Description

Anti-deformation plastic splicing board

This creation is related to splicing panels used to splice together to form a floor or wall panel, especially a plastic splicing panel that prevents deformation.

Existing plastic floor or wall panels are usually composed of multiple plastic splicing panels. This type of plastic splicing panels are usually formed by co-extrusion so that they have a hard inner layer and a soft non-slip surface. The structure can refer to Taiwan's new M572393 patent. The problem is that the plastic splicing board, such as the plastic splicing board used for splicing to form an outdoor floor, is prone to thermal deformation after being heated for a long time, which makes the flat plastic splicing board as shown in Figure 5(a) deform into an inverted Arc, as shown in Figure 5(b). The deformed plastic splicing board will not only push the adjacent plastic splicing board, destroy the surface flatness of the entire floor, but also cause poor drainage and cause water accumulation problems.

Therefore, how to solve the problem that the existing co-extruded plastic splicing panels are easily deformed by heat is an urgent task.

This creation provides a plastic splicing board with anti-deformation, which includes a hard plastic core board and a soft skin layer formed on the surface of the hard plastic core board. The hard plastic core board contains a thermal deformation-resistant modifier and is compatible with the soft The cortex is co-extruded and formed together. The opposite sides of the plastic splicing board respectively form a first splicing portion and a second splicing portion, and the first splicing portion and the second splicing portion are used for splicing another plastic splicing board. The two opposite sides of the plastic splicing board are curved to form an arc, the highest point of the arc is located at a center point between the two sides, and the height H of the highest point of the arc is the two 0.5 to 1.5% of the width W between the sides, preferably 1%.

In an embodiment, the first splicing part and the second splicing part of the present invention are each a tongue and groove. In another embodiment, the first splicing part of the invention is a tenon and the second splicing part of the invention is a tenon.

In one embodiment, the above-mentioned soft skin layer of the present invention covers the entire surface of the hard plastic core board, and the hard plastic core board and the soft skin layer are bent together to form the above-mentioned arc.

Compared with the prior art, the plastic splicing board of the present invention has the above-mentioned specific arc structure and contains an anti-heat deformation agent, so it is not easy to be deformed by heat, and can solve the problem that the conventional plastic splicing board is easily deformed by heat.

Figure 1 shows a preferred embodiment of the plastic splicing board 1 of the present invention, which has a left side 11 and a right side 12 opposite to each other, and a front side 13 and a rear side 14 opposite to each other. Both sides (for example, the left side 11 and the right side 12) respectively form a first splicing portion 111 and a second splicing portion 121. The first splicing portion 111 and the second splicing portion 121 are used for splicing another plastic splicing board 1, In order to form a floor or siding. In this embodiment, the first splicing portion 111 is a tongue and groove extending along the longitudinal direction of the plastic splicing board 1, and the second splicing portion 121 is also the same.

In this embodiment, the plastic splicing board 1 includes a hard plastic core board 101 and a soft skin layer 102 formed on part or all of the hard plastic core board 101, and the two are preferably extruded in a co-extrusion method. . Among them, the rigid plastic core board 101 has a strong structure and pressure resistance, and it can be made of foamed or non-foamed plastic materials such as polyethylene, polyvinyl chloride, and polystyrene. In order to prevent thermal deformation, a thermal deformation-resistant modifier can be added to the material forming the rigid plastic core board 101. As for the soft skin 2, it has both elasticity, anti-slip and abrasion resistance, and can be made of elastic materials such as natural rubber, Thermoplastic Urethane (TPU) or Thermoplastic Rubber (TPR) , But not limited to this. In addition, the hard plastic core board 101 can be solid or partially hollow. In this embodiment, the plastic core board 1 is partially hollow, and has a plurality of holes 10 extending from the front side 13 to the rear side 14. , And each channel 10 is parallel to the tongue and groove.

As shown in Figure 2, the opposite sides of the plastic splicing board 1 (left side 11 and right side 12) are all curved to form an arc, and the highest point of the arc is between the left side 11 and the right side 12 The height H of the highest point of the arc is about 0.5 to 1.5%, preferably 1%, of the width W between the left side 11 and the right side 12 of the plastic splicing board 1. For example, if W=140mm, then H=1.4mm. In this way, the plastic splicing board 1 will have good thermal deformation resistance, which can reduce the use amount of the thermal deformation-resistant modifier of the rigid plastic core board 101.

Figures 3 and 4 show another plastic splicing plate 1a, which is roughly the same as the plastic splicing plate 1, except that its second splicing portion 121a is a convex extending along the length of the plastic splicing plate 1. The tenon can be inserted into the above-mentioned groove.

Because the plastic splicing board 1 of this invention has the above-mentioned specific arc structure and contains heat-resistant deformation agent, it is not easy to be deformed by heat. It is quite suitable for assembling outdoor floors or wall panels. problem. In addition, the above-mentioned specific arc-shaped structure of the plastic splicing board 1 of the present invention can make its surface present an arc-shaped drainage surface gradually lowering to the left and right sides, which not only has no water accumulation problem, but also helps drainage.
