Abstract
The invention discloses an adhesive for corrosion prevention of a 3PP pipeline, which comprises the following raw materials in percentage by weight: 20-40% of nylon 1010, 10-20% of polycarbonate, 3-8% of a compatilizer A, 20-30% of a compatilizer B, 10-20% of bonding resin and 10-20% of toughening resin. The melt index of the nylon 1010 is 3.0-20.0g/10min; the melt index of polycarbonate is 3.0-20.0g/10min; the compatilizer A is styrene-maleic anhydride copolymer; the bonding resin is ethylene-acrylic acid copolymer; and the toughening resin is one of POE-g-MAH and SEBS-g-MAH or a mixture of the two. In the invention, the bonding resin in the 3PP system still can keep relatively high bonding strength at a temperature over 100 DEG C, the using effect of a 3PP coating at high temperature can be guaranteed, and the bonding resin plays an important role on the stability of the whole 3PP corrosion prevention system.
Description
Technical field
The present invention relates to industrial coating technical field, specifically, is that a kind of 3PP pipeline corrosion protection being applicable to steel pipe external layer preservation sticks with glue agent.
Background technology
The long-distance conveying utilizing metallic conduit to carry out resource has been the common approach of present stage industrial employing, e.g., and petroleum transport, natural gas transport, heat supply conveying, conveying etc. of supplying water.In the long-distance conveying of pipeline, be particularly important to the protection of metallic conduit.Because have longer metallic conduit to be embedded in the life dwell point away from people, some locations are even environmental aspect very severe.Therefore, people can carry out protection in power to metallic conduit, and wherein, anticorrosion is an important ring.At present, China mainly adopts 3PE(3 Rotating fields polyethylene coating to the anticorrosion of long-distance transport pipes) or 3PP(3 Rotating fields polypropylene coating) technology of corrosion protection coating.In general, the use temperature of 3PE corrosion protection coating is not higher than 70 DEG C, and the use temperature of 3PP corrosion protection coating higher than 70 DEG C, but can generally be no more than 90 DEG C.Too high use temperature can make the bonding force of 3 coating systems of epoxy powder/tackiness agent/jacket material occur declining, and makes corrosion protection coating (system) premature failure.Therefore, ensure the result of use of tackiness agent in high temperature in 3PP, have very important effect to the stable of whole 3PP protective system.
Chinese patent literature CN1317529 A discloses one " adhesive for coating on steel pipe "; Chinese patent literature CN1754932A discloses one " the polymer bonding resin and preparation method thereof for steel pipe corrosion-proof "; Chinese patent literature CN102533162A describes " a kind of preparation method of 3PE anti-corrosion pipeline PE hot melt adhesive powder ".But, above-mentioned patent documentation is all the hot melt adhesive prepared for resin that base-material is equipped with more low melting point with PE or PP, do not relate to the high temperature stripping performance improving product with high-melting-point polymer, do not relate to the consistency increasing product with styrene maleic anhydride copolymer (SMA) yet.
