Description

A rock wool polyurethane composite thermal insulation board external wall thermal insulation structure

technical field

The utility model belongs to external wall thermal insulation materials, in particular to a rock wool polyurethane composite thermal insulation board external wall external thermal insulation structure. the

Background technique

With the continuous advancement of my country's energy-saving policies, more and more attention has been paid to the external thermal insulation of building exterior walls, and the external thermal insulation structure system of external walls has gradually matured. At present, the external wall insulation system commonly used in my country is mainly composed of adhesive layer, insulation layer, connectors, bottom layer, reinforcement layer, surface layer and decorative layer. The insulation layer is mainly made of organic insulation materials such as polyurethane and EPS. Or rock wool, mineral wool and other inorganic insulation materials. These thermal insulation materials either have good thermal insulation performance, but the combustion level is not high, and the fireproof performance is not good; or the fireproof performance can reach Class A, but the thermal insulation performance is not ideal. EPS is one of the most widely used thermal insulation materials since my country has thermal insulation systems. Its construction technology is mature and its thermal insulation effect is good. However, due to the flammability of EPS, after several fires, the Fire Department of the Ministry of Public Security issued a document No. 350, Strict restrictions on the use of flammable and combustible insulation materials such as EPS have been made; the fire performance of inorganic insulation materials such as rock wool can reach Class A, but they are easy to absorb water. After absorbing water, the insulation performance is seriously reduced, and the mechanical properties are also affected accordingly. With the continuous improvement of technical requirements in the field of external thermal insulation of building external walls, the market needs an external thermal insulation structure system of external walls that combines excellent fire resistance performance and good thermal insulation performance. the
