Abstract

The invention provides coating for environment-friendly tipping paper. The coating is at least prepared from the following components in parts by weight: 20-30 parts of self crosslinking acrylic acidcopolymer resin, 10-20 parts of polyvinyl butyral, 10-20 parts of chitosan, 1-5 parts of ferric oxide red powder, 1-5 parts of ferric oxide yellow powder, 1-2 parts of talcum powder, 4-10 parts of spherical hydroxyapatite, 50-70 parts of pure water, 20-40 parts of ethyl alcohol, 5-15 parts of plant oil, 0.5-1.5 parts of defoaming agent and 0.5-1.5 parts of dispersing agent. The coating for environment-friendly tipping paper adopts chitosan to wrap pigment, on the one hand, the color of the pigment is kept, on the other hand, the possibility that the pigment is directly contacted with the humanbody is reduced, so that no harm is made to the human body. Meanwhile, chitosan and spherical hydroxyapatite are added into the network formed by the self crosslinking acrylic acid copolymer resin and polyvinyl butyral, thus the coating can absorb tar and fume, and the harms to the human body are reduced.

Description

technical field [0001] The invention relates to the field of cigarettes, in particular to a paint for environmental-friendly tipping paper. Background technique [0002] Tipping paper, a cigarette packaging material used as the outer packaging of filter cigarette tip sticks, is a special industrial paper. The name of tipping paper comes from Japan. In the early 20th century, Tohoku Shiko Co., Ltd. in Sendai, Japan produced this paper for the first time. It was named tipping paper because its appearance was similar to the skin of a local plant called tipping pine. In the 1930s, tipping paper was sold to Shanghai, and its name was introduced to China. The current standard name is tipping paper; the unprinted paper produced is called white tipping base paper or tipping base paper. [0003] The tipping paper is in direct contact with the smoker's lips, so the printing ink and coating of the tipping paper must be non-toxic, meet food hygiene standards, and have certain water re...
