Problems solved by technology

The road and bridge deck pavement built in the early 1990s in China basically does not have a waterproof layer. Soon after it was put into use, the asphalt concrete pavement layer of the bridge deck showed serious damage, cracking, pits, and swelling. Seriously affect the service life of the bridge and the comfort and safety of driving

Embodiment 1

[0016] Water-emulsion type neoprene rubber modified bitumen waterproof coating and its preparation method, its raw material formula is composed of: 15-20 parts of petroleum asphalt; 25-35 parts of neoprene latex; 1-2 parts of resin; 1-1.5 parts of auxiliary agent , including: emulsifiers, stabilizers, film-forming aids, thickeners, dispersants, anti-settling agents; 0.5-0.8 parts of regulators, including: defoamers and 0.1-0.2 parts of pH regulators; defoamers It includes 0.2-0.6 parts of silicone defoamer and 0.2 parts of tributyl phosphate; 0.3-0.4 parts of plasticizer; 0.01-0.02 parts of vulcanizing agent; 5-10 parts of functional powder; 30-50 parts of water.

[0017] The preparation method of water emulsion type chloroprene rubber modified asphalt waterproof coating:

[0018] (1) Add 15-20 parts of petroleum asphalt into mixing tank A, slowly raise the temperature to 180°C, then cool down to 160-170°C, add 0.3-0.4 parts of plasticizer (for resin), 1-2 parts of resin , ma...

Embodiment 2

[0026] Below in conjunction with embodiment describe its construction method in detail:

[0027] (1) Preparation of construction tools: Mixing buckets, spraying machines or special bristle brushes should be prepared before construction.

[0028] (2) Requirements for the base course: the strength of bridge deck and beam concrete reaches the design mark, and the surface must not have loose laitance, peeling, hollowing and severe cracking. The flatness of the surface shall meet the requirements of the bridge specification. The elevation of the upper opening of the vertical drainage pipe shall be lower than that of the base layer. The outlet must be firmly installed with the base layer without any looseness.

[0029] (3) The base layer should be clean, dry and free of water.

[0030] (4) Base treatment: the base surface should be free of dust, floating ash, impurities, oil stains, etc. Before making the waterproof layer, the surface can be cleaned with air compressor, water purif...

Abstract

The invention discloses a water-emulsified chloroprene rubber modified asphalt waterproof paint and a preparation method thereof. The formula of the water-emulsified chloroprene rubber modified asphalt waterproof paint comprises the following raw materials: 15-20 parts of petroleum asphalt, 25-35 parts of chloroprene rubber latex, 1-2 parts of resin, 1-1.5 parts of assistant, 0.5-0.8 part of regulator, 0.3-0.4 part of plasticizer, 0.01-0.02 part of vulcanizing agent, 5-10 parts of functional powder and 30-50 parts of water, wherein the assistant comprises emulsifier, stabilizer, film-forming assistant, thickener, dispersant and antisettle agent; the regulator comprises defoaming agent and 0.1-0.2 part of pH value regulator; and the defoaming agent comprises 0.2-0.6 part of organic silicon defoaming agent and 0.2 part of tributyl phosphate. The waterproof paint is prepared from chloroprene rubber latex modified emulsified asphalt and can meet the waterproofing requirement of a concrete bridge floor.

Description

technical field [0001] The invention relates to a water-emulsion type neoprene rubber modified asphalt waterproof coating and a preparation method thereof. The waterproof coating is prepared by using neoprene latex modified emulsified asphalt and can meet the waterproof requirements of concrete bridge decks. Background technique [0002] In recent years, my country's road construction has developed rapidly, the road grade has been continuously improved, and the proportion of bridge structures is increasing. The bridge is an important part of the road. Its normal use plays a very critical role in the operation of the road. The road and bridge deck pavement built in the early 1990s in China basically does not have a waterproof layer. Soon after it was put into use, the asphalt concrete pavement layer of the bridge deck showed serious damage, cracking, pits, and swelling. Seriously affect the service life of the bridge and the comfort and safety of driving. Therefore, there i...
