Embodiment Construction

[0013] A kind of cast iron antirust agent, used raw material and weight percentage are as follows:

[0014] Potassium benzoate 12-35%

[0015] Alkyl fatty acid ester 10 ~ 20 %

[0016] Dibasic acid ester 0.5 ~ 5 %

[0017] Potassium hydroxide 15-30%

[0018] Alkyl borate 20 ~ 30%

[0019] Soda ash 4 ~ 11%.

[0020] The production method of the cast iron antirust agent is carried out as follows: add alkyl boric acid ester, dibasic acid ester, and alkyl fatty acid ester into the reaction kettle, heat to 100-125°C and stir, and cool down to Keep the temperature at 90~100°C, then add potassium benzoate, potassium hydroxide, and soda ash until all the components dissolve in each other, cool down to below 60°C, and pack after testing and filtering. The test item indicators are as follows:

Abstract

The invention discloses a cast iron antirust agent. The cast iron antirust agent comprises 12-35wt% of potassium benzoate, 10-20wt% of alkyl fatty acid ester, 0.5-5wt% of diester, 15-30wt% of potassium hydroxide, 20-30wt% of alkyl borate and 4-11wt% of soda ash. A production method of the cast iron antirust agent comprises the following steps: adding alkyl borate, diester and alkyl fatty acid ester into a reaction kettle, heating to 100-125DEG C, stirring until mutual dissolution, cooling to 90-100DEG C, maintaining the temperature unchanged, adding potassium benzoate, potassium hydroxide and soda ash, cooling to below 60DEG C after mutual dissolution of all components, detecting, filtering, and packaging.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a cast iron antirust agent with low cost, stable performance and long-lasting antirust effect and a production method. Background technique [0002] In the manufacturing equipment industry, it is essential to clean and rust-proof the surface of cast iron workpieces. It is required that the cleaning agent can effectively clean off the oil stains and dust on the cast iron workpiece, and at the same time form an anti-rust layer on the surface of the cast iron workpiece to prevent the cast iron workpiece from rusting. At present, most of the water-based anti-rust agents are imported by famous foreign companies such as BASF, PARKERIZING, BMW, IDEMITSUKOSAN, etc., not only the price is high, but also the cost of product processing is increased, and the anti-rust is not durable enough. Contents of the invention [0003] The purpose of the present invention is to solve the above-menti...
