Novel composite board

Abstract

The invention relates to a novel composite board which comprises a square board body made of a magnesium oxide and magnesium chloride composite material; a convex part for board body connection is formed on one side of the board body; a concave part matched with the convex part is formed on the other opposite side of the board body; a cavity is formed in the middle of the board body and is filledwith a core material made of foaming cement; the core material is of a honeycomb structure; each of the convex part and the concave part is of a ladder-shaped structure. The novel composite board provided by the invention has the benefits that the fire prevention, heat insulation and sound insulation effects are good, and the strength is higher; the core material is not melted in a high-temperature state, cannot cause the hollow destruction, has the strength of 5 times of cement, is high in earthquake resistance strength, is fused and pasted with the cement and other building materials to achieve a degree of integration and is more stable in performance; a certain gap is formed between connected boards to form a guide groove, so that the forces of a wall board are concentrated together, the bending strength, the impact strength and the physical and mechanical properties of the composite board are improved, and the construction, the assembly and the disassembly are easier.

Description

technical field [0001] The invention relates to the field of construction, in particular to a novel composite board. Background technique [0002] Composite board is a new type of building material used for building walls. Most of the building materials on the market are filled with core materials in the middle. The filling material is generally foam material, which has poor stability and short life. The fusion degree of foam material and cement and other wall materials is not high, and it is not fireproof, and the sound insulation and insulation effects are poor, and the strength is not high. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a new type of composite board with good stability, high strength, high degree of integration with wall materials, and good sound and heat insulation effects. [0004] The novel composite plate of the present invention comprises a square plate body made of compo...

Problems solved by technology

[0002] Composite board is a new type of building material used for building walls. At present, most of the building materials on the market are filled with core materials in the middle. The filling material is generally foam material, which has poor stability and short life.

The fusion degree of foam material and cement and other wall materials is not high, and it is not fireproof, and the sound insulation and non-isolation effect is poor, and the strength is not high
