Modified UV paint and preparation method thereof

Abstract

The invention relates to a modified UV paint and a preparation method thereof, and belongs to the field of coating. The modified UV paint comprises the following components in percentage by weight: 20-40% of an oligomer, 5-30% of thermoplastic polyurethane resin, 1-10% of a diluent monomer, 30-50% of a diluent, 0.1-5% of an additive and 0.5-5% of a light initiator. The invention further discloses a preparation method of UV paint and an application of the coating. The coating has good performance, is subjected to spray coating on the surface of an integral seamless product of metal and plastic or glass and plastic, is stripped off by an adhesive tape to achieve excellent decoration and performance protection of paint on the plastic position, is not left on glass or plastic and has a clear boundary with the metal and the plastic or with the glass and the plastic without generating a hand feeling.

Description

technical field [0001] The invention relates to a modified UV paint and a preparation method thereof, belonging to the field of paint. Background technique [0002] In the prior art, the integrated seamless appearance product of glass and plastic, metal and plastic has become a bright spot in the electronics industry and other industries, and is more and more widely used. However, in the integrated seamless appearance products of glass and plastic, or metal and plastic, since the surface of the plastic part does not have a dense and smooth appearance like glass or metal, it is often necessary to separately decorate the surface of the plastic deal with. In the prior art, the plastic surface is generally decorated by spraying UV paint. However, during the spraying process of UV paint, it is very easy to be sprayed on the glass or metal surface that does not need to be decorated at the seamless connection with the plastic, and because the UV paint is brittle, and some UV pain...
