Summary of the invention
What the present invention will solve is the above-mentioned defective that existing umbrella cover coating processes exists, and a kind of follow-on umbrella cover coating and coating method are provided, and is intended to improve the quality and the aesthetic measure of umbrella cover.
The technical scheme that addresses the above problem employing is: imaginary powder type umbrella face fabric coating, it is characterized in that each component prepares by following weight ratio, and being made into each component sum of back is 100%:
Illusion-colour powder 20-25% PA glue 55-60% linking agent 1-3%
Antisticking agent 0.5-1.5% solvent 14-20%
The present invention also will provide a kind of coating method of imaginary powder type umbrella face fabric, it is characterized in that carrying out according to the following steps:
With illusion-colour powder 20-25% with dissolution with solvents after, add PA glue 55-60%, stir; Add linking agent 1-3% more successively, antisticking agent 0.5-1.5% and solvent, and the overall control that makes solvent stirs at 14-20%, forms standby glue X1;
Repeat above-mentioned steps and prepare standby glue X2;
The grey cloth that coats PA glue is placed on the board, regulates scraper to suitably highly, coating adhesive X1 is coated on the grey cloth again, controlled temperature applies upper fabric with coating adhesive X2 after the oven dry between 120-130 ℃, and controlled temperature is at 135-145 ℃;
Above-mentioned each component is by weight preparation, and being made into each component sum of back is 100%.
The described speed of a motor vehicle is controlled at 40-55m/min.
The preferred 21-23% of described illusion-colour powder, most preferably 22%; The preferred 57-59% of described PA glue, most preferably 58%; The preferred 1.5-2.5% of described linking agent, most preferably 2%; The preferred 0.8-1.2% of described antisticking agent, most preferably 1%; The preferred 16-18% of described solvent, most preferably 17%.The preferred plain goods of described lining.
Adopt imaginary powder type umbrella face fabric coating of the present invention and coating method thereof, the umbrella cover after the processing is bright in luster beautiful, novel fashion, and preventing ultraviolet effect is good.
Embodiment
Embodiment one, wash the flat coating of spinning the class umbrella cloth
Illusion-colour pulvis 22% (weight ratio, down together) with after the toluene dissolving, is added PA glue (polyacrylic ester) 58%, stir; Add vulcabond 2% more successively, clorafin 1% and toluene solvant, and the overall control that makes solvent is 17%.Stir, form standby glue X1; Repeat above-mentioned steps and prepare standby glue X2.
The grey cloth that coats PA glue is placed on the board, regulates scraper, again coating adhesive X1 is coated on the grey cloth to suitably highly, controlled temperature is between 120-130 ℃, after the oven dry coating adhesive X2 is applied upper fabric, controlled temperature is at 135-145 ℃, and the speed of a motor vehicle is controlled at 45-55m/min.
Coated lining is detected according to standard GB/T18830 through reaching the preventing coating protection tester with the HB902 antiultraviolet, and measured result is: average UPF UPFav=500, the transmitance of ultraviolet (UV) Aav wave band is 1.01%.And the corresponding industry standard QB/T1099-2005 of en-toutcas China National Light Industrial Products Department regulation, average UPF UPFav>30, transmitance<5% of ultraviolet (UV) Aav wave band.This shows that the umbrella cover that adopts coating method of the present invention to make, its antiultraviolet see through index and be higher than standard value far away.
The concrete data that detect are referring to Fig. 1.
Embodiment two
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 25%, PA glue 55%, vulcabond 3%, clorafin 1.2%, solvent 15.8%.
Embodiment three
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 20%, PA glue 60%, vulcabond 1%, clorafin 0.5%, solvent 18.5%.
Embodiment four
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 21%, PA glue 59%, vulcabond 1%, clorafin 0.5%, solvent 18.5%.
Embodiment five
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 23%, PA glue 57%, vulcabond 1%, methyl-silicone oil 0.5%, solvent 18.5%.
Embodiment six
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 20%, PA glue 60%, vulcabond 1%, clorafin 0.5%, solvent 18.5%.
Embodiment seven
Repeat embodiment one, and each component is prepared by following weight ratio:

Methyl-silicone oil 1.0% solvent 16%.
Embodiment eight
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 20%, PA glue 59%, vulcabond 1.5%, clorafin 1.5%, solvent 18%.
Embodiment nine
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 24%, PA glue 60%, vulcabond 1%, clorafin 1%, solvent 14%.
Embodiment ten
Repeat embodiment one, and each component is prepared by following weight ratio:
Illusion-colour powder 20%, PA glue 58%, vulcabond 1%, clorafin 1%, solvent 20%.
The coating of embodiment 11, percussion dry goods umbrella cloth
Repeat art technology, after the dissolving of illusion-colour pulvis 22% usefulness toluene, add PA glue (polyacrylic ester) 58%, stir, add vulcabond 2%, methyl-silicone oil 1% and toluene solvant more successively, and the overall control that makes solvent is 17%, stir, it is standby to form finished product glue X1; It is standby to repeat above-mentioned steps preparation finished product glue X2.
The grey cloth that coats PA glue is placed on the board, regulated scraper, again coating adhesive X1 is coated on the grey cloth to suitably highly.Controlled temperature is coated on coating adhesive X2 on this grey cloth after the oven dry at 120-130 ℃.Controlled temperature is controlled at 40-50m/min the 135-145 ℃ of speed of a motor vehicle.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
