Description
Technical field
The present invention relates to a kind of composite filter tip and cigarette thereof.
Background technology
Smoking has two harm greatly, the one, healthhazard; The 2nd, to the harm of environment.Smoking has directly the harm of environment, also has indirectly, concludes and to get up to have three types, and one type is to throw out the influence of stub to environment without care; One type is that the stub that does not extinguish constitutes disaster hidden-trouble; Another kind of is that the manufacturing process of filter-tip material can discharge pollutants in a large number because of the material consumption forest reserves of making cigarette filter.Thus it is clear that, all direct or indirect relevant of the two big harm that smoking causes with cigarette filter.The harm that reduction smoking causes at first should be done from improving the material of making cigarette filter.
The material of present domestic making cigarette filter is mainly cellulose diacetate and polypropylene; Nearly 300,000 tons of total amount; Wherein the consumption of cellulose diacetate has accounted for more than 80%; Because excellent performance mainly is used in the medium-to-high grade cigarette, yet the core technology of manufacturing Celluloseacetate cigarette filter tow is all by the control of large enterprises of external a few family, the main dependence on import of Celluloseacetate cigarette filter tow product and correlation technique; Chinese import Celluloseacetate cigarette filter tow had surpassed 100,000 tons in 2010, accounted for more than 40% of total flow.Domestic fabrication portion also is holding by offshore company's technology.
Celluloseacetate cigarette filter tow is to be raw material with the natural wood pulp, makes acetylizing agent with aceticanhydride, and acetic acid is made solvent; Under catalyst action; Wood pulp cellulose is carried out acetylation, and through preliminary treatment, acetify, hydrolysis, precipitating, washing, extruding, drying, cellulose obtains modification; Become the cellulose diacetate sheet (secondary cellulose acetate sheets) that dissolves in acetone and other organic solvent and tool spinnability; Secondary cellulose acetate sheets through dissolving, filtration, spinning, curl, production technology processing such as drying obtains Celluloseacetate cigarette filter tow, is a kind of secondary filter material, is mainly used in the making cigaratte filter.
The Celluloseacetate cigarette filter tow that is used for cigarette filter has following advantage:
1) tow is easy to be bonded into filter stick, and adhesive is a triacetyl glycerine; 2) the filter stick combination property of processing is excellent relatively in current material.
But there is following obvious deficiency simultaneously in Celluloseacetate cigarette filter tow:
1) derives from timber (growth cycle is generally greater than 5 years); Diacetate fiber is the goods and materials that the cellulose in the timber prepares through acetylation; A large amount of diacetate fibers that use not only increase the consumption degree to the forest reserves, also can cause environmental pollution by lot of consumption COD (COD); 2) although the cellulose diacetate degradable, degradation cycle usually surpasses 4 years, so abandoning of filter stick can be caused certain environmental pollution; 3) Celluloseacetate cigarette filter tow very easily burns, and disaster hidden-trouble is arranged; 4) adopt the solution spinning spinning, complex manufacturing has environmental issues such as solvent acetone volatilization recovery; 5) the equal dependence on import of the production technology of domestic Celluloseacetate cigarette filter tow and equipment is because technical monopoly impels the tow price higher; 6) Celluloseacetate cigarette filter tow is as the cigarette holder filtering material, and its filtering feature to flue gas is not desirable especially.
The flue gas of cigarette is a kind of aerosol, and Celluloseacetate cigarette filter tow does not have direct interception function to aerosol.It is just according to aerocolloidal dynamics, is deposited by aerosol particles and fiber generation mechanical collision and holds back flue gas.Because the acetate fiber chemical affinity is relatively poor, there is not the effect of harmful substance in the selectivity interception flue gas basically.But because the uniqueness of selecting,, remain at present and can't substitute fully even if Celluloseacetate cigarette filter tow has all shortcoming.
