Problems solved by technology

[0002] As we all know, the thermal insulation materials used in traditional external wall insulation systems are generally organic materials such as expanded polystyrene or extruded polystyrene, but these materials have exposed more and more problems during long-term use, such as easy Aging and shedding, pollution to the environment, etc., especially several major fire accidents caused by them in recent years, have caused huge losses to people's lives and property. In addition, the strength of expanded polystyrene or extruded polystyrene Low, a slight impact from the outside can cause damage to the wall

Abstract

The invention relates to the field of building materials, in particular to a light environment-friendly foaming cement thermal insulation material. The thermal insulation material is characterized by being made from the following raw materials in parts by weight: 70-90 parts of cement, 30-50 parts of coal ash, 10-20 parts of hollow glass beads, 3-8 parts of foaming agent, 0.4-2 parts of stabilizer, 1-1.5 parts of water reducer, 5-10 parts of aluminum sulfate and 0.1-0.3 part of polystyrene granules. The light environment-friendly foaming cement thermal insulation material has high fire resistance and a good thermal insulation effect, is prevented from falling off and aging easily, and is environment-friendly.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight and environmentally friendly foamed cement insulation material. Background technique [0002] As we all know, the thermal insulation materials used in traditional external wall insulation systems are generally organic materials such as expanded polystyrene or extruded polystyrene, but these materials have exposed more and more problems during long-term use, such as easy Aging and shedding, pollution to the environment, etc., especially several major fire accidents caused by them in recent years, have caused huge losses to people's lives and property. In addition, the strength of expanded polystyrene or extruded polystyrene Low, a slight impact from the outside can cause damage to the wall. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned existing technical deficiencies, and provide a lightweight and envir...
