Description
Technical Field
The utility model relates to a fire prevention specifically is kind is used for compound fire prevention core board of fire prevention .
Background
The fire prevention refers to 0 which can meet the requirements of fire resistance stability, integrity and heat insulation within time, it is a fire-proof partition which is arranged in fire-proof subareas, evacuation staircases, vertical shafts and the like and has 1 fixed fire resistance, the fire prevention has the functions of preventing fire spread and smoke diffusion besides the function of common , and can prevent fire spread within time to ensure personnel evacuation, the fire prevention core board is the main component of the fire prevention , the fire prevention core board plays a role of heat insulation, the traditional fire prevention core adopts rock wool, glass wool, mineral wool and the like as filling materials, and has the defects of poor strength, substandard fire resistance grade, troublesome construction, and the release of toxic gases such as formaldehyde, carbon oxide and the like during fire occurrence.
Chinese patent CN107269178A discloses low-carbon heat-insulation type composite fireproof core boards, which adopt phenolic foam boards, the working temperature of the phenolic foam boards is-196 to +200 ℃, the phenolic foam boards can burn under the high temperature state of 800-.
Chinese patent CN206397385U discloses kinds of fireproof core boards, which adopt a flame-retardant solid wood skeleton, and the flame-retardant solid wood skeleton is not resistant to high temperature and can burn at high temperature.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide non-combustible, high-strength, nontoxic compound fire prevention core boards.
The utility model provides a technical scheme that its technical problem adopted is:
composite fireproof core boards are of a multilayer structure, the multilayer structure comprises a front glass magnesium board and a back glass magnesium board, the front glass magnesium board and the back glass magnesium board are arranged in parallel, a perlite board is arranged between the front glass magnesium board and the back glass magnesium board, the width of the perlite board is smaller than that of the front glass magnesium board and the back glass magnesium board, a plurality of layers of superposed reinforcing boards are respectively arranged at two vertical side end faces of the perlite board, the board faces of the plurality of layers of superposed reinforcing boards are tightly attached to the two vertical side end faces of the perlite board and are perpendicular to the board faces of the front glass magnesium board and the back glass magnesium board, the width of the perlite board and the thickness of the plurality of layers of superposed reinforcing boards at two sides of the perlite board are equal to the width of the front glass magnesium board and the width of the back glass magnesium board, and the reinforcing boards are.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:
the anti-bending strength of the core board is improved by adding the multilayer overlapped reinforcing plates, the reinforcing plates can effectively prevent the core board from bending deformation when the core board is subjected to high temperature, all components of the core board are zero-volatilization, zero-pollution, non-combustion, heat-insulation and non-corrosive boards, and the core board is long in service life and low in cost.
Step , the optimization scheme of the utility model is that:
