問題は少なくなってきている。Foamed materials of polyolefin resins such as polyethylene are important as materials for electrical wires because their dielectric constant increases when foamed. However, if a foaming agent is simply blended into the resin, decomposition products resulting from foaming may adhere to the die during processing, impairing the appearance of the coating, and even adversely affecting the electrical properties. In addition, when electric wires are colored with organic pigments to identify them, some of the heat-degraded pigments during processing adhere to the tiles and appear as stains on the surface of the wires over time. Sometimes the appearance was poor. To solve the appearance defects of electric wires caused by these processes, we use a variety of inorganic substances, such as clay, clay, kaolin, glue, bentonite,
It has been proposed to incorporate talc and other substances into the resin, and in cases where no blowing agent is included, adding a numerical coefficient of inorganic substances to the pigment has been shown to be effective, but in systems containing blowing agents, the most effective Even effective silica powder has a 50% resistance to blowing agents.
-100% amount addition was required. A blowing agent composition containing 10 θ parts of azodicarbonamide and 25 to 200 parts of silica powder is sold as a so-called non-great-out type blowing agent by Faisons, Uniroyal, etc. The various problems caused by this are becoming fewer and fewer.

により得られる。By the way, when manufacturing foam insulated wires, it is rare that a foaming agent is added directly to the entire resin, and it is common to color the wires to identify them, and usually pigments and foaming agents are added together or individually. It is used as a masterbatch which is a 10- to 20-fold concentrate. This blowing agent masterbatch is generally prepared by kneading a blowing agent with a polyolefin resin or optionally wax at a temperature below the decomposition temperature of the blowing agent, or by kneading a blowing agent with a polyolefin resin or, if necessary, in powder form. After that, it is obtained by passing it through an extruder.

Due to the thickening and thixotropic properties of the 7-liquor powder, problems such as poor dispersion and distribution occurred, and a uniform composition could not be obtained, such as clogging of the extrusion-like wire gauze. Even if the fluidity was improved by changing the composition of the masterbatch, for example by increasing the proportion of polyolefin wax, a sufficient effect could not be obtained.

That is, the present invention provides a foamable resin composition comprising silica powder, azodicarbonamide, wax, polyolefin resin, and optionally a pigment, in which at least the silica powder is surface-treated with a titanate coupling agent. This is a resin composition for a foamed insulated wire, which is characterized by the following:
