Composite board and manufacturing method thereof

Abstract

The invention discloses a composite board, and relates to the field of building materials. The composite board comprises a plurality of rock wool boards and fiberglass gridding cloth. Each rock wool board is formed by splicing a plurality of rock wool strips, the fiberglass gridding cloth covers the upper sides and the lower sides of the rock wool boards and is bonded on the rock wool boards through slurry coatings, the rock wool strips are perpendicular to the plane where the fiberglass gridding cloth is located, and a gap which is 9-11 mm is reserved between every two adjacent rock wool boards; and the slurry coatings comprise cement, quartz sand, polymer emulsion powder, water-retaining agents, accelerants and water. The invention further discloses a manufacturing method of the thermal insulation board, the thermal insulation board is high in strength and tensile strength, the bonding force of the fiberglass gridding cloth and the rock wool boards is high, heat preservation, thermal insulation and sound absorption are good, and environmental protection and energy conservation are achieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite board and a manufacturing method of the composite board. Background technique [0002] With the development of society and the increase of population density, people have put forward higher requirements for the performance of building materials, especially in northern regions, where the winter is cold and the heat loss of central heating is very large, which not only wastes energy, but also prevents people from enjoying Comfortable room temperature. At present, the construction industry mostly uses polystyrene as insulation material to fill the wall, but this material has poor flame retardancy, and will produce a large amount of toxic gas after burning, which will cause secondary harm to people. It has thermal insulation and fireproof performance, and two constructions are required to meet the requirements of thermal insulation and fireproofing. The construction is ...

AI Technical Summary

Problems solved by technology

[0005] The current thermal insulation board with rock wool structure is often not high in strength, and is prone to delamination and shedding, which not only affects its normal use, causes safety hazards to the wall structure, but also affects its thermal insulation performance. In addition, the existing above-mentioned thermal insulation Due to the unreasonable structural design of the board and the scientific composition of the slurry coating, its adhesion is poor, and its thermal insulation and thermal insulation properties are also reduced.
