Problems solved by technology

Ordinary chlorinated rubber anti-corrosion paint can meet the requirements of general industrial anti-corrosion, that is, good physical and chemical properties, salt spray resistance up to 200-300 hours, but higher requirements for salt spray resistance (such as salt spray resistance 600 hours), resistance to seawater, Ordinary chlorinated rubber anti-corrosion paint cannot meet the requirements when the comprehensive performance requirements such as wear resistance and chemical resistance are higher

Abstract

The invention relates to a seawater-resistant anticorrosive paint, which comprises components in parts by weight as follows: 20-40 parts of 50% chlorinated rubber resin solution, 15-30 parts of 7119 acrylic resin, 0.5-1.0 part of dispersant BYK163, 10-20 parts of zinc chrome, 5-10 parts of A-type titanium dioxide, 1-5 parts of zinc oxide, 5-10 parts of talcum powder, 2-5 parts of 10% BT-38 pregel, 5-10 parts of 50% linseed alkyd resin solution, 5-10 parts of chlorinated paraffin (containing 52% of chlorine), 5-10 parts of dimethylbenzene, and 5-10 parts of butyl acetate. A preparation method of the seawater-resistant anticorrosive paint comprises the steps of preparing the chlorinated rubber resin solution, preparing the pregel, mixing and stirring. The seawater-resistant anticorrosive paint has the beneficial effects that the 50% linseed alkyd resin solution toughens and modifies the chlorinated rubber resin and the acrylic resin to endow excellent resistance against seawater, salt water, salt mist, oil, abrasion and chemicals.

Description

technical field [0001] The invention belongs to coatings, in particular to a seawater-resistant anticorrosion paint and a preparation method thereof. Background technique [0002] Chlorinated rubber anti-corrosion paint is made of chlorinated rubber resin, toughener, pigments, anti-rust pigments, fillers and additives. Products can be divided into two categories: primers and topcoats. The film-forming substance of this product is chemically inert and has good sealing properties. It has good resistance to atmosphere, moisture, salt, alkali and acid, has good outdoor weather resistance, tough coating film, strong adhesion, fast drying, single-component packaging, and convenient construction. Long storage period, no skinning, no caking. It is suitable for the protection of ships, ports, railway facilities, offshore oil production platforms, bridges, petroleum, chemical, smelting, steel equipment, containers, pipelines and concrete surfaces, and plant structures. It is prote...
