preparation example Construction

[0021] The preparation process of modified rapeseed oil is: mix methanol, tetrabutyl titanate and rapeseed oil, react at 15-55°C for 3-5 hours, after the reaction is completed, distill off the remaining methanol under reduced pressure to obtain modified Compared with the modified rapeseed oil, the modified rapeseed oil has greatly improved the oxidation stability, extreme pressure and anti-wear properties.

[0022] The non-ferrous metal preservative uses benzotriazole, which has a melting point of 98.5°C, a boiling point of 204°C, and a pH value of 5.0-6.0.

[0023] Alkanolamides are selected as non-ionic surfactants. The pH value of alkanolamides is 9.0-11.0, and the appearance is a light yellow clear liquid. It is stable in acid and alkali, has strong wetting and emulsifying power, and can improve foaming. Power, detergency, hard water resistance, can be used as detergent, wetting agent, emulsifier.

[0024] The anionic surfactant is sodium lauryl sulfate, and the density o...

Embodiment 1

[0034] Example 1: In parts by mass, 3.5 parts of alkanolamide and 3.5 parts of sodium lauryl sulfate were sequentially added to 65 parts of modified rapeseed oil, and ultrasonically dispersed at 58°C for 1.5 hours to obtain solution A; In terms of parts by mass, 4 parts of benzotriazole, 3 parts of sodium benzoate, 0.8 parts of nano-silver, and 1.0 parts of nano-silica were added to solution A in sequence, stirred at 56°C for 35 minutes, and then 4.5 parts by mass of Methyl silicone oil, mixed evenly to obtain non-ferrous metal wire cutting paste.

[0035] Dilute the non-ferrous metal wire-cutting paste prepared in Example 1 with distilled water according to a mass ratio of 1:55 to prepare a wire-cutting fluid, which was measured by GB-T 3142-1982 Lubricant Bearing Capacity Determination Method (four-ball method). The maximum non-seizing load value PB of the obtained wire cutting fluid was 92 kg, and the sintering load value PD was 110 kg.

Embodiment 2

[0037] In parts by mass, 2.5 parts of alkanolamide and 3.0 parts of sodium lauryl sulfate were sequentially added to 55 parts of modified rapeseed oil, and ultrasonically dispersed at 56° C. for 1.5 h to obtain solution A; in parts by mass, Add 3.5 parts of benzotriazole, 3.5 parts of sodium benzoate, 0.6 parts of nano-silver, and 0.8 parts of nano-silica to solution A in sequence, stir at 60°C for 35 minutes, and then add 2.5 parts by mass of methyl silicone oil, Mix evenly to obtain non-ferrous metal wire cutting paste.

[0038] Dilute the non-ferrous metal wire-cutting paste prepared in Example 2 with distilled water according to a mass ratio of 1:58, and prepare a wire-cutting fluid, which is measured by GB-T 3142-1982 lubricant bearing capacity test method (four-ball method). The maximum non-seizing load value PB of the obtained wire cutting fluid was 89 kg, and the sintering load value PD was 115 kg.

Abstract

The invention provides non-ferrous metal wire cutting paste. The non-ferrous metal wire cutting paste is prepared from the following raw materials in parts by mass: 50 to 75 parts of modified rapeseedoil, 3 to 8 part of a non-ferrous metal preservative, 2 to 6 parts of a de-foaming agent, 2 to 5 parts of a non-ionic surfactant, 2 to 5 parts of an anionic surfactant, 2 to 5 parts of an antirust agent, 0.5 to 1.5 parts of nano-silver and 0.6 to 2.0 parts of nano silicon dioxide. The invention further provides a preparation method of the non-ferrous metal wire cutting paste; the preparation method comprises the following steps: adding the non-ionic surfactant and the anionic surfactant into the modified rapeseed oil in sequence and carrying out ultrasonic dispersion to obtain a solution A; adding the non-ferrous metal preservative, the antirust agent, the nano-silver and the nano silicon dioxide into the solution A in sequence; stirring for 20 to 40 min at 55 to 65 DEG C; then adding thede-foaming agent and uniformly mixing to obtain the non-ferrous metal wire cutting paste. The non-ferrous metal wire cutting paste provided by the invention has good low-temperature flowability, viscosity-temperature property and thermal stability, and is convenient to transport.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a non-ferrous metal wire cutting paste and a preparation method thereof. Background technique [0002] Cutting fluid is an important supporting material for metal cutting. The purpose of using metal cutting fluid is to reduce the cutting force and the friction between the tool and the workpiece, and take away the heat generated in the cutting area in time to reduce the cutting temperature, reduce tool wear, and improve Tool durability, thereby improving production efficiency, improving the surface roughness of the workpiece, ensuring the machining accuracy of the workpiece, and achieving the best economic effect. [0003] However, wire cutting fluid is mainly used in the market at present, and the processed products are basically based on ferrous metals, and there is no special wire cutting paste for processing non-ferrous metals such as copper and aluminum.
