For example, the enamel glaze technologies disclosed in patents CN 102219383B, CN 102517582B and CN 105565669B are all made by the method. This conventional enameling technique has several disadvantages: firstly, the porcelain enameling tool is easy to wear after collision, exposes the substrate, rusts, even rusts holes after a long time, and influences the service life of the enameling tool; secondly, the sintering temperature of the enamel glaze material can often reach 800 ℃ or even more than 1000 ℃, and the energy consumption is very high; thirdly, in the process of processing the enamel, a sand blasting process is needed to process the metal substrate, the environment is polluted, and a plurality of processes such as coating of a primer and a surface glaze are often needed, so that the process flow is complex.
Patent CN 104403382B discloses a water-based high-temperature resistant enamel coating, which is prepared by mixing silica sol, alumina sol, potassium tartrate, titanate and other materials, reduces baking temperature, can achieve the same effect as traditional enamel, but still performs sand blasting treatment on a substrate. Patent CN109294296B discloses a water-based transparent enamel coating technology, which is prepared by mixing materials such as water-based enamel resin (glass fiber reinforced plastic resin), water-based silicon emulsion, silica sol and the like, and has high coating hardness and reduced baking temperature, but the coating contains a small amount of solvent, and has poor coating flexibility and low temperature resistance.
