Problems solved by technology

However, the nano-coatings in the prior art are not easy to disperse, dry slowly, have weak adhesion, and are easy to agglomerate and fall off, so they cannot be widely used.
[0003] In view of the shortcomings of slow drying and weak adhesion of nano-coatings in the prior art, there is an urgent need for a nano-coating or a nano-coating construction method that can solve the above problems

Abstract

The invention provides a nano coating material composition and a construction method thereof, and relates to the field of coating materials. The nano coating material composition comprises a main base material, a curing agent and a diluent, wherein the main base material comprises the following raw materials in percentage by mass: 55-63% of an acrylic resin, 15-25% of titanium dioxide, 8-12% of ethanol, 8-12% of ethyl acetate, 1-3% of an inert nano material and 1-2% of a surfactant. The construction method comprises the following steps: cleaning the surface of a base material; mixing, stirring and standing the main base material, the curing agent and the diluent, uniformly brushing the mixture on the base material, baking, and polishing; brushing finishing paint, and baking; and finally carrying out normal-temperature maintenance on the base material coated with the coating material and the finishing paint. According to the invention, the coating material has quick-drying property, the construction method adopts five times of painting, the thickness requirement of the coating material can be met, baking is performed after each time of painting, the drying speed of the coating material can be increased, and the adhesive force of the coating can be improved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a nano coating composition and a construction method thereof. Background technique [0002] Coating is a kind of decorative material, including many kinds, such as interior and exterior wall building materials, floor coating materials, steel structure anticorrosion materials and other functional coatings, etc. With the rapid growth of China's national economy and the continuous improvement of people's living standards, China my country's paint production and paint consumption are growing at a rapid rate, and it is currently the second largest paint consumer in the world. With the development of various industries, global climate change and the increasingly tense resources and energy, environmental protection is becoming more and more important. Attention, countries around the world have successively formulated strict environmental protection regulations and policies to encourage and promote...
