Summary of the invention
The purpose of this invention is to provide a kind of end, the general simple painted imitation metal fluorocarbon paint of finish paint, not only simplified working procedure, improved the construction tolerance, reduced whole construction cost, also solved shortcomings such as color and lustre lacking uniformity, fullness ratio difference.
The present invention is achieved in that a kind of simple painted imitation metal fluorocarbon paint and preparation method, formulation ratio:
Component A:
Fluorocarbon resin 65-75 part
Anti-settling agent 8-12 part
Vinyl acetate between to for plastic cellulose slurry 5-8 part
Defoamer 0.2-0.5 part
N-BUTYL ACETATE 2-8 part
Dimethylbenzene 2-10 part
Fluorine-carbon modified polyacrylic acid flow agent 0.1-0.5 part
Organically-modified siloxanes increases sliding flow agent 0.1-0.3 part
Metallic pigment slurry 7-10 part
Photostabilizer 0.1-0.5 part
UV light absorber UV-1 0.1-0.5 part
Described anti-settling agent is polyamide wax and dimethylbenzene to be stirred earlier in 4: 1 ratio make.
Described vinyl acetate between to for plastic cellulose slurry is that vinyl acetate between to for plastic Mierocrystalline cellulose and dimethylbenzene are evenly made in 4: 1 ratio dissolving.
Described metallic pigment slurry is that metallic pigment powder (as aluminium silver powder, gold copper powder) and N-BUTYL ACETATE are evenly made by dissolving earlier in 3: 1.
Processing sequence is to disperse the fluorocarbon resin input in the cylinder and add anti-settling agent, vinyl acetate between to for plastic cellulose slurry, defoamer stirred 5 minutes under 800 rev/mins rotating speed, drop into N-BUTYL ACETATE, dimethylbenzene, fluorine-carbon modified polyacrylic acid flow agent, organically-modified siloxanes then successively and increase sliding flow agent, metallic pigment slurry, photostabilizer, UV light absorber UV-1, press 1000-1200 rev/min rotating speed high speed dispersion 10-15 minute again, treat that the metallic pigment slurry is uniformly dispersed fully, detect qualified back discharging, promptly make component A finished product.
Described B component (solidifying agent) is to be the aliphatic isocyanates of base-material with six inferior vulcabond (HDI).
Described component C (thinner) is formed by N-BUTYL ACETATE, pimelinketone and the dimethylbenzene mixed by 2: 1: 1.
By set of dispense than A: B: C=1: 0.1: 0.3-0.5, the imitation metal fluorocarbon paint of making are painted on the good cement works exterior wall surface of sealing treatment, and following characteristics are compared with prior art arranged: 1. cost is low; 2. application is simple and easy, does not need the finish paint Lacquer finish; 3. color and gloss are even; 4. super weathering resistance of a specified duration; 5. You Yi chemical resistant properties; 6. outstanding stain resistance.
