At the same time, it can match the smoking style of Chinese-style cigarettes, has little negative impact on Chinese-style cigarettes, and has a high filtration efficiency of crotonaldehyde, a harmful substance in smoke, and can improve the usability of the composite filter in Chinese-style cigarettes.

Description

A kind of binary compound filter candle that can reduce crotonaldehyde burst size in the cigarette mainstream flue gas significantly

Technical field

The utility model relates to the filter stick for the manufacture of cigarette filter, is specifically related to a kind of binary compound filter candle that can reduce crotonaldehyde burst size in the cigarette mainstream flue gas significantly.

Background technology

At present, cigarette filter mostly is single acetate fiber monobasic filter stick greatly, and the harmful substance tool that reduces in the cigarette smoke is had certain effect.Along with the growing interest of smoking and health problem, countries in the world are more and more paid attention to the exploitation of smoking material and filter structures, the purpose that some functional materials reach lowering harm and decreasing coking occurred adding in filter stick.But really being used for the filtering material of Chinese style Virginian-type cigarette seldom, is the matching problem of filtering material and Chinese style cigarette smoking style on the one hand, is the balanced problem of filtering material itself on the other hand.As active carbon, bigger to the style influence of Chinese style cigarette; Inorganic material such as diatomite, sepiolite except production of cigarettes being had many negative effects, also can make cigarette produce breath and the stimulation of some dust; Some natural organics such as tea dust, its pore structure mostly are airtight cell cavity, and are lower etc. to the filter efficiency of flue gas harmful substance.These problems have restricted the extensive use of filtering material in the Chinese style cigarette just.

The utility model content

Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of binary compound filter candle that can reduce crotonaldehyde burst size in the cigarette mainstream flue gas significantly, make its can be complementary with Chinese style cigarette smoking style, little to the negative effect of Chinese style cigarette, higher to flue gas harmful substance crotonaldehyde filter efficiency, to improve the availability of composite filter tip in the Chinese style cigarette, solve the technical problem that tobacco business needs to be resolved hurrily.

Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:

A kind of binary compound filter candle that can reduce crotonaldehyde burst size in the cigarette mainstream flue gas significantly comprises filter core and is wrapped in interior integument, outer wrapping layer on the filter core successively; Described filter core is by the acetate fiber section of interval setting and the binary composite filter element that constitutes for the compound acetate fiber section that absorbs the flue gas crotonaldehyde.

Described compound acetate fiber section is for to be provided with composite particles at acetate silk.

Described composite particles is for adopting CuSO₄The granular materials that the compound NaY molecular sieve of the shitosan of solution modified alkali lye obtains after handling.

Described compound acetate fiber section is provided with 2 ~ 5 sections.

Beneficial effect: compared with prior art, the binary compound filter candle that can reduce crotonaldehyde burst size in the cigarette mainstream flue gas significantly of the present utility model, on the basis that reduces releasing content of coke tar in cigarette, the crotonaldehyde burst size can reduce significantly, the reduction amplitude reaches more than 23%, thereby has reached the purpose of lowering harm and decreasing coking.Can be complementary with Chinese style cigarette smoking style simultaneously, little to the negative effect of Chinese style cigarette, higher to flue gas harmful substance crotonaldehyde filter efficiency, can improve the availability of composite filter tip in the Chinese style cigarette.

Description of drawings

Fig. 1 is the structural representation of binary compound filter candle.

The specific embodiment

Below in conjunction with concrete accompanying drawing the utility model is done further explanation.

As shown in Figure 1, can reduce the binary compound filter candle of crotonaldehyde burst size in the cigarette mainstream flue gas significantly, comprise filter core 1 and be wrapped ininterior integument 2,outer wrapping layer 3 on the filter core successively; Filter core 1 is the binary composite filter element, and it is compoundacetate fiber section 5 formations that theacetate fiber section 4 that arranges at interval arranged and be used for absorbing the flue gas crotonaldehyde.Compound acetate fiber section is provided with 2 ~ 5 sections, and compound acetate fiber section is for being provided with for the composite particles that absorbs the flue gas crotonaldehyde at acetate silk.

Compoundacetate fiber section 5 will be dispersed in the plasticizer triacetyl glycerine for the composite particles that absorbs the flue gas crotonaldehyde, add on the acetate silk forming to plasticizer.Wherein, composite particles is preferably and adopts CuSO₄The particle that the compound NaY molecular sieve of the shitosan of solution modified alkali lye obtains after handling.

Cigarette with acetate fiber monobasic filter stick under the identical working condition is control sample, and the binary compound filter candle that contains above-mentioned material reduces the result of crotonaldehyde burst size in the cigarette mainstream flue gas, and is as shown in table 1 below.As seen, this can reduce the binary compound filter candle of crotonaldehyde burst size in the cigarette mainstream flue gas significantly, and on the basis that reduces releasing content of coke tar in cigarette, the crotonaldehyde burst size can reduce significantly, the reduction amplitude reaches more than 23%, thereby has reached the purpose of lowering harm and decreasing coking.
