Abstract
The invention relates to a formaldehyde eliminating agent and a preparation method thereof, in particular to an eliminating agent for eliminating free formaldehyde in plate bonding agents. The formaldehyde eliminating agent comprises the following ingredients in percentage by weight: 4 to 8 percent of semicarbazide, 1 to 3 percent of xanthan gum, 5 to 7 percent of chitosan, 12 to 18 percent of stearate and the balance anion water. The ingredients are prepared into the formaldehyde eliminating agent through the steps of drying, dissolution, heating, stirring, mixing and the like. The formaldehyde eliminating agent can fast take reaction with formaldehyde, toxic and harmful byproducts and foreign materials can not be generated, in addition, the slow release effect is realized, and the effect is more durable.
Description
Technical field
The present invention relates to cleanser of a kind of noxious material and preparation method thereof, specifically, the present invention relates to a kind of remover that purifies formaldehyde and preparation method thereof.
Background technology
Phenolic resins, solid phenolic resin are yellow, transparent, amorphous block material, are blush because of containing free phenol, and proportion 1.25-1.30 is soluble in alcohol, and is water insoluble, and water, weak acid, weak caustic solution are stablized.By phenol and formaldehyde polycondensation under the catalyst condition, the resin processed through neutralization, washing.Because of selecting the difference of catalyst for use, can be divided into two types of thermosetting and thermoplasticity.
Phenolic resins has good acid resistance ability, mechanical property, heat resistance, is widely used in industries such as anticorrosion engineering, adhesive, fire proofing, grinding wheel manufacturing.In the anticorrisive agent of furniture production and adhesive material, be widely used.
Because phenolic resins is synthetic by phenol and formaldehyde polycondensation under the catalyst condition, so formaldehyde has become the major pollutants of room air.
General formaldehyde all can exceed standard in the newly-decorated house, and formaldehyde mainly contains the following aspects to health hazard:
1, spread effect: the main harm of formaldehyde shows as Mucocutaneous spread effect, and formaldehyde is the protoplasmic poison material, can occur the serious stimulation of respiratory tract and oedema, eye stimulation when sucking, have a headache with protein bound, high concentration.
2, sensitization: skin directly contacts formaldehyde can cause allergic dermatitis, color spot, necrosis, can bring out bronchial astehma when sucking high-concentration formaldehyde.
3, mutagenesis: high-concentration formaldehyde still is a kind of genotoxicity material.Animal used as test can cause rhinopharyngeal neoplasm under the situation that the laboratory high concentration sucks.
4, outstanding behaviours: headache, dizzy, weak, nauseating, vomiting, uncomfortable in chest, ophthalmodynia, have a throat-ache, that stomach is received is poor, palpitaition, have a sleepless night, lose weight, note power goes down and vegetative nervous disorder etc.; The long-term suction of pregnant woman possibly cause fetal anomaly, even dead, and the long-term suction of man can cause man's teratospermia, death etc.
The method of elimination formaldehyde commonly used mainly contains at present: ventilated; Place green plants and use active carbon.It is very limited that but active carbon and green is planted for the absorption of formaldehyde, and active carbon can reach capacity very soon, and active carbon and green to plant the speed of absorbing formaldehyde very slow.
In addition, also having a kind of method of more effectively eliminating formaldehyde is to make formaldehyde catching agent, is sprayed on indoorly, perhaps brushes on sheet material, is used to eliminate formaldehyde.
Application number is 200410037055.6, and the patent of invention that name is called " a kind of formaldehyde catching agent and preparation method thereof " discloses a kind of formaldehyde catching agent and preparation method thereof.It is that following raw materials by weight percent is evenly stirred, is mixed with and forms water: 55-75%, ammonium acetate: 4-8%, urea: 4-8%, sodium carbonate: 13-26%, sodium chloride: 0-2%, ammonium chloride: 0-3%, ammonium carbonate: 0-2%.
The defective of above-mentioned document is:
1, raw material all is that inorganic matter is formed, though can with formolite reaction, slow with formolite reaction speed, and the liquid that generates causes damage to the clothes that is placed on inside the cupboard;
2, the volatilization of formaldehyde is for up to 3-15; The formaldehyde catching agent of this invention does not possess slow-release function; Just lose effect after can only eliminating part formaldehyde, so both can make people under the situation of not knowing the agent for capturing inefficacy, suck formaldehyde gas, can when changing agent for capturing, increase cost again.
Summary of the invention
The formaldehyde catching agent reaction rate that the present invention is intended to solve in the above-mentioned document is slow, and the generation foreign matter and the fast problem that lost efficacy provide a kind of and formolite reaction speed is fast, have formaldehyde eliminating agent of slow-release function and preparation method thereof.
In order to realize the foregoing invention purpose, technical scheme of the present invention is following:
A kind of formaldehyde eliminating agent is characterized in that: comprise following components in weight percentage:
Semicarbazides 4-8%
Xanthans 1-3%
Shitosan 5-7%
Stearate 12-18%
Surplus is an anion water.
Described stearate is odium stearate, calcium stearate, dolomol, potassium stearate or aluminum stearate.
A kind of preparation method of formaldehyde eliminating agent is characterized in that: comprise following processing step:
A, the xanthans powder that takes by weighing formula ratio are put into baking oven to carry out the first time dry, and the dilute hydrochloric acid solution of putting into volumetric concentration after the drying and be 3-8% soaked 10-20 minute, take out to put into baking oven again and carry out drying second time;
B, the shitosan of formula ratio is dissolved in a part of anion water, drips the sodium hydroxide solution of mass and size specific concentration 12-25%, the pH value is transferred to 7.8-9.0, be alkalescent;
C, will dry good xanthans powder and be dissolved in a part of anion water with the stearate of formula ratio, stirring was heated 2-5 hour, left standstill 1-4 hour;
D, the semicarbazides of chitosan solution among the step B and formula ratio is added in the solution that step C makes, stirred 2-5 minute, add remaining anion water again, be cooled to room temperature after being stirred and heated to 60-80 ℃, promptly obtain this product formaldehyde eliminating agent.
The temperature dry in the first time described in the steps A is 80-95 ℃, and be 1-3 hour drying time; Dry for the second time temperature is 50-75 ℃, and be 30-50 minute drying time.
At a part of anion water described in the step B is the 10-15% of formula ratio anion water weight.
At a part of anion water described in the step C is the 30-40% of formula ratio anion water weight.
In the heating-up temperature described in the step C is 100-130 ℃.
The useful technique effect that the present invention brings:
1, formaldehyde eliminating agent provided by the invention, because solvent adopted anion water, institute is so that the raw material dissolving is more complete, and anion water itself has the effect of dust in certain elimination formaldehyde and the air, improved the detergent power of formaldehyde eliminating agent of the present invention;
2, formaldehyde eliminating agent provided by the invention, raw material adopt semicarbazides and xanthans, can be fast and free formaldehyde react elimination formaldehyde, and can not produce poisonous and hazardous accessory substance and foreign matter;
3, formaldehyde eliminating agent provided by the invention; Owing to used shitosan and stearate, they can make this formaldehyde eliminating agent external shellization, play the effect of slowly-releasing; So it is more lasting that formaldehyde eliminating agent provided by the invention is renderd a service; And shitosan is natural materials, and is nontoxic, can not endanger people's health;
4, the preparation method of formaldehyde eliminating agent provided by the invention is simple and easy to usefulness, and cost is low, is fit to large-scale production.
