Embodiment 1

[0030] For spraying the appearance effect of high imitation ceramics, the materials to be sprayed are first pre-treated: the materials are polished and then T-treated; the processed materials are baked at 80 ℃ for 1 hour.

[0031] The treated materials are given a ceramic primer, and two ceramic primers are applied, including the first ceramic primer and the second ceramic primer; the ceramic coating is based on crude oil: curing agent: thinner The weight ratio is 100: 16: 40 The proportioning preparation; Wherein, described curing agent model is H-1350; Described diluent model is 0-843; Configured primer adopts 300 order filter; Adopt the spraying air pressure of 3~4 kg at the end, 10 cm Spraying distance, spraying in the environment of temperature and humidity 25 / 75 ℃ / RH; after the first ceramic primer and the second ceramic primer, both need to be cured at 70 ℃ for 20 minutes, and finally The dry film thickness is 16 μm. After the ceramic primer process was completed, the ...

Embodiment 2

[0039] For spraying the appearance effect of high imitation ceramics, the materials to be sprayed are first pre-treated: the materials are polished and then T-treated; the processed materials are baked at 80 ℃ for 1 hour.

[0040] The treated materials are given a ceramic primer, and two ceramic primers are applied, including the first ceramic primer and the second ceramic primer; the ceramic coating is based on crude oil: curing agent: thinner The weight ratio is 100: 16: 60 The proportioning preparation; Wherein, described curing agent model is H-1350; Described diluent model is 0-843; Configured primer adopts 300 mesh filter; Adopt the spraying air pressure of 4 kg, the spraying distance of 20 cm , spraying in an environment with a temperature and humidity of 25 / 75 ℃ / RH; after the first ceramic primer and the second ceramic primer, both need to be cured at 85 ℃ for 35 minutes, and the final dry film The thickness is 20 μm. After the ceramic primer process was completed, the ...

Abstract

The invention belongs to the field of spraying, and specifically relates to a high imitation ceramic appearance effect spraying method. The high imitation ceramic appearance effect spraying method comprises the steps of (1) pretreatment, namely, grinding and polishing a material and then carrying out T treatment; (2) ceramic primer spraying, namely, spraying a ceramic primer for the first time, and then spraying the ceramic primer for the second time; (3) intermediate paint spraying, namely, spraying color paint; (4) UV primer spraying; (5) NCVM (Non-conductive vacuum metallization); (6) UV intermediate paint spraying; and (7) UV finishing paint spraying. Products sprayed by adopting the process have the advantages of high surface hardness, strong scratch resistance, strong collision resistance, simple production process, low cost and the like.

Description

technical field [0001] The invention belongs to the field of spraying, and relates to a spraying process, in particular to a spraying method with a high imitation ceramic appearance effect. Background technique [0002] With the official application of the 5G network, if the 4G metal middle frame structure is used, the antenna signal will be shielded, and a long section of plastic must be used to solve the signal problem in the world. In this way, the use of anode technology cannot solve the problem of appearance color, and currently only spraying can be used process to achieve. [0003] At present, the metal spraying surface treatment process of electronic consumer products in the market is generally: material T treatment + baking at 80°C for 1 hour + Primer (treatment agent 1) + primer 1 (treatment agent 2) + primer 2 (Surface 1) + Primer 3 (Surface 2) + sanding + ultrasonic cleaning + baking at 80°C for 1 hour + primer 4 (Surface 3) + sanding + ultrasonic cleaning + baki...
