Abstract

The invention discloses a light cement and bamboo composite and a manufacturing method thereof. The manufacturing method comprises the following steps of: firstly, mixing and uniformly stirring cement, bamboo and water; then, respectively adding a thickening agent, a foaming agent and a coagulant aid into cement slurry and uniformly stirring, wherein the thickening agent, the foaming agent and the coagulant aid are uniformly mixed with water; and finally, filling a die, foaming, forming, carrying out steam curing and carrying out static culture to obtain the light cement and bamboo composite. Compared with a common cement-bonded board, the light cement and bamboo composite manufactured by the invention is low in density smaller than 0.7g / cm<3>, excellent in physical and mechanical properties, particularly good in impermeability and sound and heat insulation property and capable of adjusting the indoor environment and also has a biomass characteristic; and compared with a synthetic material such as a shaving board taking urea-formaldehyde resin, phenolic resin and the like as an adhesive, the light cement and bamboo composite is free of harmful gas release, environmentally-friendly, fireproof, flame retardant, rich in raw material source, low in raw material cost, simple in production process and capable of realizing improved production on the basis of the design of the traditional aerated concrete production line.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a lightweight cement bamboo composite material and a manufacturing method thereof. Background technique [0002] In recent years, due to the sharp decline of global forest resources, countries around the world have restricted logging and reduced timber production year by year for environmental protection purposes, forcing countries to seek alternatives to timber and scramble to develop non-wood panels. my country is the country with the most abundant bamboo in the world. It develops lightweight cement bamboo composite materials, promotes the sustainable development of the forestry industry, improves the bamboo processing industry chain, and contributes to the production and reform of new building wall materials. [0003] Throughout the research and development of cement particle board at home and abroad, we focus on the density of 1.0 ~ 1.3g / cm 3 , for densities le...
