Description
Technical Field
The invention belongs to the technical field of cigarettes, relates to a cigarette holder adhesive, and particularly relates to a high-speed spraying holder adhesive for fine cigarettes and a preparation method thereof.
Background
The fine cigarette serving as a Chinese cigarette new product which is rapidly increased has natural advantages in the fields of tar reduction, harm reduction, cost reduction, efficiency improvement and the like, but the conventional method of roller coating and gluing is adopted for the fine cigarette in the production process, and the circumference of the fine cigarette is lower than that of the conventional cigarette and has larger resilience in the cigarette rolling and connecting process. The main reasons are that when the spraying and gluing mode is adopted, the high requirement is provided for the fluidity of the nozzle glue, and the problems of nozzle blockage, high pressure and the like are easily caused by high viscosity and solid content.
Disclosure of Invention
In order to solve the defects of the prior art, the invention aims to provide a fine cigarette high-speed spraying nozzle connecting adhesive and a preparation method thereof.
In order to realize the purpose, the technical scheme of the invention is as follows:
on one hand, the fine cigarette high-speed spraying nozzle connecting glue consists of water and raw materials, wherein the solid content is 24.0-28.0%, and the raw materials consist of the following components in parts by weight: 30 to 50 portions of VAE emulsion, 4 to 10 portions of polyvinyl alcohol, 0.1 to 2 portions of wetting agent, 1 to 2 portions of plasticizer, 0.1 to 0.5 portion of defoaming agent and 0.1 to 0.3 portion of preservative.
The main function of the mouth-connecting glue is to bond the cigarette and the filter tip, and the requirement on safety and sanitation is high. Wherein, the content of the vinyl acetate is required to be less than 400mg/kg, and the VAE emulsion is vinyl acetate (vinyl acetate) -ethylene copolymer emulsion and is the main bonding component of the common nozzle adhesive. When the addition amount of the VAE emulsion is less, the bonding performance of the nozzle adhesive is affected, at the moment, vinyl acetate, methyl methacrylate and/or acrylic acid are required to be added in the traditional method to initiate polymerization to form a copolymer emulsion, but in the preparation process, the problem that the components such as vinyl acetate and the like exceed the standard is caused due to incomplete reaction, and the solid content is still high.
For this purpose, the invention adds polyvinyl alcohol, and uses polyvinyl alcohol and VAE emulsion as main binding component of the nozzle connecting glue. When the cigarette making machine cuts the tipping paper fully coated with the tipping glue, glue scale is easily generated at the cutter. The plasticizer is added to improve the plasticity of the polyvinyl alcohol and the VAE, and simultaneously, the adhesive scale can be softened and is easy to clean, the holding viscosity of the nozzle adhesive can be improved, and the bonding strength of the nozzle adhesive is enhanced. The wetting agent is added, so that the wettability of the tipping glue to the cigarette tipping paper can be improved, the spreading of the tipping glue on the surface of the tipping paper is facilitated, and the firm bonding is facilitated. The defoaming agent is added to eliminate bubbles in the preparation process of the nozzle adhesive, so that the problem that the adhesion between cigarettes and filter tips is not firm due to the introduction of bubbles is avoided.
Meanwhile, VAE emulsions with different glass transition temperatures (Tg) are matched for use, so that the spray nozzle adhesive has better initial adhesion and sustained adhesion.
Experiments show that when the solid content of the nozzle adhesive formed by the VAE emulsion, the polyvinyl alcohol, the wetting agent, the plasticizer, the defoaming agent and the preservative is 24.0-28.0%, the nozzle adhesive still needs to meet the required bonding performance and has proper drying speed, so that the requirement of high-speed rolling connection is met.
On the other hand, the preparation method of the fine cigarette high-speed spray nozzle adhesive comprises the steps of sequentially adding the defoaming agent, the polyvinyl alcohol, the plasticizer and the distilled water under the condition of stirring the VAE emulsion, then uniformly stirring, adding the wetting agent and the preservative, and continuously uniformly stirring.
Specifically, firstly, the VAE emulsion is put into a reaction kettle, stirring is started, the stirring speed is 50-80 r/min, while stirring, the defoaming agent, the polyvinyl alcohol, the plasticizer and the distilled water are sequentially added, the stirring time is 40-90 min, then the wetting agent and the preservative are added, stirring is carried out for 5-20 min, sampling is carried out, the viscosity, the pH value and the solid content of the product are detected, and if the product is qualified, the stirring is stopped, and discharging and packaging are carried out.
In a third aspect, the application of the high-speed spraying nozzle connecting glue for the fine cigarettes in the process of preparing cigarettes by high-speed rolling and connecting cigarettes and filter tips is provided.
The invention has the beneficial effects that:
the spray nozzle adhesive provided by the invention adopts the cooperation of the VAE emulsion, the polyvinyl alcohol, the wetting agent, the plasticizer, the defoaming agent and the preservative, so that the solid content of the nozzle adhesive can be reduced to 24.0-28.0%, and the nozzle adhesive has higher fluidity, better wettability and good bonding effect on different cigarette brands, and can meet the requirement of high-speed rolling and connecting of 10000 cigarettes per minute.
