Problems solved by technology

At present, the method of making waterproof vamps is to use the method of sewing first and then applying waterproof glue, and the waterproof glue must be sewn into the vamp before coating, which is inconvenient to apply, and the amount of existing waterproof glue is relatively large. Large, the seams of waterproof pieces need to be coated with waterproof glue 2 to 3 times to achieve waterproof effect, which means high production cost and waste of man-hours

Embodiment 1

[0011] Embodiment 1, the percentage by weight of the hot-melt adhesive is 20%, the percentage by weight of the solvent is 80%, wherein the hot-melt adhesive is thermoplastic polyurethane particles, the particle size of the thermoplastic polyurethane particles is 50 μm, and the solvent is ethyl acetate.

Embodiment 2

[0012] Embodiment 2, the percentage by weight of the hot-melt adhesive is 25%, the percentage by weight of the solvent is 75%, wherein the hot-melt adhesive is thermoplastic polyurethane particles, the particle size of the thermoplastic polyurethane particles is 60 μm, and the solvent is acetone.

[0013] The process of the present invention is: prepare the materials according to the ratio, add the hot-melt glue into the solvent and stir evenly, if it cannot be stirred evenly, the method of aiding dissolution can be used to stir after standing still for 48 hours, using heating or pressurizing The method is stirred; After stirring evenly, promptly finish the production process of the present invention.

[0014] The present invention is applicable to the production method of waterproof shoe uppers which are coated with waterproof glue first and then sewn. Since the reactivated melting point of the present invention is 45°C to 110°C, it can be activated and filled with pinholes an...

Abstract

The invention relates to the adhesive technique field, in particular to a water proof adhesive, which consists of hot melt glue and solvent; the weight percentage of the hot melt glue is 15 to 25 percent and the solvent is 85 to 75 percent; the hot melt glue is polyurethane particle with thermoplastic; the particle size is 0 to 1000Mum; the solvent is one of the materials of ethyl acetate, acetone, N, N-dimethyl formamide, ketone, methyl ethyl ketone, toluene, tetrahydrofuran and cyclohexanone; the invention is liquid, easy to stick and coat, is suitable for a production method of sewing after coating the water-proof adhesive of water-proof shoes surface; in addition, the adhesive coating needs only one time; therefore, adhesive consumption is small, use is convenient and production cost is saved.

Description

Technical field: [0001] The invention relates to the technical field of glue, in particular to a waterproof glue. Background technique: [0002] In the production process of waterproof shoes, the joints between the soles and uppers of waterproof shoes are very important, especially the joints of waterproof cutting pieces in the waterproof uppers. At present, the method of making waterproof vamps is to use the method of sewing first and then applying waterproof glue, and the waterproof glue must be sewn into the vamp before coating, which is inconvenient to apply, and the amount of existing waterproof glue is relatively large. Large, the seams of the waterproof cut pieces need to be coated with waterproof glue 2 to 3 times to achieve the waterproof effect, that is, the production cost is high and man-hours are wasted. Invention content: [0003] The object of the present invention is to provide a waterproof adhesive with good waterproof performance, strong adhesion and ...
