Leather microemulsion cleaning agent composition containing waterborne polyurethane and preparation method of leather microemulsion cleaning agent composition

Abstract

The invention provides a leather microemulsion cleaning agent composition containing waterborne polyurethane. The leather microemulsion cleaning agent composition comprises the following components: (a) 5-30 parts by weight of a multi-element nonionic surfactant; (b) 3-15 parts by weight of a leather fatting agent; (c) 1-13 parts by weight of a composite waterborne polyurethane sunscreen finishing agent; (d) 1-8 parts by weight of a cationic bactericide; (e) 0 to 0.2 part by weight of water-soluble essence; (f) to 100 parts by weight of an aqueous carrier. The composition disclosed by the invention is used as a leather cleaning agent, has the basic decontamination and stain removal effects, and also has the effects of sun protection, color protection, softness, smoothness, mildew prevention, bacteriostasis, water resistance, stain resistance and lasting fragrance retention.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a leather microemulsion cleaning agent composition containing aqueous polyurethane and a preparation method thereof. Background technique [0002] In the past, when consumers cleaned leather products, they usually used the dry cleaning method. The cleaning agent used in this method is a volatile organic solvent, which will cause irreversible damage to the softness and comfort of the leather. However, most of the water-type leather cleaning agents on the market are detergent compositions of pure surfactant systems, and the selection of surfactants in this type of systems is also mainly based on detergency, which is not suitable for biodegradation and fragrance retention. , leather damage, and human skin irritation are less considered. For example, most commercially available products contain skin-irritating fatty acid salt surfactants as detergents, and many pr...

Problems solved by technology

[0003] At present, there are few relevant reports on functional water-based leather cleaning agents in China. Patent CN102876478A reports "A Leather Cleaning Agent". The cleaning agent added with antioxidants solves the problem of leather oxidation to a certain extent, but the cleaning The agent selects a surface-active system containing strong irritating linear alkylbenzene sulfonate as the detergency, and the polyurethane resin in the system is only a common film-forming agent, and its efficacy is relatively single.

The product mentioned in the "Colored Leather Color Enhancement Cleaning Agent Composition and Its Preparation Method" reported by patent CN102732390A solves the problem of leather fading due to the addition of a darker color enhancer. The focus of care is color protection, and the application is relatively limited
