Problems solved by technology

[0003] With more and more types of domestic beverages, the requirements for the tolerance of the tank body are getting higher and higher, such as coconut milk and other protein beverages require coatings to have a certain sulfur resistance, such as acidic beverages such as apple cider vinegar, which is the first choice for the coating on the inner wall of the tank There are higher requirements for high-temperature acid boiling resistance, and soda drinks such as cola are filled with a large amount of CO 2 The acidity is very high, and the BPA-Free packaging container in the prior art needs to be improved in terms of acid resistance, compactne

Abstract

The invention provides a coating for the inner surface of an aluminium food packaging container and a manufacturing method thereof and relates to the technical field of production of snap lids. The coating is characterized by comprising the following components by weight percent: 13-30 percent of modified acrylic resin, 33-60 percent of polyester resin, 5-15 percent of amino resin, 1.5-5 percent of gas-phase silicon dioxide, 0.5-5 percent of a leveling foam killer and 30-60 percent of a diluent. The coating does not contain BPA; being an organic solvent coating, the coating is provided with a freezing-resistant performance. Therefore, the coating has the characteristics of digestion resistance, aging resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of easy-open lid production, in particular to an inner surface coating of an aluminum food packaging container and a manufacturing method thereof. Background technique [0002] At present, due to the problem of BPA residues in the coating made of epoxy resin, BPA has been proved by research that it may cause various diseases (such as: precocious puberty, heart disease, diabetes, abnormal liver function), and many domestic and foreign laws have been issued to ban BPA. Laws and regulations (such as: on January 4, 2013, the Swedish Code of Statutes (SFS) published the regulation SFS 2012:991, prohibiting children under 3 years old from containing BPA in food packaging coatings and coatings; Nevada, USA passed Prohibition of BPA laws and regulations Bill No.354, the regulations stipulate that since January 1, 2014, no one shall manufacture, sell or distribute in Nevada any bottle or cup with bisphenol A intentio...
