Problems solved by technology

Polyethylene polypropylene composite waterproof membrane is a popular waterproof material, but there are still many problems in the polyethylene polypropylene composite waterproof membrane on the market, such as poor waterproof performance, low tensile performance, and unsatisfactory environmental protection effect , complicated construction and other issues
[0003] At this stage, the technology of elastomer modified bitumen waterproof membrane (SBS) produced in China is basically mature, but there are still many problems, such as inaccurate dosage during the batching process, unstable temperature control during the oxidation process, and outdated rationing methods, etc. A series of reasons lead to unstable product quality, and there are defects in anti-aging, poor anti-oxidation ability, low elongation and short life
In the process of heating asphalt to produce asphalt products and the process of heating asphalt to prepare waterproof membranes, a large amount of asphalt fumes are generated, which has a serious impact on the surrounding environment and endangers people's health.

preparation example Construction

[0032] The present invention also provides a preparation method of odor-cleaning modified asphalt waterproofing membrane, the steps of which are as follows:

[0033] (1) Heat the asphalt to 170-180°C, add the measured waste rubber powder and SBS rubber, keep the heating at 190-200°C, turn on the agitator, and control the speed at 10-20rpm;

[0034] (2) After mixing evenly, after colloid mill grinding, add metered stabilizer, antioxidant, odor inhibitor and filler, stir for 30min, and prepare modified asphalt;

[0035] (3) Add the above-mentioned modified asphalt into the screw extruder, extrude the carcass through the screw extruder, and at the same time extrude the carcass, introduce the polypropylene cloth into a pair of drafting rolls from both sides at the same time, pass through Roller extrusion, the polypropylene cloth and the carcass are hot-compressed into one body, cooled and cooled, and finally a PE film is attached on the surface to form a waterproof membrane.

Embodiment 1

[0038] Weigh 35 parts of asphalt and heat it to 180°C, add 15 parts of waste rubber powder and 15 parts of SBS rubber that have been measured, keep the temperature at 200°C, turn on the agitator, and control the speed at 10rpm; after mixing evenly, grind it through a colloid mill, Add 0.5 parts of stabilizer, 0.5 parts of antioxidant, 0.5 parts of odor inhibitor and 10 parts of filler, and stir for 30 minutes to prepare modified asphalt; add the above-mentioned modified asphalt into the screw extruder, and extrude through the screw extruder Carcass, when extruded into carcass, polypropylene cloth is introduced into a pair of drafting rollers from both sides at the same time, and the polypropylene cloth and carcass are hot-compressed into one by extrusion through the rollers, cooled and cooled, and finally The surface is attached with PE film to form a waterproof membrane.

Embodiment 2

[0040] Weigh 45 parts of asphalt and heat it to 170°C, add 20 parts of waste rubber powder and 20 parts of SBS rubber that have been measured, keep the temperature at 190°C, turn on the agitator, and control the speed at 20rpm; after mixing evenly, grind it through a colloid mill, Add 2 parts of stabilizer, 1 part of antioxidant, 1 part of odor inhibitor and 20 parts of filler, and stir for 30 minutes to prepare modified asphalt; add the above-mentioned modified asphalt into the screw extruder, and extrude through the screw extruder Carcass, when extruded into carcass, polypropylene cloth is introduced into a pair of drafting rollers from both sides at the same time, and the polypropylene cloth and carcass are hot-compressed into one by extrusion through the rollers, cooled and cooled, and finally The surface is attached with PE film to form a waterproof membrane.

Abstract

The invention provides an odorless modified asphalt waterproofing coil material, which comprises modified asphalt, a polypropylene fiber cloth and a PE film, wherein the modified asphalt comprises, byweight, 35-45 parts of asphalt, 15-25 parts of waste rubber powder, 15-30 parts of an SBS rubber, 0.5-2 parts of a stabilizer, 0.5-1 part of an antioxidant, 0.5-1 part of an odor inhibitor, and 10-20parts of a filler. According to the present invention, the waterproofing coil material is produced by using the waste rubber powder, and the generation and volatilization of H2S, SO2, NOx and other asphalt flue gas during asphalt production and construction is reduced by using the action of the odor inhibitor, such that the significant odor elimination effect is achieved, the performance of the asphalt is not obviously changed, and the environmental protection and the health of personnel can be easily achieved. The invention further provides a preparation method of the odorless modified asphalt waterproofing coil material.

Description

technical field [0001] The invention belongs to the technical field of waterproof engineering materials, and relates to an odor-cleaning modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Since the 1970s, developed countries in the world have begun to change in the structure of waterproof materials, gradually developing to new waterproof materials such as modified asphalt, self-adhesive, and synthetic polymer materials. At present, foreign new waterproof materials have accounted for more than 90% of the total market, and product quality, function, and service life have reached a relatively high level. Since the application of asphalt membranes in my country's waterproof projects in the 1970s, asphalt waterproof materials have always been the leading product for building waterproofing, accounting for about 70% of the total market recently, and polymer waterproof materials accounted for only about 10%. For waterproof coa...
