preparation example Construction

[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...

Abstract

The invention discloses a high-elasticity low-cost adhesive tape for footballs, wherein the high-elasticity low-cost adhesive tape for footballs comprises an outer film layer, a screen cloth layer, thermoplastic polyurethane elastic (TPU) films and adhesive layers. When the elastic adhesive tape is manufactured, A, natural rubber is firstly used for manufacturing the high-elasticity outer film layer; B, the screen cloth layer with high elasticity is prepared; C, the prepared outer film layer is heated and then fixedly bonded with the high-elasticity screen cloth layer to form an adhesive tapebase layer; D, the thermoplastic polyurethane elastic (TPU) films are bonded to the surfaces of two sides of the adhesive tape base layer; and E, the adhesive layers are heated, and the surfaces of the thermoplastic polyurethane elastic (TPU) films are coated with the adhesive layers. The adhesive tape has the advantages of good elasticity, high viscosity, environmental protection, aging resistance and low production cost.

Description

technical field [0001] The invention relates to the technical field of high-elasticity and low-cost adhesive tape for football, in particular to a high-elasticity and low-cost adhesive tape for football. Background technique [0002] Football, known as "the world's number one sport", is the most influential individual sport in the global sports world. [0003] During the game, try to shoot the football into the opponent's goal. Every time you score a goal, you can get one point. When the game is over, the team with the most points wins. If the score is the same within the specified time of the game, it depends on the rules of the game, and the competition can be divided in the form of drawing lots, rematch in overtime or penalty kicks (12 yards). [0004] In football matches, except for the goalkeeper who can use his hands to touch the football in his own penalty area, each player on the field can only use other parts of his body other than his hands to control the football...
