Preparation method of asphalt waterproof roll

Abstract

The invention belongs to the technical field of waterproof material preparation, and particularly relates to a preparation method of an asphalt waterproof roll. The preparation method comprises the following steps of 1, heating asphalt: heating an asphalt block with a surface layer cut off until the asphalt block is melted into a molten state; 2, impregnating embryo materials: putting the embryo materials into the asphalt in the molten state so that the surfaces of the embryo materials can be impregnated with the asphalt; 3, scraping at a constant thickness: completely removing the asphalt onone sides of the embryo materials, and scraping the asphalt on the other sides of the embryo materials at a constant thickness; and 4, cooling and rolling: cooling the asphalt on the surfaces of the embryo materials until an asphalt layer is cooled into a solid state and then rolling. An asphalt waterproof roll preparation machine is used to complete the step 2 and the step 3. According to the preparation method, it is ensured that the asphalt on one sides of the embryo materials is removed thoroughly, so that the occurrence of the uneven asphalt on one sides of the embryo materials is avoidedafter cooling; and it is ensured that the scraped asphalt falls back into asphalt in a cavity, so that the material waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of waterproof material preparation, and in particular relates to a method for preparing an asphalt waterproof coiled material. Background technique [0002] Bitumen waterproofing membrane, also known as linoleum, is a common medium and low-grade waterproof material. Bituminous waterproofing rolls are divided into tire rolls and tireless rolls; rolls made of thick paper or glass cloth, asbestos cloth, cotton and linen fabrics and other tires impregnated with asphalt in a molten state are called tire rolls. Asbestos and rubber powder are mixed into the asphalt material in the molten state, and the roll material made by rolling is called tireless roll material. The tire coils are divided into single-sided tire coils and double-sided tire coils. At present, there are the following problems in the preparation of single-sided tire coils: (1) It is difficult to clean the asphalt on one side of the tire material, ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method for preparing bitumen waterproof coiled material, aiming to solve the following problems existing in the preparation of single-sided tire-coated coiled material: (1) It is difficult to clean the asphalt on one side of the tire material, resulting in the cooling of the tire material after cooling. There will be uneven asphalt material on one side, which will affect the use effect of the bitumen waterproof membrane; (2) when the asphalt on the surface of the tire material is scraped to a certain thickness, the scraped asphalt material cannot be recycled, resulting in raw material waste of
