Elastic plastic floor which is with the functions of moisture proof and sound insulation, and its production method
The present invention provides an elastic plastic layer that is moisture proof and sound insulation and its production method. The elastic plastic layer that is moisture proof and sound insulation comprises a wear resistant layer, a decoration layer, a first backing material layer and a moisture proof and sound insulation layer. The adjacent layers are connected in turn by the order. The present invention provides the floor that is not only with the function of sound insulation, sound absorption, moisture proof, heat preservation, slightly flipping feet, resistance to press, acid and alkali resistance, but also with the positive effect that is low cost, easy molding, good in mechanical properties, and it is also good in laying effect, inflaming retarding, anti-skidding, easily laying, except that, since the wear resistant layer of the floor is coated with the ultraviolet-curable coating, so that it further improves the scratch-resistant property of the floor.
1. A method of making an elastic plastic floor, the method comprises the following steps:
(a) hot-pressing a wear resistant layer, a decoration layer and a first backing material layer, at 110-150° C., under a pressure of 40-90 kg/cm 2 for 20-40 minutes, to form an intermediate product, wherein the decoration layer is between the wear resistant layer and the first backing material layer;
(b) cold-pressing the intermediate product at 15-40° C. and under a pressure of 40-90 kg kg/cm 2 for 10-30 minutes;
(c) compounding the first backing material layer of the intermediate product to a moisture proof and sound insulation layer to produce the elastic plastic floor, wherein the elastic plastic floor is moisture proof and sound insulated, and wherein the moisture proof and sound insulation layer comprises one or more polymers of an expanded ethylene-vinyl acetate copolymer, an expanded polyethylene, a styrene butadiene rubber or a neoprene, and wherein the thickness of the moisture proof and sound insulation layer is 0.1-6 mm; and
wherein the first backing material layer comprises 10-50 wt % organic polymer, and the organic polymer is a mixture of Polyvinylchloride resin and vinyl resin; and
the wear resistant layer has a surface that comprises an ultraviolet-curable coating, and wherein the surface of the wear resistant layer does not touch or abut the decoration layer, and the ultraviolet-curable coating comprises oligomer, monomer and a photoinitiator.
2. The method of claim 1 , wherein the moisture proof and sound insulation layer comprises a glue that compounded the moisture proof and sound insulation layer to the first backing material layer of the intermediate product.
3. The method of claim 1 , wherein the wear resistant layer comprises one or more organic polymer, plasticizer, lubricant, or stabilizer.
4. The elastic plastic floor of claim 1 further comprising a second backing material layer, wherein the moisture proof and sound insulation layer is between the first backing material layer and the second backing material layer.
5. The elastic plastic floor of claim 1 , wherein the wear resistant layer has a thickness of 0.01-3 mm.
6. A method of making an elastic plastic floor, the method comprises the following steps:
(a) compounding a wear resistant layer, a decoration layer, a first backing material layer, a moisture proof and sound insulation layer and a second backing material layer consecutively, at 160-200° C. for 20-80 minutes, to form an intermediate product;
(b) cold-pressing the intermediate product at 20-60° C. for 20-80 minutes;
wherein the elastic plastic floor is moisture proof and sound insulated, and wherein the moisture proof and sound insulation layer comprises one or more of the polymers of an expanded ethylene-vinyl acetate copolymer, an expanded polyethylene, a styrene butadiene rubber, or a neoprene, and wherein the thickness of the moisture proof and sound insulation layer is 0.1-6 mm; and
wherein at least one of the first backing material layer and the second backing material layer comprise 10-50 wt % organic polymer, and the organic polymer can be a mixture of Polyvinylchloride resin and vinyl resin; and
the wear resistant layer has a surface that comprises an ultraviolet-curable coating, wherein the surface of the wear resistant layer does not touch or abut the decoration layer, and the ultraviolet-curable coating comprises oligomer, monomer and a photoinitiator.
7. The method of claim 6 , wherein the wear resistant layer comprises one or more organic polymer, plasticizer, lubricant or stabilizer.
