Abstract

The invention relates to solvent-free type fiber reinforced epoxy paint and a preparation method of the solvent-free type fiber reinforced epoxy paint. The solvent-free type fiber reinforced epoxy paint comprises an ingredient A and an ingredient B, wherein the ingredient A mainly comprises the following ingredients in parts by weight: 20 to 50 parts of liquid epoxy resin, 5 to 20 parts of reactive diluents, 10 to 40 parts of titanium pigment, 10 to 40 parts of toughening agents, 10 to 30 parts of fillings and 4 to 10 parts of adhesion promoters, the ingredient B comprises the following ingredients in parts by weight: 20 to 60 parts of cashew modified amine, 20 to 60 parts of ketimine, 0.5 to 1.5 parts of adhesion promoters and 5 to 20 parts of active diluents, and the weight ratio of the ingredient A to the ingredient B is (4.5-5.5):1. The solvent-free type fiber reinforced epoxy paint is economic and environmental-friendly, the toughness is high, and wider industrial application prospects are realized.

Description

technical field [0001] The invention relates to the field of coating, in particular to a solvent-free fiber-reinforced epoxy coating and a preparation method thereof. Background technique [0002] In recent years, the requirements for environmental protection have become increasingly urgent and strict, so many countries have successively issued laws and regulations on the control of volatile organic compounds (VOC). The paint industry has therefore developed towards non-volatile aspects. Among them, water-based coatings are more and more popular because of their characteristics of no solvent volatilization, economical and environmental protection. However, the existing water-based coatings are not ideal in terms of crack resistance and impact resistance. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a solvent-free fiber-reinforced epoxy coating, which includes A component and B component, [0004] The A compone...
