JPS582350A - Electrically conductive transparent resin - Google Patents

Abstract

PURPOSE:To obtain the titled colorable resin having stable electrical resistance and dry surface, effective for the antistatic treatment, and suitable as the antistatic parts of IC, etc., by compounding titanium oxide etc. to a plastic base. CONSTITUTION:A plastic matrix is compounded with a proper amount of an electrically conductive transparent particles, e.g. granular or acicular particles of titanium oxide having a diameter of 0.1mu and treated at 1,200 deg.C. Addition of 3% titanium oxide gives antistaticity without lowering the transparency of the original resin.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transparent conductive resin that is effective as an antistatic VC.

In general, synthetic resin a has a very high electrical resistance (VC) and has the drawback of being easily charged with static electricity.

Conventionally, a graphite carbon-containing glasstic is known as an antistatic plastic. This rtrr polymeric polymer carbon taglastic base material is mixed at ~28% and is manufactured as an antistatic toolastic with an electrical resistance value of toe ~108 Ω/j. However, although this carbon black plastic has an excellent effect of preventing the generation of static air, it causes 29 pollution due to the carbon falling off. There is a tendency for people to lose weight.

In addition, commercially available antistatic agent-containing plastics are supplemented with Ba fatty acid-based surfactant plastics made by removing glycerin from animal fat [5 to IO%/i]. The surface adsorbs moisture in the atmosphere and exhibits a resistance of 109 to 1011 Ω/1, reducing static electricity. The effect of preventing 4F tortoise is obtained.The transparency is milky white and not perfect, but the layer colorant makes it colorful VC&! It is something that can be built. However, one of the disadvantages of surfactants is that they absorb dirt other than moisture, leaving the surface with a dirty, sticky, and sticky feel, which is why many people dislike it when they are buried in factories. Further, there were drawbacks such as unstable humidity conditions in the atmosphere, such as unstable vc and xv resistance values.

This invention was made to improve the above-mentioned conventional drawbacks, and in particular, the resistance value is stabilized.

The present invention provides a transparent conductive resin that is smooth on surface A, transparent, and colorable. .

Hereinafter, the details will be explained based on the experimental results of this invention.

First, the transparent conductive resin (C, S) of this invention VCx.

By adding appropriate amount of transparent conductive particles to the plastic base material (polymer), Vcxo, whistle, and air resistance can be lowered and Vcxo can be lowered.
The action of C particles is to cause self-discharge, making it an effective material for preventing static electricity.

If you add titanium oxide (
'I'i02) is 0.1μ spherical, acicular particle is 120
It was heated to 8 liters at 0°C, and many discharges occurred on the surface of the tree, and when it was mixed in at 3%, it became transparent enough to absorb light and prevents charging.

The transparent conductive resin manufactured by x';tvc mentioned above has one damping effect, that is, it forcibly charges static electricity, and the time required for the charging filter to be halved using a synchroscope is particularly effective. This is due to the fineness of the particles and the amount of liquid VC.

In general, it is said that the discharge of Ilp air Jl [α is multiplied by the number of conductive particles per unit area n5, excluding the case of static electricity removal equipment v! This is a phenomenon well known as L performance.

The attached Figure 1 is a comparison diagram of the attenuation effect when mixed with the size of the particles and J↑1 area. [Molded transparent conductive resin, molded to 1-thickness by mixing L&J particle aluminum powder as B additive, and molded to 2-thickness by mixing 2-Iso particle aluminum powder as Ca additive It is.

In addition, l OKV forced charging [jru halved JtJJ? This is the ta meeting measured with a synchroscope, and the temperature a at this time is
The temperature was 25°C and the humidity was 50%.

You can make colorful glass sticks.

Therefore, the antistatic effect of this invention is very low.

Widely used for antistatic parts such as transparent conductive resin rxIo, magazines, IO trays, semiconductor-related packaging and storage containers, antistatic bags, medical equipment, precision instruments, automobile interior parts, and all kinds of parts that require dustproofing.
