Description
Technical field
The present invention relates to a kind of modified polyurethane resin water paint, more particularly to antifouling, anti-corrosion, antistatic work(
A kind of Graphene-fluorine richness polyurethane resin aqueous functional the coating of energy, belongs to aqueous sapecial coating technical field.
Background technology
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.Requirement of the conventional coating to base protection layer, it is past
It is past to only require that appearance looks elegant, gloss are bright-coloured, and to the no strict requirements of antifouling property of coating.With industrial expansion,
Social environment is increasingly severe, and various pollution sources are flooded with our daily lifes, in the dust, car exhaust gas such as in air
Particulate matter, industrial acid rain etc., these are usually polluted and not easy cleaning to substrate surface, at the same damage coating outward appearance and
Its protective value.
With the continuous enhancing of continuous progressive and people's environmental consciousness of scientific and technological level, to the environmental requirement of coating increasingly
Height, without or less system containing volatile organic matter oneself turn into new developing direction, solvent type resin is just progressively by water-base resin institute
Substitute.Coating is multi-component material, generally comprises solvent, resin, pigment and additive.Property list is comprised only in traditional coating
One resin, its performance receives certain limitation, is likely to result in that structural form itself is good, case hardness is too low, is crosslinked close
Degree is little, the problems such as so as to cause coating not strong for the antifouling property in outside contamination source.
Polyurethane is to be by isocyanates, polyester or PPG and small molecule polyol and polynary amine chain extender
Primary raw material.Polyurethane has the advantages that hardness is big, wear-resistant, adhesion property is excellent, thus is widely used in coating, gluing
The fields such as agent, foamed plastics, ink and rubber, but polyurethane is present, and impact resistance is not good, wet is easy to foaming, general poly- ammonia
Ester insulating properties is high, is also easy to produce electrostatic, and this is restricted its application in some fields.
Fluorine atom radius is small and with very strong electronegativity, therefore it there is shielding protection to act on carbochain, and this causes fluorine
Polymer has excellent heat endurance, weatherability and a chemical inertness, and the low surface tension of uniqueness, low surface free energy,
Low-friction coefficient, this gives fluoropolymer and possesses excellent water and oil repellence, is a class of low-surface-energy material research field
Important polymer.
Graphene has excellent combination property, such as high conductivity, thermal conductivity, high intensity characteristic, and Graphene is
Most thin, the most hard nano material in known world.Graphene is referred to as " dark fund ", is " king of new material ", and it is one that graphite is dilute
Plant by individual layer sp2The two-dimensional sheet material of hydbridized carbon atoms composition.Graphene can be prepared into oxidation after being aoxidized through strong oxidizer
Graphite, oxidized graphite flake layer contains hydroxyl isoreactivity group, and with specific surface area higher, through the Graphene after peroxidating,
Its π-pi-conjugated structure has suffered destruction, and intermolecular Van der Waals force is weak compared with Graphene, and lamella is easily peeled off.In recent years aoxidizing stone
Nano composite material prepared by black alkene shows very superior performance, is increasingly valued by people, its prepare lightweight,
Low cost, high-performance composite materials aspect have wide application potential.
The content of the invention
At present, the resin of single mass can not meet the requirement of Coating Market, Graphene-fluorine richness polyurethane resin
Coating, has had the property of Graphene and fluorine element concurrently, and hardness of paint film and water resistance, antifouling, anti-corrosion, antistatic property have
Very big raising.
A kind of environmentally friendly modified polyurethane resin aqueous functional coatings of present invention exploitation, film has excellent machine
Tool intensity, the performance such as excellent antifouling, anti-corrosion, antistatic.
The present invention combines the advantage of polyurethane resin, is reacted using the hydroxyl in graphene oxide and polyurethane, stone
For chemical bond is connected between black alkene and polyurethane, can stable and uniform be dispersed in resin.
