Rubber powder polystyrene particle external wall insulation system、 abbreviated as rubber powder polystyrene particle external insulation system. The exterior wall insulation system is a structural system installed on the outer side of the exterior wall、 consisting of an interface layer、 a polystyrene particle insulation layer with adhesive powder、 a crack resistant protective layer、 and a decorative layer、 playing a role in insulation、 protection、 and decoration. The overall cost of the polystyrene particle external wall insulation system with adhesive powder is relatively low、 which can meet the requirements of relevant energy-saving standards、 and is particularly suitable for various external wall insulation projects with complex building shapes. It is currently a widely used energy-saving method for building insulation. The basic structure of the adhesive powder polystyrene particle external wall insulation system is composed of a basic wall surface、 an interface layer、 a crack resistant protective layer、 and a decorative layer The project technical requirements for weather resistance shall not show cracking、 hollowing、 or detachment after 80 cycles of high temperature (70 ℃) - water spraying (15 ℃) and 20 cycles of heating (50 ℃) - freezing (-20 ℃). The tensile bonding strength between the crack resistant protective layer and the insulation layer should not be less than 01MPa、 and the failure interface should be located in the insulation layer. Water absorption/(g/㎡) immersion for 1 hour ≤ 1 000C type ordinary type (single mesh) 3J impact qualified impact strengthened type (double mesh) 10J impact qualified T-type wind pressure value not less than the wind load design value of the engineering project. It is resistant to freezing and thawing、 30 cycles in severe cold and cold areas、 and 10 cycles in hot summer and cold winter areas. The surface is free from cracks、 hollowing、 bubbles、 and peeling. The water vapor wet flow density/g/(㎡· h) ≥ 0.85. The inner side of the waterproof sample protective layer is water free、 permeable、 and wear-resistant、 No cracking、 cracking、 or peeling of surface protective layer or damage to the system within 500L seconds. The tensile strength (C-type)/MPa ≥ 0.1 and the damaged part should not be located at the interface of each layer. The bonding strength (T-type)/MPa (on-site sampling) ≥ 0.4. The seismic performance (T-type) is below the seismic intensity level. The brick surface and external insulation system should not be ignited without detachment. After the test、 the thickness of the test piece should not change by more than 10%
