Biological environment-friendly walling material and preparation method thereof

Abstract

The invention relates to a biological environment-friendly walling material and a preparation method thereof. The walling material comprises the following raw materials in parts by weight: 80-120 parts of main material, 16-24 parts of adhesive and 24-36 parts of water, wherein the main material comprises cement, fine sand, straws and / or couch grass in a mass ratio of (16-24):(8-12):(56-84).The preparation method comprises the following steps: crushing couch grass and / or straws, cutting, and baking to obtain a fiber material; proportionally mixing and blending cement, fine sand, adhesive and water to obtain slurry; uniformly stirring the fiber material and the slurry, and then performing compression molding to obtain a wall blank; and performing natural curing or steam curing on the wall blank until the wall blank is finally set, and cutting to obtain the finished product. The biological environment-friendly walling material provided by the invention is light in weight, has favorable warm keeping / heat insulation / sound insulation properties, achieves a flame retardant effect, and can reduce the weight of a building; and meanwhile, by using the biological environment-friendly walling material, the forest fire hidden danger caused by burning of couch grass and / or straws and resulting air pollution is reduced, and the damage to environmental resources due to massive use of yellow sand is decreased.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a bio-environmental protection wall material and a preparation method thereof. Background technique [0002] At present, my country is in the "double peak" period of urban housing construction and new rural construction, and it is also a critical period for my country's energy conservation, emission reduction and human advocacy of environmental protection. The new environmental protection wall material and its production technology have a wide market demand and development prospect in the society. In the prior art, the wall construction materials are mainly clay solid bricks, cement hollow blocks and concrete aerated blocks. The raw materials of these wall materials, such as clay and yellow sand, are non-renewable resources, and a large amount of clay and yellow sand does not meet the requirements. The requirements of the era of energy saving and environme...

Problems solved by technology

In the prior art, wall construction materials are mainly clay solid bricks, cement hollow blocks and concrete aerated blocks. The raw materials of these wall materials, such as clay and yellow sand, are non-renewable resources, and a large amount of clay and yellow sand does not meet the requirements. The requirements of the era of energy saving and environmental protection, and the clay solid bricks and cement hollow blocks are large and heavy, have poor thermal insulation, heat insulation, and sound insulation effects, and the construction is inconvenient. Cracks often appear on the wall and affect the quality and use of the building. Performance; the raw materials and process requirements for the manufacture of concrete aerated blocks are high, the production cost is high, and it cannot protect the environment and save resources
