Embodiment 1

[0042] A coating capable of absorbing and decomposing dual-function formaldehyde removal. The coating is composed of the following components in weight percentage: 29% heavy calcium, 11% emulsion, 7% calcined kaolin, 8% washed kaolin, 6% titanium dioxide, and modified sea foam Stone / Nano TiO 2 Composite material 7%, dispersant 0.3%, wetting agent 0.4%, defoamer 0.2%, multifunctional additive 0.3%, antifungal agent 0.4%, film forming aid 0.4%, antifreeze agent 0.3%, bactericide 0.3 %, thickener 0.4%, water 29%. Its preparation method is as follows:

[0043] Modified sepiolite / nano-TiO 2 Preparation of composite materials:

[0044] 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;

[0045] B. Add 0.1gGd 2 o 3 Dissolve in 1.5ml d...

Embodiment 2

[0055] A coating capable of absorbing and decomposing dual-function formaldehyde removal. The coating is composed of the following components in weight percentage: 27% heavy calcium, 12% emulsion, 9% calcined kaolin, 7% washed kaolin, 7% titanium dioxide, and modified sea foam Stone / Nano TiO 2 Composite material 7%, dispersant 0.4%, wetting agent 0.3%, defoamer 0.3%, multifunctional additive 0.2%, antifungal agent 0.3%, film forming aid 0.3%, antifreeze agent 0.5%, bactericide 0.2 %, thickener 0.5%, water 28%. Its preparation method differs from Example 1 in that modified sepiolite / nano TiO 2 Composite materials are prepared differently, while coatings are prepared in the same way.

[0056] This example modified sepiolite / nano-TiO 2 Preparation of composite materials:

[0057] 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 bath at 40°C for 22min, an...

Abstract

The invention discloses a formaldehyde-removing coating with an absorption function and a decomposition function. The coating solves the problems that an existing coating gives off harmful matter such as formaldehyde to the air and does not have a formaldehyde-removing function. The coating comprises, by weight, 25-30% of ground calcium carbonate, 10-15% of emulsion, 4-10% of calcined kaolin, 4-10% of washed kaolin, 4-10% of titanium dioxide, 4-10% of modified sepiolite and nano TiO2 composite materials, 0.1-0.6% of dispersant, 0.1-0.6% of wetting agent, 0.1-0.6% of defoamer, 0.1-0.6% of multifunctional promoter, 0.1-0.6% of mildew preventive, 0.1-0.6% of coalescing agent, 0.1-0.6% of anti-freezing agent, 0.1-0.6% of fungicide, 0.1-0.6% of thickener and 25-30% of water. The invention further provides a preparation method of the coating. The coating has strong formaldehyde-removing performance, and is safe and reliable.

Description

technical field [0001] The invention specifically relates to a formaldehyde-removing coating capable of absorbing and decomposing dual functions 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 buildin...
