Embodiment Construction

[0019] A specific implementation example is given below in detail as follows:

[0020] 1. According to the mass ratio, prepare the following raw materials:

[0021] , polyvinyl alcohol, white granular solid, 8 parts,

[0022] , VAE101 (ethylene-vinyl acetate copolymer emulsion), white emulsion, 60 parts,

[0023] , tert-butyl hydroperoxide, the mass concentration is 40% liquid, 0.012 parts,

[0024] , ferrous sulfate, line green powder, 0.010 parts,

[0025] , tri-n-butyl citrate, light yellow liquid, 9 parts;

[0026] 2. Put polyvinyl alcohol into the reaction kettle, add 15 parts of water, stir, and raise the temperature to 85°C until it is completely dissolved;

[0027] 3. Add VAE101 emulsion into the reaction kettle, stir for 15 minutes, and heat to 70°C;

[0028] 4. Add tert-butyl hydroperoxide and ferrous sulfate successively in the reaction kettle, stir, and react for 30 minutes;

[0029] 5. Heat up to 90°C, vacuumize to -0.03MPa, stir, and keep for 20 m...

Abstract

The invention discloses a water-based superspeed cigarette lap adhesive and a preparation method thereof. In the product, ethylene-vinyl acetate copolymer emulsion and polyvinyl alcohol are used as main raw materials; under the action of tert-butyl hydroperoxide-ferrous sulfate, a part of residual vinylacetate is reacted; then the content of the vinylacetate is controlled to be less than 1,000mg / kg by vacuum pumping; the viscosity of an adhesive and the solid content technical index are adjusted by adding lemon butyl acetate plasticizer and water; and the lap adhesive is lacte fluid and has fine and smooth texture, the particles are uniform, the viscosity is 200 to 1,000mPa.S, the solid content is 45 to 55 percent, the pH value is 4 to 6, the content of vinyl acetate is less than 1,000mg / kg, phthalic acid esters are less than 500mg / kg, and the formaldehyde content is less than 50mg / kg. The product is the water-based, safe and environment-friendly, is high in drying speed, and used for lapping and bonding cigarette paper of a superspeed cigarette making machine of a cigarette making factory, and has strong bonding capacity; and the engine speed reaches 12,000 to 17,000 cigarettes / min.

Description

technical field [0001] The invention belongs to an auxiliary material for cigarettes in organic chemical industry, namely a water-based ultra-high-speed mouth glue for cigarettes and a preparation method thereof. Background technique [0002] At present, the speed of cigarette rolling machines in most cigarette factories is generally about 7,000 sticks / minute, and the speed of ultra-high-speed cigarette machines newly introduced by some large tobacco factories is 12,000-17,000 sticks / minute. The ultra-high winding speed requires that the cigarette adhesive must have good fluidity, strong bonding ability and fast drying speed. Traditional tobacco glue based on polyvinyl acetate emulsion is difficult to meet the requirements of lapping technology for cigarette paper for ultra-high-speed cigarette machines. [0003] According to foreign data, both vinyl acetate (acetate) and phthalates have certain harmful effects on the human body. In traditional tobacco adhesives, the conte...
