Embodiment 1

[0027] The base powder of the moire type powder coating with flashing effect is made of the following raw materials in mass percentage:

[0028]

[0029] The above raw materials are mixed evenly, melted and extruded by an extruder, tableted, air-cooled, milled, and sieved to obtain a mosaic-patterned powder coating base powder with a glittering effect.

[0030] Add aluminum powder YM2065, according to 0.8% of the total mass of the primer, to the moire-type powder coating primer with flashing effect, bond at 60°C, and set the bonding time to 12 minutes, to obtain a moire-type powder coating with a shimmering effect powder coating.

[0031] The moire-patterned powder coating with sparkling effect prepared in this example was heated and cured in an electric blast drying oven, the curing temperature was 200° C., and the curing time was 12 minutes.

[0032] The performance test results of the obtained coating film after curing are shown in Table 1:

[0033] Table 1 Example 1 P...

Embodiment 2

[0036] The base powder of the moire type powder coating with flashing effect is made of the following raw materials in mass percentage:

[0037]

[0038]

[0039] According to the process described in Example 1, the moire type powder coating with glittering effect was prepared, the difference being that: the aluminum powder YM2065 was added according to 0.7% of the total mass of the primer, the bonding temperature was 62°C, and the bonding time was set to 10 minutes.

[0040] The curing temperature is 210° C., and the curing time is 10 minutes.

[0041] The performance test results of the obtained coating film after curing are shown in Table 2:

[0042] Table 2 embodiment 2 performance testing result

[0043]

Embodiment 3

[0045] The base powder of the moire type powder coating with flashing effect is made of the following raw materials in mass percentage:

[0046]

[0047]

[0048] According to the process described in Example 1, the moire type powder coating with glittering effect was prepared, the difference was that: aluminum powder YM2065 was added according to 0.6% of the total mass of the primer, the bonding temperature was 58°C, and the bonding time was set to 15 minutes.

[0049] The curing temperature is 220°C, and the curing time is 8 minutes.

[0050] The performance test results of the obtained coating film after curing are shown in Table 3:

Abstract

The invention belongs to the field of powder coating and particularly relates to a continuous pattern type powder coating with a flashing effect as well as a preparation method and application thereof. The powder coating is prepared by binding base powder and aluminum powder, wherein the base powder is prepared from the following raw materials in percentage by weight: 55.6 to 60.8 percent of polyester resin, 4 to 4.2 percent of glycoluril crosslinking agent, 0.18 to 0.22 percent of acid catalyst, 0.8 to 1 percent of leveling agent, 0.9 to 1.1 percent of benzoin, 0.2 to 0.4 percent of pattern assistant, 27.5 to 31.68 percent of filler and 5 to 6 percent of pigment. The preparation method of the continuous pattern type powder coating comprises the following steps of uniformly mixing raw materials, performing melt extrusion by an extruder, and performing tabletting, air cooling, grinding and sieving to obtain the base powder; binding the aluminum powder and the base powder to obtain the power coating; the prepared continuous pattern type powder coating with the flashing effect is cured to obtain a coating film product; according to the powder coating disclosed by the invention, the functions of covering power, color and metal flashing effect of a flash coating and an angle-dependent optical effect are achieved, effective combination of the aluminum powder and an art texture type powder coating with good decorative effect is realized, and a good development prospect is produced.

Description

technical field [0001] The invention belongs to the field of powder coatings, and in particular relates to a moire powder coating with a flashing effect, a preparation method and an application thereof. Background technique [0002] Artistic powder coatings make the surface of the coating film have beautiful and clear patterns, give the coated device a beautiful and colorful appearance, or make the defects on the surface of the coated object covered by its texture effect to improve the decorativeness of the coating film , to obtain decorative effects that are difficult to achieve with ordinary decorative powder coatings, so it has been greatly developed in recent years. [0003] Metallic flash paint is favored by the market for its unique "flash effect". With the improvement of people's living standards, people's aesthetic standards for cars are getting higher and higher. From high-end cars to low-end mini-cars, pickups, and even agricultural vehicles and motorcycles, metal...
