Problems solved by technology

[0002] With the vigorous promotion of wall self-insulation systems, a large number of self-insulation blocks have emerged in the market, including aerated concrete blocks, which have a certain self-insulation effect, but the strength of traditional aerated concrete blocks is low and easy Cracking, high water absorption, so generally can not be directly used for exterior walls, but more for interior wall masonry
It is impossible to obtain high strength at low bulk density, so it is always difficult for aerated concrete products to enter the thermal insulation building material industry

Abstract

The present invention discloses an expanded vitrified micro-bead aerated thermal insulation product, which comprises a self-thermal insulation building block, a roof thermal insulation plate and a sandwich material of a reinforced concrete component, wherein the material composition comprises expanded vitrified micro-beads, cement, lime, gypsum, fly ash or sand, pp fibers, aluminum powder, an admixture and water. According to the present invention, various components are matched according to a certain ratio and are processed into the finished product according to the specific production process, wherein the bulk density of the product is reduced, the thermal insulation performance is substantially increase and the energy saving effect is significant with the vitrified micro-beads and the foaming agent aluminum powder; no waste water, waste gas and waste residue is discharged during the production process, and the large amounts of the fly ash and other waste are used so as to provide characteristics of environmental protection and waste utilization; and the admixture is adopted to modify the component so as to improve the product strength, such that the service life of the products and the service life of the buildings are the same.

Description

technical field [0001] The invention relates to the thermal insulation building material industry, in particular to expanded vitrified microbead gas-filled thermal insulation products. Background technique [0002] With the vigorous promotion of wall self-insulation systems, a large number of self-insulation blocks have emerged in the market, including aerated concrete blocks, which have a certain self-insulation effect, but the strength of traditional aerated concrete blocks is low and easy Cracking, high water absorption, so generally can not be directly used for exterior walls, but more for interior wall masonry. It is impossible to obtain high strength under the condition of low bulk density, so it is always difficult for aerated concrete products to enter the thermal insulation building material industry. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical solution adopted by the present invention is: an expanded vi...
