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, apply to one kind of steel pipe external layer preservation
3pp pipeline corrosion protection adhesive.
Background technology
It has been the common approach of industrial employing at this stage, e.g., stone using the long-distance conveying that metallic conduit carries out resource
Oily conveying, natural gas transportation, for heated conveying, supplying water conveys etc..In the long-distance conveying of pipeline, the protection to metallic conduit is
Particularly important.Because there being longer metallic conduit to be life settlement, some locations or even the environment being embedded in away from people
Situation very severe.Therefore, people can carry out protection in power to metallic conduit, and wherein, anti-corrosion is an important ring.Mesh
Before, China mainly adopts 3pe(3 Rotating fields polyethylene coating to the anti-corrosion of long-distance transport pipes) or the painting of 3pp(3 Rotating fields polypropylene
Layer) corrosion-inhibiting coating technology.In general, not higher than 70 DEG C of the use temperature of 3pe corrosion-inhibiting coating, and the making of 3pp corrosion-inhibiting coating
Can be higher than 70 DEG C with temperature, but be usually no more than 90 DEG C.Too high can make the 3 of epoxy powder/adhesive/jacket material using temperature
Declining occurs in the adhesion of coating systems, and makes corrosion-inhibiting coating (system) premature failure.Thus it is guaranteed that the adhesive in 3pp is in high temperature
In using effect, have highly important effect to stablizing of whole 3pp protective system.
