Problems solved by technology

[0002] Lubricants are often added during the forging process to reduce die wear. In the prior art, graphite lubricants and mineral oil oil-based lubricants are generally used, but the poor lubricating properties of these two types of lubricants lead to a short service life of the die. Processing 5000- 8,000 product molds were damaged, resulting in a short service life of the mold, and graphite lubricants and mineral oil oil-based lubricants tend to leave residues in the mold at high temperatures, which are extremely difficult to remove

Embodiment 1

[0025] The weight ratio of the water-soluble forging lubricant composition in this embodiment is: 0.4 parts of thickener; 0.1 part of fluoride; 2 parts of film-forming aid; 0.5 part of solid lubricant; for water. Among them, the thickener is a mixture of sodium carboxymethyl cellulose and polyacrylamide, the mass ratio of sodium carboxymethyl cellulose and polyacrylamide is 2:1, the fluoride is sodium fluoride, and the film-forming aid is polyacrylamide. Ethylene glycol, the solid lubricant is borax, and the dispersant is sodium hexametaphosphate.

[0026] The preparation method of the water-soluble forging lubricant composition in this embodiment includes the following steps: under normal temperature and pressure, add thickener, fluoride, solid lubricant, and dispersant to the reaction kettle and stir for 20 minutes, then The film-forming aid was added into the reactor and stirred for 2 hours to obtain a water-soluble lubricant composition for forging.

Embodiment 2

[0029] The weight ratio of the water-soluble forging lubricant composition in this embodiment is: 1.2 parts of thickener; 0.5 parts of fluoride; 6 parts of film-forming aid; 2 parts of solid lubricant; for water. Among them, the thickener is a mixture of sodium carboxymethyl cellulose and polyacrylamide, the mass ratio of sodium carboxymethyl cellulose and polyacrylamide is 2:1, the fluoride is sodium fluoroborate, and the film-forming aid is polyacrylamide. Ethylene glycol, the solid lubricant is sodium humate, and the dispersant is sodium polyacrylate.

[0030] The preparation method of the water-soluble forging lubricant composition in this example is exactly the same as that in Example 1.

[0031] The mold using the water-soluble forging lubricant in this embodiment can process 10,000-16,000 products without damage, and the qualified rate of products is increased by 6%.

Embodiment 3

[0033] The weight ratio of the water-soluble forging lubricant composition in this embodiment is: 0.8 parts of thickener; 0.3 parts of fluoride; 4 parts of coalescence aid; 1.5 parts of solid lubricant; for water. Among them, the thickener is a mixture of sodium carboxymethyl cellulose and polyacrylamide, the mass ratio of sodium carboxymethyl cellulose and polyacrylamide is 2:1, the fluoride is sodium fluorosilicate, and the film-forming aid is Polyethylene glycol, solid lubricant is boric acid, dispersant is sodium hexametaphosphate.

[0034] The preparation method of the water-soluble forging lubricant composition in this example is exactly the same as that in Example 1.

[0035] The mold using the water-soluble forging lubricant in this embodiment can process 14,000-20,000 products without damage, and the qualified rate of products is increased by 9%.

Abstract

The invention discloses a water-soluble lubricant composition for forging. A solvent of the water-soluble lubricant composition for forging is water. The water-soluble lubricant composition for forging comprises the following components in parts by weight: 0.4-1.2 parts of a thickening agent, 0.1-0.5 part of fluoride, 2-6 parts of an coalescing agent, 0.5-2 parts of a solid lubricant and 0.5-1.5 parts of a dispersing agent, wherein the thickening agent a mixture of one or two of sodium carboxymethylcellulose or polyacrylamide; the coalescing agent is ethylene glycol; the solid lubricant is a mixture of one or more of boric acid, borax or sodium humate; and the dispersing agent is a mixture of one or two of sodium hexametaphosphate or sodium polyacrylate. When the water-soluble lubricant composition for forging is used, residues which are difficult to remove cannot remain in a die, the lubricating property is excellent, and thus, the service life of the die using the water-soluble lubricant composition for forging is prolonged so that even if more than 10,000 products are processed by the die, the die is not damaged; the yield is increased by 6% or above; and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a water-soluble forging lubricant composition. Background technique [0002] Lubricants are often added during the forging process to reduce die wear. In the prior art, graphite lubricants and mineral oil oil-based lubricants are generally used, but the poor lubricating properties of these two types of lubricants lead to a short service life of the die. Processing 5000- 8,000 product molds were damaged, resulting in a short service life of the mold, and graphite lubricants and mineral oil oil-based lubricants tend to leave residues in the mold at high temperatures, which are extremely difficult to remove. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-soluble forging lubricant composition with good lubricating properties, which can be added during the forging process to effectively prolong the service life...
