Light fireproof thermal insulating mortar with cement base

Abstract

The invention relates to a cement-based light fireproof heat-preserving mortar, composed of ordinary portland cement, powder coal ashes, expanded perlite, fibrin, and sodium lauryl benzene sulfonate. It can efficiently construct thermal insulating layers on wall surfaces and top surfaces of buildings, thus improving the heat-preserving and -insulating property of buildings, reducing the energy consumption for heating in the northern winter and temperature drop in the southern summer. It has characters of low density, high temperature resistance, incombustibility, good fire resistance, and use safety. It is applied to the construction of thermal insulating layers of walls and roofs of reinforced concrete, concrete, clay brick, metal, etc, and also applied to the construction of thermal insulating layers of bathrooms, basements, refrigeratories, etc.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a cement-based lightweight fireproof and thermal insulation mortar. Background technique [0002] Population explosion, lack of resources and environmental degradation are the main problems facing people at present, which will lead to a significant warming of the global climate. [0003] In the past, due to the weak overall national strength of our country, the design and construction of buildings have always followed the principle of “being simple and simple, satisfying practicability”. Therefore, existing old buildings mostly use solid clay bricks and concrete as enclosure materials (wall and concrete). The top surface), the reason is that they can both bear weight and act as an enclosure material. However, these traditional enclosure materials have poor thermal insulation properties. The northern regions are cold in winter, and heating facilities must be used ...

AI Technical Summary

Problems solved by technology

[0004] Existing thermal insulation materials, such as polystyrene foam, have light weight and good thermal insulation effects, but they are not fireproof and flammable, which affects the safety of users. In addition, they have very high requirements for construction supporting materials; aerated blocks Such materials can only be used during building construction, and cannot be used as renovation materials for old buildings
