Abstract

The invention discloses a metal surface coating and a preparation process thereof. The metal surface coating comprises component A and component B; the component A is made with, by weight, 35-45 partsof hydroxy acrylic resin, 10-20 parts of pentaerythritol, 4-10 parts of ammonium polyphosphate, 3-5 parts of melamine, 8-12 parts of vacuum glass beads, 3-7 parts of siloxane coupling agent, 4-8 parts of m-phenylenediamine, 5-15 parts of nano titania, and 10-16 parts of xylene / butyl acetate mixture; the component B is made with, by weight, 100 parts of biuret; the ratio of the components is strictly controlled; the traditional metal surface coating manufacturing formulas are optimized; the produced metal surface coating has more stable performance; open preservation time may be extended to 12hours; waste of the metal surface coating can be effectively decreased; resources are saved; the environment is protected; aseptic packaging is utilized, and subpackaging requires attention on disinfection of bottlenecks of packaging bottles; a stepless variable frequency disperser is utilized to perform dispersing, so that dispersing effect is better.

Description

technical field [0001] The invention belongs to the technical field of metal surface protection, and more specifically relates to a metal surface coating and a preparation process thereof. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed. In metal surface protection, the protective coating plays a very important role. The application number is CN201210091836.8, which discloses a metal protective coating. The metal protective coating is obtained by uniformly mixing a raw material mixture containing water-soluble Silicate, silica filler, accelerator, water-soluble film-forming resin, vinyl silane coupling agent and water; said accelerator is an ...
