The invention relates to weather-resisting type single-
coating powder paint with
metal pattern effect. The weather-resisting type single-
coating powder paint comprises bottom
powder A and
metal powder B; the bottom powder A is prepared from the following components in percentage by weight: 55 percent to 80 percent of weather-resisting type
polyester resin, 4.0 percent to 6.2 percent of a curing agent, 0 to 40 percent of modified
barium sulfate, 0.3 percent to 1.5 percent of a
plasticizer, 0.02 percent to 2 percent of a curing accelerator, 1 percent to 5 percent of an auxiliary agent, 0 to 25 percent of
pigment and 0.05 percent to 0.5 percent of a texturizing agent; the weather-resisting type
polyester resin is synthesized from the following raw materials:
neopentyl glycol, butylene glycol, 2-methyl-1,3-
propylene glycol,
cyclohexanedimethanol, 2-butyl-2-ethyl-
propylene glycol,
terephthalic acid and the like. By adopting modified
polyester, the weather-resisting type single-
coating powder paint with
metal pattern effect has excellent
weather resistance and also has a three-dimensional pattern effect; the weather-resisting type single-coating powder paint with metal pattern effect can be thickly applied and a thickly coated film with the thickness of 60UM to 120UM is formed by coating in one step; the coated film only needs to be cured for one time; the weather-resisting type single-coating powder paint with metal pattern effect has the characteristics of 10-year
weather resistance, high metal stereoscopic impression, clear pattern effect, good coverage, good
mechanical property, low cost, no
pollution to the environment and the like.
