A high-quality water-based fluorosilicon metal paint production process

Abstract

The invention discloses a high-quality waterborne fluorosilicone metal paint production process which comprises the following steps: preparing a slurry main material: namely sequentially inputting the raw materials of the slurry main material into a liquid suction groove, sucking the raw materials of the slurry main material to a slurry tank by virtue of a vacuum pipe, and starting a high speed disperser for dispersing; adding slurry auxiliary materials: namely inputting the slurry auxiliary materials into a powder suction groove and sucking the slurry auxiliary materials to the slurry tank by virtue of a vacuum pipe; adding the slurry into a low speed tank; adding paint mixing main materials: namely adding the paint mixing main materials to the grinded slurry; adjusting the viscosity; adding paint mixing auxiliary materials: namely adding the paint mixing auxiliary materials into ingredients, wherein the paint mixing auxiliary materials comprise the raw materials: 5-9 parts of a fluorocarbon flatting agent, 8-12 parts of a fluorocarbon water repellent agent and 30-35 parts of water; defoaming for 5-20 minutes in vacuum; filtering by virtue of a bag type filter; and filling. According to the process disclosed by the invention, the quality of the paint produced is good, the change on color along with time is less, the surface hardness is high, and the paint is hard to fall. The process is relatively simple in process, the production efficiency can be improved and the production cost is low.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of paint production technology, in particular to the technical field of high-quality water-based fluorosilicon metal paint production technology. [0003] 【Background technique】 [0004] With the rapid development of China's economy, China's paint demand is increasing, and the quality requirements are getting higher and higher. Fluorosilicone water-based coatings are made of silicon-containing polymer aqueous dispersions and fluoropolymer aqueous dispersions. Membrane coatings. Coatings that use silicon-containing polymer aqueous dispersions and fluoropolymer aqueous dispersions as film-formers are called silicon-containing aqueous dispersion coatings and fluorine-containing aqueous dispersion coatings, collectively referred to as fluorosilicon water-based coatings. The fluorine-carbon bond in the polymer has a small bond length and a large bond energy. The F-C bond formed by it and the carbon atom ...

Problems solved by technology

Due to the superior performance of fluorosilicone coatings, they are more suitable for use in exterior wall coatings, especially latex paints for exterior walls. The existing fluorosilicone water-based coatings are more complicated to manufacture, and their performance cannot better meet people's needs.
