Abstract

The invention relates to the technical field of insulation boards, in particular to a reinforced PU hard polyurethane foaming insulation board. The insulation board comprises insulation board bodies,connecting grooves and connecting strips, wherein the connecting grooves are formed in the top ends of the insulation board bodies, the connecting strips are arranged at the lower ends of the insulation board bodies, inserting strips are arranged on the left sides of the insulation board bodies, inserting grooves are formed in the right ends of the insulation board bodies, and the connecting grooves and the connecting strips between the different insulation board bodies are buckled, so that the insulation board bodies are spliced in the vertical direction, the inserting strips and the inserting grooves between the different insulation board bodies are buckled, therefore the insulation board bodies are spliced in the horizontal direction, according to the reinforced PU hard polyurethane foaming insulation board, the problems that traditional insulation boards are complex to assemble and disassemble and not firm in splicing are mainly solved, and the reinforced PU hard polyurethane foaming insulation board is mainly used for thermal insulation protection of a wall body.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, and more specifically relates to a reinforced PU rigid polyurethane foam thermal insulation board. Background technique [0002] Rigid polyurethane has low thermal conductivity and good thermal performance. And has moisture-proof, waterproof performance. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water. Moreover, rigid polyurethane is fireproof, flame retardant and high temperature resistant. After adding a flame retardant, polyurethane is a kind of flame retardant self-extinguishing material. Its softening point can reach more than 250 degrees Celsius, and it will decompose only at higher temperatures: in addition, polyurethane will burn in its foam when it burns. A carbon deposit forms on the surface, which helps insulate the...
