example 1

[0025]Use hydrochloric acid with a concentration of 1mol / L to adjust the pH of the sodium silicate solution with a mass fraction of 20% to 5.5, stir and react for 20 minutes to obtain a mixed solution, heat the mixed solution to 100°C, and continue to stir and react for 1 hour to obtain a reaction solution. Mix the mass fraction of 10% sodium hydroxide solution with the mass fraction of 20% potassium metaaluminate solution to obtain a precursor solution at a ratio of 1:3:12; Add nickel boride with 2% mass of precursor liquid and lemon juice with 5% mass of precursor liquid, seal the high-pressure hydrothermal kettle, heat up to 180°C under 1.3MPa, conduct hydrothermal reaction for 30h, filter and separate after the hydrothermal reaction is completed The obtained filter residue is a self-made functional filler; the above-mentioned self-made functional filler and nano silicon dioxide are mixed in a mass ratio of 2:1 to obtain a mixed filler, and then the mixed filler, tea polyphe...

Abstract

The invention relates to the technical field of preparation of coatings, in particular to a preparation method of high-adhesion fluorocarbon coating. A base and the aluminum source lithium metaaluminate are added to a self-made silicon source; nickel boride and lemon juice are added during hydrothermal reaction; nickel boride is used as a catalyst, the catalyst and cheating property of organic acids in the lemon juice enable metal ions in aluminum silicon molecular sieve to leave original lattice and enter the organic acids; tea polyphenols and microbes are then used to perform further modification on the molecular sieve and nano silica, so that adhesion of the coating is improved; the nano silica can improve wear resistance of the fluorocarbon coating. Grape wine contains rich organic carboxylic acid and other active ingredients; by adding the grape wine to the fluorocarbon coating, adhesion of the fluorocarbon coating is further improved; phenols and ketones having natural antioxidant action can be added such that the final fluorocarbon coating has significantly improved aging resistance and has a promising application prospect.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a preparation method of a high-adhesion fluorocarbon paint. Background technique [0002] Now our country is in a period of rapid urbanization and industrialization, with a total construction volume of about 2 billion square meters per year. With the development of real estate and architectural decoration industry, the building decoration material industry has also developed rapidly, especially the use of exterior wall paint has increased year by year, and the use of fluorocarbon paint has also increased year by year. Fluorocarbon coatings have become a model of green environmental protection coatings because of their good anti-corrosion, anti-fouling, super weather resistance, chemical resistance, adhesion and other characteristics. At present, fluorocarbon coatings are divided into two types: water-based fluorocarbon coatings and solvent-based fluorocarbon coatings. ...
