Abstract

The invention discloses a falling-off-preventing metal coating and a preparation method thereof. The falling-off-preventing metal coating comprises raw materials in parts by weight as follows: 10-20 parts of polyether silicate ester, 20-30 parts of gamma-valerolactone, 40-60 parts of 2-ethyl-1,6-hexanediol, 10-50 parts of zinc, 10-20 parts of calcium oxide, 2-5 parts of an anti-rusting agent, 100-120 parts of nano-silica, 50-80 parts of nano-titania, 10-60 parts of thiourea, 20-30 parts of diammonium hydrogen phosphate and 40-50 parts of water. The preparation method of the falling-off-preventing metal coating comprises steps as follows: polyether silicate ester, gamma-valerolactone, 2-ethyl-1,6-hexanediol, zinc, calcium oxide, the anti-rusting agent, thiourea, diammonium hydrogen phosphate and water are mixed uniformly, then the remaining components are added, and a metal surface subjected to deoiling, annealing and borax processing is coated with an obtained solution and is dried and sintered. The coating can be effectively attached to the metal surface, thereby preventing metal from rusting and oxidation.

Description

technical field [0001] The invention relates to an anti-shedding metal coating and a preparation method 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. [0003] The Chinese patent application with the application number CN201410411117.9 discloses a method of arc spraying an aluminum-based corrosion-resistant metal coating on a steel structure. The aluminum-based corrosion-resistant metal coating is an aluminum-nickel composite metal coating. The spraying method It includes the following steps: (1) substrate surface pretreatment; (2) substrate surface spraying metal coating; (3) metal coating sealing treatment. Through the above m...
