Problems solved by technology

[0003] There are already many air purifiers and air treatment additives in the market. After investigation, it is found that the relevant air purifiers currently exist have the following problems. First, the closed air purifier is only suitable for unstable urea-formaldehyde resins that volatilize harmful gases. Prevention and control play a certain role; second, the sealing agent itself contains a large amount of volatile harmful gases; third, it is partially covered by plant aromatic essential oils, and the discovery of harmful gases such as formaldehyde is shielded with low timeliness; fourth, formaldehyde captures The agent can only briefly react the harmful gas of formaldehyde emitted in the indoor environment

Embodiment 1

[0036] An anti-formaldehyde paint for wood-based panels, comprising the following components in parts by weight, a leveling agent, a penetrating agent, a hydrophobic agent, carbomer 940 resin, a curing agent, and deionized water.

[0037] The formaldehyde-resistant coating is prepared by mixing at normal temperature and pressure.

[0038] Meanwhile, the hydrophobic agent includes any one of potassium methyl silicate, sodium methyl silicate, and fluorinated polyurethane.

[0039] Furthermore, the leveling agent is polyurethane.

[0040] Moreover, the penetrating agent includes any one of sodium salt of alkyl alcohol sulfate and sodium salt of alkylsulfonic acid.

[0041] The curing agent includes any one of dipropylene glycol methyl ether and dipropylene glycol butyl ether.

[0042] When preparing, first add the leveling agent, penetrating agent, and hydrophobic agent into container A, and mix them thoroughly by stirring the raw materials, then add the resin and curing agent ...

experiment example 1

[0046]In this experimental example, the raw materials are mixed according to the following parts by weight, 5 parts of polyurethane, 5 parts of sodium alkyl alcohol sulfate or sodium alkyl sulfonate, potassium methyl silicate or sodium methyl silicate or fluorinated polyurethane 10 parts of medium, 5 parts of carbomer 940 resin, 5 parts of dipropylene glycol methyl ether or dipropylene glycol butyl ether, and 950 parts of deionized water.

Abstract

The invention discloses a method for controlling the formaldehyde release rate by controlling the moisture content of an artificial board, and relates to the technical field of building material environmental protection. The invention discloses an artificial board anti-formaldehyde coating which comprises the following components in parts by weight: 5-20 parts of a leveling agent, 10-30 parts of apenetrating agent, 25-30 parts of a hydrophobic agent, 5-100 parts of carbomer 940 resin, 5-50 parts of a curing agent and 770-950 parts of deionized water. The formaldehyde release rate is controlled by controlling the moisture content of the artificial board so that the purpose of effectively controlling harmful substances such as stable and unstable urea-formaldehyde resin in the decoration material can be achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection of building materials, in particular to a method for controlling the release rate of formaldehyde by controlling the moisture content of wood-based panels. Background technique [0002] With the development and growth of the economy, people's living standards have improved, and the living facilities at home are complete, and the quality requirements of the facilities have been improved. The air quality in the living room is also everyone's concern. In the home environment, a large number of artificial boards, wooden furniture and other decoration materials used have volatile and harmful gases released into the external environment, causing great hidden dangers to human health. For the harmful gases released by decoration materials such as artificial boards and wooden furniture, there are many treatment technologies and methods, such as the modification and upgrading of adhesives u...
