Abstract

The invention relates to a method for preparing aqueous latex paint by using modified cellulose gum. The method comprises the following steps of: firstly, adding deionized water into a container, adding the modified cellulose gum with a mass percent of 0.3 to 0.6 into the deionized water with stirring to obtain a mixture, and uniformly stirring the mixture; secondly, adding a PH regulator, a dispersant, a deforming agent and a bactericide into the mixture and uniformly stirring the mixture; thirdly, adding kaolinite, talcpowder, titanium oxide and heavy calcium carbonate into the mixture in turn, adding ethylene glycol with stirring at a middle speed, and uniformly stirring the mixture; fourthly, performing high-speed dispersion for 40 to 60 minutes and grinding the products by using a sand mill; fifthly, slowly adding phenylethylene-acrylic emulsion and the deforming agent into the mixture and stirring the mixture; and finally, adding an leveling agent of acrylic polymers and the deionized water into the mixture. The aqueous latex paint prepared by the method not only guarantees product performance but also has low production cost.

Description

technical field [0001] The invention relates to a water-based latex paint, in particular to a preparation method of the water-based latex paint. Background technique [0002] Generally, thickeners for latex paints are divided into two categories: organic thickeners and inorganic thickeners. Among them, there are three types of organic thickeners: natural polymers, cellulose derivatives and synthetic polymers. Among them, the main representative products of cellulose derivatives are hydroxyethyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose derivatives and sodium carboxymethyl cellulose. This kind of thickener has better thickening effect. [0003] Currently on the market, cellulose derivative thickeners mainly use hydroxyethyl cellulose and sodium carboxymethyl cellulose, of which hydroxyethyl cellulose accounts for about 55-50%, and sodium carboxymethyl cellulose accounts for about 35%. -40%. Large-scale foreign and private coating companies mainly use hyd...
