Problems solved by technology

New furniture is generally better sealed, and it is difficult for the coating to penetrate into the interior of the furniture. If it penetrates into the interior of the furniture, moisture and moisture-retaining materials will absorb water and cause deformation of the furniture.
In addition, amino acid formaldehyde scavenger is applied to remove formaldehyde because there is only a thin layer and the duration is short, there will be crystallization, poor adhesion and easy to fall off, it is not convenient for long-term use, and it can only remove formaldehyde, and cannot absorb and reduce other indoor pollutants concentration

Embodiment 1

[0030] A kind of diatom mud coating that adds amino acid to remove formaldehyde, each component and quality are:

[0031] Compound amino acid diatomite 35kg, sepiolite 20kg, bentonite 5kg, attapulgite 5kg, cellulose ether 0.8kg, starch ether 6kg, quartz sand 20kg

[0032] The preparation method of compound amino acid diatomite is:

[0033] 1. Heat 1kg of water to 50°C and keep it warm

[0034] 2. Take 390g glycine and stir it into hot water to dissolve

[0035] 3. After stirring and dissolving, add 39g of sodium carbonate and continue stirring to dissolve, then add 0.1g of alkaline protease (from Taian Xindeli Bioengineering Co., Ltd.), keep it at 50°C for 3 hours, and then take the calcined first-grade silicon Alginate is added to the solution and the solution is sucked up

[0036] 4. Dry the diatomite inhaled with glycine or put it in an oven for drying. The oven temperature is 100-200°C, which is lower than the melting point of glycine at 248°C to avoid its decomposition...

Abstract

The invention relates to a diatom ooze coating with amino acid added and formaldehyde removed. The diatom ooze coating is prepared from amino acid or compound amino acid kieselguhr and specifically prepared from, by mass, 26-65% of compound amino acid diatomite, 0-40% of kieselguhr, 18-25% of sepiolite, 0-15% of bentonite, 0-15% of attapulgite, 0-1.8% of tourmaline, 0.7-1.1% of cellulose ether, 5-8% of starch ether and 0-20% of quartz sand. The diatom ooze coating is simple in formula, can ensure adhesion strength, is free of powder falling for a long time and long in service life, and ensures the practicability of diatom ooze carriers. In addition, pore blockage is reduced, adsorption is ensured to the maximum extent, and indoor pollutant gas is effectively adsorbed; after amino acid ingredients are added, formaldehyde adsorbed into a wall and amino acid molecules dispersed in pores of diatom ooze minerals can react on a quite large superficial area, and formaldehyde can be more sufficiently removed.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a diatom mud coating, in particular to a diatom mud coating which adds amino acid to remove formaldehyde. Background technique [0002] The main indoor pollutant is formaldehyde, and the long-term volatilization of formaldehyde will affect the air quality. At present, most diatom mud coating products commonly seen on the market use nano-titanium dioxide to remove formaldehyde. After production, construction and occupancy, nano-materials can enter the air and enter the human body to cause potential harm to the human body. Moreover, some diatom mud has a complex formula, and the bonding force is not durable. If powder enters the indoor air, or is bonded with latex powder, it will block the pores of diatom earth to a certain extent, and affect the adsorption and humidity control performance of diatom mud. [0003] CN102633475A provides a non-glue diatom mud building material, the components i...
