Problems solved by technology

[0006]3. Photocatalyst method, but the photocatalyst needs to be activated by ultraviolet light, and it has no effect at night and without visible light
In fact, photocatalysts have limited effect on removing polluting gases in the air, so developed countries rarely use them as civilian photocatalytic materials
[0007] 4. The plasma method is to generate a large amount of plasma to oxidize the formaldehyde in the air to achieve the purpose of purifying the air. This method is easy to generate ozone and cause secondary pollution to the air, and the device is complicated and consumes a lot of energy.
Although the formaldehyde-removing water-based sealing primer has good formaldehyde adsorption capacity, its bactericidal performance and corrosion resistance are poor, thereby limiting its application.

Abstract

The invention provides an anti-corrosion formaldehyde removal waterborne sealing primer which contains the following components: 20-30 parts of formaldehyde remover dispersion, 5-10 parts of bisphenol A epoxy resin and 15-20 parts of functional modifier, wherein the formaldehyde remover dispersion is a waterborne dispersion obtained by surface modification of nano-scale attapulgite / nano sepiolite powder / anion powder. According to the invention, by adding the bisphenol A epoxy resin and the functional modifier and through the systematic action between the two and the formaldehyde remover dispersion, the prepared formaldehyde removal waterborne sealing primer has strong formaldehyde adsorption ability as well as good sterilization property and corrosion resistance.

Description

technical field [0001] The invention relates to a preparation method of a water-based wood sealing primer, in particular to a corrosion-resistant formaldehyde-removing water-based sealing primer, which belongs to the technical field of water-based functional coatings. Background technique [0002] People spend most of their life living and working indoors. The environmental pollution caused by interior decoration has become a social problem, and the phenomenon of human illness, disability and death has become a social problem. The gas has a great impact on the human body and can easily lead to respiratory diseases, cancer, leukemia, and neurological diseases, especially for pregnant women, children, and the elderly. [0003] The formaldehyde in the indoor air mainly comes from the man-made panels used to make furniture, such as: medium density fiberboard, particle board, plywood, and blockboard. The adhesives used in the processing of these materials are urea-formaldehyde re...
