The preparation method of anti-static type leather bleeding agent, 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 urea by weight, be heated to molten condition, then add pentaerythrite, triethanolamine, polyvinylpyrrolidone, abundant stirring 10-15 minute, until dissolve completely, is placed to room temperature, pour in the water of splendid attire weight portion half amount, fully stir 5-10 minute, for subsequent use;

(3) alkylphenol polyoxyethylene is taken by weight, add in the water of residue half amount, be uniformly mixed, then with the modification moss of step (1) and the standby material of step (2), other residue constitutive material is added again wherein after mixing, be uniformly mixed 20-30 minute, regulate Ph to 5-7 after cooling, to obtain final product.

Beneficial effect of the present invention:

Bleeding agent of the present invention has good frictional behavior, abrasion performance; The leather made is except the function with conventional leather, utilize the performance of triethanolamine and quaternary surfactant, the anti-static electrification of leather can be increased significantly, and coating performance is stablized, modification moss of the present invention effectively can improve the combination property of bleeding agent simultaneously, levelling excellent performance, obviously can increase the permeance property of leather dye.
