Carboxyl-terminated bromine carbon polyester resin fire-retardant coating used in desert climate and preparation method of fire-retardant coating

Abstract

The invention relates to a carboxyl-terminated bromine carbon polyester resin fire-retardant coating used in desert climate and a preparation method of the fire-retardant coating. The carboxyl-terminated bromine carbon polyester resin fire-retardant coating is prepared from the following raw materials in parts by mass: 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, 2-8 parts of an ionic chain extender capable of forming hydrophilic groups and having an active hydrogen and 1-10 parts of a silane coupling agent. The preparation method comprises the following steps of firstly mixing carboxyl-terminated bromine carbon polyester resin, triethanolamine, the ionic chain extender capable of forming hydrophilic groups and having activated hydrogen and the silane coupling agent, adding and mixing melamine, titanium dioxide, expanded perlite and hydroxyethyl cellulose and sequentially carrying out melt extrusion by virtue of an extruder and grinding to obtain the coating.

Description

technical field [0001] The invention relates to a fireproof coating, in particular to a fireproof coating of a carboxyl bromocarbon terminated polyester resin in a desert climate 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 desert climates, equipment requires coatings with high fire resistance, high temperature resistance, and wind erosion resistance. Polyester powder coatings currently on the market Most of them only have excellent performance in fire prevention, but they cannot meet the special requirements of desert climate. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a kind of desert climate carboxyl bromide carbon terminated polyester resin fireproof coating and preparation method which is convenient to manufacture, low in c...
