[0035] The invention provides the following technical solutions: a high-elasticity and low-cost adhesive plaster for football, the preparation method of which includes:
[0036] A. First use natural rubber to make the outer film layer with high elasticity;
[0037] B, prepare the mesh cloth layer with high elasticity again;
[0038] C, the outer film layer heating of preparation is fixedly bonded with the mesh cloth layer of high elasticity to make adhesive cloth base layer;
[0039] D. Paste the thermoplastic polyurethane elastic (TPU) film on both sides of the adhesive plaster base layer;
[0040] E. Heat the adhesive layer and coat it on the surface of the thermoplastic polyurethane elastic (TPU) film.
[0041] When preparing high-elasticity and low-cost tapes for football, the outer film layer with high elasticity is made of natural rubber. Natural rubber contains rubber hydrocarbons, latex, protein, fatty acids, ash, sugar and other non-rubber substances. Heat and melt...
Embodiment 1
[0045] Example 1, when preparing high-elasticity and low-cost rubber cloth for football, first adopt natural rubber to make an outer film layer with high elasticity. Natural rubber contains 90% to 93% of rubber hydrocarbons, 2% to 3% of latex, and protein 1%-3%, fatty acid 1%-2%, ash 1%-3%, sugar and other non-rubber substances 1%, heat and melt the natural rubber, then add defoamer and stir evenly, let it stand for 10-15min to dissolve the liquid The natural rubber is poured into the mold and cooled naturally.
[0046] Then prepare a mesh cloth layer with high elasticity, the mesh cloth layer with high elasticity is elastic polyester fiber, and the elastic polyester fiber is made into a grid shape, and the grid shape makes thermoplastic polyurethane elastic (TPU) film and The base layer of tape is easier to bond.
[0047] Place the highly elastic outer film layer in a heating mold and heat it at a temperature of 150-160°C until the surface softens, then place the highly elas...
Embodiment 2
[0049] Example 2, when preparing high-elasticity and low-cost rubber cloth for football, first adopt natural rubber to make an outer film layer with high elasticity. Natural rubber contains 88% to 90% of rubber hydrocarbons, 1% to 3% of latex, and protein 2%-3%, fatty acid 1.5%-2%, ash 2%-4%, sugar and other non-rubber substances 1%, heat and melt the natural rubber, then add defoamer and stir evenly, let it stand for 10-15min to dissolve the liquid The natural rubber is poured into the mold and cooled naturally.
[0050] Then prepare a mesh cloth layer with high elasticity, the mesh cloth layer with high elasticity is elastic polyester fiber, and the elastic polyester fiber is made into a grid shape, and the grid shape makes thermoplastic polyurethane elastic (TPU) film and The base layer of tape is easier to bond.
[0051]Place the highly elastic outer film layer in a heating mold and heat it at a temperature of 150-160°C until the surface softens, then place the highly ela...
