Problems solved by technology

[0005] The present invention provides a nano water-based formaldehyde-encapsulating coating and a preparation method thereof to solve the problems that the indoor formaldehyde content exceeds the standard caused by the existing indoor decoration, conventional ventilation and physical adsorption take a long time to remove, and the existing sealing coating has limited sealing effect on formaldehyde The nano water-based formaldehyde-encapsulating coating provided by the present invention has excellent tightness, adhesion, and wear resistance. It can be applied or sprayed on the surface of furniture to form a protective sealing film on the surface of the furniture paint layer. The protective sealing film can hold formaldehyde firmly. It is firmly sealed to prevent the volatilization of formaldehyde gas from furniture panels and paint layers; the preparation method has mild conditions, simple process, and is more environmentally friendly

Abstract

The invention relates to a nano water-based formaldehyde-sealing coating and a preparation method thereof. The nano water-based formaldehyde-sealing coating is prepared from the following components in percentage by weight: 2.0 to 10.0 percent of nano-crystalline cellulose, 0.5 to 3.0 percent of ultrafine micro wax powder and the balance of water-based epoxy resin, a water-based dispersing agent, a functional adjuvant, deionized water and a water-based epoxy curing agent. The nano water-based formaldehyde-sealing coating is excellent in tightness, adhesiveness and wear resistance; when the surface of furniture is coated with the nano water-based formaldehyde-sealing coating, a layer of protective sealing film can be formed on the surface of a furniture coating layer; the protective sealing film can firstly seal formaldehyde and prevent formaldehyde gas in furniture plates and coating layers from being volatilized; the preparation method is mild in condition, simple in process and more environmentally-friendly. The problems that the indoor formaldehyde content exceeds the standard content due to existing indoor decoration, time for removal of the formaldehyde via conventional ventilation and physical adsorption is long, and the sealing effect of the existing sealing coating on the formaldehyde is limited are solved.

Description

technical field [0001] The invention relates to the technical field of nano water-based coatings, in particular to a nano-water-based closed formaldehyde coating and a preparation method thereof. Background technique [0002] At present, people pay more and more attention to the problem of home decoration pollution. Indoor pollution includes benzene, toluene, formaldehyde, etc., among which the most harmful substance is formaldehyde. 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 live...
