Problems solved by technology

However, the current water-based paint products still have the following defects: 1. Most of them use water-based alkyd resin as the base material, which has poor adhesion and anti-corrosion performance cannot meet the needs; 2. There is still a certain gap in construction performance, which is not suitable for dip coating construction; 3. , Early water resistance is poor, not suitable for open-air construction

Abstract

The invention belongs to the technical field of paint and specifically relates to black waterborne automotive chassis paint and a preparation method thereof. The black waterborne automotive chassis paint is prepared from the following raw materials of 20 to 25% of self-emulsification acrylic modified epoxy ester resin, 20 to 25% of waterborne epoxy ester dispersoid, 0.5 to 1.0% of a waterborne drier, 0.01 to 0.5% of graphene, 1 to 2% of carbon black, 5 to 10% of compound zinc phosphate, 10 to 15% of barium sulfate, 1 to 2% of a corrosion inhibitor, 1 to 2% of an environment-friendly solvent, 0.1 to 0.2% of a neutralizing agent, 0.2 to 0.5% of a defoaming agent, 0.4 to 0.6% of a leveling agent, 0.3 to 0.5% of a base material wetting agent, 15 to 39.5% of deionized water and 0.5 to 1.0% of athickening agent. The black waterborne automotive chassis paint disclosed by the invention has very low smell; meanwhile, the product has the advantages of good dryness, good early water resistance and excellent salt spray resistance property.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a black water-based automobile chassis paint and a preparation method thereof. Background technique [0002] With the increasing awareness of environmental protection, countries around the world have successively formulated the limit standards and regulations for volatile organic compounds (VOC) emissions. Water-based paint has the characteristics of green, energy saving, safety and convenient function, and has been developed rapidly in all countries in the world. Water-based paint is a pure environmental protection product diluted with water. Compared with traditional solvent-based paints, it has the characteristics of no organic solvents such as formaldehyde, toluene, and xylene. It is a new generation of environmentally friendly products. Because of its energy saving and environmental protection, it will not cause harm or pollution to the human body and the envir...
