AI Technical Summary

Problems solved by technology

The main reason is that general flame retardant materials are used in a large amount and are poor in environmental protection. When used in leather crafts, the leather will harden and lose its softness and plumpness. Moreover, it will produce some serious side effects while exerting the flame retardant effect.

Abstract

The invention relates to the technical field of leather manufacturing technologies and provides a production method for waterproof and flame-retardant shoe upper leather. Chromium-zirconium-aluminum and zirconium-aluminum-titanium which have the flame-retardant property serve as a tanning agent and a retanning agent to conduct tanning and retanning; the retanning agent, a neutralizing agent and afatting agent which have the waterproof property are selected to enable the leather to have the waterproof property; an environment-friendly-type flame retardant is selected to enable the leather to have the flame-retardant property; and modified graphene-based acrylic resin and modified graphene-based polyurethane are added in filling and coating materials to serve as waterproof and flame-retardant enhancers to enable the leather to have the good waterproof and flame-retardant effects. According to the production method, under the precondition that natural leather has the excellent quality, the environment-friendly and flame-retardant effects of the leather can be achieved, the dosage of the flame retardant is reduced, the production cost is reduced, and the production method is suitablefor batch production and application.

Description

technical field [0001] The invention relates to the technical field of tanning technology, in particular to a production method of waterproof and flame-retardant shoe upper leather. Background technique [0002] The ecological, functional, fashionable and high-quality development of natural leather has gradually become a trend. As far as the functionalization of natural leather and its products is concerned, the waterproof and flame-retardant properties of leather products have become the focus of current research and application, and the proportion of waterproof and flame-retardant leather in the entire natural leather terminal market is gradually increasing. . [0003] The research and application of natural leather waterproofing agents are relatively mature, and have been applied to a certain extent in the current leather industry, especially the application of waterproof oils has been very extensive. Since natural leather needs to have good sensory properties and physi...
