Abstract
The invention discloses a preparation method for a formaldehyde removal agent, comprising the following steps of: (1) mixing100-120 parts by weight of water, 45-55 parts by weight of camphor tree leaf extract and 6.5-8.5 parts by weight of ammonium bisulfate, and continuously stirring until all the constituents are completely dissolved; and (2) continuing to add1-3 parts by weight of ethylenediamine tetraacetic acid and 2.5-5.5 parts by weight of dicyandiamide, and stirring for 1-2 hours to obtain the finished product. The formaldehyde removal agent prepared by the preparation method disclosed by the invention can achieve greater than 90% of formaldehyde removal rate and cannot cause secondary pollution.
Description
Technical field
The present invention relates to a kind of preparation method of formaldehyde remover.
Background technology
Formaldehyde is a kind of colourless poisonous gas.Formaldehyde in house fitting-up is mainly concealed in clamping plate, lumber core, household, timber floor etc. that high-density plate is made.Because formaldehyde has stronger cohesive, also have and strengthen the hardness of sheet material and insect protected, corrosion-resistant function, so be used for synthesizing multiple adhesive.In sheet material, formaldehyde that is residual or that have neither part nor lot in reaction can Environment release towards periphery gradually, forms the formaldehyde in air.The glue-line that have cured cracking of also degrading under certain condition discharges formaldehyde.Temperature is higher, and burst size is larger.Formaldehyde can absorb through respiratory tract, and it makes body damage by causing tissue active oxygen increase, peroxidatic reaction of lipid, the immune system affecting body and large biological molecule effect etc.Formaldehyde has spread effect to skin and mucosa, has sensitization to human body, can cause allergic dermatitis, color spot, bronchial astehma etc.It also has strong carcinogenicity and short canceration, can cause such as nasopharyngeal carcinoma and leukaemia.Along with the raising day by day of people's living standard, interior decoration is very general.Formaldehyde pollution problem has caused the extensive concern of people.The formaldehyde property right product that remove sold in the market are mostly a kind of " surface-closed agent ", instead of " methanal disintegrant " truly.It forms at sheet material or furniture surface the release that a skim carrys out temporary closure formaldehyde, once this film is owing to making moist or heat and suffer that skin is cherished, formaldehyde will come out again.Therefore, effectively remove the formaldehyde pollution caused by interior decoration and become problem in the urgent need to address.
Summary of the invention
The object of this invention is to provide a kind of preparation method of formaldehyde remover, formaldehyde conversion can be degraded into nontoxic material by obtained remover, effectively alleviates the pollution of free formaldehyde to room air, and can not cause secondary pollution.
Formaldehyde remover of the present invention is made up of following component by weight:
The applicant through repeatedly, deep experimental study just draws the formaldehyde remover adopting above-mentioned formula.The aldehydes removal rate of this remover can reach more than 90%, higher than the like product on market, is the crystallization that the applicant pays a large amount of painstaking effort.
The preparation method of above-mentioned formaldehyde remover, comprises the following steps:
(1) by weight 100-120 part water, 45-55 part camphor leaf extract and 6.5-8.5 part ammonium hydrogen sulfate are mixed, constantly stir until all components dissolves completely;
(2) continue to add 1-3 part ethylenediamine tetra-acetic acid and 2.5-5.5 part dicyandiamide by weight, stir 1-2 hour, get product.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.But the invention is not restricted to given example.
