Antirusting paint for watercraft

Abstract

The invention discloses antirust paint for ships, which is prepared by epoxy resin, butanol, phosphoric acid, antirust agent, thickening agent, dispersant, film forming agent, basic lead chromate silicate, coal tar pitch, V45 asphalt antirust paint thixotropic agent and water. The antirust paint has the advantages that the antirust paint not only can effectively solve the thixotropic problem of the paint, but also can improve adhesive force of the paint to a steel material greatly, reduce construction processes, and ensure film thickness of the paint, and has stable physical property of the paint film, low toxicity, chemical medium resistance, and strong weather resistance.

Description

Technical field: [0001] The invention relates to an antirust paint. Background technique: [0002] The existing antirust paint has poor adhesion to steel materials, short service life, often cracks or detachment, and has problems such as thixotropy. Invention content: [0003] The object of the present invention is to provide an antirust paint for ships which has high adhesion to iron and steel materials and can effectively solve the problem of thixotropy. [0004] Technical solution of the present invention is: [0005] An antirust paint for ships is characterized in that: it is made of the following raw materials in parts by weight: [0006] 5-8 parts of epoxy resin [0007] 4-8 parts of butanol [0008] Phosphoric acid 2~3 parts [0009] Antirust agent 7~9 parts [0010] Thickener 6~7 parts [0011] Dispersant 40~50 parts [0012] Film-forming agent 7-10 parts [0013] 10-15 parts of basic lead silicate chromate [0014] Coal tar pitch 0~10 parts [0015] V45...
