preparation example Construction

[0033] see Figure 4 , the present invention further provides a method for preparing cigarette tipping paper, comprising:

[0034] S11, providing a base paper for tipping paper, the base paper for tipping paper has opposite first and second sides;

[0035] S12, providing an oil-repellent coating, printing or coating the oil-repellent coating on the first surface to obtain a first oil-repellent layer;

[0036] S13, providing an oleophobic and hydrophilic coating, the oleophobic and hydrophilic coating and the above-mentioned oil-repellent coating respectively have a compatible resin matrix;

[0037] S14, printing or coating the oleophobic and hydrophilic coating on the first oil-repellent layer to prepare a first oleophobic and hydrophilic layer, and obtaining the tipping paper for cigarettes.

[0038]In step S12, after the oil-repellent paint is printed or coated on the base paper of the tipping paper, all the solvents in the oil-repellent paint are volatilized, so as to obt...

Embodiment 1

[0058] The formula (mass percentage) of oleophobic hydrophilic coating in the present embodiment is as follows: 30% aqueous polycarbonate, 15% activated calcium carbonate, 25% ethanol, 26% water, 1% smooth agent, 1% anti-settling agent, 1% leveling agent, 1% defoamer.

Abstract

The present invention provides a water -sparse hydrophilic coating for smoke, including connecting materials, inorganic fillers, ethanol, and water. Among them, at least one of the connected materials from water -based polycarbonate and water -based polyurethane is selected, At least one of the inorganic filler is selected from the active calcium carbonate and talc powder, which is 15-30 % of the quality of the connector. The quality of the inorganic filler is 15-30 %.The percentage is 20-30 %, and the quality of the water is 20-30 %.The present invention further provides a preparation method for oil -sparse hydrophilic coatings.The oil -related water coatings provided by the present invention can not only make the cigarettes completely block the exudate of the liquid fat, but also be able to adapt to the packaging volume of the cigarette roll connection, and the smoke is equipped with a paper loading paper.The moisture content can always be controlled within the specified range.

Description

technical field [0001] The invention relates to the field of cigarettes, in particular to an oleophobic and hydrophilic coating for cigarette tipping paper and a preparation method thereof. Background technique [0002] With the development of society and the progress of civilization, cigarettes are no longer simply cigarettes, but a symbol of identity. More and more people choose high-end cigarettes to improve their taste, and they are more pursuing functional products. Cigarettes, various cigarettes with anti-counterfeiting functions, laser functions, fluorescent functions, anti-penetration functions, etc. continue to appear in the cigarette market. Recently launched by Yunnan Tobacco Factory, Hefei Tobacco Factory and Wuhu Tobacco Factory, the popcorn cigarettes are very popular among smokers. This new type of puffed bead smoke is achieved by pinching the puffed puffed capsules embedded in the cigarette bundle with fingers to increase the aroma and taste of the cigarette...
