preparation example Construction

[0060] The preparation method of described light-cured coating of the present invention, comprises the steps:

[0061] The polyurethane acrylic resin, the saturated polyester resin, the active monomer and the photosensitizer are thoroughly mixed uniformly in proportion, and if there are auxiliary agents, they are mixed uniformly together to obtain the photocurable coating.

[0062] In a preferred embodiment of the present invention, after feeding in proportion, stir at 60-150rpm / min for 0.5-2h, heat up to no more than 50°C, stir for 0.5-2h and then filter to obtain the photocurable coating. More preferably, stir separately for 1 h.

[0063] In a preferred embodiment of the present invention, the temperature is raised to 40-50°C.

[0064] In a preferred embodiment of the present invention, the filtering conditions include: the filtering pressure is 0.1-0.15 MPa. More preferably, the pore size of the filter is ≤1 μm, preferably 1 μm.

[0065] The polyurethane acrylic resin, t...

Abstract

The invention relates to the technical field of coatings, and especially relates to a photo-curing coating, and a preparation method and an application thereof. The photo-curing coating is mainly prepared from, by weight, 20-60 parts of polyurethane acrylic resin, 5-60 parts of saturated polyester resin, 10-50 parts of an active monomer, 1-20 parts of a photo-sensitizer, and 0-5 parts of an additive. The preparation method includes a step of mixing the raw materials uniformly according to ratio to prepare the photo-curing coating. The photo-curing coating is prepared from the polyurethane acrylic resin, the saturated polyester resin, the active monomer and the photo-sensitizer in specific use amount ratio, so that after curing, the coating has excellent anti-scratching effect, high-temperature resistance and anti-aging property, allows aluminum plating, and is excellent in sealing performance with an aluminum layer.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a light-curing coating and its preparation method and application. Background technique [0002] In recent years, with the development of science and technology, people have put forward higher and higher requirements for living standards, quality, air, ecology and other needs. Among them, materials such as home decoration, furniture, and membrane materials need to be non-toxic, harmless, non-volatile organic compounds (VOCs), and environmentally friendly. [0003] The traditional aluminized coating is a solvent-based system, with a high proportion of organic solvents and high VOCs content, which causes serious pollution to the production and use environment; in addition, because the coating contains solvents, more energy is required to make the coating film. This process Uses a lot of energy. In addition, when solvent-based aluminized coatings are produced by the molding proce...
