Abstract

The invention relates to a coating composition capable of regulating the surface friction coefficient of an inner liner for cigarettes. The coating composition is composed of the following components in parts by weight: 10-40 parts of hard acrylic resin, 10-40 parts of soft acrylic resin, 3-18 parts of silicon-containing modified acrylic resin, 5-15 parts of hand feel resin, 0.2-0.5 part of auxiliaries, 10-30 parts of ethanol and 20-40 parts of deionized water. Compared with the prior art, the composition provided by the invention is capable of realizing the regulation of the surface friction coefficient of the coating layer because the soft acrylic resin and the hard acrylic resin are taken as a major part in combination with the silicon-containing modified acrylic resin and the hand feel resin; as a result, the composition is capable of meeting the requirements of different cigarette packing processes for the surface friction coefficient of the inner liner and satisfying the own scratch resistance of the inner liner.

Description

technical field [0001] The invention relates to a coating used for the surface coating of inner lining paper for cigarettes, in particular to a coating composition capable of adjusting the surface friction coefficient of inner lining paper for cigarettes. Background technique [0002] The surface coating of the inner lining paper for cigarettes has barrier properties to moisture and gas. At the same time, the surface coating has a certain influence on the friction coefficient of the inner lining paper. A low friction coefficient of the surface coating will cause slippage of the lining paper during cigarette wrapping and winding. A high friction coefficient of the surface coating will reduce the scratch resistance of the coating and affect the smoothness of the surface. The existing technology is to adjust the friction coefficient of the lining paper surface by adding some additives into the coating; however, due to the overall low surface tension of the added additives, it i...
