Problems solved by technology

[0003] Existing external wall thermal insulation systems generally bond VIP thermal insulation panels (also known as vacuum thermal insulation panels) on the surface of the concrete wall after pouring. Although the thermal insulation effect is good; however, the VIP thermal insulation panels are easily damaged during construction, which reduces the thermal insulation performance.
At present, the core material of the VIP insulation board is not resistant to impact, is easy to break, and is easy to separate from the barrier film, and the flame retardancy cannot meet the requirements, which needs to be solved urgently

Abstract

The invention discloses a high strength core material used for VIP thermal insulation boards. The high strength core material comprises, by weight, 5 to 10 parts of phenolic resin, 10 to 20 parts of oxidized starch, 6 to 12 parts of methyl vinyl phenyl polysiloxane rubber, 6 to 12 parts of polyurethane, 35 to 55 parts of straw filament, 10 to 16 parts of corn protein fiber, 25 to 45 parts of asbestos compound, 6 to 18 parts of diatomite, 10 to 20 parts of calcined kaolin, 10 to 20 parts of nanometer bentonite, 5 to 10 parts of active calcium oxide, 2 to 4 parts of an anti-light oxidant, 1 to 3parts of silane coupling agent, 0.4 to 0.9 part of cation polyacrylamide, and 0.6 to 1.2 parts of disodium dihydro dihydroanthracene. The high strength core material used for VIP thermal insulation boards is extremely excellent in compact resistance and mechanical properties; fracture is not easily caused by intensive impact; shrinkage is not easily caused in processing; the thermal insulation performance and the flame resistance are extremely high; and the service life is long.

Description

technical field [0001] The invention relates to the technical field of VIP insulation boards, in particular to a high-strength core material used for VIP insulation boards. Background technique [0002] Building energy conservation is one of the main tasks in implementing national environmental protection and energy conservation policies. At present, in the field of construction, the heat loss of the outer envelope structure is relatively large, and at the same time, the walls of the outer envelope structure account for a large proportion. Therefore, the progress of external wall insulation technology has become an important technology in the field of building energy conservation. [0003] Existing external wall thermal insulation systems generally bond VIP thermal insulation panels (also known as vacuum thermal insulation panels) on the surface of the concrete wall after pouring. Although the thermal insulation effect is good; however, the VIP thermal insulation panels are...
