Description

Technical Field

[0001] The invention relates to the technical field of swimming pool adhesive films, and in particular to an anti-skid and aging-resistant swimming pool adhesive film and a preparation method thereof. Background Art

[0002] Pool film is a waterproof decorative material used for the inner wall of swimming pools. It has gradually become a substitute for ceramic tiles and mosaics due to its durability, easy installation and simple maintenance. This material is usually made of PVC (polyvinyl chloride), has good waterproof performance and decorative effect, and can be used not only for indoor swimming pools but also for outdoor swimming pools. However, PVC is prone to aging under long-term ultraviolet radiation, causing discoloration and embrittlement of the material, thus affecting its service life and aesthetics, limiting its application in swimming pool construction.

[0003] Existing swimming pool disinfection generally uses chlorinated disinfectants, which kill bacteria and viruses by reacting with water to produce hypochlorous acid. These substances are also corrosive to PVC, and swimmers who are exposed to chlorine-containing disinfectants for a long time may increase the risk of asthma, bronchial hyperreactivity and respiratory inflammation.

[0004] Based on this, it is urgent to develop a new swimming pool film. Summary of the invention

[0005] In view of the defects of the prior art, the present invention provides a non-slip and aging-resistant swimming pool film and a preparation method thereof.

[0006] In order to achieve the above purpose, the present invention solves the technical problem by adopting the following technical solutions:

[0011] Preferably, the average degree of polymerization of the polyvinyl chloride is 980-1080.

[0012] Preferably, the preparation of the modified polyvinyl chloride comprises the following steps:

[0013] Under a protective atmosphere, polyvinyl chloride resin powder, 2-allyl-4-methylphenol and dibenzoyl peroxide are added to a reaction kettle and stirred evenly, then the temperature is raised to 70-80°C and kept for 1-3 hours, then the temperature is raised to 110-130°C and mechanically stirred for 30 minutes to obtain a mixture, deionized water is added at a material-liquid ratio of 1:(10-30) and the mixture is reacted at 110-130°C for 4-8 hours, filtered and dried to obtain modified polyvinyl chloride.

[0014] Preferably, the added amount of the 2-allyl-4-methylphenol is 3-7wt% of the polyvinyl chloride resin powder, and the added amount of the dibenzoyl peroxide is 0.3-0.5wt% of the polyvinyl chloride resin powder.

[0015] Preferably, the preparation of the filler comprises the following steps:

[0016] S1. Add zinc oxide with a particle size of 1 μm into anhydrous ethanol and stir to disperse for 1 hour, then add vinyltrimethoxysilane solution, heat to 65-75°C and react for 4-8 hours. After the reaction is completed, cool to room temperature, wash with anhydrous ethanol, and dry to obtain modified zinc oxide.

[0017] S2. Use ultrapure water to prepare 0.6-1 mol / L silver nitrate solution and 0.8-1.2 mol / L copper nitrate solution respectively, then mix the silver nitrate solution and the copper nitrate solution in a volume ratio of 1:2, and stir at 300-500 rpm for 30 minutes to obtain a metal precursor solution.

[0018] S3. Immerse the modified zinc oxide in the metal precursor solution, stir continuously at 65-75° C. for 4-6 hours, and then dry to obtain a filler loaded with metal ions.

[0019] Preferably, the vinyltrimethoxysilane solution is prepared by mixing vinyltrimethoxysilane, anhydrous ethanol and ultrapure water in a mass ratio of (0.5-1.5):12:12.

After the injection molding is completed, the pressure is maintained at 500-70bar, and the swimming pool film is obtained through embossing, cooling, and trimming.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The invention provides a new swimming pool adhesive film, comprising modified polyvinyl chloride, filler, diisononyl cyclohexane-1,2-dicarboxylate, dioctyl adipate, paraffin oil, barium zinc liquid stabilizer, phosphite, and organic pigment; wherein the modified polyvinyl chloride is prepared by thermally decomposing dibenzoyl oxide to produce strong free radicals, followed by grafting 2-allyl-4-methylphenol, and introducing a hindered phenol structure, thereby providing an overall composite material with improved aging resistance.

