Embodiment 1

[0032] Embodiment 1 Vacuum coating and metallization decoration process of 42-inch TV frame

[0033] (I) Plastic cleaning process, remove the surface protection film from the 42-inch TV frame made of ABS material. Use a lint-free cloth dipped in absolute ethanol to wipe it once along the edge of the frame in one direction, and then another person wipes it once with a dry lint-free cloth (wipe the same area in the same way). Wipe around the entire surface frame in this way, and then check to see if there are any foreign objects such as residual fibers and dust on the surface of the surface frame. After the confirmation is completed, the plastic molding cleaning process is completed.

[0034] (II) Primer spraying process, the 42-inch TV panel frame molded parts that have been cleaned and installed on the positioning tool are transported to the primer spraying room at a speed of 3.5m / min through the conveyor chain, and sent to Shenzhen Weihengji Paint Factory The provided primer...

Abstract

The invention discloses an environment-friendly plastic metalizing decoration process and belongs to the field of plastic decoration. The method comprises the following steps: a, cleaning a molded plastic part; b, coating primer, wherein the plastic part is coated with acrylate UV (ultraviolet) primer and then cured so that the uneven surface of a base material is flattened with the primer; c, coating a film in vacuum, wherein the plastic part is put into a vacuum film coating cavity of vacuum film coating equipment, the vacuum degree of the vacuum film coating cavity is controlled to be between 10<-2> and 10<-3>Pa, and performing vacuum continuous film coating after plasma dust collection; d, coating protective paint, wherein the plastic part is coated with the acrylate UV protective paint which is matched with the UV primer and then cured to form a paint film with a certain hardness; and e, pasting a film on the plastic part, and packaging the plastic part. The environment-friendly plastic metalizing decoration process produces less waste gas and waste water, is more environment-friendly than a conventional metalizing process; and the product has light weight, the appearance design of the product is free, and the individual requirement of consumers can be met.

Description

technical field [0001] The invention belongs to the field of decoration of plastic parts, and in particular relates to a vacuum continuous metallization coating decoration process. Background technique [0002] In 2011, Samsung Electronics made a sensation in the industry with its D7000, 8000, and 9000 series products with an ultra-narrow metal frame of about 0.5cm, so that the ultra-narrow frame has become the benchmark of the industry, and metallization has also become a decorative effect. The trend is spreading. In fact, in IT There is another masterpiece in the world: the Iphone4 frame is made of aluminum alloy and pure metal, which also changes the appearance design and decoration feeling of the mobile phone. The metallization effect is getting stronger and stronger, so home appliances and portable electronic products are undergoing changes in metallization effect decoration. [0003] At the 2012 CES exhibition, Samsung Electronics released its annual strategic concept...
