Abstract

The invention belongs to the grinding field and particularly discloses a coated grinding wire producing method. A coated grinding wire comprises a base body, adhesion agents and grinding materials. Various kinds of cellosilk are used as the base body. Grinding particles are adhered onto the various kinds of cellosilk so as to enable the cellosilk to have a grinding function and enable a coating grinding tool to switch from a planar state to a linear state. Grinding dust can be removed easily in the utilization process of the coated grinding wire and after the utilization of the coated grinding wire, so that the coated grinding wire is better than emery cloth and sandpaper. Clearance exists between wires, so that heat dissipating effect is good. Ground and polished wires are fluffy, plump and soft and can be used for treating uneven planes.

Description

The production method of coated grinding silk

Technical field

The invention belongs to field of milling, be specially the production method of coated grinding silk.

Background technology

Coated abrasive tool is that abrasive material is sticked on various matrixes with bonding agent, due to the difference of various matrixes, and has formed various coated abrasive tool, as emery cloth, sand paper, abrasive band etc., be widely used in every field, especially, when hand lapping, use in a large number emery cloth, sand paper.In some special grindings, because the matrix of coated abrasive tool has flexibility, and use abrasive band in a large number.

Coated abrasive tool is comprised of three parts, and the one, matrix, the 2nd, abrasive material, the 3rd, binding agent.The manufacture method of coated abrasive tool is: matrix is processed, is coated with primer, is planted sand, coated glue, dry.

Current coated abrasive tool, the shape of the matrix using is mainly plane, so coated abrasive tool mostly occurs with the shape of plane, non-coated abrasive tool, be mostly three-dimensional, if use the matrix of coated abrasive tool instead linear state by flat state, in grinding, can play a lot of useful effects.

Fiber is a kind of wire article.Fiber has fluffy, plentiful, soft style, and has the feel of wool, usually as cloth, fabric.Various fibers are used widely, and the production technology of various fibers is constantly perfect, and price is also more and more cheap, for example: its purposes such as superfine fibre, shin-gosen, new shin-gosen, high-shrinkage fibre, carbon fiber are utilized by extensive exploitation.

If on the fiber of having produced, adhere to abrasive material, make filament, there is the function of grinding and polishing, and bending property is better, can replace sand paper, emery cloth, to make up the various shortcomings of sand paper, emery cloth.

Summary of the invention

On various filaments, abrasive particle in bonding, makes filament, has had the function of grinding.

Technology path of the present invention

, comprise matrix, bonding agent, abrasive material.

Described matrix is various filaments.

Described bonding agent is primer layer and multiple glue-line, and the thickness of primer layer is according to the grain size number decision of filametntary thickness and abrasive material, and the different purposes of the product that the thickness of multiple glue-line is produced by the present invention determine.

The production method of coated grinding and polishing silk, is undertaken by following technique: each raw material of filament evenly mixes in proportion, after being dried, through screw rod, melt extrude, by spinneret ejection spinning, coiling, obtain spun filament, balance is by stretching, be coated with primer, static is planted abrasive particle, redrying, coated glue, three times dry, solidifies flexing, bundling, warehouse-in.

Beneficial effect of the present invention

1. coated grinding silk is easy to get rid of abrasive dust after using neutralization to use, and is better than coated abrasive;

2. coated grinding silk abrasive article, light decorations are effective;

3. owing to having space between silk and silk, so good heat dissipation effect;

4. the matrix of coated grinding silk can be selected different filaments according to different purposes, makes the various product of price and purposes;

5. because grinding and polishing silk has fluffy, plentiful, soft character, can process rough surface.

Accompanying drawing explanation

Fig. 1 is technological process schematic block diagram of the present invention.

The specific embodiment

Below in conjunction with embodiment, the present invention is described further.

Example, a kind of production method of coated grinding silk.

A production method for coated grinding silk, is undertaken by following flow process: each raw material of manufacturing single evenly mixes in proportion, after being dried, through screw rod, melt extrude, by spinneret ejection spinning, coiling, obtain spun filament, balance is by stretching, be coated with primer, static is planted abrasive particle, redrying, coated glue, three times dry, solidifies flexing, bundling, warehouse-in.

Concrete steps are as follows:

The first step: PFT bottle chips and PET silk material are being mixed, be dried to 140 degree, vacuum condition at 130 degree Celsius;

Second step: keep 140 degree temperature Celsius, add 0.1% calcium stearate under normal pressure, mix;

The 3rd step: mixture melt extrudes through screw rod, obtains spun filament through spinneret ejection spinning, coiling;

The 4th step: balance is by stretching;

The melt temperature melt extruding is 280 degree Celsius; melt viscosity is 0.55dl/g; spinning ring blowing temperature is 15 degree Celsius; wind speed is 1m/s; cabinet temperature is 30 degree Celsius, and winding speed is 1137m/min, and spinneret draft ratio is 145; the temperature stretching is 28 degree Celsius, and relaxation heat setting temperature is 60 degree Celsius;

The 5th step: coat primer on the polyster fibre silk stretching;

The 6th step: electrostatic sand-planting, sand grains is selected brown corundum No. W1, redrying, baking temperature is at 95 degree;

The 7th step: coated glue, three times are dry, and baking temperature is at 105 degree;

The 8th step: solidify, solidification temperature is at 115 degree, and the time is 24 hours;

The 9th step: flexing rolling.

In the 7th step and the 9th step process, the processing of spraying, to increase the flexibility of coated grinding silk.

Claims
