Light heat-insulating cement wall panel

Abstract

A light heat-insulating cement wall panel is characterized by comprising the following raw materials in percentage by weight: 20 to 30 percent of high alumina cement, 20 to 30 percent of ceramic aggregates, 20 to 30 percent of fly ash, 20 to 30 percent of straw fibers or wood fibers, 20 to 30 percent of perhydro foaming agent and 20 to 30 percent of rubber latex cement modifier. The ceramic aggregates are added into the cement as a light aggregate of the cement; steel nets are added in the wall panel; and meanwhile, the straw fibers or wood fibers are added. Therefore, high compressive strength and high bending strength of the wall panel are guaranteed; the wall panel has advantages of light weight, good heat insulation, and much higher indexes than the prior cement IRC board, chlorine-magnesium containing cement light board and plaster light body partition wall board.

Description

technical field [0001] The invention relates to a building component, in particular to a light-weight thermal insulation wall board. Background technique [0002] With the promotion of new energy-saving building materials and technologies in the country, there have been many types of light-weight thermal insulation wallboards in recent years. Wallboards such as reinforced gypsum boards, fly ash boards, and paper grass boards have low strength and poor thermal insulation performance. Body panels also use chemical materials that easily pollute the environment. The wall board with cement as the main material has a contradiction between strength and weight. The strength is high, the proportion of cement is relatively large, and cement and sand account for more than 50%. The weight of the wall board is very heavy. And the sound insulation effect is all bad; In order to reduce weight, add a large amount of lightweight materials such as more than 50% expanded perlite in cement, al...

[0002] With the promotion of new energy-saving building materials and technologies in the country, there have been many types of light-weight thermal insulation wallboards in recent years. Wallboards such as reinforced gypsum boards, fly ash boards, and paper grass boards have low strength and poor thermal insulation performance. The body panels also use chemical materials that are likely to pollute the environment

The wall board with cement as the main material has a contradiction between strength and weight. The strength is high, the proportion of cement is relatively large, and cement and sand account for more than 50%. The weight of the wall board is very heavy. and sound insulation effects are not good; in order to reduce weight, a large amount of light-weight materials such as more than 50% expanded perlite are added to the cement. Although the self-weight is reduced, the strength of the wall board is greatly reduced, which cannot meet the building requirements.
