Abstract

The invention relates to a low-surface treatment rusty rust inhibiting primer and a preparation method thereof. The low-surface treatment rusty rust inhibiting primer comprises a component A and a component B; The component A comprises the following raw materials in parts by weight: 5-50 parts of epoxy resin, 5-50 parts of a filler, 1-10 parts of a rust-converting agent, and 1-50 parts of an anti-rust pigment; and the component B comprises the following raw materials in parts by weight: 30-80 parts of a curing agent, 1-10 parts of a promoter, and 1-15 parts of a silane coupling agent. The low-surface treatment rusty rust inhibiting primer has good adhesion and excellent physical machinery, corrosion and rust protection as well as low-surface treatment performance, the construction performance is good, the low-surface treatment rusty rust inhibiting primer can be taken as a low-surface treatment primer by cooperating with a conventional protection paint, and can be individually used as a functional rusty primer.

Description

technical field [0001] This patent relates to the field of fine chemicals, in particular to a low surface treatment rust-bearing primer and a preparation method thereof. Background technique [0002] The most convenient and economical means of anticorrosion of steel substrates is to choose organic coatings for protection, and the effective service life of coatings must depend on good surface treatment in order to give full play to the anticorrosion performance of coatings. In reality, due to the limitations of the coating construction environment and conditions, it is often difficult to carry out thorough surface treatment according to the rust removal standard. Usually treated substrates still have varying degrees of rust and are often in a highly humid state. The direct coating of ordinary coatings on the surface of this substrate often fails to obtain the expected anti-corrosion effect. Therefore, there is a need for a high-performance low-treatment surface coating that...
