A kind of aluminum oxide/zinc oxide composite thermal insulation mortar and its preparation method

Abstract

The invention discloses aluminum oxide / aluminum zinc composite heat-preserving mortar. The aluminum oxide / aluminum zinc composite heat-preserving mortar is characterized by being prepared from the following raw materials in parts by weight: 300 to 360 parts of cement, 200 to 240 parts of alunite, 160 to 190 parts of dolomite, 100 to 120 parts of papermaking slag, 80 to 100 parts of beta-hemihydrate gypsum, 6 to 10 parts of redispersible latex powder, 3 to 6 parts of aluminum oxide, 4 to 7 parts of zinc oxide, 5 to 9 parts of charcoal fibers, 2 to 4 parts of calcium lignosulphonate and 4 to 6 parts of additive. The papermaking slag is added into the raw material of the heat-preserving mortar, so that the cost is low, the performance is good, the cycling economic effect for converting waste into treasure can be realized; by adopting the components which are different from the components of the traditional heat-preserving material, the aluminum oxide / aluminum zinc composite heat-preserving mortar is good in heat-preserving effect, heat insulation effect, waterproof effect and flame-retardant effect and simple and rapid to construct.

Description

technical field [0001] The invention relates to the technical field of thermal insulation mortar, in particular to an aluminum oxide / zinc oxide composite 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 o...

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.
