Abstract

The invention discloses a preparation method for carboxymethyl cellulose nitrate resin water-borne dispersoid and aims to solve the problems that a conventional nitrocellulose paint organic solvent is especially large in pollution and harm on environment and human health because of too high dosage of benzene solvents, so that stable emulsion can be obtained without additionally adding water-borne polymer resin. Carboxymethyl cellulose nitrate, resin, cellosolve, deionized water, an emulsifier and a plasticizer react at a proper temperature according to a proper sequence to prepare the carboxymethyl cellulose nitrate resin water-borne dispersoid. The preparation method is simple in process; the emulsion is uniformly dispersed; the prepared product is good in storage stability and good in film-forming property; water substitutes part of an organic solvent, so that the preparation method is environmentally friendly, very high in industrial production capacity and very wide in application prospect.

Description

technical field [0001] The invention relates to a method for preparing a water-based nitrocellulose resin material in the coating field, in particular to a method for preparing an aqueous dispersion of carboxymethylcellulose nitrate resin. Background technique [0002] With the development of society, especially recently, environmental pollution has attracted people's attention, and the requirements for the coating industry are getting higher and higher, especially the application of coatings is required to cause less environmental pollution. The solvent content in traditional solvent-based paints is often above 60%, the solvent content of nitro paint can be as high as 80% during construction, and the solvent content of solvent-based metallic paints for automotive coatings is as high as 85%. [0003] These volatile organic solvents (VOC) enter the atmosphere and cause environmental pollution. In addition, the paint used for home decoration will also produce VOC, which will ...
