Problems solved by technology

The method is complex in process, and the yield of the synthesis reaction is low. After the reaction, there are many residual acrylate monomers, which are difficult to remove. The acrylate monomers have a strong smell and the total VOC content is relatively high.
[0010] It can be seen that with the introduction of packaging equipment, the packaging speed has been greatly improved, and there are many types of packaging. However, the current cigarette packaging adhesives have low initial adhesion and poor wettability, which easily lead to greater elasticity or adhesion. The packaging with small surface has problems of springing and dislocation during the production process; the high content of residual monomers is not environmentally friendly and cannot meet the requirements of high-speed packaging equipment

Embodiment 1

[0066] 1. Preparation of polyvinyl alcohol aqueous solution

[0067] At room temperature, weigh 80g of water and add it to the reaction vessel, start stirring, then weigh 20g of polyvinyl alcohol and slowly add it to the reaction vessel, stir and disperse evenly and when there is swelling, start to heat up and heat to 85°C-90°C , keep warm for 2 hours to obtain polyvinyl alcohol aqueous solution.

[0068] Specifically, the degree of alcoholysis of the polyvinyl alcohol is 80-98%, and the degree of polymerization is 500-3000.

[0069] Polyvinyl alcohol aqueous solution has certain viscosity, water solubility, surface activity and cohesiveness, but the above-mentioned properties of polyvinyl alcohol will vary greatly with the degree of alcoholysis, for example, its surface activity and surface colloidal effect will change with alcoholysis The protective colloid ability increases with the increase of molecular weight, while the surface activity decreases with the increase of mol...

Embodiment 2

[0086] Except that VAE emulsion, polyvinyl alcohol aqueous solution, plasticizer, tackifier, surface wetting agent, defoamer and preservative are taken by weight in the following proportions, others are all the same as in Example 1:

[0088]

Embodiment 3

[0090] Except that VAE emulsion, polyvinyl alcohol aqueous solution, plasticizer, tackifier, surface wetting agent, defoamer and preservative are taken by weight in the following proportions, others are all the same as in Example 1:

Abstract

The invention discloses a wide-adaptability cigarette packaging adhesive and a preparation method thereof, and relates to the technical field of adhesives, and the packaging adhesive disclosed by theinvention comprises an antifoaming agent added into a VAE emulsion and a polyvinyl alcohol aqueous solution, a preservative and an auxiliary agent, wherein the auxiliary agent comprises the followingcomponents in parts by weight: 5-10 parts of a plasticizer, 0-5 parts of a tackifier, and 0.1-0.5 part of a surface wetting agent. According to the present invention, the components are respectively added to the VAE emulsion to carry out different stirring so as to obtain the wide-adaptability cigarette packaging adhesive. The preparation method is simple, the cost is low, the requirement on the material is low, and the excellent adhesion effect can be provided even for the packaging material with the small effective adhesion area; and particularly, the shutdown frequency and nozzle blockage in the cigarette production process are reduced, and the influence of temperature is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a packaging adhesive for cigarettes with a wide application range and a preparation method thereof. Background technique [0002] Cigarette glue is a special adhesive used in cigarette bonding and forming. It is an indispensable raw and auxiliary material in the cigarette manufacturing process. According to the different bonding parts, cigarette glue includes filter rod centerline glue, joint glue, lap glue There are four types of packaging glue and packaging glue. Packaging glue is used for packaging materials such as small box paper, carton paper and sealing paper. [0003] Cigarette packaging adhesive belongs to tobacco adhesives and is one of the important materials for cigarette packaging. It is mainly used to bond packaging materials such as small box label paper, carton paper and sealing paper. The proportion of materials used is small, but it has a great impact on the ...
