Embodiment 1

[0008] Example 1 20g carboxymethylcellulose, 5g Tween-80, 5g sodium carboxymethylcellulose, 3g sodium hexametaphosphate, 3g guar gum, 2g paraben and its sodium salt, 3g higher alcohol The fatty acid ester complexes were added to 70g of water in turn, and stirred for 1 hour. The resulting coating solution had a solid content of 28.3% and a Brookfield viscosity of 120 cps (25°C).

Embodiment 2

[0009] Example 2 30g carboxymethylcellulose, 6g Tween-80, 4g sodium carboxymethylcellulose, 4g sodium hexametaphosphate, 6g guar gum, 4g paraben and its sodium salt, 1g higher alcohol Add the fatty acid ester complex into 52g of water in turn, and stir for 1 hour. The resulting coating solution had a solid content of 45.6% and a Brookfield viscosity of 360 cps (25°C). Example 3 35g carboxymethylcellulose, 12g Tween-80, 9g sodium carboxymethylcellulose, sodium hexametaphosphate 1-10%, 9g guar gum, 2g paraben and its sodium salt, 5g The higher carbon alcohol fatty acid ester complex was added into 47g of water in turn, 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

The invention provides a coating liquid for reducing the tar release amount in paper filter rod type cigarette mainstream smoke, wherein the coating liquid comprises: water, carboxymethyl cellulose, Tween-80, sodium carboxymethyl cellulose, sodium hexametaphosphate, guar gum, paraben and a sodium salt thereof, and a high alcohol fatty acid ester complex. According to the present invention, by using the coating liquid, the tar release amount in paper filter rod type cigarette mainstream smoke can be effectively reduced, and the sensory quality of the cigarette cannot be affected; and the raw materials of the coating liquid have characteristics of wide source, environmental protection and 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 tar released in mainstream smoke of paper filter stick cigarettes. 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. However, paper filter rods also have some disadvantages, such as heavy "paper smell", dry smoke, thermal collapse, and poor interception effect on harmful components such as tar in the smoke. As the society continues to pay attention to tar reduction and harm reduction, it is more important to reduce the amount of tar released in cigarette smoke. At present, there are many studies on the reduction of tar in paper filter rods. For example, the US 5671757 patent uses 25% to 50% Lyocell fibers and 50% to 75% wood pulp fibers to be m...
