Description

【発明の詳細な説明】 本発明はカーボンブラックを含有する塩化ビニル重合体
組成物の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a vinyl chloride polymer composition containing carbon black.

近年、帯電防止を求められるエレクトロニクス関連機材

トであるため、透明性が求められる等の特殊な用途を除
いて最も多く用いられている。In recent years, there has been increasing interest in conductive plastics for use in electronics-related equipment and electromagnetic shielding materials that require antistatic properties. Furthermore, carbon black is the most commonly used conductive material, except for special applications where transparency is required, because it is less expensive than other materials.

かも比較的安価であるＫもかかわらず、現状ではその使
用はきわめて限定されている。However, materials made of vinyl chloride polymer as a conductive plastic with carbon blanks dispersed therein cannot be used for purposes other than soft materials containing a large amount of plasticizer.
Although K is suitable for precision molding due to its dimensional stability of molded products and is relatively inexpensive, its use is currently extremely limited.

−からも敬遠されることの多い作業である。The reasons for this are, firstly, that the decomposition temperature of vinyl chloride polymer is low, so it is impossible to mold it in the low melt viscosity region like other polymers, and secondly, it is necessary to obtain conductivity. In order to achieve this, it is generally necessary to blend 8 to 15 percent by weight or more of carbon black, and in order to uniformly disperse it in the polymer, K requires a considerable amount of mixing time, resulting in heat generation and decomposition of the polymer. There are some things that cannot be overlooked. Also, as can be said for any polymer, blending with a polymer is extremely difficult for carbon black, especially carbon black for conductive materials, whose bulk specific gravity is extremely small and individual particles are around several hundred angstroms. , and the working environment.”
- This is a task that is often avoided by people.

After mixing, it is also possible to polymerize to obtain a vinyl chloride polymer containing carbon blank, but if the vinyl chloride polymer containing carbon black has a high degree of polymerization, the above-mentioned stage of vinyl chloride polymer However, the range of molding conditions cannot be said to be wide due to the large amount of heat generated by crosstalk, and if the degree of polymerization is low, the mechanical strength of the molded product is even lower. There are restrictions on usage.

Therefore, there is no need for processing steps such as pre-mixing to uniformly disperse carbon black, and there is no decomposition of the vinyl chloride polymer due to long-term cross-wiring, etc., and the carbon has excellent processability and is suitable for extrusion molding, injection molding, etc. A black-containing vinyl chloride polymer composition was obtained, leading to the present invention. That is, the present invention combines a carbon black-containing vinyl chloride polymer obtained by adding carbon black to a vinyl chloride monomer and adding a small amount of a vinyl chloride polymer obtained by an emulsion polymerization method having a higher degree of polymerization than the vinyl chloride polymer. This is a method for producing a vinyl chloride polymer composition, which comprises mixing.
