Problems solved by technology

On the one hand, the currently used coating agents use organic solvents as solvents. Although this type of coating agent can quickly dry and form a film after being coated on leather release paper, a large amount of organic solvents will be volatilized during the drying process, which will pollute the work. The environment and human health are harmful; on the other hand, although the film-forming property is good, it is difficult to peel off the leather release paper after compounding with the synthetic leather base cloth, or the film layer is easily damaged during the peeling process
[0004] At present, clothing made of synthetic leather has good warmth retention, but poor elasticity, especially in the knees and elbows of the clothes, which are prone to deformation and swelling due to long wearing time, which affects the wearing aesthetics of the clothes, thus shortening the life of the clothes. lifespan of clothing

Embodiment 1

[0020] Preparation of topcoat agent: Add 3 parts of polyvinyl alcohol resin, 2 parts of propylene glycol alginate and 1 part of polyvinyl chloride paste resin to 150 parts of water, heat up to reflux state at a heating rate of 5 °C / min and mix for 30 minutes. Then add 2 parts of microcrystalline wax, 0.5 parts of N,N'-methylene bisacrylamide and 0.5 parts of sodium dodecyl diphenyl ether disulfonate, continue to reflux and keep mixing for 15 minutes, and then lower the temperature at 10°C / min Cool down to 40-50°C and mix for 30 minutes, then add 20 parts of water-based polyurethane resin, 3 parts of polyquaternium salt, 2 parts of anionic polyacrylamide and 2 parts of sodium carboxymethyl cellulose, mix well and let stand for 30 minutes, then Then heat up to reflux at a heating rate of 5°C / min and keep mixing for 15 minutes. The resulting mixture is naturally cooled to room temperature and sent to a ball mill, and finally passed through a 200-mesh sieve to obtain a top coating ...

Embodiment 2

[0028] Preparation of topcoat agent: Add 5 parts of polyvinyl alcohol resin, 2 parts of propylene glycol alginate and 1 part of polyvinyl chloride paste resin to 150 parts of water, heat up to reflux state at a heating rate of 5°C / min and mix for 30 minutes. Then add 1 part of microcrystalline wax, 0.5 part of N,N'-methylenebisacrylamide and 0.5 part of sodium dodecyl diphenyl ether disulfonate, continue to reflux and keep mixing for 15 minutes, and then cool down at 10°C / min Cool down to 40-50°C and mix for 30 minutes, then add 20 parts of water-based polyurethane resin, 3 parts of polyquaternium salt, 2 parts of anionic polyacrylamide and 2 parts of sodium carboxymethyl cellulose, mix well and let stand for 30 minutes, then Then heat up to reflux at a heating rate of 5°C / min and keep mixing for 15 minutes. The resulting mixture is naturally cooled to room temperature and sent to a ball mill, and finally passed through a 200-mesh sieve to obtain a top coating agent.

Abstract

The invention discloses a four-side elastic synthetic leather functional release paper coating material applicable to clothes, and relates to the technical field of synthetic leather processing. Face coating agent, middle coating layer and following coating agent are used as the coating material of the release paper; a film layer is formed on the release paper through synergistic effect, wherein water is used as solvent of the coating agent; the coating material is safe and toxic-free, and strong in environmental protection property; the invention can avoid the problem that the easy volatile existed in organic solvent can pollution environment and hurt human body health; meanwhile, the compositeness of the prepared film layer and a synthetic leather base cloth is good, and the film layer can easily and completely peel from the release paper; after compounding the prepared film layer and the synthetic leather base cloth, the synthetic leather has excellent elasticity, and is also featured by high intensity, good in both hydrolysis resistance and flame retardance; therefore, the coating material is applicable to process the clothes with four-side elasticity.

Description

Technical field: [0001] The invention relates to the technical field of synthetic leather processing, in particular to a release paper coating material suitable for making four-sided elastic synthetic leather for clothing. Background technique: [0002] At present, leather resources are increasingly scarce and expensive in the clothing leather market. With the development of clothing synthetic leather technology in recent years, synthetic leather is very close to genuine leather in terms of style and feel, and even surpasses genuine leather in some aspects. At the same time, due to the low price and various styles of synthetic leather clothing, synthetic leather clothing has already occupied more than half of the leather clothing market and is favored by consumers. [0003] Leather release paper, also known as transfer paper, is an indispensable carrier for transfer coating processing, which can endow synthetic leather with beautiful patterns. The coating agent is first ev...
