Description

PVC floor with anti-slip performance and preparation method thereof Technical Field

[0001] The invention belongs to the technical field of floor preparation, and relates to a PVC floor with anti-slip performance and a preparation method thereof. Background Art

[0002] At present, indoor floors mainly include wooden floors, ceramic floors and plastic floors. Wooden floors give people a feeling of returning to nature, but they are expensive and require special wood species and high-quality wood. Not only are they extremely resource-constrained, but they are also not flame retardant or fireproof. Ceramic floors have problems such as brittleness, high specific gravity, and discomfort underfoot, and ceramic floors generally have poor anti-slip performance. Plastic floors are easy to process, low in cost, and light in weight, but their mechanical strength is inferior to that of ceramics, and their anti-slip performance needs to be further improved.

[0003] PVC flooring is primarily made from PVC, with the addition of appropriate additives and stabilizers. It is non-toxic, odorless, moisture-proof, and heat-resistant. It is also lightweight and easy to transport and install. PVC is also fire-resistant, preventing combustion and preventing the spread of fire, demonstrating excellent flame retardancy. However, PVC itself has a low density and mechanical strength, making it prone to deformation over time. This can lead to slippage and shortens its lifespan. Furthermore, the anti-slip properties of the PVC surface need further improvement. Summary of the Invention

[0004] The present invention aims to provide a PVC floor with anti-slip properties and a preparation method thereof, belonging to the technical field of floor preparation. The present invention comprises the following steps: mixing polyvinyl chloride resin powder, a stabilizer, a plasticizer, and sodium bicarbonate, followed by a first kneading to obtain a pre-foamed polyvinyl chloride material, which is then immersed in a calcium chloride solution, taken out and dried, and then subjected to a second kneading, followed by calendering, cooling and cutting to obtain a polyvinyl chloride foam layer; mixing polyvinyl chloride resin powder, an aminosilane coupling agent, zeolite, activated carbon, silica aerogel microspheres, glass fiber, a stabilizer, a plasticizer, and a flame retardant, followed by mixing, kneading, calendering, cooling and cutting to obtain a polyvinyl chloride anti-slip layer; and stacking the polyvinyl chloride anti-slip layer on top of the polyvinyl chloride foam layer and performing hot pressing to obtain a PVC floor with anti-slip properties. During use, the lower side of the polyvinyl chloride foam layer is sprayed with aluminum sol and silica sol and then bonded to a cement floor. The invention discloses a method for preparing a polyvinyl chloride foam layer. The method comprises the following steps: firstly, in the first mixing, sodium bicarbonate decomposes to generate sodium carbonate, and simultaneously generates pores to form a foam structure. The method is then soaked in a calcium chloride solution. The foam structure promotes the soaking efficiency of the calcium chloride solution. After soaking, the sodium carbonate and the calcium chloride generate calcium carbonate. The porous structure after foaming promotes the interaction between the floor and the cement ground, thereby improving the adhesion. At the same time, the calcium carbonate can be used as a filler to enhance the strength of the polyvinyl chloride foam layer. Zeolite, activated carbon and silica aerogel microspheres, which are adsorbent materials with different pore sizes, are added to the polyvinyl chloride anti-skid layer to synergistically enhance the surface anti-skid performance of the floor. The aminosilane coupling agent utilizes the interaction between the positive charge of the amino group and the negative charge on the surface of the polyvinyl chloride to further promote the uniform dispersion of the inorganic adsorbent in the polyvinyl chloride and the adhesion to the surface of the polyvinyl chloride anti-skid layer. During use, aluminum sol and silica sol are sprayed under the polyvinyl chloride foam layer, and the two sols synergistically improve the adhesion of the floor on the cement ground.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A method for preparing a PVC floor with anti-slip performance, the method comprising the following steps:

[0007] (1) preparing a polyvinyl chloride foam layer;

[0008] (2) Preparation of polyvinyl chloride anti-slip layer;

[0009] (3) The polyvinyl chloride anti-slip layer is stacked on the polyvinyl chloride foam layer and hot-pressed to obtain a PVC floor with anti-slip properties.

