Problems solved by technology

[0019] In our 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 waste of stockpiled land. On the other hand, the waste of shells has not been realized, wasting their potential economic value.

[0094] Preparation Example 0: Preparation of Shell Powder

[0095] (1) The washed shells are sequentially calcined in a three-stage gradient, and the specific calcination operation is as follows:

[0096] A1: Calcining at 400°C for 12 minutes;

[0097] A2: Raise the temperature to 500°C at a heating rate of 10°C / min, and keep the temperature for calcination for 22 minutes;

[0098] 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;

[0099] (2) Pulverize and grind the calcined shells, and pass through a 300-mesh sieve to obtain the shell powder, which is named as BKF.

[0100] Preparation Example 1: Preparation of Shell Powder

[0101] A1: The washed shells are sequentially calcined in a three-stage gradient. The specific calcination operation is as follows:

[0102] A1-1: Calcining at 400°C for 12 minutes;

[0103] A1-2: Raise the temperature to 500°C at a heating rate of 10°C / min, and keep the temperature for calcination for 22 minutes;

[0104] A1-3: 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;

[0105] A2: crushing and grinding the calcined shells, and passing through a 300-mesh sieve to obtain the first shell powder;

[0106] A3: Add diethanolamine and absolute ethanol to n-butyl titanate (the molar ratio of n-butyl titanate to diethanolamine is 1:0.15, and the amount of absolute ethanol can be selected appropriately) to obtain a solution, and then ...

Abstract

The invention provides shell powder putty and a preparation method and application thereof. The shell powder putty is prepared from shell powder, styrene-acrylic emulsion, modified mullite powder, active oxygen diluting agents, organic silane coupling agents, adhesion reinforcing agents, defoaming agents, gel agents, adhesives, composite inorganic micro powder, magnesium borate whiskers, sodium carboxymethylcellulose, heavy calcium carbonate and nano silicon dioxide. According to the shell powder putty, the good stability, adhesion strength, formaldehyde removing capacity, harmful gas removing capacity and appearance quality are achieved through selection and synergy of specific components, usage of the specific preparation method and the like, and therefore the very wide actual application value is achieved in the fields such as building, decorating and coating.

Description

technical field [0001] The invention relates to a material and its preparation method and application, more particularly to a shell powder putty, its preparation method and application, and belongs to the technical field of building decoration materials. Background technique [0002] Putty, also known as filling mud, putty powder, etc., is a decorative material for leveling the surface of the wall. After being stirred with water, it becomes a thick paste paint. It is an indispensable product and process before painting paint. . [0003] Putty is generally applied on the primer or directly on the object, so as to remove the uneven defects on the surface of the object through the plasticity of the putty. remove. Since paint, lacquer and other outer materials need to be coated outside the putty layer, the putty must have many characteristics and requirements such as good adhesion, no cracks during baking, and good air permeability. [0004] With the development of technology...
