Example Embodiment

[0029] Example 1

[0030] A production process of thick-layer asphalt waterproof membrane, such as figure 1 , 2 It includes the following steps:

[0031] S1 Preparation of the main body layer 7: After pre-soaking the tire base 1 in a dipping tank, squeeze it dry, cool it, and then put it into the coating tank with coating material, adjust the height position of the tire base 1, and make it through the coating roll The coating material is respectively coated on the upper surface and the lower surface of the tire base 1, so that the upper surface of the tire base 1 forms an upper surface coating layer 2 with a thickness of t1, and the lower surface of the tire base 1 forms a first lower surface with a thickness of t3. The surface is coated with a cover layer 3, and t3 is less than t1, and then the cover layer 2 is coated on the upper surface with a cover layer film 4 to obtain the main body layer 7;

[0032] S2 Preparation of the lower layer 8: the unwinding mechanism 10 releases the ...

Abstract

The invention relates to the technical field of modified asphalt waterproof rolls and in particular relates to a production process of a thick-layer asphalt waterproof roll. The process comprises thefollowing steps: preparing a main body layer, preparing a lower surface layer and preparing the thick-layer asphalt waterproof roll, namely respectively coating an upper surface coating layer and a first lower surface coating layer on the upper surface and the lower surface of tread so as to prepare the main body layer, performing knife coating on a second lower surface coating layer on a bottom film so as to prepare the lower surface layer, and laminating the main body layer and the lower surface layer, thereby obtaining the thick-layer asphalt waterproof roll. The thick-layer asphalt waterproof roll produced by the production process has the advantages of being uniform in coating material thickness, excellent in waterproof performance, simple in production process, low in production costand the like.

Description

technical field [0001] The invention relates to the technical field of modified asphalt waterproof coiled material, in particular to a production process of thick-layer asphalt waterproof coiled material. Background technique [0002] Waterproof membranes are mainly used in building walls, building basements, roofs, tunnels, etc., to resist external rainwater and groundwater penetration, and are the first barrier for waterproofing the entire project. Polymer modified asphalt waterproof membranes are Polyester tire, glass fiber tire, glass fiber reinforced polyester tire, etc. are used as tire bases, polymers are used as modifiers to modify asphalt as coating materials, and synthetic polymer films are used as covering materials. The sheet-like waterproof material is widely used because of its excellent high and low temperature resistance, good tensile performance, high elongation, good bonding performance, and strong self-healing property. [0003] Modified bitumen waterproo...
