Abstract

The present invention belongs to the technical field of polymer materials, and particularly relates to a hybrid curing peelable coating material, wherein the raw materials comprise, by weight, 45-100 parts of an epoxy resin, 45-100 parts of a UV-curable resin, 0.05-0.1 part of a UV leveling agent, 1-3 parts of a UV dispersing agent, 0.2-1 part of a defoamer, 3-6 parts of a photoinitiator A, 3-6 parts of a photoinitiator B, and 10-20 parts of fumed silica. The preparation method comprises: adding partial UV dispersing agent and partial defoamer to a high-speed disperser, dispersing for 15-20 min at a rotation speed of 600-800 r / min, adding fumed silica, dispersing for 30-50 min at a rotation speed of 1600-2800 r / min, reducing the rotation speed to 300 r / min, adding an epoxy resin, a UV-curable resin, the remaining defoamer, the remaining UV dispersing agent, a UV leveling agent, a photoinitiator A and a photoinitiator B, uniformly stirring, continuously dispersing for 5-10 min, uniformly mixing, filtering, and removing the filter residue to obtain the product. According to the present invention, the hybrid curing peelable coating material of the present invention has a short drying time, the cured product has good rust resistance and the like, and the preparation method has characteristics of simple process and easy control.

Description

[technical field] [0001] The invention belongs to the technical field of polymer materials, in particular to a hybrid cured peelable coating and a preparation method thereof. [Background technique] [0002] Peelable paint is a temporary protective material with polymer as the main film-forming substance. It is sprayed on the surface of the object when it is used, and it will protect the object for a short time after the film is formed; The film layer is gently peeled off from the surface of the object to be coated by hand, which will not only cause no damage to the surface of the object to be coated, but also make the appearance of the original device as clean as new. Strippable coatings are widely welcomed by industries such as instruments, meters, home appliances, machinery, automobiles, and electronic appliances due to their convenient coating and easy peeling, and are developing rapidly. [0003] There are three types of current strippable coatings: 1. Solvent-based str...
