Description
Technical Field
The invention relates to the field, in particular to a high-temperature sterilization resistant aluminum screw cap water-based adhesive coating and a preparation method thereof.
Background
Gaskets of aluminum spiral covers are generally manufactured in a physical foaming mode for many years, so that the gaskets are easy to deform at high temperature to damage the sealing performance, and are not suitable for packaging products such as coffee and the like which need high-temperature sterilization or have higher requirement on internal pressure. The problems can be avoided by adopting the molding cap production equipment to drip the high polymer material into the aluminum screw cap and then pressing the aluminum screw cap into the bottle cap by special equipment, and the aluminum screw cap is widely applied to high-temperature sterilization packaging. At present, the adhesive coating of the aluminum screw cap for high-temperature sterilization is mainly coated on aluminum by solvent type epoxy coating and is adhered with special high-molecular sealing material at a certain temperature and pressure, the sealing material for high-temperature sterilization is generally of a polypropylene type, and a common coating system is difficult to adhere with the polypropylene material.
Most of the existing solvent-type epoxy coatings contain bisphenol A, bisphenol A is an important organic chemical raw material, and important derivatives of phenol and acetone are mainly used for producing various high polymer materials such as polycarbonate, epoxy resin, polysulfone resin, polyphenyl ether resin and the like. The national standards for food safety in GB4806.10 and GB9685 in our country prohibit the use of resins and additives containing bisphenol a in packaging materials for infant food, in france and in the state of california in the united states, the use of materials containing bisphenol a as packaging materials for food and beverages, and in the european union reach regulations (chemical registration, evaluation, approval, restriction) list bisphenol a as a substance of high interest because of its reproductive toxicity, but bisphenol a is no longer suitable for packaging food-contact products, particularly food products requiring high-temperature sterilization, due to its toxic and heat-releasing properties.
