Description
Technical field
The present invention relates to eliminating smell agent, specifically a kind of biological nano eliminating smell agent and preparation method thereof.
Background technology
At present maximum finishing pollution is exactly formaldehyde in the finishing, and formaldehyde can cause that cough, pharyngalgia, uncomfortable in chest, dizziness and nausea, myasthenia of limbs, dyspnea, the symptom such as drowsiness appear in respiratory tract and neural disease.Even more serious bring out rhinocarcinoma,, the Carciuogenesis such as laryngocarcinoma, skin carcinoma and leukemia.The cycle of general toxic gas activity is 1-10, and First Year is particularly serious, and toxic gas volatilizees soon during this, and burst size is high, thereby also more serious to the harm of human body.Room and automobile formaldehyde inside quite has harm to people's health, so, must take suitable way to reduce the content of formaldehyde
In addition, in between domestic hygiene, because sealing is tight, Air Flow is bad, and most toilet sewer pipes are without sealing device, even there is the sealing effectiveness neither be very desirable, cause abnormal flavour in the toilet, these smell components mainly are hydrogen sulfide, ammonia, sulfur dioxide etc., and these gases had both affected health, again human living environment and the life grade of impact.Eliminating smell agent majority in the middle of using is plant extract or chemosynthesis at present, the plant extract complex process, and production cost is high, and the common people are difficult for accepting; Whether whether chemosynthesis has harm to human body, and whether secondary pollution is arranged, have corrosiveness unknown.
It is reported that eliminating smell agent mainly contains following several types: physics eliminating smell agent, chemical eliminating smell agent, microbiocidal eliminating smell agent etc. at present.
The physics eliminating smell agent, the physics eliminating smell agent is to eliminate the unusual smell by physical method, utilizes the physical property of eliminating smell agent or gas with foreign flavor, does not change the result of gas component, only changes its local concentration, or perhaps relative concentration.Common are the absorption eliminating smell agent, cover eliminating smell agent etc.
The chemistry eliminating smell agent, thus chemical eliminating smell agent is to utilize oxidation, reduction decomposition, neutralization reaction, additive reaction, condensation reaction, ion-exchange reactions etc. that the smell substance that produces is become the free from extraneous odour material to eliminate abnormal flavour.
Microbiocidal eliminating smell agent, its ultimate principle are to utilize microorganism that the smell substance in the dissolved water is absorbed in microorganism in health, make a kind of process of its degraded by the metabolic activity of microorganism.Flavor is taken off in microorganism can be divided into three phases: the 1. course of dissolution of gas with foreign flavor, namely transfer to liquid phase by gas phase; 2. in the aqueous solution smell component by microorganism adsorption, absorption; 3. the smell component that enters microbial cell is that Institute of Micro-biology decomposes utilization as nutrient substance, and pollutant are removed.
Therefore, we need a kind of cost low, effective, can effectively remove finishing gas and toilet gas, biological, environmental protection, without any the eliminating smell agent of side effect.
Summary of the invention
The object of the invention is to provide a kind of biological nano eliminating smell agent and preparation method thereof.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of biological nano eliminating smell agent: eliminating smell agent is that (1-4)-2-amino-B-D glucose, ethanol and nano titanium oxide form by Chitosan, count by weight, Chitosan is (1-4)-2-amino-B-D glucose: ethanol: nano titanium oxide=3-4: 1-3: 3-4.Described nano titanium oxide particle diameter 15-50nm.
The preparation method of biological nano eliminating smell agent: being (1-4)-2-amino-B-D glucose, ethanol and nano titanium oxide with Chitosan, is that 3-4: 1-3: 3-4 mixes according to weight ratio, and then dilute with water namely obtains the biological nano eliminating smell agent.
With the eliminating smell agent of above-mentioned gained biological nano eliminating smell agent as abnormal flavour in decorating house, toilet or the car.Be that (1-4)-2-amino-B-D glucose, ethanol and nanometer titanium dioxide titanium valve mix with Chitosan, dilute according to weight ratio 1: 50-70 with clear water after mixing, and then as the eliminating smell agent of abnormal flavour in decorating house, toilet or the car.Described nano titanium oxide particle diameter 15-50nm.
The present invention has advantages of: eliminating smell agent cost of the present invention is low, effective, can effectively remove finishing gas and toilet gas, biological, environmental protection, without any side effect.And invention eliminating smell agent acid-base value is 6.5-7.5, is neutral, and wall and decoration are not produced corrosive effect.
