Basalt fiber gridding cloth wrapped rock wool composite heat-preserving plate and manufacturing method thereof

Abstract

The invention discloses a basalt fiber gridding cloth wrapped rock wool composite heat-preserving plate and a manufacturing method thereof. The basalt fiber gridding cloth wrapped rock wool composite heat-preserving plate comprises a heat-preserving plate and gridding clothes which wrap the upper and lower surfaces and left and right surfaces of the heat-preserving plate, wherein the heat-preserving plate is formed by splicing a plurality of vertical cotton strips; the fiber direction of each vertical cotton strip is vertical to the upper and lower surfaces of the heat-preserving plate; a PVC (polyvinyl chloride) protecting corner wraps each of the four corner angles of the heat-preserving plate; a row of toothed openings corresponding to gridding cloth meshes in the gridding clothes is formed in the PVC protecting corner on one corner angle of the heat-preserving plate; the gridding clothes are basalt fiber gridding clothes; one end of each basalt fiber gridding cloth is hung to the toothed openings through the gridding cloth meshes; after wrapping around the heat-preserving plate for one circle, the other end of each basalt fiber gridding cloth is also hung to the toothed openings through the gridding cloth meshes. The four surfaces of the heat-preserving plate formed by splicing the vertical cotton strip are wrapped by the basalt fiber gridding clothes, and a hydrophobic bonding adhesive cement is coated on the upper and lower surfaces of the heat-preserving plate, so that the whole tensile strength of the rock wool composite plate is effectively improved.

Description

technical field [0001] The invention relates to a thermal insulation and fireproof board and a production and preparation method thereof, in particular to a rock wool composite board and a production and preparation method thereof. Background technique [0002] The existing rock wool composite boards are mostly made of glass fiber mesh cloth covering the rock wool board. The glass fiber is referred to as glass fiber, which has extremely high tensile strength. The finer the fiber, the higher the strength. ~ 11.5) μm, weft (11.5 ~ 12.5) μm. [0003] Glass fiber mesh is divided into non-alkali, medium alkali and alkali-resistant glass fiber mesh. The content of metal oxides in non-alkali glass fiber mesh is the smallest, followed by medium-alkali glass fiber mesh, and alkali-resistant glass fiber. The metal oxide in the mesh cloth is the most (about 14.5% zirconia and 6% titanium dioxide, the content of zirconia is an important technical index affecting the alkali resistance o...
