Embodiment Construction
[0033] The present invention is described in further detail below in conjunction with embodiment.
[0034] The formulations of Examples 1-6 are shown in Table 1, rows 1-12.
[0035] Preparation:
[0036] Preparation of component A: After mixing the pigment and filler with liquid epoxy resin, use a three-roller to grind until the particle size of the pigment and filler particles is โค30 microns, then add white carbon black, stir evenly, add polymer hollow microspheres, and then Stir well, filter and pack.
[0037] Preparation of group B: Weigh the two types of curing agents, hydrophilic and lipophilic, according to the predetermined mass ratio, mix, stir evenly, and pack.
[0038]Application test: Weigh 1kg of prepared component A and 0.15kg of component B, mix well, and apply on the underwater metal and concrete structures. Both have good film-forming properties (visual inspection) and adhesion (the test paint is coated on the rust-removed steel plate, and it is evaluated by...

Abstract
The invention discloses an underwater epoxy resin coating and a preparation method thereof. The underwater epoxy resin coating consists of a component A and a component B, wherein the component A is a composition of liquid epoxy resin, polymer hollow microspheres, white carbon black, pigment and filler; the component B is a compound curing agent blended by hydrophilic amine curing agent and oleophilic curing agent; in the component A, the mass ratio of the liquid epoxy resin to the polymer hollow microspheres to the white carbon black to the pigment and filler is 60-70: 0.05-0.1: 2-6: 30-40, and the mass sum of the components is 100; and in the component B, the mass ratio of the hydrophilic amine curing agent to the oleophilic curing agent is 1: 3-4. The mass ratio of the component A to the component B is 1: 0.25-0.35. The coating has excellent adhesive force on wet surface of underwater metallic structure and nonmetallic structure materials; the coating has good leveling property, good film formation property and smooth coating, and can form a thick film at one time; and the formed film has good protection effect on the surface of the coated material.
Description
technical field [0001] The invention relates to an epoxy resin coating and a preparation method thereof, in particular to an underwater epoxy resin coating and a preparation method thereof. Background technique [0002] With the continuous development of offshore oil mining industry, ports, hydroelectric power stations and shipbuilding industry, many engineering structures in the marine environment, such as drilling equipment, drilling platforms, offshore oil and gas storage tanks, support frames for pipelines, trestles, steel Pile, ship bottom and ship interior cabin, etc., due to being submerged in seawater all the year round, or being eroded by tidal fluctuations and splashes, marine organisms and some moving objects, the original anti-corrosion layer of the structure is damaged and rusted, and these The structure is difficult to move to land for repairs. In addition, structural engineering in fresh water such as dikes, reservoirs, sluices, underwater pipelines, etc....
