AI Technical Summary

Problems solved by technology

Due to the smooth surface of copper-plated steel wire, the requirements for mortar viscosity and silicon carbide concentration are relatively high, and waste pollution is serious after use.
In addition, the copper-plated steel wire has poor wear resistance, severe wear during cutting, and relatively poor ability to carry abrasive materials. During cutting, the free blade is easy to slip with the

Embodiment 1

[0026] An aramid core wire free blade cutting wire, the preparation method of which is as follows:

[0027] ① Core wire purification treatment: Twisting high-strength aramid III fibers with a diameter of about 8 microns into aramid fibers with a diameter of about 0.1 mm

[0028] The surface of the thread is degreased with absolute ethanol, the treated aramid thread is dried, and then the surface is treated with ethanol solution of KH-550 coupling agent with a mass concentration of 3% for 2 minutes, washed with absolute ethanol, and dried. spare.

[0029] ②Preparation of coating composite agent: Ultrasonic treatment of the filler in acetone for 20 minutes (frequency 18 kHz) and drying, surface treatment with ethanol solution of KH-550 coupling agent with a mass concentration of 3% for 120 minutes, and filtering out with anhydrous After washing with ethanol, dry at 50°C, then add the filler to the phenolic resin accounting for 36% of the volume of the slurry and mix for 45-60 m...

Embodiment 2

[0033] In this example, the difference from Example 1 is that the filler used is composed of diamond micropowder, copper powder, silicon carbide micropowder and aramid fiber chopped strands. The prepared slurry contains 2% volume content of diamond powder with a particle size of 0.5 microns, 8% volume content of copper powder with a diameter of 2 microns, 10% volume content of silicon carbide micropowder with a diameter of 5 microns, and 7% volume content of 5 microns in diameter. Aramid chopped strands 1 mm in length.

[0034] The dicing wire produced had a diameter of 0.12 mm and a resin bond coating of about 10 microns.

Embodiment 3

[0036] In this embodiment, the difference from Example 1 is: replace the phenolic resin accounting for 36% of the slurry volume with polyimide resin accounting for 39.5% of the slurry volume (do not need to add NL phenolic resin when using polyimide resin resin curing agent), replace acetone solvent with dimethylacetamide. The temperature used for heating and curing the curing tube in step ③ is 375°C.

[0037]The dicing wire produced had a diameter of 0.12 mm and a resin bond coating of about 10 microns.

Abstract

The invention relates to a free edge material cutting line with an aramid core wire. The cutting line comprises an aramid core wire and a resin binder coating coated on the core wire, wherein the aramid core wire is aramid III. The cutting line is characterized in that the aramid yarn, instead of the steel wire, is used as a core wire and has the advantages of high strength, good toughness, high wear resistance, light weight, long service life and the like, also has good sand-carrying property when used for cutting hard and brittle materials and can obviously improve the cutting efficiency and the utilization ratio of the processed materials and lower the production cost.

Description

technical field [0001] The invention belongs to the technical field of cutting materials, and specifically relates to a free blade cutting wire with aramid fiber as the core wire and coated with a resin binder coating on the surface and a preparation method thereof. This type of cutting wire is used for monocrystalline silicon, Cutting processing of polycrystalline silicon, jade, sapphire, glass, quartz and other high-hardness, high-brittleness and high-wear-resistance materials, with the characteristics of high efficiency, long life and high finish. Background technique [0002] Hard and brittle materials include gems, glass, stone, silicon crystals, quartz crystals, ceramics, hard alloys, etc. Hard and brittle materials are mostly semiconductors or non-conductors, with high hardness, high brittleness, high wear resistance, high resistivity and other properties. Hard and brittle materials are widely used in sound, light, electromagnetic, machinery and chemical industries b...
