Preparation method of carboxyl-terminated bromine-carbon polyester resin fireproof coating used in marine climate

Abstract

The invention relates to a preparation method of a carboxyl-terminated bromine-carbon polyester resin fireproof coating used in the marine climate. The coating comprises the following raw materials in parts by weight: 80-90 parts of carboxyl-terminated bromine-carbon polyester resin, 3.5-4 parts of triethanolamine, 10-15 parts of melamine, 5-10 parts of titanium dioxide, 8-14 parts of expanded perlite, 8-12 parts of hydroxyethyl cellulose, 3-6 parts of sodium methylsilanolate and 4-7 parts of aluminium sulfate. The preparation method comprises the following steps: firstly mixing the carboxyl-terminated bromine-carbon polyester resin and triethanolamine, then adding melamine, titanium dioxide, expanded perlite and hydroxyethyl cellulose, mixing the materials to prepare primary slurry, mixing sodium methylsilanolate and aluminium sulfate, then adding the primary slurry and mixing the materials, finally melt-extruding the mixture with an extruder, and grinding the product in sequence, thus obtaining the coating.

Description

technical field [0001] The invention relates to a fireproof coating, in particular to a marine climate carboxyl bromocarbon terminated polyester resin fireproof coating and a preparation method thereof. Background technique [0002] Polyester powder coatings have good physical and mechanical properties, and can be widely used for decoration and protection of metal surfaces. In marine climates, ships require coatings with high fire resistance, water resistance, and corrosion resistance. Most of the polyester powder coatings on the market It only has excellent performance in fire prevention, but it cannot meet the special requirements of marine climate. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a kind of marine climate carboxyl bromide carbon terminated polyester resin fireproof coating and preparation method which is convenient to manufacture, low in cost, and has good fireproof, water resi...
