Description
Technical field
The present invention relates to the adhesive bonding method field of tackiness agent and on-mechanical aspect, be specially a kind of the environment-friendly type water base adhesive and the manufacture method thereof that are applicable to low surface tension overlay film.
Background technology
In packaging industry, some stationery wrapped product is (as medicine box, wine box, food box, paper hand bag etc.) for protection against the tide, antifouling, wear-resisting, folding, false proof, improve glossiness, the reasons such as protection internal layer need overlay film, plastic film material conventional in packing box has polyethylene (PE), polypropylene (PP), polyester (PET) and novel Biaxially oriented polypropylene film (BOPP) (BOPP) etc., these plastics films belong to non-polar polymer, its initial surface tension is quite low, major part is less than 32mN/m, be not suitable for boning, so plastics film will carry out corona treatment, improve its surface tension, with the bonding of applicable tackiness agent, the surface tension of general film reaches more than 38mN/m, just be applicable to adhesive bonds.
Even if but through corona treatment, the surface tension of film still can prolongation in time and disappearing, and the speed disappeared is relevant with storage environment temperature.Generally, after film carries out corona treatment, the capillary shelf-time was at about 2 to 3 months; If containing additive in plastic film, easily separate out and cover film surface, make adhesiveproperties be deteriorated due to low-molecular-weight material, then the surface tension after process disappears faster.
At present, the manufacture craft of the paper article packaging product of overlay film class is generally:
1. in printing house, complete paper product base material printed patterns;
2. in printing house, complete paper product base material be covered with surface treated PP, BOPP film or other types of membranes;
3. complete moulding process in package plant, the paper product of overlay film is made box or packing bag form, there is sealing bonding in this process overlay film face and paper product inner face, i.e. the bonding of paper and film.
Due to the not equal reason of machining location, storage time is there is between 2nd and the 3rd procedure, the film tension value after surface treatment (i.e. dyne value) may be caused to decline, the sealing of film and paper is caused to bond very difficult, if do not have suitable glue bonding that lot of materials will be caused to scrap, waste resource.
Summary of the invention
In order to overcome the defect of prior art, providing the binding agent that a kind of cohesive force is strong, applied widely, the invention discloses a kind of the environment-friendly type water base adhesive and the manufacture method thereof that are applicable to low surface tension overlay film.
The present invention reaches goal of the invention by following technical solution:
Be applicable to an environment-friendly type water base adhesive for low surface tension overlay film, it is characterized in that: comprise following component:
The described environment-friendly type water base adhesive being applicable to low surface tension overlay film, is characterized in that: comprise following component:
The described manufacture method being applicable to the environment-friendly type water base adhesive of low surface tension overlay film, is characterized in that: implement successively as follows:
First water-based polyhutadiene-ammonia ester emulsion is thrown in stainless steel stirring tank together with aqueous acrylic emulsion, open dispersion machine, implement to stir after dispersion machine frequency being adjusted to 20hz ~ 30hz according to the difference of turnout, slowly add water-based moistening flatting agent while stirring, 45min ~ 90min is stirred together after adding moistening flatting agent, then dispersion machine frequency is adjusted to 10hz, slowly add acrylate copolymer emulsion and water-borne wax emulsion, after adding, dispersion machine frequency is adjusted to 20hz ~ 30hz, stir 30min ~ 60min, rotating speed is kept slowly to add Gum Rosin solution stirring 30min ~ 60min, then dispersion machine frequency is adjusted to 10hz, add remaining water, finish the rear difference according to turnout and dispersion machine frequency is adjusted to 20hz ~ 30hz, stir 30min ~ 60min, manufacture is completed after detection physical index is qualified, the frequency-adjustable of the high then dispersion machine of general turnout obtains higher, otherwise the frequency-adjustable of the low then dispersion machine of turnout must be lower.
The leading indicator of water base compound stick when applying is embodied in following 4:
A. bonding strength (tack);
Whether a bonding packing box is torn rotten by bonding base material if being met to tear to observe along limit, scrape the paper substrate be attached on film with nail, if a fritter paper substrate or just can not scrape any more paper substrate and show that the tack of this tackiness agent on film is good can only be torn at every turn at all simultaneously.
B. high thermal resistance;
In the constant temperature oven bonding packing box (at least having placed a day) being put in 60 DEG C, baking is taken out side seam or end mouth after cooling for 48 hours and is not flicked, the packing box of both hands bat does not simultaneously come unstuck, glued membrane is embrittlement not, shows that the resistance toheat of this tackiness agent is no problem.
C. lower temperature resistance;
Bonding packing box (at least having placed a day) is put in refrigerator is anxious to be frozen in room-15 DEG C and take out for freezing 48 hours, treat that clapping packing box with hand after box moisture has been done does not come unstuck, glued membrane is embrittlement not, shows that the resistance to low temperature of this tackiness agent is no problem.
D. the retentivity of bonding strength
The product that three kinds of tackiness agent that all have passed bond above is preserved some samples and checks a packing box every two weeks, both hands are clapped and are not come unstuck, and glued membrane is embrittlement not, the persistency check all no problem use showing that this sealing compound can be relieved half a year.
The present invention is directed to and covered film and the paper wrapper not yet carrying out taking mouth, because objective factor causes the surface energy of film to be unfavorable for bonding situation lower than 35mN/m, develop a kind of tackiness agent, carry out sealing bonding for the packing box for low surface tension film.
Initial bonding strength of the present invention is excellent, good, environmentally friendly to the sticking power of film, and high to the packaging box sticky knotting strength of low dyne paper sealing, ageing-resistant performance is good.
