Embodiment 1

[0012] The leather finishing agent described in this embodiment has the following components: 60 parts of acrylate, 30 parts of chloroprene, 15 parts of acrylonitrile, 15 parts of styrene propylene, 5 parts of styrene propylene, 2 parts of acrylic acid, ammonium persulfate 0.8 parts, 2 parts of sodium lauryl sulfate, 2 parts of sodium lauryl sulfate, 2 parts of polyethylene oxide, 4.0 parts of sodium bisulfate, appropriate amount of ammonia water, appropriate amount of deionized water (general value: the ammonia water is 3 parts, deionized water is 10 parts), the above are all parts by mass.

[0013] The preparation method of the above-mentioned leather finishing agent is as follows: mix deionized water, sodium lauryl sulfate, polyethylene oxide, acrylate, acrylonitrile, and styrene according to the formula, keep stirring and emulsifying for 2 hours, then raise the temperature to 60°C for 1 hour , add ammonium persulfate, continue to heat up to 70°C, continue to react for 3 ho...

Embodiment 2

[0017] The leather finishing agent described in this embodiment is different from Example 1 in that each component is composed as follows: 55 parts of acrylate, 26 parts of chloroprene, 5 parts of acrylonitrile, 5 parts of styrene acrylic, 5 parts of styrene acrylic , 1 part of acrylic acid, 0.3 parts of ammonium persulfate, 1 part of sodium lauryl sulfate, 1 part of sodium lauryl sulfate, 1 part of polyethylene oxide, 0.01 part of sodium bisulfate, appropriate amount of ammonia water, appropriate amount of deionized water, the above All are parts by mass.

[0018] The leather finishing agent described in this embodiment, production and use method are the same as embodiment 1, and use effect can be comparable with it.

Embodiment 3

[0020] The leather finishing agent described in this embodiment is different from Example 1 in that each component is composed as follows: 57 parts of acrylate, 27 parts of chloroprene, 5 parts of acrylonitrile, 10 parts of styrene acrylic, 8 parts of styrene acrylic , 1 part of acrylic acid, 0.3 parts of ammonium persulfate, 1 part of sodium lauryl sulfate, 1 part to 2 parts of sodium lauryl sulfate, 1 part of polyethylene oxide, 0.01 part of sodium bisulfate, appropriate amount of ammonia water, deionized water Appropriate amount, all of the above are parts by mass.

Abstract

The invention discloses a leather finishing agent which comprises, by mass, 55 parts to 60 parts of acrylic ester, 26 parts to 30 parts of chloroprene, 5 parts to 15 parts of acrylonitrile, 5 parts to 15 parts of allyl benzene, 5 parts to 15 parts of allyl benzene, 1 part to 2 parts of crylic acid, 0.3 part to 0.8 part of ammonium persulfate, 1 part to 2 parts of lauryl sodium sulfate, 1 part to 2 parts of lauryl sodium sulfate, 1 part to 2 parts of polyoxyethylene, sodium hydrogen sulfate, a proper amount of ammonium hydroxide and a proper amount of deionized water. The invention further discloses a production method of the leather finishing agent. The leather finishing agent is used for finishing the surface of leather, the surface of the leather can be glossy, moist and uniform in color, wounds and flaws of the leather face can be finished, meanwhile, a protective film is formed on the leather face, the waterproof performance, the wear-resisting performance and other performances of the leather are improved, and the leather finishing agent has the advantages of being better in transparency, storage stability, associativity and cold resistance, and the bonding strength of the leather finishing agent with the leather is high.

Description

technical field [0001] The invention relates to a finishing agent, especially a leather finishing agent and a production method thereof. Background technique [0002] Acrylic resin is currently the most widely used leather finishing material in the world, and its annual output accounts for 70% of the leather finishing agent. From the perspective of production cost, process and comprehensive performance, acrylic resin as a finishing material is more Other chemical materials can be said to have many advantages, but there is nothing perfect in the world, and its only defect is that it is hot, sticky and brittle, so that its use is limited by climatic conditions. Since 1987, the American Rohm and Hass company has successively developed new products, the second generation of acrylic resin (sGA), which has made a breakthrough in hot-sticky and cold-brittle. Subsequently, my country has also achieved certain results in the modified surface of acrylic materials. The finishing la...
