Heat-resistant insect-proofing polyurethane foam gap filling material

Abstract

The invention discloses a heat-resistant insect-proofing polyurethane foam gap filling material comprising the raw materials: polyurethane, a styrene-acrylic emulsion, acrylic ester, diphenol propane, xylene, microlite, light calcium carbonate, diatomite, lindane, a talcum powder, zeolite, titanium dioxide, a talcum powder, a cellulose powder, magnesium oxide, nano calcium carbonate, a lamellar-structural mica powder, glass fiber, carbon fiber, quick lime, quartz sand, activated carbon, dichlorinated sodium isocyanurate, sodium potassium tartrate, fumaric acid, glutamine, inulin, borneol, acetyl trioctyl citrate, petroleum sodium sulfonate, sodium lauroyl glutamate, silicone oil, styrene, methyl triethoxysilane, a thickening agent, a silane coupling agent and a foaming agent. The heat-resistant insect-proofing polyurethane foam gap filling material has excellent heat resistant performance and insect-proofing performance.

Description

technical field [0001] The invention relates to the field of polyurethane foam materials, in particular to a heat-resistant and insect-proof polyurethane foam caulking material. Background technique [0002] At present, in the process of building construction, it is inevitable that there will be some gaps due to some reasons, which not only affect the appearance, but also may reduce the quality of the building. Therefore, the construction part of the joint filling material is completed in a short period of time by supporting the glue gun or manual nozzle during construction. Forming, foaming, bonding and sealing processes. The strength of the existing joint filling material is generally insufficient. The solidified foam elastomer of polyurethane foam has excellent properties such as thermal expansion and contraction resistance, heat insulation, sound insulation and even flame retardancy. It is widely used in the side seams of building doors and windows, component expansion j...
