A non-sticking lip tipping paper is disclosed that includes a base paper, a color layer and a surface coating. The color layer is formed by printing and drying a color ink on the base paper; the surface coating includes a water-based glue and is coated thereon after drying the color layer. The water-based glue includes the following components by weight: 30-65 parts of a modified water-based resin solution, 10-20 parts of water, 8-15 parts of ethanol, and 5-12 parts of a water-based additive. The water-based additive is a mixture of a wax emulsion and magnesium silicate in a weight ratio of 1:5. A preparation method and a method of applying the non-sticking lip tipping paper are also disclosed.

The present invention relates to a prediction model for a lip sticking force of a cigarette tipping paper, a construction method and a prediction method thereof, which belongs to the technical field of analysis and detection. In the method, the stepwise regression analysis is performed on the lip sticking force and values of the dynamic friction coefficient and the grammage of the cigarette tipping paper to obtain a model for predicting the lip sticking force of the cigarette tipping paper. When checking the accuracy of the model, it is found that the predicted value and the measured value basically fall near the 1:1 line, Rindex is 0.99, and the normalized root mean square error (nRMSE) is 2.64%. The present invention provides a method capable of quickly and simply quantifying a sticking force of the cigarette tipper paper to lips.

A modified carbon material, including a carbonaceous material and a water-insoluble modifier combined with the carbonaceous material, wherein the water-insoluble modifier is CuO, the carbonaceous material is one of or a mixture of biomass carbon or carbon black, a mass of the water-insoluble modifier is being 0.1-10 wt % of the carbonaceous material. The method for preparing the modified carbon material includes: (1) soaking the carbonaceous material in a copper sulfate solution for 5 to 36 hours, and (2) adding an alkali solution into a solution obtained in step (1) to provide a pH value &#x2265;12, and after keeping the pH value for 0.5 to 2 hours, filtering and drying to obtain a solid. (3) using the carbonaceous material as a combustion heat source to reduce the ignition temperature, increase or reduce the peak thermal power temperature.
