Example Embodiment

The preparation method of the anti-corrosion, wear-resistant, anti-freeze and adhesive bottom surface all-in-one coating provided by the present invention includes the following steps:

Preparation of component A: heat the amino-terminated polyether and fluorine-containing siloxane respectively to 100℃~120℃ for vacuum dehydration; mix isocyanate with anhydrous butyl acetate, heat up to 40℃~50℃ and start dripping after vacuum dehydration After the addition of the amino-terminated polyether and fluorine-containing siloxane, the mixture is heated to 80°C~90°C and kept for 1h~3h, the reaction is ended, the temperature is lowered to 40°C~50°C, and the product is obtained after discharge;

Preparation of component B: first mix and disperse dispersant, solvent and nano antifreeze adhesive material; then mix hindered aliphatic secondary amine, pigment filler, thixotropic agent and solvent, disperse, stir evenly, and grind to fineness ≤ 50μm; Finally, add the ultraviolet absorber nano ant...

Example Embodiment

Example 1:

1) Preparation of component A: 650Kg of amino-terminated polyether (Eastman) with a molecular weight of about 2000 and 50Kg of amino-terminated fluoropolysiloxane (molecular weight of 1800-2200) are heated to 120°C for vacuum dehydration;

Weigh 200Kg of isophorone diisocyanate (Bayer) and 160Kg of anhydrous butyl acetate, mix them evenly, heat up to 45°C and add dropwise the amino-terminated polyether and amino-terminated fluorine-containing polysiloxane after vacuum dehydration. After the addition, the temperature is raised to 80°C and kept for 2h, the reaction is ended, and the temperature is lowered to 45°C for discharging and packaging.

Abstract

The invention provides an antiseptic wear-resisting freezing adhesion-resisting one coat paint which comprises a component A and a component B, wherein the component A comprises the following materials in percentage by weight: 10-40% of isocyanate, 30-75% of amine terminated polyether, 1-15% of fluorine-containing siloxane and 5-25% of anhydrous butylacetate; and the component B comprises the following materials in percentage by weight: 15%-55% of steric hindrance type alkyl secondary amine, 1%-15% of nano freezing adhesion-resisting material, 10%-55% of pigment and filler, 0.5%-2.5% of dispersing agent, 0-2% of thixotropic agent, 0-3% of ultraviolet absorber and 5%-30% of solvent. The antiseptic wear-resisting freezing adhesion-resisting one coat paint provided by the invention is double-component paint comprising a curing agent component and an auxiliary component; and a spraying process is mainly adopted, so that the formed functional coating has the advantages of good antiseptic effect, abradability and freezing adhesion resistance, thus the paint is especially suitable for occasions in which requirements on wear-resistance, corrosion resistance and freezing adhesion resistance are high, such as heavy-duty vehicle coating, wind turbine blades and the like.

Description

A kind of anti-corrosion, wear-resistant, anti-freezing, anti-freeze, sticky bottom and surface all-in-one coating and preparation method thereof technical field The invention relates to the field of coatings, in particular to an anti-corrosion, wear-resistant, anti-freezing, anti-freezing and bottom-surface-integrated coating and a preparation method thereof. Background technique At present, most of the existing domestic anti-corrosion coating systems use primers, intermediate paints, top coats or composite anti-corrosion coating systems of primers and top coats. The main function of the primer is to lay a good foundation on the substrate, which has good adhesion to the substrate and has anti-rust performance; the main function of the intermediate paint is to increase the film thickness, so as to play a more effective shielding effect, and to make the The surface is smooth, which is conducive to topcoat coating; the main function of the topcoat is to prevent harmful corro...
