Leather water-proof curing agent and preparing method thereof

Abstract

The invention discloses a leather water-proof curing agent and a preparing method thereof. The water-proof curing agent comprises a solvent, emulsifiers, a water repellent, a brightness nourishing agent, stearic acid, wax, KOH (potassium hydroxide), a mould-proof bactericide, other auxiliary materials and deionized water, wherein the solvent is one or two of solvent oil 120# and solvent oil 200#; two or three of glycerin monostearate, ceteareth-2 and ceteareth-21 are used as the emulsifiers; one or several of the carnauba wax, lignite wax, ethylene oxide wax and paraffin are used as the wax; one or several of iodopropynyl butylcarbamate, 5-chloro-dimethyl-4- isothiazolin-3-ketone and dimethyl-4-isothiazolin-3-ketone are used as the mould-proof bactericide. A unique preparing technology is matched. The water-proof curing agent has efficient and lasting water-proof effect and can well resist oil stains and dust, and the comprehensive curing performance and the water-proof performance are obviously improved.

Description

technical field [0001] The invention relates to a leather care product and a manufacturing method thereof, in particular to a leather waterproof curing agent and a manufacturing method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, leather products are more favored by people. Following the advancement of science and technology, people also put forward higher requirements for leather care. Leather care products are basically divided into three types in terms of dosage forms, one. Emulsion-type care agent is the most common in the market, and it is also the most used one. Emulsion-type care agent is mainly composed of wax, water and shellac oil. It is divided into two types: oil-in-water type and water-in-oil type. Those are common. 2. The oil-type care agent is mainly composed of wax and oil, and does not contain water; therefore, it is more waterproof than the emulsion type, but if the oil-type care a...

Problems solved by technology

2. The oil-type care agent is mainly composed of wax and oil, and does not contain water; therefore, it is more waterproof than the emulsion type, but if the oil-type care agent is used for a long time, the color of the leather will become lighter

3. The liquid care agent is mainly made of emulsified wax, resin and water; this kind of care agent does not need to be wiped, and it is applied on the leather to form a light film on the surface of the leather to make the leather bright, and its maintenance of the leather is poor. , also reduces the breathability of the leather

Oil-type care agent is the earliest care product, like shoe polish waxing in the past, oil-type care agent has high oil content, and the oil component is not volatile, not easy to dry, easy to attract dust, easy to stain clothes, gradually people use it Fewer and fewer, now the most used is the emulsion type care agent, the water resistance of the emulsion type care agent is not as good as the oil type care agent, as we all know, water is the first killer of leather, when the genuine leather meets water, it will make the water into the leather The oil in the leather will be hydrolyzed, thereby destroying the oil film between the fibers inside the leather. The oil film in the leather will be lost with the volatilization of water, so the fibers between the leather will lose their lubricity and bond together. The friction will increase, slowly causing the leather to lose its elasticity and luster, and the leather will harden, become brittle, dry, and even crack
