Abstract

The invention discloses a raw silk rust-proof cutting fluid which comprises the following raw materials by weight: 0.1 to 0.2 part of diaveridine sodium, 0.1 to 0.2 part of polyurethane, 0.6 to 1 part of ascorbic acid, 3 to 4 parts of sodium silicate, 4 to 6 parts of calcium stearate (soap), 0.1 to 0.3 part of propanediol phenyl ether, 3 to 4 parts of polylactic acid, 16 to 20 parts of dimethyl sulfoxide, 4 to 5 parts of raw silk, 21 to 30 parts of triethanolamine borate, 0.7 to 2 parts of span 80, and 200 to 300 parts of deionized water. A fibroin lubricating liquid (an intermediate product of the raw silk rust-proof cutting fluid) is mixed with triethanolamine borate and a rust inhibitor (another intermediate product of the raw silk rust-proof cutting fluid) to obtain a liquid mixture; the liquid mixture is modified with polylactic acid. Therefore, the fracture strength and wettability of a blend membrane can be improved; a lubricating film layer formed on the friction metal surface can be more stable; the extreme pressure anti-wear property and reaction activity are improved effectively.

Description

A kind of raw silk rust preventive cutting fluid

Technical field

The present invention relates generally to cutting fluid field, particularly relates to a kind of raw silk rust preventive cutting fluid.

Background technology

Cutting fluid is that one is used in metal cutting, the mill course of processing, be used for the industrial type fluid of Cooling and Lubricator cutter and workpiece, cutting fluid is formed through the cooperation of science compound by multiple super strong functional auxiliary agent, possesses good cooling performance, lubricity, rustless property, oil removing cleaning function, anti-corrosion function, easily dilutable feature simultaneously.Overcome the easily difficult dilution in smelly, winter in summer of traditional soap base emulsion, rust-proof effect difference defect, lathe paint is also had no adverse effects, be applicable to ferrous metal cutting and mill processing, belong to leading current abrasive product.

For reducing metal because of the loss brought of wearing and tearing in the course of processing, the performance requriements of each manufacturing enterprise to metal working fluid is more and more higher; Simultaneously; due to the attention of Environmental protection; propose the requirement such as cleaner production, energy-saving and emission-reduction; impel metal working fluid towards environmental protection, energy-conservation, efficient future development. fully synthetic cutting fluid has the advantages such as clean environment firendly, resource are wide, easy preparation, is the prior development direction of metal working fluid from now on.

Summary of the invention

The object of the invention is just to provide a kind of raw silk rust preventive cutting fluid.

The present invention is achieved by the following technical solutions:

A kind of raw silk rust preventive cutting fluid, it is made up of the raw material of following weight parts:

TMP sodium 0.1-0.2, polyurethane(s) 0.1-0.2, xitix 0.6-1, water glass 3-4, stearic acid calcium soap 4-6, propylene glycol phenylate 0.1-0.3, poly(lactic acid) 3-4, dimethyl sulfoxide (DMSO) 16-20, raw silk 4-5, Triethanolamine borate 21-30, sorbester p17 0.7-2, deionized water 200-300.

A preparation method for raw silk rust preventive cutting fluid, comprises the following steps:

(1) get water glass, xitix, the mixing of TMP sodium, add propylene glycol phenylate after stirring, insulated and stirred 10-15 minute at 50-60 DEG C, obtains rust-preventive agent;

(2) 60-70% getting above-mentioned Triethanolamine borate weight mixes with polyurethane(s), and insulated and stirred 3-5 minute at 90-95 DEG C, obtains esterification material;

(3) poly(lactic acid) is joined in dimethyl sulfoxide (DMSO), obtain PLA solution;

(4) above-mentioned raw silk is joined in the sodium carbonate solution of its weight 90-100 0.4-0.6wt% doubly, heat-insulation soaking 60-80 minute at 98-100 DEG C, filter, dry, wear into fine powder, mix with sorbester p17, add the 60-70% of above-mentioned deionized water weight, stir, obtain fibroin lubricating fluid;

(5) get the 3-5% of above-mentioned rust protection liquid weight, mix with PLA solution, fibroin lubricating fluid and remaining Triethanolamine borate, magnetic stirring apparatus stirs 6-7 minute, obtains extreme pressure lubricating liquid;

(6) mixed with remaining esterification material by above-mentioned extreme pressure lubricating liquid, be heated to 85-90 DEG C, 80-100 rev/min of dispersed with stirring 20-30 minute, add each raw material of residue, 600-1000 rev/min of dispersed with stirring 30-40 minute, obtains described cutting fluid.

Advantage of the present invention is:

Fibroin lubricating fluid of the present invention take silk as major ingredient, nontoxic pollution-free, oilness is high, wherein Triethanolamine borate has good oilness and extreme pressure anti-wear, and this rust-preventive agent take water glass as major ingredient, easily in metallic surface deposition, propylene glycol phenylate effectively can improve film-forming properties, isolated air, improves rust-proof effect;

Triethanolamine borate, rust-preventive agent are mixed with silk fibroin solution, and adopt polylactic acid modified, breaking tenacity and the wettability of blend film can be improved, more stable lubricant film layer can be generated on the surface at frictional metal, effectively raise extreme pressure anti-wear and reactive behavior.
