Description

Modified asphaltum and its producing method
The present invention relates to a kind of machinery that can be used for and extrude modified asphalt material of clad metal pipeline and preparation method thereof.
At present, being used to bury the metallic conduit corrosion protection coating of ground oil transportation, gas, water pipe both at home and abroad, mainly is to adopt following material, as oxidized bitumen, coal tar enamel, tar epoxy, polyolefin resin, epoxy powder and sealing tape.For having the transport pipe that insulation requires, can be as the outer sheath material of pipe insulating layer generally have only polyolefin resin.Because above-mentioned impregnating material coating approaches shock resistance, weathering resistance is poor, or there are not airtight pore, pin hole to exist, to making antiseptic property can not satisfy technical requirements.The metallic conduit that development in recent years is got up " yellow jacket ", " black jacket " are affected its industrial application though have the over-all properties of corrosion-resistant thermal insulation preferably owing to it consumes a large amount of expensive chemical materialss.The novel impregnating material of external exploitation such as EP125852, US4404316, DE3203226, SU1174662, disclosed technology contents such as SU1062229, SU1116260 are still senior chemical materials or its finished product that occupy quite a lot of composition and belong to and are coated with application or wound form sealant tape material, as anti-corrosive thermal insulation material, still have and cost an arm and a leg or the defective of manufacturability difference.
The object of the present invention is to provide a kind of modifying asphalt and preparation method thereof.Its product can be used as the impregnating material that machinery is extruded the clad metal pipeline.Can be used for metallic conduit directly coats or coats on pipe insulating layer.Because adopting oxidized bitumen and regenerated rubber is main raw material, makes it to have cheap characteristics, has good antiseptic property, low temperature flexibility, characteristics such as advantages of higher tensile strength, anti-stress cracking.Have good mechanical agent simultaneously and go out covering property and higher softening temperature.Thereby overcome involving great expense and defective that prior art such as asphaltic base sheet material coating material complex process, poor reliability is brought of Huang (deceiving) jacket.Making the pipeline corrosion protection lagging material be used for machinery extrudes the technology that coats transport pipe and has wide prospect more.Modifying asphalt involved in the present invention is to add modified materials such as Atactic Polypropelene, regenerated rubber, short glass fiber, talcum powder, crosslinking coagent in oxidized bitumen, does not contain volatile organic solvent (can avoid the defective of the sealings such as pin hole that the volatilization because of volatile solvent causes).Do not changing under the preceding topic of the original Anticorrosive Character of oxidized bitumen, by physics, chemical modification.
A kind of modifying asphalt is characterized in that: formed through mixing or chemical combination by oxidized bitumen, Atactic Polypropelene, regenerated rubber, short glass fiber, crosslinking coagent, oxidation inhibitor, stearic acid (or oleic acid), organo-peroxide, talcum powder, clorafin each component.Wherein the weight percent of each component is:

Oxidized bitumen of the present invention can be the heavy oil that is obtained by normal decompression, through the oxidized bitumen that further air blowing oxidation makes, also can be low-sulfur paraffinic base oxidized bitumen, and its penetration degree is 10～80 in the time of 25 ℃.
Atactic Polypropelene of the present invention is for making polyacrylic byproduct.Limiting viscosity (135 ℃ time perhydronaphthalene solvent in) is about 1.6～1.9.
Crosslinking coagent of the present invention is monomer or the oligomer that contains the alkene of two keys more than two and two.As 1,2-polyhutadiene (number-average molecular weight is generally 2000～7000), or divinylbenzene.
Regenerated rubber of the present invention is a waste rubber goods, removes cord after mechanical disintegration makes as junked tire.
Short glass fiber of the present invention, its length is 5～15 millimeters, single fiber diameter is 8～13 microns, fiberglass surfacing is handled through silane coupling agent, this coupling agent can be A-174(r-methacryloxypropyl (base) propyl trimethoxy silicane), also can be A-1100(r-amine propyl-triethoxysilicane).After the silane coupling agent aqueous solution was coated on fiberglass surfacing, the OR base was hydrolyzed into the OH base in the aqueous solution.Also be that alkoxyl group is hydrolyzed into silanol.Itself and fiberglass surfacing hydrophilic radical react or condensation, produce chemical reaction, generate chemical bonding.And the R ' palace of the silane molecule the other end can be reacted with the organic group in the modifying asphalt by the property organic group, produces physics or chemical bonding.Therefore make the same oxidized bitumen of hydrophilic glass fibre, produce physics or chemical bonding by the silane coupling agent effect between the hydrophobes such as Atactic Polypropelene, rubber, thereby become compatible, improve the intensity and the anti-stress cracking ability of modifying asphalt.
Oxidation inhibitor of the present invention can be N-sec.-propyl-N '-phenyl-Ursol D, also can be 2,2,4-trimethylammonium-6-oxyethyl group-1,2-titanium dioxide quinoline.
