Problems solved by technology

At present, the commonly used primer materials are generally composed of polyester with hydroxyl groups as the main agent and curing agent or amino resin with isocyanate groups. On the one hand, they are not resistant to high temperature, and on the other hand, the adhesion of ink on it is not enough. , it is necessary to apply anothe

Abstract

The invention discloses functional primer applicable to UV (ultraviolet) printing as well as a preparation method and a use method of the primer. The functional primer applicable to UV printing is prepared from raw materials in parts by weight as follows: 30-40 parts of polyurethane acrylate resin, 5-10 parts of polyester acrylic resin, 10-15 parts of oil-free alkyd resin, 5-10 parts of UV-curable resin, 1-2 parts of a siliane coupling agent, 2-5 parts of a dispersant, 1-1.5 parts of a leveling agent, 1-2 parts of a defoaming agent and 2-5 parts of inorganic nanoparticles. Polyurethane acrylate resin and polyester acrylic resin are selected and matched for use, so that the good softness of polyurethane acrylate resin can be played, and the defect of poor adhesion of polyurethane acrylate resin can be made up by means of polyester acrylic resin; the oil-free alkyd resin added to the primer increases the hardness and the high-temperature resistance of the primer; in the curing process of a coating, double curing including photocuring and thermocuring is selected, the curing degree and the physical strength of the primer are guaranteed while the early rapid curing is met, and the curing degree is high.

Description

technical field [0001] The invention relates to the technical field of primers, in particular to a functional primer suitable for UV printing, a preparation method and a use method thereof. Background technique [0002] At present, various forms of PET printing films and aluminized films are widely used in soft packaging, hard packaging, decorative materials and other fields. The applications in these areas require high adhesion between the ink layer or the aluminized layer and the PET film. Focus on. [0003] The methods of enhanced printing and aluminum plating include corona treatment and primer treatment, among which corona treatment is the most commonly used film surface treatment method, but it has disadvantages such as poor stability and large investment, and is suitable for continuous production processes; The treatment method has good stability, the surface tension of the treated PET film is not affected by time, and the cost is low, no special equipment and proces...
