Diatom sand beads and high-strength, environment-friendly and thermal-insulation mortar containing same

Abstract

The invention relates to diatom sand beads and high-strength, environment-friendly and thermal-insulation mortar containing the same. The diatom sand beads are prepared from second-class and third-class diatomite used as a raw material through four steps including drying, purification, granulation and roasting. The diatom sand beads are light in weight, environment-friendly and high in adsorbability and have the advantages of damp prevention, fire prevention, purification, thermal insulation and the like. The thermal-insulation mortar is prepared from 50%-60% of the diatom sand beads, 10%-20% of diatom powder, 5%-8% of environment-friendly latex powder, 10%-20% of cement, 1% of wood fiber, 2% of cellulose, 0-10% of glass beads and water. The thermal-insulation mortar can replace cement mortar to be directly applied to building wall brick surfaces, when the thermal-insulation mortar is used for an exterior wall, other decoration processes can be performed directly on the thermal-insulation mortar, and when the thermal-insulation mortar is used for an interior wall, the thermal-insulation mortar can well adsorb indoor formaldehyde produced during decoration, is environment-friendly and can purify indoor air; the thermal-insulation mortar has the advantages of being light in weight, low in heat conductivity coefficient, environment-friendly, thermal-insulation, high-temperature-resistant, fireproof, low-temperature-resistant, noise-reducing, damp-proof, mildew-proof, anti-condensation, free of radioactive substances, stable in physical and chemical property and the like.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials for buildings, and in particular relates to diatom sand beads and high-strength environment-friendly thermal insulation mortar containing diatom sand beads that can be directly used on brick walls. The thermal insulation mortar can replace cement mortar and be directly applied to building walls. On the body brick surface, it can play a good thermal insulation effect, and at the same time has the advantages of environmental protection, moisture resistance, air purification, high temperature resistance, fire resistance, aging resistance, long service life and so on. It is integrated with the building wall and has the same life as the main body of the building. It can replace the cement mortar on the wall. Instead of using cement mortar to plaster the surface, the product can be directly replaced. Background technique [0002] Wall thermal insulation material is a new type of wall material...
