Description

Technical Field

[0001] The utility model belongs to the technical field of home decoration materials, relates to floors, and in particular to an anti-skid and shock-absorbing reinforced floor for floor heating. Background Art

[0002] Laminate flooring, scientifically known as impregnated paper laminate flooring, consists of a wear-resistant layer, a decorative layer, a high-density base layer, and a balancing layer. It is popular among consumers for its wear-resistant and impact-resistant surface, easy maintenance, rich texture, and high cost-effectiveness.

[0003] my country's demographic development has entered a new normal, with an aging population becoming increasingly severe. Influenced by traditional values ​​and economic conditions, 90% of my country's elderly choose to live at home. This has led to new demands for the functionality of home furnishings designed to provide greater care and protection for the elderly. Existing flooring materials, such as tile flooring, are relatively hard. In daily life, surface friction decreases when the floor comes into contact with water, making it very easy to slip. Furthermore, their impact absorption is poor, resulting in limited shock absorption and often causing serious injuries. As living standards improve, more and more families are opting for underfloor heating. Wood is a naturally porous material with poor thermal conductivity, slow heating, and low heat transfer efficiency. Under underfloor heating conditions, changes in moisture content can lead to cracking or deformation, compromising the use of wooden flooring. Summary of the Invention

[0004] In view of the deficiencies in the above-mentioned prior art, the present invention provides a non-slip and shock-absorbing laminate flooring that can be used under floor heating conditions to solve the problems raised in the above-mentioned background technology.

[0005] The utility model adopts the following technical solutions:

[0006] A non-slip and shock-absorbing laminate floor for floor heating, comprising, from top to bottom, a decorative layer, a special substrate layer for floor heating, a balancing layer, and a shock-absorbing layer. The special substrate layer for floor heating is a sandwich structure, comprising a first geothermal substrate layer, a moisture-proof fiberboard, and a second geothermal substrate layer. The first geothermal substrate layer and the second geothermal substrate layer have the same thickness, 1 to 3 mm, preferably 2 mm, and are high-density, low-swelling moisture-proof fiberboard; the moisture-proof fiberboard has a thickness of 2 to 6 mm, preferably 4 mm, and is a carbon crystal board or a bamboo charcoal pure formaldehyde board; the shock-absorbing layer is a polypropylene foam EPP layer with a density of 25 to 35 kg / m 3 , thickness 3 to 4 mm.

[0007] In a preferred disclosed example of the present invention, the decorative layer is a melamine facing paper with liquid aluminum oxide sprayed on the surface, with a thickness of 0.1 to 0.2 mm. The surface pattern of the facing paper can imitate natural wood grain, stone grain and other patterns.

[0008] In the preferred disclosed embodiment of the present utility model, the high-density, low-swelling, moisture-proof fiberboard has a density of 1000-1200 kg / m 3 , water absorption expansion rate ≤5%.

[0009] In a preferred disclosed example of the present invention, the carbon crystal board is composed of a composite of wood fiber, graphite powder and inorganic minerals, wherein the graphite powder is flaky, 300-400 mesh, and commercially available; the bamboo charcoal pure formaldehyde board is selected from Daya Artificial Board Group Co., Ltd.

[0010] In a preferred disclosed example of the present invention, the balancing layer is balancing paper with a thickness of 0.1 to 0.2 mm, which plays the role of moisture-proofing and balancing the tension of the board.

[0011] In a preferred embodiment of the present invention, the polypropylene foam EPP layer is provided with circular holes with a diameter of 4 to 6 mm, preferably 5 mm, at intervals of 20 to 40 cm, preferably 30 mm, in both the length and width directions. The thickness of the circular holes matches the thickness of the shock-absorbing layer. The polypropylene foam EPP material has excellent impact absorption, shock absorption and cushioning effects, and good temperature and weather resistance, making it suitable for use with floor heating.

[0012] In a preferred disclosed embodiment of the present invention, a tongue and groove are respectively provided on the long side and the short side of the floor, which are connected by a lock.

[0013] The surface of the laminate floor disclosed by the utility model has concave and convex textures such as hemp surface and relief. The texture is molded by a steel template when pressed, and the surface has an anti-slip function. During the processing of the floor, the lock is sealed with a mortise and tenon around the periphery, and a liquid nano-silica waterproof edge sealing agent is used to spray the exposed areas around the base material of the mortise and tenon and the chamfered inclined surfaces of the floor.

[0014] Beneficial effects

[0015] The anti-skid and shock-absorbing laminate flooring for floor heating disclosed in the present invention has a surface with concave and convex textures such as hemp surface and relief, and a sliding friction coefficient of 0.4 to 0.6. The floor can play an anti-skid role for the elderly in their daily life at home; the floor base material adopts a sandwich structure, with a symmetrical combination of upper, middle and lower layers. The upper and lower layers are high-density moisture-proof fiberboard, which has good waterproof and moisture-proof properties. After long-term use under floor heating, the floor will not deform or crack, and its dimensional stability is improved. At the same time, graphite powder is added to the middle layer. Graphite is a good thermal and electrical conductive material. It is evenly mixed with wood fiber and fills the gaps between wood fibers to form a continuous and stable heat conduction channel. The thermal conductivity of the floor under floor heating conditions is 15 to 18°C / h, while the thermal conductivity of ordinary laminate flooring is about 10°C / h, which effectively increases the heating rate and reduces heat loss; the back of the floor is made of shock-absorbing material EPP, which is an environmentally friendly material formed by CO2 inflation foaming. It has excellent impact shock absorption, heat resistance, moisture resistance, tear resistance and other properties. The impact absorption rate of ordinary laminate flooring, ceramic tiles and other flooring materials is below 20%, and the impact absorption rate is above 45%. The impact absorption performance is improved, and the shock absorption and cushioning effect is obvious, which reduces the damage caused by falls to the elderly; the shock-absorbing pad is equipped with continuous circular holes, and heat can be transferred to the floor through the hole cavity, thereby improving the thermal conductivity efficiency of the floor.
