Antirust temperature-resistant primer

Abstract

The invention discloses an antirust temperature-resistant primer. The primer comprises the following raw materials in parts: 20-30 parts of ethanol, 20-25 parts of xylene, 15-20 parts of dimethylformamide, 15-20 parts of ethyl acetate, 10-15 parts of ethylene-propylene latex solution, 15-20 parts of pure acrylic latex solution, 5-15 parts of diatom mud, 5-8 parts of dibutyl phthalate, 5-10 parts of ammonium persulfate, 5-8 parts of polyvinyl alcohol resin, 15-18 parts of phosphoric acid, 5-10 parts of hydrochloric acid, 5-12 parts of ferrous oxide, 12-15 parts of copper oxide, 5-10 parts of silica, 5-10 parts of iron hydroxide, 5-10 parts of bentonite, 5-10 parts of activated clay, 3-5 parts of montmorillonite, 5-10 parts of heavy calcium carbonate and 50-80 parts of deionized water. The antirust temperature-resistant primer has the advantages of rust-removal performance, antirust performance, high-temperature resistance, water resistance, convenience in application and salt water resistance, the coating does not fall off or generate bubbles, the coating film does not crack and does not fall off or protrude, and no swelling or color bleeding is generated.

Description

technical field [0001] The invention relates to the technical field of a rust-removing primer, in particular to a rust-removing and temperature-resistant primer. Background technique [0002] At present, most of the antirust primers in the prior art use organic solvents as diluents, which inevitably contain undesirable gases and toxicity held by organic solvents, are easy to burn when exposed to fire, and have adverse effects on the environment and laborers. , and because the paint film after painting and construction contains organic solvents, it is selective to the topcoat used with it, which often causes wrinkling, blistering, and peeling of the paint surface, which seriously damages the apparent quality of the painted metal components. Reduce the service life and economy of the product. Contents of the invention [0003] The purpose of the present invention is to provide a kind of derusting heat-resistant primer in order to overcome the shortcoming of above-mentioned ...
