Aerosol can type metal mold rust inhibitor and manufacturing method thereof

Abstract

The invention discloses an aerosol can type metal mold rust inhibitor with stable thermal property and long rust-proof life, which uses the following raw materials in parts by weight: 40-70 parts of barium petroleum sulfonate, 30-50 parts of zinc naphthenate, 5-10 parts of lanolin magnesium soap, 10-25 parts of rosin, 30-50 parts of N32 machine oil, 80-120 parts of turpentine oil and 550-675 parts of aviation kerosene. The manufacturing method is carried out according to the following steps: a) firstly stirring the measured rosin in the turpentine oil in a stainless steel container, and stirring till being transparent; b) stirring the measured barium petroleum sulfonate and the lanolin magnesium soap in part of the aviation kerosene in another stainless steel container, and stirring till being uniform and translucent; c) adding the remaining aviation kerosene into a reaction kettle, leading the rotational speed to be 60 turns / min, sequentially slowly adding the measured zinc naphthenate, the N32 machine oil and preparations prepared by the steps a) and b) into the reaction kettle, and stirring till being dark brown, uniform and translucent liquid.

Description

Technical field [0001] The invention relates to a metal mold rust inhibitor and a manufacturing method, in particular to an aerosol can type metal mold rust inhibitor with stable thermal performance and long rust prevention period and a manufacturing method. Background technique [0002] Because the mold cavity is relatively complex and its dimensional accuracy is relatively high, if the surface of the working part is rusted, the surface finish and accuracy of the working part of the mold can be changed, which directly endangers the surface quality of the metal or non-metal workpiece formed after the mold is processed. , In severe cases, the mold will be scrapped directly. Therefore, in the machinery and equipment manufacturing industry, most of the metal molds are processed with solvent-based anti-rust oil to prevent rust from the entire mold during the processing and use of various metal molds, especially when the mold is periodically shut down or out of service. Periodic anti...

Problems solved by technology

At present, the antirust treatment of metal molds is mainly by dipping, brushing, spraying, etc., coating the surface of ferrous metal workpieces with solvent-based antirust oil, relying on the formed oil film to prevent the metal from being corroded by the atmosphere, and its antirust performance is generally It is evaluated by damp heat test (GB / T2361), salt spray test (GB / T0081) and weather resistance test (SH / T0083), but the thermal stability of the existing solvent-based antirust oil is poor, which makes the mold The rust period can only last about two months
