Polyurethane waterproof coiled material production and processing method

Abstract

The invention relates to the technical field of waterproof coiled materials, in particular to a polyurethane waterproof coiled material producing and processing method which comprises the following steps: step 1, screening raw materials, and mixing qualified raw materials; 2, the raw materials obtained after slurry mixing are added into an extruder, extrusion molding treatment is conducted on the raw materials, then high-temperature vulcanization treatment is conducted on the raw materials obtained after extrusion molding, and processing of the coiled material is completed; step 3, adding polyurethane into a fuse machine, and processing solid polyurethane into liquid polyurethane; and 4, liquid polyurethane is added into the smearing device, the processed coiled material penetrates through the smearing device, and processing of the polyurethane waterproof coiled material is completed.

Description

technical field [0001] The invention relates to the technical field of waterproof rolls, and more particularly relates to a method for producing and processing a polyurethane waterproof roll. Background technique [0002] The waterproof membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage. There is no leakage connection with the building, which is the first barrier of the entire project waterproofing, and plays a vital role in the entire project. The existing asphalt waterproofing membrane and polyurethane waterproofing membrane appear. It has toxic elements, so the asphalt waterproofing membrane is gradually eliminated. The current polyurethane waterproofing membrane is the main waterproofing membrane, but the existing technology cannot efficiently produce and process the polyurethane waterproofing membrane.

Problems solved by technology

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no seepage connection between the building and it is the first barrier for the waterproofing of the whole project, which plays a vital role in the whole project, and the existing asphalt waterproofing membrane and polyurethane waterproofing membrane, because the asphalt interior There are toxic elements, so the asphalt waterproofing membrane is gradually eliminated. The current polyurethane waterproofing membrane is the main waterproofing membrane, but the existing technology cannot efficiently produce and process the polyurethane waterproofing membrane.
