Description
Technical field
The invention belongs to purification filtering material technical field, it is related to a kind of fire-retardant filter cotton and its production technology.
Background technique
With the development of industry, air pollution is increasingly severe, and the demand about air cleaning is also increasing.Family
Air needs to purify, and vehicle interior needs air cleaning, and public place needs air cleaning, and there are also workshops to need air net
Change, the structure of air purifier most critical is exactly filter cotton, and the quality of filter cotton determines the clean-up effect of this air purifier.It crosses
The status that filter pulp just has it indispensable, because many industrial productions have to carry out in relatively clean space, such as surface
Processing, oil paint coating, spraying, precise electronic, optical electron, bio-pharmaceuticals, food production, air cooling etc., these environment need
The air to be flowed, but cannot have dust, so just needing to be fallen dust-filtering with filter cotton, only allow clean air opposite
Circulation is got up in closed space, to reach the needs of production run.
The opposite moisture resistance of filter cotton and fire protection requirement are two important performance indicators, but filtering currently on the market
Cotton flame retardant effect and moisture resistance are poor, and on the other hand, the prior art is that filter cotton is made to reach flame retardant effect, are added in the material
Halogen-containing fire retardant has certain pollution, and this fire retardant non-refractory, no there are non-biodegradable after discarding
Wash resistant and solarization, easily melting drips and the phenomenon that scald people occurs when meeting fire burning, and this kind of filter cotton is leaving fire source
Easy spontaneous combustion afterwards carrys out certain difficulty to fire guard, and production cost is also relatively high.

As further technical solution, the fire resistance fibre is Fanglun 1414 and poly- isophthalic two
The composite fibre of formyl m-phenylene diamine (MPD) fiber.
A kind of production technology of fire-retardant filter cotton, comprising the following steps:
S1, according to a kind of formula of above-mentioned fire-retardant filter cotton, it is spare to weigh each component；
S2, under the mixing speed of 1000r/min successively by polyethyleneimine, dipotassium glycyrrhizinate, polycarbonate, poly- diformazan
Radical siloxane is added in acrylate and vinyl acetate emulsion, is uniformly mixed, obtains mixed emulsion；
PEG-60 rilanit special is added in S3, the mixed emulsion obtained to step S2, adds phosphoric acid after mixing
Ester, cagelike silsesquioxane, methylisothiazolinone, ultrasonic disperse is uniform, obtains fire-retardant reinfored glue, spare；
S4,20D fire resistance fibre, 6.67D fire resistance fibre, 3.33D fire resistance fibre and 4D fire resistance fibre are mixed in opening grinding machine
It closes uniformly, obtains mixing fire resistance fibre；
Needle thorn combing after S5, the mixing fire resistance fibre shredding lapping for obtaining step S4, obtains cotton layer；
S6, the fire-retardant reinfored glue for obtaining step S3 are sprayed onto the upper and lower surface for the cotton layer that step S5 is obtained；After obtaining glue spraying
Cotton layer；
S7, it send into oven the cotton layer after glue spraying that step S6 is obtained to cooling and shaping after heating, drying, obtains fire-retardant mistake
Filter pulp.
As further technical solution, the ultrasonic disperse time is 40min in step S3.
As further technical solution, heating, drying temperature is 150~180 DEG C in step S7, and drying time is
30min。
The present invention is using principle and has the beneficial effect that
1, the moisture-proof for the fire-retardant filter cotton that production technology of the invention obtains is good, and moisture-proof reaches 100%, resistance to temperature
Height reaches as high as 300 DEG C, and good permeability, filter efficiency is high, and average filtration efficiency is up to 96.3%, and dust containing capacity is big, resistance
Small, initial resistance is smaller while reaching whole resistance 250Pa, the minimum 17Pa of initial resistance, therefore the use longevity of fire-retardant filter cotton
Order longer, the flame retardant rating of fire-retardant filter cotton meets track industry pyrotechnics poison standard, fire-retardant filter cotton adsorption ability in F1
By force, peculiar smell, carbon dioxide and other volatile organic contaminants in air can be effectively dispelled, free from extraneous odour is antimycotic, safely may be used
By property height, applicability is wide, is suitble to promote the use of.
2, it in the present invention, is mixed using 4 kinds of fire resistance fibres of different fineness, needle pierces combing, glue spraying, adds after shredding lapping
The fire-retardant filter cotton of heat drying, cooling shaping, preparation has the characteristics such as highly-breathable, lower resistance, High dust holding amount.Different fineness
Phosphate, cagelike silsesquioxane, dimethyl silicone polymer in fire resistance fibre, with formula cooperate, and significantly improve resistance
Fire the flame retardant property of filter cotton.Wherein, cagelike silsesquioxane, dimethyl silicone polymer are compounded with phosphate, make fire-retardant filtering
Cotton can quickly form a coke charge layer of charcoal protective film in burning to prevent the progress of oxidation process, the addition of siloxanes, into
One step keeps the Char Residues Structure generated fine and close and more stable, to significantly improve the flame retardant property of fire-retardant filter cotton, makes to prepare
Fire-retardant filter cotton low toxicity, low cigarette, do not melt drippage, do not cause any harm to environment, it is highly-safe.
3, in the present invention, vinegar third first is added in polyethyleneimine, dipotassium glycyrrhizinate, polycarbonate, dimethyl silicone polymer
In lotion, it is uniformly mixed, obtains mixed emulsion.Polyethyleneimine and dipotassium glycyrrhizinate cooperate, and good water solubility increases poly-
The interface compatibility of carbonic ester, dimethyl silicone polymer and acrylate and vinyl acetate emulsion adds PEG-60 rilanit special, after mixing
Phosphate, cagelike silsesquioxane, methylisothiazolinone is added, ultrasonic disperse is uniform, the fire-retardant reinfored glue each group made
Divide mixing more evenly, play synergistic function, fire-retardant reinfored glue is then sprayed onto mixing fire resistance fibre surface, fire-retardant enhancing
Glue is good with the compatibility for mixing fire resistance fibre matrix, the little particle powder in air can be sticked to fiber surface, to enhance
The filter effect of fire-retardant filter cotton, dipotassium glycyrrhizinate and methylisothiazolinone compatibility can effectively inhibit various bacteria, true
The growth of bacterium, mould enhances the bacteriostasis property of fire-retardant filter cotton, and therefore, the fire-retardant filter cotton moisture-proof of preparation is good, filtering effect
Rate is high, and dust containing capacity is big, and resistance is small, and adsorption ability is strong, and free from extraneous odour is antimycotic, practical.
4, the present invention in, the addition of polyethyleneimine, on the one hand with dipotassium glycyrrhizinate, PEG-60 rilanit special phase interaction
With improving polycarbonate, dimethyl silicone polymer, phosphate, cagelike silsesquioxane, methylisothiazolinone etc. in vinegar third
Dissolubility in lotion, make each component disperse in acrylate and vinyl acetate emulsion more evenly, auxiliary improve fire-retardant filter cotton temperature tolerance,
Anti-flammability；On the other hand, polyethyleneimine is positively charged, and dust can be made to change motion profile by electrostatic interaction and knocked fire-retardant
Filter cotton glues dust on fire-retardant filter cotton more firm, so that auxiliary enhances the filter effect of fire-retardant filter cotton.
