Description
Technical field
The present invention relates to chitin technical field, specially a kind of crust promotor composition and system with purifying formaldehyde function
Preparation Method, application method.
Background technique
Chitin (Chitin) is also known as chitosan, chitin, is rare in one kind special cellulose and nature
The positively charged alkaline polysaccharide of one kind.According to existing research achievement, the first of the 6th element of life is described as by european and American scientists
Shell element is unique positively charged tunicin of nature discovery so far, mainly has and improve immune function, nontoxic
Property auxiliary inhibit tumour function, adjust blood lipid, reduce cholesterol, improve digestive function be conducive to body-building and weight-reducing, good chelating
The savings, restraining and sterilizing bacteria, moisturizing that effect advantageously reduces internal heavy metal breathe freely, promote regeneration, prevent electrostatic, anti-spoke
It penetrates, the effect that uvioresistant etc. is brilliant.Therefore, the fabric handled through chitin is comfortably soft, and there is multifunctional health-care antibacterial to make
With
The abundant amino being rich in chitin can just show after deacetylated.Deacetylated concentration is by de- second
After acyl technique, powerful effect adsorption-decomposition function organic pernicious gas is presented in amino.
Deacetylation degree (D.D) determine amido on macromolecular chain (NH2) content number, and D.D increase, due to
Amido protonates and increases chitosan charged group in dilute acid soln, and charge density of polyelectrolyte increases, and result will
Lead to its structure, the variation in property and performance, the research in terms of chitosan dilute solution property all has ignored D.D value other side so far
The influence of journey.VANDUM et al. once had studied different ionic strength to the shadow of the chitosan molecular dimension in weak solution and viscosity
It rings.As a result think that ionic strength difference can change the dilation of random coil and then change molecular dimension and inherent viscosity, pass through
To different D.D chitosans carry out MARK-HOUWINK equation constant measurement, the results showed that K, A value with D.D value variation.To
The deacetylation of chitosan is regularly depended on by MARK-HOUWINK equation constant K, A and is changed, and in identical molecule
When amount, with the increase of deacetylation, chitosan molecular dimension in weak solution, inherent viscosity and broadening factor etc. increase, and
Characteristic with the steric hindrance factor with the increase of deacetylation than reducing.To any one chitosan in the scope of application
Sample can calculate its average molecular weight by comparing simple characteristic viscosity measuring.
Under given conditions, hydrolysis, alkylation, acylation, carboxy methylation, sulfonation, nitrification, halogen can occur for chitosan
Change, oxidation, reduction, condensation and complexing etc. chemically react, and the various chitosan derivatives with different performance are produced, to expand
The big application range of chitosan, meanwhile, its ability for removing formaldehyde is also constrained, for how to meet wanting for different application
It asks down and still keeps its original formaldehyde removal effect, need further to be studied.
Summary of the invention
The object of the present invention is to provide a kind of crust promotor composition and preparation method with purifying formaldehyde function, using side

The free radical that nano-titanium dioxide generates is effectively dispersed in carried active carbon, effectively promotes the removal efficiency of formaldehyde；Carbon nanometer
The addition of pipe forms two-dimentional Formaldehyde decomposition transmission path, further promotes Formaldehyde decomposition efficiency.
Further, the mass ratio of the chitin and the molybdenum disulfide is 5~10:1.The addition of molybdenum disulfide is
In order to promote the rigidity of composition, the structure of chitin had both been protected, has also been formed between chitin and other components and increases the effect of rubbing,
The application scenarios of composition are expanded.
Further, the mass ratio of the carbon nanotube and the glass fibre is 5~8:1.The addition of glass fibre, can
To form two-dimensional structure network on the basis of molybdenum disulfide is added, the stability of chitin structure, expansion group are further protected
Close the reference scene of object.
Further, the carried active carbon is using high temperature pyrolytic cracking (HTP), infusion process or sol-gal process preparation synthesis.
Further, the filler is powdered whiting, talcum powder and/or barium sulfate, or is calcirm-fluoride and/or electromagnetism
Stone.
A kind of preparation method of crust promotor composition, by hydroxyethyl cellulose, filler, dispersing agent, coupling agent and carbon nanometer
Pipe mixes high-speed stirred dispersion, and nanometer silicon wafer, molybdenum disulfide, emulsifier, carried active carbon, glass fibre is added and is stirred
Uniformly.
The chitin group of the 1~3% of coating quality is added in coating in a kind of application method of the crust promotor composition
Close object, high-speed stirred is uniform under conditions of 2200-2600r/min, mixing time 12-18min, using spraying, blade coating or
The mode use that person brushes.
A kind of crust promotor composition its preparation process with purifying formaldehyde function of the present invention, has following beneficial effect
