Abstract

The invention discloses capsule oil seepage preventing coating for filler-capsule-type tipping paper and a preparation method of the capsule oil seepage preventing coating. The capsule oil seepage preventing coating is prepared from the following raw materials in parts by weight: 15-30 parts of waterborne polyurethane emulsion, 5-15 parts of styrene-acrylic emulsion, 1-10 parts of vinyl acetate-ethylene copolymer emulsion, 1-5 parts of a waterborne closed isocyanate cross-linking agent, 0.1-1.0 part of a wetting agent, 0.01-0.5 part of a defoamer, 35-80 parts of purified water and an appropriate quantity of PH regulators. The coating is a thermosetting coating system with the additionally added cross-linking agent and without low-surface-energy substances such as waxes, a coating with a three-dimensional reticular dense structure and high surface energy is formed under the heating condition, seepage of filler capsule oil, namely grease, and essence and fragrance molecules is effectively blocked, thus the purpose of preventing seepage of the capsule oil is realized, and meanwhile, it is also ensured that the tipping paper is wetted and firmly bonded by an adhesive in the subsequentusing process.

Description

technical field [0001] The invention relates to coatings, more specifically to an anti-seepage bead oil coating used for popping tipping paper and a preparation method thereof. Background technique [0002] Popping-ball cigarettes refer to a cigarette technology innovation method in which popping beads are embedded in cigarette filters in the form of capsules, and are mainly used in high-end cigarette products. Among them, the pop-up beads are also called fragrance dropping pills, brittle capsules, etc. The pearl oil components contained in them are oil solvents such as glycerides and oil-soluble flavors and fragrances. By wrapping liquid solvents with different fragrances, a variety of fragrance components can be added conveniently , to "coat" some spices that have a strong surface aroma and can highlight the characteristic style of cigarettes, so that they are not easy to volatilize. When you squeeze and pinch the explosive beads during smoking, the bead oil will overflow,...
