Abstract

The invention discloses a water base type sealing rubber for tobacco and a method for preparing the water base type sealing rubber for tobacco, which belong to the field of adhesives. The sealing rubber consists of water-based acrylic emulsion, vinyl acetate-dibutyl maleate emulsion, water-based rosin emulsion, water-based assistant and deionized water; and the usages of the components in parts by weight are as follows: 200-400 parts of the water-based acrylic emulsion, 300-500 parts of the vinyl acetate-dibutyl maleate emulsion, 100-200 parts of the water-based rosin emulsion, 2-5 parts of the water-based assistant and the 50-100 parts of the deionized water. The sealing rubber has the characteristics of high initial adhesion, quick drying speed, excellent freezing resistance, small smell and low use cost, and is completely in accordance with the new standard requirements on the sealing rubber for tobacco.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a water-based sealant for cigarettes and a preparation method thereof. Background technique [0002] In the cigarette packaging process, both the small packet box and the carton need to be sealed on the edge or bottom of the box, and the inner box and the outer box also need to be fixed, which requires a sealing glue or edge sealing glue. Its function It is the sealing or shaping effect. This kind of bonding occurs between the paper and the varnished paper surface, the paper surface and the lining paper surface, so it is necessary to choose a suitable adhesive according to the different requirements of these interfaces. There are executable standards, and only adhesives that meet the standards can be listed as options. [0003] my country is a big country in the production and consumption of cigarettes. The annual production of cigarettes is about 34 million large boxes, involving more...
