Problems solved by technology

[0003] However, because the existing caulking gypsum does not have fireproof function, although the gypsum board wall generally does not have cracks and flame penetration when a fire occurs, cracks often occur in the gaps between the board seams , and a flame penetration phenomenon occurs

Abstract

The invention discloses an environment-friendly fireproof sealing gypsum, which comprises the following components in percentage by weight: 0.2 to 8 percent of non-metallic mineral fireproof material, 0.1 to 5 percent of modifier, 0.01 to 0.8 percent of water retention thickening agent, 0.01 to 0.2 percent of bonding agent, 0.01 to 0.5 percent of retarder, 0.1 to 2 percent of intensifier, and the balance of construction gypsum. Because the non-metallic mineral fireproof materials such as mica powder or vermiculite and the like are added, and the modifier, the intensifier and the like are also added, the environment-friendly fireproof sealing gypsum can ensure the basic performances of the sealing gypsum and simultaneously has the characteristics of fire resistance, crack resistance, environmental protection, no toxin, no irritation, and the like.

Description

technical field [0001] The invention relates to an environment-friendly fireproof caulking gypsum, in particular a novel environment-friendly fireproof caulking gypsum with the characteristics of fire prevention, anti-cracking, environmental protection, non-toxic, non-irritating and the like. Background technique [0002] Caulk plaster is a material used to fill gaps between floor tiles or plasterboard walls during building construction. Because the gap occupies a small area of ​​the ground or wall, it is generally believed that it is enough to fill the gap with ordinary caulking gypsum that does not have a fireproof function. Even if a fire occurs, the caulking will not have any real effect. . Therefore, the current caulking plaster is still conventional plaster. [0003] However, because the existing caulking gypsum does not have fireproof function, when a fire breaks out, although the gypsum board wall generally does not have cracks, flame penetration, etc., cracks ofte...
