[Detailed description of the invention] (Industrial application field) This invention is a bituminous mixture (hereinafter referred to as "mixture material").
The present invention relates to a protective sheet for covering composite material when it is transported by a dump truck or the like. (Conventional technology) When transporting heated composite materials from a production factory to a construction site using a dump trap, etc., it is necessary to prevent heat radiation from the composite materials and precipitation from falling on the composite materials, and to prevent the composite materials from scattering during transportation. In order to prevent this, a protective sheet is covered as shown in FIG. (Problem to be solved by the invention) Conventionally, as this type of protective sheet, a cotton or linen woven fabric has been used. However, this zutsuk has poor flexibility, so when used as a protective sheet, a thin zutsuk is used to ensure workability. However, since zutsuku has air permeability and water permeability, it does not have a sufficient heat insulation effect on the mixed material during transportation, and the thin sheet also causes deterioration of the mixed material due to contact with air. This idea was made in view of the above circumstances.
The purpose is to provide a heat insulating sheet that has an excellent heat insulation effect on the composite material during transportation of the composite material, prevents contact between the composite material and air, and has high strength in use and good workability. (Means for Solving the Problems) In order to achieve this objective, the present invention laminates a synthetic resin having plasticity on one side of a cloth-like material made of heat-resistant fibers such as polyamide fibers or polyester fibers. Alternatively, it may be coated to provide airtightness, and the other side may be impregnated with an oil-repellent resin. The cloth-like material may be a base made of woven fabric, non-woven fabric, etc. made of heat-resistant organic fibers such as polyamide fibers or polyester fibers, or various inorganic fibers that have heat resistance of 180 to 250°C or higher. It is made up of materials. The top surface of the fabric is made of polyvinyl chloride, polyethylene,
Containing any one of polypropylene, polystyrene, or polyacrylonitrile, plasticity is added if necessary, and a heat-resistant plastic resin is laminated or coated to form an airtight resin film, and the bottom surface of the fabric is made of silicon. It is characterized by being impregnated with a resin, particularly an oil-repellent resin such as a silicone resin or a fluororesin mixed with aluminum powder. (Operations and Effects) Since the protective sheet for composite material according to the present invention has the above-mentioned structure, the air present in the fibers of the cloth-like object is held in an encapsulated state by being sandwiched between the resin parts on both sides of the cloth-like object. Ru. Therefore, the thermal conductivity in the thickness direction of the protective sheet is extremely low, and therefore the heat retention effect of the composite material is extremely high. Further, since the protective sheet has airtightness and watertightness, precipitation does not penetrate into the composite material during transportation of the composite material during rainy weather, and the amount of heat in the composite material is not dissipated into the atmosphere. Moreover, the protection sheet prevents outside air from coming into contact with the composite material, thereby preventing oxidation and deterioration. Since the other side of the fabric is impregnated with an oil-repellent resin, bitumen or bituminous mortar does not adhere to the fibers or fluff of the fabric, resulting in excellent releasability from the composite material. Since the protective sheet of the present invention has a high heat retention effect as described above, the thickness of the heat retention sheet can be reduced, and the workability of covering and removing the composite material is improved.
Furthermore, since the protective sheet according to the present invention uses a fiber cloth-like material as a base material, it can sufficiently exhibit the necessary tensile strength characteristics when covered with a composite material. Because of its high strength properties and excellent peelability, it is durable and can withstand repeated use, and can prevent the mixture from scattering during transportation. (Example) Figure 1 shows an example of the present invention in which a polyvinyl chloride thermoplastic resin layer 2 is laminated on the upper surface of a nonwoven fabric 1 made of wholly aromatic polyamide fibers, and aluminum powder is infiltrated on the lower surface. A protective sheet 4 having a thickness of about 2 mm is shown impregnated with silicone resin 3. FIG. 2 shows the state of use when the composite material 7 loaded on the loading platform 6 of the dump truck 5 is coated, and Table 1 below shows the experimental results of the heat retention effect. In the table, the temperature of the mixture at the time of departure from the factory is the average value measured at two points, and the temperature of the mixture upon arrival at the site is the average value measured at eight points.In both cases, the depth of the thermometer is measured at 30 cm. It is. The distribution difference in temperature of the composite material indicates the difference between the maximum value and the minimum value among the above-mentioned 8-point measurement values upon arrival at the site.
As is clear from Table 1, the protective sheet according to the present invention can be used not only when two sheets are stacked, but also when
This shows that even when only one canvas is used, the heat retention effect is higher than when two cotton canvases according to the prior art are used. 【table】
