The preparation method of the synthetic leather bleeding agent of even dyeing, comprises the following steps:

(1) preparation of modification moss: moss is shone dry grinding, then the hydrochloric acid solution that mass fraction is 10% is put into, 2-3h is left standstill after stirring, cross leaching filter residue, repeatedly rinse several times with deionized water, put in the aqueous solution containing 4-6% acrylic acid, 2-3% ammonium persulfate again, stir 3-4h at 80-90 DEG C of constant temperature; Cross leaching filter residue, then mix with the paraffin wax emulsions of 2-3 times amount, after mixing, be placed on 100-110 DEG C of oven dry 30-40min in baking oven;

(2) take retinal by weight, add in reactor, be filled with nitrogen and be warming up to 200-250 DEG C, then add sodium metasilicate, isooctanol phosphide and castor oil polyoxyethylene ether, insulation reaction 3-4h, filters after reaction immediately, then by for subsequent use after filtrate cooling;

(3) take other by the weight portion of constitutive material and remain each raw material, first isomeric alcohol polyethenoxy ether is added to the water, is uniformly mixed, then add the filtrate of step (2), be heated to 150-160 DEG C, stir 20-30 minute, then add other residue constitutive material, be heated to 80-90 DEG C, be uniformly mixed 2-4 hour, finally regulate Ph to neutral, after being cooled to normal temperature, filtration, blowing.

Beneficial effect of the present invention:

Bleeding agent of the present invention is made up of surfactant, silane coupler, ethers and water, improves speed and uniformity that fabric absorbs dye liquor; Improve the dispersing uniformity of dyestuff; Reduce the reunion of dye granule, realize the raising of dyeing uniformity, preparation method of the present invention is simple, soluble in water, has good infiltration, emulsification and washing performance.
