Embodiment 1

[0108] Use the UV-curable treatment agent in Preparation Example 1, optionally use a solvent to adjust the viscosity to the Iwata cup for about 9 seconds, spray it on the PMMA plastic substrate with an air spray gun, and then pre-bake it in an oven at 60°C for 3 to 5 minutes , the thickness of the coating film is 1~3 microns, and then, through the medium pressure mercury lamp (400 mJ / cm 2 ) for UV exposure. Then, spray UV electroplating primer (manufactured by Changxing Chemical Industry Co., Ltd., ETERCURE8250U-9A), then pre-bake in an oven at 60°C for 5-10 minutes, and then pass through a medium-pressure mercury lamp (800 mJ / cm2). 2 ) for ultraviolet exposure, the thickness of the primer is 10-15 microns, and the substrate with the coating film is prepared.

Embodiment 2

[0110] The UV-curable treatment agent and the manufacturing method are the same as those in Example 1, except that the substrate is changed to a PS plastic substrate.

Abstract

The present invention provides an ultraviolet curable treatment agent, which comprises: (a) a monomer containing at least one double bond or an oligomer of at least one double bond or a mixture thereof; (b) a photoinitiator; and (c) a thermoplastic A resin wherein, based on 100 parts by weight of component (a), the content of component (b) is 0.5-20 parts by weight, and the content of component (c) is 30-1,000 parts by weight.

Description

technical field [0001] The invention relates to an ultraviolet (UV) curing substrate pretreatment agent, in particular to an ultraviolet curing treatment agent used in the coating industry. Background technique [0002] Coatings are used in a wide range of applications, from daily necessities to high-tech electronic products, such as furniture, auto parts, cosmetic casings, and casings of various 3C electronic or electrical products (such as digital cameras, notebook computers, and mobile phones, etc.) Coatings are applied to substrates to provide a protective or decorative finish. [0003] Commonly used substrates, such as wood, glass, metal or plastic substrates, will have grease, oxide scale, hydroxide, dust and other dirt attached to the surface of the substrate during manufacturing, processing, handling and storage. In order to ensure a good coating effect, the surface of the substrate must be clean (ie no oil, no rust) and free of defects (ie no scratches), otherwise ...
