Abstract
The invention discloses a leather dye uniformly dyeing penetrating agent and a preparation method thereof. The leather dye uniformly dyeing penetrating agent comprises the following components in part by weight: 0 to 100 parts of sodium lignin sulfonate, 50 to 100 parts of polyethylene polyamine, 1 to 5 parts of sodium hexametahposphate, 40 to 100 parts of sodium sulfite, 0 to 100 parts of vegetable tannin extract and 300 to 400 parts of water. The leather dye uniformly dyeing penetrating agent simultaneously has functions of a dye levelling agent and a penetrating agent, and has high uniformly dyeing performance to ensure that the surface of treated leather has uniform and bright colors; and the leather dye uniformly dyeing penetrating agent can obviously increase the permeability of a leather dye, shorten the operating time of a dyeing process, promote the absorption rate of the dye, and reduce the used amount of the dye.
Description
Technical field
The present invention relates to a kind of leather dye uniformly dyeing agent and bleeding agent.
Technical background
In the dyeing course of leather, the dispersion of dyestuff and infiltration are the two large problems of puzzlement manufacturer always.Dyestuff dispersed bad is easy to cause leather surface dyeing uneven, forms " flower face "; And the infiltration of dyestuff is bad, and leather is not good to the absorption rate of dyestuff, and dyestuff only rests on the surface, can't imbue.
At present, on market, various printing and dyeing assistants are a lot, and quality is uneven, perhaps put undue emphasis on dispersiveness and ignore permeability, perhaps only a certain type or a certain dyestuff played a role.Such as Chinese patent CN1081731 discloses a kind of high-efficient level-dyeing fixing and hyperchromicity agent for leather, can improve colorfastness, color depth, vividness etc., but it only try out in the handled leather of acrylic resin retanning agent, range of application is restricted.
Summary of the invention
The purpose of this invention is to provide a kind of leather dye uniformly dyeing penetrating agent and preparation method thereof, solve problems of the prior art.
Leather dye uniformly dyeing agent of the present invention and bleeding agent, its parts by weight are composed as follows:
0～100 part of sodium lignin sulfonate
Polyethylene polyamine 50～100
Calgon 1～5
Sodium sulfite 40～100
Tannin extract 0～100
Water 300～400
Described polyethylene polyamine is the mixture of ethylenediamine, diethanol amine, dimethylamine and monomethyl amine, preferably the mixture of equimolar ratio;
Described tannin extract is commercially available chestnut extract, can adopt Qinhuangdao, Hebei province sansan tannin extract Co., Ltd product;
The product that obtains, outward appearance are brown color or yellow green powder, and pH value (10% aqueous solution) 〉=7 is preferably 7.5～8.0.
The preparation method of described leather dye uniformly dyeing agent and bleeding agent comprises the steps:
With the first water dissolving of sodium lignin sulfonate and tannin extract, then add successively polyethylene polyamine, sodium sulfite and calgon, 110～120 ℃, pressure are under 0.17～0.3Mpa, reacted 1～12 hour, then dry, obtain product, the preferred spray drying that adopts obtains final products;
Leather dye uniformly dyeing penetrating agent of the present invention has the function of dyestuff dye leveller and bleeding agent simultaneously, and the levelling excellent performance makes the leather surface color homogeneous after processing, and is bright-coloured; Can obviously increase the permeance property of leather dye, shorten the operating time of dyeing, promote the absorptivity of dyestuff, reduce the consumption of dyestuff.
The specific embodiment
Embodiment 1
The fatting agent of described raising strength of leather, it is composed as follows, is weight portion:

With the first water dissolving of sodium lignin sulfonate, then add successively polyethylene polyamine, sodium sulfite and calgon to mix, reaction system is warming up to 120 ℃, pressure 0.17Mpa, reacted 3.5 hours, get final products after the liquiform product of gained is spray-dried.
The product that obtains, outward appearance are brown color or yellow green powder, and pH value (10% aqueous solution) is 7.5.
According to following technique, example one product is tested, ox-hide is adopted in test:
Detect after completing
The water of 1, discharging is limpider, substantially residual without dyestuff, and dyestuff absorbs fully;
2, observe the leather surface even dyeing, without obvious aberration;
3, contrast is found, as not adding example 1 product, reach same Color, the dyestuff addition will increase by 1%;
Embodiment 2
The fatting agent of described raising strength of leather, it is composed as follows, is weight portion:
Tannin extract 100
Polyethylene polyamine 50
Calgon 5
Sodium sulfite 100
Water 350.
Polyethylene polyamine is the mixture of the equimolar ratio of ethylenediamine, diethanol amine, dimethylamine and monomethyl amine;
Tannin extract is commercially available chestnut extract.
The preparation method is:
With the first water dissolving of tannin extract, then add successively polyethylene polyamine, sodium sulfite and calgon to mix, reaction system is warming up to 120 ℃, pressure 0.18Mpa, react 5 hours, must final products after the liquiform product of gained is spray-dried.
The product that obtains, outward appearance are brown color or yellow green powder, pH value (10% aqueous solution) 8.0.
According to following technique, example one product is tested, sheepskin is adopted in test:
Detect after completing
The water of 1, discharging is limpider, substantially residual without dyestuff, and dyestuff absorbs fully;
2, observe the leather surface even dyeing, without obvious aberration;
3, contrast is found, as not adding example 2 products, reach same Color, the dyestuff addition will increase by 0.5%;
