Problems solved by technology

[0003] The current epoxy high-build primer is found in use. After the epoxy high-build primer is coated, its surface-drying and hard-drying time is relatively long, which makes the paint film of the epoxy high-build primer difficult to dry quickly and cannot meet the requirements. Use requirements in different situations

Abstract

The invention discloses a quick-drying epoxy high-build primer and a preparation process thereof, and belongs to the technical field of epoxy high-build primer. The quick-drying epoxy high-build primer comprises a component A and a component B. The component A comprises the following raw materials in parts by mass: 24-32 parts of epoxy resin; 8-12 parts of modified resin; 3-7 parts of an anticorrosive pigment; 2-5 parts of a coloring pigment; 3-7 parts of rutile titanium dioxide; 5-9 parts of a drier; 5-7 parts of a silane coupling agent; 2-7 parts of an anti-settling agent; 4-6 parts of a wetting dispersant; 3-7 parts of a reactive diluent; and 14-18 parts of a solvent. According to the quick-drying epoxy high-build primer and the preparation process thereof, the adhesive force, impact resistance and acid / alkali / salt resistance of the quick-drying epoxy high-build primer are better than those of the prior art, the film forming speed is high and smooth, the surface drying time and the hard drying time are shorter than those of the prior art, the quick-drying epoxy high-build primer can be quickly dried, the use requirements under different conditions can be met, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of epoxy high-build primers, in particular to a fast-drying epoxy high-build primer and a preparation process thereof. Background technique [0002] Epoxy high-build primer is composed of epoxy resin, modified resin, anti-corrosion pigment, color pigment, auxiliary agent, solvent and curing agent. It has the following characteristics: 1. Excellent adhesion and durability, abrasion resistance and impact resistance of epoxy high-build primer; 2. Excellent salt water resistance, oil resistance, alkali resistance and a certain degree of acid resistance 3. High solid content, can be used as thick film coating; 4. Outstanding anti-corrosion performance, it is the most ideal heavy-duty anti-rust coating for indoor. [0003] When the current epoxy high-build primer is used, it is found that after the epoxy high-build primer is applied, the surface-drying and hard-drying time of the epoxy high-build primer is long, ...
