Description

Mastic neoprene water-proof paint and production technique

The present invention relates to a kind of water-proof material and production technique, particularly a kind of mastic neoprene water-proof paint and production technique that is used for construction work protection against the tide, anti-leakage.

As everyone knows, water-proof material is requisite a kind of important materials in the construction work, and its quality good job directly has influence on engineering Ling worker's quality, need coated with water blocking material as roof, flooring, vault, warehouse, pond and water conservancy projects etc., reach the purpose of waterproof, protection against the tide, antiseep.What use in the prior art is traditional petroleum pitch water-proof material, exist easy embrittlement under easy trickling, the low temperature under the high temperature, play drum, be full of cracks, seepage easily, the waterproof effect instability, need carry out heat construction, problem such as labour intensity is big during construction, but cheap because of it, construction cost is low, be widely used always.The various asphalt modification water-proof materials and other water-proof materials that come next, as high-concentrated water-soluble water-proof coating (application number 90106875.6), high efficient water-proof painting material (application number 91108189.5) and waterproof paint (application number 89104899.5), these waterproof paints, it is many wherein to exist material component, the problem of processed complex, the raw material that has is toxic, the smell is awful, as triphen ethylphenol, propylene dichloride, influence the healthy of people, the raw material that has is in short supply, price is high, and as tung oil, vinylformic acid, thereby difficulty or ease are promoted the use of.

The object of the present invention is to provide a kind of have excellent protection against the tide, the mastic neoprene water-proof paint and the production technique of anti-leakage performance, overcome the deficiencies in the prior art part, it can carry out cold construction under humidity, dust atmosphere, the rete cohesive force is strong, high resilience, fast drying, no change in bubble.

Technical scheme of the present invention is as follows.

1, prescription: mastic neoprene water-proof paint, it comprises by 60# petroleum pitch, neoprene latex, PVA(17-88 type), emulsifying agent TOT.(or NOT.), filler and water is mixed with, its proportion of composing (weight ratio) is 60# petroleum pitch 53-56%, neoprene latex 4-8%, PVA(17-88 type) 2-4%, emulsifying agent TOT.(or NOT.) 0.3-0.6%, filler 1-2% and water 32-37%.

2, production technique: technology comprises the fusing of (1) petroleum pitch, to heat fusion in the petroleum pitch input fusing case, when temperature rises to 120-140 ℃, be fused into liquid, flow into then in the high-temperature cabinet (dewatering box), when containing water in the pitch, continue to be heated to 140-160 ℃, water evaporates is removed, be incubated to 120-130 ℃, rubber mill pours in the pitch hopper stand-by when starting, (2) emulsion preparation adds tap water and is heated to 100 ℃ in the hot well tank, flows into then in the stirred pot that adds PVA in advance, stirred 10-15 minute, treat that PVA all dissolves, add emulsifying agent TOT.(or NOT. then) and filler, continue to stir 5-10 minute to all dissolving mixing emulsification, be pressed into then in the insulation jar, be incubated 70-80 ℃, treat to be pressed in the emulsion hopper when rubber mill starts the preparation of (3) finished product, start rubber mill, rotating speed is 2900 rev/mins, opens pitch hopper and emulsion hopper, and pitch and emulsion flow in the rubber mill simultaneously and grind, fineness reaches the μ to 2-5, feed liquid after the grinding flows into the finished product pond, is cooled to 50-30 ℃, under agitation adds neoprene latex, treat to mix fully till the emulsification, the discharging can gets product.

Filler is U-Ramin MC, silicon-dioxide or water-ground limestone.

In the production process, heating system is by Oil Guide stove, header box, low level case, water-and-oil separator, strainer and carry thermal conductance oil sealing stopped pipe road to form, and adorns resistant to elevated temperatures Oil Guide in the Oil Guide stove.

Fig. 1 is the technological process of production synoptic diagram of the technology of the present invention.

Below in conjunction with embodiment the present invention is specified.

Operating procedure:

Pour into resistant to elevated temperatures Oil Guide in the Oil Guide stove, come high temperature oil in the process furnace by coal gas or electricity, temperature reaches 250-300 ℃, thermal conductance oil is delivered on the working face that needs heating with the high pressure transfer pump then, carry out coil pipe type and add thermal material, cooling after heat Oil Guide returns, and forms circulating pipeline and send heat.

(1) petroleum pitch fusing, take by weighing in the 60# petroleum pitch input fusing case and heat fusion, when temperature rises to 120-140 ℃, be fused into liquid, flow into then in the high-temperature cabinet (dewatering box), when containing water in the pitch, continue to be heated to 140-160 ℃, the water evaporation is removed, be incubated to 120-130 ℃, rubber mill pours in the pitch hopper stand-by when starting, (2) emulsion preparation, to be heated to 100 ℃ in the quantitative tap water adding hot well tank, flow into then and add quantitative PVA(17-88 type in advance) stirred pot in, stirred 10-15 minute, treat that PVA all dissolves, add emulsifying agent TOT.(or the NOT. that takes by weighing then) and filler, continue stirring extremely all dissolving mixing emulsification in 5-10 minute, be pressed into then in the insulation jar, be incubated 70-80 ℃, treat to be pressed into again in the emulsion hopper when rubber mill starts, (3) finished product preparation is started rubber mill, 2900 rev/mins of rotating speeds, open pitch hopper and emulsion hopper, pitch and emulsion flow in the rubber mill simultaneously and grind, and fineness reaches 2-5 μ, under agitation add the neoprene latex that takes by weighing, till complete mixing emulsification, the discharging can gets product.

The sample test performance data is as in showing.
