Problems solved by technology

Among them, the solvent type is an obsolete product due to serious pollution and waste, and is basically not used; the water emulsion type waterproof coating is fast in construction, pollution-free, and has a high degree of mechanization, but the modified emulsified asphalt currently used is basically a single modified product. There are many deficiencies in performance, and all such products currently used are thin coatings, and even the thickness of coating for multiple times does not exceed 1mm. Not suitable for the rapid development of modern transportation

Embodiment Construction

[0027] High-performance chemical network modified emulsified asphalt bridge deck waterproof material, its operation is as follows:

[0028] (1) Lanlian AH-90# petroleum asphalt and water are used as the main raw materials, and the oil-water ratio is 1.2-1.8.

[0029] (2) Use cationic surfactant cetyl trimethyl ammonium bromide (1631), octadecyl trimethyl ammonium chloride (1831), coconut oil propylene diamine, etc. and nonionic surfactant OP 4:5:4:3 compound use, the dosage is about 0.5-1.5% of the total water consumption.

[0030] (3) Select styrene-butadiene-styrene block copolymer (SBS) and styrene-butadiene rubber (SBR) (SBS: SBR = 3.5: 1.5) latex as the chemical modification matrix, and the dosage is 6.0-9.0 of asphalt %.

[0031] (4) select the material of excellent strong oxidation catalysis such as benzoyl peroxide, ammonium persulfate to be the 0.1%-3.0% of modifying agent for active initiator consumption; Select chemically active material such as styrene monomer, c...

Abstract

A high-performance chemical-structured modified emulsified binding water-proofing material for bituminized bridging floor takes AH-90# petroleum asphalt and water as main raw material in proportion of 1.2-1.8, and it takes cation surface activator 1631 and 1831 and cocoanut oil propylene bisamine and OPin proportion of 4:5:4:3, it selects SBS and SBR latex in proportion of 3.5:1.5 as chemical modified mother, and it uses epoxy-resin emulsion as additive. It has better binding ability, excellent low and high-temperature resistances and no environmental pollution.

Description

Technical field [0001] The invention belongs to special bonded waterproof materials for highways and bridge decks, in particular to a high-performance chemical network modified emulsified asphalt bridge deck bonded waterproof material. Background technique [0002] At present, my country lacks special bonded waterproof materials for bridge decks with excellent performance. Generally, materials used for roof waterproofing are diverted to bridge decks. There are two main categories: one is hot-melt coils. Although the hot-melt construction method is beneficial to improve the bonding force between the coiled material and the bridge deck, the controllability of manual construction is poor, and there are problems such as local over-temperature damage and uneven bonding, resulting in local waterproofing failure and resistance to the bridge. The ability of surface deformation and cracks is poor. In addition, the construction of this method has the d...
