A kind of modified glass-fiber dedusting material
Technical field
The invention belongs to environmental technology field, and in particular to a kind of modified glass-fiber dedusting material.
Background technology
PM2.5 refers to particulate matter of the diameter less than or equal to 2.5 microns, also referred to as lung particulate matter in air.Because of grain
Footpath is small, and rich in substantial amounts of poisonous and harmful substances, thus the influence to health and atmosphere quality is bigger.PM2.5 is represented
The content of this particle in per cubic metres of air, this value is higher, and it is more serious just to represent air pollution.In addition, industrial part
Application, sheet material coating etc. manufacturing process in, can also produce has containing meta-acid or meta-alkali, molecule, bad smell
Evil waste gas, these waste gas are sometimes unprocessed to be also emitted into air.
Glass fibre is because high-strength, corrosion-resistant, high temperature resistant, smooth hydrophobic, dimensionally stable are indeformable, at dip coating
Its wearability is improved again after reason, therefore is a kind of preferable filtering material.It is compared with linen-cotton, more resistant to high temperature and corrosion-resistant;With
Chemical fibre is compared, and intensity is higher and size is more stable.Especially high temperature resistant, it is missing of ignition, do not burn, even more natural fiber,
Chemical fibre is incomparable, and therefore, glass fiber filter material is the conventional material of filter bag in sack cleaner.But glass
There is also the defects of the trapping effect to fine dust is poor, toughness is inadequate, and service life is short for fiber.In view of drawbacks described above, application
People combines Shandong grain and oil company and develops new modified glass fibre dedusting material.
The content of the invention
The defects of in order to overcome prior art glass fibre sorbing material, the invention provides a kind of modified glass-fiber to remove
Dirt material, material absorption dust removal performance is good, and filter efficiency is high, service life length.
The object of the present invention is achieved like this:
A kind of modified glass-fiber dedusting material, it is prepared according to following technique:Step 1)Broken and grinding, step
2)Cationic starch is modified, step 3)Stirring and heating, step 4)Mix, step 5)Stirring, spray and dry;
Specifically, it is prepared according to following technique:
Step 1)Broken and grinding:Zeolite and sepiolite are added in disintegrating machine successively and crushed, then with swelling
Soil mixing, then be ground, it is 200 mesh powders, as compound 1 to obtain particle diameter;The zeolite, sepiolite and bentonite
Mass ratio be 2:2:1;
Step 2)Cationic starch is modified:Add deionized water into cationic starch, be uniformly mixing to obtain suspension, then
Add step 1)1,500 turns/min of gained compound stirs 10min, then stands 6 hours, and precipitation is collected by filtration, precipitation is placed in
50 DEG C of drying, finally crush and obtain compound 2;Wherein, the mass ratio of cationic starch, deionized water and compound 1 is 1-
2:15-25:3-5;
Step 3)Stirring and heating:By nano diatomite, methacryloxypropyl trimethoxy silane and its go
Ionized water is added sequentially in agitator tank, is heated while stirring, it is to be heated to 90 DEG C when, maintain 90 DEG C continue stir 30min;So
After be cooled to 60 DEG C, add bamboo charcoal powder, stir 30min, obtain compound 3;Wherein, nano diatomite, methacryloxy
The mass ratio of propyl trimethoxy silicane, deionized water and bamboo charcoal powder is 2:1:10:3;
Step 4)Mix:By titanate coupling agent titanate coupling agent and acrylic acid according to 2:1 mass ratio is well mixed
Obtain compound 4;
Step 5)Stirring, spray and dry:Compound 2 and compound 3 are added in compound 4, stirred
To mixed liquor, then by mixed liquor even application to glass fibre, 30min is stood, then in 90 DEG C of dry 10min, finally
Room temperature is naturally cooled to, is produced;Wherein, the compound 2, compound 3 and the mass ratio of compound 4 are 3-5:4-7:5-9.
Preferably,
The particle diameter of the bamboo charcoal powder is 100-200um.The particle diameter of the nanometer silicon carbide and nano diatomite is 50-
100nm。
The titanate coupling agent is isopropyl three(Dioctylphyrophosphoric acid acyloxy)Titanate coupling agent.
The beneficial effect that the present invention obtains mainly includes:
The present invention to glass fibre by being modified so that rough surface is hard, specific surface area is big, improves pliability
It is good with mechanical strength, adsorbing powder dust strainability, moreover it is possible to adsorb the pernicious gases such as ammonia nitrogen and oxysulfide;Acrylic acid is dilution
Agent and adhesive, metatitanic acid fat is auxiliary flame retardant, while plays a part of coupling agent, dispersant, can not only improve anti-flammability
Can, and the binding strength of each raw material can be increased;Bamboo charcoal powder contains substantial amounts of micropore, has strong adsorption function, it is entered
Modification is gone, has greatly increased the contact area of it and other materials, heavy metal, pernicious gas etc. also have good absorption to make
With;The present invention carries out surface modifying and decorating by adding cationic starch to zeolite, sepiolite and bentonite so that powder band
There is electric charge, improve adsorption capacity, additionally it is possible to so that product has certain electrostatic adsorption.
