Problems solved by technology

However, the existing EPS insulation board still has great defects in flame retardancy, and the stability performance is not optimistic, and it cannot achieve the effect of Class A non-combustibility
In addition, the thermal insulation and decoration integrated panels using EPS thermal insulation panels as the substrate in the prior art often have technical defects such as insufficient strength of the panels, low rigidity, poor crack resistance, and short service life.

Abstract

The invention provides an inorganic composite EPS heat preservation and decoration integrated board sequentially comprising a core material, a protecting layer, a leveling layer, a base coat and a facing layer from inside to outside. The core material is a flame-retardant-type inorganic composition EPS heat preservation base board. The protecting layer is composed of inorganic dry powder crack proof mortar and an alkali resistant fiber mesh cloth. The provided inorganic composition EPS heat preservation and decoration integrated board has the properties of heat preservation and A2 fire protection, is long in service life, has the good decorative effect, particularly reaches the flame-retardant requirement for an outer wall heat preservation board in 'Code for Building Design of Building Fire Protection' (GB50016-2015) and is applicable to heat preservation engineering outside the building outer wall. In addition, the board of the inorganic composition EPS heat preservation and decoration integrated board is high in strength, high in rigidity and good in cracking resistance property, and accordingly inorganic composite EPS heat preservation and decoration integrated board has wide application prospects and good market potential.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to an inorganic composite EPS thermal insulation and decoration integrated board. Background technique [0002] Under the current technical conditions in our country, combustible materials such as polystyrene foam and rigid polyurethane foam are the most widely used in the external thermal insulation system of building exterior walls. The cause of the problem. Traditional XPS and EPS insulation boards not only have a low ignition point and are easy to burn, they can also cause the flame to spread rapidly and produce toxic gases. The fires in many buildings are caused by the use of flammable external thermal insulation polymer materials that cause the flame to spread rapidly to other floors, resulting in The fire was uncontrollable, and the smoke and toxic gas released by the combustion suffocated people in the fire, causing huge property losses and serious casualties. Therefore, po...
