Problems solved by technology

[0002] Existing architectural membrane materials usually only have a fire rating of B1, which is still insufficient for public places. The main reason is that although PTFE has high temperature resistance and is non-combustible, because it is a kind of plastic in nature, it is still in the event of a fire. Will release certain combustion heat value and smoke toxicity

Embodiment 1

[0013] Such as figure 1 As shown, a class A fireproof building membrane material includes a glass fiber cloth 1 and a polytetrafluoroethylene layer 2 compounded on the surface of the glass fiber cloth, wherein the polytetrafluoroethylene layer 2 is filled with inorganic fillers, and the inorganic fillers Includes silicone gel and hollow glass spheres. The polytetrafluoroethylene layer 2 includes the following components, in parts by weight, 100 parts of PTFE, 20 parts of inorganic filler, 1.5 parts of Triton X-45, 2 parts of dispersant, 5 parts of pure water, PTFE is Chenguang PTFE, the dispersant is 5027. Due to the addition of inorganic fillers, the amount of PTFE used can be effectively reduced. In order to increase the fire resistance, the effective solid content of the fillers is increased to 30-50%. Therefore, the amount of PTFE used for the same thickness of PTFE coating can be reduced by 60%. .

[0014] In addition, in order to achieve wear resistance during use, th...

Abstract

The invention discloses an A-grade fireproof building membrane material. The A-grade fireproof building membrane material comprises a glass fabric and a polytetrafluoroethylene layer which is compounded on the surface of the glass fabric, wherein the polytetrafluoroethylene layer is filled with inorganic filler. By means of the A-grade fireproof building membrane material, the heat of combustion can be reduced, and less harmful gas is generated during combustion.

Description

Technical field: [0001] The invention relates to the field of construction, in particular to a Class A fireproof architectural membrane. Background technique: [0002] Existing architectural membrane materials usually only have a fire rating of B1, which is still insufficient for public places. The main reason is that although PTFE has high temperature resistance and is non-combustible, because it is a kind of plastic in nature, it is still in the event of a fire. It will release certain combustion calorific value and smoke toxicity. Invention content: [0003] The technical problem to be solved by the present invention is to provide a class A fireproof architectural membrane material that reduces the calorific value of combustion and reduces the generation of harmful gases during combustion. [0004] The technical solution of the present invention is to provide a class A fireproof building membrane, which includes glass fiber cloth and a polytetrafluoroethylene layer com...
