Problems solved by technology

[0006] At present, the free radical photoinitiator system used in photocurable coatings has the disadvantages of oxygen inhibition, large curing shrinkage rate, and slow curing rate of cationic photoinitiator systems; the traditional solvent-free epoxy coating system has slow curing speed and poor wear resistance. Poor; In addition, the traditional FRP preparation process is complicated and cannot be formed at one time

Abstract

The invention relates to a preparation method of a photo-curable graphene solvent-free epoxy fiberglass reinforced plastic paint, in particular to a photo-curable graphene solvent-free epoxy fiberglass reinforced plastic paint and a preparation method thereof. The photo-curable graphene solvent-free epoxy fiberglass reinforced plastic paint is made from, by percent, resin, a monomer (an active diluent), glass powder, a photoinitiator A, a photoinitiator B, a defoaming agent, an adhesion promoter, and graphene oxide. During curing, the graphene oxide is reduced into graphene, so that improved adhesion, wear resistance and the like are imparted to a coating; the photo-curable graphene solvent-free epoxy fiberglass reinforced plastic paint also has the advantages of high curing speed, excellent corrosion resistance, good mechanical properties, good construction operability and the like. The photo-curable graphene solvent-free epoxy fiberglass reinforced plastic paint is applicable to pipeline joint patch, station buried pipelines, pipeline crossing external protection, pipeline elbows of different diameters and the like.

Description

technical field [0001] The invention relates to a light-cured graphene-type solvent-free epoxy glass steel coating, in particular to a light-curable graphene-type solvent-free epoxy glass steel coating and a preparation method thereof. technical background [0002] With the development of economy and science and technology, people's awareness of environmental protection is getting stronger and stronger, and they begin to pay attention to the use of environmentally friendly coatings. Green environmental protection coatings mainly include the following types: powder coatings, water-based coatings, solvent-free coatings, high-solid coatings and radiation curing. paint etc. Among them, light-curing coatings are environmentally friendly and energy-saving coatings developed in the 1960s that can undergo physical and chemical changes in a short period of time after being irradiated by light. Compared with, it has the advantages of fast curing speed, energy saving, no pollution, no...
