Description

Water-based axle low-VOC special coating
Technical Field
The invention belongs to the field of coatings, and particularly relates to a water-based axle low-VOC special coating.
Background
The low VOC water-based alkyd steel structure coating is produced by adopting a general production process and production equipment, and when the paint paste is ground and dispersed, a large amount of heat is generated due to mutual continuous and high-speed operation of materials, grinding media, a grinding disc and the like. 1. Affecting the stability of the coating (thickening, precipitation, coagulation, coarseness return, jelly, etc.); 2. the production efficiency is low; 3. causing volatilization of organic solvents in the coating (harmful exhaust emissions).
With the increasing strictness of environmental protection policies, the VOC of aqueous coatings is also decreasing continuously. Since the automotive base paints require excellent decorative effects, they can be applied only at a low solid content, which results in the greatest emission of VOCs within the application of each coating. In the traditional solvent-based automobile base paint, 80% of VOC in the paint can be discharged into the atmosphere, and serious environmental pollution such as photochemical smog and the like is caused. Therefore, strict laws and regulations are set by developed countries in the western world to restrict VOC emissions during painting. China also provides relevant environmental protection laws and regulations to limit solvent-based automobile base color paint and push water-based automobile base color paint to the utmost.
CN107163828A discloses an ultralow-VOC (volatile organic compound) high-adhesion water-based automobile base paint which is prepared from the following raw materials in percentage by weight: 50-70% of acrylic polyurethane dispersion; 0.5-2% of acetyl tributyl citrate; 1-5% of alkali swelling thickener; 18-31.5% of deionized water; 6-10% of full-solid aluminum pigment; 0.5% of wetting agent; 0.1% of defoaming agent; 2-2.5% of water-based wax; 0.4 percent of organic base.
The above patents are greatly different from the components of the present invention, and do not affect the novelty and creativity of the present invention.
Disclosure of Invention
The invention provides an ultra-low VOC aqueous automobile base paint and a preparation method thereof, aiming at solving the technical problem of overlarge VOC (volatile organic compound) release amount of the existing automobile base paint. The paint has the characteristics of relatively bright metallic appearance and good adhesive force to automotive interior and exterior plastic.
In order to achieve the purpose, the invention is realized according to the following steps:
the water-based paint special for the axle low VOC is characterized in that: the components and parts by weight are as follows:
Figure BDA0002871916310000011
Figure BDA0002871916310000021
moreover, the thickener composition is:
WG-2299 thickener 2-5
WG-2350 thickener 1-3.
Further, the dispersant is composed of:
WF-7630B dispersant 2-5
2-5 parts of WF-7620B dispersant. Compared with the prior art, the invention has the beneficial effects that:
the two-component epoxy organic anticorrosive paint provided by the invention has the following positive effects:
the special water-based low-VOC paint for the axle provided by the invention adopts a special dispersant and a multi-component thickener, and the prepared paint is good in fastness, oxidation-resistant, green and environment-friendly, and is suitable for large-scale popularization.
Detailed description of the invention
The following examples are intended to further illustrate the invention, but not to limit the scope of the invention. Any changes made in the art upon reading this disclosure are to be considered equivalents thereof.
Example 1
The water-based axle low-VOC special coating comprises the following components in parts by weight:
Figure BDA0002871916310000022
Figure BDA0002871916310000031
the VOC content was tested to be less than 0.2.
