Description
Technical Field
The invention relates to the field of building decoration materials, in particular to a waterproof sound-absorbing foam filling agent suitable for walls.
Background
The foam filling agent is a building decoration product which is filled in a pressure-resistant aerosol can by components such as polyurethane prepolymer, a foaming agent, a catalyst and the like. It is often used for sealing, plugging and waterproofing between plastic steel or aluminum alloy doors and windows and walls. The foam polyurethane material can be mixed with the water in the wall and the gap thereof to expand and solidify to form foam when being sprayed out. The porous structure of the foam can effectively fill the gap between the wall plates and simultaneously realize the bonding effect between the two wall plates. The cellular structure of the foam also enhances the acoustical effectiveness of the wallboard.
At present, most polyurethane materials still have certain problems in waterproof and fireproof performances, the waterproof and fireproof performances of the foam filler can be effectively enhanced by adopting the expanded perlite, but because the mechanical properties of the expanded perlite are poor, the addition of the expanded perlite leads to the reduction of the viscosity of the polyurethane prepolymer and the reduction of the mechanical strength and toughness of the foamed polyurethane prepolymer, and the use effect of the foam filler is reduced.
