preparation example Construction

[0033] As another preferred version of the present invention, a method for preparing a water-based one-component fluorocarbon paint comprises the following steps:

[0034] Step 1: Extract water, dispersant and pigments into the container, and rotate at 4000 rpm for 30 minutes;

[0035] Step 2: When the fineness of the particles in the container is less than or equal to 20 nanometers, reduce the stirring speed, add water-based one-component fluorocarbon emulsion, water-based nano-titanium dioxide, water-based paint enhancer, various additives and film-forming agent DPNB in ​​sequence, and then use 2000 rpm rotation for 5-10 minutes;

[0036] Step 3: After high-speed dispersion, add various thickeners through low-speed stirring to adjust the viscosity of the solution;

[0037] Step 4: Adjust the pH range of the solution to 8-9.

[0038] The emulsion adopts water-based fluorocarbon emulsion 43011 from Changxing Company in Taiwan, China. The use of water-based nano-titanium diox...

Abstract

The invention discloses water-based single-component fluorocarbon paint and a preparation method thereof, belonging to the field of paint chemical industry. The invention aims to overcome the problemsthat conventional solvent-based fluorocarbon paint contains high VOC, resources are wasted and environment is polluted due to the fact that a solvent is directly volatilized in air when the solvent-based fluorocarbon paint is applied, and a paint film formed by the solvent-based fluorocarbon paint has poor water boiling resistance, gloss and color retention performance, hardness and adhesive force o. According to a technical scheme in the invention, the water-based single-component fluorocarbon paint comprises water, a pigment and filler, a water-based single-component fluorocarbon emulsion,water-based nanometer titanium dioxide, auxiliaries and the film-forming agent DPNB. The fluorocarbon paint of the invention has the characteristics of low surface tension, weather resistance, heat resistance, stain resistance and the like, is extremely low in VOC content, and meets the requirements of sustainable development of the modern society.

Description

technical field [0001] The invention belongs to the field of paint chemical industry, in particular to a water-based one-component fluorocarbon paint and a preparation method thereof. Background technique [0002] Fluorocarbon coatings refer to coatings with fluororesin as the main film-forming substance; also known as fluorocarbon coatings, fluorine coatings, fluororesin coatings, etc. Among all kinds of coatings, fluororesin coatings have particularly superior properties due to the high electronegativity of the introduced fluorine element and strong carbon-fluorine bond energy. Weather resistance, heat resistance, low temperature resistance, chemical resistance, and has unique non-stick and low friction properties. After decades of rapid development, fluorine coatings have been widely used in various fields of construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry and household goods. [0003] At present, the applicati...
