Problems solved by technology

There are also obvious defects: firstly, it is more complicated in use and has many requirements, such as construction conditions and matching materials; secondly, the coating itself is rigid, insufficient in elasticity, and the surface material of the coated object is not suitable. , and affected by cracking, peeling, etc., the service life is not long; again, it pollutes the environment, and the organic volatiles of solvent-based coatings are extremely unfriendly to the environment

Abstract

Waterborne PVDF (polyvinylidene fluoride) fluorocarbon coating comprises waterborne PVDF fluorocarbon coating primer (I), waterborne PVDF fluorocarbon coating finish (II), waterborne PVDF fluorocarbon coating metallic glossy paint (III), and waterborne PVDF fluorocarbon coating varnish (IV), wherein one or any of the waterborne PVDF fluorocarbon coating primer (I), the waterborne PVDF fluorocarbon coating finish (II), the waterborne PVDF fluorocarbon coating metallic glossy paint (III) and the waterborne PVDF fluorocarbon coating varnish (IV) are applied in sequence and comprise, by weight 10-75% of PVDF fluorocarbon emulsion, 25-50% of acrylic emulsion, 5-15% of a film-forming aid, 10-30% of a pigment, 15-30% of a filler, 1-3% of an aid, 0.1-0.5% of an antibacterial mildew preventive, 0.5-3% of a thickener, and the balance of water.

Description

technical field [0001] The invention relates to a water-based PVDF polyvinylidene fluoride fluorocarbon coating and a coating method thereof, in particular to a coating coating suitable for outdoor application. Background technique [0002] Solvent-based coatings are currently the most common architectural coatings. In construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry, household goods and other fields, solvent-based coatings are still widely used as coatings. [0003] Traditional solvent-based coatings are mainly made from hydrocarbon solvents and oxygenated solvents. There are also obvious defects: firstly, it is more complicated in use and has many requirements, such as construction conditions and matching materials; secondly, the coating itself is rigid, insufficient in elasticity, and the surface material of the coated object is not suitable. , and affected by cracking, peeling, etc., the service life is not lon...
