Description
Technical field
The present invention relates to the fluoropolymer water of a kind of water-based anticorrosive paint, more particularly to a kind of salt fog resistance, weatherability
Property anticorrosive paint, belongs to aqueous functional coatings technical field.
Background technology
According to statistics, the whole world is every year because the metal of rust corrosion is about more than the 20%~40% of annual production, every year because of corruption
The metal for losing and scrapping is up to more than 100,000,000 tons, about 1,000,000,000,000 dollars of caused economic loss；Made every year by metal erosion in China
Into economic loss account for the 1.5%~3.5% of gross national product.Because steel accounts for 95%, Er Qieqi of metal usage amount
In 70% used in the air easily to get rusty, therefore, the anticorrosion of steel has very important significance.
Coating is that daily life takes good care of infrastructure indispensable material, is widely used in building, all kinds of hardware
The field such as part, the decoration of industrial product and machinery, vehicle, ship, woodenware.The annual country have substantial amounts of because of metal corrode and
Destroyed, lose its original performance, caused substantial amounts of metal and scrap, economic loss is huge.People work out a variety of arrange
Applying prevents and suppresses the corrosion of metal, and wherein coating antirust is a kind of effective method.
As the nontoxic regulation of the enhancing of the safe and non-toxic consciousness of people, particularly security for all countries has to volatility in coating system
The strict demand of machine compounds content, promote the development using water paint as the low-contamination type coating of representative.Applied with solvent-borne type
Material is compared, no or seldom (VOC) containing volatile organic matter in water paint, and it has, and safety and environmental protection, construction are flexible, dilute
Agent such as is easy to get at the multiple advantage.
Polyurethane has the advantages that hardness is big, wear-resistant, adhesion property is excellent, but polyurethane has impact resistance not
Good, easy to foaming in case of wet, this is restricted its application in some fields.And the water resistance of acrylic resin paint film forming compared with
It is good, and price is relatively low, therefore acrylic resin is organically combined with polyurethane resin, it is coating resin component
Developing direction.
Chinese patent CN102372999A discloses a kind of polyurethane resin-acrylic resin antirust paint.It mainly by
Following raw materials according is made according to weight proportion stirring：70 parts of polyurethane resins, 36 parts of ethylenediamines, 45 parts of acrylic resins, 12 parts of silicon
Sour potassium sodium, 5 parts of triethanolamines, 15 parts of iron oxide reds, 10 parts of turpentine oil, 65 parts of water, 2 portions of preservatives, 15 parts of kaolin, 3 parts of increasings
Thick dose.The coating of preparation have it is safe and non-toxic, block water, hinder the excellent properties such as oxygen, favorable rust preventing effect, drying time be short.But it is poly-
Urethane resin uses physical mixed with acrylic resin, and its compatibility and crosslink density are not ideal enough.
At present, the resin of single property can not meet the requirement of Coating Market, fluorochemical urethane modified acroleic acid tree
Fat water paint, the property of polyurethane and fluorine atom is had concurrently, crosslink density is high and its surface tension is low, is unfavorable for polluting
Thing is attached to surface, while introduces the relatively low acrylic resin of price, makes it have good economical and practical value.
The content of the invention
Present invention aims to provide a kind of fluoropolymer water-based anticorrosive paint.
Because the fluorine atom in fluoropolymer is along carbochain Spiral distribution, due to the other first sub-prime radiuses of fluorine atom radius ratio
It is small, carbochain can be closely encased and flexed outward, play shielding protection effect, improve the stability of C-C backbone structures,
Assigning fluoropolymer has excellent durability and corrosion resistance.Not only improve the resistance to saltfog of film, corrosion resistance and anti-ageing
The property changed, and there is hydrophobic self-cleaning anti-stain characteristic energy.The present invention uses to improve ageing-resistant, resistance to saltfog and corrosion resistance
