Embodiment 1

[0040] A formaldehyde-removing coating with dual functions of adsorption and decomposition, which is composed of the following components in weight percentage: 28% heavy calcium, 13% emulsion, 8% calcined kaolin, 7% washed kaolin, 7% titanium dioxide, sepiolite / Nano-TiO 2 Composite material 6%, dispersant 0.4%, wetting agent 0.3%, defoamer 0.3%, multifunctional additive 0.3%, antifungal agent 0.3%, film forming aid 0.3%, antifreeze agent 0.4%, bactericide 0.3% %, thickener 0.4%, water 28%. Its preparation method is as follows:

[0041] Sepiolite / Nano TiO 2 Preparation of composite materials:

[0042] A. Add 5g of sepiolite to a 250ml three-necked bottle, slowly add 100ml of ethanol, 12.5ml of tetrabutyl titanate, stir at a speed of 400r / min for 30min in a constant temperature water bath at 25°C, and then ultrasonically disperse for 30min to make the sepiolite and The solution is mixed evenly;

[0043] B. Heat up to 90°C and stir the solution at a speed of 500r / min until ...

Embodiment 2

[0051] A formaldehyde-removing coating with dual functions of adsorption and decomposition, which is composed of the following components in weight percentage: 27% heavy calcium, 14% emulsion, 7% calcined kaolin, 8% washed kaolin, 8% titanium dioxide, sepiolite / Nano-TiO 2 Composite material 5%, dispersant 0.3%, wetting agent 0.4%, defoamer 0.2%, multifunctional additive 0.3%, antifungal agent 0.4%, film forming aid 0.5%, antifreeze agent 0.2%, bactericide 0.4 %, thickener 0.3%, water 28%. The difference between its preparation method and Example 1 is that sepiolite / nano TiO 2 Composite materials are prepared differently, while coatings are prepared in the same way.

[0052] The sepiolite / nanometer TiO of the present embodiment 2 The preparation method of the composite material is as follows:

[0053] A. Add 8g of sepiolite to a 250ml three-necked bottle, slowly add 130ml of ethanol, 20ml of tetrabutyl titanate, stir at a speed of 600r / min in a constant temperature water b...

Abstract

The invention discloses a formaldehyde eliminating coating with dual functions of adsorption and decomposition, which solves the problem that the existing coatings release harmful substances such as formaldehyde into air and have no function in eliminating formaldehyde. The formaldehyde eliminating coating comprises the following components by weight percent: 25-30% of coarse whiting, 10-15% of emulsion, 4-10% of calcined kaolin, 4-10% of washed kaolin, 4-10% of titanium dioxide, 4-10% of sepiolite or nanometer TiO2 composite material, 0.1-0.6% of dispersing agent, 0.1-0.6% of wetting agent, 0.1-0.6% of antifoaming agent, 0.1-0.6% of multifunctional assistant, 0.1-0.6% of mildew preventive, 0.1-0.6% of coalescing agent, 0.1-0.6% of antifreezing agent, 0.1-0.6% of bactericide, 0.1-0.6% of thickener, and 25-30% of water. The invention also provides a preparation method of the coating. The coating has very strong function in eliminating formaldehyde, and is safe and reliable.

Description

technical field [0001] The invention specifically relates to a formaldehyde-removing coating with dual functions of adsorption and decomposition and a preparation method thereof. Background technique [0002] Formaldehyde is a volatile organic compound, colorless, with a special smell, slightly heavier than air, and easily soluble in water. Formaldehyde has an important impact on human health and has a strong irritating effect on the eyes, respiratory tract, human mucous membranes and skin; acute poisoning can cause symptoms such as tearing, runny nose, coughing, and various respiratory diseases; chronic inhalation of low concentrations can cause persistent headaches , weakness, insomnia, etc.; long-term skin contact can cause dermatitis, which will have adverse effects on the human respiratory system, digestive system and central nervous system, resulting in abnormal lung and liver immune function. Formaldehyde is so harmful to the human body that the production of buildi...
