Abstract

The invention discloses a black metal water-based antirust agent. The black metal water-based antirust agent comprises the following raw materials in parts by weight: 7 to 12 parts of ethanol amine, 1to 1.5 parts of dodecyl tribasic acid, 0.5 to 1.5 parts of boric acid, 2 to 3 parts of a settling agent, 0.3 to 0.7 part of a hard water resistant agent, 1 to 2 parts of a corrosion inhibitor, 0.5 to1 part of a defoaming agent, 1 to 1.5 parts of trisodium phosphate, 1 to 3 parts of sodium tripolyphosphate, 2 to 4 parts of sodium hydroxide, 0.3 to 0.9 part of sodium molybdate, 2 to 5 parts of benzotriazole, 0.5 to 1.5 parts of a complexing agent, 2 to 3 parts of zinc oxide, 1 to 3 parts of sodium benzoate and 0.2 to 1 part of dibutyl phthalate. The black metal water-based antirust agent has agood antirust function, also has a certain cleaning effect and is suitable for popularizing.

Description

technical field [0001] The invention relates to the technical field of antirust agents, in particular to a water-based antirust agent for ferrous metals. Background technique [0002] Metal is a material with luster, good electrical conductivity, thermal conductivity and mechanical properties, and a positive temperature coefficient of resistance. Metals are a big family, and there are 86 kinds of metals in the world. Usually people divide metals into ferrous metals and non-ferrous metals according to their characteristics such as color and properties. Ferrous metals mainly refer to iron, manganese, chromium and their alloys, such as steel, pig iron, ferroalloy, cast iron, etc. [0003] Corrosion is one of the main forms of damage to metal products. In order to avoid corrosion and reduce losses, people have adopted various methods. Among them, using antirust agents to protect metal products is one of the most common protection methods at present. The antirust agents in the...
