TECHNICAL FIELD The present invention relates to a composite material that is excellent in flexibility, soundproofing properties, and workability, and is a composite material that can be used in many fields such as sound insulating material, sound absorbing material, electromagnetic shielding material, and vibration isolating material.

とが要求される。この他人斌使用の用途向けには価格。Various types of sound insulating materials are known to prevent external noise from entering or radiating to the outside, and sound absorbing materials that reduce sound reflection. It can be processed into a sheet and laid on the floors and walls of automobiles, railway vehicles, and buildings, adhered to uneven or curved surfaces, and used for OA.
For use as a composite agent for equipment case materials, steel plates, and nonwoven fabrics, it is required to be as thin a sheet as possible, have a high areal density, have good flexibility, and have good moldability. . The price is low for this purpose.

In order to improve the sound insulation effect, it is important to make the area density as low as possible, and for this purpose, it is important to fill as much high-density filler as possible. However, inorganic particles generally have a poor affinity for binders, and a large amount of filling is required.

That is, the affinity of the binder and the filler is related to each other, and an inappropriate combination will result in poor mechanical strength of the product, occurrence of out-of-play phenomenon during molding, and deterioration of the surface finish of the product.

It is disclosed in the No. 064 publication. Although this oxide is said to have excellent adhesive properties with vinyl chloride, it is difficult to peel off from the roll surface during molding, the gelation time is long, and the mechanical properties such as bending of the resulting sheet are not sufficient. I can not say. Further, Japanese Patent Application Laid-open No. 78742/1983 discloses a means of using metal powder on which an oxide film or a phosphoric acid film has been formed. In general, lead and copper have poor affinity with organic materials.
Cracks and cuts easily occur due to bending stress.

である。The inorganic particle filler used in the present invention preferably has a large bulk specific gravity from the viewpoint of areal density, particularly for sound insulation and sound absorption properties, and preferably has electrical conductivity from the viewpoint of electromagnetic shielding property. Specifically, metals such as lead, copper, iron, and nickel, fine particles of their oxides, composite powders of lead plated with copper, carbon, graphite powders, or composite powder particles of these metals plated with copper are applicable. These may be used not only as a single component but also as multiple components. In particular, to improve sound insulation properties, it is preferable to use metal particles such as lead or copper, or iron oxide as a main component. In order to exhibit an electromagnetic shielding effect, it is preferable to use conductive particles. Lead has a large ratio 7R and is advantageous in preventing black corrosion. Copper-plated composite powder is
This is preferable because it improves conductivity. The inorganic particles may be in any of the shapes of spheres, scales, and fibers, and it is effective to use fine particles with a mesh size of 100, preferably 200 mesh.

On the other hand, it is not preferable to use an alkali or alkaline earth metal oxide as a filler component because it reduces moldability, so it is desirable to limit the amount to about 10 wt% or less. When iron oxide is used as inorganic particles, iron concentrate slag produced as a by-product in the non-ferrous smelting process and converter slab produced in the iron manufacturing process are economical and compatible with binders.

Approximately 0.02 to 5 parts by weight of the soap metal may be added per 100 parts by weight of the inorganic particles and dried. When adding it, it is best to dilute it with petroleum extract, aromatic solvent, mineral turpentine, etc., and then spray or soak it. There is no need for surface treatment of the second filler, silica, which has only a small effect when added after mixing or into the binder.
