Abstract

The invention relates to an anti-glare hardened film for in-mold decoration, in the technical scheme, an anti-glare hard coating is coated on a substrate film; the components for preparing the anti-glare hard coating and the weight parts thereof are as follows: 10 to 30 parts of polyurethane acrylate prepolymer, 15 to 40 parts of grafted modified acrylic monomer, 5 to 15 parts of anti-glare particles, 0.5 to 7 parts of photoinitiator, 0.05 to 2 parts of flatting agent, and 30 to 70 parts of solvent. The anti-glare hardened film for in-mold decoration has high transparency and high haze, can effectively prevent the surface reflection from achieving the anti-glare purpose while ensure high clarity of an IMD product pattern, simultaneously has above 2H hardness and excellent anti-corrosion performance, can meet the performance requirements on most 2D and 3D product forming and processing, does not crack when the stretching and forming height reaches above 6mm, and can be widely applied in the fields of anti-glare treatment requirements and matt panel decoration.

Description

technical field [0001] The invention belongs to the technical field of in-mold decoration (IMD), in particular to an anti-glare cured film for in-mold decoration. Background technique [0002] In-mold decoration (IMD) refers to the process of forming a decorative pattern on the surface of the product when the product is injection molded in the mold. Generally, a film with a decorative pattern is formed in advance, and then the film with a decorative pattern is formed. Thermoforming to form a predetermined shape, the film is cut and then placed in the cavity of the injection molding mold, preferably molten material is injected into the cavity, the film is combined with the molten material to form a product with a decorative pattern. The appearance of products made by in-mold decoration has a stronger sense of reality than products that are patterned by painting after injection molding, and the pattern does not have any adverse phenomena such as fading or falling off. It is wi...