[0010] As a preferred technical solution of the present invention, the method for preparing the polyvinyl chloride foam layer in step (1) comprises the following steps:

[0011] S1 70-90 parts by weight of polyvinyl chloride resin powder, 1-5 parts by weight of sodium bicarbonate, 0.8-2 parts by weight of a stabilizer, 10-15 parts by weight of a plasticizer, 0.5-1.5 parts by weight of a flame retardant are mixed and stirred for the first time to obtain a pre-foamed polyvinyl chloride material;

[0012] S2. Soak the pre-foamed polyvinyl chloride material in a calcium chloride aqueous solution, take it out and dry it, perform a second mixing, and then calender, cool, and cut it to obtain a polyvinyl chloride foam layer.

[0013] As a preferred technical solution of the present invention, the time for the first mixing in S1 is 8-12 minutes, and the temperature for the first mixing is 130-140°C.

[0014] As a preferred technical solution of the present invention, the mass concentration of the calcium chloride aqueous solution in S2 is 35-55%, the soaking means just immersing the pre-foamed polyvinyl chloride material, the soaking time is 2-3h, the temperature of the second mixing is 140-150°C, and the time of the second mixing is 10-15min.

[0015] As a preferred technical solution of the present invention, the method for preparing the polyvinyl chloride anti-slip layer in step (2) comprises the following steps:

[0016] 70-90 parts by weight of polyvinyl chloride resin powder, 1-3 parts by weight of aminosilane coupling agent, 8-12 parts by weight of zeolite, 6-9 parts by weight of activated carbon, 7-9 parts by weight of glass fiber, 0.5-1.2 parts by weight of stabilizer, 8-13 parts by weight of plasticizer and 1-2 parts by weight of flame retardant are stirred and mixed, then kneaded, calendered, cooled and cut to obtain a polyvinyl chloride anti-slip layer.

[0017] As a preferred technical solution of the present invention, the temperature of the hot pressing in step (3) is 140-150°C, the time of the hot pressing is 30-40 minutes, and the pressure of the hot pressing is 16-20 MPa.

[0018] The PVC floor with anti-slip performance prepared by the above preparation method.

[0019] As a preferred technical solution of the present invention, the thickness of the polyvinyl chloride foam layer is 12-20 mm, and the thickness of the polyvinyl chloride anti-slip layer is 2-4 mm.

[0020] The above-mentioned method for using the PVC floor includes the following steps: cleaning the cement floor to remove debris and dust, spraying silica sol and aluminum sol on the bottom of the polyvinyl chloride foam layer of the PVC floor in sequence, and then attaching the bottom of the sprayed polyvinyl chloride foam layer to the cleaned cement floor.

[0021] Furthermore, the silicon content in the silica sol is 10-15wt%, the aluminum content in the alumina sol is 8-12wt%, and the spraying amount of the silica sol is 12-18g / m 2 The spraying amount of the aluminum sol is 18-25g / m 2 .

[0022] Beneficial effects of the present invention:

[0023] (1) In the process of preparing the polyvinyl chloride foam layer, if the foaming agent sodium bicarbonate and the reinforcing filler are directly added to the polyvinyl chloride resin powder for mixing, the dispersion between the large amount of calcium carbonate filler and the polyvinyl chloride is poor, which ultimately leads to the mechanical strength of the polyvinyl chloride foam layer not being guaranteed; in the process of preparing the polyvinyl chloride foam layer of the present invention, sodium bicarbonate decomposes to produce sodium carbonate during the first mixing, and at the same time produces pores to form a foaming structure, which is then soaked in a calcium chloride solution. The foaming structure promotes the soaking efficiency of the calcium chloride solution. After soaking, sodium carbonate and calcium chloride generate calcium carbonate, and the calcium carbonate is evenly attached to the porous structure. Calcium carbonate as a filler can effectively enhance the strength of the polyvinyl chloride foam layer. After foaming, the porous structure promotes the interaction between the floor and the cement floor, thereby improving the adhesion;

[0024] (2) Adding adsorbent materials of different pore sizes, such as zeolite and activated carbon, to the polyvinyl chloride anti-slip layer can synergistically enhance the anti-slip properties of the floor surface. The aminosilane coupling agent utilizes the interaction between the positive charge of the amino group and the negative charge on the surface of the polyvinyl chloride to further promote the uniform dispersion of the inorganic adsorbent in the polyvinyl chloride and the adhesion to the surface of the polyvinyl chloride anti-slip layer.

[0025] (3) During use, aluminum sol and silica sol are sprayed under the polyvinyl chloride foam layer. Combined with the porous structure of the polyvinyl chloride foam layer, the two work together to improve the adhesion of the floor to the cement floor. Implementation Method
