High-strength fireproof composite rock wool board

Abstract

The invention relates to the technical field of engineering materials, in particular to a high-strength fireproof composite rock wool board. The board comprises an upper rock wool board layer, a lowerrock wool board layer and a metal mesh frame layer; the metal mesh frame layer is arranged between the upper rock wool layer and the lower rock wool layer and comprises a mesh frame formed by combining metal strips and fireproof materials filling the mesh frame, and the bottom surface of the upper rock wool board layer and the top surface of the lower rock wool board layer are provided with lugs;auxiliary rock wool board frames are arranged between the metal mesh frame layer and the upper and lower rock wool board layer. The high-strength fireproof composite rock wool board has the advantages that a single rock wool board structure in the prior art is changed, a composite layer form and a multi-layer form are adopted, the strength of the rock wool board is improved, each layer has a goodfireproof and heat preservation effect, and the overall fire resistance is improved; through the arrangement of insertion rods and insertion holes, combination and splicing of the composite rock woolboard are facilitated, the national requirements for the popularization of combined structures are met, and the rapid formation of an entire firewall body is facilitated.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to a high-strength fireproof composite rock wool board. Background technique [0002] At present, bare rock wool boards are mostly used as insulation materials for building curtain walls in the market. Rock wool is made of fiber materials. The strength of simple rock wool boards is generally low, and the fire prevention effect is not good; now the combined structure is being promoted in urban construction. , such as walls, floors, etc., there are few such combined rock wool boards on the market at present. Contents of the invention [0003] In order to solve the above problems in the prior art, the present invention provides a high-strength fireproof composite rock wool board, which can improve the above deficiencies. [0004] The invention relates to a high-strength fireproof composite rock wool board, comprising an upper rock wool board layer, a lower rock wool bo...
