Description

Technical Field

[0001] This utility model relates to the technical field of handle protection equipment, specifically to a PVC handle cover with good reflective effect and durability. Background Technology

[0002] In people's daily production, life, and work, some commonly used tools or workpieces are not easily spotted at night, and if left at the work site, they may even pose safety hazards. Reflective materials such as reflective film and reflective cloth are widely used in various road traffic safety facilities with relatively regular shapes or flat surfaces, such as traffic signs and markings, raised pavement markers, outline markings, traffic cones, crash barriers, and warning clothing. However, when reflective film is pasted onto objects with complex shapes and small volumes, it is easily torn under external force, and peeling can easily occur between the layers bonded by adhesive. In addition, the adhesive backing of the reflective film is prone to falling off and wear, all of which significantly affect the service life and reflective effect of the reflective film. PVC, as a general-purpose plastic, has excellent processing performance, mechanical properties, and wear resistance. After adding plasticizers, it can be made into flexible PVC. In addition, the use of transparent stabilizers in PVC formulations can give flexible PVC excellent transparency. Therefore, this utility model proposes a PVC handle cover with good reflective effect and durability to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a PVC handle cover with good reflective effect and durability. By thermoforming the base material layer onto the outer surface of the handle tool and thermoforming the outer surface of the reflective layer with a transparent layer, the handle cover has a durable reflective effect. At the same time, the transparent layer protects the reflective layer, significantly improving the wear resistance and dirt resistance of the handle cover, and making it more durable. Compared with the smooth outer surface of the handle tool, the reflective layer is more firmly and durablely covered on the outer surface of the base material layer, and the transparent layer shields the reflective layer, effectively preventing the reflective layer from peeling off.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a PVC handle cover with good reflective effect and durability, including a tool handle, and a substrate layer that is thermoformed and fixed to the outer side of the tool handle. The outer side of the substrate layer is covered with a reflective layer, and the outer side of the reflective layer is thermoformed and fixed with a transparent layer.

[0005] This utility model discloses a PVC handle cover with good reflective effect and durability. By thermoforming a base material layer to cover the outer surface of the handle tool, and thermoforming a transparent layer to cover and fix the outer surface of the reflective layer, the handle cover has a durable reflective effect. At the same time, the transparent layer protects the reflective layer, which significantly improves the wear resistance and dirt resistance of the handle cover and makes it more durable. Compared with the smooth outer surface of the handle tool, the reflective layer is firmly covered and its durability is significantly improved on the outer surface of the base material layer. In addition, the transparent layer shields the reflective layer and effectively prevents the reflective layer from peeling off.

[0006] The preferred technical solution is that the substrate layer is made of polyvinyl chloride paste and fixed to the outer surface of the tool handle by dip-coating thermoforming. Polyvinyl chloride paste is economical, and the dip-coating thermoforming process can be used to process the substrate layer on handles of any shape and size, ensuring the smooth preparation and implementation of the handle cover of this utility model.

[0007] A further preferred technical solution is that the polyvinyl chloride paste is a colored polyvinyl chloride paste. The substrate layer can be made in any color, while the reflective layer can be made into an intermittently distributed strip or ring structure to meet the diverse color requirements of the handle sheath.

[0008] Another preferred technical solution is that the reflective layer is a reflective film adhesively fixed to the outer side of the substrate layer, or the reflective layer is formed by curing reflective paint applied to the outer side of the substrate layer. The reflective layer can be a commercially available reflective film with adhesive backing, or it can be formed by curing reflective paint. That is, the method of covering the outer side of the substrate layer with the reflective layer can be flexibly selected according to actual needs.

[0009] A further preferred technical solution is that the retroreflection coefficient of the reflective layer is ≥500cd•lx. ⁻¹ •m ⁻² This ensures that the handle cover of this utility model has good overall reflective properties.

[0010] Another preferred technical solution is that the transparent layer is formed by coating and fixing a transparent polyvinyl chloride paste onto the outer surface of the reflective layer using a dip-molding thermoforming process. Transparent polyvinyl chloride paste is economical, and the dip-molding thermoforming process allows for the coating of transparent layers onto handles of any shape and size, making it highly practical.

