Wax solvent for steel polishing workpieces and preparation method thereof

Abstract

The invention relates to a wax solvent for steel polishing workpieces. One liter of wax solvent is prepared from the following raw materials in parts by weight: 50-70g of sodium hydroxide, 150-160g ofmonoethanolamine, 20-50g of sodium tripolyphosphate, 5-15g of EDTA disodium, 180-240g of composite surfactant and the balance of water, and one liter of wax solvent further is prepared from 160-180gof hydrolytic agent, wherein the hydrolytic agent is vegetable oil acid, the surfactant is sodium alcohol ether sulphate, nonyl phenol polyoxyethylene ether and fatty acid methyl ester ethoxylate. A preparation method comprises the following steps of adding part of water into a stirring kettle, heating to 60-70 DEG C; adding the sodium hydroxide, monoethanolamine, sodium tripolyphosphate, EDTA disodium and surfactant in sequence; adding water till a desired volume and stirring uniformly. The wax solvent can remove 97% or more wax, can remove wax rapidly, is available for 150 times, reduces production cost remarkably, and brings a great market competitiveness advantage for the enterprise.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to wax-removing water for iron and steel polishing workpieces and a preparation method thereof. Background technique [0002] It has excellent physical and chemical properties and excellent surface treatment performance, and is widely used. In order to improve its performance and surface finish, it will undergo surface polishing treatment, but after polishing, the wax residue remaining on the bus surface must be removed. deal with. [0003] Wax scale is mainly composed of paraffin wax, fatty acid, rosin soap, metal oxides and some inorganic solid polishing particles such as: corundum, silicon carbide, high alumina porcelain, etc. The solid particles are mainly distributed uniformly in the polishing wax system in the form of powder. In addition, there are some grinding cloth remnants, polished metal matrix powder and its oxides. The wax scale and the workpiece ...

Problems solved by technology

[0006] With the development of domestic enterprise technology, the ordinary wax removal water in the market can basically meet its production requirements, but due to the defects of its components, content and preparation methods, there are still slow wax removal speeds, short service cycles, and harmful effects on the substrate. The problem of slight corrosion and discoloration, the components are not environmentally friendly, and there is also a large pollution to the water environment
