The invention relates to a foamed cement block, which comprises a surface covering layer formed of low-density foamed cement block, glass fiber mesh cloth, high-density foamed cement or cement. The thermal insulation block is coated with high-density foamed cement mortar or cement on the surface of the base core material of the low-density foamed cement block, and then laid with glass fiber mesh cloth, covered with cement or high-density foamed cement mortar again, and then subjected to high pressure After steam curing and natural curing, a high-strength foamed cement block on the surface is formed. One side end surface of the composite section of the block may have a structure with special-shaped fit, so as to facilitate mutual connection. The invention has the advantages of fire prevention, waterproof, heat preservation, high strength, long service life, low cost, simple and fast production and construction, and environmental protection.
Description
Technical field [0001] The invention belongs to the field of construction, and particularly relates to a building insulation material. Background technique [0002] External wall insulation is an important part of housing renovation. Traditional external wall insulation is composed of polymer mortar, fiber mesh cloth, and benzene board materials, and is bonded on site. Due to the different expansion coefficients of cement and benzene board , Under the condition of large temperature difference, it is easy to cause falling off, shorten the service life, and it is not convenient for users to carry out secondary decoration and hanging ornaments. At the same time, the fireproof performance of benzene board is poor. [0003] In recent years, chemically foamed cement blocks have begun to be paid attention to and applied for their fireproof, thermal insulation and reliable performance. However, ordinary chemical foamed cement blocks are made by cutting, which have low strength, easy crack...
