Sound absorption coating and production method thereof

The invention discloses a sound absorption coating and a production method thereof. The sound absorption coating is prepared from the following raw materials: polyurethane, emulsion, slag wool fiber,water, a composite coupling agent, diatom ooze, expanded perlite, a levelling agent and a defoamer. The sound absorption coating has good sound absorption property; the coating is free of joints, highin decoration performance, excellent in hardness, finish degree, water resistance and cracking resistance, excellent in stability, and high in hardness; the mechanical property of the coating is enhanced; the usage performance of the coating is more excellent; the adhesion and the friction resistance of the coating are improved; the density and the strength of the coating are increased; the condition that the coating is pulverized, cracked and stripped after being constructed is avoided; the coating is non-toxic and harmless, is free of adverse effects on the human body and the environment, is applicable to reverberation control spaces such as theaters, lecture rooms, conference rooms, swimming pools and gymnasiums, is also applicable to sound improvement environments such as restaurants,dining rooms, offices, airport waiting halls, station waiting rooms, ship waiting rooms, shopping malls and exhibition halls, and can be used as a decorative sound absorption material applied to houses, villas, hotels, guesthouses and entertainment venues.

Inner wall coating and production method

The invention discloses an inner wall coating and a production method. The inner wall coating comprises raw materials, namely polyurethane, an emulsion, silk powder, a hemp fiber, a composite couplingagent, sepiolite, water, titanium dioxide, white carbon black, a leveling agent and a defoaming agent. The inner wall coating disclosed by the invention is capable of adsorbing formaldehyde and volatile organic compounds in the air, preventing radiation, preventing inflaming and purifying the air. The inner wall coating is excellent in hardness, smoothness, water resistance and cracking resistance, good in stability and high in hardness, the mechanical properties of the coating are improved, human bodies and the environment are prevented from adverse influence as the raw materials are non-toxic and harmless, formaldehyde is eliminated, the air is purified, the humidity is adjusted, negative oxygen ions are released, fire and inflaming are retarded, a wall surface can be cleaned by self, the adhesion property and the friction resistance of the coating are improved, the density and the strength of the coating are improved, and the coating is prevented from powdering, cracking or peelingafter being used. The inner wall coating is environmental-friendly and pollution-free, low in cost and wide in application range, the inner wall coating is convenient to use, rapid in drying speed, high in construction efficiency and smooth and glory in appearance.