[0011] A further preferred technical solution is that a UV layer is also covered and fixed on the outer side of the transparent layer. The UV layer has protective functions such as enhancing wear resistance, impact resistance, and fire retardancy, and it works well with the transparent layer to further improve the wear resistance and anti-fouling performance of the handle cover of this utility model.

[0012] A further preferred technical solution is that the UV layer is formed by curing a UV coating under ultraviolet light. The UV coating can be applied to the outer surface of the transparent layer by brushing, spraying, or other methods, and it has good compatibility with tool handles of any shape and size.

[0013] A further preferred technical solution is that the thickness of the substrate layer ranges from 1 to 2 mm, the thickness of the reflective layer ranges from 1 to 2 mm, the thickness of the transparent layer ranges from 0.5 to 1 mm, and the thickness of the UV layer ranges from 0.01 to 0.1 mm. The reasonable design of the thickness dimensions of each layer ensures the smooth fabrication and implementation of the protective handle of this utility model.

Compared with the smooth outer surface of the handle tool, the reflective layer is more firmly and durablely covered on the outer surface of the base material layer, and the transparent layer shields the reflective layer, effectively preventing peeling.

[0016] 2. The substrate layer is formed by coating and fixing polyvinyl chloride (PVC) paste onto the outer surface of the tool handle using a dip-coating thermoforming process. PVC paste is economical, and the dip-coating thermoforming process allows for the coating of the substrate layer onto handles of any shape and size, ensuring the successful fabrication and implementation of the handle cover of this invention.

[0017] 3. The polyvinyl chloride paste is a colored polyvinyl chloride paste. The substrate layer can be made in any color, and the reflective layer can be made into an intermittently distributed strip structure or a ring structure to meet the diverse color requirements of the handle cover.

[0018] 4. The reflective layer is a reflective film adhered to the outer surface of the substrate layer, or the reflective layer is formed by curing reflective paint applied to the outer surface of the substrate layer. The reflective layer can be a commercially available reflective film with adhesive backing, or it can be formed by curing reflective paint. That is, the method of covering the outer surface of the substrate layer with the reflective layer can be flexibly selected according to actual needs.

[0019] 5. The transparent layer is formed by coating and fixing a transparent polyvinyl chloride paste onto the outer surface of the reflective layer using a dip-coating thermoforming process. Transparent polyvinyl chloride paste is economical, and the dip-coating thermoforming process allows for the coating of transparent layers onto handles of any shape and size, making it highly practical.

[0020] 6. A UV layer is also fixedly coated on the outer surface of the transparent layer.

It works well with the transparent layer to further improve the wear resistance and anti-fouling performance of the handle cover of this utility model.

Specifically, the reflective layer 3 can be a plurality of rings spaced apart along the length of the tool handle 1, or it can be a strip spaced apart. Alternatively, the reflective layer 3 can be an integral cylindrical structure covering the tool handle 1.

[0027] Preferably, the substrate layer 2 is coated and fixed to the outer surface of the tool handle 1 by a polyvinyl chloride paste through a dip-molding thermoforming process.

[0031] Preferably, the transparent layer 4 is formed by coating and fixing a transparent polyvinyl chloride paste onto the outer surface of the reflective layer 3 using a dip-molding thermoforming process.

[0037] Step 2: Immerse the end of the preheated tool handle 1 that needs to have the handle sleeve installed into the colored PVC paste to a certain depth, hold for 10 seconds and then lift it out. Then place the end of the tool handle 1 that is wetted with colored PVC paste in an oven and bake it at 180°C to plasticize it. The wet colored PVC paste will then be plasticized into the substrate layer 2.

[0038] Step 3: Cut the commercially available reflective film to the preset length and width dimensions, then peel off the release paper behind the adhesive backing of the reflective film, and stick the reflective film to the outer side of the substrate layer 2 to form the reflective layer 3.
