Embodiment 1

[0061]Weigh 50 kg of homopolybutylene succinate (PBS) with a weight average molecular weight of (15±1) million and a dispersion index of 1.7, and dry it in an oven at 65°C for 2 hours. Weigh 49 kg of homopolylactic acid with a weight average molecular weight of (15±1) million and a dispersion index of 1.5, and dry it in an oven at 55°C for 5 hours. After the two raw materials are dried, all join in the high-speed mixer, and add 0.5 kilogram of triphenyl phosphate and 0.5 kilogram of antioxidant 1222 (3,5-di-tert-butyl-4-hydroxyphenyl diethyl phosphate) in the mixer , stir evenly at high speed.

[0062] The mixed material after stirring is extruded and granulated on a Φ57 twin-screw extruder with an aspect ratio of 32. The temperature of the screw barrel is set at 190°C for the first stage, 200°C for the second stage, and 200°C for the third stage. The fourth stage is 200°C, and the fifth stage is 195°C. The extruded material strips are pelletized by a pelletizer, dried on-li...

Embodiment 2

[0070] Taking by weighing 30 kilograms of weight-average molecular weight is (10 ± 1) ten thousand, and dispersion index is 1.2, and the copolymer polybutylene succinate (polybutylene succinate ( PBS) and dried in an oven at 60°C for 3 hours. Take by weighing 68 kilograms of weight-average molecular weight and be (10 ± 1) ten thousand, dispersion index is 1.2, the copolymerized polylactic acid that contains the ethylene glycol monomethyl ether chain link of 1% (chain number) random distribution on the molecular chain, at 45 ℃ Dry in the oven for 8 hours. After drying, add the two kinds of resin raw materials into a high-speed mixer, and add 1 kg of long-chain phosphorus-sulfur compound H-MOD and 1 kg of triphenyl phosphite into the mixer, and stir evenly at a high speed. The above mixture is extruded and granulated on a Φ65 twin-screw extruder with an aspect ratio of 28. The temperature of the screw barrel is set at 195°C for the first stage, 205°C for the second stage, 215°C...

Embodiment 3

[0079] Take by weighing 70 kilograms of weight-average molecular weight to be 350,000, and the dispersion index is 3.0, and the copolymer polybutylene succinate (PBS) that contains 30% (number of chain members) randomly distributed hexanediol links on the molecular chain is at 75 ℃ Dry in the oven for 3 hours. Take by weighing 30 kilograms of weight-average molecular weight and be 300,000, the dispersion index is 3.0, the copolymerized polylactic acid that contains the ε-caprolactone chain link of 30% (chain number) random distribution on the molecular chain, dry in 50 ℃ of ovens for 8 Hour. Add the dried two resin materials into a high-speed mixer and stir evenly, extrude and granulate on a Φ65 twin-screw extruder with an aspect ratio of 28, set the temperature of the first stage of the screw barrel to 215°C, and It is 220°C, the third stage is 230°C, the fourth stage is 220°C, and the fifth stage is 215°C. The extruded material strips are pelletized by a pelletizer, dried ...

Abstract

The invention provides a biodegradable cigarette fiber material and a cigarette filter. The biodegradable cigarette fiber material comprises the following raw materials of 1-99wt percent of poly(butylene succinate) polymer, 1-99wt percent of polylactic acid polymer and 0-3wt percent of stabilizing agent, and the cigarette fiber material is prepared by processing the raw materials with a melting spinning process. The poly(butylene succinate) polymer and the polylactic acid polymer can be respective homopolymers of the two polymers per se and can also be copolymers containing other monomer materials, which do not exceed 30 percent of the total quantity of respective molecular chain segments of the two polymers. The invention also provides a biodegradable cigarette filter rod prepared from the cigarette fibre material through sizing processing, and a cigarette product. The provided cigarette filter has a property equivalent to the property of the traditional general cigarette filter, a cigarette end discarded by a smoker can be decomposed within shorter time in the natural environment, and the pollution of the cigarette waste to the environment is avoided at present while the requirement of cigarette production is met.

Description

technical field [0001] The invention relates to a fiber material for cigarettes and a cigarette filter made of the fiber material. The fiber material for cigarettes and the cigarette filter are made of polybutylene succinate (PBS) polymer and polylactic acid polymer The alloy material composed is base resin, which has excellent biodegradability. Background technique [0002] Cigarette filters have the functions of filtering, blocking and absorbing harmful components such as nicotine and tar in smoke. In addition to the above functions, good filter materials should also be able to improve the taste of smoke, reduce the stimulation of smoke on the oral cavity and the human body. Health damage. As a relatively mature technology, the materials currently used to manufacture cigarette filters are generally made of cellulose acetate fiber and polypropylene fiber. Considering the processing performance and the comprehensive performance of the final filter tip, cellulose acetate fib...
