Embodiment 1

[0020] Take coniferous wood pulp boards with a fiber length of 1.0-2.5mm, after crushing, single fiberization, and screening, after opening evenly, the mass of 70% of the dry paper weight is air-flow transported to the web forming machine to form a web under negative pressure, and Finish the mesh surface with a hot roller and control its thickness at 1.2mm; after pre-pressing, use a total of 13% polyacrylate glue for sizing, firstly sizing the front side, and then sizing the acetate fiber Mixed with triacetin and glycerol triacetate evenly, and the addition amount of the two (accounting for dry paper weight) is 15% and 2% respectively, and applied to the front of the fiber web through the spray roller, then rolled, and passed through the first oven for 100 ℃ drying; use the same method to sizing, spraying, and rolling on the reverse side of the fiber web; then it is dried in the second oven at 100 °C, and then enters the next oven at 150 °C for curing and puffing, and then it i...

Embodiment 2

[0022] Repeat Example 1 with the following differences:

[0023] Regenerated cellulose fiber bamboo fiber with a fiber length of 3.0-4.0mm and wood pulp board with a fiber length of 1.0-2.5mm, the ratio is 20%:80%, accounting for 80% of the dry paper weight; with a total of 14% polyacrylate copolymer The material glue is used for sizing, and the cellulose triacetate and triacetin triacetate with a particle size of 80-100 mesh are mixed uniformly at 5% and 1% (accounting for dry paper weight) respectively, and applied to the fiber web through a spray roller.

[0024] After testing, the physical indicators of the obtained dry-laid paper, including quantitative, tightness, and longitudinal tensile strength, all meet the requirements of the filter rod forming machine. The filter rod of the filter material is prepared through the filter rod forming experiment, and the physical properties of the filter rod meet the requirements of the industry through the comprehensive test bench te...

Embodiment 3

[0026] Repeat Example 1, with the following differences:

[0027] Regenerated cellulose fiber soybean protein fiber and synthetic fiber polypropylene fiber with a fiber length of 3.0-4.0 mm, wood pulp board with a fiber length of 1.0-2.5 mm, the ratio is 10%: 10%: 80%, accounting for 55% of the dry paper weight; Use polyvinyl acetate emulsion with a total amount of 5% for sizing, and mix cellulose diacetate and acetyl triethyl citrate (accounting for dry paper weight) at 30% and 10% (accounting for dry paper weight) and evenly , applied to the fiber web by a spray roll.

[0028] After testing, the physical indicators of the obtained dry-laid paper, including quantitative, tightness, and longitudinal tensile strength, all meet the requirements of the filter rod forming machine. The filter rod of the filter material is prepared through the filter rod forming experiment, and the physical properties of the filter rod meet the requirements of the industry through the comprehensive...

Abstract

The invention discloses a paper filter material capable of effectively reducing phenol content in cigarette smoke and a processing method thereof. The paper filter material is formed by processing 40%-80% of base fiber, 5%-30% of acetified pulp, 0.5%-10% of carrier and 5%-15% of adhesive in a dry process. The method comprises the steps of fiber processing, single fibrillation, screening, air laying, adhesive material application, roll-in molding, drying and the like. The paper filter material obtained by adding the powdery acetified pulp can effectively reduce tar and phenols substance in the cigarette smoke, and particularly reduce the content of phenol which is one of seven harmful constituents, and the harms on smokers are reduced. The hardness of a molded filter stick can be enhanced by the acetified pulp and the carrier thereof, the problem of collapse existing in the prior art is reduced, and particle matter, the phenols substance and the tar in the cigarette smoke can be effectively reduced. The preparation process of the processing method is simple, acetate fiber is replaced by the acetified pulp, the production cost is effectively reduced, and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, further belongs to the technical field of cigarette filter material processing, and in particular relates to a paper filter material which can effectively reduce the amount of phenol in cigarette smoke and a processing method thereof. Background technique [0002] As an important cigarette material, the filter rod is an important means used in the development of cigarette product harm reduction and tar reduction technology. At present, the widely used cellulose diacetate tow filter rod has better filtration efficiency for particulate phase components and harmful components in smoke, but with the continuous improvement of the cigarette industry’s requirements for harm reduction and coke reduction, acetate fiber filter rods are becoming more and more popular. The more unable to meet the requirements. Therefore, paper filter rods are gaining more and more attention and attention from the...
