Description

High air permeability forming paper for cigarette filter rods

technical field

The utility model relates to a high air permeability forming paper, in particular to a high air permeability forming paper for cigarette filter rods.

Background technique

As we all know, cigarette filter rod paper is composed of a core material such as cellulose acetate and an outer covering paper material. The paper material has a two-layer structure. Paper, the outer layer is the tipping paper used when the filter rod is combined with the cigarette. In order to reduce the harm of smoking to the human body, the tobacco industry is now carrying out a coke reduction project. One of the measures used for coke reduction is to carry out laser drilling on tipping paper. The forming paper adopts high air permeability forming paper, so that when smoking cigarettes, the air enters the mainstream smoke through the fine pores of the tipping paper and the high air permeability forming paper, which plays a role in diluting the smoke and reducing tar. But its shortcoming of existing forming paper is:

(1) Low air permeability;

(2) The glue penetration problem is serious.

Owing to there is above-mentioned shortcoming in molding paper, the production of cigarette filter tip stick can't be normally carried out.

Utility model content

The purpose of the utility model is to provide a forming paper with high air permeability, which is high in air permeability, light and thin, and high in tensile strength.

In order to achieve the above object, the technical solution provided by the utility model is: a high-permeability forming paper for cigarette filter rods. When the filter is formed, the covering paper covering the core material of the filter has two layers, and the outer layer is tipping paper. , the inner layer is a high air permeability forming paper, and the two are glued tightly with hot melt adhesive and then firmly connected to the filter core body of the cigarette.

The air permeability of the inner high air permeability forming paper is 3000-20000CU. The tensile strength of the high air permeability forming paper of the inner layer is between 1.6-2.0/g.cm ⁻³ .

The thickness of the high air permeability molding paper in the inner layer is 0.6-0.4mm.

The high air permeability forming paper contains chemical wood pulps such as softwood kraft pulp, softwood kraft pulp, hardwood kraft pulp, hardwood kraft pulp and polymer compounds.

Detailed ways

As mentioned above, making filter stick paper for cigarettes with high air permeability forming paper has a great effect on reducing coke in the tobacco industry. Paper is a loose and porous material, and the air permeability of paper is determined by various factors in the papermaking process. For example, wood pulp raw material, light or heavy beating degree, large or small pressing pressure, etc. Practice has proved that: using 100% chemical wood pulp as raw material, using a cylinder paper machine and applying polymer compound treatment, can produce High air permeability forming paper for cigarettes with an air permeability of 3,000-20,000 CU, no glue penetration during molding, strength performance that meets the requirements of use, and fibers that are evenly dispersed.

The fiber raw material used in the utility model—chemical pulp has many types, such as coniferous wood sulphite pulp, coniferous wood sulphite pulp, broadleaf wood sulphite pulp, broadleaf wood sulphite pulp, etc., which can be used in the manufacture of forming paper A single fiber raw material or more than two kinds of fiber raw materials can be used. The cylinder paper machine used can be an ordinary cylinder paper machine or a specially modified cylinder paper machine; the polymer compound used can be high Molecular synthetic resin can also be polymeric carbohydrates. Dilute fiber raw materials—various chemical pulps with water by a hydraulic pulper, beat until uniform with a beater, add an appropriate amount of polymeric synthetic resin, and use a rotary screen to make paper Machine wet papermaking can be done. The molding paper 2 and the tipping paper 1 are tightly glued with hot melt, wrapped around the filter tip material 3 made of cellulose acetate, etc., and fixed on the cigarette body 4 .

Description of drawings

Accompanying drawing 1 is the utility model longitudinal sectional structural drawing

Accompanying drawing 2 is the schematic diagram that is made into cigarette with the utility model

Wherein 1 is the outer layer tipping paper, 2 is the inner layer high air permeability forming paper, 3 is the filter tip core, and 4 is the cigarette.

Example 1

After disintegrating 100% coniferous bleached kraft pulp with water in a hydraulic pulper, dilute it to 3%, beat it to 15°SR with a beater, mix it with a 2% aqueous solution of dispersant, and wet it with a cylinder paper machine. It can be made into high air permeability forming paper for cigarette paper with a basis weight of 25g/m ² and a thickness of 0.66mm.

Example 2

Mix softwood kraft pulp and broadwood kraft pulp with a ratio of 80:20, and then disintegrate, dilute, and make paper according to the above-mentioned ^embodiment . mm cigarettes with high air permeability forming paper.

The cigarette filter tip made of the high-air-permeability forming paper has good air permeability, high tensile strength and obvious coke reduction effect.
