Problems solved by technology

Because the hard anti-stab insole is heavy, inconvenient to use, and the performance of the adhesive is limited, if the method of directly inserting the insole is used to achieve the anti-puncture of the shoe, the surface of the anti-stab insole is relatively hard and the wearing performance will be reduced. Not good, high degree of fatigue, low adaptability to human health requirements
However, the anti-stab shoes produced by the conventional shoe-making process usually use solvent-based adhesives due to insufficient adhesion fastness, short service life and large waste of anti-stab insoles. This process has poor environmental protection and low safety. , high toxicity, high production cost and other disadvantages

Embodiment 1

[0027] Embodiment 1 of the present invention: the preparation of environment-friendly adhesive for flexible puncture-resistant shoes, first prepare the hydroxymethyl cellulose mother liquor, calculate by weight parts, mix 5 parts of hydroxymethyl cellulose and 0.1 part of antifungal agent BCM Add 100 parts of soft water, stir slowly and add 0.5 parts of potassium hydroxide, and continue to stir until the cellulose sodium is evenly dispersed and becomes a thick liquid without agglomeration, that is, the hydroxymethyl cellulose mother liquor is obtained. Take the hydroxymethyl cellulose mother liquor 6 parts for later use; prepare the aqueous dispersion of the compounding agent, put 0.15 parts of potassium hydroxide into the ball mill tank, add 3 parts of soft water to dissolve the potassium hydroxide, then add 0.3 parts of casein, 0.3 parts of diffusing agent NNO and 0.015 parts of part of borax, stir evenly, add 0.55 part of sulfur, 0.45 part of accelerator M, 0.5 part of accel...

Abstract

The invention discloses an environment-friendly adhesive for flexible anti-puncture shoes, which is prepared from natural emulsion, compounding agent water dispersion, ammonia water, hydroxymethyl cellulose mother liquid and wetting agent JFC. The product disclosed by the invention is a water-based adhesive and is used for replacing a solvent adhesive, thereby improving the safety and environmental friendliness. Because the bonding strength of the adhesive disclosed by the invention is good, a flexible anti-puncture insole and vulcanized rubber can be well bonded, and the bonding strength is not less than 2.5kN / m, thereby solving the problem that the anti-puncture insole is easy to debond; and the anti-puncture insole can be made by adopting a disposable double-sided swabbing process, thus the efficiency is high, the quality is good, and the product percent of pass is high. In the formula, the compounding agent water dispersion adopts an accelerator M (2-mercaptobenzothiazole), accelerator TMTD (tetramethylthiuram disulfide) and sulfur vulcanization combined system, thereby improving the internal performance of a sulfide; and the hydroxymethyl cellulose and the wetting agent JFC are used together, thereby improving the bonding strength of the water-based adhesive and the anti-puncture insole as well as the vulcanized rubber.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to an environment-friendly adhesive for flexible anti-puncture shoes and a preparation method thereof. Background technique [0002] At present, the quality of stab-resistant insoles meets the requirements of GB12017-1999 special technical standards. It has strong applicability, great promotion and application value, and significant social and economic benefits. Because the hard anti-stab insole is heavy, inconvenient to use, and the performance of the adhesive is limited, if the method of directly inserting the insole is used to achieve the anti-puncture of the shoe, the surface of the anti-stab insole is relatively hard and the wearing performance will be reduced. Not good, the degree of fatigue is high, and the adaptability to human health requirements is low. However, the anti-stab shoes produced by the conventional shoe-making process usually use solvent-based ad...
