Problems solved by technology
[0002] At present, polypropylene tobacco tow is widely used as the main material for producing cigarette filters because of its good filterability for tar and nicotine, non-toxic and odorless, and can reduce tar content. Due to the high strength and ductility of the main body of polypropylene, the tow is difficult to cut, the mechanical wear is large, and the selective adsorption of polar substances in tar oil is poor.
In order to overcome the above disadvantages, the pure polypropylene material is usually modified to make a modified polypropylene cigarette tow to improve its comprehensive performance. The commonly used modification method is to use a polymer compound with an ethanol group during spinning Or blending and modifying inorganic fillers, or first adding components to make masterbatches, and then adding masterbatches for blending and spinning, the polypropylene material cannot be directly spun, which increases the difficulty of production control and uneven blending leads to product failure. Disadvantages such as unstable quality

Embodiment
[0016] A modified polypropylene tobacco tow special chip for producing modified tobacco tow, which is made by fully blending additives and polypropylene powder and using conventional technology. The specific production process is as follows:
[0017] 1. Select olefin-acid (ester) copolymer, polyolefin, and glyceryl monostearate as additives, according to olefin-acid (ester) copolymer: polyolefin: glyceryl monostearate: polypropylene powder Material = 0.6: 1.5: 0.1: 98 weight ratio ratio fully blended.
[0018] 2. After fully blending the additive and polypropylene powder, stir at room temperature for 15 minutes, raise the temperature to 270°C to completely melt the above blend, shape it with a screw extruder, and cool to 30°C to make modified polypropylene Special slices for tobacco tow, the melt flow rate is controlled at 30g / 10min, and the isotacticity of the finished product exceeds 97%.
[0019] The modified polypropylene tobacco tow is directly spun to produce the modifi...

Abstract
A modified polypropene chip for preparing the modified tow of cigarette is disclosed, which is prepared by proportional mixing additive with polypropene and conventional modifiying. It can be used for direct spinning to prepare said tow. Its advnatages are high modifying effect, high two quality and high productivity.
Description
technical field [0001] The invention relates to the technical field of modified polypropylene tobacco tow and its production, in particular to a modified polypropylene tobacco tow special slice and its technology for producing modified cigarette tow. Background technique [0002] At present, polypropylene tobacco tow is widely used as the main material for producing cigarette filters because of its good filterability for tar and nicotine, non-toxic and odorless, and can reduce tar content. Due to the high strength and ductility of the polypropylene main body, the tow is difficult to cut, the mechanical wear is relatively large, and the selective adsorption of polar substances in the tar oil is poor. In order to overcome the above disadvantages, the pure polypropylene material is usually modified to make a modified polypropylene cigarette tow to improve its comprehensive performance. The commonly used modification method is to use a polym...
