Abstract

The invention belongs to the technical field of materials, and specifically relates to a sound-insulating coating, which includes the following components: styrene-butadiene rubber, rosin, propyl epoxy resin, ethyl cellulose, polyurethane, desulfurized gypsum and mortar. The invention provides a A sound-insulating material mainly having a sound-insulating effect and a production method thereof.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a sound-insulating coating. Background technique [0002] The main sound-insulating raw material in the sound-insulating coating is a nano-layered structure material, which sandwiches the coating molecular material. The entire interlayer is evenly distributed with sound-insulating particles, which can reduce the transmitted sound wave energy, thereby playing the role of sound-absorbing and sound-insulating. [0003] A heat-insulating and sound-insulating coating (notification number CN104449316B) discloses a heat-insulating and sound-insulating coating, which includes the following components and parts by mass: toluene diisocyanate, glycerin, catalyst, non-ionic chain extender, ionic chain extender, Neutralizer, silane coupling agent, silica powder, carbon fiber, bentonite, dispersant. The sound insulation coating provided by this patent has not very strong sound ...
