Abstract

The invention belongs to the field of polyurethane coating materials and particularly relates to a phenol-formaldehyde resin modified polyurethane / polyurea coating material and a preparation method therefor. The phenol-formaldehyde resin modified polyurethane / polyurea coating material comprises a component A and a component R, wherein the component A comprises phenol-formaldehyde resin, halogenated polyether polyol and isocyanate, and the component R comprises polyether polyol A, amino-terminated polyether B and an amine chain extender; and the halogenated polyether polyol is chloro-polyetherpolyol or bromo-polyether polyol and has the functionality of 2.5 to 3.5, the relative molecular mass of 500 to 2,000 and the halogen content of 8wt% to 30wt%. According to the phenol-formaldehyde resin modified polyurethane / polyurea coating material prepared by the method, the acid / base resistance, heat resistance and flame retardance of the coating material are greatly enhanced, the phenol-formaldehyde resin modified polyurethane / polyurea coating material can be applied to the field of production under high-temperature strong-acid strong-base conditions, and the range of application of polyurethane / polyurea coating materials is extended. The invention further provides the preparation method for the phenol-formaldehyde resin modified polyurethane / polyurea coating material.

Description

technical field [0001] The invention belongs to the field of polyurethane coatings, in particular to a phenolic resin modified polyurethane / polyurea coating and a preparation method thereof. Background technique [0002] With the gradual improvement of people's requirements for the environment, health and sustainable development, the development of environmentally friendly coatings is the general trend. Polyurethane / polyurea is a new type of solvent-free and high-performance coating developed and developed to meet the needs of environmental protection after powder coatings, light-curing coatings and water-based coatings. At present, the polyurethane / polyurea hybrid system used in China has been applied in building waterproofing, concrete in the electric power or metallurgical industry, coating protection for the inner and outer walls of steel structure facilities with high temperature resistance and anti-corrosion requirements, steel chemical equipment and concrete tanks in ...
