Summary of the application
As described in the background, the existing floor has a planar structure at the edge portion, which results in poor appearance after the whole floor is spliced.
In view of the above technical problems, the technical solution provided by the present application has the following general idea:
the floor with the slope is an oil pressure LVT floor, the edge of the floor close to the floor is in a slope shape, and the thickness of the floor at the edge of the floor shows a trend that the thickness of the floor becomes thinner gradually from the center to the edge. The slope at the edge of the floor enables the floor to be in a concave-convex mode at the joint after being spliced, and enables the floor to be good in overall presenting effect.
Having thus described the general principles of the present application, various non-limiting embodiments thereof will now be described in detail with reference to the accompanying drawings.
The entire floor panel obtained by the oil pressure manner has a size width of 1000mm and a length of 1372.28mm, and is divided into 5 individual sheet-shaped floor panels by cutting in a length direction.
As shown in fig. 1 and 2, wherein fig. 1 is a cross section perpendicular to the longitudinal direction of the floor panel, and fig. 2 is a cross section parallel to the longitudinal direction of the floor panel.
Specifically, taking fig. 1 as an example, fig. 1 has a plurality of first floor modules 1 and second floor modules 4, and the first floor modules 1 and the second floor modules 4 are arranged at intervals. The first floor module 1 is a main body part of a single floor, the second floor module 4 is a lock catch part of each floor after being cut, and the cutting position is the middle position of the second floor module, namely the position of a cutting point in the drawing, so that the second floor module is divided into 2 parts to respectively form a complete sheet floor together with the connected first floor modules.
The first floor module width is the standard monolithic floor width, and the second floor module width is the width for monolithic floor concatenation. As shown in the figure, the width of the bottom surface of the first floor module is 182mm, the width of the surface is 181mm, the width of the bottom surface of the second floor module is 10mm, the width of the surface is 9mm, and the joints of the first floor module and the second floor module at the surface are provided with 1 mm.
The joints of the first and second floor modules are slope-shaped, and the thickness of the floor board at the edges of the floor board in each of the first and second floor modules is gradually thinner from the center to the edges. As shown in the figure, the two sides of the first floor module are provided with first slopes, the two sides of the second floor module are provided with second slopes, the slope surfaces of the first slopes and the second slopes are gradually reduced from the center to the edge of the floor module where the first slopes and the adjacent second slopes are located, and therefore the connecting seam where the first slopes and the adjacent second slopes are connected is the position where the thickness of the whole sheet of plate is the thinnest.
Specifically, in order to take account of the concave-convex effect of the slope and the integrity of the floor, the slope of the floor cannot be too large or too small. As shown in the figure, the width of the slope at the edge of the floor is 6.8-7 mm, and the depth of the slope is 1-1.3 mm. In a specific embodiment of the invention, a ramp width of 6.92mm and a ramp depth of 1.2mm are recommended.
More in detail, the joint of the upper surface of the first floor module and the slope is in fillet transition, and the seam is also designed to be in fillet transition, so that the whole plate is convenient to demould and is not easy to break.
The floor with the modeling needs to be manufactured by matching the following floor raw materials and an oil pressure process.
Specifically, the floor comprises an upper layer structure, a middle layer structure and a lower layer structure, wherein each layer structure comprises main materials of polyvinyl chloride and calcium carbonate, the mass ratio of the polyvinyl chloride to the calcium carbonate in the upper layer structure is 1: 2.5-2.8, the mass ratio of the polyvinyl chloride to the calcium carbonate in the middle layer structure is 1: 3.2-3.6, and the mass ratio of the polyvinyl chloride to the calcium carbonate in the lower layer structure is 1: 1.2-1.5.
In the above-described embodiments, since the surface of the finally-manufactured floor, particularly the edge, needs to be curved, a material having excellent internal filling performance and a material having high surface adhesion strength are required, and the material of the lower layer needs to have sufficient hardness to support the middle layer and the upper layer. Therefore, a relatively soft middle layer material is needed to enable the surface of the floor to be bent without breaking, and the middle layer material and the upper layer material with high fitting strength are matched to enable the surface texture to be clear and not easy to warp. The invention realizes different performances of each layer by adjusting the main material ratio of the upper layer, the middle layer and the lower layer. In addition, the continuous height fluctuation appears on the whole width of the floor, and the air bubbles are easily generated at the fluctuation position during the oil pressure in the ratio, so the oil pressure, the temperature and the time are required to be adjusted, the oil pressure is gradually increased and is higher than the pressure of the traditional oil pressure floor, and the time is also properly prolonged, so the air bubble amount in the floor is controlled. Table 1 shows the pressure, time and temperature parameters of the conventional product and the product of the present application.
