-1, eventually sticking intensity reaches 308N.m
-1
Bonding principle of the present invention:
Composite soft packaging is that the plastics film with unlike material is bonded into the composite soft packaging film, thereby obtains meet specific requirement, high performance compound package material.Because the diversity of plastics film, requirement is used for the compound tackiness agent must have stronger bonding suitability, and the fundamental component of water-based polyurethane adhesive, the polymkeric substance that is polyol and polyisocyanates just has such performance, can be used for producing the tackiness agent that is fit to multi-purpose excellent property.The polyolefin film material is most widely used composite soft packaging base material, belongs to non-polar material, and its surface free energy is lower, about 29～30mJm
-2Theoretically, if Solid Surface Free Energy is lower than 33mJm
-2, so just can't be attached to present known any tackiness agent.Therefore, be used for film compound polyolefin film, must improve its surface free energy, reach 38～40mNm through surface treatment
-1More than, could obtain satisfied adhesive effect, the surface treatment method of the plastics film that generally adopts both at home and abroad is a corona treatment at present.
Aqueous polyurethane has good wetting ability for all types of plastic film through corona treatment.The viscosity of aqueous polyurethane is generally little, in 100mPa.s, even can be through being low to moderate below the 10mPas, so aqueous polyurethane has good flowability in recombination process.
Hydrogen bond is a kind of Intermolecular Forces of specific type, polyolefin film surface through corona treatment can produce carbonyl and carboxyl, and there are groups such as ammonia ester, urea, ester, ether in the base-material polyurethane molecular of aqueous polyurethane, so tackiness agent and adherend surface can form hydrogen bond widely, improve the bonding strength of tackiness agent.
According to theory of chemical bonds, when cementitious system produces the chemical bond connection, help improving Joint strength, prevent progress of fracture, also be highly resistant to stress concentration, particularly importantly, the formation of interfacial chemistry key is significantly increased to the anti-water and the dielectric corrosion ability of adhesively bonded joint.Under many circumstances, between tackiness agent and the adherend surface chemical reaction can not take place directly, in order to reach the purpose that chemical bond connects, can adopt coupling agent.It is coupling agent that the present invention adopts adipic dihydrazide.The adipic dihydrazide structural formula is:
An end that is dissolved in the adipic dihydrazide molecule in the water-based polyurethane adhesive can react with isocyanate group or other nucleophilic group of remnants in the polyaminoester emulsion, the other end can generate hydrazone with the carbonyl reaction on the polyolefin film, make and form the chemical bond connection between tackiness agent and the substrate surface, thereby bonding strength to tackiness agent, particularly water-fast and anti-medium is significantly increased, and its reaction process can be expressed as follows:
In sum, multiple modified water-based polyurethane adhesive viscosity is less, at the polyolefin surfaces good fluidity; Surface tension is little, and is less in the wetting angle of polyolefin surfaces, and polyolefin surfaces is had the good wet ability; Polyurethane molecular can produce hydrogen bond force widely with the polyolefin surfaces through corona treatment.Therefore, water-based polyurethane adhesive and polyolefin surfaces exist stronger adsorption, and adhesive effect is good.On the other hand,, can produce chemical bonding force, strengthen bonding strength and the water-fast and anti-dielectric corrosion ability of water-based polyurethane adhesive greatly polyolefin surfaces at tackiness agent and polyolefin surfaces by adding the coupling agent adipic dihydrazide.The acting in conjunction of these factors just, it is good bonding that water-based polyurethane adhesive has been formed the polyolefin film surface.
