Abstract

The invention relates to a double-component adhesive for a card-making compound material and a preparation method. The double-component adhesive is characterized by comprising a component A and a component B, wherein the component A comprises 50-100 parts by weight of polyurethane gel solution; and the component B comprises the following materials in parts by weight: 5-30 parts of a curing agent and 0.01-0.1 part of an additive. The preparation method comprises the following steps: preparing the polyurethane gel solution, and then uniformly mixing the polyurethane gel solution with the curing agent and the additive and stirring for 30-90min at the speed of 500r / min, thereby acquiring the end product of the double-component adhesive. The double-component adhesive disclosed by the invention is used for coldly compounding a PET laser film aluminum surface with a PVC substrate, the operation is simple, the opening time is long, the peel strength is high, and the bonding combination property is excellent; and the laser surface of the compound material is smooth and is free from corrugation or wrinkle, and thus the prepared card can show perfect laser luster.

Description

technical field [0001] The invention belongs to the technical field of card making materials, in particular to a two-component adhesive for card making composite materials and a preparation method. Background technique [0002] Laser film generally uses computer dot matrix lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc., and transfers the holographic image with rainbow dynamics and three-dimensional effects to PET, BOPP, PVC or coated substrates through molding. Therefore, the laser film of various substrates can present a beautiful holographic laser brilliance under the irradiation of light. With the movement of the light source or the change of the observation point, changing laser color patterns will be produced, which are colorful and multi-eyed. Luxurious style. Composite the aluminum surface of the PET laser film with the PVC substrate, and print the ink on the PET surface of the composite profile, and the ca...
