Abstract

The two-component primer includes component A and component B mixed in the weight ratio of 3-8. The component A includes epoxy resin liquid 25-40 (in weight portions, the same below), amino resin 1-5, stuffing 30-40; and the component B includes polyamide resin 35-50, xylene 28-36, cyclohexanone 20-28 and drier 1-5. The paint product of the present invention has great adhesion force, good toughness, good antifouling performance, high wear resistance, smoke resistance, gasoline resistance, acid and alkali resistance, high electric insulating performance, shock resistance, heat resistance, cold resistance and good fireproof performance. It is used as primer widely in different fields.

Description

technical field [0001] The present invention relates to a two-component paint product and its production and use, especially a paint product based on epoxy resin for primers. Background technique [0002] Paint refers to a type of film-forming substance that can dry and form a film when applied to the surface of an object, making the object beautiful and protected, or forming a film with other special functions on the surface of the object. Paint is a multi-component system, generally a viscous liquid. Since the function of paint is to protect different surfaces and environments, it needs to have mechanical strength, aging resistance, and corrosion resistance. [0003] The film-forming substances of paints mostly use high-molecular compounds, which are generally called resins for coatings. They should have the following properties: good solubility, good miscibility, good film-forming properties and wettability to pigments, and can impart certain properties to the coating fil...
