Problems solved by technology

[0005] Existing building fiberboards are generally processed by adding bamboo and wood fibers to plastics. The material is heavy and cannot achieve the effect of fire prevention and heat insulation. The use of bamboo and wood fibers requires multiple processes of bamboo and wood materials to be repeatedly refined, and the production cost is high.

Abstract

The invention discloses a cement fiber foam board. The cement fiber foam board is characterized by comprising the following components in parts by weight: 50 to 60 parts of straw fibers, 20 to 25 parts of silicon-aluminum sol, 14 to 18 parts of a binder, 10 to 12 parts of propyl p-hydroxybenzoate, 6 to 10 parts of hydrotalcite, 12 to 15 parts of barium silicate, 10 to 14 parts of perlite powder, 30 to 40 parts of cement, 0.2 to 0.3 part of a water retention agent, 0.3 to 0.5 part of a waterproof agent, 4 to 6 parts of a flocculating agent, 10 to 12 parts of polyvinyl acetate, 1.5 to 2 parts ofcalcium stearate, 0.6 to 1 part of lauryl sodium sulfate, and 30 to 40 parts of water. The straw fibers prepared from crop waste straws are used as a raw material and mixed with cement to be foamed,and the mixture is made into the cement fiber foam board by virtue of a mold, so that the product is energy-saving, environmentally friendly, and low in production cost; the product can prevent fire and insulate the heat, and can meet the building thermal insulation requirement; and the product is light in weight, and convenient to install.

Description

technical field [0001] The invention relates to the technical field of integrated wall panels, in particular to a cement fiber foam board. Background technique [0002] Fiberboard refers to a wood-based panel made of lignocellulosic fibers interwoven and using their inherent adhesive properties. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and has a wide range of uses. [0003] Existing fiberboards are all made of bamboo fiber and wood fiber, and the materials used are wood and bamboo. With the development of society, the country attaches great importance to the environment, and the supply of wood and bamboo continues to decrease, making the cost of fiberboard unsatisfactory. reduce. [0004] Foamed cement is a lightweight porous material made by mixing cement slurry with foam made by chemical foaming process with cement as the main cementitious material. The unique structural properties of ...
