Polyurethane-rock wool composite heat insulating plate external wall external heat insulating system with rib laths

Abstract

The invention provides a polyurethane-rock wool composite heat insulating plate external wall external heat insulating system with rib laths. The system comprises a polyurethane-rock wool composite heat insulating plate, an anti-cracking mortar layer of a composite reinforcing net, elastic first coat and a facing layer. The polyurethane-rock wool composite heat insulating plate comprises a rock wool inner core formed by arranging multiple vertical silk rock wool strips into a flat plate shape. Hard foam polyurethane parts I formed in the manner that after polyurethane composite materials are poured on corresponding surfaces of the rock wool inner core, foam forming and curing are completed under pressure are arranged on the inner surface and the outer surface of the rock wool inner core, the hard foam polyurethane part I on each side comprises a hard foam polyurethane layer I covering the corresponding surface of the rock wool inner core, and a polyurethane bonding body I formed by permeating into the rock wool inner core, an aerogel heat insulating mortar layer is formed on the hard foam polyurethane layer I on each side, one rib lath is arranged in the aerogel heat insulating mortar layer on each side, or one rib lath is arranged at the position of a joint interface of the aerogel heat insulating mortar layer on each side and the corresponding hard foam polyurethane layer I.

Description

technical field [0001] The invention belongs to the technical field of building energy saving, specifically relates to the technical field of building thermal insulation building materials, and more specifically relates to an external wall thermal insulation system of polyurethane rock wool composite thermal insulation board with ribbed expansion net. Background technique [0002] With the rapid economic development today, our demand for energy is increasing day by day. But the phenomenon of low energy utilization rate and energy waste is very serious. As a major part of the total energy consumption of the society, building energy consumption accounts for about one-third of the total energy consumption of the society. Therefore, improving the energy-saving level of buildings is very important for improving energy utilization and saving energy. In building energy conservation, the thermal insulation of the outer envelope plays an important role in reducing building energy c...

Problems solved by technology

In order to improve the tensile strength of the rock wool board, a more complicated design structure is adopted in the prior art, but the structure of the rock wool itself is not changed, it is still a loose structure, and the problem that the rock wool is easy to absorb water and deliquescence is not solved. Still can not meet the performance requirements of the rock wool insulation system,

[0022] Throughout the development history of rock wool as an insulation material, from the initial simple horizontal thread rock wool to vertical thread rock wool, from the initial simple rock wool board to reinforced composite rock wool board, but none of them changed the rock wool itself. The structure does not fundamentally solve the defects of rock wool's mechanical properties and water absorption properties at the same time, resulting in the current application of rock wool as building insulation materials is very limited, especially when the requirements for seismic fortification intensity are high and the building height is high. Rock wool board is not applicable
