Problems solved by technology

The adhesion strength of natural latex is not ideal, and sometimes it cannot reach the national standard of 2.5kg / cm2. Natural latex contains ammonia water as a preservative, which has a pungent smell, and most of the vulcanization aids added to natural latex are Solid particles must be emulsified with a ball mill or agitator for 48 hours before they can be added to the latex, which results in a long cycle, short use time, and unstable performance
Using oily vulcanizate, its VOC does not meet the standard, does not meet the national environmental protection requirements, and the adhesion of the shoe surface is not ideal.

Embodiment 1

[0029] Step 1, taking natural latex by weight is 100 parts, followed by weighing according to the percentage by weight of natural latex: the ratio of emulsifier is added as 0.5% of natural latex, that is, emulsifier is 0.5 part, the ratio of water-based rosin terpene resin 6% of natural latex, that is, 6 parts of water-based rosin terpene resin and the addition ratio of 1% of natural latex, that is, 1 part of new ammonia-free preservative;

[0030] Step 2, add 100 parts of natural latex into the reaction kettle and add to 20-25°C, turn on the built-in mixer in the reaction kettle and stir at a stirring speed of 100-200rpm / min, and slowly add emulsifiers to the reaction kettle in turn 0.5 parts, water-based rosin terpene resin is 6 parts, and kept at a working temperature of 20-25 ° C, stirred at a stirring speed of 100-200 rpm / min and continued for 30-35 minutes to obtain a mixed solution A;

[0031] Step 3: Slowly add 1 part of the new ammonia-free preservative to the mixed l...

Embodiment 2

[0034] Step 1, taking natural latex by weight is 100 parts, followed by weighing according to the percentage by weight of natural latex: the ratio of emulsifier is added as 1% of natural latex, that is, emulsifier is 1 part, the ratio of water-based rosin terpene resin 8% of natural latex, that is, 8 parts of water-based rosin terpene resin and the addition ratio of 1.5% of natural latex, that is, 1.5 parts of new ammonia-free preservative;

[0035] Step 2, add 100 parts of natural latex into the reaction kettle and add to 20-25°C, turn on the built-in mixer in the reaction kettle and stir at a stirring speed of 100-200rpm / min, and slowly add emulsifiers to the reaction kettle in turn 1 part, 8 parts of water-based rosin terpene resin, and kept at a working temperature of 20-25 ° C, stirred at a stirring speed of 100-200 rpm / min and continued for 30-35 minutes to obtain a mixed solution A;

Abstract

The invention relates to the technical field of water-based vulcanized adhesive for shoes, in particular to a method of water-based vulcanized adhesive for shoes. The method comprises the following steps: S1, selecting raw materials of the water-based vulcanized adhesive for shoes: natural latex, an emulsifier, water-based rosin terpene resin, a thickening agent, a stabilizer, a novel ammonia-freepreservative and water-based polyurethane resin; and S2, after selecting the raw materials of the water-based vulcanized adhesive for shoes, weighing 100 parts of natural latex according to parts byweight. Through design, the water-based polyurethane resin has the characteristics of strong cohesion and adhesive power after being solidified by adding a solidifying agent and no pollution, the natural latex has the characteristics of high initial adhesion property and good film formation, the natural latex takes ammonia water as preservative, the ammonia water reacts with a water-based isocyanate solidifying agent added by the water-based polyurethane strongly, ammonia in the natural latex is removed, aids are added to physically blend the water-based polyurethane and the improved natural latex, and a stable water-based vulcanized adhesive product with high mechanical water property is obtained.

Description

technical field [0001] The invention relates to the technical field of water-based vulcanized rubber for shoes, in particular to a method for water-based vulcanized rubber for shoes. Background technique [0002] At present, most vulcanized canvas shoe factories generally use two kinds of glue, natural latex and oily vulcanized rubber. The adhesion strength of natural latex is not ideal, and sometimes it cannot reach the national standard of 2.5kg / cm2. Natural latex contains ammonia water as a preservative, which has a pungent smell, and most of the vulcanization aids added to natural latex are Solid particles must be emulsified with a ball mill or agitator for 48 hours before they can be added to the latex, which results in a long cycle, short use time and unstable performance. Using oily vulcanizate, its VOC does not meet the standard, does not meet the national environmental protection requirements, and the adhesion of the shoe surface is not ideal. [0003] In summary,...
