Problems solved by technology

[0003] However, the existing modified asphalt waterproofing membranes have the following problems when they are cooled and rolled. distance, resulting in a reduction in the production efficiency of modified asphalt waterproofing membranes, and a single air cooling method is difficult to meet the cooling needs of the production of modified asphalt waterproofing membranes; The asphalt waterproofing membrane is in a loose state, which causes wrinkles to occur when the modified asphalt waterproofing membrane is rolled, making the modified asphalt waterproofing membrane uneven.

Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0037] Such as Figure 1 to Figure 10 As shown, a modified asphalt waterproof membrane production process mainly includes the following steps:

[0038] Step 1, material preparation, preparing the raw materials required for the manufacture of the modified bitumen waterproof membrane, and obtaining the raw material of the membrane;

[0039]Step 2, drying and stirring, drying the coil raw material obtained in step 1, and performing mixing, heating and stirring operation on the dried coil raw material to obtain the stirred raw material;

[0040] Step 3, extrusion molding, extruding the raw materials for making the polymer sheet layer to obtain the extruded sheet;

[0041] Step 4, film-attaching operation, coating the stirred raw material obtained in s...

Abstract

The invention relates to a production process of a modified asphalt waterproof coiled material. The process mainly comprises the following steps of material preparation, drying and stirring, extrusion molding, film pasting operation, cooling molding, packaging and warehousing, and used coiled material cooling molding equipment comprises a bottom plate, a spraying device, a soaking device, a tightening device and a winding device. The process can solve the following problems that when an existing modified asphalt waterproof coiled material is cooled and coiled, a, a traditional cooling mode of the modified asphalt waterproof coiled material is air cooling, and the production efficiency of the modified asphalt waterproof coiled material is reduced due to the fact the air cooling time is long, the cooling effect is poor, the cooling distance needs to be lengthened; and b, when the existing modified asphalt waterproof coiled material is coiled, the modified asphalt waterproof coiled material is in a loose state, the modified asphalt waterproof coiled material is wrinkled when being coiled, and the modified asphalt waterproof coiled material is unevenly coiled.

Description

technical field [0001] The invention relates to the technical field of waterproof material manufacture, in particular to a production process of modified asphalt waterproof coiled material. Background technique [0002] Waterproof membrane refers to the waterproof material product made by impregnating asphalt or polymer waterproof material on the carcass. Modified asphalt waterproof membrane and synthetic polymer waterproof membrane, waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills and other occasions, modified asphalt waterproof membrane needs to be It is cooled. [0003] However, the existing modified asphalt waterproofing membranes have the following problems when they are cooled and rolled. distance, resulting in a reduction in the production efficiency of modified asphalt waterproofing membranes, and a single air cooling method is difficult to meet the cooling needs of the production of modified asphalt waterproofing membranes; T...
