Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly plastic adhesive and a preparation method thereof. Background technique [0002] With the development of the national economy and the improvement of people's living standards, people put forward higher requirements for plastic products, not only to have excellent comprehensive properties, but also to have good bonding effects. The realization of the bonding effect is inseparable from the use of adhesives. Plastic adhesive is a polymer material with cohesive force, which is solidified by chemical reaction or physical interaction between the material itself and the interface, and can connect or bond the same or different material interfaces to achieve the bonding effect. [0003] At present, there are many types of plastic adhesives on the market, such as epoxy resins, cyanoacrylates, phenolic resins, and urea-formaldehyde resins. However, there are ...
