Embodiment 1

[0021] Prepared from the following components by weight:

[0022]

[0023] Wherein the epoxy equivalent of the epoxy resin is 650g / EQ, and the carboxyl acrylic polyester is 50mg KOH / g.

Embodiment 2

[0025] Prepared from the following components by weight:

[0026]

[0027] Wherein the epoxy equivalent of the epoxy resin is 730g / EQ, and the carboxyl acrylic polyester is 60mg KOH / g.

[0028] Get the experimental result mean value after the experiment to embodiment 1-3:

[0029]

[0030]

[0031] The epoxy equivalent of epoxy resin is about 650-750g / EQ, and the cured polyester resin is carboxy acrylic polyester, and carboxy acrylic polyester is about 50-60mg KOH / g. Since carboxy acrylic polyester is a low-temperature curing polyester resin, According to the above material ratio, the curing temperature during production can be reduced from the traditional 190°C x 15min to 150°C x 20min, so it can reduce the energy consumption during painting production, increase the toughness of the aluminum wheel hub, and ensure the durability of the wheel hub. Impact resistance, carboxylated acrylic polyester reacts with epoxy to obtain a relatively high leveling effect; use hydro...

Abstract

The invention discloses low-energy-consumption powder coating for hub coating, and relates to the technical field of powder coating. The low-energy-consumption powder coating comprises epoxy resin, cured polyester resin, a leveling agent, benzoin, auxiliary agents and pigment, and is characterized in that the coating is prepared from, by weight, 200-430 parts of the epoxy resin, 180 to 230 parts of the cured polyester resin, 8-10 parts of the leveling accelerator, 2-3 parts of the benzoin, 10 to 15 parts of the wax powder, 20 to 40 parts of the auxiliary agents and 2 to 10 parts of the pigment; the epoxy equivalent of the epoxy resin is about 650 to 750 g / EQ; the cured polyester resin is carboxyl acrylic polyester the acid value of which is about 50 to 60 mg KOH / g; the leveling acceleratorand the benzoin are respectively an acrylate copolymer and benzoin; the wax powder comprises Clariant degassing wax powder and BYK degassing wax powder; the auxiliary agents comprise a flow auxiliaryagent, a curing agent, a precipitating agent, a polishing agent and barium sulfate; the pigment comprises titanium dioxide, carbon black, iron oxide yellow and zinc chrome yellow; and the coating hasthe characteristics of low fixed energy consumption, good leveling effect and stable adhesion.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a powder coating for coating low energy consumption wheel hubs. Background technique [0002] Automobile wheels are an important part of auto parts. With the growth of China's auto parts industry, the wheel industry has gradually grown. In recent years, the macroeconomic policy mainly to stimulate domestic demand has provided the foundation and guarantee for the steady development of the automobile industry. Judging from the trend of the automobile market, the impact of macroeconomic policies on the automobile market runs through the year. The rapid growth of GDP provides a broad demand space for the automobile industry, and the demand for automobile wheels will increase with the growth of automobile sales. In the next few years, China's automobile sales are expected to continue to grow steadily, providing opportunities for the development of the automobile wheel industr...
