The invention provides formaldehyde absorbent which is prepared from, by weight, 40-60 parts of melamine, 5-15 parts of a moisturizing agent, 0.3-2 parts of a wetting agent, 1-5 parts of a dispersing agent, 0-1 part of a PH conditioning agent, 0.3-2 parts of an anti-settling agent, 0.1-0.5 part of a deforming agent and 25-50 parts of deionized water. The invention further provides a preparation method of the formaldehyde absorbent. According to the formaldehyde absorbent, the melamine and the absorbed formaldehyde react to generate melamine resin, a product is good in stability, formaldehyde is not released any more, and thus the purpose of completely absorbing the formaldehyde is achieved; besides, the raw material source is wide, the preparation method is simple, the process is easy to control, repeatability is high, and the formaldehyde absorbent and the preparing method thereof can be applied and popularized on a large scale; the formaldehyde absorbent can be used independently and can also be used in cooperation with traditional formaldehyde absorbent.
Description
Technical field
The invention belongs to Material Field, specifically relate to a kind of formaldehyde absorbent and preparation method thereof.
Background technology
Because the functions such as formaldehyde has stronger adhesion, have the sheet material hardness of reinforcement and insect protected, anticorrosion, so the use of formaldehydeScope is very extensive, and all kinds of wood-based plates while being typically used as interior decoration are as glued board, core-board, medium density fiberThe artificial board such as plate or particieboard, the adhesive of producing at present wood-based plate use is the urea aldehyde tree taking formaldehyde as main componentFat. According to experimental verification, in all pollutants, formaldehyde ranks the first, and is a kind of height suspect carcinogen, due toThe scope of application of artificial board in household is very extensive, so the phenomenon of formaldehyde is very common, is exactly to contain first in additionThe adhesive of aldehyde composition or wall finiss coating etc., as latex, foamed glue, plastics, paint, coating, wallpaper etc., bondingAgent is used to aspect wooden engineering and metope brushing processing in interior decoration, and especially the formaldehyde in the latex of metope is difficult toRemove, and the volatilization cycle of formaldehyde is very long, therefore have healthy livable environment in order to ensure people, reduces indoor formaldehyde aobviousObtain particularly important.
Have in the market very eurypalynous formaldehyde adsorbent, as porous sorbing materials such as active carbon, silicon bath mud, they can be inhaledAttached formaldehyde, simultaneously also can adsorb other airborne material, after absorption reaches capacity, just can not absorb, therefore not againCan keep long-term efficacy.
Melamine, is commonly called as melamine, extract of protein, and white monoclinic crystal, almost tasteless, be slightly soluble in water, preparation is very easy to,Cheaply be easy to get. In prior art, also utilize melamine solution to eliminate formaldehyde, but formula in active ingredient lower, withThe compatibility of other resin is poor.
