Embodiment 1

[0038] Preparation of tire-covering rubber for salt-alkaline-resistant polymer modified asphalt polyester tire waterproofing membrane

[0039] Add 90# heavy-duty asphalt into the 500L reactor according to the formula, turn on the heating device and raise the temperature to 150-160°C, add tackifying resin, SBS modifier, and softening oil according to the formula, start stirring, and heat up to 180°C while stirring Keep warm at about ±5°C, stir at a constant speed for 1.5-2 hours, until the modified material is fully mixed in the hot melt colloid, cool down to about 170±5°C, add ultrafine silica powder, ultrafine polypropylene fiber, and silane coupling agent YDH-550, heat preservation and stirring for 1.0~1.5h, turn off the heating device, naturally cool down to 140~150°C, use an asphalt pump to pump the prepared rubber material from the batching kettle into the forming storage kettle.

Embodiment 2

[0041] Scratch-coating process of tire-coated rubber sheet for salt-alkali-resistant polymer modified asphalt polyester tire waterproofing membrane

[0042] Such as figure 1 Shown, the sheet scraping process of the present invention is as follows:

[0043] 1. Melt glue discharge: Turn on the electric control switch of the melt glue storage kettle, set the temperature to 130-140°C, and open the discharge valve when the glue material has fluidity;

[0044] 2. Tire loading, tire stretching, and alignment;

[0045] 3. Coating, laminating, and heating to control the temperature at 130°C to 140°C;

[0046] 4. According to the thickness and weight, adjust the clamping distance between the coating die roller and the polyester tire, and turn on the cooling water of the coating roller.

[0047] 5. After the preparation steps are completed, the PLC coating button can be turned on; the glue supply pump pumps the glue into the coating roller machine, and the system automatically check...

Embodiment 3

[0050] Equipment operating procedure of the present invention

[0051] 1. Melt glue discharge: Turn on the electric control switch of the melt glue storage kettle, set the temperature to 140-150°C, and open the discharge valve when the glue material has fluidity;

[0052]2. Tire loading preparation: put the long-fiber polyester tire and PE anti-adhesive film on the unwinding rack, pass through the coating pair of rollers and the middle of the film-coating pair of rollers, and pass through the cooling roller, storage and adjustment rack, etc. until winding;

[0053] 3. Clean up and pay attention to whether there is any foreign matter on the coating roller; set the heating temperature to 130-140°C and heat to adjust the clamp distance between the roller and the coil, and determine it with plug R;

[0054] 4. Coating: When the glue in the glue storage kettle melts and reaches the set temperature, turn on the PLC main switch to set the running speed, and the cooling water in th...

Abstract

The invention discloses a saline-alkali tolerant high polymer modified asphalt polyester reinforcement waterproof coiled material, which comprises a layer of high-strength long fiber polyester reinforcement (PY) with the thickness ranging from 1.2mm to 1.4mm. Special super-viscous SBS (styrene-butadiene-styrene block copolymer) and chemical saline-alkali tolerant accessories are covered on two surfaces of the polyester reinforcement to modify rubber asphalt, and the polyester reinforcement, the modified rubber asphalt and a PE (polyethylene) black film or fine sand materials are jointly used for preparing the saline-alkali tolerant high polymer modified asphalt polyester reinforcement waterproof coiled material by the aid of special process. The saline-alkali tolerant high polymer modified asphalt polyester reinforcement waterproof coiled material realizes excellent chlorine ion permeation performance and saline-alkali tolerance when used in building waterproofing engineering in coastal areas and high-saline and high-alkali areas, and can effectively prevent a building structural main body from being eroded by corrosive media.

Description

technical field [0001] The invention belongs to the field of building waterproof materials, and relates to a multi-layer composite waterproof material with superior performance, in particular to a chemical salt-alkali-resistant high polymer modified asphalt polyester tire waterproof coiled material. Background technique [0002] Waterproof materials are the most indispensable building materials used in civil engineering, housing construction, water conservancy, bridges and other projects in today's society. However, most waterproof materials are acid-base, and people often don’t know how acid-base will affect the building. It just so happens that the acid and alkali are already quietly corroding the steel bars, thus endangering the structural safety of the building, making it difficult to repair over time. and recovered losses. [0003] The waterproofing of underground buildings in coastal areas and high-salt-alkali areas has always been a big problem that plagues the water...
