Abstract

The invention provides a formaldehyde removing agent, which consists of the following components in parts by weight: 0.4 to 2 parts of camphor leaf extract, 3 to 5 parts of ammonium hydrogen sulfate, 0.1 to 0.3 part of dicyandiamide, 0.5 to 6 parts of ethylene diamine tetraacetic acid, and 100 to 125 parts of water. According to the formaldehyde removing agent, the formaldehyde rate can be over 90 percent, and secondary pollution cannot be caused.

Description

Formaldehyde remover
Technical field
The present invention relates to a kind of formaldehyde remover, the formaldehyde remover that is particularly formed by camphortree leaf extract, hydrogen sulfate ammonia, dicyandiamide and ethylenediamine tetra-acetic acid.
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 formaldehyde remover, 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.
Formaldehyde remover of the present invention is comprised of following component by weight:
The applicant through repeatedly, deep experimental study just draws the formaldehyde remover that adopts above-mentioned prescription.This aldehydes removal rate of dispelling agent 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 formaldehyde remover may further comprise the steps:
(1) 100-110 part water, 50-60 part camphortree leaf extract and 6-9 part hydrogen sulfate ammonia are mixed, constantly stir until all components dissolves fully;
(2) continue to add 0.8-4.2 part ethylenediamine tetra-acetic acid and 2-6 part dicyandiamide, stirred 1-2 hour, get product.
