Aluminum button and preparation method thereof

[0073] The present invention also provides a method for preparing the aluminum texture button described in the above technical solution, comprising the following steps:

[0074] a) mixing unsaturated polyester resin, FX-218 flexible resin liquid, methyl ethyl ketone and cobalt salt, after reaching the gelation time, adding a viscosity modifier to adjust the viscosity to obtain a blank;

[0075] b) making the blank into a blank to obtain a button blank;

[0076] c) Spraying a top coat on the button blank to obtain a button.

[0077] Among them, the unsaturated polyester resin, FX-218 flexible resin liquid, methyl ethyl ketone, cobalt salt, viscosity regulator, and the type and amount of topcoat are all consistent with those described in the above technical solution, and will not be repeated here. The operations in steps a) to c) are consistent with those described in the above technical solution, and will not be repeated here.

[0078] Among them, before the topcoat is spraye...

[0082] 1.1 Preparation of billet

[0083] New billet raw material:

[0084] Material A:

[0085] Ortho-phthalic unsaturated polyester resin 988N-1 94%;

[0086] FX-218 flexible resin liquid 6%;

[0087] Material B:

[0088] Methyl ethyl ketone 0.9%;

[0089] Cobalt naphthenate 0.9%;

[0090] Styrene 1.0%.

[0091] New blank preparation:

[0092] Add FX-218 flexible resin liquid to the o-phthalic unsaturated polyester resin, then add the same amount of cobalt salt and methyl ethyl ketone, test the gelation and adjust the gelation time to meet the production requirements, and then add styrene to adjust the viscosity to form a new Blank slurry; made into button blanks according to common button production standards.
