Description

Manufacturing method of conductive rubber roller for textile machinery

In the present invention, when manufacturing rubber rollers used in various textile machines such as rolling machines, coating machines, dryers, tenters, and the like, electricity can flow through the rubber material forming the outer surface of the rollers, thereby preventing static electricity generated by friction with the fabric. It is to be able to discharge naturally.

As is well known, various textile machines use rollers coated with rubber on their surfaces for smooth transfer of the fabric. As the rubber and the fabric are rubbed, static electricity is generated in the rubber roller.

However, the rubber of the existing rubber roller is the material itself can not flow electricity, so the electricity generated by the friction with the fiber is not discharged as it is static electricity that stays in the rubber roller or fabric as it is, the static electricity damages the fabric workers.

In other words, if static electricity stays on the fabric, dust or foreign matter sticks well, resulting in deterioration of the product quality due to deterioration and contamination, and when the worker's body touches the rubber roller or fabric, the static electricity is discharged through the worker's body. Workers are shocked and shocked during work, and even worse when they are distracted or burned.

The present invention devised in view of the above problems makes the rubber itself conductive during the manufacture of the rubber roller for textile machinery, so that the static electricity generated by the friction with the fabric can be discharged immediately and naturally. It aims to prevent the deterioration of merchandise.

Looking at the manufacturing method of the conductive rubber roller according to the present invention in detail as follows.

1st process

Synthetic rubber NBR M / B {Nitrile-butadiene rubber}, the main material for making rubber of rubber rollers, is prepared.N-32 {Nipol Acrylonitrile butadiene Rubber, grade No. 32)} carbon HAF (Carbon Black, grade No 330), rubber reinforcement, and DOP {Di Octyl phthalate), a plasticizer for PVC (polyvinyl chloride), are added to NBR M / B Rubber).

2nd process

NND M / B (nitral rubber) prepared in step 1 is used as a rubber reinforcing agent and an accelerating adjuvant: ZND {us more used as ZNO and called "zinc oxide". , ZND (Zinc oxide) is added to about 3.7% by weight of the NBR M / S (nitral rubber).

3rd process

ST / A (Stearic Acid), a softener, is added to 0.5-0.6% of the N.B.R M / B (nitral rubber) increase and stirring is continued.

4th process

The antioxidant D {chemical name (Reaction product of diphenylamine and acetone)} was stirred by adding 0.5 to 0.6% of the NBR M / B (nitral rubber) weight, but the antioxidant D (Reaction product of diphenylamine and acetone) was added to NBR. When used for (Nitral rubber), it is effective in preventing heat fatigue and preventing bending and burning.

5th process

In order to improve heat resistance, hardness and transparency, 4.3% of the weight of N.B.R M / B (nitral rubber) is added to P.V.C (vinyl chloride) and the stirring is continued.

6th process

The antistatic agent S.N is mixed with about 2.8-2.9% of the weight of N.B.R M / B (nitral rubber) and then stirred continuously.

7th process

Group accelerators for DM {N.R, S.B.R, N.B.R, C.R, etc. as an accelerator for quick ripening are mentioned. Add C12H11N2S2 (Dibenzothiazyldisulfide Benzothiazolyidisulfide)} and CZ {C12 H11 N2 C2 (Cyclohexyl-benzothiazolysulfenamide) with the addition of the accelerators DM (Dibenzothiazyldisulfide Benzothiazolyzo-Zhenxylbenzozoxybenzolbenzoic) Disturb the ratio of 0.85% of NBR M / B (Nitral Rubber) weight. There is 2: 1. The reason for this is that the point of solidification varies depending on the temperature of the rubber.

8th process

Sulfur (S), a rubber vulcanizing agent, is mixed and stirred at about 1.2 to 1.3% of the weight of N.B.R M / B (nitral rubber).

9th process

Conductive rubber material is completed by mixing Coumarone (Indene resin) as 1.4% of the weight of N.B.R M / B (Nitral rubber) and continuing stirring.

10th process

In the process of manufacturing a conductive rubber roller with a conductive rubber material, after applying an adhesive to the surface of the roller made of iron, apply the conductive rubber material to the surface of the steel roller, wrap the rolled tape on the surface and put it in a pressure kiln for 10 hours. After aging, the conductive rubber roller is completed by polishing after aging.

The conductive rubber roller produced in this process is conductive due to the components of the antistatic agent S.N and the accelerator DM (Dibenzothiazyldisulfide Benzothiazolyidisulfide) and CZ (Cyclohexyl-benzothiazolysulfenamide N-cyclohexyl-2benzothiazolysulfenamide) included in the manufacture of the conductive rubber material. In other words, the electrostatic rubber roller is mounted on the textile machine so that the static electricity generated by the friction with the fabric can flow on the conductive rubber roller, so the static electricity is not discharged through the main body of the textile machine.

If the earth machine is buried in the ground or the earth wire is connected to the steel shaft of the conductive rubber roller, it is discharged on the earth machine.

Therefore, the worker can perform the work comfortably without worrying about static electricity.

As described above, the present invention provides the electroconductive rubber rollers used in various textile machines, so that the static electricity generated during the work is discharged immediately, so that the worker can work with confidence, thus improving the work efficiency and It is an excellent invention that can solve the problems related to static electricity generated in textile machinery such as to improve the quality at a glance.
