Abstract

The invention discloses nanometer calcium carbonate paint and a production process. The nanometer calcium carbonate paint consists of soft water, wetting agents, dispersing agents, anti-corrosion agents, anti-freezing agents, PH value regulating agents, film forming agents, defoaming agents, nanometer calcium carbonate, fine triple superphosphate, triple superphosphate, talc powder, kaolin, cellulose, emulsion, flatting agents and thickening agents. The production process of the nanometer calcium carbonate paint comprises the following steps of: (1) prefabricating nanometer calcium carbonate pulp; (2) preparing water solution of auxiliary agents; (3) taking and using the prefabricated nanometer calcium carbonate pulp according to the solid content and preparing pulp; (4) pumping ground pulp into a thinning tank by a pump; and (5) putting the cellulose into the step (4) to obtain finished products. The nanometer calcium carbonate paint and the production process have the beneficial effects that: 1, the performance of the paint is improved; 2, the shielding effect is improved; 3, the protection capability is enhanced; 4, the anti-bacterium and deodorization effects are enhanced; and5, the product cost is reduced.

Description

technical field [0001] The invention relates to a coating and a production process, in particular to a nanometer calcium carbonate coating and a production process. Background technique [0002] With the rise of nanotechnology in recent years, the application of nano-calcium carbonate in coatings in order to improve the performance of coatings is one of the hot topics in the coatings industry. Now only a few countries in the world, such as the United Kingdom and Japan, use a large amount of nano-calcium carbonate in coatings, and the technical control is quite strict. There is no domestic manufacturer that uses nano-calcium carbonate as the main raw material to produce coatings, and the application of nano-calcium carbonate in coatings is still in the laboratory research stage. [0003] In the 21st century, the production of nano-calcium carbonate in my country has made great progress. In particular, the establishment of many 10,000-ton nano-calcium carbonate production li...
