Abstract
The invention provides a high-resistance film plating primer paint which comprises the following components in parts by weight: 5-40 parts of ten-functional polyurethane acrylic resin; 5-25 parts of difunctional aromatic polyurethane acrylic resin; 1-5 parts of an initiator; solvent A,15-25; solvent B,20-40; 0.05 to 0.2 percent of flatting agent. The primer coating of the present invention has excellent resistance, such as alcohol resistance. The invention also provides a method for preparing the high-resistance coating primer paint.
Description
Technical Field
The invention relates to the field of Ultraviolet (UV) curing coatings, in particular to a UV curing PVD coating, and more particularly relates to a high-resistance coating primer coating.
Background
Plastic products are widely used in many fields, such as lamp parts, automobile decorative parts, cosmetic cases, toys, daily small goods, and the like. In order to improve the surface decoration of plastic products and to show metallic effect, a vacuum coating (PVD) method is generally adopted to generate a layer of metal film on the surface of a plastic substrate. However, the vacuum-plated metal film is provided with a primer (primer) and a top-coat (finish), which respectively provide different properties, and are positioned on two sides of the metal film layer to improve physical and chemical properties such as adhesion, resistance (such as alcohol resistance, hand perspiration resistance and the like) and wear resistance of the plating film. Therefore, the paint plays an important role in the application of vacuum coating technology, and the performance of the paint can influence the use of plastic products.
Among many plastic products, cosmetic packaging materials (such as bottle bodies and bottle caps) are special applications, and contain contents such as perfume, skin care emulsion, cosmetic water and the like, while cosmetics such as perfume and the like contain components such as alcohol and the like, and the components have great influence on a coating layer on the surface of the packaging materials, so that the adhesive force of the coating is easily reduced, and the coating is easily dropped. Therefore, the paint for cosmetic packaging materials is required to have high resistance to components such as alcohol.
In addition, although the coating film paint includes a primer paint and a top coat paint, among the resistances, the resistance of the coating film primer paint is responsible for the coating layer falling. Because of the microscopic void space between the primer and the substrate, components such as alcohol can enter the void space, if the primer is not sufficiently resistant to alcohol, the primer can be directly peeled off from the surface of the substrate, and the whole coating structure with the coating film can be peeled off from the surface of the substrate, so that the appearance and the use of the cosmetic packaging material are affected.
In short, the primer coating of the PVD coating is required to have good resistance and meet the adhesion requirement.
[ Prior art 1] NC 101280154A provides an ultraviolet curing vacuum coating paint, which improves the adhesion performance to low surface tension substrates. However, the ethanol resistance obtainable according to this technique is greater than 1 hour, and the demand for cosmetic packaging materials is far from being met.
The prior art also has a solution to make primers with "alkyd + monomer", however, such a system primer has poor alcohol and perfume resistance.
Disclosure of Invention
In order to solve the defects in the prior art, the invention aims to provide a coating primer coating with high resistance, which comprises the following components in parts by weight:
in the high resistance coating primer coating according to the present invention, we propose to use a ten-functional urethane acrylic resin and a two-functional aromatic urethane acrylic resin. Among them, the cross-linking speed of the ten-functional polyurethane acrylic resin is fast, and a high cross-linking degree can be obtained after curing, providing excellent resistance. However, the high hardness associated with high functionality can result in poor adhesion between the coating and the substrate. The invention provides that the two-functional aromatic polyurethane acrylic resin is added into the coating, which can provide adhesion to both a substrate and a coating, and simultaneously, the benzene ring structure in the structure can provide adhesion and improve the resistance of the coating.
Note that in the high-resistance coating primer coating of the present invention, only the above two materials are resins which undergo radiation crosslinking curing. The adhesion of the primer layer of the prior art vacuum coating paint mentioned in the background section is provided by acrylate monomers, and the acrylic acid monomers have a small molecular weight and low crosslinking degree, so that the resistance of the whole coating is greatly influenced. In contrast, the present invention uniquely proposes the use of a difunctional aromatic polyurethane acrylic resin having a specific structure to provide adhesion while allowing for resistance.
In the high-resistance coating primer coating material of the present invention, preferably, it comprises, in parts by weight:
in the high-resistance coating primer coating of the present invention, preferably, the ten-functional urethane acrylic resin is a ten-functional aliphatic urethane acrylic resin.
In the high-resistance coating primer coating material of the present invention, the solvent A is preferably butyl acetate. The solvent B is preferably ethyl acetate. However, the choice of solvent may also be other solvents known to those skilled in the art.
A method for preparing the high-resistance coating primer paint comprises the steps of uniformly mixing a leveling agent and an initiator by using a mixed solvent of a solvent A and a solvent B, sequentially adding a ten-functional polyurethane acrylic resin and a two-functional aromatic polyurethane acrylic resin, and stirring for 30-45min by using a dispersing machine until uniformly mixed.
The high-resistance coating paint has the following technical effects:
1. the coating has excellent alcohol resistance, and the coating has very high resistance (alcohol resistance, salt water resistance, hand perspiration resistance, G1 liquid resistance, emulsion resistance and the like) after being cured by adding the ten-functional polyurethane acrylic resin and the two-functional aromatic polyurethane acrylic resin, and meanwhile, the adhesive force of the coating is very good.
2. The processing process is simple and convenient, and the operability is good.
