Abstract
A form-aldehyde removing agent is proportionally prepared from water, 2-amino-2-ethyl-1-3-propanediol, Na2S2O3, Na2So3, pvA-1788, water-soluble edible essence, photocatalyst and assistant.
Description
Technical field
The present invention relates to a kind of chemical products, especially relate to the important source material that is applied to chemical industry--a kind of formaldehyde removing agent of formaldehyde.
Background technology
Formaldehyde is chemically the simplest and industrial widely used a kind of chemical substance, owing to reasons such as its reactivity are strong, cheap, become the important source material of producing urea-formaldehyde resin, terpolycyantoamino-formaldehyde resin and resol, and above-mentioned three kinds of resins in producing, wood-based plate (comprising shaving board, fiberboard and glued board) are widely used as tackiness agent.In addition, formaldehyde also is used for products such as textile auxiliary agent, papermaking, sterilization, explosive, 107 building glue, coating in a large number, and certain residual formaldehyde is mostly arranged.In addition, in the smog of vehicle exhaust, cigarette, in timber industry, timber all can decomposite a certain amount of formaldehyde when charing, saccharification, drying.These formaldehyde emission have certain irritating smell in air, and human body is caused certain injury.Therefore, controlled in burst size international, domestic equal PARA FORMALDEHYDE PRILLS(91,95).For this reason, many enterprises are arranged in recent years, but cost is mostly than higher, and effect is unsatisfactory all at exploitation formaldehyde aftertreatment products.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is to, and has proposed the formaldehyde removing agent that a kind of cost is low, effect is good.
Technical scheme of the present invention is achieved in that a kind of formaldehyde removing agent, and its material therefor is by weight composed as follows: 1000 parts in water; 2-amino-2-ethyl-1-3-propylene glycol 100-200 part; Sulfothiorine Na
2S
2O
310-25 part; Edible S-WAT Na
2SO
350-100 part; Polyvinyl alcohol 10-20 part; Water-based food flavour 1-2 part; Photocatalyst and auxiliary agent 5-50 part.
The technological operation step is:
The first step dissolving
1000 parts in water, polyvinyl alcohol (PVA1788) 10-20 part are added in the reactor, be warming up to 80-85 ℃, be incubated 1-1.5 hour, cooling.
Second step was mixed other auxiliary agent
After being cooled to 40 ℃, can add 2-amino-2-ethyl-1-3-propylene glycol 100-200 part, edible S-WAT 50-100 part, Sulfothiorine 10-25 part, water-based food flavour (orange, pineapple type) 1-2 part, photocatalyst and auxiliary agent 5-50 part, stirred 1-2 hour, and got final product discharging below 40 ℃.
Above-mentioned raw materials is all bought from Suzhou industrial chemicals supply and marketing company.
The present invention adopts the effect that is produced behind the above raw material to be:
But polyvinyl alcohol solution both aldehydes removal itself can be in the plate surface film forming, thereby plays sealing process, can be used as other de-aldehyde agent of protection again and exists, and getting both keeps secular aldehydes removal effect; 2-amino-2-ethyl-1-3-propylene glycol 100-200 part, be equipped with edible S-WAT 50-100 part, and other aldehydes removal auxiliary agent, can play best aldehydes removal effect, and can not damage the intensity of sheet material, add photocatalyst and auxiliary agent, make the existing aldehydes removal effect of this product, can decompose some other objectionable impurities again and remove.
Starting material of the present invention are colorless and odorless all, and after the mixing, effect is fine after tested, and does not produce secondary pollution.
