Description
Technical field
The present invention relates to a kind of paint structure and manufacture method thereof, be meant especially a kind ofly can on a substrate, form a paint structure and a manufacture method thereof that has characteristics such as glossiness, fineness and wear resistance be good concurrently.
Background technology
Consult Fig. 1, a kind of existing paint structure 1 is formed on the substrate 9.This paint structure 1 comprises: a structural sheet 11 and is formed on the tie coat 12 of a upper surface of this structural sheet 11.
This structural sheet 11 and tie coat 12 are to have being of a greater particle size pulverous metal or coating of the prepared one-tenth of resin of a metal oxide (can be silver powder 111 or aluminium powder with color) and a predetermined amount, utilize a conventional spray paint method (Spraying Technology) to be formed on this substrate 9 and make.
Silver powder 111 usage quantitys of the existing paint structure 1 of this kind need the utmost point to be lower than the usage quantity of this resin (Resin), just can so that prepared and this paint structure 1 present a glossiness.But because that this silver powder 111 accounts for the total amount of this coating is very low, so this silver powder 111 presents in this resin and disperses and can't concentrate, so that color can't reach the requirement of fineness.The RAC of this paint structure 1 (R.C.A., Abrasion Wear Tester herein; R.C.A company wearability test machine) value is about 120, and glossiness (Gloss) is approximately less than 40.
Consult Fig. 2, another kind of existing paint structure 2 is formed on the substrate 7.This paint structure 2 comprises: a structural sheet 21 and is formed on the tie coat 22 of a upper surface of this structural sheet 21.
This structural sheet 21 and tie coat 22 are to have than being of a small particle size pulverous metal or coating of the prepared one-tenth of resin of a metal oxide (can be silver powder 211 or aluminium powder with color) and a predetermined amount, utilize a conventional spray paint method to be formed on this substrate 7 and make.
Though the existing paint structure 2 of this kind has higher fineness, can't meet the demand of glossiness, and has influence on the wear resistance of this paint structure 2.The RAC value of this paint structure 2 is about 120 herein, and glossiness is approximately less than 40.
Another existing paint structure, be to utilize the secondary spraying method to form bilayer structure (double layersstructure), the first upper surface that the silver powder of a predetermined amount is sprayed on a substrate is to form lower floor's structural sheet, and a upper surface that again UV glue is sprayed on this understructure layer is to form a upper strata tie coat.Though this kind UV coating can improve the glossiness on this paint structure surface, but need to increase spraying and UV sclerosis steps such as (Curing), cause the increase of man-hour and fabrication steps.
Consult Fig. 3, another kind of again existing paint structure 3 is formed on the substrate 6.This paint structure 3 comprises: a structural sheet 31 and is formed on the tie coat 32 of a upper surface of this structural sheet 31.
This structural sheet 31 and tie coat 32 are a coating that will mix the prepared one-tenth of resin of a plurality of big particle diameter silver powder 311, a plurality of small particle size silver powder 312 and a predetermined amount, utilize a conventional spray paint method to be formed on this substrate 6 and make.Though the existing paint structure 3 of this kind has higher fineness, can't reach the requirement of wear resistance.
Above mentioned various existing paint structure can't have characteristics such as glossiness, fineness and wear resistance be good simultaneously concurrently, therefore, how preparing the paint structure that has above-mentioned several characteristics simultaneously, is the relevant required a great problem that overcomes of dealer of current research exploitation coating and paint structure.
Summary of the invention
