Description

A kind of modifying asphalt and preparation method thereof
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 etc. 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 have not airtight pore, pin hole existence, to making antiseptic property can not expire 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: contain oxidized bitumen, Atactic Polypropelene, regenerated rubber, short glass fiber, crosslinking coagent, oxidation inhibitor, stearic acid (or oleic acid), organo-peroxide, talcum powder, clorafin.Wherein the weight of each component has proportion by subtraction to be:
Component weight %
Oxidized bitumen 30～80%

The preparation method of a kind of modifying asphalt (the present invention), it is characterized in that: with penetration degree is that 10～80 oxidized bitumen is crushed into the fragments that weight is no more than 1000 grams, putting into asphalt heating pot boils, heating and temperature control is about 230～240 ℃, insulation is at 180～230 ℃ after pitch melts fully, and carried out stir about 60～120 minutes with 150～200 rev/mins speed, will handle and the short glass fiber of oven dry add in batches through coupling agent solution then.Treat its scatter after with liquid state 1,2-polyhutadiene or divinylbenzene add mixing as crosslinking coagent.Add Atactic Polypropelene again, melt fully, when mixing, will contain in the fluid drips adding said mixture of organic superoxide, make sheet material with the talcum powder demoulding then at the above-mentioned component (except that glass fibre) of dosing.When being cooled to 60～80 ℃ and regenerated rubber (being cut into fragment) mixing.And add talcum powder, oxidation inhibitor, the chlorinated paraffin that stearic acid or oleic acid were handled.Mixingly add the talcum powder demoulding after evenly again and talcum powder is made the sheet material of 5～15 mm thick as separant, coil the back deposit.
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 (the methacrylic acid third nitrotrimethylolmethane methoxy silane), 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 ' functionality organic group of the silane molecule the other end can react with the organic group in the modifying asphalt, 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 material.
