A kind of ceramic tile waste slag particle insulation mortar and its preparation method

Abstract

The invention discloses thermal mortar of ceramic tile slag particles. The thermal mortar is characterized by being prepared from the following raw materials in parts by weight: 290-330 parts of cement, 200-245 parts of ceramic tile slag particles, 35-50 parts of calcium sulfate whiskers, 85-105 parts of mica, 90-110 parts of aluminum nitride powder, 105-130 parts of kaoline, 75-90 parts of reed stems, 9-13 parts of naphthalene-based superplasticizer, 8-12 parts of sodium tripolyphosphate, 6-9 parts of calcium saccharate and 3-6 parts of assistants. The thermal mortar is light in unit weight, excellent in corrosion resistance, good in heat preservation and sound insulation performances, low in heat conductivity coefficient, and good in water-retaining property, and the product is stable in physical property, free of cracking, free of hollowing, good in ageing resistance and long in service life. The product can be applied by adding water, and is convenient to use, civilized construction can be achieved, and the product is free of toxicity, free of taste, free of harm to a human body, and free of environmental pollution, and belongs to the environment-friendly insulating and energy-saving material.

Description

technical field [0001] The invention relates to the technical field of thermal insulation mortar, in particular to a ceramic tile waste slag granular 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 bu...

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.
