Problems solved by technology

The effect of directly laying waterproof membranes is much worse than that of laying on a flat substrate. Due to the corrugated structure, the pressure roller cannot be used to roll the membranes. The corrugated structure of the steel tile
In the prior art, construction workers step on both sides of the corrugated structure to make the waterproof coiled material and the color steel tile fit together, but the inclination angles of the shoe and the corrugated structure of the corrugated steel tile are not consistent, and the waterproof coiled material cannot be aligned with the corrugated structure. The color steel roof is fully fitted
In this way, not only the laying efficiency is low, but also the bonding fastness between the laid waterproof membrane and the color steel roof is poor.

Embodiment 1

[0038] This embodiment relates to a construction process of PET self-adhesive polymer modified asphalt waterproof membrane, including the following steps:

[0039] Step 1: Base surface treatment: Use tools such as shovels and scrapers to remove rust and sundries on the surface of the color steel roof to keep the color steel roof clean and free from open water. Set the reference line on the color steel roof, and apply the adhesive evenly on the color steel roof. The thickness of the adhesive is 2mm.

[0040] Step 2: Measure the angle between the color steel roof and the color steel tile corrugated structure to be 125°, slide the connecting rod 4 on the vertical bar 1, so that the angle between the inclined side plate 3 and the horizontal side plate 2 is 125°, move the limit block 5 to the place where it abuts against the connecting rod 4, so that the connecting rod 4 is fixed.

[0041]Step 3: Reserve an 8cm margin on the edge of the waterproof membrane, uncover the isolation f...

Embodiment 2

[0049] The difference between the present embodiment and the first embodiment mainly lies in that: 5 cm is reserved at the edge of the waterproof membrane when laying; the formulation of the waterproof membrane and the adhesive are different.

[0050] The modified asphalt layer of PET self-adhesive polymer modified asphalt waterproofing membrane is made of the following raw materials in parts by weight: 48 parts of 90# petroleum asphalt, 11 parts of SBS modifier, 4 parts of SBR modifier, and 6 parts of naphthenic oil parts, 5 parts of tackifying resin, 1.8 parts of dilauryl thiodipropionate and 25 parts of heavy calcium. The tackifying resin is composed of rosin resin and hydrogenated petroleum resin in a mass ratio of 1:4.5.

[0051] The low-temperature flexible adhesive is made of the following raw materials in parts by weight: 60 parts of 90# petroleum asphalt, 12 parts of SBS modifier, 2 parts of SBR modifier, 1 part of naphthenic oil and 18 parts of heavy calcium.

Embodiment 3

[0053] The difference between the present embodiment and the first embodiment mainly lies in that: when laying, the reserved edge of the waterproof membrane is 12 cm; the formula of the waterproof membrane and the adhesive is different.

[0054] The modified asphalt layer of PET self-adhesive polymer modified asphalt waterproofing membrane is made of the following raw materials in parts by weight: 50 parts of 90# petroleum asphalt, 12 parts of SBS modifier, 5 parts of SBR modifier, and 8 parts of naphthenic oil parts, 8 parts of tackifying resin, 3 parts of trinonylphenyl phosphite and 30 parts of heavy calcium. The tackifying resin is composed of rosin resin and hydrogenated petroleum resin in a mass ratio of 1:4.5.

[0055] The low-temperature flexible adhesive is made of the following raw materials in parts by weight: 62 parts of 90# petroleum asphalt, 12 parts of SBS modifier, 3 parts of SBR modifier, 2 parts of rubber oil and 20 parts of heavy calcium.

Abstract

The invention relates to the technical field of waterproof rolls, in particular to a PET self-adhesion polymer modified asphalt waterproof roll construction technology. According to the technical scheme, the construction technology comprises the steps that iron rust and debris on the surface of a basal plane are removed, the basal plane keeps clean and waterless, a reference line is snapped on thebasal plane, and the basal plane is uniformly coated with an adhesive; the included angle between the basal plane and a protrusion on the basal plane is measured, and the angle of an angle plate is set to be equal to the included angle; a connection edge part of 5-12 cm is preserved at the edge of the waterproof roll, a separation film of the waterproof roll is removed, and the waterproof roll islaid on the adhesive along the reference line, wherein during laying, the waterproof roll is pressed by using the angle plate, so that the waterproof roll is tightly attached to the protrusion on thebasal plane. The construction technology has the advantages that the laying efficiency is high and it can be achieved that the roll is completely and tightly attached to the basal plane, and the construction technology is suitable for laying the waterproof roll on a colored steel roof.

Description

technical field [0001] The invention relates to the technical field of waterproof membranes, in particular to a construction process of PET self-adhesive polymer modified asphalt waterproof membranes. Background technique [0002] The color steel roof is a profiled plate that rolls and cold-bends color-coated steel sheets into various waveforms. Due to its light weight, convenient construction, and recyclability, it has been more and more used in the construction field, especially in some large-scale construction projects such as railway stations, theaters, and large shopping malls. The share is increasing year by year. However, with the widespread use of color steel roofs, leakage and corrosion have also occurred during the application process. [0003] At present, the waterproofing of color steel roofs is mostly realized by laying waterproof membranes, and the several corrugated structures on the color steel roofs add difficulty to the laying of membranes. The effect of ...
