The method includes the following steps that acrylamide and a first part of acrylic acid are dissolved in deionized water, a first reagent is prepared under catalysis of sodium bicarbonate powder, then the first reagent, remaining acrylic acid and 2-hydroxyethylamine react, and the carbon dioxide absorbing agent for the vehicle is prepared. The method is simple and easy to implement, and the prepared absorbing agent can effectively absorb carbon dioxide, is free of toxin and harmless and does not corrode other objects in the environment.
Description
Technical field
The present invention relates to the technical field of carbon-dioxide absorbent.
Background technology
Human body is unsuitable for hanging up one's hat in the more airtight space that gas concentration lwevel is higher, and as stayed in for a long time in the bad automobile of gas permeability, space carbon dioxide concentration constantly rises, and human body is not easily discovered, and easily causes serious physical impairment.
Common carbon-dioxide absorbent mostly is the inorganic matter of alkalescence, and its corrosivity is comparatively strong, is unsuitable for using at automotive interior.
Summary of the invention
The object of the invention is to propose that a kind of carbon dioxide absorption ability is comparatively strong, nonhazardous, environment produced to the preparation method of organic carbon-dioxide absorbent of corrosiveness, the present invention is achieved through the following technical solutions above-mentioned purpose:
A preparation method for automobile-used carbon-dioxide absorbent, comprises the following steps:
1) acrylamide and Part I acrylic acid are dissolved in deionized water, add sodium bicarbonate powder wherein, mixed solution is obtained after stirring, by this mixed solution in the water-bath of 60 ~ 80 DEG C, hot reflux 1 ~ 2h is added under nitrogen atmosphere, thereafter be cooled to normal temperature and carry out suction filtration, obtaining the first reagent;
2) the first reagent is added in remaining acrylic acid and 2 hydroxy ethylamine, and add oxolane, the second mixed solution is obtained after stirring, by this mixed solution in the water-bath of 30 ~ 40 DEG C, hot reflux 12 ~ 24h is added under nitrogen atmosphere, thereafter be cooled to normal temperature and carry out suction filtration, it is dry that the pressed powder obtained by suction filtration carries out washing, namely obtains described carbon-dioxide absorbent.
The carbon-dioxide absorbent that the present invention prepares can absorbing carbon dioxide effectively, nontoxic, to the corrosion-free effect of other article.
Preferably: calculate by mass parts, described absorbent is synthesized by following component: 5 ~ 10 parts of acrylamides, 25 ~ 35 parts of acrylic acid, 16 ~ 19 parts of 2 hydroxy ethylamines.
In addition preferably: calculate by mass parts, described absorbent is synthesized by following component: 8 parts of acrylamides, 26 parts of acrylic acid, 17 parts of 2 hydroxy ethylamines.
In addition preferably: described acrylamide and the acrylic acid mass ratio of Part I are 1:2.
The present invention is simple to operate, and preparation efficiency is high, and the carbon-dioxide absorbent prepared can absorbing carbon dioxide effectively, nontoxic, to the corrosion-free effect of other article.
