Styrene-butadiene-styrene block copolymer (SBS) modified bitumen waterproof material has been widely used in road and bridge because of its excellent low temperature and waterproof performance. With the expansion of waterproof enterprise business, but in In some high-temperature areas, due to the limitation of environmental conditions, the traditional SBS modified asphalt waterproof material can no longer meet the requirements of use, and it is necessary to research and develop a high-temperature resistant waterproof material

Embodiment 1
[0020] 1) Weigh raw materials in proportion:
[0021]
[0022]
[0023] 2) Heat and dehydrate 90# heavy traffic road asphalt at 120°C, then heat up to 180°C, add third-line oil-reducing plasticizer, mix, heat and stir;
[0024] 3) Keep the temperature at 180°C, add anti-aging agent 4010, APAO modifier and styrene-butadiene-styrene block copolymer modifier and stir, the stirring speed is 400r / min, the stirring time is 2h, add filler Stir the talcum powder for 1h to discharge;
[0025] 4) Coat both sides of the modified material on the dipped and squeezed-out polyester tire, cover the surface or sprinkle sand to make samples, and then carry out corresponding performance tests.

The invention relates to a high temperature-resistant waterproof coating. The high temperature-resistant waterproof coating is prepared from the following materials in parts by weight: 30 to 45 partsof 90# heavy duty bitumen, 4 to 10 parts of anti-aging agent 4010, 10 to 20 parts of APAO (amorphous poly alpha olefin) modifier, 5 to 10 parts of styrene-butadiene-styrene block copolymer modifier, 0.5 to 2 parts of tertiary pressure-relief distillation oil plasticizer, and 15 to 25 parts of talcum powder. The high temperature-resistant waterproof coating and the preparation technology have the advantages that an SBS (styrene-butadiene-styrene) modifier can be in contact with water, weak acid, alkaline and the like, so that the tensile strength is high, the surface friction coefficient is large, the low-temperature property is good, the processing property is good, and the like; the APAO modifier has the advantages of strong weather-resistant property, excellent salt and alkaline-resistant property, good compatibility with SBS elastomer, asphalt and other raw materials, and the like, and the important and obvious auxiliary function is realized on the modifying of the SBS elastomer, such as high and low temperature property, and weather-resistant property; by utilizing the tertiary pressure-relief distillation oil plasticizer, the compatibility between the matrix asphalt and the modifier is improved.
Description
technical field [0001] The invention belongs to the field of waterproof materials, and in particular relates to a high-temperature-resistant waterproof material and a preparation process thereof. Background technique [0002] With the rapid development of my country's economy, the number of highways, roads and bridges has increased rapidly. However, many roads and bridges experience early damage less than a year after they were opened to traffic, and the most harmful and common type is water damage. In order to prolong the service life of roads and bridges and reduce maintenance costs, it is very necessary to lay waterproof layers on road and bridge decks. Since the 1980s, SBS modified bitumen waterproof material, as a new type of building waterproof material promoted by the state, has been rapidly popularized and developed in the building waterproof industry because of its moderate price, good waterproof effect, and convenient construction. Styrene-butadiene-styrene block...
