Crack-resistant thermal insulation mortar and preparation method thereof

Abstract

The invention discloses crack-resistant thermal insulation mortar. The crack-resistant thermal insulation mortar is characterized by being prepared from the following materials in parts by weight: 310-380 parts of cement, 130-160 parts of bentonite, 180-240 parts of phosphorous slag powder, 4-7 parts of acrylate resin, 8-12 parts of methyl cellulose, 120-165 parts of glass beads, 5-8 parts of calcium oxide, 10-12 parts of magnesium oxide, 18-25 parts of creeper roots, 30-40 parts of Japanese banana leaves, 3-5 parts of sodium fluosilicate and 4-7 parts of auxiliaries. The thermal insulation mortar prepared in the invention has the characteristics of being light in volume-weight, low in heat conductivity coefficient, crack-resistant, strong in adhesion stress, excellent in peaceability and construction performance, has the advantages of being waterproof and impervious, and high in compressive strength, and can be widely applied to thermal insulation of interior and exterior walls of a building and other special projects. The crack-resistant thermal insulation mortar disclosed by the invention comprehensively utilizes various waste slag, so that environment is protected, resources are saved, recycling economy effect of changing waste into things of value is realized, product competitiveness is improved, and therefore, the crack-resistant thermal insulation mortar can be popularized and applied.

Description

technical field [0001] The invention relates to the technical field of thermal insulation mortar, in particular to a crack-resistant thermal insulation mortar and a manufacturing method thereof. Background technique [0002] In recent years, various solid wastes produced in industrial production processes and solid wastes brought about by urban construction demolition and reconstruction have been troubled by the living environment of residents. This invention adds solid wastes as raw materials to the thermal insulation mortar to realize the recycling of wastes. Utilization reduces the pollution to the environment and meets the requirements of the sustainable development strategy. [0003] Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed with water by the production enterprise. It can be used not only for external thermal insulation of building exterior ...

AI Technical Summary

Problems solved by technology

However, the existing traditional mortar thermal insulation materials, such as polyfoam particle thermal insulation mortar, pearl thermal insulation mortar, etc., have exposed many defects during use, such as surface hollowing, cracking, falling off, easy to mildew, etc. In addition, large Part of the insulation mortar has high porosity, so the overall water absorption rate is very high. After absorbing water, it will not only reduce the strength of the material, but also greatly reduce its insulation performance.
