Abstract

The invention discloses anti-fouling anti-precipitation dual-component rattan paint. The paint consists of a component A and a component B in the mass ratio of the component A to the component B being (1.5-2) to 1. Modified siloxane is nanoparticles containing Si-O-Si skeleton structures, so that the condition that volatile matters of organic compounds in a polymer in a further oxidation and decomposition course are released can be avoided, and the anti-fouling anti-precipitation dual-component rattan paint has good heat stability, and is easy to functionalize, can be well introduced to an organic matrix for improving the properties of the polymer, and can also generate SiO2 under the condition of oxidation for coating the surface, so that the anti-fouling anti-precipitation dual-component rattan paint can separate oxygen and heat, and the effect of flame resistance is improved.

Description

technical field

[0001] The invention relates to the technical field of rattan paint, in particular to an anti-fouling and anti-scaling two-component rattan paint and a preparation method thereof. Background technique

[0002] Two-component polyurethane paint is composed of hydroxyl-containing water-based resin and -NCO-based cross-linking agent. The two are mixed evenly before construction. The film-forming process is different from solvent-based systems. The initial film-forming process is a physical drying process. Evaporation of water, coagulation of dispersion or emulsion particles, interdiffusion of polymer chains and crosslinking reactions, good coating performance, good hot water resistance, etc., so more research has been done on it;

[0003] However, the main defect of the two-component polyurethane paint is that the curing agent reacts with water to generate various by-products, which cause the loss of the crosslinking ability of the coating film, the shortening of...
