In order to achieve the above object, the utility model provides a railway carriage bathroom imitative reason stone floor, its characterized in that: the floor surface is unsaturated polyester gel coat waterproof layer, is the wearing layer below the unsaturated polyester gel coat waterproof layer, increases the wearability, is the filling layer below the wearing layer for the increase of strength, weight reduction, waterproof layer, wearing layer and filling layer wrap up the apron of round all around as whole, are equipped with the seal coat below the filling layer, and the seal coat is outer along turn-ups parcel apron upwards for improve inner structure compressive strength.

The wear-resistant layer is formed by curing slurry mixed by unsaturated polyester resin, quartz powder, calcium bicarbonate and color paste with the same color of the unsaturated polyester gel coat on the surface, so that the wear resistance of the surface of the product is enhanced, and the surface color is ensured to be unchanged after the wear-resistant layer is used for a long time and is naturally worn.

The filling layer is formed by solidifying slurry which is formed by uniformly mixing unsaturated polyester resin, shale ceramsite, quartz powder and glass beads, the filling layer has a filling structure thickness, the strength required by the product can be achieved only by filling the filling layer to a certain thickness, and meanwhile, the weight of the product is reduced due to the use of various materials in the filling layer.

The bottom surface of the filling layer is flush with the apron, the thickness of the filling layer is controlled by using the apron, and the filling layer and the apron are flush, so that a sealing layer can be conveniently constructed on the basis.

The upper edge of the apron is turned outwards to form a right angle, so that the connection strength of the apron and the bottom flanging is enhanced.

The apron is formed by coating unsaturated polyester resin on glass fiber and curing, and the glass fiber and the resin can reach certain thickness and strength after being cured and molded so as to ensure that the filler of the filling layer can be fixed inside the apron.

The sealing layer wraps the outward turned edge of the apron, the whole filling layer is wrapped in the sealing layer, and the apron is wrapped at the same time, so that the structure of the whole product is stable.

The utility model discloses with the protruding direct forming of product surface antiskid in the product surface, become an organic whole with the floor, avoid droing to at the inside wearing layer that increases in top layer, increase the wearability, prevent to step on for a long time and strike and cause the surface damaged. Unsaturated polyester resin is filled in the product, and light shale ceramsite, quartz powder and glass beads are added, so that a high-strength base layer and a filling effect are achieved, and the design requirements of light weight and high strength are met.

Detailed Description

As shown in figure 1, the final state of each layer after being manufactured is that firstly, a surface layer unsaturated polyester gel coat waterproof layer 1 is coated, after the gel coat waterproof layer is solidified, unsaturated polyester resin is coated on glass fiber to be laminated and pasted to form a circular apron 5 with the height of 45mm, and the upper edge of the apron is outwards turned into a right angle. Then, the composite material slurry stirred in advance is evenly spread on the surface of the die by a plastic scraper, the thickness is controlled to be 4-5mm, and the wear-resistant layer 2 is constructed. The wear-resistant layer is composed of unsaturated polyester resin, quartz powder, calcium bicarbonate and color paste in a mass percentage of 1:1.5:0.2: 0.1. And after the wear-resistant layer is cured, a filling layer 3 is constructed, the main components of the wear-resistant layer are unsaturated polyester resin, shale ceramsite, quartz powder and glass beads, the mixture is uniformly stirred, the mass percentage is 1:1.8:0.3:0.2, a scraper blade is used for blade coating during filling, the final blade coating height is equal to that of a skirt with the height of 45mm, after construction is finished, the unsaturated polyester resin is coated on the glass fibers for spreading and pasting to carry out integral sealing, a sealing layer 4 is constructed, and the sealing layer is wrapped to the flanging position of the skirt 5.
