Description
Technical field
The invention belongs to daily-use chemical industry technical fields, and in particular to a kind of automobile-used except formaldehyde solid pharmaceutical preparation.
Background technique
China starts formally to implement " Air Quality Evaluation guide in passenger car " in March, 2012, and clear stipulaties are related
Benzene, dimethylbenzene, toluene, ethylbenzene, styrene, formaldehyde, acetaldehyde, 8 kinds of methacrylaldehyde common interior volatile organic matter concentration limit
Value successively supervises Automobile Enterprises to pay attention to product quality, reduces vehicle air pollution.
Formaldehyde is widely used, is a kind of simple production process, the public chemical products of raw material supply abundance, in chemical industry, wood
The fields such as material, weaving all generally use；But formaldehyde can generate stimulation to application on human skin mucous membrane, be greater than 0.08mg/m3Concentration
Can cause to be envious, eye is itched, throat discomfort or the adverse reactions such as pain, uncomfortable in chest, asthma, dermatitis, concentration of formaldehyde is excessively high also to be drawn
Play acute poisoning.
200 vehicles were once detected in Chinese interior decoration association air monitering center, as a result, it has been found that, if referring to Interior Space
Gas quality standard, all there is in-vehicle air formaldehyde or benzene content excessive problem in nearly 90% automobile, and most of vehicle formaldehyde is super
Mark is all at five or six times or more, and wherein the air quality of new car car is worst；External research test is even more to show: new car goes out
It is the volatilization time sustainable 6 months or more of harmful gas in vehicle concentration, interior in the meantime after factory, it can lead to passenger's body
Discomfort is also possible to cause traffic accident when serious, and therefore, the product for researching and developing a kind of formaldehyde that can effectively remove car is even more important.
Under the development of current science and technology, various purifying formaldehyde materials also occur in succession, similar with adsorbent materials such as active carbons
Based on adsorbent, using titanium dioxide and noble metal as the catalyst of representative, it is various release fragrance cover methanol peculiar smell skies
Gas freshener etc., product form is also varied, non-woven fabrics charcoal bag, air purifier, spray, coagulator etc..
Application No. is the patents of CN107185020A to disclose a kind of solid freshener for purifying in-vehicle air, main component
For aluminum sulfate, active carbon, extraction of essential oil liquid etc., gas with foreign flavor is mainly adsorbed by way of absorption and fragrant cover is different
Taste, but " volume " of program adsorbed gas is limited, it is easy to it fails, and nothing pointedly adsorbs pernicious gas, clean-up effect
It is not strong；Application No. is the patents of CN105749479A to disclose a kind of new house except formaldehyde formulations, if by spray be sprayed on furniture,
Ground, woven face can effectively absorb the harmful elements such as formaldehyde, benzene homologues on metope, have a long-term effect, but the technical solution
The form of spray clearly not applys to the car of facility compact complexity.
Summary of the invention
In view of the above problems, it is automobile-used except formaldehyde solid pharmaceutical preparation that the object of the present invention is to provide one kind, with solid system
Agent is carrier, is thoroughly eliminated the pernicious gases such as formaldehyde by chemically reacting, while having the effect of fresh air, it is easy to accomplish
And it is easy to use.
To achieve the goals above, technical scheme is as follows:
It is a kind of automobile-used except formaldehyde solid pharmaceutical preparation, in parts by weight, including following components: 0.5 ~ 5 part of gel powder, gel auxiliary agent

0.2 ~ 0.5 part of cinnamic alcohol, 0.1 ~ 0.3 part of graphene oxide solution, 0.1 ~ 0.5 part of natural essential oil, 0.1 ~ 0.5 part of sterilization antiseptic,
0.05 ~ 0.1 part of other auxiliary agents, 40 ~ 60 parts of deionized water.
Preferably, the solid pharmaceutical preparation is in parts by weight, including following components: 0.6 ~ 3 part of gel powder, gel helps
0.3 ~ 1.0 part of agent, 2 ~ 8 parts of solubilizer, 1 ~ 5 part of carboxymethyl chitosan, 0.5 ~ 1 part of cinnamaldehyde diethylacetal, 2 ~ 4 parts of glutamic acid,
0.2 ~ 0.3 part of laruyl alcohol, 0.1 ~ 0.3 part of graphene oxide solution, 0.1 ~ 0.5 part of natural essential oil, sterilization antiseptic 0.2 ~ 0.4
Part, 0.05 ~ 0.1 part of other auxiliary agents, 40 ~ 60 parts of deionized water.
Above scheme, gel powder, gel auxiliary agent, deionized water, the prepared composition that sterilization antiseptic is solid pharmaceutical preparation；Naturally
Essential oil, solubilizer are auxiliary additive, and natural essential oil is common plants essential oil such as tea tree ethereal oil, eucalyptus oil etc., and solubilizer is used
In the solubility of increase natural essential oil in water；Carboxymethyl chitosan, cinnamaldehyde diethylacetal, glutamic acid, laruyl alcohol, oxidation stone
Black alkene solution is functional additive, and there is carboxymethyl chitosan "-OH " electrophilic addition reaction elimination methanol can occur with formaldehyde,
Cinnamaldehyde diethylacetal can then occur to eliminate methanol through aldehyde condensation reaction with formaldehyde, and glutamic acid has "-NH2" can be with methanol
Affine addition reaction occurs, laruyl alcohol can promote graphene oxide when working with graphene oxide solution one well
Solution and other compositions are dissolved each other；It is obtained except formaldehyde solid pharmaceutical preparation be gel-type, can make in solid pharmaceutical preparation except formaldehyde at
Divide and continue slow release, action time is longer；The solid pharmaceutical preparation also have the function of common solid freshener fresh air and
It is easy to place, advantage easy to use.
Carried out by preferably, the gel powder be carragheen, gellan gum, agar any or two or more mixture.
Above-mentioned gel powder is preferably the mixing of one or both of carragheen and gellan gum arbitrary proportion, and carragheen is one
Kind Qinshui gelling agent, gellan gum is a kind of novel microbial exocellular polysaccharide, and both the natural hydrophilic gel in source, can answer
For in grocery trade, property to be excellent and safety coefficient is high.
Preferably, the gel auxiliary agent is any or two or more mixture of calcium lactate, sodium citrate, it is excellent
It is selected as calcium lactate.
Preferably, the solubilizer is Tween-80, rilanit special is any or two or more mixtures, it is excellent
It is selected as rilanit special.
Preferably, the sterilization antiseptic is one or more of sodium benzoate, methylisothiazolinone
