Description

Weight reduction structure of plastic plate

The technical field is as follows:

the utility model relates to a panel field specifically says a plastic panel subtract heavy structure.

Background art:

the plastic board generally selects stone powder with low price as a filling agent, the prepared board has higher density, the boards which are lighter are generally prepared by adopting foaming or hollow and wood powder adding modes, the boards can be used for paving the ground or paving the wall surface, and the boards all have the fatal defects that the balance performance is not good, the high-temperature deformation is easy, or the process is more complex and the cost is higher.

The utility model has the following contents:

the utility model aims to solve the technical problem that a structure that subtracts of plastic panel that the equilibrium is good, can effectively reduce weight is provided.

The technical solution of the utility model is that, a subtract heavy structure of plastic panel is provided, and it includes a plastic substrate at least, and plastic substrate top is equipped with pattern layer and transparent protective layer, and plastic substrate below is equipped with the slot concave to substrate surface, and the slot surface is equipped with the balancing layer.

Preferably, the balancing layer is melamine impregnated paper or a UV coating.

Preferably, the plastic substrate is made of plastic materials extruded by an extruder and pressed by two steel rollers.

Preferably, the transparent protective layer is formed with a texture.

Preferably, the grain corresponds to the pattern layer with a deviation of less than 2 mm.

Preferably, the thickness of the plastic substrate is 3.2-8mm, and the depth of the groove is 1-5 mm.

Preferably, the cross section of the groove is any geometric figure of square, arc and trapezoid.

Preferably, the plastic substrate is any one of PVC, PP, PET, PETG and POE.

Preferably, the transparent protective layer is formed by coating any one of UV, PUR and PVC resin and then curing.

Compared with the prior art after the scheme more than adopting, the utility model has the advantages of it is following: through set up the slot on the plastic substrate, though not reduce density, the panel weight of same size can alleviate a lot, especially thicker board, and the effect is more obvious, simultaneously, in order to solve and to set up the easy equilibrium problem that appears behind the hook groove, corresponds and has set up balanced layer.

Description of the drawings:

fig. 1 is a schematic structural diagram of an embodiment of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with respect to the following detailed description:

example 1

A weight-reducing structure of a plastic plate is shown in figure 1 and comprises a plastic substrate 1, a pattern layer 2 and a transparent protective layer 3 are sequentially arranged above the plastic substrate 1, a groove 14 which is concave to the surface of the substrate is arranged below the plastic substrate 1, and a balance layer 5 is arranged on the surface of the groove 14. Wherein the plastic base material is any one of PVC, PP, PET, PETG and POE; the transparent protective layer can be formed by coating and curing UV, PUR, PVC and other resins; the balancing layer is made of a material with high hardness, such as a film with low oil content or without oil content, and the thickness of the balancing layer is changed to balance the board.

The method for manufacturing the weight-reducing structure of the plastic plate comprises the following steps of extruding a plastic material through an extruder, and pressing the extruded plastic material through two steel rollers to obtain the weight-reducing structure of the plastic plate, wherein the steel roller in contact with the surface is provided with concave-convex grains or plain grains, the steel roller in contact with the bottom surface is provided with a groove, as a preferred mode, a balance layer is laid on the bottom surface of the plastic plate before the groove is pressed through a rubber roller, the balance layer is distributed on the bottom surface of the plastic plate including the groove after the groove is pressed, a pattern layer covers the upper surface of the plastic plate before the grains are pressed through the rubber roller, and a transparent protective layer covers the pattern layer through the rubber roller, and the grains are formed on the transparent protective layer after the pressing. And the grains correspond to the pattern layer, and the deviation is less than 2 mm. In addition, the groove, the pattern layer and the protective layer can be formed at one time without using any adhesive. In the prior art, part of the light wall boards are also provided with grooves, and the grooves are used for increasing the contact area of glue during bonding. The production process is limited by the process, the substrate with the groove can not be formed at one time, the substrate with the groove can be produced firstly, and the pattern layer and the transparent layer are attached by glue after the substrate is cooled.

Or the embossing plate, the transparent protective layer, the pattern layer, the plastic substrate, the balance layer and the groove plate are sequentially laid on a flat iron disc and are conveyed into a press through a conveyor belt, and the groove weight reducing structure is directly manufactured through high temperature and high pressure, wherein the cross section of the groove weight reducing structure is any geometric figure of a square shape, an arc shape and a trapezoid shape.

The plastic board can be used for floors or wallboards. Considering that the traditional wallboard groove is obtained by adjusting an extrusion ground, the groove can be flattened due to pressure during lamination, so that the groove cannot be laminated on line, a base material with the groove is firstly prepared, a surface skin is laminated on the base material by glue after cooling, and the surface skin needs to be subjected to prefabricated embossing. This application is through creative improvement for the laminating epidermis is directly extruded to the wallboard, presses the decorative pattern on, when laminating the epidermis, presses the slot with the shading compression roller and goes, and according to the in-service use condition, does the injecing to the size of slot, and plastic substrate thickness is 3.2-8mm, and the slot degree of depth is 1-5mm, avoids too dark slot to influence surface effect.

By arranging the grooves on the plastic base material, although the density is not reduced, the weight of the board with the same size can be reduced, and especially the effect is more obvious when the board is thicker.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All utilize the utility model discloses equivalent structure or equivalent flow transform that the specification was done all are included within the patent protection scope of the utility model.
