Problems solved by technology

The effect of plant absorption method is too slow and the effect is not obvious
The physical adsorption method (such as activated carbon adsorption) is limited by the amount of adsorption, and the validity period is short; the photocatalyst method is limited by the lack of light at night, and without light, the photocatalyst cannot function; The substance added to the paint makes the paint have the function of absorbing and decomposing formaldehyde. Its addition amount and reactivity determine the validity period and formaldehyde decomposition efficiency, but it is often prone to secondary pollution

Embodiment 1

[0019] The components of the formaldehyde-removing solution are as follows: 14% of titanium dioxide, 0.52% of sodium phosphate powder, 3.2% of calcium carbonate powder, 0.03% of xylene powder, 0.05% of brown sugar, 2.2% of metal manganese powder, and 80% of thinner.

[0020] The brown sugar was exposed to sunlight for 1 hour. Metal manganese powder is made by soaking in conventional sodium hydroxide solution for 2.5 days and then drying.

[0021] Formaldehyde-free furniture wood paint process steps: base material processing → blank processing → primer spraying → mixed topcoat spraying → post-processing;

[0022] Substrate processing: According to the door panel size and cutter type of the order, use double-sided melamine-decorated MDF in CNC milling cutter type;

[0023] Blank treatment: Use 240# sandpaper to grind the blank for the first time, spray the sealing primer after removing the flying dust, and after drying for 30 minutes, use 360# sandpaper to grind the four sides,...

Embodiment 2

[0031] The mass percentages of each raw material component of the formaldehyde-removing solution are as follows: 13% of titanium dioxide, 0.54% of sodium phosphate powder, 3.3% of calcium carbonate powder, 0.04% of xylene powder, 0.06% of brown sugar, 2.4% of metal manganese powder, and the balance is Tianna water.

[0032] The brown sugar was exposed to sunlight for 3 hours. Metal manganese powder is made by soaking in conventional sodium hydroxide solution for 2 days and then drying it.

[0033] Formaldehyde-free furniture wood paint process steps: substrate processing → blank processing → primer spraying → mixed topcoat spraying → post-processing;

[0034] Substrate processing: According to the door panel size and cutter type of the order, use double-sided melamine-decorated MDF in CNC milling cutter type;

[0035] Blank treatment: Use 240# sandpaper to grind the blank for the first time, spray the sealing primer after removing the flying dust, and after drying for 30 minut...

Embodiment 3

[0041] The components of the formaldehyde-removing solution are as follows: 15% of titanium dioxide, 0.5% of sodium phosphate powder, 3.1% of calcium carbonate powder, 0.02% of xylene powder, 0.04% of brown sugar, 2.0% of metal manganese powder, and 79.34% of thinner.

[0042] The brown sugar was exposed to sunlight for 2 hours. Metal manganese powder is made by soaking in conventional sodium hydroxide solution for 3 days and then drying.

[0043] Formaldehyde-free furniture wood paint process steps: base material processing → blank processing → primer spraying → mixed topcoat spraying → post-processing;

[0044] Substrate processing: According to the door panel size and cutter type of the order, use double-sided melamine-decorated MDF in CNC milling cutter type;

Abstract

The invention relates to a board paint process, in particular to a furniture board paint process for removal of formaldehyde and a solution for removal of the formaldehyde. The solution contains the following raw components in percentage by mass: 13 percent to 15 percent of titanium dioxide, 0.5 percent to 0.54 percent of sodium phosphate powder; 3.1 percent to 3.3 percent of calcium carbonate powder, 0.02 percent to 0.04 percent of dimethylbenzene powder, 0.04 percent to 0.06 percent of brown sugar, 2.0 percent to 2.4 percent of manganese metal powder, and 76 percent to 84 percent of thinner. The solution for removal of the formaldehyde can catalyze water and oxygen in air to have redox reaction under the condition with or without light to generate hydroxyl radical with strong oxidizing force, and the hydroxyl radical plays a role in decomposing formaldehyde, benzene, ammonia, TVOC (Total Volatile Organic Compound) and other organic compounds, so that the effects of antibiosis, mould proof, deodorization, stain repellent, hydrophile, self-cleanness and the like are simultaneously achieved.

Description

technical field [0001] The invention relates to a board paint process, in particular to a formaldehyde-removing furniture wood board paint process and a formaldehyde-removing solution. Background technique [0002] Formaldehyde is often produced during the production and processing of boards, and a large amount of formaldehyde will be produced when painting furniture made of these boards. Formaldehyde is a highly toxic substance, and it ranks second on the list of priority control of toxic chemicals in my country. Formaldehyde is defined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. Studies have shown that formaldehyde has strong carcinogenic and carcinogenic effects. The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver to health effects. Formaldehyde ...
