Embodiment 1

[0032] A formaldehyde eliminating agent comprises the following components: sodium carbonate, hydrogen peroxide, diimidazolidinone, imidazolidinyl urea, methylparaben, sodium polyacrylate and water.

[0033] The preparation steps of formaldehyde scavenger are:

[0034] (a) Dissolve 6 parts of sodium carbonate in 28 parts of water, stir for 30 minutes, then add 9 parts of hydrogen peroxide (pure hydrogen peroxide), stir for 20 minutes, and set aside;

[0035] (b) Mix 4 parts of imidazolidinyl urea and 3 parts of methylparaben, heat to 30-40°C, add 13 parts of diimidazolidinone while stirring, and cool to room temperature;

[0036] (c) Mix the solutions obtained in steps (a) and (b), then add 5 parts of sodium polyacrylate, and stir for 20-30 minutes to obtain a formaldehyde scavenger.

[0037] Dilute the formaldehyde remover obtained by the above scheme with water at a mass ratio of 1:200, and spread it evenly on 10 m 2 After 10 hours on the surface of the newly made cabinets...

Embodiment 2

[0039] Same as Example 1, the difference is that the mass parts of the components in the formaldehyde scavenger are 5 parts of sodium carbonate, 11 parts of hydrogen peroxide, 14 parts of diimidazolidinone, 3 parts of imidazolidinyl urea, and 2 parts of methylparaben , 7 parts of sodium polyacrylate and 25 parts of water, after diluting the prepared formaldehyde scavenger and water at a mass ratio of 1:250, spread it evenly on 10m 2 After 10 hours on the surface of the newly made cabinets, the formaldehyde content on the cabinets was detected by spectrophotometry, and it was concluded that 94.7% of the formaldehyde on the cabinets was eliminated after use, and at the same time, it did not affect a certain brand of water-based paint on the cabinet surface. After the formaldehyde elimination agent obtained by the above method is diluted with water at a mass ratio of 1:40, take 300g of the diluted solution and place it in an open container, and place the open container in a drawer...

Embodiment 3

[0041] Same as Example 1, the difference is that the mass parts of the components in the formaldehyde scavenger are 7 parts of sodium carbonate, 8 parts of hydrogen peroxide, 10 parts of diimidazolidinone, 5 parts of imidazolidinyl urea, and 5 parts of methylparaben , 2 parts of sodium polyacrylate and 30 parts of water, after diluting the prepared formaldehyde scavenger and water at a mass ratio of 1:230, spread it evenly on 10m 2 After 10 hours on the surface of the newly made cabinets, the formaldehyde content on the cabinets was detected by spectrophotometry, and it was concluded that 93.4% of the formaldehyde on the cabinets was eliminated after use, and it had no effect on a certain brand of water-based polyurethane paint on the cabinet surface. After the formaldehyde elimination agent obtained by the above method is diluted with water at a mass ratio of 1:45, take 300g of the diluted solution and place it in an open container, and place the open container in a drawer in ...

Abstract

The invention discloses a preparation method of a formaldehyde eliminating agent and application, and belongs to the field of preparation of cleaning bactericides. The preparation method comprises the following steps: (a) 5-7 parts of sodium carbonate are taken for dissolving in 25-30 parts of water, and are stirred by 30 min; and then, 8-11 parts of hydrogen peroxide are added to stir by 20 min for future use; (b) 3-5 parts of imidazolidinyl urea are taken for mixing with 2-5 parts of methylparaben, and are heated to a temperature of 30-40 DEG C; and 10-14 parts of diimidazolidone are added during stirring for cooling to the room temperature; and (c) the solutions obtained in the steps (a) and (b) are mixed; and then, 2-7 parts of sodium polyacrylate are added for stirring by 20-30 min to obtain the formaldehyde eliminating agent. The formaldehyde eliminating agent, prepared by the method, is free of poison and taste, is excellent in stability, and is free of secondary pollution; the formaldehyde eliminating rate can reach above 96%; and the corrosion resistance of eliminated objects is enhanced when eliminating formaldehyde.

Description

technical field [0001] The invention belongs to the field of preparation of cleaning and bactericidal agents, and in particular relates to a preparation method and application of a formaldehyde eliminating agent. Background technique [0002] Formaldehyde, also known as formaldehyde, is commonly used in wood, textile, anti-corrosion and other industries. Formaldehyde has a pungent smell and can be smelled at low concentrations. The human smell threshold for formaldehyde is usually 0.06-0.07mg / m 3 . However, there are large individual differences, and some people can reach 2.66mg / m 3 . Long-term, low-concentration exposure to formaldehyde can cause headaches, dizziness, fatigue, sensory disturbances, decreased immunity, and drowsiness, memory loss or neurasthenia, and mental depression; chronic poisoning is also very harmful to the respiratory system. Cause respiratory dysfunction and hepatotoxic lesions, manifested as liver cell damage and abnormal liver radiation energy...
