Problems solved by technology

However, its viscosity is suitable for glue spraying equipment with low solid content, and the drying speed is too slow, so it cannot be applied to high-speed coiling equipment above 12,000 pieces / min.
[0007] The application number is 201410018852.3, which discloses an environmentally friendly starch cigarette glue, which is prepared from safe and harmless materials, but because it is only mixed with hot water and other ingredients in the preparation process, it is easy to produce block, and the stability of the cigarette glue produced by it is poor, and the viscosity value of the cigarette glue produced by it reaches more than 1000, so the product will have problems such as poor spraying, discontinuous glue coating, and affecting production speed.

Embodiment 1

[0053] 1. Ratio preparation

[0054] Weigh 120g of waxy corn starch, 200g of deionized water, 10g of maleic acid, 3.6g of sodium hydroxide, 2g of sodium dihydrogen phosphate, 6g of sucrose, 6g of glycerol, and 2.4g of urea , Sodium dodecylbenzenesulfonate of 2g, the propylene glycol of 2g, the potassium sorbate of 2g, standby.

[0055] 2. The first gelatinization treatment

[0056] Put weighed 120g of waxy cornstarch and 200g of deionized water in a reaction vessel and mix them. After stirring evenly, heat the reaction vessel to raise the temperature of the mixture in the reaction vessel to 50°C, and then add an appropriate amount of hydrogen peroxide into the reaction vessel. The sodium adjusts the pH value of the mixture so that the pH value reaches 8-10, and then the material in the reaction vessel is stirred at a stirring rate of 1000 r / min for 0.5 h to obtain a gelatinized mixture.

[0057] The invention uses waxy starch with relatively good cold solubility, does not ag...

Embodiment 2

[0079] In addition to weighing 160g of waxy cornstarch, 240g of deionized water, 6g of sodium hydroxide, 13.6g of maleic acid, 8g of sucrose, 6g of glycerol, 2.4g of urea, and 2g of dodecyl Except the propylene glycol of sodium benzenesulfonate, 2g, the potassium sorbate of 2g, other are all identical with embodiment 1.

Embodiment 3

[0081] In addition to weighing 180g of waxy cornstarch, 220g of deionized water, 6g of sodium hydroxide, 15.8g of maleic acid, 2g of sodium dihydrogen phosphate, 6g of sucrose, 6g of glycerol, and 3.5g of urea , 2g of sodium dodecylbenzenesulfonate, 2g of propylene glycol, and 2g of potassium sorbate, other are the same as in Example 1.

Abstract

The invention discloses a preparation method of an environment-friendly high-speed starch lap adhesive and the lap adhesive, and relates to the field of chemistry and chemical engineering. The preparation method comprises the following steps: at normal temperature, adding deionized water into basic native starch of a high-branching-content molecular structure, stirring, then carrying out pregelatinization, adding a modifier, and carrying out gelatinization to obtain a completely gelatinized product; carrying out viscosity increasing, stabilizing, corrosion prevention, debubbling and filtering on the completely gelatinized product to obtain the environment-friendly high-speed starch lap adhesive. A main raw material used in the preparation method is a green regenerable material, so that a combustion product is harmless to a human body; furthermore, the environment-friendly high-speed starch lap adhesive prepared with the preparation method has the characteristics of high solid content (45 to 55 percent) and low viscosity (300 to 1,200 mPa.s), is high in flowability and high in drying speed, and can be applied to cigarette production equipment with the speed of 15,000 cigarettes / min to 20,000 cigarettes / min.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a lap glue used for bonding the burning part of a cigarette. Background technique [0002] Lap glue is applied to the bonding of the burning part of the cigarette. Since the lap glue participates in the burning of cigarettes, the safety performance requirements of its components are relatively strict. In the initial stage of the development of cigarette adhesives, the mouth glue is generally made of starch and its derivatives. However, with the rapid development of cigarette production technology and equipment, it has grown from 1,000 sticks / min to the current commonly used 7,000 sticks / min to 15,000 sticks / min. The mouth glue made of starch is not suitable for existing cigarette production equipment due to defects such as long drying time and poor fluidity. [0003] At present, synthetic polymers such as vinyl acetate-ethylene copolymer (VAE) or polyvinyl acetate (PVAc) are ...
