Abstract
The invention provides a novel formaldehyde scavenging agent which has high formaldehyde scavenging efficiency, durable action effect and simple production process, and can effectively scavenge formaldehyde from indoor air and simultaneously reduce the formaldehyde release amount of the decoration materials. The formaldehyde scavenging agent is characterized in that: the product is prepared from the following raw materials according to a weight ratio: 2-60% of formaldehyde scavenging factor, 1-10% of film forming agent, 1-10% of film forming aid and 40-80% of water. The formaldehyde scavenging agent is aqueous, can be sprayed to indoor air, wall or furniture, has high formaldehyde capturing rate and is convenient for use.
Description
Technical field
The present invention relates to a kind of preparation of removing harmful organic substance and preparation method thereof, particularly a kind of formaldehyde scavenger and preparation method thereof.
Background technology
Formaldehyde is a kind of important chemical material, is widely used in organic synthesis.With in the synthetic compound of formaldehyde with closely-related adhesive, coating and the textile auxiliary of mainly containing of people's daily life, like amino resins, the polyvinyl formal of rustproof lacquer and textile finish etc. in being used to produce.The production technology of these products is simple, cost is low; Therefore be used for the post processing of Wood Processing production such as particieboard, glued board, fiberboard and textile in a large number, in the application process of production, processing and the final products of these products, all can have a certain amount of formaldehyde to discharge.At present, formaldehyde has become China's room air primary pollutant.Research shows, low concentration formaldehyde can make the people produce symptoms such as headache, dizzy, upper respiratory tract stimulation, eye stimulation, allergic dermatitis, and the formaldehyde of higher concentration also has teratogenesis, carcinogenesis, therefore, administers indoor formaldehyde and pollutes very urgent.
At present, people remove the method that formaldehyde in indoor air pollutes has much the wherein topmost formaldehyde scavenger that is to use.Current more existing formaldehyde scavengers occur, but the ubiquitous problem of formaldehyde scavenger that occurs at present is: 1, some formaldehyde scavenger and formolite reaction are slower, and elimination efficiency is lower, DeGrain; 2, some formaldehyde scavenger is short action time, and the sensitiveness of PARA FORMALDEHYDE PRILLS(91,95) is not high, for the formaldehyde removing poor effect of trace; 3, some formaldehyde scavenger manufacturing equipment and complex process, production cost is high; 4, some formaldehyde scavenger poorly water-soluble is inappropriate for a large amount of uses.
Summary of the invention
The objective of the invention is to technical problem to above-mentioned existence; Provide that a kind of PARA FORMALDEHYDE PRILLS(91,95) elimination efficiency is high, action effect is lasting and the simple novel methylene oxide scavenging agent of production technology; Can remove the formaldehyde in the room air effectively, reduce the burst size of formaldehyde in the ornament materials simultaneously.
In order to realize the foregoing invention purpose, the present invention adopts following experimental program.
Proportioning raw materials of the present invention (percentage by weight) is formed:
The formaldehyde removing factor: 2-60%; Film forming agent: 1-10%; Coalescents: 1-10%; Water: 40%-80%.
Be preferably following percentage by weight especially:
The formaldehyde removing factor: 10-50%; Film forming agent: 2-5%; Coalescents: 2-8%; Water: 50-70%.
Particularly the formaldehyde removing factor is carbamide compounds such as ethylene-urea, urea, amino acidses such as glycine, threonine, and in the ammonium salt such as ammonium chloride, ammonium sulfate one or more.
Particularly film forming agent is a Ludox.
Particularly coalescents is a polyvinyl alcohol.
The advantage of product of the present invention is:
1, the present invention adopts catching property of height formaldehyde to eliminate the factor.Wherein ammonium chloride and formolite reaction generate hexamethylenetetramine; Glycine is easy to generate N, N one dihydroxymethyl glycine with formolite reaction as the formaldehyde volatilization inhibitor; Ethylene-urea has urea groups and alkyl simultaneously, is again five-membered ring structure, therefore have preferably with the activity of formolite reaction with stable preferably.Catch factor while interaction energy for these three kinds and eliminate sheet material, furniture and airborne formaldehyde rapidly, effectively.
2, product of the present invention is a water aqua type, and is easy to use, can directly be sprayed in the air or is painted on the inwall and the back side of various artificial boards surface and furniture.
3, product price of the present invention is cheap, and production equipment and production technology are very simple, and therefore, production cost is lower.
4, product safety environmental protection of the present invention, raw materials used all nontoxic, and do not produce secondary pollution.
5, the film forming agent and the coalescents of product use of the present invention can form one deck dense film, and this tunic can be enclosed in the inside with the formaldehyde removing factor and formaldehyde, plays the effect that continues to purify formaldehyde.
