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...
