Problems solved by technology

In addition, the physical properties of the paste and the chemical properties that require further curing at high temperatures make it unusable in some fields, such as the composite of honeycomb panels at room temperature.
[0005] In addition to high-end and expensive epoxy adhesives imported from abroad, it is difficult to see good toughness, high bonding strength, excellent durability and weather resistance in the domestic market, and can be relatively affordable, suitable for civilian processing of honeycomb composite panels in my country. Epoxy adhesives required for production

Abstract

The invention discloses a modified epoxy adhesive and a preparing method thereof. The adhesive is used for adhesive composite between an aluminum plate and an aluminum / paper honeycomb core or between a steel plate and the aluminum / paper honeycomb core, and the adhesive is composed of bi-component of component A and component B, wherein the ratio of the component A to the component B is 2 : 1 or 1 : 1, the component A is a modified epoxide resin system used as a base stock, and the component B is an amine curing agent system with modified amine and polyamide being principal materials and is used as a curing agent. The adhesive is prepared by preparing the component A and the component B respectively. The modified epoxy adhesive and the preparing method thereof have the advantages of being excellent in performance, simple in technology and low in cost.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a modified epoxy adhesive and a preparation method thereof. Background technique [0002] Honeycomb panel is a multi-layer composite panel composed of metal panel, aluminum / paper honeycomb core, metal bottom plate, and polymer adhesive. It has many advantages such as light weight, high strength, high rigidity, sound insulation, and thermal insulation performance. . It has been used in various civilian fields in foreign countries in the 1960s, and it has developed rapidly. In my country, cellular technology has only been used in various fields of civilian industry in recent years. It was previously limited to military fields. Aluminum honeycomb panel curtain wall has been widely used in the decoration of high-rise building exterior walls due to its light weight, high strength, high rigidity and many other advantages. The total thickness is 15mm, and the aluminum honeycomb pane...
