A kind of preparation method of marine climate polyetherimide resin waterproof coating

Abstract

The invention relates to a preparation method of a maritime climate polyetherimide resin water-proof coating. The maritime climate polyetherimide resin water-proof coating comprises the following raw materials in parts by weight: 80-90 parts of polyetherimide 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 ssodium methylsiliconate and 4-7 parts of aluminum sulfate. The preparation method comprises the following steps of: firstly mixing the polyetherimide resin and triethanolamine; then adding melamine, titanium dioxide, expanded perlite and hydroxyethyl cellulose, mixing into a raw stock, mixing and blending sodium methylsilanolate and aluminum sulfate, and then adding to the raw stock for mixing; finally sequentially carrying out melt extrusion through an extruder and crushing to obtain the coating.

Description

Technical field [0001] The invention relates to a waterproof coating, in particular to a preparation method of a marine climate polyetherimide resin waterproof coating. Background technique [0002] Polyester powder coatings have good physical and mechanical properties and can be widely used in the decoration and protection of metal surfaces. In marine climates, the coatings require high waterproof, water resistance and corrosion resistance. Most of the polyester powder coatings on the market Only excellent in waterproof performance, but can not meet the special requirements of marine climate. Summary of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a marine climate polyetherimide resin waterproof coating that is convenient to manufacture, low in cost, and has good waterproof, water resistance and corrosion resistance, and a preparation method. [0004] The technical scheme adopted by the present invention is: a m...
