DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. Prior to the description of the configuration of the filter, a method for producing a composite molding material will be described first with reference to FIGS.

FIG. 1 shows a production process of a composite molding raw material. First, in a first step S1, waste paper is crushed using a crusher for about 0.5 to 5 minutes.
Pulverize to mm square to facilitate mixing. On the other hand, in a second step S2 in FIG. 1, PP (polypropylene) as an example of a synthetic resin is pulverized using a pulverizer. This pulverization is performed for the purpose of facilitating mixing and ensuring uniform physical properties of the raw materials. As this PP, used waste material (industrial waste) PP can be used.
E (polyethylene) may be used, or both PP and PE may be used. Either used or unused PP and PE may be used.

Next, the used paper pulverized in the third step S3 in FIG. 1 and the pulverized PP are put in a tumbler as a mixing device and mixed. Here, the mixing ratio of the used paper and PP is set such that the used paper is 51 wt% or more and the PP is 49 wt% or less.

Next, in a fourth step S4 in FIG. 1, the waste paper and PP mixed in the above-mentioned predetermined ratio are supplied (input) from the hopper of the extruder to the inside of the extruder, and are heated and kneaded. . Here, the heating temperature is adjusted according to the mixing ratio of waste paper and PP, but is set to a temperature higher than approximately 120 ° C.

Next, in a fifth step S5 in FIG. 1, the kneaded material uniformly kneaded by the extruding section of the above-mentioned extruder is extruded, and is stretched into a plate shape using a shaping machine, as shown in FIG. The plate-like molding raw material 11 as described above is formed. When this plate-shaped molding raw material 11 (raw material after kneading) is cut into approximately 0.5 to 5 mm square as shown in FIG. 3 using a cutting device in a sixth step S6 in FIG. A usable composite molding raw material 12 is formed (see the seventh step S7 in FIG. 1).

FIG. 4 shows an air filter provided in the intake system of the engine for purifying the intake air. The air filter 13 includes a filter member 14 (element body) formed by accumulating paper or nonwoven fabric into a bellows shape and a ring shape. Annular support plates 15 and 16 for supporting the filter medium 14 from above and below are provided. The three members 14, 15 and 16 are integrally assembled, housed in a cleaner case (not shown), and supplied to the engine. This is to purify the intake air. Here, the above-mentioned support plates 15 and 16 as support members are formed of a composite molding material 12 in which used paper and PP are kneaded at a predetermined ratio.

As described above, according to the air filter 13 shown in FIG. 4, the support plate 1 of the air filter 13 is formed by using the composite molding raw material 12 in which the used paper and the synthetic resin are kneaded at a predetermined ratio.
Since the layers 5 and 16 are formed, the volume of the molding raw material can be increased and the cost can be reduced as compared with the case where the raw material of the resin alone is used. In addition, there is an effect that inexpensive waste paper, which is generally generated in large quantities and normally disposed of in landfills, can be effectively used and resources can be reused.

Moreover, since the support plates 15 and 16 formed of the composite molding material 12 described above are flammable, the filter medium 14 and the support plates 15 and 16 (that is, the entire air filter 13) must be incinerated at the same time. In addition, the calorie burned during the incineration treatment is smaller than that of the resin alone (approximately 50 to 60% of that of the resin alone), so that the heat consumption required for combustion can be reduced. is there.

In addition, the supporting plates 15 and 16 of the air filter 13 are formed by using the composite molding raw material 12 in which the used paper is kneaded at a ratio of 51% by weight or more and the synthetic resin at a ratio of 49% by weight or less. Can be turned into general combustible waste, and the entire air filter 13 can be treated (disposed) as general combustible waste according to the law stipulated by the Waste Management Law and the like.

FIG. 5 shows another embodiment of the filter.
The air filter 21 shown in FIG. 1 is detachably incorporated in the inside air suction portion of an indoor unit in an air conditioner for home use or factory use. This air filter 21 constitutes a filter frame 24 as a supporting member by integrally extending a support 23 extending vertically and horizontally with respect to a frame body 22 surrounding four circumferences. The screen 25 formed by combining fibers and the like in a predetermined mesh shape is integrally stretched.

Here, the above-mentioned filter frame 24 is formed using a composite molding raw material 12 in which waste paper and PP are kneaded at the above-mentioned predetermined ratio. Thus, even if the filter frame 24 of the air filter 21 of a different model is formed of the composite molding material 12, the filter 24 can be made flammable, and the entire air filter 21 can be incinerated and disposed simultaneously. The same operation and effect as those of the previous embodiment can be obtained.

In the correspondence between the configuration of the present invention and the above-described embodiment, the filter of the present invention corresponds to the air filters 13 and 24 of the embodiment. And the support member corresponds to the support plates 15, 16 and the filter frame 24, and the synthetic resin corresponds to PP (polypropylene). However, the present invention is limited to only the configuration of the above-described embodiment. is not.

For example, PE (polyethylene) can be used as the synthetic resin in addition to PP. Further, the filter of the present invention can be applied to an air filter for a car cooler other than the air filter disclosed in the embodiment and other industrial and ventilating air filters for removing dust and the like in the air.
