Modifier for black metal surface matrix and production method thereof

Abstract

The invention discloses a modifier for a black metal surface matrix. The modifier comprises the following raw material components in part by weight: 7 to 9 parts of aminotriacetic acid, 7 to 9 parts of lauric acid, 5 to 7 parts of malic acid, 3 to 5 parts of sorbic acid, 0.3 to 0.5 part of diethylenetriamine and 78 to 90 parts of water. A production method for the modifier comprises the following steps of: putting the water into a reaction kettle, then putting the aminotriacetic acid into the reaction kettle, fully stirring the water and the aminotriacetic acid till full dissolution, putting the lauric acid, the malic acid, the sorbic acid and the like into the reaction kettle respectively, fully stirring the components uniformly and melting the mixture, raising the temperature to be between 60 and 70 DEG C, keeping the temperature constant, reacting and chelating the melt for 1 hour at the constant temperature with stirring, then standing and performing natural complex reaction for 1 hour, finishing chelating when the solution is converted into a clear substance, obtaining a modifier finished product, and discharging, packing and selling the product. The modifier can be used for a long term; and the production method does not need discharge, only needs to continuously add raw agents, does not produce acid mist, acid gas or sour, does not drain waste water, and has no environmental pollution. The modifier enhances black metal facilities and equipment, and high-temperature resistance and oxidation corrosion resistance of products reaches over 2 times; and the modifier enhances the friction impact resistance of the black metal by over 2 times, and has quite considerable economic benefit and wide application.

Description

technical field [0001] The invention relates to the field of ferrous metal surface matrix modification, in particular to a modifier composition for ferrous metal surface matrix modification and a production method thereof. Background technique [0002] So far at home and abroad, 80% of all manufacturing industries such as machinery, units, heavy machinery, trains, automobiles, ships, military tanks, warships, aircraft, guns, hardware, electrical appliances, tools, construction, etc. are made of ferrous metals. Materials, namely cast steel, high and low carbon steel, plain carbon steel, and low alloy steel are used as main parts and parts, and the surface has not been modified. The reason is that there is no such treatment process, so the metal surface matrix has not been modified, resulting in the machinery, units, trains, automobiles, ships, military tanks, warships, aircraft, guns, The main body and parts of hardware, appliances, electrical tools, construction facilities ...

AI Technical Summary

Problems solved by technology

However, there are several major defects in electroless plating: ① cannot modify the surface matrix of ferrous metals

③Electroless plating solutions are toxic substances that increase environmental pollution

④ high cost

⑤ still can not achieve full resistance to oxidation and corrosion of high temperature and low temperature, various solvents, gas, sulfur oxides, etc.

⑥Although the anti-friction and impact steel properties, product quality, and service life have been improved and extended, they have not been adopted due to the first five major defects, so most of the foreign countries have not adopted the chemical plating process

In China, the chemical plating process is basically not used.
