Leather dressing treatment composite material and preparation method thereof

Abstract

The invention discloses a leather dressing treatment composite material and a preparation method thereof. The leather dressing treatment composite material is prepared from the following raw materials in parts by weight: 8-20 parts of graining paste, 70-150 parts of brightening agent, 20-40 parts of slip agent, 10-30 parts of feeling agent, 0.1-0.3 part of wetting agent, 0.2-0.6 part of thickening agent, 0.1-0.4 part of antifoaming agent and 5-30 parts of water. The preparation method of the leather dressing treatment composite material comprises the following steps of: weighing the raw materials in parts by weight; melting the graining paste with water, and uniformly stirring for a future use; slowly adding the ammonia water to the brightening agent under stirring, and adjusting the pH value of the brightening agent to 5.5-7.5; and adding the graining paste and auxiliaries for various purposes after adjusting the pH value of the brightening agent, and uniformly stirring to obtain the leather dressing treatment composite material. The leather dressing treatment composite material disclosed by the invention has extremely excellent heat resistance, not only can increase the attractive feeling of the leather surface, improve the durable performance of the leather surface, modify the leather surface defects and increase the using value of the leather surface, but also can increase the varieties of the leather surfaces, and therefore, the application range is extensive.

Description

technical field [0001] The invention relates to the field of leather chemical industry, in particular to a leather modification treatment composite material and a preparation method thereof. Background technique [0002] As a leather surface finishing material, leather finishing agent can significantly improve the performance of leather, expand the application range of leather and improve the grade of leather products. Acrylic resin leather finishing agents have a series of advantages, such as good film-forming properties, strong adhesion, simple production process and low cost, and are favored by the leather industry and have been developed rapidly. However, common acrylic resin emulsion coatings have the disadvantages of stickiness due to high temperature, poor aging resistance, no function of increasing the variety of patterns on the leather surface, narrow application range, etc., and their use is limited.
