A kind of anti-seepage bead oil paint for popping bead type tipping paper and preparation method thereof

Abstract

The invention discloses an anti-seepage bead oil coating used for popping bead-type tipping paper and a preparation method thereof. The ratio of the raw materials used is calculated in parts by weight as follows: 15-30 parts of water-based polyurethane emulsion, 5 parts of styrene-acrylic emulsion -15 parts, 1-10 parts of vinyl acetate-ethylene copolymer emulsion, 1-5 parts of water-based blocked isocyanate crosslinking agent, 0.1-1.0 parts of wetting agent, 0.01-0.5 parts of defoamer, 35-80 parts of purified water, Appropriate amount of PH regulator. The coating of the present invention is a thermosetting coating system that does not contain low surface energy substances such as waxes and other external crosslinking agents. Under heating conditions, a coating with a three-dimensional network dense structure and high surface energy is formed, which effectively blocks the pearl oil. That is, the penetration of oil and flavor and fragrance molecules, so as to achieve the purpose of anti-seepage pearl oil, and also ensure the wetting and firm bonding of the adhesive to the tipping paper during subsequent use.

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,...

Problems solved by technology

However, there is such a low surface energy coating on the inner side of the tipping paper, so that the inner and outer sides of the tipping paper will have poor lap bonding and glue opening during subsequent use, and the so-called "flashing" of the packaging is prone to occur, which seriously affects Cigarette Packing Quality
