Plaster structure with high impact sound insulation performance

Abstract

This invention relates to a gypsum structure with high impact sound insulation performance, comprising at least: a gypsum sound insulation layer disposed on the surface of a floor slab, the gypsum sound insulation layer being formed by curing a half-hydrate gypsum mixture, the half-hydrate gypsum mixture being at least mixed with half-hydrate gypsum raw materials, a certain amount of foaming agent and a plurality of elastic aggregates, the foaming agent giving the cured gypsum sound insulation layer a plurality of micropores to block sound transmission, and the elastic aggregates giving the gypsum sound insulation layer elasticity to absorb impact energy, thereby achieving the purpose of effectively isolating high impact sound.

Claims

1. A gypsum structure with high impact sound insulation performance, comprising at least: a gypsum sound insulation layer disposed on the surface of a floor slab, the gypsum sound insulation layer being formed by curing a half-water gypsum mixture; wherein, The hemihydrate gypsum mixture contains at least hemihydrate gypsum raw materials, a certain amount of foaming agent and multiple elastic aggregates. The foaming agent causes the gypsum sound insulation layer to form multiple micropores after curing, which can block sound transmission. The elastic aggregates make the gypsum sound insulation layer elastic and able to absorb impact energy.

2. The gypsum structure with high impact sound insulation performance as described in claim 1, wherein the elastic aggregate is at least one of rubber particles, cork particles, and hollow glass microspheres.

3. The plaster structure with high impact sound insulation performance as described in claim 2, wherein the rubber particles can be made from waste tires.

4. The gypsum structure with high impact sound insulation performance as described in claim 1, wherein the hemihydrate gypsum raw material accounts for 40-60% of the hemihydrate gypsum mixture.

5. The gypsum structure with high impact sound insulation performance as described in claim 1, wherein the elastic aggregate in the hemihydrate gypsum mixture accounts for 10 to 30%.

6. The gypsum structure with high impact sound insulation performance as described in claim 1, wherein the hemihydrate gypsum mixture of the gypsum sound insulation layer is poured onto the surface of the floor slab, and the hemihydrate gypsum mixture forms the elastic gypsum sound insulation layer after curing.

7. The gypsum structure with high impact sound insulation performance as described in claim 1, further comprising a gypsum strength layer disposed on the gypsum sound insulation layer, the gypsum strength layer being formed by curing at least half of the water-soluble gypsum raw material.

8. The gypsum structure with high impact sound insulation performance as described in claim 7, wherein the hemihydrate gypsum material of the gypsum strength layer is poured onto the surface of the gypsum sound insulation layer, and the hemihydrate gypsum material is cured to form the high-strength gypsum strength layer.
