Problems solved by technology

Combined with the control of the inherent safety indicators of cigarette lap glue and the improvement of the performance application requirements of high-speed cigarette machines, most domestic research institutions, latex manufacturers, and scholars adopt blending modification, copolymerization modification, cross-linking modification, and emulsifier modification. Research on improving the performance of latex for cigarettes with technologies such as chemical properties and microemulsion preparation, but the effect is still not ideal

preparation example Construction

[0046] The preparation method of cigarette mouthpiece glue and lap glue of the present invention comprises the following steps:

[0047] (1) First prepare vinyl acetate-ethylene copolymer and water at a mass ratio of 1:5 to form a vinyl acetate-ethylene copolymer emulsion, and heat it to 45°C.

[0048] (2) Melt lotus root starch into 60°C water at a mass ratio of 1:5, and stir thoroughly to form a suspension.

[0049] (3) During the stirring process, add vinyl acetate-ethylene copolymer emulsion to lotus root starch suspension in proportion; add ethanol, SE-11 sucrose fatty acid ester in sequence, and then add 60°C hot water to dilute to the specified ratio, and cool Then it can be packaged to become a finished product.

Embodiment 1

[0051] According to the test and analysis of a certain cigarette machine model (vehicle speed 12000 cigarettes / min), we designed a fast-curing mouth glue and lap glue respectively for this model of cigarette making machine. The design viscosity of the mouth glue is 850 centipoise, and The design viscosity is 550 centipoise, and the original formula design ratio is as follows:

[0052] Mouth glue (No. CVAE04) ingredient list

[0053] ingredients Proportion Vinyl acetate-ethylene copolymer emulsion (vinyl acetate-ethylene copolymer ratio 45%) 15％ lotus root starch 4％ water 78％ ethanol 2％ SE-11 Sucrose Fatty Acid Ester 1％

[0054] Viscosity 850 centipoise (temperature: 25±2°C, humidity 60±5%, standard atmospheric pressure).

[0055] Lap mouth glue (No. CVAE08) ingredient list

[0056] ingredients Proportion Vinyl acetate-ethylene copolymer emulsion (vinyl acetate-ethylene copolymer ratio 45%) 10％ lotus root star...

Abstract

The invention relates to a cigarette lap adhesive, a tip assembling adhesive and a preparation method thereof. The invention belongs to the technical field of cigarette adhesives. The tip assembling adhesive and the cigarette lap adhesive are high in safety, can be directly used on a cigarette making machine without being cured or semi-cured, and are cured and dried by soldering iron of the cigarette making machine, the coating effective rate reaches 100%, and the problems of cracking, air leakage and the like are avoided. The contradiction between the adhesive property and the viscosity of the cigarette adhesive is effectively solved, the high-speed production requirement of a cigarette making machine can be met, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of cigarette glue, and in particular relates to a cigarette mouthpiece glue and lap glue and a preparation method thereof. Background technique [0002] The cigarette forming process is divided into the following steps: [0003] Step 1: The shredded tobacco passes through the cigarette machine feeding system, and the shredded tobacco is uniformly and stably supplied in a quantitative manner; Step 2: The shredded tobacco passes through the forming system to form a uniform bundle of shredded tobacco; Step 3: Through the bong of the cigarette making machine, it is wrapped with cigarette paper to form a tobacco rod; 4: Tobacco rods pass through the cutting system and rubbing system, and are connected with filters to form cigarettes. In step 3 above, after wrapping the cut tobacco with the cigarette paper, it is necessary to coat the edge of the cigarette paper with cigarette lapping glue by the gluing nozzle an...
