Abstract
The invention provides a normal-temperature curing FEVE fluorocarbon resin wear-resistant coating which comprises a component A and a component B, wherein the weight ratio of the component A to the component B is (8-12): 1; wherein the component A comprises the following components in parts by weight: 40-60 parts of FEVE fluorocarbon resin; 1-20 parts of alkali metal titanium-based whisker; 20-55 parts of a mixed solvent A; 0.5-2 parts of a dispersing agent; 0.1-2 parts of a defoaming agent; 0.1-2.5 parts of a leveling agent; 0.001-0.01 part of curing catalyst; 0.5-5 parts of an anti-settling agent; wherein the component B comprises the following components in parts by weight: 60-80 parts of aliphatic isocyanate; 20-40 parts of mixed solvent B. The coating has simple construction process, can be prepared into coatings with different thicknesses and appearances by adopting conventional brushing, spraying, rolling, spin coating, napping and other modes, and the obtained coating can be cured at normal temperature and has excellent wear resistance, corrosion resistance and weather resistance.
Description
Technical field
The invention belongs to material surface protection technique field, and in particular to the normal temperature that a kind of wearability is good, hardness is higher is consolidated
Change FEVE fluorocarbon resin wear-resistant paints and preparation method thereof, can meet in warship harbour, extra large construction equipment, oil-gas pipeline, wind-powered electricity generation
The use requirement of the various harsh weather such as blade.
Background technology
Object in atmospheric environment can be corroded by Corrosive, and coating material is inexpensive and effective
Preventive means, but with the development of modern science and technology, the equipment length such as warship harbour, extra large construction equipment, oil-gas pipeline, wind electricity blade
Time works under severe conditions, the high-strength sunlight exposure of such as marine environment, free chloro ion, round the clock moist atmosphere, big temperature
Difference, dust storm, rubble, the sandstorm of wind power plant such as desert, Gobi desert etc., need the combination properties such as high durable, high anti-corrosion, high abrasion badly
Excellent functional coating ensures the long-term normal operation of these equipment.
Fluorocarbon coating is using fluorocarbon resin as film forming matrix, in fluorocarbon resin, because fluorine element electronegativity is strong, activity is low,
And C-F keys bond energy is strong, 484kJ/mol is reached, therefore the C-F bond energys of high bond energy enough protect the C-C keys of low bond energy by helical conformation
Shield is got up, and greatly enhances the stability of main chain, under outside environmental activity, and C-F keys are difficult to be broken, and shows the chemistry of height
Inertia and stability, so fluorocarbon coating has extraordinary weatherability, the corrosion resistance of protrusion, excellent chemical proofing.
Wherein fluoroolefins/ethylene monomer copolymer (FEVE) may be dissolved in organic due to introducing function vinyl monomer in copolymerization
In solvent, normal-temperature reaction solidification is preferable severe rugged environment protective coating material, is widely used in aviation, building, steel construction
With the field such as heavy antisepsis.But pure FEVE coatings belong to organic coating, its abrasion resistance properties is poor, actually be on active service during by
High velocity air, current, sandstone wash away and during the effect such as mechanical force, and the abrasion of coating is quite serious, greatly affected in fact
Border active time.To increase the service life, effective performance of its excellent properties is ensured, it is necessary to lift its abrasion resistance properties.
The content of the invention
Technical problem：In order to solve the defect of prior art, the invention provides a kind of normal temperature cure FEVE fluorocarbon resins
