Embodiment 1

[0017] Disperse 100g polymalic acid in 2L water, slowly add 50ml (200mg / ml) KOH aqueous solution dropwise into the above polymalic acid solution, continue stirring for 10min to obtain a transparent solution, add 4g zinc acetate and 2g ferric lactate 100ml of aqueous solution, the temperature was gradually raised to 50°C, kept for 1 hour, and the temperature of the reaction solution was lowered to 20°C. The reaction solution was slowly added dropwise to 3L of acetone under stirring, precipitated and filtered. The filter cake was washed successively with 200ml of acetone and 400ml of ether, and dried.

Embodiment 2

[0019] Disperse 100g of polymalic acid in 2L of water, slowly add 50ml (200mg / ml) KOH aqueous solution dropwise to the above polymalic acid solution, continue stirring for 10min to obtain a transparent solution, add 6g of zinc acetate and 1g of germanium tartrate 100ml of aqueous solution, the temperature was gradually raised to 60°C, kept for 2 hours, and the temperature of the reaction solution was lowered to 20°C. The reaction solution was slowly added dropwise to 3L of acetone under stirring, precipitated and filtered. The filter cake was washed successively with 700ml of acetone and 400ml of ether, and dried.

Embodiment 3

[0021] Disperse 100g of polymalic acid in 2L of water, slowly drop 70ml (200mg / ml) of KOH aqueous solution into the above polymalic acid solution, and continue stirring for 10min to obtain a transparent solution, add 8g of zinc acetate and 1g of ferric citrate 100ml of aqueous solution, the temperature was gradually raised to 50°C, kept for 1.5 hours, and the temperature of the reaction solution was lowered to 20°C. The reaction solution was slowly added dropwise to 5L of acetone under stirring, precipitated and filtered. The filter cake was washed successively with 600ml of acetone and 400ml of ether, and dried.

Abstract

The invention relates to a preparation method of cigarette paper additive, which belongs to the field of paper chemicals and comprises the following steps that: dispersing polymalic acid into water by 0.5 to 20mg/ml; dripping KOH solution into the water solution of the polymalic acid, and stirring the mixture; adding the water solution of metal salt into transparent solution and stirring, increasing the temperature to 40 to 60DEG C, maintaining the temperature for 1 to 2h, reducing the temperature of reaction solution to 20DEG C, slowly dripping the reaction solution into acetone while stirring, precipitating, filtering, and washing and drying a filter cake sequentially with acetone and ether; the ratio of the materials of the steps is respectively as follows: polymalic acid: KOH=100:4 to 40, m/m; KOH:metal salt=100:6 to 70, m/m; and the metal salts is one or more types of zinc acetate, zinc lactate, iron lactate, ferric citrate, germanium manganese acetate and tartaric acid. The preparation method of the cigarette paper additive has simple method and mild reaction conditions, and the prepared cigarette paper additive can be quickly dissolved in water.

Description

technical field [0001] The invention belongs to the field of papermaking chemicals, in particular to a method for preparing cigarette paper additives. Background technique [0002] Cigarette paper is an important part of cigarettes. In addition to wrapping shredded tobacco and making it into cigarettes, cigarette paper also has the functions of controlling the burning speed of cigarettes and retaining soot. In an 85mm long regular low-tar cigarette design, the cigarette paper accounts for about 5% of the total weight of the rod. Although this ratio is small, it has a great influence on the static combustion rate, ventilation, the number of puffs, the pressure drop of the tobacco rod (and even the whole cigarette), and the volume of main and side stream smoke. Cigarette paper consists of inorganic fillers, cellulose and several additives. The commonly used inorganic filler is calcium carbonate, and some special fillers can be used to reduce the amount of sidestream smoke. ...
