Abstract

The invention relates to the technical field of corrosion of repaired mouths of engineering and petroleum pipelines, in particular to a hot-melt adhesive for preventing the corrosion of a repaired mouth of a pipeline. The hot-melt adhesive comprises the following components in percentage by weight: 30 to 70 percent of epoxidized SBS (styrene-butadiene-styrene) resin, 5 to 40 percent of vinyl copolymer, 5 to 40 percent of rubber elastomer, 5 to 40 percent of tackifying resin, 5 to 20 percent of inorganic filler and 1 to 8 percent of aid; and the hot-melt adhesive is prepared by performing melt blending on the components by using an intensive shear banbury, and performing extrusion granulation by using a twin-screw extruder. The hot-melt adhesive for preventing the corrosion of the repaired mouth of the pipeline, which is prepared from the epoxidized SBS resin serving as a base material, solves the problem that the conventional hot-melt adhesive has insufficient toughness and brittle failure at low temperature and low peel strength at high temperature. The hot-melt adhesive has high toughness at low temperature and high peel strength at high temperature, hardly falls off or allows water to enter the pipeline in the long-term running process, is convenient to construct in field, has excellent bonding property and ensures reliable bonding.

Description

The joint coating on pipeline antiseptic hot melt glue
Technical field
The present invention relates to engineering, petroleum pipe line preventing corrosion of repaired mouth technical field, particularly joint coating on pipeline antiseptic hot melt glue.
Background technology
The long distance oil-gas pipeline transportation, it is the 5th big mode of transport after highway, railway, water route, air transportation, effect in the middle of industrial gas oil and even world economy becomes increasingly conspicuous, for inflammable, explosive, volatile oil and gas, best mode of transport is exactly the closed pipeline transportation.
The corrosion-resistanting interpolating port construction is the important procedure of long distance pipeline site operation, also is the link that easily goes wrong in the construction.Existing repaired mouth mode has multiple modes such as petroleum pitch repaired mouth, epoxide coal bituminous repaired mouth, adhesive tape repaired mouth, epoxy primer repaired mouth and PE material contracting with heat repaired mouth.At present, the pipeline corrosion protection pyrocondensation product with three layers of corrosionproof protection function is mainly used in domestic and international great pipework, and product is made up of three parts such as radiation crosslinking pyrocondensation belt, hot melt adhesive, double component solvent-free type epoxy primers.Wherein hot melt adhesive mainly is the material of main part preparation with EVA, its low-temperature flexibility is poor, the high temperature stripping strength is low, interfacial failure normally when peeling off, poor to high density polyethylene(HDPE), surface drying epoxy primer adhesiveproperties, in the long-time running process, occur easily coming off, intaking causes corrosive pipeline, make that pipeline is whole anticorrosionly falls short of success for lack of final effort, not only economy sustains a loss, and exists Serious Accident hidden danger.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of when low temperature good toughness, the stripping strength height during high temperature, in the long-time running process, be not prone to and come off, intake, site operation is convenient, adhesiveproperties excellence, bonding reliable joint coating on pipeline antiseptic hot melt glue.
Solution of the present invention is: a kind of joint coating on pipeline antiseptic hot melt glue is characterized in that the each component weight percent is as follows:
Epoxidized SBS (styrene-butadiene-styrene block copolymer) resin 30-70%;
Vinyl copolymerization 5-40%;
Rubber-like elastomerics 5-40%;
Tackifying resin 5-40%;
Mineral filler 5-20%;
Auxiliary agent 1-8%;
Each component is by shearing the Banbury mixer melt blending by force, preparing through double-screw extruding pelletizing.
Auxiliary agent comprises coupling agent, colorant, oxidation inhibitor in the solution of the present invention.Coupling agent can adopt titanic acid ester or aluminic acid ester or silane or tensio-active agent or lipid acid, and the coupling agent consumption is the 0.5-2% of mineral filler.Colorant can adopt high-melt index to make the Masterbatch or the carbon black powder of carrier, and the colorant consumption is the 1-5% of material total amount.Oxidation inhibitor can adopt Hinered phenols or monothioester class or composite antioxidant class, and the oxidation inhibitor consumption is the 0.5-3% of material total amount.
Ethylenic copolymer can adopt EVA (ethylene vinyl acetate copolymer) or EBA (ethylene butyl acrylate multipolymer) or EMA (ethylene methyl acrylate copolymer) or EAA (ethylene acrylic acid co polymer) in the solution of the present invention.
The rubber-like elastomerics can adopt isoprene-isobutylene rubber or silicon rubber or SIS (styrene-isoprene-styrene copolymer-) or EPDM (terpolymer EP rubber) in the solution of the present invention.
Tackifying resin can adopt its derivative of terpine resin or rosin and derivative or petroleum resin or naphthenic oil in the solution of the present invention.
Mineral filler can be adopted lime carbonate or talcum powder or white carbon black in the solution of the present invention.
Advantage of the present invention: the present invention solves existing hot melt adhesive toughness deficiency when low temperature, brittle rupture, the problem that the stripping strength during high temperature is low with the pipeline corrosion protection repaired mouth hot melt adhesive of epoxidized SBS as the base mateiral preparation.Good toughness during low temperature of the present invention, the stripping strength height during high temperature is not prone in the long-time running process and comes off, intakes, and site operation is convenient, and the adhesiveproperties excellence is bonding reliable.
Embodiment
Embodiment 1: take by weighing epoxidized SBS resin 8kg respectively, EVA (28/400) 2.4kg, SIS elastomerics 1.6kg, terpine resin 4kg, talcum powder 1.6kg, other auxiliary agents 0.4kg, 100 ℃ of mixing 20min dischargings down add twin screw extruder in Banbury mixer, and controlled temperature is at 100-140 ℃, extruding pelletization gets hot melt adhesive behind the cooling drying.
