Inorganic insulating and plastering dry powder mortar

Abstract

The invention relates to inorganic insulating and plastering dry powder mortar. The mortar includes, by weight, 50-97% of an inorganic gel material, 3-45% of lightweight aggregate and 0-5% of an additive. The inorganic gel material includes by-product gypsum or a composite of the by-product gypsum, or a composite of by-product gypsum and natural gypsum, and also includes an auxiliary material (yellow sand or cement or quick lime or slaked lime or fly ash or mineral slag ash or calcium carbonate, and the like) of the inorganic gel material. The lightweight aggregate is expanded perlite or glass microbeads or a mixture of the expanded perlite and the glass microbeads, and waste slag micropowder produced in production processes of the expanded perlite or the glass microbeads. The waste material that is the waste slag micropowder produced in production processes of the expanded perlite or the glass microbeads is adopted as a lightweight filling material of the mortar, thus improving product performance of the mortar, turning waste into things of value and thoroughly overcoming the problem of treatment of waste materials produced in production processes of the expanded perlite or the glass microbeads.

Description

technical field [0001] The present invention relates to two fields of resource comprehensive utilization and building materials industry, and especially relates to the subversive innovation of industrial by-product gypsum reuse and building energy-saving materials and building plastering materials! Background technique [0002] 1. Building energy efficiency [0003] The current wall energy-saving products in my country are mainly based on organic materials. This is because organic materials have small thermal conductivity and good thermal insulation effect. requirements. However, organic materials have the disadvantages of short service life, poor fire resistance, anti-bio-destruction and environmental protection performance, and cannot meet the requirements of high-rise buildings, public buildings, fire protection and long-term use. [0004] At the same time, our country has a vast area, and the climate characteristics are very different. There are cold areas (North China)...

Problems solved by technology

A large amount of idle industrial by-product gypsum occupies land resources, pollutes the water environment, and increases the maintenance cost of production enterprises. It is a major environmental problem that the government urgently needs to solve!
