After galvanizing and powder spraying treatment, the guardrail has strong corrosion resistance, but the coating process of the above treatment method is complicated
Because the curing temperature of the coating film is high, generally curing at 180-190 ° C, the energy consumption is large, and the preparation cost of the coating is high; the drying conditions of the coating equipment are strict, and it needs to be painted in a professional coating field, which is not suitable for on-site construction on the highway and maintenance; at the same time, the leveling of the co

Abstract
The invention discloses super-staining-resistant waterborne coating for a road fence and a preparation method of the super-staining-resistant waterborne coating. The super-staining-resistant waterborne coating is prepared from the following components in parts by weight: 250-300 parts of a styrene-acrylic emulsion, 2-5 parts of a solubilizing assistant, 1-5 parts of an organic silicone powder, 1-5parts of nanometer aluminum oxide, 0.5-2 parts of nanometer zirconium oxide, 0.1-3 parts of nanometer negative ion powder, 0.05-0.5 part of nanometer zinc oxide, 0.1-1 part of silica sol, 0-10 partsof a pigment, 0.1-0.2 part of a PH regulator, 0.1-0.2 part of an antifoaming agent, 2-5 parts of a coalescing agent, 0.3-0.5 part of a dispersing agent, 0.3-0.5 part of a base material wetting agent,5-10 parts of deionized water, and 0.5-1.0 part of a thickener. The super-staining-resistant waterborne coating has the slippery hand feeling and the gorgeous appearance, has a certain self-cleaning effect, prevents marks such as fingerprints and oil stains, is capable of keeping the surface bright and clean, is low in coating surface energy, and has the effects of persistent sterilization and anion release.
Description
technical field [0001] The invention relates to the field of water-based paints, in particular to a super-pollution-resistant water-based paint for road guardrails and a preparation method thereof. Background technique [0002] Highway guardrail is an important facility to maintain highway order and ensure driving safety. On the one hand, it plays a protective role in preventing cars from overturning and rushing out of the highway; . At present, the highway guardrail is in the harsh outdoor environment and has been exposed to sunlight, wind and rain erosion, seasonal temperature changes and environmental media. The anti-corrosion life of many guardrail coatings is greatly shortened, and the decorative appearance is reduced, which seriously reduces the protective performance of the guardrail. . At the same time, with the rapid development of my country's economy, the tonnage of domestic long-distance diesel transport vehicles is increasing, and the unburned hydrocarbons and...
