Abstract

The invention discloses an epoxy resin adhesive. The adhesive comprises, by weight, 60-80 parts of epoxy resin, 2-6 parts of dicyandiamide, 5-10 parts of a plasticizer, 0.2-2 parts of a curing accelerator, 1-5 parts of an antioxidant, 1-5 parts of an anti-ultraviolet agent and 10-20 parts of a solvent. A preparation method of the adhesive comprises the following steps: adding raw materials into a mixing hopper according to a certain ratio, starting a variable speed stirrer, and continuously stirring under a rotating speed of 400-500r/min for 1-2h; and filtering, and removing residual bubbles. An application of the adhesive in advertisement consumables is characterized in that the adhesive bonds all layers of the consumables through primary curing and hot-pressing secondary curing, and finally forms a protection layer through cross-linking curing of an image layer. The epoxy resin adhesive has good curing performance, mechanical strength, impact strength and ageing resistance, and can be applied in the advertisement consumables to prolong the service life of the advertisement consumables and reduce the production cost of the advertisement consumables.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an epoxy resin adhesive and its preparation method and application. Background technique [0002] Epoxy resin adhesive is a liquid or solid adhesive composed of epoxy resin, curing agent, accelerator, modifier, diluent, filler, etc. The bonding process of epoxy resin adhesives is a complex physical and chemical process, including steps such as infiltration, adhesion, and curing, and finally generates a cured product with a three-dimensional cross-linked structure to combine the adherend into a whole. [0003] There are some reports on epoxy resin adhesives in the prior art. For example, the invention patent with the patent number 201110267847.2 discloses a high-efficiency epoxy resin adhesive and its preparation method and application. The high-efficiency epoxy resin adhesive includes the following components by weight: 60-100 parts of epoxy resin, 15-60 parts of curing agent, 10-40 pa...
