方法として例えば次の方法が採用される。即ち、

粒子と水とを同時に容器内よりも低圧の雰囲気下
に放出することにより発泡粒子を得る。 After kneading, the particles are granulated to obtain polyolefin resin particles containing an inorganic filler, and the particles can be pre-foamed to obtain expanded polyolefin resin particles (so-called pre-expanded particles), for example, as follows. method will be adopted. That is,
After optionally crosslinking the particles, the particles, a volatile blowing agent (e.g., dichlorodifluoromethane), and water are placed in a closed container, and the particles and the blowing agent are dispersed in the water within the container. After heating the particles to a temperature higher than the softening temperature to impregnate the particles with a blowing agent, the pressure inside the container is maintained at a pressure higher than the vapor pressure of the blowing agent, and the pressure below the water surface in the container is Expanded particles are obtained by opening one end and simultaneously releasing the particles and water into an atmosphere at a lower pressure than the inside of the container.

し、加熱発泡させる。しかして型通りの成型体が
得られる。 In order to perform molding using the expanded beads, for example, the expanded beads are aged at a predetermined temperature (usually room temperature) and under normal pressure, and then the expanded beads are aged at a predetermined temperature (usually room temperature) and under a predetermined pressure. inorganic gas (e.g. air)
The foamed particles are aged under pressure to apply increased pressure inside the particles, and then the foamed particles are filled into a mold and heated and foamed. In this way, a molded body conforming to the mold can be obtained.
空隙率が５〜40％であるような多数の空隙２を

のような粒子内圧で成型すれば粒子３同志の融着
の不充分な部分が生じ、それによつて粒子３間に
空隙２が形成されるものである。 In order to form a large number of voids 2 with a porosity of 5 to 40%, it is desirable that the internal pressure of the particles be 0 to 3 Kg/cm 2 (G) immediately before filling the mold. If molding is carried out under such particle internal pressure, there will be areas where the particles 3 are insufficiently fused together, thereby forming voids 2 between the particles 3.
上記の如く構成される壁材１は多数の空隙２を
有しているので吸音性が有り、従つて吸音材とし

熱性を有しており従つて断熱材としても使用でき
る。本考案において空隙率５〜40％としたのは、
５％未満では吸音効果が発揮されず、また40％を
越えると強度が弱くなる上、断熱性能の低下をき
たすからである。 Since the wall material 1 constructed as described above has a large number of voids 2, it has sound-absorbing properties and can therefore be used as a sound-absorbing material.However, since it is a synthetic resin foam molding, it has heat-insulating properties. It can also be used as a material. In this invention, the porosity was set at 5 to 40% because
This is because if it is less than 5%, the sound absorption effect will not be exhibited, and if it exceeds 40%, the strength will be weakened and the insulation performance will deteriorate.
更にこの壁材１は基材樹脂に無機充填剤を配合
しているので、１）硬くて圧縮強度が大きい（圧
縮強度2.5Kg／cm2以上）、２）燃えにくい、３）収
縮が起こらず寸法安定性が良い、という優れた物
性を有するものである。 Furthermore, since this wall material 1 contains an inorganic filler in the base resin, it is 1) hard and has high compressive strength (compressive strength of 2.5Kg/cm2 or more ), 2) is flammable, and 3) does not shrink. It has excellent physical properties such as good dimensional stability.

が付き易い。 When the wall material 1 of the present invention is attached to the exterior wall of a house, it functions as a heat insulating material. Figure 2 shows an example of using the wall material 1 of the present invention as a heat insulating material.
A plurality of walls are attached at right angles at predetermined intervals, and the wall material 1 is attached to the base plate 5 by, for example, nailing. Further, a metal lath material 6 is stretched over the surface of this wall material 1, and finally, mortar 7 is applied to finish it. The mortar 7 is applied to the surface of the wall material 1 through the mesh of the metal lath material 6. At this time, the mortar 7 enters into the many voids 2 on the surface of the wall material 1 as shown in FIG. The anchoring effect is exerted, and the mortar 7 strongly bites onto the surface of the wall material 1 and is firmly bonded. Therefore, there is no risk of the mortar 7 peeling off. Further, although mortar is generally difficult to adhere to heat insulating materials made of synthetic resin foam, mortar easily adheres to the wall material 1 of the present invention since the base resin contains an inorganic filler.
上記構成において壁材１は発泡体の有する断熱

FIG. 4 shows an example of using the wall material 1 of the present invention as a sound absorbing material, in which a plurality of rims 9 are attached to a column 8 at right angles and at predetermined intervals.
The wall material 1 is attached to this rim 9 by, for example, nailing. Furthermore, a surface material 10 such as plywood or vinyl chloride sheet is fixed to the surface of this wall material 1.
上記構成において壁材１はその表面及び内部に
多数の空隙２を有するので、この空隙によつて音
が吸収され、以て吸音材として作用する。 In the above structure, the wall material 1 has a large number of voids 2 on its surface and inside thereof, so that sound is absorbed by the voids, thereby acting as a sound absorbing material.

断熱作用を発揮することも可能である。 The wall material 1 of the present invention can also function as a sound absorbing material and a heat insulating material at the same time. For example, although the main purpose of the structure shown in FIG. 4 is sound absorption, this is not necessarily the only purpose, and it is also possible to have a heat insulating effect at the same time.
