Manufacture method of light-cured composite film

Abstract

The invention discloses a manufacture method of a light-cured composite resin film, comprising the following steps of: (1) providing a plastic substrate, light-cured composite resin, a printing ink layer and plastic, wherein the plastic substrate is provided with an upper surface and a lower surface; (2) coating the upper surface of the plastic substrate with the light-cured composite resin; (3) impressing and solidifying the light-cured composite resin to form a plurality of patterns; (4) forming the plastic substrate and the plurality of patterns; (5) coating the printing ink layer on the lower surface of the plastic substrate; and (6) ejecting and attaching the plastic on the printing ink layer.

Description

technical field [0001] The invention relates to a film production method of photocurable composite resin, in particular to a film production method of photocurable composite resin which is firstly hardened and then formed. Background technique [0002] The traditional methods of improving the surface properties and added value of plastic products are nothing more than attaching metal film layers or artificial leather to plastic substrates, or using spraying or painting methods as surface coating layers. However, the lamination of the metal film layer or artificial leather needs to consider the adhesion ability of the above-mentioned adhesive layer and the plastic substrate, and its adhesiveness directly affects the durability of the product. The color variability and selectivity are relatively monotonous, and it is impossible to produce colorful and complex lines or 3D special effect graphics. If you want to improve the special texture of the surface after the above laminat...

Problems solved by technology

However, the disadvantage of the Dual cure process is that it must go through two hardening procedures, which will consume more time and fixed costs; and the surface of the plastic film has poor scratch resistance and wear resistance before the surface coating is cured by ultraviolet rays. It is easy to cause poor appearance due to damage to the film surface caused by process equipment and manual operation, and the production yield is greatly reduced; on the other hand, the final hardening step is after the final product molding step, that is, the downstream application end (such as the shell manufacturer) must After molding the shape of the shell, the step of resin hardening is carried out, so downstream customers must have UV curing equipment, which will increase the cost of downstream manufacturers, and will eventually lead to an increase in the process cost of the shell molding factory

[0004] Another example is that a research and development team moved the hardening step to before the molding step, but they still use non-extensible resin and apply the resin in a discontinuous manner, but This method also results in a complicated process, and at the same time, the discontinuous resin film also makes the surface protection function poor.
