Abstract
The waterproof paint is produced by mixing the components including petroleum, water, neoprene latex, emulsifier, activater, etc. It is stable in performance, fast in filming speed, high in shearing, cohesive and rupture strength, high in elongation, waterproof, and anti-seeping, so that it is suitable for use in bridge surface.
Description
The invention belongs to the construction waterproof coating field, it is a kind of waterproof paint specially for bridge surface.
Build highway and urban road, especially highway and urban interchange, investment is all several hundred million to tens, and bridge accounts for about the 10%-30% of total cost, the bridge cost is very high, therefore requires design life longer, generally then will reach more than 50 years, after yet some bridge built up, serious disease had just appearred in the more than ten years. Even cave in, water permeating of bridge floor is to affect a bridge key factor in service life.
Prestressed concrete bridge sweat, the particularly seepage of winterization brine ice have become one of Major Diseases of bridge structure to the structure in negative bending moment district and the corrosion of compressor wire, and its result is with the durability of grievous injury bridge structure. In general, cement concrete material is water-resistant material, can keep strength and stability in wet environment or in the water, but is in for a long time under the dampness, is in especially that concrete endurance issues allows of no optimist under the state of alternation of wetting and drying circulation. The white China in the surface that the problem that generally can occur has alkali one aggregate reaction, carbonization reaction, chlorine salt corrosion and floorings percolating water to bring. These reactions then cause bridge floor to produce and mould to be split.
The problems referred to above cause bridging person's enough attention, and launch research work for this reason. Because the present domestic waterproof paint specially for bridge surface that there is no, and bridge waterproof material type, technical indicator and mechanical characteristic all are different from the common buildings waterproof material, so existing building water-proof paint resistance to elevated temperatures (about 140 ℃) does not meet the requirement of bridge deck water-proof, bridge surface waterproof layer is except waterproof, the bitumen concrete (140 ℃-160 ℃) of also will mating formation thereon, therefore its watertight composition resistance to elevated temperatures must reach 140 ℃-160 ℃, but also will have certain crushing resistance, the index such as anti-shearing. Existing various highway, waterproof paint of chloroprene latex pitch for building can not be directly used in bridge deck water-proof for this reason.
The object of the present invention is to provide a kind of waterproof paint specially for bridge surface, this coating film forming is fast, shearing strength and adhesion strength is high, breaking resistance is good, extensibility is large, water proof anti-seepage.
Above-mentioned purpose is achieved through the following technical solutions: a kind of waterproof paint specially for bridge surface, contain material modified polychloroprene latex, pitch, water and emulsifying agent, and it is characterized in that the formula constituent (by weight percentage) of this waterproof paint specially for bridge surface is:
Pitch 25-35%; Defoamer 1-3%;
YH 10-18%; Cellulose 3-5%;
Water 40-50%; Polyvinyl alcohol 8-12%.
Emulsifying agent 2-4%;
Surfactant 1-5%;
Described pitch can be used 10#, 60# or 100# asphalt;
Described emulsifying agent is selected emulsifier op-10;
Described surfactant is cationic active agent OR (1831) or DR (1231);
Described YH also available natural rubber substitutes;
Described waterproof paint specially for bridge surface optimum formula component (by weight percentage) is: pitch 30%; Water 40%; Emulsifier op-10 3%; YH 14%; Cationic active agent OR (1831) 1%; Defoamer 2%; Cellulose 4%; Polyvinyl alcohol 10%.
Characteristics of the present invention are that the coating source of water-repellent paint is wide, performance is good, cost is low, is beneficial to all kinds of bridge floor waterproof, improve bridge service life; The film forming speed of this coating is fast, shearing strength and adhesion strength are high, and breaking resistance is good, and extensibility is large; Use this coating to have high temperature and do not trickle, not embrittlement of low temperature, water proof anti-seepage, freeze proof, anticorrosive ageing-resistant performance are good; The main performance test index sees the following form
