Embodiment 1

[0018] The preparation method of a kind of hydrophobic type graphene solvent-free epoxy underwater curing coating described in the present embodiment is made from the raw material of following percentage by weight:

[0019] Component A

[0020]

[0021] Component B

[0022]

[0023] Preparation method: (1) Put each raw material in component A into the tank one by one, stir rapidly to disperse, and grind to 50 μm to obtain component A. (2) Put each raw material in component B into the tank one by one, stir rapidly to disperse, and grind to 50 μm to obtain component B. (3) Mix component A and component B uniformly according to the weight ratio of 100:38 to obtain a hydrophobic graphene solvent-free epoxy underwater curing coating.

[0024] How to use: Remove floating rust on steel surface, remove dirt on concrete surface, and then brush, roll or scrape the mixed paint on the surface of the substrate.

Abstract

The invention provides a hydrophobic graphene solvent-free epoxy underwater curing coating and a preparation method thereof. The hydrophobic graphene solvent-free epoxy underwater curing coating is prepared from a component A and a component B in the weight ratio being 100:(30-55), wherein the component A comprises raw materials as follows: 35%-50% of epoxy resin, 6%-10% of polysulfide rubber, 2%-8% of petroleum resin, 7%-10% of a reactive diluent, 1%-5% of organic silicon resin, 20%-40% of antirust pigments, 0.2%-6% of an aid and 0.5%-5% of hydrophobic graphene; the component B comprises rawmaterials as follows: 40%-50% of modified phenolic amine, 15%-20% of modified aliphatic amine, 0.5%-15% of an aid and 18%-30% of pigment and filler. The invention provides the hydrophobic graphene solvent-free epoxy underwater curing coating and the preparation method thereof, and the hydrophobic graphene solvent-free epoxy underwater curing coating can be constructed on surfaces of underwater substrates, can be cured quickly and has excellent adhesive force and corrosion resistance.

Description

technical field [0001] The invention relates to a hydrophobic graphene solvent-free epoxy underwater curing coating, in particular to a preparation method of a hydrophobic graphene solvent-free epoxy underwater curing coating. technical background [0002] my country has a long coastline and a vast sea area under its jurisdiction. With the vigorous development of ocean development, marine corrosion and protection has become one of the main problems to be solved in the process of my country's economic development. At present, some special engineering components of marine heavy-duty anti-corrosion, such as offshore oil drilling platforms, trestles, various oil pipelines, wharf steel piles and other large-scale facilities, as well as marine concrete structures, use anti-corrosion coatings for anti-corrosion. If coating anti-corrosion failure occurs, these The components have been soaked in seawater environment for a long time, so that they cannot reach the service life. Moreov...
