Nano rare earth oxide modified functional coating and preparation method thereof

Abstract

The invention discloses a nano rare earth oxide modified functional coating which comprises the following components in parts by weight: 1-3 parts of nano rare earth lanthanum strontium manganese oxide, 10-20 parts of an ethanol water solution, 0.5-3 part of a silane coupling agent, 50-70 parts of epoxy resin, 30-50 parts of a diluent, 0.3-3 part of modified potassium magnesium titanate, 50-90 parts of a bio-based curing agent and 0.05-0.1 part of an auxiliary agent. The adhesive force, the toughness and the impact resistance of the coating are relatively high, and the preparation is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a functional paint modified by nanometer rare earth oxides and a preparation method thereof. Background technique [0002] The method of coating coverage is considered to be an effective way to reduce metal wear and corrosion in complex environments. Among the currently widely used coatings, the use of traditional oil-based coatings accounts for about 50%, but in some harsh operating environments It is difficult to meet the application requirements, so it is urgent to change this state. Due to its unique optical, electrical and magnetic properties, nanocomposite coatings made after adding to traditional coatings can have anti-radiation, anti-static, and antibacterial properties. , anti-aging and other special functions. Traditional coatings have the problems of single function and difficult to meet the application requirements in harsh working environments,...

[0002] The method of coating coverage is considered to be an effective way to reduce metal wear and corrosion in complex environments. Among the currently widely used coatings, the use of traditional oil-based coatings accounts for about 50%, but in some harsh operating environments It is difficult to meet the application requirements, so it is urgent to change this state. Due to its unique optical, electrical and magnetic properties, nanocomposite coatings made after adding to traditional coatings can have anti-radiation, anti-static, and antibacterial properties. , anti-aging and other special functions

Traditional coatings have the problems of single function and difficult to meet the application requirements in harsh working environments, and the coating prepared by physical mixing method has poor dispersion and a large number of micropores, which seriously affects the protective performance of the coating. In view of this, it is necessary Make improvements to traditional functional coatings and their preparation methods
