Description
Technical field
The present invention relates to filtering oil smoke Material Field, be specifically related to a kind of polytetrafluoroethylene fibre oil fume air filtering material and preparation method thereof.
Background technology
Along with the fast development of catering trade, adopt in food processing process explode, fry, decoct, the technique such as barbecue, thus produce a large amount of oil flue waste gas.These oil flue waste gas comprise gas, liquid, solid three-phase pollutant, and its chemical composition is extremely complicated, have strong carcinogenic, mutagenesis.These pollutants from cooking fume are just discharged into outdoor without any process, bring pollution not only to surrounding resident living environment, and destroy air quality, serious harm health.
For fume purifying, cooking fume purification handling technical method in the market mainly contains mechanical phonograph recorder separation, catalyst combustion method, absorption method, Electrostatic Treatment method etc.Wherein, absorption method has that equipment investment is few, operating cost is low, the feature of non-secondary pollution, is applied widely.But because smoke components is complicated, single sorbing material is difficult to meet purification requirement, adopts composite filter material to be conducive to removing multiple harmful components, reaches better clean-up effect, effectively alleviate the pollution of oil flue waste gas.
Summary of the invention
The object of this invention is to provide a kind of polytetrafluoroethylene fibre oil fume air filtering material, effectively can filter oil smoke, remove the harmful components in oil flue waste gas, effectively reduce oil flue waste gas and pollute.
The present invention is achieved by the following technical solutions:
A kind of polytetrafluoroethylene fibre oil fume air filtering material, it is obtained by the raw material of following weight parts:
Polypropylene fibre 20-30, polytetrafluoroethylene fibre 10-15, cotton fiber 10-15, ramee 10-15, nano-calcium carbonate 3-5, dodecyldimethylammonium hydroxide inner salt 1-2, hydroxypropul starch 0.1-0.2, oil-absorbing resin 10-20, composite modifier 10-15;
Wherein oil-absorbing resin is acrylic acid series cross-linked copolymer;
Wherein composite modifier is made up of the raw material of following weight portion: shitosan 1-2, citric acid 1-2, nano titanium oxide 2-4, water 40-60; Citric acid is first dissolved in the water by the preparation method of composite modifier, under 60-80 DEG C of condition, then adds shitosan stir until dissolve completely, add nano titanium oxide ultrasonic disperse 5-10min, to obtain final product after cooling.
A preparation method for polytetrafluoroethylene fibre oil fume air filtering material, comprises the following steps:
(1) mix after polypropylene fibre, polytetrafluoroethylene fibre, cotton fiber and ramee respectively shredding, through combing, lapping, whole boiling hot operation, obtain fiber base-material;
(2) oil-absorbing resin is mixed with nano-calcium carbonate, dodecyldimethylammonium hydroxide inner salt, obtain oil-absorbing resin mixture; Again the fiber base-material in (1) is mixed with oil-absorbing resin mixture, then in 180-220 DEG C, hot-forming under 4-8MPa condition, obtain filtering base-material;
(3) the filtration base-material surface in (2) is sprayed on after being mixed with hydroxypropul starch by composite modifier, then completely dry in 80-90 DEG C of condition, obtain polytetrafluoroethylene fibre oil fume air filtering material.
Advantage of the present invention is:
Polytetrafluoroethylene fibre has excellent chemical stability and good mechanical strength, wear-resistant, long service life.The present invention adopts polypropylene fibre, polytetrafluoroethylene fibre, cotton fiber and the multiple fibrous material compound of ramee are as carrier, combined by fibrous material and oil-absorbing resin material, filtering material is made to have good strainability to oil smoke, and by shitosan and nano titanium oxide, surface spraying modification is carried out to filtering material, poisonous in oil flue waste gas, harmful components have good absorption property, make filtering material can not only solid effectively in filter oil smoke waste gas, liquid particle, harm reduction effect can also be played, good purification, effectively can reduce the pollution of oil flue waste gas to environment, also have good high temperature resistant, decay resistance, long service life, practical.
