Problems solved by technology

[0003] In addition, with the general improvement of rural living standards, straw is no longer used as a living fuel in rural areas, but has gradually become a redundant by-product after grain harvesting. The annual production of crop straw in my country is about 650 million tons, and 20% of the straw has not been obtained. use efficiently

Abstract

The invention discloses an environment-friendly wall fireproof heat-preserving board and a preparation method thereof. The environment-friendly wall fireproof heat-preserving board is prepared from the following raw materials in parts by weight: 26-60 parts of straw powder, 0.2-3 parts of guanylurea phosphate, 0.1-1.2 parts of boric acid, 15-45 parts of magnesium oxide, 5-15 parts of magnesium chloride or magnesium sulfate, 1-30 parts of coal ash or diatomite in powder, 0-30 parts of crushed crude pearlite or leech powder, 0.1-0.5 part of a styrene-acrylic emulsion, 0.1-0.5 part of calcium lignosulphonate and 5-25 parts of tap water. The preparation method comprises the following steps: first, mixing straw powder, guanylurea phosphate, boric acid, magnesium oxide, coal ash or the diatomite in powder, crushed crude pearlite or leech powder and calcium lignosulphonate; then, adding magnesium chloride or magnesium sulfate, the styrene-acrylic emulsion and tap water; and after fully and uniformly stirring at normal temperature, putting in a template, rolling, maintaining and demoulding to prepare the wall fireproof heat-preserving board. The environment-friendly wall fireproof heat-preserving board has the characteristics of high compression and breaking strength, good moisture absorption, water adsorption, flame retardant and anti-freezing performances, small heat conductivity coefficient, no formaldehyde, environmental friendliness, fireproofness and heat preservation.

Description

technical field [0001] The invention relates to an environment-friendly fireproof and heat preservation board for walls and a preparation method thereof, belonging to the technical field of fireproof and heat preservation of building walls. Background technique [0002] In recent years, the occurrence of many building insulation fire incidents has aroused the thinking of all walks of life on thermal insulation and fire prevention. However, many fires of insulation materials are caused during the construction process, such as: electric welding, open flames, and bad construction habits. During the burning process of these materials, the molten droplets and toxic smoke are continuously produced, and the harm to the environment of the released gases such as chlorofluorocarbons, hydrofluorocarbons, and freons cannot be ignored. For this reason, the Ministry of Housing and Urban-Rural Development and the Ministry of Public Security jointly issued the "Interim Provisions on Fire P...
