A mildew-proof and sterilizing thermal insulation mortar and its production method

Abstract

The invention discloses mildew-proof sterilization type thermal insulation mortar which is characterized by being prepared from the following raw materials in parts by weight: 300-350 parts of cement, 100-150 parts of carbide slag, 14-18 parts of waste polystyrene foam plastic particles, 200-260 parts of fly ash, 16-19 parts of carbon black, 6-9 parts of N-hydroxymethyl acrylamide, 3-6 parts of 8-hydroxyquinoline, 5-8 parts of aluminate coupling agent, 3-6 parts of sodium fluosilicate, 2-4 parts of mulberry fiber and 6-9 parts of auxiliaries. The thermal insulation mortar disclosed by the invention has low thermal conductivity coefficient and good antibacterial and mildew-proof functions and avoids crack and hollowing; by applying solid wastes such as carbide slag and the like to the raw materials of the thermal insulation mortar, the energy is saved, the production cost is reduced, and toxin and pollution are avoided.

Description

technical field [0001] The invention relates to the technical field of thermal insulation mortar, in particular to a mold-proof and sterilizing 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...

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.
