Abstract
Production of filled foaming leather retanning agent is carried out by reacting polyglycol with oleic acid and maleic anhydride to obtain maleic polyglycol mono-oleate, polymerization reacting maleic polyglycol mono-oleate with propenyl-sulfosalt, acrylic amide and vinyl cyanide to obtain the final product. It touches soft and has excellent fallibility.
Description
Technical field
The present invention relates to a kind of preparation method of ethylene monomer copolymer type leather retanning agent, particularly a kind of preparation method of filling-foam leather composite tanning agent.
Background technology
China is the center that world's leather is produced and processed now, is a large amount of foreign exchange of national extra earning and increases millions of job opportunities every year.The leather chemicals that in the leather production process, needs hundreds of kinds, wherein leather composite tanning agent has the title of " Golden Touch " in leather production, the retanning agent of excellent performance can change the style of leather, the quality scale of raising leather, increases the added value and the economic benefit of leather significantly.Select filling properties good and can make to use and remove from office that the filling-foam leather composite tanning agent of feel as the soft sponge is arranged is the focus studied of people and the urgent expectation of leather-making enterprises always.It is poor that the selection fillibility of retanning agent well just can be dwindled the position of whole leather, improves the utilization ratio of leather; The foaming sense is exactly by force softness and springiness, and its effect is to improve the quality scale of leather and the value of use.At present, also there is not to satisfy the filling-foam leather composite tanning agent of production requirement in the leather production both at home and abroad.In actual production, filling-foam leather often will lean on experienced leather technology personnel to rely on the synergy of relevant weighting agent, retanning agent and fatting agent can reach more satisfactory effect, also makes leather processing technology and process complicated.Therefore, press for the outstanding filling-foam leather composite tanning agent of a kind of performance, make the production technique of filling-foam leather oversimplify in leather production.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of filling-foam leather composite tanning agent, when the retanning agent that makes according to preparation method of the present invention is applied to leather, it is simple to have application art, effect is remarkable, make the application leather have the fillibility of selection and reach the sense of softish sponge well, can improve the style of leather significantly.
For achieving the above object, the preparation method that the present invention adopts is:
The preparation of maleic acid polyethylene glycol monooleate: polyoxyethylene glycol-400 and oleic acid are added reactor reaction 1.5-2.0 hour 80-85 ℃ the time, add MALEIC ANHYDRIDE again and continued insulation reaction 1.0-1.5 hour, obtain the maleic acid polyethylene glycol monooleate, the mass ratio of said polyoxyethylene glycol-400, oleic acid and MALEIC ANHYDRIDE is 10: 7: 2.4;
The preparation of filling-foam leather composite tanning agent: with the maleic acid polyethylene glycol monooleate, propene sulfonic acid salt, acrylamide and vinyl cyanide were by 12.5: 1: 2: 0.5 mass ratio is mixed and made into mix monomer, adding mass fraction then in reactor is the pure water of 25-30 part, slowly adding mass parts when water temperature is 70-75 ℃ respectively is 16 parts mix monomer and 20 parts ammonium persulfate aqueous solution, ammonium persulphate massfraction 0.75% in the said ammonium persulfate aqueous solution, the reinforced time is 0.5-1.0 hour, reinforced finish the back in 80 ℃-85 ℃ insulation reaction 2.0-2.5 hour, be that 30% sodium hydroxide solution adjusting pH value is that 6.0-6.5 gets final product with massfraction at last.
The present invention prepares filling-foam leather composite tanning agent by the copolymerization of maleic acid polyethylene glycol monooleate and propene sulfonic acid salt, acrylamide and vinyl cyanide, with the filling of retanning agent and fatting agent and frothing function by the feature functionality base in the molecular chain and side group and leather fiber be used for realize.The synthesis technique uniqueness of this filling-foam leather composite tanning agent, effect is remarkable.