PLA is a kind of novel high polymer biomaterial that is formed by lactic acid polymerizes, has good human body compatibility, and degradable has certain flame-retarding characteristic.Find that in test cigarette tipping acid fiber by polylactic filter tip has tangible interception function to the carbonyl complex in the flue gas (like formaldehyde, crotonaldehyde or the like), the benzo pyrrole in the flue gas, nitrosamine is also had more obviously tackle function.
The Heat stability is good of PLA, processing temperature 170-230 ℃, good solvent resistance is arranged, available multiple mode is processed.Like extruding, spinning, biaxial stretch-formed and injection-blow molding.Outside the product decapacitation biodegradation of processing by PLA; Biocompatibility, glossiness, the transparency, feel and good heat resistance; Also have certain antibiotic property, anti-flammability and ultraviolet-resistent property; Therefore purposes very extensively can be used as packaging material, fiber and non-woven fabric etc., is mainly used in fields such as clothes (underwear, coat), industry (building, agricultural, forestry, papermaking) and health care at present.U.S. Nature-Works company is the PLA manufacturer that the whole world is maximum, technology is the most ripe, produces 140000 tons of PLAs per year.The technology that China makes PLA starts to walk early to produce per year about 5 kilotons, is only second to the U.S..Single with the PLA volume analysis, the application of PLA still is in the starting stage.
PLA is failed to obtain wide popularization and application and is especially failed to be applied at cigarette industry, and be the technological deficiency that several keys are arranged because of it: 1) the vitreum temperature of PLA is lower, generally about 60 degree Celsius; 2) hydrophily is relatively poor, and regain is low; 3) resilience, flexibility are lower etc.
The patent of invention of making cigarette filter tip rod with the acid fiber by polylactic tow is existing a lot, but this type patent of having announced does not all reach real commercial use value, its main cause have following some:
1, the relative diacetate fiber of the fillibility of acid fiber by polylactic tow is poor, does not reach diacetate fiber filter tip specification requirement instructions for use with the hardness of the cigarette filter tip rod of its making, influences the presentation quality and the sense organ requirement of cigarette.Its filter rod hardness is generally than diacetate fiber filter rod low about 15%.And cigarette to filter tip hardness number franchise between ± 3%.
2, it is big to suck resistance.Promptly under the situation that acid fiber by polylactic filter rod hardness and diacetate fiber filter tip hardness number are more or less the same, the resistance of sucking of acid fiber by polylactic filter rod but is higher than the diacetate fiber filter rod.Generally want high by about 15%, have a strong impact on the smoking property of cigarette impression.
3, technical indicator is attended to one thing and lose sight of another.Stress the hardness number accordance, resistance to suction significantly improves; The accordance of paying attention to the resistance to suction index can cause that then filter tip hardness significantly reduces.The technological matching problem that causes filter-tip filter efficiency and quality to be difficult to be in harmonious proportion.
4, the density of polylactic acid slice is cut into slices less than two acetic acid, and generally speaking, acid fiber by polylactic is made filter-tip yield should be higher than diacetate fiber.But because the elasticity of acid fiber by polylactic is weaker than diacetate fiber, so both input-output ratios have certain deviation.About about 5% (this is the filter-tip experiment situation of acid fiber by polylactic of not using plasticizer) greatly
5, the plasticizer that is not fit to acid fiber by polylactic.The plasticizer related patent U.S. Patent No. of the acid fiber by polylactic of having announced at present all belongs to bonding agent basically, does not have basically
IncreaseMould effect.And the so-called acid fiber by polylactic plasticizer of this type all has tangible adhesive, can have a strong impact on filter rod former running efficiency during use, generally can reduce device efficiency about 70%.Cause bigger technical indicator fluctuation simultaneously.And contaminated equipment, to consume the plenty of time cleaning equipment after having produced.
6, owing to PLA vitreum temperature low (though through various modifications), the filter rod and the filter tip of tipping on cigarette that roll with the acid fiber by polylactic tow all the drop-head phenomenon can occur, have a strong impact on the cigarette presentation quality.
The practical problem that these expose in application test has seriously hindered acid fiber by polylactic tow applying at cigarette industry.
