Description

The present invention relates to laminates and air intake devices.

Since a combustor of an engine or the like requires air, an intake device is used in front of the combustor to introduce air into the combustor.
The air intake device has an intake port (air intake) that takes in outside air, an air duct that guides the air taken in from the intake port to an air cleaner, an air cleaner, and an air duct that guides the air that has passed through the air cleaner to a combustor. .

It is known that static electricity is generated in an air intake system due to the operation of a vehicle including the air intake system, friction of air passing through an air duct, etc., and the wall surface of each member of the air intake system tends to be positively charged. .
It is also known that the air flowing through the intake system also tends to be positively charged.

When positively charged air flows through a positively charged wall surface, a repulsive force acts between the wall surface and the air. Therefore, it is easily assumed that the air becomes difficult to flow in the vicinity of the wall surface.

In Patent Document 1, for the purpose of suppressing the difficulty of air flowing in the vicinity of such a wall surface, a self-discharge type static eliminator is installed on the wall surface to suppress charging of the wall surface, thereby reducing the amount of intake air. It is described that the intake efficiency can be improved.

JP 2016-78640 A

For example, vehicles such as automobiles and motorcycles equipped with an engine as a combustor preferably have a large maximum output from the viewpoint of speed, and a large maximum torque from the viewpoint of acceleration. In order to improve it, it is necessary to improve the combustor, and for ordinary people, such improvement is not easy. Therefore, it would be preferable if even an ordinary person could improve the maximum output and maximum torque of the combustor without making such improvements.

When the self-discharge type static eliminator described in Patent Document 1 is used in an intake device, the intake efficiency of intake air can be improved, specifically, the flow rate of intake air can be increased. There is room for improvement in terms of improving torque.

Each was evaluated based on the evaluation criteria. Table 1 shows the evaluation with the highest number of evaluations among the 10 people.
This sensory evaluation was divided into "sensory experience 1" from the start of running to 30 km/h and "sensory experience 2" from 30 km/h to 80 km/h. Moreover, the physical sensations 1 and 2 were evaluated before the laminate was attached, that is, compared with Comparative Example 5 below.

[Example 2]
A double-sided tape (Teraoka Seisakusho Co., Ltd., product name: #7783, thickness: 0.13 mm) is pasted on a copper foil with a thickness of about 50 μm, and a glass fiber sheet (glass cloth, Nippon Glass Fiber Industry ( Co., Ltd., product name: NGC-330-100-50m, thickness: 0.4 mm) were laminated. Next, a double-sided tape (manufactured by DIC Corporation, product name: Daitac #8180, thickness: 0.14 mm) is attached to the glass fiber sheet, and an aluminum-containing film (manufactured by Lintec Corporation, thickness: 50 μm) is attached. ) to prepare a laminate in which a copper foil, a glass fiber sheet and an aluminum-containing film were laminated in this order.

<Confirmation of antistatic property>
One sheet of the laminate obtained in Example 2 was placed on the outer wall near the outlet of a vinyl chloride pipe (length 0.8 m) with a diameter of 3 cm. It was attached using vinyl tape. Air was flowed at a rate of 6000 L/min into the vinyl chloride tube to which the laminate was attached, and the surface potential of the vinyl chloride tube at the air outlet was measured using a multi-function static electricity measuring instrument "STATIRON DX" manufactured by Shishido Static Electricity Co., Ltd. was measured using
