Problems solved by technology

[0006] This kind of hot-melt elastomer modified asphalt waterproofing membrane can be laid on the top of the house to play a better waterproof effect, but due to the characteristics of asphalt and SBS itself, this kind of waterproofing membrane is highly sensitive to temperature. When the temperature is too high or the temperature is too low, curling, fluidization, cracking, etc. will occur

Embodiment 1

[0038] A kind of preparation method of modified asphalt waterproof coiled material, concrete steps:

[0039] ⑴Put 90# asphalt and 10# asphalt into the mixing tank, stir and heat to 160°C to get mixed asphalt;

[0040] (2) Add engine oil to the mixed asphalt to obtain a mixed solution, and continue heating the mixed solution to 180°C;

[0041] (3) Add styrene-butadiene rubber and activated rubber to the mixture, start the colloid mill twice while stirring, stir for 80 minutes, and control the temperature at 180°C;

[0042] (4) After stirring the mixture, wait for the temperature to rise to 200°C, add talcum powder, and stir for half an hour. After checking that the mixing ingredients are sufficient, a waterproof semi-finished product is obtained;

[0043] (5) Put the waterproof semi-finished product into the oiling tank. The temperature of the oiling tank is controlled at 165°C. Soak the polyester tire in the oiling tank containing the waterproof semi-finished product until th...

Embodiment 2

[0048] The preparation method is the same as that in Example 1. The raw materials used are the following parts by weight: 21 parts of 90# asphalt, 29 parts of 10# asphalt, 10 parts of styrene-butadiene rubber, 12.5 parts of activated rubber powder, 12 parts of machine oil, and 15.5 parts of filling materials .

Embodiment 3

[0050] The preparation method is the same as in Example 1, and the raw materials used are the following parts by weight: 21 parts of 90# asphalt, 29 parts of 10# asphalt, 10 parts of styrene-butadiene rubber, 12.5 parts of activated rubber powder, 12 parts of machine oil, and 15.5 parts of filling materials .

Abstract

The invention relates to a modified asphalt waterproof coil material and a preparation method thereof, and belongs to the technical field of chemical engineering. The modified asphalt waterproof coilmaterial is prepared from 90# asphalt, 10# asphalt, butadiene styrene rubber, activating glue powder, polyethylene membranes, polyester blanks, engine oil and filling materials. The 90# asphalt, 10# asphalt, YP03 activating glue powder, engine oil and other filling materials are added into the elastomer modified asphalt waterproof coil material; through the modification on the elastomer modified asphalt waterproof coil material by YP03 active rubber powder, the ingredient stirring process is studied; the process control parameters are changed; the proceeding of the ingredient stirring processin production at the lower temperature is realized; the high-temperature-resistant performance and the low-temperature softness performance are improved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, subways, landfills, etc., to resist external rainwater and groundwater leakage. It is a flexible building material product that can be rolled into rolls. As a non-leakage connection between the engineering foundation and the building, the waterproof membrane is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. According to its main waterproofing materials, it can be divided into asphalt waterproofing materials, There are three types of asphalt waterproofing membranes: polymer modified waterproofing membrane and synthetic polymer waterproofing membrane. [0003] Asphalt waterproofing membrane is a rollable sheet waterproof mate...
