The preparation technique is simple; and the prepared acrylic-resin-modified water-based nitrocellulose emulsion for paint has the advantages of high stability, high flexibility, high adhesive force, certain fullness, yellowing resistance, water resistance and no pollution.

The invention relates to a production method of breathable leather. The condition that in a production method of the breathable leather, environment pollution in the production process is free and the problem of product breathability is available can be solved at present can not be splved. The production method comprises the following steps: (1) preparing a sizing agent, wherein the sizing agent consists of polyurethane resin and color chips in a weight ratio of 100:1.2, and the viscosity of the sizing agent is adjusted to be 1500cps; (2) mounting release paper onto a PU (Polyurethane) production line, firstly, drying the release paper at 100 DEG C, subsequently coating the release paper with the sizing, and furthermore, drying at 140 DEG C so as to obtain a half-finished product; (3) printing a dry method surface layer of the release paper with patterns and glossiness by using a three-edition printing machine; (4) compounding the release paper with a piece of base cloth by using a binding agent; and (5) washing in water by using a graining machine; and (6) inspecting to be qualified to obtain a breathable leather product. By adopting the production method, the product breathability can be solved.

The invention provides waterborne tall oil alkyd resin emulsion and a preparation method thereof. Waterborne alkyd resin is prepared by taking tall oil extracted from papermaking waste liquid as a raw material; a preparation process comprises: (1) taking the tall oil to react with diethanolamine to prepare tall oil diethanolamide; (2) preparing a polyester intermediate by taking the tall oil diethanolamide and dibasic acid with a sulfonic group to react with dihydric alcohol; (3) taking the polyester intermediate, vegetable oil, fatty acid, polyatomic alcohol and polybasic acid to react and adding de-ionized water and dispersing to prepare alkyd resin water dispersoid. The tall oil extracted from the papermaking waste liquid is effectively utilized, and an application range of the tall oil is also expanded.
