Abstract

The utility model provides a plastic floor tile, which comprises a substrate layer, a transparent PVC surface layer adhibited on the upper surface of the substrate layer and a balancing bottom layer adhibited on the lower surface of the substrate layer; wherein, the inner surface of the transparent PVC surface layer is provided with a floral pattern; and the substrate layer is made of stone-plastic floor tile mixture. The stone-plastic floor tile mixture is the mixture of PVC and calcium carbonate powder. Meanwhile, since the swell factor of the calcium carbonate powder material is small and temperature affection on the calcium carbonate powder material is low, the dimension change of the substrate made of the stone-plastic floor tile mixture, which is caused by thermal expansion and cold contraction, is little, as a result, in the process of use, the distance between the adjacent plastic floor tiles cannot be too large, i.e., the dimension change rate is low, and stability is good. Moreover, the balancing bottom layer adhibited on the lower surface of the substrate layer not only can protect the substrate layer but also can prolong the whole service life of the plastic floor tile.

Description

Plastic floor tile

Technical field

The utility model relates to a kind of plastic floor tile.

Background technology

The plastic floor tile light weight is inexpensive, and pattern, color change are various, and construction easily, so liked by the customer.As shown in Figure 1, the patent No. is that the utility model patent of ZL00245538.2 discloses a kind of plastic floor tile structure, comprise PVC substrate layer 11 and press the PVC transparent surface layer 13 that adheres to substrate layer 11 upper surfaces, the inner face elder generation printing pattern 131 of PVC transparent surface layer 13, republish white layer 2, and mat white layer 2 is pressed the bonding integrator with PVC transparent surface layer 13 and substrate layer 11.In this patent, owing to omitted traditional white cortex, but directly print white layer 2 at the inner face of PVC transparent surface layer 13, reduced cost; Simultaneously, solved between each layer of plastic floor tile of traditional structure problem in conjunction with difficulty.But it still has following defective: at first, because substrate layer 11 uses the PVC material fully, its price comparison height causes the plastic floor tile cost still than higher; Secondly, because the coefficient of expansion of PVC material is bigger, to the variations in temperature sensitivity, so in use, Chang Yin expands with heat and contract with cold and causes the distance between the adjacent plastic floor tile to change significantly, drum takes place when temperature is high to be stuck up, when temperature is low between the adjacent plastic floor tile distance too big, so the poor stability of this plastic floor tile.

In view of the defective that above-mentioned prior art exists, the design people proposes a kind of plastic floor tile, can avoid defectives such as cost height, poor stability, makes it have more practicality.

Summary of the invention

The purpose of this utility model is to provide that a kind of cost is low, the plastic floor tile of good stability.

For achieving the above object, embodiment of the present utility model provides a kind of plastic floor tile, comprise substrate layer and the PVC transparent surface layer that is fitted in above the substrate layer, wherein the inner face of PVC transparent surface layer is provided with floral designs and white layer, it also comprises the balancing layer that is fitted in below the substrate layer, and wherein said substrate layer is moulded the floor tile mixture by stone and made.

Described balancing layer is made by high density PVC material.

The thickness of described balancing layer is the 1/30-1/10 of described substrate layer thickness.

Described PVC transparent surface layer, substrate layer and balancing layer calendering are combined into one.

As shown from the above technical solution, the advantage and the good effect of the plastic floor tile of embodiment of the present utility model are: in the utility model, because substrate layer is moulded the floor tile mixture by stone and made, stone is moulded the mixture that the floor tile mixture is PVC and Paris white.Because the price of Paris white is lower than PVC, be beneficial to the manufacturing cost that reduces whole plastic floor tile as base material so use this stone to mould the floor tile mixture.Simultaneously, because the expansion system number of Paris white material is little, temperature influence is little, so it is smaller to mould the change in size that base material that the floor tile mixture makes produces because of expanding with heat and contract with cold by stone, so in use, be not prone to the excessive problem of distance between the adjacent plastic floor tile, promptly size changing rate is low, good stability.In addition, be fitted with balancing layer below substrate layer, it has not only protected substrate layer, simultaneously can the balance sheet ply stress, and make floor tile not be prone to drum and stick up, prolong the whole service life of plastic floor tile.

With reference to the accompanying drawing description of a preferred embodiment, above-mentioned and other purpose of the present utility model, feature and advantage will be more obvious by following.

The specific embodiment

To describe specific embodiment of the utility model in detail below.Should be noted that the embodiments described herein only is used to illustrate, be not limited to the utility model.

As shown in Figure 2, plastic floor tile of the present utility model comprises substrate layer 11, calendering PVC transparent surface layer 13 and the balancing layer 3 of calendering below substrate layer 11 on substrate layer 11.Wherein, republish white layer 2 or other chromatographs at the inner face elder generation printing pattern pattern of PVC transparent surface layer 13.Substrate layer 11 is made by 10% PVC and 90% Paris white.The PVC of substrate layer 11 and the ratio of Paris white can also be PVC 80%, Paris white 20%; PVC 20%, Paris white 80%; PVC 60%, Paris white 40%; PVC 40%, Paris white 60%; In fact,, improve stability, adopt 10% PVC and 90% Paris white making substrate layer 11 usually for reducing cost.This is that to mould the floor tile mixture be known in the plastic floor tile field for stone that raw material is made by PVC and Paris white.Because the cost of Paris white is lower, be beneficial to the manufacturing cost that reduces whole plastic floor tile as base material so use this stone to mould the floor tile mixture.Simultaneously, because the expansion system number of Paris white material is little, so, even variations in temperature is bigger, it is smaller to mould the change in size that base material that the floor tile mixture makes produces because of expanding with heat and contract with cold by stone, so in use, is not prone to the excessive problem of distance between the adjacent plastic floor tile.Balancing layer 3 is made by high density PVC material.The thickness of balancing layer 3 is 1/20 of substrate layer 11 thickness, is mainly used in protection substrate layer 11.The thickness of balancing layer 3 can also be 1/10,1/15,1/25,1/30 etc. of substrate layer 11 thickness.

In the utility model, use calendering technology to produce plastic floor tile, thickness is even, the productivity ratio height, and each interlayer adhesive strength is stronger, and reduced the product fraction defective.

Though described the utility model with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.The spirit or the essence that do not break away from utility model because the utility model can specifically be implemented in a variety of forms, so be to be understood that, the foregoing description is not limited to any aforesaid details, and should be in the spirit and scope that claim limited of enclosing explain widely, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
