Enhanced-type thermal-insulation rock-wool composite board and manufacturing method thereof

Abstract

The invention discloses an enhanced-type thermal-insulation rock-wool composite board, and relates to the field of building materials. The enhanced-type thermal-insulation rock-wool 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, a plurality of parallelly arranged grooves are further formed in the upper surface and the lower surface of each rock wool board, and a gap which is 5-9 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 composite board, the composite 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 an enhanced thermal insulation rock wool composite board and a manufacturing method of the enhanced thermal insulation rock wool composite board. Background technique [0002] With the development of society and the increase of population density, people have also put forward higher requirements for the performance of building materials, especially in the northern regions, where the winter is cold, and the heat loss of central heating is very large, which not only wastes energy, but also makes people unable to enjoy Comfortable indoor temperature. At present, the construction industry mostly uses polystyrene as insulation material to fill the walls, but this material has poor flame retardancy and will produce a large amount of toxic gas after burning, causing secondary damage to people. The existing building boards generally cannot be used at the same time. It has heat preservation ...

AI Technical Summary

Problems solved by technology

It mainly solves the technical problem that the existing external wall insulation materials do not introduce glass wool materials, and can make full use of glass wool materials. It has good molding, low volume density, low thermal conductivity, thermal insulation, good sound absorption performance, corrosion resistance, and stable chemical properties. and other characteristics, and improve its construction performance when used as an external wall insulation material

[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.
