Description
Technical field
The present invention relates to a kind of aqueous polyurethane and aquosity polyurethane adhesive and application thereof, relate in particular to a kind of soft packaging with the aqueous polyurethane of low-cost high-solid-content and low-viscosity and aquosity polyurethane adhesive and preparation method thereof.
Background technology
Packing is the key areas that tackiness agent and adhesive bonding technique are answered, and tackiness agent and glue technology play a part in packaging industry emphatically, even has determined the quality of Package Quality.Along with the development of foodstuffs industry, soft packaging is more and more paid attention to by people.The quality of soft packaging is closely related with used tackiness agent again, and polyurethane adhesive is because its excellent performance, can be resisted cold, the flexible packing material of oil resistant, drug-resistant, various performances such as transparent, wear-resisting, occupy an important position aspect the agent so stick with glue in soft packaging.Polyurethane adhesive is divided into two-pack and single component.Monocomponent polyurethane adhesive generally is made up of isocyanate terminated based prepolymers or its closure, by with contain active hydrogen component or airborne reaction of moisture and solidify and to produce bounding force; Bi-component polyurethane adhesive is made up of terminal hydroxy group component (the polyurethane-type terminal hydroxy group product that polyester or polyether glycol or they form with vulcabond, chainextender) and isocyanate terminated basic component.When terminal hydroxy group is polyester polyol, higher thermotolerance, bonding strength, oil-proofness and oxidation-resistance are arranged, but hydrolysis less stable: when the terminal hydroxy group component is polyether glycol, snappiness, lower temperature resistance and water tolerance are preferably arranged, but intensity and ageing resistance are relatively poor.
At present polyurethane adhesive is based on solvent-borne type, and used organic solvent is inflammable, explosive, volatile, smell is big, poisonous, pollutes during use and brings public hazards.Along with promulgating a decree, a lot of countries, department limit the use of volatile organic compounds (VOC), develop nuisanceless tackiness agent, comprise that water-based polyurethane adhesive, no-solvent type polyurethane adhesive and hot melt type polyurethane tackiness agent replace deleterious solvent borne polyurethane tackiness agent to become the main direction of current polyurethane adhesive development.
Aqueous polyurethane is dispersion medium with water, have nontoxic, safe, free from environmental pollution, do not fire, advantages such as bonding strength, hardness and sticking power preferably, meet green industrial expansion requirement, be widely used in fields such as tackiness agent, coating, hide finishes at present, obtained attention both domestic and external.
Soft packaging use polyurethane adhesive, the bonding strength height, heat sealability that keeps urethane except need well, at aqueous polyurethane is the characteristics of dispersion medium and water-based polyurethane adhesive coating process with water, also need propose some special requirements, as require water-based polyurethane adhesive low viscosity, high solids content, low cost; Requirement has good water tolerance and levelling property etc.
U.S. Pat P6,235,384 have proposed a kind of preparation method who is applicable to flexible dry type soft packaging with the water-based polyurethane adhesive of high solids content, with polyoxytrimethylene dibasic alcohol and hexanodioic acid/hexylene glycol/composite raw materials of synthetic polyester diol such as m-phthalic acid and (tetramethyl-benzene dimethylene) vulcabond, the dimethylol propionic acid that hydrophilic radical is arranged, react base polyurethane prepolymer for use as, add in the water that contains ammonia and disperse, dispersion adding quadrol and thanomin are crosslinked, before multiple film, add aziridine and make outside cross-linking agent, adopt be in, external crosslinking and usefulness reach service requirements.But because the surface tension of water reaches 7.3 * 10
-4N/cm, and the surface tension of film is (3～4) * 10
-4N/cm, because the big clung body surface of the liquid fine wetted surface tension force of ability that surface tension is little, so do not add processing, the levelling property of water-based polyurethane adhesive on film is generally relatively poor, and the quality of levelling property directly influences the apparent mass of soft packaging, and these do not propose in this patent; One of main raw material of this patent use-isocyanic ester is (tetramethyl-benzene dimethylene) vulcabond in addition, and its price is tolylene diisocyanate or diphenylmethanediisocyanate about two times, causes the cost of water-based polyurethane adhesive higher.
