Abstract
Anticorrosive thermofusible adhesive for pipeline of the present invention belongs to the prescription and the manufacture craft of a kind of hotmelt in the thickness chemical materials; reinforced the limit is mixing forms 140-160 ℃ of bottoms with particle and powdery for the polymer that it is aggregated into by polyisobutene-isoprene monomer and tackifier, strengthening agent, oxidation inhibitor, polyolefine, thermoplastic elastomer, additive and filler, and the limit adds the particle that the talcum powder limit is a granulated into 6 * 15 in tablets press at last.Its technology is simple, good, shock-resistant, the anti-environment capacity of finished product binding property, sealing are lasting, have high-temperature stability and good insulation performance, and self-healing properties (creep properties) is arranged.
Description
The present invention relates to the prescription and the manufacture craft of a kind of hotmelt in the fine chemistry industry material, especially the steel tube surface rubber-type is extruded the prescription and the manufacture craft of glue-line.
Pipeline corrosion protection glue is commonly used, and to have with pitch be the hot melt adhesive of matrix, as bituminous epoxy, the epoxy coal, pitch-EVA(30), the polyolefine High-temp.-resistant hot-melt adhesive, their technology all be starting material under molten state, stirring then, discharging is cooled to finished product.It is poor that first three kind product exists with the metal tube cementability, meet water, surging force is easy to crack, disadvantages such as self-repairability difference, and construction when using labour intensity big, contaminate environment, in the time of can not satisfying on a large scale temperature variation, the requirement of steel pipe corrosion-proof, a kind of environmental stress that also exists in back is poor, easy to crack, bond strength is low, easily the aged disadvantage.
The purpose of this invention is to provide a kind of when temperature variation on a large scale, water tolerance.Shock-resistance, environmental stress crack resistance, ageing resistance and cementability be glue preferably all.
This hot melt adhesive is to be major ingredient with the rubber that aggregates under polyisobutene-isoprene monomer and the low temperature, (being called for short polymer molecule amount 45-60 ten thousand) is aided with tackifier, strengthening agent, thermoplastic elastomer (hereinafter to be referred as elastomerics) oxidation inhibitor, polyolefin additive, filler etc. in special mixing facilities, under vacuum condition, 160 ℃ of mixing forming.
Tackifier are Gum Rosins, aromatic hydrocarbons petroleum resin, terpine resin, beta-pinene resin, ancient marlon resin etc.
Strengthening agent has EEA, EVA etc.
Oxidation inhibitor is Hinered phenols antioxidant.
Thermoplastic elastomer is styrene-butadiene block copolymer (molecular weight 30-54 ten thousand).
Additive has titanic acid ester, epoxy silane, isocyanic ester etc.
Filler has (little 325 orders) such as talcum powder, lime carbonate, silica powders
A kind of anticorrosive thermofusible adhesive for pipeline, the percentage composition that it is characterized in that filling a prescription is polymer 3-60, tackifier 10-75, strengthening agent 1-40, elastomerics 0.5-10 polyolefine 0-10, additive 0.5-7, oxidation inhibitor 0.25-3, filler 5-45.
A kind of anticorrosive thermofusible adhesive for pipeline; it is characterized in that manufacture craft is to get the raw materials ready the back polymer in 140-160 ℃ the time mixing 1 hour; add polyolefine again; strengthening agent continued mixing 1 hour; add tackifier again, filler, mixing 1 hour of elastomerics; the limit adds the granulation of talcum powder limit in tablets press, and the particle of making Φ 6 * 15 gets final product.
According to above-mentioned prescription and the described anticorrosive thermofusible adhesive for pipeline of technology, it is characterized in that the work of getting the raw materials ready is that polymer is ground into the particle of Φ 3 * 4 or volume less than 0.5 centimetre
3Particle, tackifier are ground into less than 50 purpose powder, polyolefine is ground into less than 0.5 centimetre
3Particle, filler is dried moisture content is less than 0.5%, sneak in the filler baking again after additive is disperseed with spirit solvent then and remove alcohol, be chilled to room temperature.
The technical indicator of this hot melt adhesive is melt index MI0.1-1.5 gram/10 minutes, proportion 1-1.15 gram per centimeter Vicat softening point 〉=135 ± 10 degree, heat decomposition temperature 〉=250 degree, embrittlement temperature≤-54 degree, stripping strength 〉=3.5 kilograms per centimeter, shearing resistance＞0.35MPa.
Using method is wrapped in outside the tubing after being particulate state micelle hot melt sheet, wraps high-density polyethylene layer again and gets final product.
The invention has the advantages that technology is simple, finished product has excellent extrusion performance, good binding property, sealing persistence, withstand voltage, shock-resistant, bending property is excellent, high resilience has temperature tolerance preferably, weather resistance, high-temperature stable, low temperature is not crisp, and is corrosion-resistant, good insulating, be widely used, good manufacturability, granular sizing material, accumulating is convenient, certain creep properties is arranged, so self-healing properties deliquescing gradually below 200 ℃ fortunately, so, the pelleting property of excellence is arranged being hit or can repairing automatically during the small area damage.
Embodiments of the invention are to be undertaken by above-mentioned manufacture craft, and its mix proportion scheme is (%)
