Problems solved by technology

[0004] Penetrant, a non-ionic surfactant, can be used as a penetrating aid for textile dyeing baths and finishing baths. Substances with significantly lower tension; however, because the existing penetrants are not easy to degrade, it is easy to cause environmental pollution after being discarded, and it is easy to cause the dyeing solution to stratify during the dyeing process, affecting the dyeing effect

Embodiment 1

[0014] Example 1: Easily degradable environmental protection leather penetrating agent, the parts by weight (kg) of its raw materials are: methyl methacrylate 42, triethylenediamine 5.5, n-butyl methacrylate 7.5, sodium sulfite 3, xylene sulfonic acid Sodium 6.5, Tributyl Citrate 3.5, N-Isopropylphthalimide 1.5, Hypophosphite 8.5, Modified Moss 22 and Water 58.

[0015] The preparation of the modified moss: dry and pulverize the moss, then put it into a hydrochloric acid solution with a mass fraction of 10%, stir it evenly and let it stand for 2-3 hours, filter to take the filter residue, rinse it several times with deionized water repeatedly, Put it into an aqueous solution containing 5% acrylic acid and 2.5% ammonium persulfate, and stir at a constant temperature of 85°C for 3-4h; filter the filter residue, mix it with 2 times the amount of paraffin emulsion, mix well and place it in an oven at 105°C Dry for 35min.

[0016] The penetrant of the present invention has a pH...

Abstract

The invention discloses an easily degradable and environmental friendly penetrating agent for leather. The easily degradable and environmentally friendly penetrating agent for leather is prepared from the following raw materials in parts by weight: 40-45 parts of methyl methacrylate, 5-6 parts of triethylene diamine, 7-8 parts of n-butyl methacrylate, 2-4 parts of sodium sulphite, 6-7 parts of sodium xylene sulfonate, 3-4 parts of tributyl citrate, 1-2 parts of N-isopropylphthalimide, 8-9 parts of hypophosphorous acid, 20-25 parts of modified moss and 55-60 parts of water. The easily degradable and environmentally friendly penetrating agent for leather has excellent levelling dyeing property, the obtained synthetic leather has good flexibility, toughness, glossiness and the like and is also low in toxicity, harm for environment and a human body in a using process is small, the degradability of the easily degradable and environmentally friendly penetrating agent, which is abandoned, for leather is strong, the stickness of peanut leaves can be improved by modifying the peanut leaves, the thickness of a slurry is enhanced, and the performance stability of the slurry is improved.

Description

[0001] technical field [0002] The invention relates to textile printing and dyeing technology, in particular to an easily degradable and environmentally friendly leather penetrating agent. [0003] Background technique [0004] Penetrant, a non-ionic surfactant, can be used as a penetrating aid for textile dyeing baths and finishing baths. Substances with significantly lower tension; however, because the existing penetrants are not easy to degrade, they are easy to cause environmental pollution after being discarded, and it is easy to cause the dyeing solution to stratify during the dyeing process, affecting the dyeing effect. [0005] Contents of the invention [0006] The purpose of the present invention is to provide an easily degradable environmental protection leather penetrating agent. [0007] In order to achieve the above object, the present invention adopts the following technical solutions: [0008] Easily degradable environmental protection leather pen...
