Barium-free antirust grease with thixotropy after dilution and preparation method of antirust grease

Abstract

The invention discloses barium-free antirust grease with thixotropy after dilution. The barium-free antirust grease is characterized by comprising the following raw materials in parts by weight: 13-16 parts of beewax, 10-14 parts of spermaceti wax, 36-41 parts of vaseline, 12-15 parts of burning kerosene, 10-13 parts of 50# machine oil, 3-5 parts of attapulgite, 3-4 parts of asphalt, 2-4 parts of precipitated silicon dioxide, 6-8 parts of petroleum sodium sulfonate, 2-3 parts of high-density polyethylene powder, 2-2.5 parts of sorbitan monooleate and 2.5-4 parts of a protective agent. The precipitated silicon dioxide and other thixotropic agents are added into the formula, the phenomenon that waste is caused because the product is easy to flow when being diluted to be used can be avoided, the addition of the protective agent is matched, a firm protective film can be formed on the metal surface, rust caused by erosion of water and oxygen is avoided, and the barium-free antirust grease has the antibacterial, anticorrosive and ultraviolet radiation-resistant effects. Moreover, the antirust grease disclosed by the invention has barium-free and environment-friendly effects, is wide in application range and is suitable for sealing or machining metal parts, and can be used through multiple ways.

Description

technical field [0001] The invention relates to the field of antirust liquid, in particular to a barium-free antirust grease with thixotropy after dilution and a preparation method thereof. Background technique [0002] In order to protect the metal from the corrosion of the corrosive medium in the environment, anti-rust grease is usually used in engineering construction to isolate the metal surface from the corrosive medium. Using anti-rust grease as a temporary protection is an ideal and effective anti-corrosion method, which has the advantages of good effect, convenient use, low cost, easy operation and easy removal. However, most barium-containing slow-release and corrosion-inhibiting ingredients have serious harm to the environment and human body, and developed countries are gradually replacing them, and European and American countries have strictly restricted their use. [0003] The invention adopts a dilutable formula, which can be used after being diluted with 10 ti...
