Description
Technical field
The present invention relates to a kind of environment-friendly type high-speed packaging glue and preparation method thereof, be specifically related to a kind of cigarette with environment-friendly type high-speed packaging glue and copolymerization preparation method thereof, belong to cigarette and stick with glue the agent field.
Background technology
Cigarette with the main tap mouth of glue glue, overlapping glue, pack four kinds, glue and mouth rod moulding glue, in use desired viscosity is different with glue for every kind of cigarette, what wherein be used for cigarette package is packing glue.In recent years the cigarette packer speed of a motor vehicle of China generally brought up to 1000 boxes/minute more than, and can packing glue adapt to de-luxe compartment entrucking speed mainly by its tack and hold viscosity and decide, and good tack can make cigarette glue can keep the machine of the walking performance of excellence on high-speed packaging machine.The viscosity of packing glue is 1500-1800mPa.s; the main method of Production and Packaging glue is do polymerization or be mixed take EVA (EVA) or PVAc (polyvinyl acetate (PVA)) as main body; and the viscosity of EVA or other binder main body is only the 500-1000mPa.s left and right; usually when adding a certain amount of polyvinyl alcohol (being called for short PVA) protect and improve viscosity for colloid provides; but because the oh group in PVA easily absorbs water; for increasing the water tolerance of packing glue; must seal hydroxyl, modal method is to adopt the PVA acetals to realize.Adopt the PVA formal as the modification tackifier as Hou Qiongzai " the emulsion modified production High Speed Cigarette Adhesives of EVA ", adopt the PVA acetal to make the High Speed Cigarette Adhesives of water-tolerant as emulsifying agent.
In addition, softening agent is also very important for the preparation of packing glue, and the interpolation of softening agent can reduce the second-order transition temperature of superpolymer, increases the snappiness of superpolymer, also can improve the adhesiveproperties of packing glue, improves curing speed and even can play certain water-fast effect.Domestic cigarette glue uses phthalate mostly at present, has all adopted dibutyl phthalate as softening agent as patent application CN201110328602 and CN92109062 when preparing cigarette glue.But because aldehydes and phthalate have larger harm to people's health or environment, also clearly define in cigarette glue the content about aldehydes and phthalate material in four cigarette standards of China.
Therefore, if can develop that a kind of cost is low, the harm of eliminating aldehydes and phthalate material, have good tack, water tolerance and winter hardiness, and the suitable cigarette packer speed of a motor vehicle greater than 1200 boxes/minute the environmental protection package glue of the machine of walking performance, will be to the great significance of the tobacco industry of China.
Summary of the invention
The present invention does not adopt the method sealing hydroxyl of PVA acetals take modified polyvinyl acetate emulsion as base-material, by the polyethylene vinyl acetate emulsion that is mixed (hereinafter to be referred as the EVA emulsion), utilizes the adjacent butyl benzenesulfonamide class of the internal plasticization replacement softening agent of EVA emulsion; Modified polyvinyl acetate emulsion is by adding the organosilicon alkanes monomer that can improve its water tolerance and the acrylic ester monomer that can improve tack and winter hardiness and Acrylic Acid Monomer to make; Gained is packed the glue environmental protection, is had good tack, water tolerance and winter hardiness, can keep the excellent machine of walking performance on high-speed cigarette machine.
To achieve these goals, the present invention is by the following technical solutions:
