Problems solved by technology

Fireproof materials are materials that play an absolute role in modern fire prevention, and fireproof materials are divided into non-combustible materials and flame-retardant materials.
At present, in fireproof materials, the base material is sprayed multiple times to meet the fireproof requirements, and after each spraying, it is necessary to wait for 4-8 hours before the next spraying, which takes a long time and requires multiple sprayings. It takes a lot of labor and time for workers, which delays the construction period and affects production efficiency

Abstract

The invention relates to a fireproof material taking gypsum as a base material and a construction method thereof, and belongs to the technical field of building materials. The fireproof material taking gypsum as a base material is a two-component system, wherein the component A is prepared from the following materials in parts by weight: 30-80 parts of gypsum, 0-30 parts of polystyrene particles,0-30 parts of vermiculite, 1-15 parts of fiber, 50-100 parts of sodium carbonate, 1-5 parts of graphite, 1-5 parts of alpha-olefin sodium sulfonate, 1-10 parts of gypsum retarder, 1-3 parts of fillerand 1-3 parts of dicalcium silicate; and the component B is modified aluminum hydroxide and accounts for 5-30% of the weight of the component A. By means of the fireproof material, the one-time spraying thickness of a base material can reach 50 mm, and the problem caused by the fact that the thickness requirement is met only when workers conduct spraying on the base material many times is avoided.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fireproof material with gypsum as a base material and a construction method thereof. Background technique [0002] Fireproof materials are widely used in various technical fields such as industry and construction, and their quality directly affects human property safety and personal safety, so the selection of fireproof materials is very important. Fireproof materials are materials that play an absolute role in modern fire prevention. Fireproof materials are divided into non-combustible materials and flame-retardant materials. Non-combustible materials will not burn, and flame-retardant materials can burn, but they have certain flame resistance. At present, in fireproof materials, the base material is sprayed multiple times to meet the fireproof requirements, and after each spraying, it is necessary to wait for 4-8 hours before the next spraying, which takes a long t...
