Problems solved by technology

[0008] In the comparison document, the particle size of nano-titanium dioxide is 3-5nm, and the particle size of nano-titanium dioxide is too small, resulting in poor dispersion of nano-titanium dioxide in the dispersion medium, and even easy to agglomerate in the dispersion medium. The specific surface area of ​​the agglomerated nano-titanium dioxide changes. Small, thus affecting the purification efficiency and effect of photocatalyst on formaldehyde

Embodiment 1-3 and comparative example 1-8

[0105] Carry out following detection method to embodiment 1-3 and comparative example 1-8:

[0106] 1) Adopt 11 airtight boxes with the specifications of 1m×1m×1m, and place a tabletop board with a size of 500mm×500mm*3mm in each of them. The 11 tabletop boards are of the same type, and each one is coated with the same amount of paint. The amount of paint coating is 100ml, and the paint is water-based furniture paint produced by Qingdao Xingguo paint source manufacturer. The 11 airtight boxes were placed in the same light-proof room with constant temperature and humidity, the temperature was 25° C., and the humidity was 58%. Turn on incandescent lights in the room to ensure that each enclosure is surrounded by sufficient light. 11 desktop boards are statically placed in 11 airtight boxes for 2h, the light is turned off, and the formaldehyde content is detected by a formaldehyde content detector (Mot500), as a reference value; on 11 desktop boards, press the using method of th...

Abstract

The invention relates to a formaldehyde-removing liquid added with a biological enzyme auxiliary agent and a preparation method thereof, and relates to the technical field of air purification, which includes a photocatalyst, and the photocatalyst includes the following raw materials in parts by weight: 30-34 parts of photocatalyst, 6-10 parts of nanofiber filler, 2-6 parts of water-based acrylic polyurethane, 1-3 parts of anionic surfactant, 1-3 parts of titanate coupling agent, 6-10 parts of dispersant, 80-84 parts of deionized water ; The photocatalyst comprises the following raw materials in weight percentage: nano-titanium dioxide 10-20%, nano-zinc oxide 10-20%, aluminum sulfate 10-14%, anhydrous sodium acetate 1-5%, synergist 6-10% , and the remainder deionized water. By modifying nano-titanium dioxide and nano-zinc oxide, the dispersibility of nano-titanium dioxide and nano-zinc oxide is improved, thereby improving the purification efficiency and effect of photocatalyst on formaldehyde.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde-removing liquid added with a biological enzyme auxiliary agent and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless, pungent-smelling gas that is easily soluble in water. In the indoor environment, formaldehyde mainly comes from various boards, insulating materials and coatings. It is a carcinogenic and teratogenic substance identified by the World Health Organization, and it is also a potential strong mutagenic substance. Long-term exposure to formaldehyde gas will not only cause damage to the contact organs and respiratory system, but also cause chronic poisoning, certain damage to the reproductive system and immune system, and endanger health. Therefore, people pay more and more attention to the removal of indoor formaldehyde. The most widely used formaldehyde remover in the market is photocatalyst formaldehyde r...
