Problems solved by technology

Although the acrylic commercial-grade reflective film sold on the market has stronger ink absorption performance than the PET commercial-grade reflective film, it is easy to be exposed due to the use of acrylic as the surface layer, and the operability is poor.

Embodiment Construction

[0013] A method for preparing a printable and unbreakable reflective film, comprising the following process steps:

[0014] a. Apply the adhesive, use PET as the carrier film, apply a layer of 5-10 μm adhesive evenly on the PET by scraping, bake in an oven at 80°C for 2 minutes, and put it on when it is not completely dry. its removal;

[0015] b. Bead planting: plant glass beads with a diameter of 42-50 μm on the plastic surface of PET through fluidized air pressure, and press the beads into the adhesive through a rubber pressure roller with 4Kg air pressure;

[0016] c. Coating a spacer layer, using PET with microbeads as a carrier, coating the acrylic emulsion on the microbeads as a spacer layer by scraping the surface of the microbeads, and the spacer layer is evenly coated on the surface of the microbeads;

[0017] d. Coating the reflective layer, put the semi-finished product with the spacer layer into the vacuum aluminum coating machine to coat the reflective layer, an...

Abstract

The invention relates to a method for producing anti-light film, in particular to the film that can be printed and not easy to tear down when uncover it, provided with following steps: a, coating some binder on PET; b. positioning beads; c. coating wall; d. plating reflecting layer; e. coating protective layer; f. coating blotting layer; g. composing it with ionic paper to get anti-light film products. Comparing to the commercial class anti-light film of PET, the film that can be printed and not easy to tear down when uncover it by the method of the invention provides with better printing and jetting properties, broader selectivity of ink; while comparing to that of PET type business class reflecting film, it is not easy to tear down when uncover it, so it can be operated with simplicity.

Description

technical field [0001] The invention relates to a preparation method of a reflective film, in particular to a preparation method of a printable and difficult-to-break reflective film. Background technique [0002] The ink-absorbing performance of PET used on the surface of PET-type commercial-grade reflective film currently on the market is poor, and the ink printed on the surface is difficult to penetrate into the inner layer of PET. Therefore, in order to enhance the durability of printed products, many companies only choose PET special ink produced by Jujo, Japan. The price of this ink is very high. Currently, the red ink sold in the market is RMB 520 / kg, which greatly increases the printing cost. Although the acrylic commercial-grade reflective film sold on the market has stronger ink absorption performance than the PET commercial-grade reflective film, it is easy to be exposed due to the use of acrylic as the surface layer, and the operability is poor.
