Inorganic foam material for joint sealing of wall thermal insulation system and preparation method of inorganic foam material

Abstract

The invention relates to an inorganic foam material for joint sealing of a wall thermal insulation system and a preparation method of the inorganic foam material, and belongs to the technical fields of an inorganic foam material and a preparation method thereof. The inorganic foam material for joint sealing of the wall thermal insulation system consists of the following components in parts by weight: 1 part of foam and 1-20 parts of polymer modified cement slurry, wherein the foam includes 1 part of a foaming agent and 10-100 parts of water; and the slurry includes 500-900 parts of cement, 100-500 parts of a filling material, 10-100 parts of high-molecular polymer, 1-30 parts of a fiber material, 1-30 parts of a water holding thickening agent, 10-100 parts of a water reducing agent, 1-10 parts of a water repellent and 400-1000 parts of water. The preparation method comprises the following steps of: 1) preparing the foam; 2) preparing polymer modified cement slurry; and 3) completely and uniformly mixing the foam and the slurry, and sealing the joint on the wall. The inorganic foam material, which contains a great amount of sealed bubbles, is low in conductivity coefficient; and the inorganic foam material is an inorganic incombustible material, which acts as a fire barrier after sealing the joint on the wall, so that the integral fireproof performance of the wall thermal insulation system is improved, and the application prospect is wide.

Problems solved by technology

[0003] At present, the country has higher and higher requirements for the fire performance of the wall insulation system, but some parts of the wall insulation system, such as the joints between the insulation and decorative panels, expansion joints, settlement joints, curtain wall isolation belts, etc. If the grid joints and isolation belts are not properly handled, there will be a greater safety hazard in terms of fire prevention

At present, most of the caulking materials used in the wall insulation system are polyethylene foam strips, and some are filled with polyurethane foam first and then filled with foam strips. Both foam strips and polyurethane foam are organic materials, and there are fatal problems. Disadvantages: flammable, poor fireproof performance, which directly affects the overall fireproof performance of the wall insulation system, especially in the thermal insulation and decoration integrated system with a large number of divisions in the wall insulation, this fire safety hazard is even more serious serious

Commonly used inorganic caulking materials, such as tile caulking agent, pointing agent, etc., are inorganic non-combustible materials, but their thermal conductivity is too high, and they are rigid bodies without flexibility, which cannot meet the requirements of caulking materials in wall insulation systems. requirements for use
