Description
Technical field
The present invention relates to a kind of aqueous aluminum foil heat-sealing emulsion compositions sealed suitable for aluminium foil with non-polar substrate, category
In technical field of aqueous paint.
Background technology
Packaging heat-seal adhesive is mainly used in the fields such as daily chemical products, packaging for foodstuff and liquid soft package.Due to being filled in product
When packaging heat-sealing at be easiest to leak, and the damage of packaging bag largely also occurs in heat-sealing portion when actually used
Point, therefore select the suitable heat-sealable material with higher thermal sealing strength to be particularly important.With the frequency of food-safety problem
Hair, people increasingly pay attention to the security of food and packaging material for food, and the material for being used for liquid food packing in European Union is more next
More tend to non-polar substrate, therefore non-polar substrate PP is more and more used in food packaging applications, but non-polar substrate by
The characteristics of its material itself, the problem of there is more difficult heat-sealing；It is existing to be used in non-polar substrate PP and Al foil substrate heat-sealing aspect
Material be all solvent based product, this has the pollution of the product for introducing solvent and environment.Solvent based product is in itself containing a large amount of
Harmful organic solvent, also needs to the organic solvents such as ethyl acetate or toluene and is diluted, in production process when using
With substantial amounts of organic volatile, health, environment are caused harm, shipping storage has certain disaster hidden-trouble.Therefore,
Develop a kind of novel environment-friendly type and just seem urgent and particularly necessary with the product that non-polar substrate is sealed applied to aluminium foil.
The content of the invention
It is an object of the invention to efficiently solve what existing solvent-borne type non-polar substrate and Al foil substrate heat-seal adhesive were present
The problem of food and environmental pollution.A kind of aqueous aluminum foil high suitable for aluminium foil and non-polar substrate PP heat seal strengths is provided to seal
Use emulsion compositions.
The present invention is achieved by the following technical solutions：
A kind of aqueous aluminum foil heat-sealing emulsion compositions, it is made up of the following component of percentage：
Preferably, the acrylic emulsion is methyl methacrylate and butyl methacrylate copolymer breast
Liquid.
Preferably, the solid content of methyl methacrylate and the butyl methacrylate copolymer emulsion is 45
~55%.
Preferably, the molecular weight of the methyl methacrylate and butyl methacrylate copolymer is 3~15
Ten thousand, TG are 50~70 DEG C.
Preferably, the solid of the EAA emulsions (ethylene-acrylic acid copolymer emulsion) contains for 30~45%.
Preferably, the molecular weight of the EAA is that 3~150,000, TG is 50~70 DEG C.
Preferably, the cosolvent is NMP (1-METHYLPYRROLIDONE) or DBE (DBE is nylon acid dimethyl ester)
Preferably, the PU116 or PU118 of this preferred Dutch tal fibre of the inorganic adhesion promoter.It is main into
It is divided into nano silicon.
Invention herein has simultaneously using the acrylic emulsion attachment fastness excellent to Al foil substrate and EAA to PP and aluminium foil
There is excellent caking property, further attachment fastness of the anchor coat on aluminium foil in the presence of inorganic adhesion promoter, heat
Intensity increases during envelope, and production is simple, efficiency high, is a kind of environment-friendly type heat-sealing glue composition.
Compared with existing traditional non-polar substrate PP and Al foil substrate heat salable composition, the present invention has following beneficial effect
Really：
1st, aqueous product composition, fills up the application field blank；
2nd, safety and environmental protection is pollution-free；
3rd, heat seal strength is controllable, meets various heat seal strength requirements.
