Description

Technical Field

[0001] The utility model relates to the technical field of PVC coiled materials, in particular to a waterproof and wear-resistant PVC coiled material. Background Art

[0002] PVC coil, short for polyvinyl chloride coil, is a widely used polymer material. It's primarily made from PVC resin mixed with various additives like plasticizers, stabilizers, fillers, antioxidants, and UV absorbers. It's produced through a specific production process, such as calendaring. It contains fewer fillers and more plasticizers than PVC floor tiles. PVC is typically plasticized using a four-roller calender. After calendaring, the surface is smooth and flat, and after cooling, the edges are trimmed and coiled. Coil specifications vary by country. Soft PVC flooring is soft, elastic, and comfortable to the touch.

[0003] There is a waterproof and wear-resistant PVC coil with a Chinese patent announcement number of CN219486804U, which includes a coil body, wherein the outermost layer of the coil body is set as a wear-resistant layer, the inner layer of the wear-resistant layer is fixedly connected to an anti-corrosion layer, the inner layer of the anti-corrosion layer is fixedly connected to a waterproof layer, the inner layer of the waterproof layer is fixedly connected to a reinforcement layer, the inner layer of the reinforcement layer is fixedly connected to a PVC layer, the inner layer of the PVC layer is fixedly connected to an antibacterial layer, and the inner layer of the antibacterial layer is fixedly connected to an antioxidant layer. The present application provides a wear-resistant layer, an anti-corrosion layer and an antioxidant layer, wherein the wear-resistant layer is made of nano-aluminum oxide material, the anti-corrosion layer is made of epoxy resin material, and the surface of the antioxidant layer is coated with an antioxidant, thereby improving the wear resistance, anti-oxidation resistance and corrosion resistance of the coil, thereby improving the service life of the coil. However, this device still has some shortcomings.

[0004] This device adds multiple layers of functional materials, especially when using thicker or denser materials, which may reduce the air permeability of the entire roll, hinder the moisture exchange between the substrate and the outside world, and cause water vapor accumulation in the bottom layer or inside the structure, which may cause mildew or structural damage in the long term. In addition, there are no anti-slip grooves on the outer surface, which makes the roll have low anti-slip performance.

[0005] Therefore, we propose a waterproof and wear-resistant PVC membrane to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a waterproof and wear-resistant PVC coiled material to solve the problem that the existing device proposed in the above background technology adds multiple layers of functional materials, especially when thicker or denser materials are used, which may cause the air permeability of the entire coiled material to deteriorate, hindering the moisture exchange between the substrate and the outside world, resulting in water vapor accumulation in the bottom layer or inside the structure, which may cause mildew or structural damage in the long term, and the lack of anti-slip grooves on the outer surface makes the coiled material have low anti-slip performance.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a waterproof and wear-resistant PVC coil.

[0008] Preferably, a stabilizing layer is provided on one side of the waterproof layer, and a light stabilizer and a heat stabilizer are provided inside the stabilizing layer, and the stabilizing layer is evenly distributed.

[0009] By adopting the above technical solution and setting up light stabilizers and heat stabilizers, the waterproof layer can be protected from ultraviolet rays and high temperatures, thereby extending its service life.

[0010] Preferably, a flame retardant layer is provided on one side of the stabilizing layer, and the flame retardant layer is made of polyurethane and epoxy resin.

[0011] By adopting the above technical solution, the epoxy resin is located on the outer surface of the polyurethane, and the polyester amine molecules have the flame retardant principle, which can slow down the combustion speed. The epoxy resin layer generates a porous carbon foam layer when heated, which plays the role of oxygen isolation and flame retardancy, thereby improving the flame retardancy of the PVC coil.

[0012] Preferably, an environmentally friendly additive is provided on the outer surface of the flame retardant layer.

[0013] With the above technical solution, toxic gases will be generated by the coil body during use, which can easily affect the environment and human body. Therefore, setting environmentally friendly additives can effectively solve the harmful gases generated by the PVC coil during use.

[0014] Preferably, a wear-resistant layer is provided on one side of the environmentally friendly additive.

[0015] By adopting the above technical solution, the wear-resistant layer is made of silicone or silicon carbide and connected with the environmentally friendly additive by glue, so that the structure is made stronger and the loss of the environmentally friendly additive is prevented.

[0016] Preferably, an outer layer is provided on one side of the wear-resistant layer, and the outer layer is located at the outermost layer of the coil body. Anti-slip grooves are provided on the surface, and a plurality of anti-slip grooves are evenly distributed.

[0017] By adopting the above technical solution, the anti-skid property of the coil body is enhanced by providing anti-skid grooves on the surface of the outer layer and performing frosting treatment.

[0019] 1. The coil body, bottom layer, polyester fiber layer, glass fiber layer and waterproof layer are arranged symmetrically on both sides of the coil body. The double bottom layer provides a stable foundation for subsequent layers. The upper bottom layer is provided with a grid-like polyester fiber material, and the lower bottom layer is provided with a textured glass fiber material. This can enhance the strength and stability of the PVC coil structure. The waterproof layer is arranged on top of the polyester fiber layer and the glass fiber layer, and contains a polyurethane waterproofing agent inside, which makes the PVC coil have good waterproof properties.

[0020] 2. By setting up a stabilizing layer, a flame retardant layer, an environmentally friendly additive, a wear-resistant layer and an outer layer, the wear-resistant layer is made of silicone or silicon carbide and is arranged on the outer surface of the environmentally friendly additive, so that the PVC material has high wear resistance while protecting the environmentally friendly additive. The outermost layer of the PVC coil is provided with anti-slip grooves and is frosted, which enhances wear resistance while also increasing anti-slip properties. BRIEF DESCRIPTION OF THE DRAWINGS
