Abstract
A high-weatherability colour acrylate paint for plastics, especially for PVC plastics is prepared from fluorine acrylate resin or silicon acrylate resin (5-40 portions), volatile organic solvent (10-40), pigment over class-4 in sun-resistance (2-35) and assistant (0.1-20) through grinding, adding said solvent (10-50 portions) and filtering. Its advantages include excellent physical and chemical properties, high adhesion, sun-resistance and weatherability, not decolouring and powdering, refractory nature, and low cost.
Description
The present invention relates to technical field of coatings.
Paint for plastics on the market is large in the variety at present, and for example Anyang sun health care company limited produces, and main component is acrylic resin, ethenoid resin, lead powder and pigment; Hongshi Paint Co., Beijing produces, and main component is methyl methacrylate, mineral dye, pigment dyestuff, solvent, ethyl propenoate; The S2-12 plastics tailor-(made) coating that Handan Paint Factory produces.These coating are mainly used in electrical equipment, furniture, vessel class, are not suitable for outdoor use coating, and are easy to change because of it, and weathering resistance, resistance to deterioration, adhesion strength etc. are all undesirable.Through the domestic relevant document of national science and technology intelligence department retrieval, patent, investigate the domestic up till now coating products that still is not used in plastic door-window.Present domestic plastic door-window coloring mode has two kinds, and the one, adopt to paste color film mode, this pad pasting can only import, and price height and color variety are few, and easily curl in the position, corner, rake angle, can't overcome on the technology; The 2nd, adopt bicolor co-extrusion to go out, this method sticking power height, but owing to limited by extrusion equipment, color variety is few, can only single face painted, when door and window is pieced together after the welded corner joint clear angle, easily expose inner white type body, its technology is also complicated.Plastic door-window is the building doors and windows renewal product, and it is imperative to solve its coating decorations problem.
The purpose of this invention is to provide a kind of high-weatherability colour acrylate paint for plastics and preparation method thereof, its light permanency, good weatherability, not easy to change, the adhesion strength height, high thermal resistance is good, applied widely, be particularly suitable for doing frosting coating, particularly PVC plastics under the outdoor long-term exposure environment.Its technology is simple and easy to do, reliable, cost is low, can guarantee quality product.
The present invention is achieved in that a kind of high-weatherability colour acrylate paint for plastics, and its set of dispense ratio is: vinylformic acid fluoro-resin or acrylic silicon resin 5-40 part, sun-proof rank pigment 2-35 part more than 4 grades, volatile organic solvent 20-90 part.
Volatile organic solvent is best for fourth fat or fourth fat add toluene, and weight proportion is 2-3: 1.
Solvent burden ratio the best is 40-70 part.
Pigment ratio the best is 5-20 part.
Vinylformic acid fluoro-resin or acrylic silicon resin the best are 10-25 part.
Can add auxiliary agent 0.1-20 part, auxiliary agent can be dispersion agent, anti-settling agent, defoamer, flow agent, anti-scratch agent, wherein one or more.Can require allotment according to concrete working conditions.
Dispersion agent can be organic dispersing agent, as silicone or carboxylic-acid etc.
Anti-settling agent can be inorganic salts, as SiO2 or bentonite etc.
Preparation method of the present invention is: a kind of preparation method of vinylformic acid weather resistant plastics colo(u)r coating, it is characterized in that vinylformic acid fluoro-resin or acrylate silicone resin 5-40 part, it is pre-dispersed to add low volatile organic solvent 10-40 part, add sun-proof rank pigment 2-35 part more than 4 grades again, add auxiliary agent 0.1-20 part, carry out emulsification, grind, add above-mentioned solvent 10-50 part dilution at last again, filter, get product.
Vinylformic acid fluoro-resin or acrylic silicon resin the best are 10-25 part, and solvent the best is 40-70 part, and solvent is best for fourth fat or fourth fat add toluene, and the two weight proportion is 2-3: 1, and auxiliary agent is 1-15 part.
The present invention has good physical and chemical performance, and its outstanding advantage is: 1, light permanency, good weatherability; 2, not easy to change, be difficult for efflorescence; 3, high thermal resistance is good; 4, adhesion strength height; 5, applied widely, especially be fit to make the outdoor use plastic paint, be applicable to multiple plastics, especially the PVC plastics.Easy, the easy row of its technology, reliable, cost is low, can guarantee quality product.
Below in conjunction with embodiment the present invention is described further, but not as a limitation of the invention.
The set of dispense that below is several embodiment is than particular sheet:
Using method: spraying, also can brush etc.
Illustrate: aforesaid propylene acid fluoro-resin and acrylic silicon resin material, to use to protect and mould that printing ink company produces, the market is on sale.Pthalocyanine blue adopts domestic and international kind all can.
Its blending process is with above-mentioned.
Embodiment test-results performance index are as follows:
1, You Yi anti-weather performance
This coating can stand Exposure to Sunlight for a long time, drenches with rain, wind, severe cold and UV-light long-term irradiation.Prove that through national experiment of building material center detected result this coating can guarantee to use under outdoor environment, can not occur variable color, crackle in 10 years, come off, catabiosis such as efflorescence, decomposition occur.
2, with hard PVC plastics adhere firmly degree height
This paint spay-coating with several microns PVC surface uniform dissolution, makes acrylic molecules side chain and PVC molecule twine mutually in dissolving layer in the extremely short time behind PVC section bar surface, forms firm mutually mixed combination.Adhesion strength can reach 100% on PVC.
3, high and low temperature resistance excellence
This coating is thermoplastic coating, under 250 ℃, or-10 ℃, variable color can not occur and become fragile decomposing phenomenon.
4, fine corrosion resistance
Chemical such as acid, alkali, salt, grease, washing composition there is excellent resistivity.
5, time of drying is short, hardness is high, anti-pollution, good decorating effect.
6, color spraying is flexible and changeable, and is easy to use.
The key technical indexes of the present invention and Britain's like product contrast see the following form:
| Performance index | Standard index | Measured data | Britain company product index |
| Point to power (cross-hatching) surface drying drying time and did solid work pencil hardness acid and alkali-resistance (168h) washability (10000 times) shock-resistant weatherabilities (250h) heat resistance (250 ℃ * 30 minutes | 9 5%≤0.5h≤4h 〉=H is non-foaming, nothing comes off no wrinkling non-foaming, not having the no wrinkling nothing that comes off comes off, do not have wrinkling non-foaming, flawless efflorescence≤1 grade, nondiscoloration grade is not trickled in variable color≤2 | 100% 0.1h 3h 2H is qualified qualified non-foaming, and 1 grade of 0 grade of variable color of flawless efflorescence is qualified | 100% 0.5h 3h H is qualified, and qualified non-foaming flawless is qualified |
As seen, performance compares than Britain like product, the hardness height, and time of drying is short, good weatherability, and cost reduces greatly.
