Abstract

A kind of coating and decorating agent for leather is by water-fast water resistance good membrane-forming agent such as poly-(methyl) acrylate of alcohol-sol-resin, the fatting agent of softening maintenance leather such as vegetable and animals oils and sulfide thereof such as peanut oil, lanolin, auxiliary agent such as polyoxyethylene castor oil, polyoxyethylene alkylation phenolic ether, dyestuff, white dyes, pearling agent, diluent ethanol, Virahol, water are formed.Often use to leather and leather goods have smooth, soft, bright, kishke feel by force, the effect of waterproof anti-chap.

Description

A kind of coating and decorating agent for leather

The present invention relates to a kind of coating and decorating agent for leather, be applicable to the maintenance of kolinsky, corium leather goods such as clothing, leather trunk, leather shoes, leather gloves, fur cap and the usefulness of covering with paint.

The leather protecting agent that existing market is sold has two kinds basically, a kind of is that finishing agent only has the painted covering with paint function of adding lustre to, as the Chinese invention patent application number is 88102840.1 to disclose a kind of multi-functional optical brightener, be used for instrument, instrument, furniture, glass, plastics, the various smooth surface wipings of leather and add lustre to, leather do not had maintenance function, its composition is based on silicone oil, with stearic acid, paraffin is auxilliary, add an amount of tween, sapn and emulsifying agent, be polymerized at a certain temperature; Another kind is a leather protection agent, only have the leather simple function, do not have the covering with paint function, a kind of leather oil is disclosed as United States Patent (USP) U.S428568.8, it accounts for 30-50% by non-drying animal oil, and the non-drying vegetables oil accounts for 20-30%, animal grease 10-20%, natural wax 5-10%, it is formulated that mineral tallow or petroleum wax account for 5-10%.

The purpose of this invention is to provide and a kind of leather has been had maintenance function, had the coating and decorating agent for leather of covering with paint, lacquer, colour wash, etc. function again.

The objective of the invention is to finish like this:

(1) good with water-fast water resistance; has the membrane-forming agent of covering with paint, lacquer, colour wash, etc. function; form one deck protective film at leather surface, they are: alcohol-sol-resin, poly-(methyl) acrylate, urethane, silicone resin and modified poly solution or emulsion, cellulose ester fiber, polyoxyethylene glycol, C each other ₁₂Above Fatty Alcohol(C12-C14 and C12-C18) (acid) and their derivative, animals and plants wax, mineral tallow, petroleum wax adopt wherein several or a kind of;

(2) have the fatting agent of softening maintenance leather function, as: animal-plant oil and hydrosulfate thereof adopt wherein several or a kind of as peanut oil, lanolin, sulfated castor oil;

(3) has the auxiliary auxiliary agent that maintains and cover with paint, lacquer, colour wash, etc. function; As polyoxyethylene castor oil, the terpolycyantoamino-formaldehyde resin of polyxyethylated alkylphenol, polyoxygenated (second) propylene fatty alcohol-ether, butanol etherification, the condenses of organic silicone oil, glycerine, hard ester acid esters, thanomin, adipic ketone, subsidiary material have dyestuff, pigment, fluorescent whitening agent, pearling agent, matting agent, use wherein several or a kind of outer adding preservative agents, spices;

(4) thinner that is used for weaker concn has: ethanol, Virahol, acetic ester, turps, sherwood oil, acetone, cellosolve, dimethyl formamide, water;

The proportioning of above-mentioned various materials is: membrane-forming agent (solid part) 5～25%, and fatting agent 0.1～10%, auxiliary agent 0.1～10%, thinner adds to 100%.

The preparation method of coating and decorating agent for leather:

(1) in 1 well still, gets polyacrylate solution amount of solid 40% in the polymeric solution of membrane-forming agent, methyl acrylate wherein, butyl acrylate, hydroxyethyl methylacrylate, their ratio is 55: 35: 10, with 10 parts of alcohol dilutions, 20 parts of the nitrocellulose solutions of adding 5%, heating 40-60 ℃, it is mixed to stir;

(2) get 2 parts of fatting agent peanut oil in 2 well stills, 0.5 part in lanolin adds 0.1 part of polyoxyethylene aliphatic alcohol ether, and 4 parts of sherwood oils add 20 parts of ethanol stirrings again and mix after 40-60 ℃ of stirring is miscible, pour into then in the 1 well still;

(3) in 3 well stills, get 1 part of auxiliary agent spirit dyestuff, with pouring into behind 10 parts of dissolve with ethanol in the 1 well still;

(4) add 10 parts of diluent ethanol at last in 1 well still, transfer to 100%, stirring mixes under 40-60 ℃ of temperature, is cooled to room temperature, filtration, packing.

Embodiment

In the batch mixing still, get 30 parts of the polyacrylic acid emulsions (solid part is 40%) of membrane-forming agent, methacrylic acid ester methyl ester wherein: butyl acrylate=35: 65,2 parts of fatting agent sulfated castor oils, 0.5 part of the terpolycyantoamino-formaldehyde resin of auxiliary agent butanol etherification, add 67.5 parts in diluent water again, heating 40-60 ℃ to stir mixes, and is cooled to room temperature, filter packing.

Coating and decorating agent for leather has covers with paint, lacquer, colour wash, etc. and maintains two kinds of functions, often uses leather and leather and fur products are had smooth, soft, bright, nature, characteristics that kishke feel is strong, and has the effect of water-fast, waterproof, anti-chap.
