preparation example Construction

[0056] A preparation process for an antirust coating for ship decks, comprising the following steps:

[0057] Step 1. Grinding and blasting the surface of the ship's deck until the derusting level of the steel surface of the ship's deck reaches Sa3 level;

[0058] Step 2. Preparation of pre-dispersion: in ethanol aqueous solution, add water-based leveling agent, water-based wetting agent and corrosion inhibitor sequentially under the condition of 1000r / min with a high-speed mixer, and the feeding interval is 5min, and continue 1000r / min after all addition Stir for 20-24min, then use ultrasonic treatment for 15-18min;

[0059] Step 3. Preparation of anti-rust primer: under constant stirring at 500r / min, add half of the anti-rust filler into the silicone acrylic emulsion, then add 1 / 4 of the pre-dispersion and 1 / 4 of the dispersant, and finish adding Finally, continue to stir at 500r / min for 25-30min, transfer to sand milling equipment, grind until the slurry fineness is ≤35μm,...

Abstract

The invention discloses a rust-proof coating for a ship deck. The rust-proof coating is prepared from, by weight, 30-40 parts of silicone acrylic emulsion, 50-60 parts of acrylic emulsion, 2.5-3 partsof polyethylene wax emulsion, 28-34 parts of fluoro-silicon emulsion, 12-16 parts of anti-rust pigments, 3-5 parts of fillers, 2-3 parts of nano-silicon dioxide, 3-4 parts of corrosion inhibitors, 2-3 parts of dispersing agents, 2-3 parts of defoaming agents, 1.5-2 parts of waterborne leveling agents, 1.5-2 parts of waterborne wetting agents and 8-10 parts of ethanol water. The invention furtherdiscloses a preparation process of the rust-proof coating for the ship deck. According to the coating, the corrosion inhibitors and the anti-rust pigments are added, a bottom layer, a middle layer anda surface layer have different structures are matched each other, so that the prepared coating has good hydrophobicity, water resistance can reach 62d, acid and alkali resistance can reach 35d, saltfog performance can reach 38d, and the coating has good corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of ship rust prevention, and in particular relates to a ship deck antirust coating and a preparation process thereof. Background technique [0002] A ship is composed of many parts. According to the function and use of each part, it can be comprehensively summarized into three parts: hull, ship power plant, and ship electrical. The hull is the basic part of the ship, which can be divided into the main part and the superstructure part. The main part generally refers to the part below the upper deck. It is a hollow body with a specific shape surrounded by the hull (bottom and side) and the upper deck. It is a key part to ensure that the ship has the required buoyancy, navigating performance and hull strength. . The hull is generally used for arranging power plants, loading cargo, storing fuel and fresh water, and arranging various other compartments. [0003] In order to ensure the strength of the hull, imp...
