Abstract

The invention relates to a water-borne wax-emulsion shoe polish finishing agent based on anionic polyurethane modified oxidized wax and a preparation method of the water-borne wax-emulsion shoe polish finishing agent. The water-borne wax-emulsion shoe polish finishing agent comprises polyurethane modified oxidized wax emulsion, coloring agent, wetting agent, defoaming foam inhibitor, rheological auxiliaries and anti-mildew bactericide. The preparation method includes: sufficiently grinding the coloring agent, the wetting agent and the polyurethane modified oxidized wax according to the mass of the components of the shoe polish finishing agent, stirring and dispersing for 10-40 minutes at the rotation speed of 2000-4000r / minute, lowering the rotation speed to 400-500r / minute, sequentially adding the defoaming foam inhibitor, the anti-mildew bactericide and the rheological auxiliaries, and continuing stirring for 10-20 minutes to obtain the water-borne wax-emulsion shoe polish finishing agent. The water-borne wax-emulsion shoe polish finishing agent is safe, environmentally friendly, nontoxic during use, free of pollution, less prone to combustion, free of offensive smell, good in storage stability, good in adhesive force, excellent in weather resistance and durability, excellent in scrub resistance and waterproof performance, widely applicable to the finishing and maintenance of leather shoes, leather bags, leather coats and the like, and extremely high in environment protection benefit, social benefit and economic benefit.

Description

technical field [0001] The invention relates to a water-based shoe polish finishing agent, in particular to a water-based wax emulsion shoe polish finishing agent applied to leather shoes based on anionic polyurethane modified oxidized wax and a preparation method thereof. Background technique [0002] Shoe polish finishing agent is a fine chemical that modifies and beautifies leather. Its main functions are to increase the appearance of leather, improve the performance of leather, improve the durability of leather products and prolong the service life. my country is the world's largest producer of leather and its products. The production of leather shoes accounts for 60% of the global output, and the total industrial output value exceeds one trillion yuan. The traditional shoe polish finishing agent is mainly composed of natural wax, synthetic wax, turpentine, solvent, etc., and its formula contains a large amount of solvent, which has a pungent smell and poor oily effect, ...
