Embodiment 1

[0030] 20g of acid-hydrolyzed cellulose acetate treated by ball milling, 6g of polyethylene glycol 400, 2g of polyvinyl acetate emulsion, 2g of maltodextrin, 0.5g of nano light calcium carbonate, 0.1g of potassium sorbate, and 0.1g of dimethyl The base silicone oil was added to 70g of water in turn, and stirred for 1 hour. The resulting coating solution had a solids content of 28.3% and a Brookfield viscosity of 120 cps (25°C).

Embodiment 2

[0032] 30g of ball-milled enzymatic cellulose acetate, 15g of polyethylene glycol 600, 1g of polyvinyl acetate emulsion, 1g of maltodextrin, 0.7g of nanometer light calcium carbonate, 0.2g of potassium sorbate, and 0.2g of dimethyl The base silicone oil was added to 52g of water in turn, and stirred for 1 hour. The resulting coating solution had a solids content of 45.6% and a Brookfield viscosity of 360 cps (25°C).

Embodiment 3

[0034] 35g of ball-milled oxidized cellulose acetate, 6g of polyethylene glycol 200, 2g of polyethylene glycol 400, 5g of polyvinyl acetate emulsion, 3g of maltodextrin, 1g of nano light calcium carbonate, 0.4g of potassium sorbate , 0.4g of simethicone oil were added to 47g of water in sequence, and stirred for 1 hour. The resulting coating solution had a solids content of 48.2% and a Brookfield viscosity of 455 cps (25°C).

Abstract

A coating solution for reducing the release of phenol in the mainstream smoke of paper filter stick cigarettes, characterized in that it is made of the following raw materials: cellulose derivatives, wetting agents, binders, thickeners, dispersion stabilizers Agents, preservatives and defoamers are added to water in sequence. The use of the coating solution can effectively reduce the phenol release in the mainstream smoke of paper filter stick cigarettes, and the selective reduction rate of phenol can be as high as 40% without affecting the sensory quality of cigarettes. In addition, the raw materials used in the coating solution come from a wide range of sources , Green environmental protection, low cost.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and specifically provides a coating solution for reducing the amount of phenol released in the mainstream smoke of paper filter-stick cigarettes. The amount of phenol released in the flue gas is high, and the raw materials used in the coating solution have a wide range of sources, are environmentally friendly and low in cost. Background technique [0002] Paper filter rods were born in the 1920s. Due to many reasons such as the limitation of the technical level of the cigarette filter rod industry, cigarette paper filter rods have not been widely used. Compared with the currently widely used cellulose acetate filter rod, the paper filter rod has the advantages of excellent tar nicotine filtering ability, lower price and the like. However, paper filter sticks also have some disadvantages, such as heavy "paper smell", dry smoke, thermal collapse, and poor interception effect on harmful componen...
