Embodiment 1

[0017] Embodiment 1, preparation epoxy resin emulsion

[0018] The mass ratio of the raw materials used in this example is as follows: the mass-number ratio of the mixture of epoxy resin, DPM, ethylene glycol glyceryl ether, ethanol and water is 50:50:8:15.

[0019] Accurately weigh the DPM, put it into a stainless steel reaction kettle, start stirring slowly at room temperature at 300r / min, slowly add the accurately weighed epoxy resin into the stirring DPM liquid, and then gradually increase to 1300r / min in 20min and then in Stir at a high speed to 1800r / min within 45min, and continue stirring for 6h. When the temperature in the kettle reaches 90-100° C., the stirring is stopped to obtain the base material.

[0020] The base material is a water-white transparent liquid (no mechanical impurities), no suspended sediment, and the viscosity of the base material (by rotational viscometer) is 7800-8300cp (23±2°C).

[0021] Add the base material obtained above to ethylene glycol ...

Embodiment 2

[0022] Embodiment 2, preparation epoxy resin emulsion

[0023] The mass ratio of the raw materials used in this example is as follows: the mass-number ratio of the mixture of epoxy resin, DPM, ethylene glycol glyceryl ether, ethanol and water is 40:50:9:18.

[0024] Accurately weigh the DPM, put it into a stainless steel reaction kettle, start stirring slowly at room temperature at 300r / min, slowly add the accurately weighed epoxy resin into the stirring DPM liquid, and then gradually increase to 1300r / min in 20min and then in Stir at a high speed to 1800r / min within 45min, and continue stirring for 6h. When the temperature in the kettle reaches 90-100° C., the stirring is stopped to obtain the base material.

[0025] The base material is a water-white transparent liquid (no mechanical impurities), no suspended sediment, and the viscosity of the base material (measured by rotational viscosity) is 7800-8300cp (23±2°C).

[0026] Add the base material obtained above to ethylene...

Embodiment 3

[0027] Embodiment 3, prepare internal coating

[0028] After accurately weighing the epoxy resin emulsion and the methyl etherified amino resin prepared in Example 1, put them into a stainless steel reaction kettle in turn, start stirring slowly at 300r / min for 10min, gradually increase to 600r / min, then add ethanol and water , then increase to 900r / min, drop polyether modified silicone defoamer (French Baoshi Chemical Co., Ltd., 681F), continue to increase to 1300r / min, shear time 45min, after fully compatible, stop stirring, After standing for 24 hours, the inner coating is obtained, and the properties are shown in Table 1.

[0029] In the paint prepared in this example, the mass ratio of epoxy resin emulsion, methyl etherified amino resin, defoamer, ethanol and water is 70:5:0.2:6:4.

Abstract

The invention discloses an aluminum kettle internal coat and its special coating. The coating is composed of an epoxy resin emulsion, a methanol etherified amino resin, an antifoaming agent, ethanol and water. The epoxy resin emulsion is prepared through the steps of mixing dipropylene glycol mono methyl ether with an epoxy resin, stirring to obtain a base material, adding ethylene glycol diglycidyl ether to the base material to obtain a mixture, emulsifying the mixture under stirring, adding an ethanol and water mixture when the material is a viscous emulsion, and continuously emulsifying to obtain the epoxy resin emulsion. After the internal surface of a kettle is coated with the coating, the precipitation of aluminum ions and trace elements of lead, cadmium and arsenic harmful to the health of human bodies from the inner surface of the kettle can be thoroughly blocked, so a plurality of drinks comprising cold water, hot water, carbonated beverages, white spirits and the like can be contained in the kettle for a long time, the application range of the aluminum kettle is substantially widened, and the safety and quality level of field drinking water of outdoor activities, earthquake relief work and military actions can be effectively guaranteed.

Description

technical field [0001] The invention relates to an inner coating of an aluminum kettle and a special coating thereof, belonging to the technical field of chemical coatings. Background technique [0002] If the inner coating of the aluminum kettle is not properly treated, some aluminum ions and harmful elements such as lead, cadmium, and arsenic will be precipitated during the process of holding beverages, which seriously threatens people's health. World-renowned aluminum kettles, such as SIGG kettles in Switzerland and LAKEN kettles in Spain, have successfully avoided the precipitation of aluminum ions and other harmful elements during the use of aluminum kettles through the development of inner coatings. , greatly improving the hygienic performance of the kettle. The safety of drinking water is a major issue related to the national economy and the people's livelihood, especially if the utensils carrying water are not hygienic, it will cause secondary pollution of water, wh...
