AI Technical Summary

Problems solved by technology

Existing marine anti-corrosion repair coatings are mainly solvent-based and water-based. Among them, solvent-based marine anti-corrosion repair coatings are not environmentally friendly because they contain solvents, and because solvents need a certain amount of time to volatilize, so solvent-based marine anti-corrosion repair coatings cannot achieve rapid repair
Water-based marine anti-corrosion repair coatings are environmentally friendly because they contain water, but because water volatilization takes longer, water-based marine anti-corrosion repair coatings cannot achieve rapid repair

Embodiment 1

[0058] A kind of LED-UV cold light curing quick repair coating and its preparation method:

[0059] First, the following components:

[0060] Nano titanium powder (average particle size 40nm) 45%;

[0061] Nano powder super dispersant Solspers-390005%;

[0062] HEMA: 50% hydroxyethyl methacrylate monomer;

[0063] In the dust-free workshop, the production is put into a closed dispersion barrel according to the formula ratio, and then the MasterMix high-speed dispersing machine (with double suction cups for the dispersion plate) of Netzsch Machinery Instrument Co., Ltd. of Germany is used to adjust the distance between 2000 m / min and 3000 m / min Stir and disperse at high speed for 1 hour to ensure uniform mixing;

[0064] Put the high-speed dispersed organic-inorganic nano hybrid material dispersion into the nano-level circulating bead mill Zeta? RS of Netzsch Machine Instrument Co., Ltd., Germany, and use the particle size 0.1 produced by Netzsch Machine Instrument Co., Ltd. mm ZetaBead...

Abstract

The invention relates to a paint and a preparation method thereof, specifically to an LED-UV cold light-cured rapid-repairing paint especially applicable to anticorrosion of marine ships, and a preparation method thereof. The LED-UV cold light-cured rapid-repairing paint is characterized by comprising the following components: 25 to 55% of LED-UV resin, 10 to 25% of LED-UV monomer, 10 to 14% of LED-UV photoinitiator, 0.05 to 0.1% of LED-UV polymerization inhibitor, 0.3 to 0.8% of LED-UV antifoaming agent, 0.05 to 0.2% of LED-UV substrate wetting agent, 0.6 to 1% of LED-UV leveling agent, 0.1 to 0.5% of LED-UV dispersant, 1.5 to 7.5% of filling material, 0.2 to 0.6% of LED-UV high-molecular organic wax powder and 5 to 50% of LED-UV organic-inorganic nanometer hybrid material. Compared with the prior art, the LED-UV cold light-cured rapid-repairing paint provided by the invention has the advantages of high hardness, good wear resistance, a fast curing speed, resistance to corrosion, energy conservation, environmental protection, low cost, etc.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, specifically to a LED-UV cold light curing method with fast curing speed, good coating performance, high wear resistance, high seawater corrosion resistance, energy saving and environmental protection, and is especially suitable for anticorrosion of marine ships. Quick fix paint and method for making same. Background technique [0002] As we all know, my country is a large ocean country with more than 18,000 kilometers of coastline, rich marine resources and a thriving marine industry. However, the marine environment is very harsh and highly corrosive. Marine corrosion and protection will be an important issue that needs to be solved urgently in my country's economic development. . Moreover, in the process of shipbuilding, the cost of coatings is second only to steel plates, and the market is vast. With the rise of my country's shipbuilding industry, more and more businesses are opti...
