preparation example 1

[0064] Preparation 1: Preparation of Comparative Asphalt I

[0065] (1) Removal of 50 # asphalt in the component treatment, resulting in a deprotected asphalt;

[0066] The removal component treatment is: the stirring speed is 1400 rpm, the starting temperature is 130 ° C, the temperature rise rate is 2 ° C / min, and the end temperature is 160 ° C;

[0067] (2) In the presence of oxygen, control the conditions of deprinted asphalt for dewaxing treatment, resulting in a wax content of 1.2% by weight;

[0068] The conditions of the dewaxing treatment are: the stirred speed is 1400 rpm, the temperature is 270 ° C, and the time is 2.5 h;

[0069] (3) Mix the dewaxing asphalt with the 10 # asphalt to obtain a compound asphalt I;

[0070] The mixed condition is: the stirring speed is 1400 rpm, the temperature is 175 ° C, and the time is 50 min;

[0071] The weight ratio of 10 # asphalt and 50 # asphalt in the batch asphalt I is 1: 7, a flash point 255 ° C, and the asphalt content is 24...

[0072] Preparation 2: Preparation of Comparative Asphalt II

[0073] (1) Removal of 50 # asphalt in the component treatment, resulting in a deprotected asphalt;

[0074] The removal component treatment is: the stirring speed is 1300 rpm, the starting temperature is 130 ° C, the temperature rise rate is 2 ° C / min, and the termination temperature is 240 ° C;

[0075] (2) In the presence of oxygen, control the conditions of deprinted asphalt to perform dewaxing treatment, resulting in a wax content of 0.9 wt%;

[0076] The conditions of the dewaxing treatment are: the stirring speed is 1300 rpm, the temperature is 260 ° C, and the time is 2 h;

[0077] (3) Mix the dewaxing asphalt with the 10 # asphalt to obtain a compounded asphalt II;

[0078] The mixed condition is: the stirred speed is 1300 rpm, the temperature is 175 ° C, and the time is 50 min;

[0079] The amount ratio of 10 # asphalt and 50 # asphalt in the batch asphalt II is 1: 7, a flash point 252 ° C, and the asphalt co...

preparation example 3

[0080] Preparation 3: Preparation of Comparative Asphalt III

[0081] The institutional preparation is performed with the same procedure as the preparation 1, and the difference is that this system preparation example:

[0082] The conditions in step (2) are different, specifically, the stirred speed is 1200 rpm, the temperature is 240 ° C, the time is 1.5 h; the wax content of 2.1 wt% is obtained. Asphalt.

[0083] Preparation of a compounded asphalt III, the amount ratio of 10 # asphalt and 50 # asphalt in the compound asphalt III was 1: 7, a flash point 245 ° C, and the asphalt content was 23.5% by weight.

Abstract

The invention relates to the field of asphalt waterproof rolls, and discloses a modified asphalt waterproof roll sizing material composition, a modified asphalt waterproof roll sizing material and a preparation method and application of the modified asphalt waterproof roll sizing material. The composition contains two or more of the following components which are stored in a mixed manner or independently stored: compound asphalt, rubber operating oil, a plastomer modifier, an elastomer modifier and a filler, wherein the compound asphalt is a combination of 10# asphalt and 50# asphalt in a weight ratio of 1:(4-9), the flash point of the compound asphalt is greater than or equal to 240 DEG C, and the asphaltene content is greater than or equal to 23wt%. A waterproof roll prepared from the modified asphalt waterproof roll sizing material prepared from the composition provided by the invention has stronger binding power with a concrete base surface and a roll lap joint, and meanwhile, the waterproof roll also has excellent thermal aging low-temperature performance.

Description

Technical field [0001] The present invention relates to bitumen membrane field, in particular, relates to rubber modified bitumen membrane composition, rubber modified bitumen membrane and preparation method and application. Background technique [0002] Currently, when preparing polyester tire modified asphalt waterproofing membrane, usually 70 # 90 # asphalt or asphalt, the resulting production of waterproofing membrane after aging robust low temperature cracking resistance, and adhesive properties of the building construction of the base surface Difference. [0003] Modified bitumen membrane obtained prior art production of a large number of pores is easy to produce, and thus affect the appearance properties of the web, impermeable, web and results in increased mass after immersion in water. [0004] CN102559135A discloses a self-adhesive bitumen which comprises by weight percent: 45 to 65% bitumen, rubber oil 16 ~ 25%, SBS5 ~ 15%, SBR1 ~ 6%, petroleum resin 1 ~ 6%, EVA1 ~ 7% ...
