Preparation process of nano thermal insulation coating

Abstract

The invention discloses a preparation process of a nano thermal insulation coating. The method comprises the following steps: preparation of nano antimony pentoxide: adding 14-15 parts of antimonous oxide and 19-20 parts of deionized water into a stirring reaction kettle to be stirred, so that the antimonous oxide and the deionized water are fully mixed into a slurry; then heating the slurry to raise the temperature to 90-95 DEG C, after the heating is finished, adding inlet water into the kettle and stirring for 5 to 7 minutes; slowly dropwise adding 11-12 parts of hydrogen peroxide into a mixture after stirring; after hydrogen peroxide is added completely, continuing to stir for 2-4 minutes to fully mix a slurry with hydrogen peroxide; after mixing, heating and refluxing an obtained mixture for 43 to 48 minutes to prepare a white thick paste, slightly cooling the white thick paste, filtering the white thick paste to remove aggregates or block particles in the white thick paste, and drying the obtained white thick paste in an oven at 80-90 DEG C to obtain the nano antimony pentoxide.

Description

technical field [0001] The invention relates to the technical field of coating processing, in particular to a preparation process of a nano-scale thermal insulation coating. Background technique [0002] Paint, what we usually refer to as paint, is just one of them. It refers to the ability to form a thin film on the surface of an object under certain conditions to protect, decorate or other special functions (insulation, rust prevention, mildew resistance, resistance heat, etc.), a class of liquid or solid materials, because most of the early coatings used vegetable oil as the main raw material, so they were also called paints. Now synthetic resins have replaced vegetable oils, so they are called paints. Paints are not liquid, and powder coatings are types of paints. A large category, coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatin...

[0002] Paint, what we usually refer to as paint, is just one of them. It refers to the ability to form a thin film on the surface of an object under certain conditions to protect, decorate or other special functions (insulation, rust prevention, mildew resistance, resistance heat, etc.), a class of liquid or solid materials, because most of the early coatings used vegetable oil as the main raw material, so they were also called paints. Now synthetic resins have replaced vegetable oils, so they are called paints. Paints are not liquid, and powder coatings are types of paints. A large category, coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional products. Engineering materials are an important industry in the chemical industry. There are four main functions: protection, decoration, concealment of product defects and other special functions and enhancement of product value. Since the founding of New China 60 years ago, with the development of various industries in the national economy , as its supporting paint industry, has gradually developed from a very inconspicuous small industry to an indispensable important industry in various fields of the national economy. After several generations of tenacious struggle and pioneering spirit, China has become the second largest paint industry in the world. Production countries and consumer countries have entered the mainstream of the development of the world's coatings industry. The existing coatings have certain defects in use, such as not having functions such as heat preservation, heat insulation, and flame retardancy.
