Description
Technical field
The present invention relates to food packaging applications, specifically, relate to a kind of emulsion binding agent for the outer box of food product pack.
Background technology
At present, a lot of food package boxes comprises directly and the material of Food Contact, and major part all will use tackiness agent.Namely tackiness agent is a kind of subsidiary material that numerous material adhesive can be got up.The kind of tamanori is a lot, and wrapping material is more, and such as adhesive material just comprises solvent-borne type, half oiliness, water-soluble, emulsion-type etc.And want bonding base material to comprise paper, cardboard, plastic material (OPP, PE, PP, PET, BOPP, PS), timber, aluminium foil etc.Those skilled in the art carry out bonding different base material by selecting different tackiness agents, thus realize different materials to form an overall object.
What adhesives industries was advanced by leaps and bounds develop into society provides many virgin rubber kinds, and the toxic raw materials simultaneously used in production process, as formaldehyde, noxious solvent, solidifying agent and other auxiliary agent etc., also brings severe contamination to environment.At present, although the total development trend of tackiness agent is non-organic solvent, but solvent-based adhesive can't reach solvent type level at present completely due to the performance of its excellent technique and adhesiveproperties, particularly non-organic solvent type tackiness agent, and solvent-based adhesive still exists in a long time.Along with China's entry into the WTO, and the raising of Environmental Protection in China consciousness, the technical barrier of the aspects such as environmental protection will highlight.Composite membrane producer and tackiness agent manufacturer should make joint efforts, and improve the state of the art of composite prod.
In today that Environmental awareness and health perception improve day by day, society no longer only pays close attention to the function and application of tackiness agent, further strict to the requirement of the environmental issue of tackiness agent, it is imperative that development meets " environmental protection, health, safety " three large environment-friendly tackiness agent required.For adapting to the needs of society and environmental protection, the kind of tackiness agent, especially food packaging tackiness agent should accelerate to update, and towards Water-borne modification, solidification, solvent free, lowly poisons future development.China Adhesive Industry association declares, at the five-year, China will give priority to environment-friendly type, energy-saving tackiness agent, simultaneously also by research and development high technology content energetically, high added value, high performance tackiness agent product innovation.
Water-base emulsion tackiness agent is the inexorable trend of tackiness agent development, compared with solvent-based adhesive, has solvent-free release, environmental friendliness, nontoxic, non-combustible, use safety, low cost and other advantages.
Along with the sustainable development of China's economic and improving constantly of people's living standard, will be more and more stricter and harsh with selection to the demand of adhesive products, the favor that those performances are good, quality is high, the product of environment-friendly type will be subject to people.
Summary of the invention
The object of this invention is to provide a kind of nonpoisonous and tasteless emulsion binding agent for the outer box of food product pack.
In order to realize the object of the invention, the invention provides a kind of emulsion binding agent, it is characterized in that, it is made up of by weight percentage following composition of raw materials: vinylformic acid mixed emulsion 45% ~ 62%, rosin milk 8% ~ 10%, liquid resin emulsion 30% ~ 45%.
Wherein, described vinylformic acid mixed emulsion is made up of by weight percentage following composition of raw materials: ACRYLIC EMULSION 65% ~ 82%, EVA emulsion 5% ~ 8%, acrylate and vinyl acetate emulsion 10% ~ 30%.
As preferably, described vinylformic acid mixed emulsion is made up of by weight percentage following composition of raw materials: ACRYLIC EMULSION 75%, EVA emulsion 7%, acrylate and vinyl acetate emulsion 18%, and this emulsion can widen the category of emulsion further, as long as do not reduce the cohesive force of formula.
Further, described vinylformic acid mixed emulsion is mixed at normal temperatures ACRYLIC EMULSION, EVA emulsion and acrylate and vinyl acetate emulsion, uses dispersion machine under the condition of 500 ~ 700 turns, disperse to mix and get final product for 10 ~ 20 minutes in scuffing of cylinder bore.
In aforementioned emulsion binding agent, described liquid resin emulsion is made up of by weight percentage following composition of raw materials: 264 stablizers 0.3%, PVA24881%, liquid resin 60%, 908 emulsifying agents 3%, water 35.7%.
Further, the preparation method of described liquid resin emulsion is: liquid resin is put into airtight scuffing of cylinder bore, close scuffing of cylinder bore, start agitator with 60 revs/min of stirrings, heater, the temperature of liquid resin in cylinder is allowed to appreciate 90 DEG C gradually, open vacuum simultaneously, water is added in another scuffing of cylinder bore, emulsifying agent and stablizer heat temperature raising, when temperature rises to 90 DEG C, by water, emulsifying agent and stablizer join in first scuffing of cylinder bore at short notice, mix 40 minutes, open high speed dispersor under the speed of 1000-1500 rev/min, emulsify at a high speed 10-20 minute.
Further, the preparation method of aforementioned emulsion binding agent is: the ACRYLIC EMULSION mixed is put into one with spiral stirrer scuffing of cylinder bore, under the condition of 85 revs/min, slowly add the liquid resin emulsion made, measure viscosity, regulate with water and reach 8500cp and get final product discharging, packaging.
Present invention also offers the application of aforementioned emulsion binding agent in food product pack.
Beneficial effect of the present invention is:
1, the present invention is through a large amount of experimental studies, draw the formula of above-mentioned emulsion tackiness agent, its key is crylic acid ester mixture emulsion, owing to being optimized blending ingredients and blending ratio, the emulsion binding agent excellent performance obtained, shows: 1) cohesive strength is large, open hour are long, be applicable to craft and the production line balance of food package box, can ensure that, at the end of the whole operation of per pass, the binding property of glue is still best.2) for BOPP, the stickup of PET film shows excellent bonding, the material that can reach paper and plastic film is completely destroyed.3) because emulsion binding agent is aqueous binder, abnormal convenient when being coated with, and easily clean, rinse with water, avoid adding of solvent.
The emulsification of the liquid resin in the formula of 2, emulsion binding agent of the present invention, owing to have employed high temperature Phase inversion emulsification technique, be easy to the conversion to water-based emulsion of the oleoresin that just completes, after making water-based emulsion, with whole emulsion system mix abnormal convenient, through centrifugal test, do not have demulsifying phenomenon to occur, meet the requirements completely.