[0025] At the same time, the present invention also modifies the surface of zinc oxide by organic silicon to obtain zinc oxide containing double bonds, which further improves the anti-aging effect, can also be cross-linked with the main body to form a cross-linked network structure, and improves the stability and mechanical properties of the overall material. In addition, the zinc oxide particle size is relatively large, and after the film is prepared, the surface of the overall material is uneven, thereby increasing the anti-slip property. In addition, the zinc oxide can slowly release zinc ions and synergize with the loaded metal ions to achieve a slow-release sterilization effect both indoors and under light, thereby reducing the use of chlorinated disinfectants, improving water quality safety, and reducing the maintenance cost of the swimming pool.

[0026] In addition, the preparation method of the present invention is simple and can be used for large-scale industrial production, which promotes the development of polyvinyl chloride materials and provides new ideas for swimming pool materials. DETAILED DESCRIPTION

[0067] Comparative Example 4

[0068] The difference between Comparative Example 4 and Example 1 is that the filler is replaced by an equal mass of light calcium carbonate, and the other contents are the same.

[0069] Comparative Example 5

[0070] The difference between Comparative Example 5 and Example 1 is that the graft modification of the polyvinyl chloride is different, and the others are the same.

[0071] In a nitrogen atmosphere, polyvinyl chloride resin powder (average degree of polymerization of 980-1080), methyl methacrylate, and dibenzoyl peroxide are added to a reaction kettle and stirred evenly, then heated to 60°C for 2 hours, then heated to 150°C for mechanical stirring for 30 minutes to obtain a mixture, then deionized water is added at a material-liquid ratio of 1:8 and reacted at 100°C for 6 hours, filtered and dried to obtain modified polyvinyl chloride.

[0072] Comparative Example 6

[0073] The difference between Comparative Example 6 and Example 1 is that the modified zinc oxide is different, and the other aspects are the same.

[0075] Test Example 1

[0076] The swimming pool films prepared in Examples 1-3 and Comparative Examples 1-6 were cut into 3mm×3mm×0.5mm sheets as test samples, and the performance tests were performed on the test samples according to the national standard GB / T28935-2012 "Disassembly-type swimming pools". The antibacterial test was performed according to JIS Z 2801 "2010 Antibacterial processed products - Antibacterial test methods, antibacterial effects".

[0079]

[0080]

[0081] Table 2 Test results of anti-penetration, temperature stability and light stability of swimming pool film

[0082]

[0083]

[0084] As shown in Table 1-2, compared with Comparative Examples 1-6, the swimming pool film prepared in Examples 1-3 has good mechanical properties, and the elongation at break can reach more than 200%. At the same time, it also has good anti-permeability, temperature stability and light stability, which is beneficial to the application of swimming pool film. In particular, it can be seen from Comparative Examples 3, 5 and Example 1 that the modified polyvinyl chloride can significantly improve the aging resistance of the overall material. At the same time, it can be seen from Comparative Examples 4, 6 and Example 1 that compared with inorganic fillers such as light calcium carbonate, the filler of the present invention can not only further improve the aging resistance of the overall material by modifying zinc oxide with double bonds and loading multiple metal ions, but also zinc oxide can slowly release zinc ions under light, and synergistically with other metal ions, which is beneficial to improve the antibacterial property of the overall material.

[0085] It can be seen from Comparative Examples 1-2 that only when modified polyvinyl chloride, filler, diisononyl cyclohexane-1,2-dicarboxylate, dioctyl adipate, paraffin oil, barium zinc liquid stabilizer, phosphite, organic pigment and preparation method cooperate and coordinate with each other within a certain range, the obtained swimming pool film has better performance.

[0086] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
