A kind of viscose fiber/diatomite composite thermal insulation mortar and its preparation method

Abstract

The invention discloses viscose / diatomite composite thermal insulation mortar. The viscose / diatomite composite thermal insulation mortar is characterized by being prepared from the following raw materials in parts by weight: 300-340 parts of cement, 200-230 parts of thiourea waste residue, 100-120 parts of silica fume, 200-250 parts of diatomite, 230-240 parts of bauxite, 5-8 parts of cellulose ethers, 150-180 parts of medical stones, 6-9 parts of viscose, 2-6 parts of sodium sulfate, 2-5 parts of sodium methylsilanolate and 3-6 parts of auxiliaries. According to the invention, the thiourea waste residue is added into the raw materials of the thermal insulation mortar, and other normal auxiliaries are added at the same time; the thermal insulation mortar produced by adopting a proper production process has the advantages of being low in cost, good thermal insulation and heat insulation, strong in fireproof and corrosion-resistant performance, high in compressive strength, green, environment-friendly and the like, realizes the recycling economy effect of changing waste into things of value, and has great market space and development prospects in the national building energy-saving application field.

Description

technical field [0001] The invention relates to the technical field of thermal insulation mortar, in particular to a viscose fiber / diatomite 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 of b...

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.
