Abstract

The invention relates to the technical field of fireproof building materials, and particularly discloses aluminum silicate high-temperature-resistant cotton for a fireproof coiled material and a preparation method thereof. The preparation method of the aluminum silicate high-temperature-resistant cotton for the fireproof coiled material comprises the following steps: mixing aluminum oxide, silicapowder and graphene nanoplatelets, melting, and blowing to form flocculent fibers; taking the blown flocculent fibers, adding an inorganic binding agent, an organic binding agent and an additive, andperforming mixed pulping to obtain pulp; producing a clothing blank by using a mechanical kneading forming method or a handicraft forming method; and treating the clothing blank at the temperature of100-150 DEG C to obtain the aluminum silicate high-temperature-resistant cotton for the fireproof coiled material. The aluminum silicate high-temperature-resistant cotton prepared by the method not only has fireproof performance, but also has good flexibility; the fireproof coiled material prepared from the aluminum silicate high-temperature-resistant cotton is good in flexibility, fireproof building materials of various structures can be coated in an omnibearing mode, and the excellent fireproof effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of fireproof building materials, in particular to an aluminum silicate high temperature resistant cotton for fireproof coils and a preparation method thereof. Background technique [0002] Fireproof materials are materials that prevent or retard the spread of flames. Commonly used fireproof materials include fireproof boards, fireproof doors, fireproof glass, and fireproof coatings. For example, the steel structure generally adopts the form of steel structure fireproof coating for fire prevention, and the smoke prevention and exhaust duct adopts the form of fireproof board coating for fire prevention. However, the water resistance and construction characteristics of fire retardant coatings lead to large pollution and slow construction speed. The calcium-silicon board used in the smoke prevention and exhaust duct is covered with gaps, and its weight is heavy, there is a lot of waste, and the construction pe...
