Abstract

The invention discloses a nanometer functional coating and a preparation method thereof. The nanometer functional coating consists of the following components in parts by weight: 45-55 parts of unsaturated polyester, 35-50 parts of polyester resin, 30-40 parts of 5-50 parts of, 1-3 parts of a dispersing agent, 0.4-0.7 part of silicone oil, 2-6 parts of tri-glycidyl isocyanurate and 4-8 parts of a dicyandiamide curing agent. Since the nanometer functional coating contains nanometer-scale titanium dioxide, the aggregation effect is lowered and the film-forming property is excellent, and therefore the nanometer functional coating has strong adhesive force and excellent heat-resisting and water-proof properties and can be used in severe environments such as the open air.

Description

technical field [0001] The invention relates to a nano functional coating, in particular to a nano functional coating and a preparation method thereof. Background technique [0002] Due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles, they exhibit characteristics that conventional materials do not have in terms of magnetism, light, electricity, and sensitivity. Therefore, nanoparticles have broad application prospects in magnetic materials, electronic materials, optical materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. Generally speaking, nano-coatings must meet two conditions: first, at least one phase in the coating has a particle size in the range of 1-100nm; secondly, the presence of nano-phases can significantly improve the performance of the coating or have new features. function. [0003] Although the comprehensive performance of the existing all-round p...
