Embodiment 1

[0052] Homopolybutylene succinate (PBS) with a weight-average molecular weight of 15±10,000 and a dispersion index of 1.7 was selected as the base resin. According to PBS: triphenyl phosphite: epoxidized soybean oil: amino resin, it was 97 : Weigh the material in a weight ratio of 0.5:1.5:1, dry it in an oven at about 65°C for 2 hours, stir it evenly in a high-speed mixer, and extrude it on a Φ57 twin-screw extruder with an aspect ratio of 32. The barrel temperature is set to 120°C for the first stage, 140°C for the second stage, 150°C for the third stage, 150°C for the fourth stage, and 145°C for the fifth stage. The extruded strip is cut into pellets by a pelletizer, dried with hot air online, and packaged to obtain the special material for cigarette holder sticks of the present invention.

[0053] The above-mentioned special material for cigarette holder is spun on a Φ65 melt spinning machine with a screw length-diameter ratio of 28. The temperature of the first section of ...

Embodiment 2

[0060] The weight-average molecular weight is (10±1) ten thousand, the dispersion index is 1.2, and the molecular chain contains 18% (number of chain segments) randomly distributed terephthalic acid-linked copolymerized polybutylene succinate (PBS) As the base resin, the material was weighed in a ratio of 94: 1: 5 according to the weight ratio of copolymerized PBS: trimethyl phosphate: long-chain phosphorus-sulfur compound H-MOD, dried in a 60 ℃ oven for 3 hours, Mix evenly in a high-speed mixer, extrude and granulate on a Φ65 twin-screw extruder with a length-to-diameter ratio of 28, and set the screw barrel temperature to 125°C for the first stage, 145°C for the second stage, and 155°C for the third stage. , the fourth segment is 155°C, and the fifth segment is 145°C. The extruded strip is cut into pellets by a pelletizer, dried with hot air online, and packaged to obtain the special material for cigarette holder sticks of the present invention.

[0061] The above-mentioned...

Embodiment 3

[0068] It is 350,000 to choose the weight average molecular weight, and the dispersion index is 3.0, and the copolymerized polybutylene succinate (PBS) that contains 30% (number of chain members) randomly distributed hexanediol links on its molecular chain is base resin It is the substrate resin. After drying in an oven at 60°C for 3 hours, it is spun on a Φ65 melt spinning machine with a screw length-to-diameter ratio of 28. The screw temperature of the spinning machine is set to 130°C for the first stage, and 130°C for the second stage. The second stage is 145°C, the third stage is 155°C, the filter temperature is 155°C, the box temperature is 155°C, and the straight pipe temperature is 155°C. After being sprayed out from a spinneret with a specification of 1050×3, it is cooled by side blowing of dry air with a temperature range of 20 to 40°C.

[0069] The tow after above-mentioned cooling is coated with oil agent in the oiling tank, and the oiling agent in the oiling tank i...

Abstract

The invention provides a biodegradable cigarette fiber material and a cigarette filter tip. The biodegradable cigarette fiber material comprises the following components: 90-100% of poly (butanediol succinate) polymer and 0-10% of stabilizing agent, wherein the poly (butanediol succinate) polymer is a high molecular polymer of which the chain link of butanediol succinate in the molecular chain accounts for no less than 70% of the total chain link, the weight-average molecular weight is from fifty thousand to three hundred and fifty thousand, and the dispersancy index being 1.2-3.0. The cigarette fiber material is prepared by performing the melting spinning process on the raw materials. The invention further comprises a biodegradable cigarette filter tip rod prepared by shaping the biodegradable cigarette fiber material and cigarette products. The properties of the cigarette filter tip provided by the invention are equivalent to the properties of the universally used cigarette filter tip in the current market. The butt discarded by a smoker can be decomposed in a short time in natural environment. The cigarette production is met while the problem that the traditional discarded butt pollutes the environment is solved.

Description

technical field [0001] The invention relates to a cigarette fiber material and a cigarette filter made by using the fiber material. The cigarette fiber material and the cigarette filter use polybutylene succinate (PBS) polymer as the base resin, and have 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 improve the taste of smoke, reduce the stimulation of smoke to the oral cavity and the impact on human body. health damage. As a relatively mature technology, the materials currently used to manufacture cigarette filters are generally cellulose acetate fibers and polypropylene fibers as raw materials. Considering the processing performance and the comprehensive performance of the final production filter, cellulose acetate fibers are the first choice. Cellulose acetate fib...
