Can foam caulk soundproof?

Foam caulk is a moisture-cured polyurethane adhesive. The cured foam filler The caulking agent has a porous rigid foam structure and is widely used in waterproofing, sealing, and filling in many fields such as electronic engineering, transportation, and building doors and windows. It can also have a sound insulation effect. Then some people may have questions, can foam caulk reallycan soundproof? , Make it todayEditor is here to serve you Explain it.

Foam caulk is soundproofing. This is mainly because foam caulkhas high surface activity,Can effectively reduce the surface tension of liquid, font>And the double electron layer is arranged on the surface of the liquid film and surrounds the air, Bubbles formed, and then composed of individual bubbles to form a foam, Thus achieving the sound insulation effect. Foam caulkIt is a material that can quickly cover all gaps after being sprayed, After the chemical reaction with the air is completed, will become similar to a foam board一Such material, has a certain sound insulation effect.

Commonly usedfoam caulking agentAlkanes and fluorocarbons with low boiling points, Not only has the advantages of high foaming ratio, good foam stability, and low bleeding volume, at the same time, it can also Magnesite cement plays a certain modifying role, Reduce the probability of products returning to brine and frost. Foam caulkhas been widely used in the production of foamed magnesite products such as fireproof boards and lightweight partition boards span>, And in some products (magnesite fireproof door core, etc.) it plays a key role in success or failure.��.
