulation boards on the market include rock wool boards, foamed glass boards, foamed cement boards, foamed ceramic boards, etc. Among them, rock wool boards have relatively good fire resistance, heat preservation and sound absorption properties, and are light in weight, but their existence Easy to absorb water, low strength and other problems, it needs to be combined with silicon-calcium board and other boards to be better used; foamed glass board has disadvantages such as high brittleness, easy cracking, and high cost; foamed cement board has high thermal conductivity, thermal insulation, etc. Poor thermal performance, brittle and easy to crack, etc.; foamed ceramic plates have problems such as high thermal con...
