Mainly comprises the components of filler, hand feeling regulator, plasticizer and the like. Fillers can be classified into wax fillers, colloid fillers, and oil fillers, depending on their properties. The wax filler is mainly wax emulsion with different melting points, and is generally used for improving the off-board ironing property and avoiding the bonding phenomenon during stacking.
The leather off-board wax is a finishing soft wax assistant which is non-toxic, non-inflammable, strong in permeability and good in dispersibility, and can be widely applied to the surfaces of various kinds of leather. When the adhesive is applied to the surface of leather, the adhesive has good plate-separating property, avoids plate adhesion during high-temperature pressing, does not influence the adhesion between coatings, and can endow the leather with smooth, soft, plump and full hand feeling. At present, a plurality of leather products need a high-temperature pressing plate (100 ℃ to 120 ℃) in the production process, and the coating is not hardened after cooling, however, the anti-sticking effect of the wax on the market is below 90 ℃, the hand feeling is hard after application, and the wax contains organic solvents such as alkylphenol polyoxyethylene ether compounds and the like.

step two, 5 to 15 parts of emulsifier multi-branched chain heterogeneous C13Adding alcohol polyoxyethylene ether into the alkylolamide nonionic emulsifier prepared in the step one, and uniformly stirring;
and step three, adding the mixture obtained in the step two into water under the stirring condition, keeping the temperature for 0.5 to 1.0 hour at the stirring temperature of 80 to 99 ℃, and quickly cooling after the temperature is kept to obtain the leather coating soft wax auxiliary agent with high-temperature embossing plate-leaving property.
In the preparation method, the mass ratio of water, oleic acid, mono (di, tri) ethanolamine, solid wax tablets and emulsifier is (300-600): (5-25): (10-40): (25-50): (1-10).
In the third step, the water is deionized water.
The leather finishing soft wax auxiliary agent with high-temperature embossing and plate-separating performance is prepared by the preparation method.
Compared with the prior art, the invention has the beneficial effects that:
the leather finishing soft wax assistant with high-temperature embossing and plate separating performance, which is prepared by the invention, is anionic, has a pH value of 7-9 and a solid content of 6-18%, does not contain organic solvents such as alkylphenol polyoxyethylene ether compounds and the like, and is safe and environment-friendly. When the modified leather is used in a leather finishing process, the addition amount can be adjusted to be 5-8% according to the variety and style of leather finishing and coating materials, and the modified leather can be directly used or mixed with other materials after being diluted by water. The soft wax assistant can raise the temperature of the embossed plate of the coating to 110 deg.c, and has no influence on the glossiness and gloss retention of leather, softening of leather, and bending resistance of subsequent finishing, so that the treated leather has comfortable hand feeling.
Detailed Description
The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention include, but are not limited to, the scope shown in the following examples.
Example 1:
(1) under the high-temperature reaction condition of 100 ℃, 25 parts of solid wax flakes, 5 parts of oleic acid and 10 parts of mono (di, tri) ethanolamine are fully mixed, stirred and reacted for 10 minutes to obtain the alkanolamide nonionic emulsifier.
(2) To aid subsequent emulsification into a more stable emulsion, 5 parts emulsifier multi-branched isotridecanol polyoxyethylene ether was added thereto and stirred well until stirred well.
(3) The resulting mixture of (2) was added to water with stirring. Stirring at 80 ℃, keeping the temperature for 0.5 hour, and quickly cooling after the heat preservation is finished to obtain the leather finishing soft wax auxiliary agent with the required pH value of 7 and the solid content of 6 percent.
Example 2:
