Abstract
The present invention relates to a polypropylene filter rod for cigarette. It is formed from 100 portions of polypropylene tow bundle and 6-10 portions of adhesive, and the total denier of the adopted polypropylene two bundle is 3.2-3.4 ten thousand deniers, and its described adhesive is tridecyl acrylate, trihydroxymethyl propane trimethyl acrylic ester on triethylene glycol diacrylic ester. Its production method includes the following steps: spraying the getatinous adhesive monomer containing 3.0-3.5 % of alpha-hydroxy ketone on the surface of loosened tow bundle, the adhesive-spraying quantity is 6-10% of polypropylene two bundle in the weight ratio, then rolling up to obtain filter rod, radiating to make polymerization and solidification so as to obtain the invented filter rod for cigarette. It has no abnormal smell, and is easy to adhere, and is easy to implement industrial production.
Description
The present invention relates to a kind of cigarette filter stick, particularly a kind of cigarette polypropylene fiber tow filter rods and preparation method thereof.
Cigarette adopts two vinegar fiber materials usually with filter-tip material, because two vinegar fiber material feedstock derive from pine, cost an arm and a leg, complex process, and useless excellent pipe tobacco causes problems such as environmental pollution, p.22, the chemical goods magazine second phase in 1999 has been reported with polypropylene tows and has chewed material as cigarette filter, but adopt above-mentioned primary polypropylene tows to have the intensity height, the elongation at break height is difficult for cutting and bonding, and tipping speed is low, pungent peculiar smell is arranged, it is low that hardness is chewed in filter, and rod making rate hang down a series of shortcomings, and need carry out comprehensive modification to polypropylene tows and just can promote the use of.
The objective of the invention is to overcome and adopt the filter-tip raw material sources difficulty of two vinegar fibers in the prior art, easily environmental pollution, processed complex and expensive shortcoming, overcome simultaneously and adopted the intensity height that exists in the polypropylene filter, the elongation at break height, be difficult for bondingly, the shortcoming of peculiar smell arranged, and a kind of filter stick that adopts the polypropylene tows of non-solvent adhesive and hardening with radiation technology is provided.
Polypropylene filter of the present invention is made up of polypropylene tows and adhesive, 100 parts of adhesive 5-10 of its component following (weight portion) polypropylene tows part
Total dawn of described polypropylene tows is ten thousand dawn of 3.2-3.4, comprises the 10000-12000 rhizoid.
Described adhesive is the monomer polymerization type, has the vinyl monomer of two keys.Under the condition of ultraviolet light and irradiation, be opened polymerization or be cross-linked into high polymer of dual intensity, thus polypropylene tows is bonded together well.Monomer is simple function group or multi-functional acrylate, acrylic-amino ester or epoxy acrylate, as the basic ester of acrylic acid 13 (alkane), trimethylol-propane trimethacrylate or Diethylene Glycol diacrylate.The preparation method of polypropylene filter for cigarette of the present invention is as follows:
With total denier is the polypropylene cigarette tow shredding at ten thousand dawn of 3.2-3.5, to add by weight being 2-4%, the gluey binder monomer that is preferably the initator alpha-alcohol ketone of 3.0-3.3% is sprayed onto the tow surface of above-mentioned shredding, spray glue amount is the 5-10% of polypropylene tows by weight, be preferably 6-10%, be rolled into the cigarette rod, the polypropylene cigarette rod that is rolled into is at electron beam, behind X or the gamma-ray irradiation, be sprayed on the layer of adhesive monomer polymerization and the curing of polypropylene tows very thin surface, simultaneously, the tow in the filter stick is bonded together well, and irradiation dose intensity is 3-5Mev, mean current is 200-210 μ A, and exposure time is 400-700 second.
Hardness after polypropylene filter for cigarette of the present invention solidifies is 93-97%, and has elasticity, every index such as circumference and resistance to suction is all qualified, add going out excellent rate and can reaching ten thousand/ton of 170-180 of the third fibril bundle behind the glue, not only surpass the excellent rate that of 1,560,000/ton of two vinegar filter sticks, and helped realizing the smooth recovery of useless excellent pipe tobacco.See Table 1.
Table 1
| Before the modification (embodiment 4) | After the modification (embodiment 2) | The fine filter stick of two vinegar | |
| Total fiber number (ten thousand dawn) fracture strength (CN/dtex) elongation at break (%) work to break (take two vinegar as 1) goes out excellent rate (ten thousand/ton) filter tipping rates (%) tipping speed (/ minute) jealous bonding situation price (ten thousand yuan/tons) environmental pollutions (year) | 4.6-4.9 1.59-2.50 141-539 14 115 93 3000 acids can not bonding 1.5 50 | 3.9-4.0 0.55 21 0.46 170-180 (adding glue), 98 10000 free from extraneous odour non-solvent adhesive～2.0 5 | 4.4 1.0 25 1 156 98 10000 frees from extraneous odour dissolve each other type bonding～4.0 20 |
When solving the tow adhesion problem, the brute force of tow and elongation at break all descend significantly, as (intensity was 3-5Mev in 500 seconds at irradiation, mean current is 200 μ A) back tow brute force drop to 0.55CN/dtex from 1.2CN/dtex, elongation at break drops to 21% from 115.9%, these indexs all reach even are lower than the corresponding numerical value of two vinegar fibers (being respectively 1.0CN/dtex and 25%), because the reduction significantly of powerful and elongation at break, tow significantly becomes fragile, be convenient to fly-cutting, therefore can increase substantially the tipping speed (reaching 10000/minute) and the tipping rate (98%) of propene fibre filter stick.
The non-solvent adhesive of Cai Yonging has polar group in the present invention, thereby when the solution polypropylene tows is bonding, has also improved the jealous of propene fibre filter stick, and it can overcome the acid that the preceding propene fibre filter stick of modification exists when smoking.
Another remarkable advantage of the present invention is to help solving the polypropylene fibre filter stick to use the problem of environmental pollution that the back exists, because significant degraded takes place in polypropylene tows in the irradiation process, and produce a large amount of unsettled free radicals therein, therefore quicken propene fibre filter stick greatly and in atmosphere, room temperature environment, deposited degradation speed in the process.
