Problems solved by technology

The raw material of polypropylene is cheap, but the spinnability is poor, and it is difficult to obtain fine denier filaments. The filter tip made of it has poor overall performance and is only used in low-end cigarettes.
And can not be biodegradable, causing pollution to the environment

preparation example Construction

[0046] A method for preparing a plant polysaccharide cigarette filter, comprising the following steps:

[0047] A. Mix starch, water and plasticizer, stir at 10 or 15 or 25 or 36 or 44 or 52 or 58 or 64 or 70 or 77 or 81 or 90 or 100°C for 20 or 26 or 32 or After 38 or 44 or 52 or 58 or 66 or 74 or 80 minutes, the modified starch solution was obtained. The stirring speed is 100 or 500 or 800 or 1200 or 2000 or 3500 or 5500 or 8000 or 12000 or 16000 or 20000rpm.

[0048] B. Mixing the plant polysaccharide with the modified starch solution.

[0049] C. At a temperature of 10 or 15 or 25 or 36 or 44 or 52 or 58 or 64 or 70 or 77 or 81 or 90 or 100°C, the stirring speed is 100 or 500 or 800 or 1200 or 2000 or 3500 or 5500 or 8000 Or under the condition of 12000 or 16000 or 20000rpm, slowly add emulsifier, waterproofing agent, and adsorbent to the mixed solution of plant polysaccharide and modified starch, stir for 20 or 26 or 32 or 38 or 44 or 52 or 58 or 66 or 74 or After 80 m...

Embodiment 9

[0054] 1. 5 parts of potato starch, 100 parts of water, and 2 parts of plasticizer glycerin were stirred at 90°C for 5 minutes at a speed of 10,000 rpm, and then at a speed of 800 rpm for half an hour to obtain a modified starch solution.

[0055] 2. Mix 5 parts of konjac polysaccharide with 84 parts of modified starch solution.

[0056]3. Slowly add 3 parts of modified wood flour fiber, 2 parts of carboxymethyl cellulose, 3 parts of ethyl cellulose, and 1 part of activated carbon to the mixed solution of plant polysaccharide and modified starch at a temperature of 80 °C and a stirring speed of 2000 rpm. 1 part, 2 parts of zeolite, and then use 1000rpm speed to stir for 30min, take it out to remove air bubbles, and then pour it into a mold for molding. Cool to room temperature and put it into a cold storage for pre-freezing, then put it into a freeze dryer to dry to obtain a porous composite body, and then wrap it with pine paper after removing impurities to make a plant polys...

Abstract

The invention discloses a plant polysaccharide cigarette filter tip and a preparation method thereof. Plant polysaccharide, starch, adsorbent, plasticizer, emulsifier, waterproofing agent and plant protein are blended according to a certain proportion, so that the filter tip is prepared. The preparation method includes the following steps: (a) the starch, water and the plasticizer are blended and stirred, so that modified starch solution is obtained; (b) the plant polysaccharide and the modified starch solution are blended; (c) under certain conditions, the emulsifier, the waterproofing agent and the adsorbent are added into the mixture of the plant polysaccharide and the modified starch solution, and after stirring, the mixture is injected into a long cylindrical mold made of anti-freezing, heat-proofing material and molded; (d) the semifinished product is placed into a freezing environment and frozen, i.e. prefreezing; (e) the semifinished product in step d is placed into a freeze dryer and freeze-dried; (f) the porous composite body is taken out of the mold and deburred, and thereby a filter tip stick is obtained. Material resources are rich, the cost is low, and the three wastes cannot be produced. The performance is good, the filter tip can reduce the nicotine content by 40.2 to 84.1 percent, the tar by 26 to 72.1 percent and the nicotinamide by 20 to 39.2 percent, and after use, waste can be biodegraded.

Description

technical field [0001] The invention relates to the field of materials and environmental protection, more specifically to a plant polysaccharide cigarette filter, and also relates to a preparation method of the plant polysaccharide cigarette filter. Background technique [0002] Since the first cigarette filter using cotton as a filter material came out in 1930, the filter has become an important part of cigarette design. However, it was not until the 1950s, with the development of acetate, that filter cigarettes began to gain consumer acceptance. Cigarette filters can not only filter out some harmful components in the smoke, but also install filters on the cigarettes, which can effectively intercept the total particulate matter in the mainstream smoke of cigarettes, reduce the tar content, and reduce the impact of smoke on human health and the environment. harm. [0003] Existing cigarette filter materials are mainly divided into two classes: one is cellulose acetate fibe...
