Example Embodiment
[0019] Example 1
[0020] A method for preparing plastic plating parts. The modified polyester film is used for vacuum sputtering, and then a thermal adhesive layer is compounded on the modified polyester film, and then the modified polyester film is positively pressure-formed into the desired plastic The plated part has the same shape, and finally the finished product is injection molded. The hot-bonding layer is a material that can be hot-bonded with plastic castings during injection molding. The plastic casting is 4 circular rings connected in sequence.
[0021] The modified polyester film is prepared by melting saturated polyester and polyurethane, adding curing agent and auxiliary agent, and then coating and curing the carrier film, and then tearing off the carrier film.
[0022] Further, when melting, the mass ratio of the saturated polyester, polyurethane, solvent, curing agent and auxiliary agent is 80:20:50:5:5; when melting, the saturated polyester, polyurethane, curing ...

[0027] A method for preparing plastic plating parts. The modified polyester film is used for vacuum sputtering, and then a thermal adhesive layer is compounded on the modified polyester film, and then the modified polyester film is positively pressure-formed into the desired plastic The plated part has the same shape, and finally the finished product is injection molded. The hot-bonding layer is a material that can be hot-bonded with plastic castings during injection molding. The plastic casting is 4 circular rings connected in sequence.
[0028] The modified polyester film is prepared by dissolving saturated polyester and polyurethane, adding a curing agent and an anti-hydrolysis agent, and then coating and curing the carrier film and tearing off the carrier film.
[0029] Further, when melting, the mass ratio of the saturated polyester, polyurethane, solvent, curing agent and anti-hydrolysis agent is 60:5:45:3:3.
[0030] Wherein, the curing temperature is 25°C....

[0033] Example 3
[0034] A method for preparing plastic plating parts. After vacuum sputtering, a modified polyester film is used to print a hot-adhesive layer on the modified polyester film, and then the modified polyester film is positively pressure-formed into the desired plastic The plated part has the same shape, and finally the finished product is injection molded. The hot-bonding layer is a material that can be hot-bonded with plastic castings during injection molding. The plastic casting is 4 circular rings connected in sequence.
[0035] The modified polyester film is prepared by melting the saturated polyester and polyurethane, adding a curing agent and an anti-UV agent, and then coating and curing the carrier film and tearing off the carrier film.
[0036] Further, when melting, the mass ratio of the saturated polyester, polyurethane, curing agent and anti-UV agent is 95:40:8:8.
[0037] Wherein, the melting temperature is 230°C. The curing temperature is 80°C. The thi...
