More specifically, asphalt is molded into a rod shape using an extrusion molding machine, and the surface is coated with a thermoplastic synthetic resin; The present invention provides rod-shaped asphalt that prevents molded products from adhering to each other during storage.

ある。Asphalt is usually sold as a solid in a 50Kr paper bag, and when it is used, the asphalt is taken out of the paper bag, crushed into pieces of appropriate size, placed in a melting pot, and melted using fire. A method of waterproofing is being carried out while applying small amounts of water by means of water leaks. This work is done at the construction site, which is time consuming and extremely inefficient.In the present invention, instead of flowing the molten asphalt from a supply tank into the paper bag, it flows directly into the molding machine through the hopper of the extrusion molding machine, so that the melted asphalt is lowered from the softening point. It is extruded into a rod shape while being kept at a slightly high temperature, and then immediately blown with cold air, before the asphalt surface cools and solidifies, a low melting point thermoplastic synthetic resin film is evenly wrapped around it to make it adhere tightly to the asphalt surface.

ール共重合体等が適している。The synthetic resin film used in the present invention completely adheres to the asphalt surface at the temperature immediately after asphalt extrusion, prevents the asphalt molded product from adhering after cooling, and separates from the asphalt when the asphalt is melted and used. It is important to use a material that completely dissolves without causing any problems during construction, and low-melting point aliphatic and aromatic synthetic resins, especially polyethylene, vinyl acetate, and ethylene-vinyl acetate copolymers, are suitable. There is.

０℃〜１３０℃に保つようにする。It is necessary that the melting temperature of the asphalt in the extruder is higher than its softening point, but if it is too high, even if cool air is applied after extrusion, the asphalt will remain in a slurry state and cannot be formed into a rod shape, so it is necessary to soften the asphalt used. There are differences depending on the point, but in the case of normally used plain asphalt, it is 10
Try to maintain the temperature between 0°C and 130°C.

い。The length of the rod-shaped molded product extruded from the nozzle of a one-pass molding machine is preferably around 10 cm; if it is thicker than that, the solidification rate is slow and it takes too long to cool the asphalt to the center, making molding difficult. If it is too thin, it not only solidifies too quickly and cannot be formed into a rod shape, but also increases the amount of hot-melt synthetic resin mixed into the asphalt, resulting in extreme changes in physical properties (3), resulting in operational inefficiency. become a target. Further, the length of the rod-shaped body is preferably a length convenient for handling, for example, about 1 m.

に固化させ棒状アスファルトを得た。While keeping the temperature inside the cylinder at 120 to 140°C, use a screw to reduce the diameter to 1. Asphalt is extruded into a rod shape through the nozzle of Ocnr, and immediately after applying cold air, a thin strip of polyethylene film is wrapped around the asphalt surface. Immediately, the per-ethylene film was hot-melted to completely adhere, and the asphalt was completely solidified while blowing cold air to obtain rod-shaped asphalt.
