Description

A high-strength composite building board

technical field

The utility model relates to the field of building materials, in particular to a high-strength composite building plate.

Background technique

At present, thermal insulation boards for building walls are mainly made of foam boards or extruded plastic boards. Although these boards can play a role in thermal insulation, they are not fireproof, so the country has restricted their use. With the development of the construction industry, the requirements for fire protection of building insulation boards are getting higher and higher, and the demand is also increasing.

Others directly use rock wool, mineral wool, and glass wool as insulation materials, which have excellent fire resistance and will not be ignited by fire. The fire rating is Class A. However, these materials are easy to delaminate like cotton, and cannot be well integrated with the building. Wet paste or dry hanging technology is used to fix the rock wool board on the building, but because the existing rock wool board itself is tensile, The technical indicators such as shear strength are relatively poor, which makes the wet-laid rock wool external thermal insulation system unstable and potential safety hazards. Especially after the country puts forward new requirements for external thermal insulation and fire prevention, the existing rock wool boards can no longer adapt to today's construction industry. Requirements for rock wool boards. Therefore, prior art should be further improved.
