Description
Technical field
The present invention relates to one kind containing the in-car air cleaning materials of PVA and its preparation technology, belong to in-car air cleaning dress
Put technical field.
Background technology
With continuing to develop for China's economy, automobile has been the indispensable vehicles of people's daily life.With city
Air pollution on the increase year by year of city private car owning amount, road is increasingly serious, and interior space is narrow and small, air stream
The general character is poor, is unfavorable for the diffusion of pollutant, and very big harm is carried out to the health care belt of car owner.How in-car air quality is improved, into
The topic paid close attention to for numerous car owners.
Activated carbon is also known as activated carbon black, is black powder or bulk, graininess, cellular amorphous carbon, also there is row
The regular crystal carbon of row.Activated carbon, due to being irregular alignment, there is pore in structure between interconnection, the meeting in activation
Carbon tissue defects are produced, therefore it is a kind of porous carbon, bulk density is low, and specific surface area is big.The specific surface area of normal activated carbon
In 500~1700m2Between/g.It is a kind of purposes extremely wide industrial adsorbents with very strong physical absorption performance, can be effectively
Colourity, stink are removed, most organic pollutants and some inorganic matters is can remove, includes some poisonous heavy metal substances.
Polyvinyl alcohol is important industrial chemicals, for manufacturing Pioloform, polyvinyl acetal, resistance to gasoline pipeline and vinylon synthesis
Fiber, is widely used as fabric-treating agent, emulsifying agent, paper coating, adhesive, glue etc..
Antibacterial peptide former, which refers to the class produced in insect bodies through induction, has the basic polypeptide material of antibacterial activity, its molecule
Amount is made up of 2000~7000 or so many amino acid residues.This kind of active peptides majority has strong basicity, heat endurance
And the features such as broad-spectrum antiseptic, mainly gram positive bacteria is worked, it has been widely used in the fields such as medical treatment and food fresh keeping.
Air conditioner filter used in existing market most vehicles on sale is for PM0.3 just as void
If, even the air conditioner filter of some High Tier Brands is also barely satisfactory through actually detected filter efficiency.Due to activated carbon
Filtering adsorbing material not only crosses the effect of small pollution particle in air filtering with preferable, and can also play the work eliminated the unusual smell
With, it is the relatively good air conditioner filter element material of effect, therefore typically now in-car air conditioner filter element all contains activated carbon composition, still
The filter core of activated carbon composition, which can be substituted, almost not to be had but, and this just restricts the development of air conditioner filter element industry, also, with to pollution
Research increasingly become more meticulous, activated carbon filtering adsorbing material be badly in need of realize more preferably filter effect come cause user acquisition it is more easypro
Suitable environment inside car and then reduction nose, lung disease, while can preferably protect in-car air-conditioning system again.
Chinese patent：Authorization Notice No. is CN104888530A, and publication date is public for the patent of invention on September 9th, 2015
A kind of activated carbon air conditioner filter element material and preparation method thereof is opened, it is characterised in that be made up of the raw material of following parts by weight：Sludge
100 ~ 150, maize straw 13 ~ 17, peanut shell 15 ~ 24, zinc chloride 30 ~ 50, magnesium silicate 13 ~ 16, oxidation mistake 6 ~ 9, cetyl
Smelling of trimethyl hinge 2 ~ 4, polyvinyl alcohol 2 ~ 3, fluorination mistake 6 ~ 8, hydrotalcite 8 ~ 12, sepiolite powder 5 ~ 6, distillation appropriate amount of water；This hair
The zirconium fluoride of bright addition；Hydrotalcite and sepiolite greatly improve the bactericidal properties, heat endurance, ion exchange of active sludge carbon
Performance, improves adsorption capacity and adsorption range, improves the use scope of adsorbent, and acticarbon of the invention prepares work
Skill is simple, and extensively, cost is low, excellent performance, good as air conditioner filter element materials'use effect for raw material sources, and replacing number of times is few, makes
Use long lifespan.
Chinese patent：Authorization Notice No. is CN103845956A, and publication date is public for the patent of invention on June 11st, 2015
Opened a kind of activated carbon fiber air conditioner filter element and its preparation technology, be made with viscose rayon based activated carbon, be first with concentration be 1 ~
10% non-toxic polyethylene alcohol adhesive is then hung 10 ~ 20 minutes in being soaked 2 ~ 10 minutes under normal temperature at a temperature of 20 ~ 60 DEG C；
Then impregnated 3 ~ 10 minutes using 1 ~ 10% aqueous polyurethane adhesive, then 50 ~ 100 points of the drying at a temperature of 120 ~ 180 DEG C
The specific surface area that clock is solidify to form is the composite felt or cloth of 700 ~ 1200 meters squared per grams.The present invention can keep PARA FORMALDEHYDE PRILLS(91,95), benzene class
Material very high adsorptivity, while being difficult tear, without hair loss phenomenon.
The content of the invention
It is an object of the invention to provide one kind containing the in-car air cleaning materials of PVA and its preparation technology, it is ensureing car
Stop dust and fine particulates in extraneous pollution air in the case of being circulated with outside air into the car, so as to have
Effect filters the pollutants such as PM2.5, toluene, formaldehyde into the car, while strengthening the effect of antibacterial and mouldproof.
The technical proposal of the invention is realized in this way：One kind contains the in-car air cleaning materials of PVA and its preparation technology,
The raw material of the activated carbon filtering adsorbing material include activated carbon granule, non-woven fabrics, antiseptic, binding agent and polypropylene air filter
Cloth, it is characterised in that its preparation method, specific preparation process is as follows：Binding agent is PVA polyvinyl alcohol, and activated carbon granule is bamboo
Adulterate biological antibiosis agent between charcoal, its layer of charcoal, and biological antibiosis agent is wool sulphur antibacterial peptide；Activated carbon granule is with resisting in purification material
Microbial inoculum accounts for the 1 ~ 2% of gross mass, and binding agent accounts for the 1 ~ 10% of gross mass, and remaining is activated carbon granule, antiseptic and binding agent mixing
Afterwards, add water, with activated carbon granule, antiseptic and binding agent intermixture, water quality ratio 98 ~ 88：1~2：1~10：500 mixing, are stirred
Mix and uniformly obtain mixed liquor, stirring requires the dynamic viscosity for control mixed liquor in more than 100cP, then by obtained mixed liquor
Uniform applicator roll is pressed in nonwoven surface, 1 ~ 2 millimeter of coating thickness, after the non-woven fabrics after coating is put into oven for drying 3 hours
Take out, active carbon nonwoven fabric is made in 80 DEG C of oven temperature；Obtained active carbon nonwoven fabric and polypropylene air filter cloth are passed through again
Heat seal process is combined, that is, in-car air cleaning activated carbon filtering adsorbing material is made.
Described activated carbon granule can be replaced with coconut husk charcoal or straw charcoal by bamboo charcoal.
The positive effect of the present invention be its gas permeability for not only improving activated carbon filtering adsorbing material, absorption property and
Anti-microbial property, while activated carbon can be made to solidify to form good adsorption layer well in nonwoven surface.
