Embodiment 1

[0017] Bleached chemical wood pulp is used as raw paper pulp, prepared by beating, purification, screening, and papermaking. In the drying part of the paper machine, flame-retardant ingredients are applied, followed by subsequent drying and cutting to obtain flame-retardant cigarettes. Tipping base paper products.

[0018] Configuration examples of flame retardant components:

[0019] Melamine Phosphate Salt 100g

[0020] Modified starch 35g

[0021] water 1000g

[0022] Dissolve 35 grams of modified starch in 700 grams of water, stir and disperse evenly, heat to 80-90 ° C, gelatinize at this temperature for 20 minutes, add water to dilute to 1000 grams, then add 100 grams of melamine phosphate, continue to stir Dissolved to make soluble night.

[0023] Dosage: 5% to 9% of the solid matter applied to the paper, the concentration of the application liquid depends on the adsorption amount of the base paper, and the two are inversely proportional.

Embodiment 2

[0025] Bleached chemical wood pulp is used as raw paper pulp, prepared by beating, purification, screening, and papermaking. In the drying part of the paper machine, flame-retardant ingredients are applied, followed by subsequent drying and cutting to obtain flame-retardant cigarettes. Tipping base paper products.

[0026] Configuration examples of flame retardant components:

[0027] Melamine polyphosphate 120g

[0028] Modified starch 40g

[0029] water 1000g

[0030] Dissolve 40 grams of modified starch in 700 grams of water, stir and disperse evenly, heat to 80-90°C, gelatinize at this temperature for 20 minutes, add water to dilute to 1000 grams, then add 120 grams of melamine polyphosphate, continue Stir to further dissolve to make a solution.

[0031] Dosage: 5%-9% of the solid matter applied to the paper, the concentration of the application liquid depends on the adsorption amount of the base paper, and the two are inversely proportional.

Embodiment 3

[0033] Bleached chemical wood pulp is used as raw paper pulp, prepared by beating, purification, screening, and papermaking. In the drying part of the paper machine, flame-retardant ingredients are applied, followed by subsequent drying and cutting to obtain flame-retardant cigarettes. Tipping base paper products.

[0034] Configuration examples of flame retardant components:

[0035] Melamine polyphosphate 60g

[0036] Melamine Phosphate Salt 50g

[0037] Modified starch 25g

[0038] water 1000g

[0039] Dissolve 25 grams of modified starch in 700 grams of water, stir and disperse evenly, heat to 80-90°C, gelatinize at this temperature for 20 minutes, add water to dilute to 1000 grams, then add 60 grams of melamine polyphosphate and melamine phosphate 50g of salt, continue to stir and further dissolve to make a solution.

[0040] Dosage: 5%-9% of the solid matter applied to the paper, the concentration of the application liquid depends on the adsorption amount of the bas...

Abstract

The invention relates to a method for preparing tipping paper for a cigarette, in particular to a method for preparing flame-retardant safe raw tipping paper for the cigarette. The method comprises the following steps of: pulping bleached chemical wood pulp serving as the pulp of the raw paper, purifying, screening, and papermaking, wherein a flame-retardant component is applied to a drying part of a papermaking machine and consists of modified starch and a halogen-free phosphorus-nitrogen flame retardant in a weight ratio of 1:1-1:8, and the phosphorus-nitrogen flame retardant is one or more of melamine phosphate, melamine polyphosphate, 2,4,8,10-tetraoxo-3,9-diphosphaspiro[5,5]undecane-3,9-dioxo-3,9-dimelamine salt and di(2,6,7-trioxo-1-phospho-bicyclo[2,2,2]octane-1-oxomethyl)melamine phosphate. The product has the advantages that: the process is simple, the product has stable quality and a prominent flame-retardant effect, and is an updated and upgraded product of the raw tipping paper for the cigarette, and the flame-retardant property and surface strength of the paper are improved.

Description

[0001] This patent application is a divisional application of an invention patent application (application number: 201010141780.3, application date: April 07, 2010, invention and creation name: a fire-resistant and safe cigarette tipping base paper and its preparation method). technical field [0002] The invention relates to a method for preparing cigarette tipping paper. Background technique [0003] No matter which country you are in, randomly discarded cigarette butts are one of the important causes of fires. When cigarette butts fall on the ground, they can lead to house burning, factory explosions and forest fires, causing heavy losses in life and property. Cigarette tipping base paper is a special base paper for joining filter tips and cigarettes when producing filter cigarettes. The cigarette tipping base paper used in the past does not have flame retardant properties, leaving a large fire hazard to the natural environment. [0004] The Chinese invention patent (app...
