Embodiment 1

[0045] Example 1: Weigh 10g of nano-cerium oxide into a three-necked flask, dilute with 100g of mixed solvent (water:ethanol=1:9), and then add 1% NDZ-201 titanate couple of powder mass to it The coupling agent is fully stirred for 2 hours, heated to 85° C., mixed and stirred and refluxed for 5 hours, and then the mixture is suction filtered, dried, ground, and sieved to obtain modified particles of nano-cerium oxide.

Embodiment 2

[0046] Example 2: Weigh 10g of nano-cerium oxide into a three-necked flask, dilute with 100g of mixed solvent (water:ethanol=1:9), and then add 4% NDZ-401 titanate of powder mass to it The coupling agent is fully stirred for 2 hours, heated to 85° C., mixed and stirred and refluxed for 5 hours, and then the mixture is suction filtered, dried, ground, and sieved to obtain modified particles of nano-cerium oxide.

[0047] Preparation of nano-cerium oxide / epoxy composite coating:

Embodiment 4

[0055] Add 5g of nano-cerium oxide modified according to Example 1 into 69g E51 epoxy resin, 0.5g Anti-Terra-204 dispersant, 0.5g BENTONE27 anti-settling agent and 25g xylene in a container, and stir for 40 minutes; Grind these epoxy resin mixtures to obtain component one of nano-cerium oxide / epoxy composite coating; in another container, dissolve 50g polyamide curing agent in 50g toluene to make nano-cerium oxide / epoxy composite Component two of the coating; add component two to component one in the ratio of component one: component two=100:80, and cure at room temperature for 30 minutes to 7 days to form a nano-cerium oxide / epoxy composite coating.

Abstract

The invention provides nano cerium oxide / epoxy composite paint and a preparation method thereof. The nano cerium oxide / epoxy composite paint comprises epoxy resin, modified nano cerium oxide, an assistant, solvent, a polyamide curing agent and the like. The preparation method comprises the following steps: modifying the nano cerium oxide with titanate; and adding the modified nano cerium oxide into the epoxy resin and the solvent, thus preparing the nano cerium oxide / epoxy composite paint, wherein a coating formed by the nano cerium oxide / epoxy composite paint has favorable corrosion resistance and penetration resistance. The method provided by the invention is applicable to production of the nano cerium oxide / epoxy composite paint; and the nano cerium oxide / epoxy composite paint product provided by the invention can be widely used for transmission equipment, bridges, ships, offshore platforms, underwater coatings, port facilities, surface rust prevention of automobile chassis and antirust primer for outer walls of oil tanks, and can also be used as a chemical anticorrosion coating, an anticorrosion coating for coal mine facilities and the like.

Description

[0001] technical field [0002] The invention relates to a preparation method of a nanometer cerium oxide / epoxy composite coating, which belongs to the technical field of coatings. Background technique [0003] Coatings can be divided into organic coatings and inorganic coatings according to different film-forming substances. Epoxy coatings are the most important type of organic coatings. Suitable for steel surface, antirust primer, also can be used as power transmission equipment, bridges, ships, offshore platforms, underwater coating, harbor facilities, automobile chassis surface antirust, oil tank outer wall antirust primer, and can also be used as chemical anticorrosion Coatings, anti-corrosion coatings for coal mine facilities, etc. [0004] Generally speaking, the surface modification methods of nanoparticles include: surface coverage modification, mechanochemical modification, outer film layer modification, local activity modification, high-energy surface modifi...
