CN103937447A - Anti-low-temperature crack pouring glue and processing technology thereof - Google Patents

Abstract

The invention relates to anti-low-temperature crack pouring glue and a processing technology thereof and particularly relates to an asphalt material which can be widely applied to waterproofness of roads, bridges and roofs. The anti-low-temperature crack pouring glue is realized through the following technical scheme: the formula comprises the following components in percentage by weight: 1-8% of a styrene-butadiene copolymer, 5-30% of recovered rubber powder, 2-20% of aromatic hydrocarbon oil, 0.1-0.25% of a stabilizer (sulfide) and the balance of #70 and #90 asphalts. The processing technology comprises the following steps: 1) adding matrix asphalt into the aromatic hydrocarbon oil, and heating to 160-200 DEG C; 2) putting the styrene-butadiene copolymer to be uniformly stirred to grind and refine till no particulate matters are observed by naked eyes; and 3) finally, putting the stabilizer to stably stir for 0.5-1 hour to produce a required product, namely the anti-low-temperature crack pouring glue. According to the anti-low-temperature crack pouring glue provided by the invention, as the rubber powder is added, by means of a long bond structure of a chain, the rubber powder is degraded under a certain condition, and the modified asphalt is re-processed, so that the high high-temperature flowing resistance performance is realized, and the low-temperature flexibility is further considerably excellent. At -40 DEG C, the anti-low-temperature crack pouring glue can be randomly twisted without breakage, and the low-temperature cracks experiencing a relative high temperature further can be fully repaired.

Technical field

The present invention relates to engineering construction technical field, refer in particular to a kind of bituminous material that is widely used in highway, bridge, roof waterproof.

Background technology

Bituminous pavement, the cement pavement being widely adopted now have wear resistance good, do not play the advantages such as dirt, motor-driven vehicle going braking is good, but, in the winter of low temperature, the shortcoming of poor performance at low temperatures makes it be easy to be full of cracks, the process of wheel, the etch of sleet, makes be full of cracks place be easy to breakage, thereby causes the damage on road surface.Moreover the shortcoming that separately has a maximum is the bituminous pavement cast of must scene heating, seriously polluted, labor intensity of operating staff is large.

Summary of the invention

The object of the invention is to overcome due to above-mentioned weak point of the prior art, and a kind of anti-low temperature base joint grouting glue and complete processing are provided.

The present invention is achieved through the following technical solutions: its formula is for the following content of: ﹙ is Wei Chong amount Bai Fen Bi ﹚ styrene-butadiene copolymer 1%～8%; Reclaim rubber powder 5%～30%; Aromatic hydrocarbon oil 2%～20%; Wen is Dinged Ji ﹙ Liuization Wu ﹚ 0.1-0.25%; All the other are No. 70, No. 90 level pitches.Its complete processing is: 1 ﹚ aromatic hydrocarbon oil adds in matrix pitch, is warmed up to 160 DEG C～200 DEG C; 2 ﹚ input styrene-butadiene copolymers (SBS) stir and carry out overground refinement, and visual inspection is without particulate matter; 3 ﹚ finally throw in stablizer and stir to stablize to process for 0.5～1 hour and produce desired product.

Advantage of the present invention is:

﹙ 1 ﹚: high softening temperature, can reach 85 DEG C, 135 viscosity reach 4Pa.s left and right;

﹙ 2 ﹚: have excellent storage stability, this product stores for a long time without segregation, and index is stable;

﹙ 3 ﹚: low-temperature performance is good ,-40 DEG C of cryogenic tensiles meet correlation technique requirement completely;

﹙ 4 ﹚: construction easily, only needs fracture place to carry out preliminary cleaning and drenches at breakage watering after this material melts.

﹙ 5 ﹚: there is good anti-damage by water, anti-severe cold, anti-aging effect;

﹙ 6 ﹚: energy-conserving and environment-protective, adopt and reclaim rubber powder and make, to lower and pollute, construction adopts electrically heated, effectively protects construction environment and personal security.
