Problems solved by technology

[0004] At present, the road and bridge waterproofing membranes used in the market are mainly styrene-butadiene-styrene block copolymers and APP modified asphalt waterproofing membranes, which have excellent high temperature resistance, impact resistance and shear performance, but These two products also have their shortcomings. For example, hot melt construction must be used during construction, and the coiled material needs to be baked so that the modified asphalt layer of the coiled material can be thermally melted before paving. Open flames are used at the construction site. There are also certain safety hazards; and the bonding strength between these two products and several sides is not very large, and the low temperature resistance of APP coils is not very ideal.

preparation example Construction

[0027] A preparation method for self-adhesive waterproof roll material for road and bridge, comprising the steps of:

[0028] ① Weigh 40-60 parts of No. 90 asphalt and 10-20 parts of softened oil according to the parts by mass, mix, stir, and heat up to 185-195°C;

[0029] ② Add 3~10 parts of styrene-butadiene-styrene block copolymer, 2~5 parts of styrene-butadiene rubber, 3~8 parts of recycled polypropylene, 0.5~3 parts of high-temperature modifier, and keep the temperature at 190~ 200°C, high-speed stirring and shearing for 2 hours;

[0030] ③After the pellets are completely melted, heat up to 200~210℃, add rubber powder for 5~15°C, stir and shear at high speed for 2h;

[0031] ④Add 25~40 parts of filler, keep the temperature at (170+10)℃, stir and shear at high speed for 1 hour, the mixture is ground and sheared by a colloid mill, and circulated 2~3 times to obtain a polymer modified asphalt mixture;

[0032] ⑤After checking that all indicators meet the requirements, open...

Embodiment 1

[0034] The mass parts of each component of self-adhesive waterproof coiled material for road and bridge of the present invention are as follows:

[0035] 50 parts of No. 90 asphalt, 14 parts of softening oil, 5 parts of styrene-butadiene-styrene block copolymer, 4 parts of styrene-butadiene rubber, 4 parts of recycled polypropylene, 1 part of high-temperature modifier, 7 parts of rubber powder And 32 parts of filler.

[0036] In this example, No. 90 bitumen is No. 90 bitumen from Qinhuangdao PetroChina Fuel Asphalt Co., Ltd., the softening oil is aromatic oil from Shandong Jiangshan Polymer Material Co., Ltd., and the styrene-butadiene-styrene block copolymer is from Sinopec For 1401, the styrene-butadiene rubber is P-styrene-butadiene rubber from Shandong Gaoshi Technology Industry and Trade Co., Ltd., the recycled polypropylene is green recycled polypropylene from Hongxing Plastic Factory in Qingyun County, Shandong Province, and the high-temperature modifier is Lotader resi...

Abstract

The invention relates to self-adhesion waterproof rolls used for a road bridge. The self-adhesion waterproof rolls used for the road bridge comprises, by weight, 40-60 parts of asphalt No.90, 10-20 parts of softening oil, 3-10 parts of styrene-butadiene-styrene block copolymer, 2-5 parts of butadiene styrene rubber, 3-8 parts of reclaimed polypropylene, 0.5-3 parts of high temperature modifier, 5-15 parts of rubber powder and 25-40 parts of stuffing. The self-adhesion waterproof rolls used for the road bridge has excellent high-and-low temperature resistance performance, is imperious, impact-proof, anti-shearing and large in bonding strength, and has self-healing creep performance. Fire baking is not required in construction, cold construction is adopted, the construction method is simple, and the construction efficiency is high.

Description

technical field [0001] The invention relates to a waterproof coiled material and a preparation method thereof, in particular to a self-adhesive waterproof coiled material for roads and bridges and a preparation method thereof. Background technique [0002] In recent years, my country's transportation industry has developed rapidly, and there are more and more overpasses, viaducts, expressways, railways, etc., and a large number of roads and bridges that are under construction or have not yet been built provide convenience for people to travel, but their normal service life is also doubled. focus on. The quality of road and bridge waterproofing directly affects its normal service life. Often due to inadequate waterproofing links and repeated impacts, stretching, shearing and temperature stresses of vehicle loads, the negative bending moment of reinforced concrete beams and reinforced concrete Fine cracks in the bridge deck cause problems such as water seepage, pits, collapse,...
