Problems solved by technology

[0003] The current fluorocarbon paint is mainly solvent-based, and because the solvent-based fluorocarbon paint contains high VOC, the solvent will be directly volatilized in the air during construction and cannot be recycled, resulting in waste of resources, polluting the environment, and causing some harm to construction workers. Toxic, implementing tools are difficult to clean
In addition, the paint film of solvent-based fluorocarbon paint is dense, has poor air permeability, and is prone to local blistering
On the other hand, the weather resistance, stain resistance and aging resistance of latex paint in the prior art can not meet the needs of use

Embodiment 1

[0021] A kind of fluorocarbon paint and preparation method thereof, comprise the raw material of fluorocarbon paint and preparation method, by weight percentage, the raw material of described fluorocarbon paint is as follows:

[0022]

[0023] The rest is deionized water.

[0024] A kind of preparation method of fluorocarbon paint, concrete operation steps are:

[0025] Add deionized water, dispersant, defoamer, titanium dioxide, and fluorocarbon resin to the reaction kettle in order for each component in the formula to mix. The stirrer in the mixing kettle should be stirred and dispersed at a speed of 1500r / min for 30 minutes. , and then sequentially add butyl acetate, hydrophobic agent, leveling agent, HDI isocyanate, stir and disperse at a speed of 1200r / min for 30min until the particle size is 35um, the finished fluorocarbon paint can be obtained, and finally canned. Components in the present invention all adopt existing products, which can be the product models listed...

Embodiment 2

[0033] Same as Example 1, the difference is:

[0034] The mass percentages of fluorocarbon resin, leveling agent, defoamer, titanium dioxide, butyl acetate, dispersant, HDI isocyanate, and hydrophobic agent are: 47%, 1%, 3%, 18.5%, 11.5%, 2% , 16%, 1%.

Embodiment 3

[0036] Same as Example 1, the difference is:

[0037] The mass percentages of fluorocarbon resin, leveling agent, defoamer, titanium dioxide, butyl acetate, dispersant, HDI isocyanate, and hydrophobic agent are: 45.5%, 2%, 4%, 20%, 10%, and 1.5% , 15.5%, 1.5%.

Abstract

The invention discloses fluorocarbon paint and a preparation method thereof, and the fluorocarbon paint is characterized by comprising the following components in percentage by weight: 44%-47% of fluorocarbon resin, 1%-2% of a flatting agent, 3%-4% of a defoaming agent, 8%-20% of titanium dioxide, 10%-12% of butyl acetate, 1%-3% of a dispersing agent, 15%-17% of HDI (hexamethylene diisocyanate) isocyanate, 1%-2% of a hydrophobic agent and the balance of deionized water; the hydrophobic agent is added into the paint, the hydrophobic agent is a water-based cationic solution of polysilane, a special water-resistant structure can be formed on the surface of a paint film to enable the surface to have extremely strong hydrophobic property, waterproof and hydrophobic effects, and the odor-maskingeffect is improved, so that the VOC content is low, and the environment-friendly property is strong.

Description

technical field [0001] The invention relates to the field of paint chemical industry, in particular to a fluorocarbon paint and a preparation method thereof. Background technique [0002] Fluorocarbon coatings, also known as fluorocarbon coatings, fluorine coatings, fluororesin coatings, etc., refer to coatings with fluororesin as the main film-forming substance. Among all kinds of coatings, fluororesin coatings have particularly superior properties, such as weather resistance, heat resistance, low temperature resistance, and chemical resistance, due to the high electronegativity of the introduced fluorine element and the strong bond energy of carbon and fluorine. , and has a unique non-stick and low friction. [0003] The current fluorocarbon paint is mainly solvent-based, and because the solvent-based fluorocarbon paint contains high VOC, the solvent is directly volatilized in the air during construction and cannot be recycled, resulting in waste of resources, polluting t...
