Abstract

The invention relates to a production method of a pressure-resistant impact-resistant thermal insulation building material, and belongs to the technical field of processing of building materials. Theproduction method of the pressure-resistant impact-resistant thermal insulation building material comprises the steps of firstly, crushing and mixing cotton and rice straw, after the cotton and the rice straw are crushed, putting an obtained crushed mixture into alkali liquid, conducting stirring, after stirring is conducted, conducting filtering to obtain an organic solid product, then mixing theorganic solid product and acetic acid, after mixing is conducted, adding aluminium chloride powder, conducting stirring to produce modified mixed liquid, then adding potassium permanganate into the modified mixed liquid for a reaction, conducting reaction arc concentration to produce a concentrated organic product, then adding the concentrated organic product into distilled water for vibration, then adding alkali liquid dropwise to produce alkaline reaction liquid, then conducting filtering and high-temperature treatment on the alkaline reaction liquid to produce a thermal reaction product, finally, mixing and grinding the thermal reaction product, organic silicon resin, gypsum powder, coal ash and another raw material, and conducting drying to obtain the pressure-resistant impact-resistant thermal insulation building material. Bn introducing a fiber component in the cotton, the fiber component and aluminium ions combine to generate aluminium oxide nanoparticles, so that the mechanical strength and the thermal insulation performance of the building material are comprehensively enhanced, so that the building material has wide application prospects.

Description

Technical field [0001] The invention relates to a method for preparing pressure-resistant, impact-resistant and heat-insulating building materials, and belongs to the technical field of building material processing. Background technique [0002] Insulation materials are generally materials whose guiding thermal coefficient is less than or equal to 0.12. The rapid development of thermal insulation materials, the use of good thermal insulation technology and materials in industry and construction can often achieve a multiplier effect with half the effort. [0003] Traditional thermal insulation materials are mainly based on increasing the gas porosity and reducing the thermal conductivity and conductivity. In order to increase convective and radiative heat transfer, fiber insulation materials must have a thicker coating; while profile-type inorganic insulation materials need to be assembled and constructed, which has many joints, detrimental to appearance, and waterproof Defects su...
