Description

Technical Field

[0001] This utility model relates to the field of dust-free roll film technology, specifically to a scratch-resistant dust-free roll film layer structure. Background Technology

[0002] With the continuous advancement of technology and the increasing sophistication of industrial production, many fields have set ever higher requirements for packaging materials. In industries such as electronics, optics, and medicine, products have extremely stringent requirements for environmental cleanliness. Ordinary packaging materials are insufficient to meet these requirements, such as being dust-free and free of impurities. Traditional roll film easily absorbs dust, particles, and other impurities during production, storage, and use, which can contaminate precision products and affect their quality and performance. Therefore, dust-free roll film has emerged to meet the special packaging material needs of these high-end fields.

[0003] Modern cleanroom roll film has poor scratch resistance. Also, if the roll film is wound too far off the roller during use, the adhesive lacks protection and is easily contaminated with dust, affecting its use next time.

[0004] To address the aforementioned issues, a scratch-resistant, dust-free roll film layer structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a scratch-resistant, dust-free roll film layer structure, which solves the problems in the background technology that the current dust-free roll film has poor scratch resistance, and that if the roll film is wound out of the roll roller too much during use, the adhesive lacks protection and is easily contaminated with dust, affecting the next use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant, dust-free roll film layer structure, comprising a base layer, an antistatic coating on the outer side of the base layer, a scratch-resistant coating on the outer side of the antistatic coating, an adhesive layer on the inner side of the base layer, a release layer on one side of the adhesive layer, and a protective layer on one side of the release layer. The scratch-resistant coating, antistatic coating, base layer, and adhesive layer are layered and connected, and are located on the outer side with equidistant breaks. The release layer and protective layer are layered and connected, and are located on the inner side with equidistant breaks. The positions of the breaks on the inner and outer sides are different.

[0007] Preferably, a roller is provided on the inner side of the protective layer.

[0008] Preferably, the scratch-resistant coating is a resin containing organosilicon and polyurethane, mixed with wear-resistant filler silica.

[0009] Preferably, the antistatic coating is made of polyether ester, a polymer material, with added antistatic agents.

[0010] Preferably, the base layer is a polypropylene plastic film.

[0011] Preferably, the adhesive layer is an acrylic pressure-sensitive adhesive.

[0012] Preferably, the release layer is an organosilicon-modified coating.

[0013] Preferably, the protective layer is a biaxially oriented polypropylene film.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides a scratch-resistant dust-free roll film layer structure, which is set up in layers with an outer scratch-resistant coating on the base layer and an inner protective layer. The scratch-resistant coating and anti-static coating on the outer side of the base layer are used to prevent static electricity and improve the scratch resistance of the roll film, respectively. The adhesive layer improves the adhesion of the roll film. The release layer protects the adhesive layer and maintains the flatness of the adhesive layer. The protective layer has good mechanical strength and protects the base layer to prevent it from being bent before use. This solves the problem of poor scratch resistance and easy bending of current dust-free roll films.

[0016] 2. The present invention provides a scratch-resistant dust-free roll film layer structure. By setting the roll film with layered point breaks, the point breaks on the inner and outer sides are opened at different positions. After the release layer and protective layer are removed, the adhesive layer protrudes on one side, so that the outer end of the roll film can be adhered, maintaining the seal and not affecting the next use. This solves the problem that if the area of ​​the current dust-free roll film that is wound out of the roll roller is too large, the adhesive lacks protection and is easily contaminated with dust, affecting the next use.

The scratch-resistant coating 1, the antistatic coating 2, the base layer 3, and the adhesive layer 4 are connected in layers on the outer side, with equidistant breaks 7. The release layer 5 and the protective layer 6 are connected in layers on the inner side, with equidistant breaks 7. The positions of the breaks 7 on the inner and outer sides are different.

[0025] Specifically, the scratch-resistant coating 1 and antistatic coating 2 on the outer side of the base layer 3 are used for antistatic purposes and to improve the scratch resistance of the roll film, respectively. The adhesive layer 4 is set to improve the adhesive performance of the roll film. The release layer 5 protects the adhesive layer 4 and maintains the flatness of the adhesive layer 4. The protective layer 6 has good mechanical strength and protects the base layer 3 to prevent it from being bent before use. The separation of the inner and outer sides of the break point 7 allows the adhesive layer 4 to protrude on one side after the release layer 5 and the protective layer 6 are removed, so that the outer end of the roll film can be adhered, maintaining the seal and not affecting the next use.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example 1:

[0028] Combination Figures 2-4 The scratch-resistant coating 1 is a resin containing silicone and polyurethane, mixed with wear-resistant filler silica. The scratch-resistant coating 1 improves the hardness and wear resistance of the film surface, effectively preventing scratches and abrasions, protecting the internal structure and printed patterns of the film, while maintaining good transparency and not affecting the visual effect of the film.

[0029] The antistatic coating 2 is made of polyether ester, a high-molecular-weight material, with added antistatic agents. Polyether ester has antistatic properties. The antistatic coating 2 prevents static electricity from being generated on the surface of the roll film, avoids the adsorption of dust and impurities due to static electricity, keeps the roll film in a dust-free state, and also reduces the damage of static electricity to products and equipment, improving safety in the production process.

[0030] Base layer 3 is a polypropylene plastic film. Base layer 3 provides the film roll with basic physical properties such as strength, flexibility and dimensional stability. It is the supporting structure of the film roll and can withstand a certain amount of tension and pressure, ensuring that the film roll will not easily break or deform during use.

[0031] Adhesive layer 4 is an acrylic pressure-sensitive adhesive. It is polymerized from acrylic monomers and has good adhesion, transparency and water resistance. It adheres firmly and leaves no residue after removal.

[0032] Example 2:

[0033] Combination Figures 2-4 Release layer 5 is a silicone-modified coating. Release layer 5 is used to protect adhesive layer 4 and can be peeled off during use.

[0034] The protective layer 6 is a biaxially oriented polypropylene film. It has high transparency, good mechanical strength, wear resistance, strong chemical corrosion resistance, good rigidity and stiffness, stable chemical properties, and is non-toxic and odorless. It provides good protection for the roll film and can effectively prevent dust, moisture and other substances from corroding the roll film.

[0035] A roller 8 is provided on the inner side of the protective layer 6. The roller 8 is used to support the film roll and prevent the film roll from bending too much.
