Modified asphalt severely-waterproof anticorrosive boat-bottom fluorescent paint and preparation method thereof

Abstract

The invention discloses modified asphalt severely-waterproof anticorrosive boat-bottom fluorescent paint. The modified asphalt severely-waterproof anticorrosive boat-bottom fluorescent paint is prepared from the following raw materials in parts by weight: 6-9 parts of methyl MQ silicon resin, 10-14 parts of chlorinated rubber, 4-6 parts of diamidocyclohexane, 0.4-1.0 part of ethylene-propylene copolymer, 0.3-0.7 part of m-phenylene dibenzoate, 0.6-1.0 part of tolylfluanid, 1-2 parts of thiocarbanilide, 32-35 parts of modified asphalt, 8-12 parts of modified waste sodium silicate-bonded sand, 1-2 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 2-4 parts of cuprous oxide, 2-4 parts of fluorescent powder, 1-3 parts of phytic acid, 7-9 parts of a 200# coal tar solvent, 4-6 parts of dimethyl benzene and 4-6 parts of butyl acetate. According to the modified asphalt severely-waterproof anticorrosive boat-bottom fluorescent paint disclosed by the invention, the chlorinated rubber and the modified asphalt are added together to improve the corrosion resistance, the adhesion, the flame resistance, the insulation and the weather resistance of the paint, so that the paint is severely waterproof and anticorrosive and used as the boat-bottom paint; the added methanesulfenamide can be used for reducing attachment of aquatic organisms and reducing the consumption of fuel, and the fluorescent powder is added to the bottom of the boat to increase identification degree and reduce loss. Moreover, the waste sodium silicate-bonded sand is modified, so that not only is pollution to environment reduced, but also the fire resistance and the fireproof performance of the paint are increased, and thus, the quality of the paint is further improved.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a modified asphalt heavy waterproof anti-corrosion ship bottom fluorescent paint and a preparation method thereof. Background technique [0002] Ship bottom paint is soaked in seawater for a long time, and is subject to the electrochemical corrosion and erosion of seawater. When the ship is moored in the harbor, it will also be threatened by marine biofouling. Since ships usually use sacrificial anodes or applied current for cathodic protection, the entire underwater area of ​​the hull will become a cathode, which is alkaline due to the action of excessive OH ions, so the bottom of the ship must have good water resistance, alkali resistance, and abrasion resistance. The outer coating must also have good fouling resistance against marine biofouling. Therefore, marine paint is required to have good adhesion, good water resistance, chemical resistance and abrasion resista...

Problems solved by technology

Water glass is colorless, odorless, and non-toxic, and there is no irritating or toxic gas overflow during the casting process. However, in the past, water glass was added in a large amount and its collapsibility was poor. At the sand cleaning site, silicon dust flew up, causing silicon dust pollution. , the old sand is difficult to regenerate, and a large amount is discarded, causing alkaline pollution to the environment
