Problems solved by technology

On the contrary, starch-based adhesives have poor viscosity stability due to their own gelation phenomenon, and the gelation phenomenon is more intense at high concentrations, resulting in a gradual increase in viscosity with the prolongation of storage time, and even formation of gel and lose fluidity
Therefore, the gelatinization phenomenon seriously affects the viscosity stability and performance of starch glue.
In addition, starch glue is also vulnerable to microbial attack during storage, resulting in rancidity and loss of cohesion.
These are all factors that affect the viscosity stability of starch glue, and are also important factors that affect whether starch glue can be used normally. At the same time, it is also an important reason why starch-based cigarette glue has not been used in the market so far, although there have been many domestic cigarette glue in the past.

[0038] Raw materials: 100g waxy corn starch, 12g urea, 0.6g hydrochloric acid. Make urea into a 30% aqueous solution, hydrochloric acid into a 5% aqueous solution, mix and stir the waxy cornstarch evenly, react at 140°C for 2 hours, dry and pulverize the obtained reaction product, and obtain urea-modified waxy corn starch.

[0039] Mix 10 g of the urea-modified waxy cornstarch prepared above, 70 g of esterified and degraded waxy cornstarch, 20 g of modified tamarind powder and an appropriate amount of potassium sorbate preservative at room temperature to make a cigarette rubber powder.

[0040] The rubber powder and water were mixed and stirred for 1 hour according to the ratio of 1:1.2 and 1:0.95 respectively, to obtain glue solutions with viscosities of about 550mPa·s and about 3300mPa·s (25°C), and the viscosity was stored at room temperature for 1 month The rate of change i...

Embodiment 3

[0042] Embodiment 3: be used for the lapping glue of high-speed cigarette machine or joint glue

[0043] Raw materials: 100g waxy corn starch, 10g urea, 1g hydrochloric acid. Make urea into a 30% aqueous solution, hydrochloric acid into a 5% aqueous solution, mix and stir the waxy cornstarch evenly, react at 110°C for 4 hours, dry and pulverize the obtained reaction product, and obtain urea-modified waxy corn starch.

[0044] Mix 80 g of urea-modified waxy corn starch prepared above, 15 g of degraded waxy corn starch, 5 g of modified tamarind seed powder and an appropriate amount of potassium sorbate preservative at room temperature to make starch cigarette glue pink.

[0045] The rubber powder and water (purified water or deionized water) were mixed and stirred for 1 hour at a ratio of 1:1.1 and 1:0.9 respectively to obtain glue solutions with viscosities of about 500mPa·s and about 3100mPa·s (25°C). The viscosity change rate is less than 10% when stored at room temperatur...

Abstract

The invention relates to a modified starch-based adhesive for a high-speed cigarette making machine. The modified starch-based adhesive comprises, by weight, 10%-80% of urea modification waxiness corn starch and/or a derivative of the urea modification waxiness corn starch, 10%-80% of degraded waxiness corn starch and/or a derivative of the degraded waxiness corn starch, 2%-20% of modified tamarindus powder and a corrosion remover.

Description

technical field [0001] The invention relates to an adhesive for cigarettes (also known as cigarette glue) in the tobacco industry, in particular to a powdery modified starch-based adhesive, which is suitable for producing cigarettes in various types of high-speed cigarette machines. Background technique [0002] Adhesive / cigarette glue is an indispensable auxiliary material in cigarette production. Adhesive / cigarette glue must be used in almost every cigarette production process, which mainly includes: lap glue, mouthpiece glue, filter rod center line glue, packaging glue and aluminum foil compounding Glue etc. Before the advent of the high-speed cigarette machine, the cigarette speed of the original cigarette machine can only reach one or two thousand per minute, and the cigarette glue used is some natural materials, such as starch, dextrin and natron. After entering the 1970s, high-speed cigarette rolling machines with a cigarette speed of 4,000 to 5,000 sticks per minute...
