* Unless otherwise specified, the percentages used in the present invention are all mass percentages.

An environment-friendly inner lining paper for cigarettes is characterized in that: a food-grade microcrystalline wax coating is applied between two layers of conventional low-gram weight water-resistant glossy paper; the food-grade microcrystalline wax coating consists of the following The raw materials are prepared in parts by weight: 20 parts of wood wax, 50 parts of rice bran wax, 5 parts of palm wax, 5 parts of candelilla wax and 15 parts of sugarcane wax.

The method for preparing the above-mentioned environment-friendly lining paper for cigarettes comprises the following steps:

(1) Weigh 20 parts of wood wax, 50 parts of rice bran wax, 5 parts of palm wax, 5 parts of candelilla wax and 15 parts of sugarcane wax by weight, and obtain food-grade microcrystalline wax through refined synthesis, for subsequent use; food-grade microcrystalline wax The environmental conditions for wax preparation are temperature (23±2)°C, relative humidity (50±10)%;

(2) Heat the food-grade microcrystalline wax into a solution at a temperature of 80 to 85°C in a sealed hot-melt device, and then cool the solution to a constant temperature of 70°C for standby;

(3) Apply the food-grade microcrystalline wax solution obtained in step (2) to any surface of conventional low-gram weight water-resistant glossy paper, and stick the coated surfaces of the two glossy papers together to obtain the desired Environmentally friendly lining paper for cigarettes.

Compared with the prior art, the present invention has the following beneficial effects:

1. The present invention makes up for the gap in the composite process of cigarette lining paper, and applies food-grade microcrystalline wax to cigarette lining paper, which can eliminate the dependence on aluminum foil when cigarette lining paper is composited, and enrich the cigarette lining. The intrinsic form of paper improves the product's barrier resistance, oxidation resistance, fragrance retention, moisture retention and environmental protection compared with existing products.

2. The invention has low cost, simple and convenient preparation method and good application prospect.

Detailed ways

The present invention will be further described in detail below in conjunction with the examples, but the examples are not intended to limit the technical solution of the present invention. Anyone familiar with the technical field within the technical scope disclosed in the present invention, according to the scheme of the present invention and its inventive concepts to make equivalent replacements or changes shall be covered by the protection scope of the present invention.

Example 1

Weigh 20 parts of wood wax, 50 parts of rice bran wax, 5 parts of palm wax, 5 parts of candelilla wax, and 15 parts of sugarcane wax in parts by weight. Separation from the residue, refined and synthesized solid content: 1 part of 100% food-grade microcrystalline wax;

Use a sealed hot-melt device with a temperature of 80-85°C to melt the food-grade microcrystalline wax into a solution, and cool the solution down to 70°C at a constant temperature for later use to obtain a food-grade microcrystalline wax hot-melt coating liquid ;

After the process parameters of the paper compounding equipment are adjusted, the above-mentioned coating solution is coated and heated by the roller of the paper machine, and then adsorbed on the surface of the base paper of the inner lining paper to obtain the inner lining paper for cigarettes.
