preparation example 1

[0074] Preparation Example 1: Preparation of Modified Shell Powder

[0075] (1) The washed oyster shells are sequentially calcined in a three-stage gradient. The specific calcining operation is: calcining at 400°C for 12 minutes, then raising the temperature to 500°C at a heating rate of 10°C / min, and heating at this temperature Calcining at low temperature for 22 minutes; finally, heating up to 700°C at a heating rate of 5°C / min, and holding and calcining at this temperature for 35 minutes; after the calcination, naturally cool to room temperature to obtain calcined shells;

[0076] (2) crushing and grinding the calcined shells, and passing through a 300-mesh sieve to obtain shell powder;

[0077] (3) Add diethanolamine and absolute ethanol to n-butyl titanate (wherein the molar ratio of n-butyl titanate to diethanolamine is 1:0.15, the amount of absolute ethanol can be properly selected), to obtain a solution, Then ultrasonically disperse for 25 minutes to obtain a transpar...

preparation example 11

[0080] Preparation Example 1.1: Except modifying step (1) of Preparation Example 1 to "calcine the cleaned oyster shells, the specific calcining operation is: calcining at 400°C for 119 minutes; after the calcination, cool naturally to room temperature to obtain Except for the "shell" after calcination, other operations were unchanged, that is, the three-stage gradient calcination was not carried out, but only the original total time of calcination at 400 ° C. The obtained modified shell powder was named DBK1.

Abstract

The present invention relates to an environmentally friendly shell powder functional coating, a preparation method therefor and uses thereof. The coating comprises: bisphenol A-epon, modified shell powder, vegetable extract, propyl silicone emulsion, a nano additive, a modified organic micro powder agent, a surfactant, dioctylphthalate, 3, 3'-(4-trifluoromethyl methyl)-bi-4-hydroxy coumarin, 2,2,4-amino trimethyl-1,3-isoprene glycol mono iso-butyl methacrylate, butyl acetate, ethanol, trimethylol propane triacrylate, N-ammonia amino ethyl piperazine, polydimethylsiloxane and deionized water. In the present invention, by modification of a variety of components and materials, selection and collocation of specific components and a specific preparation method, the variety of components exert a synergistic effect, so as to make the prepared coating have significant antimicrobial, environmental-cleaning and wear-resisting properties. The coating has a huge application potential and extensive value in industrial production.

Description

technical field [0001] The invention relates to a coating and its preparation method and application, more specifically to an environmentally friendly shell powder functional coating, its preparation method and application, and belongs to the technical field of coatings. Background technique [0002] Paint is a functional chemical preparation that can be applied to the surface of an object to protect or decorate it. It can usually form a firmly adherent film with the object to be coated and exhibit a variety of protective functions. [0003] With the advancement of science and technology, the concept of environmental protection has been deeply rooted in the hearts of the people, and people pay more and more attention to products that meet the words "green" and "healthy", and pay more and more attention to the functional requirements of products. This is because a single function is difficult to meet the general needs of people, and products with more health-added value can f...
