Description

Technical Field

[0001] The utility model relates to the technical field of flooring, in particular to a stone plastic floor. Background Art

[0002] Stone plastic floor, also known as "PVC sheet" floor, is a new type of floor decoration material. Stone plastic floor is widely used in the construction industry due to its excellent performance. Its flame retardant performance reaches B1 level, it is not afraid of water or moisture, and can be installed in bathrooms and toilets. The surface of traditional stone plastic floor is a wear-resistant layer of PVC material, which can be easily scratched by heavy objects and sharp objects. Its service life in public places is often no more than two years; while the surface of ordinary laminate floor is hot-pressed cured melamine formaldehyde resin, which has high strength and scratch resistance, but because the base material contains wood fiber, it is not resistant to blisters and is prone to bulging after being damp, so it is not suitable for use in humid environments.

[0003] The impregnated paper on the surface of the existing laminate flooring is combined with the substrate by hot pressing. Since the SPC flooring contains PVC components, it cannot withstand the temperature and pressure of hot pressing of the laminate flooring and will soften and deform during hot pressing. Therefore, the impregnated paper cannot be directly combined with the SPC flooring.

[0004] With the extensive use of stone plastic floor, people have higher and higher quality requirements for stone plastic floor. In view of this, there is an urgent need for a stone plastic floor to at least solve the above-mentioned disadvantages. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model aims to provide a stone plastic floor to improve the scratch resistance of the existing products.

[0006] In order to solve the above technical problems, the utility model provides a stone plastic floor, including a stone plastic floor substrate, a reactive polyurethane hot melt adhesive bonded to the upper surface of the stone plastic floor substrate, a fireproof kraft paper bonded to the upper surface of the reactive polyurethane hot melt adhesive, and an impregnated paper pressed on the upper surface of the fireproof kraft paper.

[0007] In one embodiment, the thickness of the fireproof kraft paper of the stone plastic floor provided by the utility model is 0.4-0.6 mm.

[0008] In one embodiment, the thickness of the stone plastic floor substrate of the stone plastic floor provided by the utility model is 5 to 8 mm.

[0009] In the absence of conflict, the technical solutions of the aforementioned embodiments may be implemented individually or in combination.

[0010] The beneficial effects of the stone plastic floor provided by the embodiment of the present application are:

[0011] The stone plastic floor can withstand high temperatures of 100°C and will not debond at 100°C, meeting the use requirements in floor heating environments. The wear resistance can be adjusted according to customer needs, with a maximum wear resistance of 12,000 revolutions and a scratch resistance of level 5, making it suitable for bathrooms, toilets, and public places. Compared with other stone plastic floors on the market, the stone plastic floor provided by the utility model has excellent scratch resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the present application. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation on the present invention. In the accompanying drawings:

[0013] Figure 1 It is a structural schematic diagram of the stone plastic floor of the embodiment. DETAILED DESCRIPTION

[0014] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0015] See also Figure 1 In this embodiment, the stone plastic floor includes a stone plastic floor substrate 1, a reactive polyurethane hot melt adhesive 2 bonded to the upper surface of the stone plastic floor substrate 1, a fireproof kraft paper 3 bonded to the upper surface of the reactive polyurethane hot melt adhesive 2, and an impregnated paper 4 pressed on the upper surface of the fireproof kraft paper 3.

[0016] In this embodiment, the thickness of the fireproof kraft paper 3 of the SPC floor is 0.4-0.6 mm.

[0017] In this embodiment, the thickness of the SPC floor substrate 1 of the SPC floor is 5-8 mm.

[0018] In this embodiment, the stone plastic floor is obtained by the following method:

[0019] In this embodiment, the impregnated paper 4 is made by spraying aluminum oxide wear-resistant powder on the base paper with printed patterns, then coating the base paper with impregnating resin glue, and then drying and curing. The preparation process of the impregnated paper 4 is the same as the preparation process of the impregnated paper used in the existing laminate flooring, and the utility model does not make any improvement thereto. The corresponding impregnated paper products can also be purchased on the market.

[0020] In this embodiment, the fireproof kraft paper is made of kraft paper, phenolic resin glue or urea-formaldehyde resin glue after dipping, composite hot pressing, and the corresponding fireproof kraft paper can be purchased on the market. The preparation process of the fireproof kraft paper is not improved in the present utility model. The function of the fireproof kraft paper 3 is to provide a stable support surface for the impregnated paper above so that it can be pasted on the stone plastic floor substrate 1.

[0021] During production, a hot press is first used to press the impregnated paper 4 onto the fireproof kraft paper 3 to obtain a composite body, ensuring that the two are tightly combined without bubbles or dislocation. A reactive polyurethane hot melt adhesive (purchased from Changzhou Lanshuo brand) is evenly applied to the stone plastic floor substrate 1. Then the pressed composite body is pasted on the stone plastic floor substrate 1, and after flattening, cooling and other treatments, the stone plastic floor is obtained. The above process is also a conventional process mastered by those skilled in the art, and the utility model does not make any improvements thereto.

[0022] Based on this, the stone plastic floor provided by this embodiment can withstand a high temperature of 100 degrees without debonding, meeting the use requirements in a floor heating environment. The wear resistance can be adjusted according to customer needs, with a maximum wear resistance of 12,000 revolutions, and a scratch resistance of level 5, and can be used in bathrooms, toilets, and public places. Compared with other stone plastic floors on the existing market, the stone plastic floor provided by the utility model has excellent scratch resistance, and because the surface layer is impregnated paper 4, it has wood grain or other patterns, making it more beautiful and high-end.

[0023] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
