Problems solved by technology
The rock wool insulation board has the function of fire prevention, and the combustion grade of the material reaches Class A. At the same time, it also has the characteristics of light weight and heat preservation. However, the rock wool insulation board has low strength, easy to drop powder, and poor integrity, which limits its large-scale application.

Abstract
The invention relates to a rock wool composite heat insulating board enwrapped by multiple layers of fibreglass gridding cloth and a manufacture method thereof, which are characterized in that the rock wool composite heat insulating board comprises an upper-layer fibreglass gridding cloth and a lower-layer fibreglass gridding cloth; and a layer of low-intensity heat insulating rock wool board is arranged between the two layers of fibreglass gridding cloth which is dipped with mucilage. The rock wool composite heat insulating board enwrapped by the fibreglass gridding cloth and the manufacturemethod have the advantages of simple structural design, fire prevention and better heat insulating effect and can be extensively applied to the external wall heat insulation of various buildings.
Description
technical field [0001] The invention relates to a thermal insulation board, more specifically to a rock wool composite thermal insulation board coated with glass fiber mesh cloth, and also relates to a preparation method of the thermal insulation board. Background technique [0002] The advent of the energy crisis and the implementation of building energy-saving policies have promoted the rapid development of wall insulation materials. At present, the external wall enclosure structure of buildings mostly adopts the external wall external insulation board system with polystyrene foam, polyurethane stearic foam and other organic foam plastics as thermal insulation materials. However, this type of thermal insulation material is extremely flammable. The fire spread rapidly, accompanied by a large amount of poisonous gas and smoke, which brought serious difficulties to fire fighting and rescue work, and easily caused casualties and property losses. At the same time, this type of...
