Abstract
The invention provides a formaldehyde decomposing agent, which consists of the following components in parts by weight: 35 to 45 parts of liquorice extract, 2.5 to 5.5 parts of oxalyl dihydrazide, 10 to 15 parts of imidazolidine, 4 to 6 parts of photocatalyst, and 100 to 110 parts of water. According to the formaldehyde decomposing agent, the formaldehyde rate can be over 90 percent, and secondary pollution can not be caused.
Description
Technical field
The present invention relates to a kind of methanal disintegrant, the methanal disintegrant that is particularly formed by licorice, oxalic acid two hydrazides, imidazolidine and photocatalyst.
Background technology
Formaldehyde is a kind of colourless poisonous gas.Formaldehyde in the house fitting-up is mainly concealed in clamping plate, lumber core, the household that high-density plate is made, timber floor etc.Because formaldehyde has stronger cohesive, also have the hardness of strengthening sheet material and insect protected, corrosion-resistant function, so be used for synthetic multiple adhesive.Gradually towards periphery environment release of formaldehyde residual or that have neither part nor lot in reaction forms airborne formaldehyde in the sheet material.The glue-line that the has solidified cracking of also can degrading under certain condition discharges formaldehyde.Temperature is higher, and burst size is larger.Formaldehyde can absorb through respiratory tract, and it damages body by causing tissue active oxygen increase, peroxidatic reaction of lipid, the immune system that affects body and large biological molecule effect etc.Formaldehyde has spread effect to skin and mucosa, and human body is had sensitization, can cause allergic dermatitis, color spot, bronchial astehma etc.It also has strong carcinogenicity and short canceration, can cause for example nasopharyngeal carcinoma and leukaemia.Along with the day by day raising of people's living standard, interior decoration is very general.The formaldehyde pollution problem has caused people's extensive concern.Sell in the market except formaldehyde property right product mostly just a kind of " surface-closed agent ", rather than truly " methanal disintegrant ".It forms the release of the temporary transient closed methanal of a skim at sheet material or furniture surface, in case this film owing to make moist or meet heat and suffer that skin cherishes, formaldehyde will come out again.Therefore, effectively remove the formaldehyde pollution that is caused by interior decoration and become problem in the urgent need to address.
Summary of the invention
The purpose of this invention is to provide a kind of methanal disintegrant, it can transform formaldehyde and be degraded into nontoxic material, effectively alleviates free formaldehyde to the pollution of room air, and can not cause secondary pollution.
Methanal disintegrant of the present invention is comprised of following component by weight:
The applicant through repeatedly, deep experimental study just draws the methanal disintegrant that adopts above-mentioned prescription.The aldehydes removal rate of this distintegrant can reach more than 90%, is higher than the like product on the market, is the crystallization that the applicant pays a large amount of painstaking effort.
The preparation method of above-mentioned methanal disintegrant may further comprise the steps:
(1) 100-110 part water, 35-45 part licorice and 2.5-5.5 part oxalic acid two hydrazides are mixed, constantly stir until all components dissolves fully;
(2) continue to add 4-6 part photocatalyst and 10-15 part imidazolidine, stirred 1-2 hour, get product.
The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail.But the invention is not restricted to given example.
Embodiment 1

(2) continue to add 4 parts of photocatalysts and 10 parts of imidazolidines, stirred 1-2 hour, get product.
Embodiment 2
The methanal disintegrant of present embodiment is comprised of following component by weight:
The preparation method of the methanal disintegrant of present embodiment may further comprise the steps:
(1) 105 parts of water, 40 parts of licorices and 3.8 parts of oxalic acid two hydrazides are mixed, constantly stir until all components dissolves fully;
(2) continue to add 5 parts of photocatalysts and 12 parts of imidazolidines, stirred 1-2 hour, get product.
Embodiment 3
The methanal disintegrant of present embodiment is comprised of following component by weight:
The preparation method of the methanal disintegrant of present embodiment may further comprise the steps:
(1) 110 parts of water, 45 parts of licorices and 4 parts of oxalic acid two hydrazides are mixed, constantly stir until all components dissolves fully;
(2) continue to add 5.1 parts of photocatalysts and 12 parts of imidazolidines, stirred 1-2 hour, get product.
The method that adopts the various embodiments described above methanal disintegrant to process sheet material, furniture or home decoration may further comprise the steps:
(1) with 1000 times of above-described embodiment Formaldehyde decomposition dilution agent;
(2) solution spraying with dilution gets final product in the surface of sheet material, furniture or home decoration.
The formaldehyde of processing sheet material, furniture or home decoration with above-described embodiment methanal disintegrant can effectively reduce formaldehyde more than 90%.
