preparation example 0
[0102] Preparation Example 0: Preparation of Shell Powder
[0103] (1) The washed shells are sequentially calcined in a three-stage gradient, and the specific calcination operation is as follows:
[0104] A1: Calcining at 400°C for 12 minutes;
[0105] A2: Raise the temperature to 500°C at a heating rate of 10°C / min, and keep the temperature for calcination for 22 minutes;
[0106] A3: Raise the temperature to 700°C at a heating rate of 5°C / min, and keep it for calcination at this temperature for 35 minutes. After the calcination is completed, cool it down to room temperature naturally to obtain the calcined shell;
[0107] (2) Pulverize and grind the calcined shells, and pass through a 300-mesh sieve to obtain the shell powder, which is named as BKF.

[0108] Preparation Example 1: Preparation of Modified Shell Powder
[0109] B1: Obtain shell powder BKF according to the same method as above-mentioned preparation example 0, namely implement the following steps:
[0110] (1) The washed shells are sequentially calcined in a three-stage gradient, and the specific calcination operation is as follows:
[0111] A1: Calcining at 400°C for 12 minutes;
[0112] A2: Raise the temperature to 500°C at a heating rate of 10°C / min, and keep the temperature for calcination for 22 minutes;
[0113] A3: Raise the temperature to 700°C at a heating rate of 5°C / min, and keep it for calcination at this temperature for 35 minutes. After the calcination is completed, cool it down to room temperature naturally to obtain the calcined shell;
[0114] (2) crushing and grinding the calcined shells, and passing through a 300-mesh sieve to obtain the shell powder;

According to the method disclosed by the invention, by virtue of special process treatment, shell powder, modified shell powder, and functional coating with a superior performance, and the like are obtained; and the finally obtained functional coating has an outstanding performance on aspects of antibiosis, deodorization, formaldehydedecomposition and the like, an unexpected joint synergistic effect among the components is shown, and a wide actual application value is provided.
Description
technical field [0001] The invention relates to a shell powder, more specifically relates to a shell powder and its preparation method, modification method and application, and belongs to the technical field of functional powder. Background technique [0002] Shell powder is a powder made by processing the shells of various shells. It can be used in various chemical products such as paints, and has certain adsorption and bactericidal functions. [0003] In my country, especially in the southeast coastal areas, a large number of shells are produced every year. On the one hand, this pollutes the environment and causes the waste of stockpiled land. On the other hand, it does not realize waste utilization and wastes potential resources. Therefore, for the comprehensive utilization of shells, not only [0004] A large number of shells can be consumed to protect the environment, and on the other hand, it can turn waste into treasure and realize its deep processing and utilization...
