Abstract

The invention relates to light industry aluminum and iron printing coating, in particular to deep punching stewing-resistant transparent aluminum lid gloss oil which is prepared by following steps: polyester resins is taken as basal materials, right amount of methyl etherified tripolycyanamide and butyl etherified benzoguanamine is taken as a cross linking agent, also right amount of closed type polymeric isocyanate and epoxide resins is taken as an additive in an auxiliary way, an auxiliary agent,is added, right amount of acid catalyst is induced, and reserved carboxyl of the basal materials and a small quantity of hydroxide radical are carried out cross linking solidifying reaction under set temperature and time with activated functional groups of epoxide resin carboxyl, a cross linking resin and the acid catalyst. The invention adopts the maximum basal materials-polyester resins, adopts the butyl etherified benzoguanamine, the closed type polymeric isocyanate and the polyester resins to be matched with the polyester resins to be used and has optimized mixture ratio among the composites, thereby reaching the reasonable cross linking density, reducing the internal stress and enhancing the stretchability resistance, the flexible property and the water and stewing resistant property.

Description

Technical field: [0001] The invention relates to coatings, especially aluminum and iron coatings for light industry printing. Background technique: [0002] With the development of glass bottled foreign wine, beverages and various medicinal wines and health wines in our country, the demand for bottle caps made of aluminum is increasing day by day. At present, there are nearly 200 aluminum bottle cap production plants in my country, with an annual design and production of more than 10 billion bottle caps. According to industry forecasts, the consumption of China's anti-theft bottle caps will grow at an annual rate of 10%. In 2010, the domestic market alone will require about 15 billion anti-theft bottle caps, and a large number of products will be supplied to the international market. In recent years, with the improvement of people's living standards, especially with the improvement of environmental protection laws and the laws and regulations of food, pharmaceutical and oth...
