Problems solved by technology

[0002] Traditional baby wheel hubs are generally made of monochrome polypropylene, ABS engineering plastics, and metal aluminum alloy. Among these three types of wheels, metal aluminum alloy wheels are the most beautiful, but their high cost is not conducive to companies quickly occupying the market with price advantages. Although monochromatic polypropylene and ABS engineering plastics are relatively low in cost, they are monotonous in color and rough in appearance

Embodiment Construction

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] The invention relates to a vacuum coating process for a baby wheel hub, which mainly includes a plastic hub, and is characterized in that: the vacuum coating step is as follows

[0016] Ⅰ. The surface of the plastic hub is sprayed with a color primer, and the thickness of the spray is 0.01mm-0.03 mm;

[0017] Ⅱ. Baking the plastic wheel once, the baking temperature is 70-85 degrees, and the baking time is 2 hours-3 hours;

[0018] Ⅲ. Spray the color topcoat for the second time on the plastic wheel hub after baking, and the thickness of the spraying is 0.01mm-0.02 mm;

[0019] Ⅳ. Carry out secondary baking on the plastic hub, the baking temperature is 75-85 degrees, and the baking time is 2 hours-3 hours;

[0020] Ⅴ. Carry out vacuum coating on the baked plastic hub;

[0021] Ⅵ. Spray protective paint on the vacuum-coated plastic hub, the thickness of which is 0...

Abstract

The invention discloses a vacuum coating process for a hub of a baby carriage. The process is characterized by comprising the following steps of: I, spraying colored base paint on the surface of a plastic hub, wherein the spraying thickness is 0.01 to 0.03mm; II, performing primary baking on the plastic hub at the temperature of between 70 and 85 DEG C; III, performing secondary spraying on the baked plastic hub by using colored finish paint, wherein the spraying thickness is 0.01 to 0.02mm; IV, performing secondary baking on the plastic hub at the temperature of between 75 and 85 DEG C; V, performing vacuum coating on the baked plastic hub; and VI, spraying protective paint on the plastic hub subjected to vacuum coating, wherein the spraying thickness is 0.005 to 0.01mm. The plastic hub subjected to vacuum coating has the advantages of metal light color, bright color and low cost compared with that of a metal hub, has abundant colors and can be matched with baby carriage frames in different colors.

Description

technical field [0001] The invention relates to the technical field of processing technology for plastic parts of baby carriages, in particular to a vacuum coating process for the hub of baby carriages, and in particular to the technological process thereof. Background technique [0002] Traditional baby wheel hubs are generally made of monochrome polypropylene, ABS engineering plastics, and metal aluminum alloy. Among these three types of wheels, metal aluminum alloy wheels are the most beautiful, but their high cost is not conducive to companies quickly occupying the market with price advantages. Although monochromatic polypropylene and ABS engineering plastics are relatively low in cost, they are monotonous in color and rough in appearance. [0003] Based on the above reasons, it is still necessary to further improve the existing child wheel hub processing technology so that it has both low cost and high quality characteristics. Contents of the invention [0004] The o...
