Problems solved by technology

[0002] At present, the adhesives are mainly oil-based solvents, but most of the organic solvents they contain are flammable, explosive, volatile, smelly, and pollute the environment and affect human health.
[0003] Although water-based adhesives are environmentally friendly adhesives, water-based adhesives use water as the basic medium, which has the disadvantages of long drying time, poor adhesion to non-polar surfaces, and poor water resistance.
[0004] Traditional adhesives are mostly prepared from petroleum resources and synthetic chemicals. However, with the depletion of petroleum resources and the enhancement of people's awareness of environmental protection, traditional adhesives are subject to certain restrictions.

Description

technical field [0001] The invention belongs to the field of polymer chemistry, and in particular relates to a two-component solvent-free vegetable oil-based adhesive. Background technique [0002] At present, the adhesives are mainly oil-based solvents, but because most of the organic solvents they contain are flammable, explosive, volatile, smelly, and pollute the environment and affect human health. [0003] Although water-based adhesives are environmentally friendly adhesives, water-based adhesives use water as the basic medium, which has the disadvantages of long drying time, poor adhesion to non-polar surfaces, and poor water resistance. [0004] Traditional adhesives are mostly prepared from petroleum resources and synthetic chemicals, but with the depletion of petroleum resources and the enhancement of people's awareness of environmental protection, traditional adhesives are subject to certain restrictions. Therefore, renewable resources and biomaterials have been p...
