Abstract

The present invention discloses one kind of green powdered paint and its preparation process. The green powdered paint consists of re-dispersible polymer latex powder 5-20 wt%, white cement 20-40 wt%, calcium carbonate 20-45 wt%, titanium white powder 5-25 wt%, diatomite 2-8 wt%, bentonite 1-2 wt%, cellulose ether 0.2-0.5 wt%, defoaming agent 0.2-0.5 wt% and coloring pigment 0-4 wt%. It is prepared through mixing all the components in a stirrer, and packing. It is used after mixing with water in construction site. It has the combined decoration functions of both putty and emulsion paint and may be used widely for decorating inner and outer wall.

Description

technical field [0001] The invention belongs to the field of dry powder coatings, in particular to an environment-friendly dry powder coating and a preparation method thereof. Background technique [0002] With the development of science and technology, people's understanding of environmental protection and sustainable development is getting deeper and deeper. In the coatings industry, it is the general trend to replace the heavily polluting solvent-based coatings with water-based coatings and powder coatings, and water-based coatings have been widely used. However, the architectural water-based latex coatings currently used are composed of polymer emulsions, pigments and fillers, various additives and water. Among them, additives and water are used for the production and storage of coatings, accounting for more than half of the weight and price of coatings. Most of the water-based architectural latex paint is water (about 60%), and the solid content is only 40%. The storag...
