Embodiment 1

[0032] A preparation process of scrub-resistant diatom mud for interior wall decoration, comprising the following steps:

[0033] (1) Screening diatomaceous earth:

[0034] (1) Add the diatomite raw material into the crushing tank, and use a physical method to feed high-pressure gas. Under the action of strong air flow, the diatomite raw material is impacted in the crushing tank to achieve crushing, reaching 2000 mesh;

[0035] (2) Use the free fall method to screen the crushed diatomite, and collect the diatomite after the diatomite falls for 60 seconds due to the effect of gravity;

[0036] (2) Preparation of modified latex powder:

[0037] (1) First add 200L of water to the reaction kettle, add 2kg of alkylphenol polyoxyethylene ether into the container under stirring conditions and emulsify, then heat the emulsified mixture to 60°C, and then add 80kg of laurel acid and stir until completely melted, then add 40kg of magnesium hydroxide powder and 1.8kg of zinc oxide powde...

Embodiment 2

[0046] A preparation process of scrub-resistant diatom mud for interior wall decoration, comprising the following steps:

[0047] (1) Add the diatomite raw material into the crushing tank, and use a physical method to feed high-pressure gas. Under the action of strong air flow, the diatomite raw material is impacted in the crushing tank to achieve crushing, reaching 2100 mesh;

[0048] (2) Use the free fall method to screen the crushed diatomite, and collect the diatomite after the diatomite falls for 60 seconds due to the effect of gravity;

[0049] (2) Preparation of modified latex powder:

[0050] (1) First add 250L of water to the reaction kettle, add 3kg of alkylphenol polyoxyethylene ether into the container under stirring conditions and emulsify, then heat the emulsified mixture to 66°C, and then add 85kg of laurel acid and stir until completely melted, then add 43kg magnesium hydroxide powder and 2.2kg zinc oxide powder to the mixed solution containing lauric acid, st...

Embodiment 3

[0059] (1) Add the diatomite raw material into the crushing tank, and use a physical method to feed high-pressure gas. Under the action of strong air flow, the diatomite raw material is impacted in the crushing tank to achieve crushing, reaching 2200 mesh;

[0060] (2) Use the free fall method to screen the crushed diatomite, and collect the diatomite after the diatomite falls for 60 seconds due to the effect of gravity;

[0061] (2) Preparation of modified latex powder:

[0062] (1) First add 300L of water to the reaction kettle, add 5kg of alkylphenol polyoxyethylene ether into the container under stirring conditions and emulsify, then heat the emulsified mixture to 70°C, and then add 90kg of laurel Acid and stir until fully melted, then add 48kg magnesium hydroxide powder and 3.2kg zinc oxide powder to the mixed solution containing lauric acid, stir for 5 minutes and then heat preservation reaction for 40 minutes to generate milky white viscous liquid;

[0063] (2) Add 550...

Abstract

The invention belongs to the technical field of decorative materials, and particularly relates to a preparation process of scrub-resistant diatom mud for interior wall decoration. The preparation method specifically comprises: (1) screening diatomaceous earth; (2) preparing modified latex powder; (3) preparing a negative ion-photocatalyst composite solution; and (4) preparing diatom mud. Accordingto the present invention, the preparation process has characteristics of simpleness, convenient construction and environmental protection; the prepared diatom mud has advantages of high surface strength, high bonding strength and good waterproof performance; the user can clean the wall surface coated with the diatom mud according to the conventional cleaning method without the damage on the wallsurface; the wall surface coated with the diatom mud has functions of lasting sterilization, pollutant degrading and air purifying; and the diatom mud is rich in colors, and can meet a variety of construction decoration effects.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a preparation process of scrub-resistant diatom mud for interior wall decoration. Background technique [0002] Diatom mud is a natural and environmentally friendly interior wall decoration material, which is used to replace wallpaper and latex paint. It is suitable for interior wall decoration in villas, apartments, hotels, homes, and hospitals. Diatom mud is a dry powder interior wall decoration coating material prepared with diatomite as the main material. Diatomaceous earth is a single-celled aquatic plankton that lived millions of years ago, that is to say, the sediment of diatoms. After the death of diatoms, it will deposit on the bottom of the water. After hundreds of millions of years of accumulation and geological Change into diatomaceous earth. [0003] Diatoms are algae that live in oceans and lakes. Oceans and lakes are the hometown of alga...
