Abstract
The invention relates to a heavy anti-corrosion clinkery epoxy powder coating, which comprises the following components in part by weight: 100 parts of epoxy resin, 20 to 30 parts of curing agent, 2 to 5 parts of flatting agent and 40 to 70 parts of filler. The heavy anti-corrosion clinkery epoxy powder coating is mainly applied in the field of pipeline corrosion prevention and has the advantages of high toughness, high impact resistance, simple preparation process and suitability for mass production.
Description
Technical field
The present invention relates to pipeline corrosion protection clinkery epoxy powder coating technical field, be specifically related to a kind of heavy anti-corrosion clinkery epoxy powder coating.
Background technology
Heavy anti-corrosion clinkery epoxy powder coating, claim clinkery epoxy powder coating (FBE) again, be a kind of be that carrier transports and dispersed solids coating with the air, it is coated on the surface of steel workpiece of preheating, fusing, levelling, solidify to form uniform coating, English name is FBE.It is mainly used in pipeline corrosion protection, be a kind ofly do not contain solvent, with the film forming new anti-corrosion coating of powder melts, in the pipeline coating procedure, do not exist VOC to pollute, curing speed is fast, long service life.At that time because the condition harshness of natural gas line construction by land, circumstance complication, higher to chemical property, mechanical and physical performance and the spraying application performance demands thereof of heavy anti-corrosion clinkery epoxy powder coating, the especially shock resistance of FBE, snappiness.
Existing FBE coating material production generally adopts and is solid-state bisphenol A epoxide resin or epoxy Dyhard RU 100 powder coating under the room temperature, exist shortcomings such as degree of crosslinking is low, levelling property difference, contradiction after also existing film forming to solidify between hardness and shock resistance, the snappiness, though so at present done a few thing aspect toughness reinforcing at clinkery epoxy powder coating, but be cost with expendable material intensity, modulus and thermotolerance usually, make its physics, mechanics and thermal characteristics be subjected to very big influence, even take into account the problems referred to above, toughening effect is also not obvious.
Summary of the invention
The technical problem that the present invention solves is to overcome the above-mentioned deficiency of prior art, and a kind of shock resistance height, heavy anti-corrosion clinkery epoxy powder coating that flexility is good are provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of heavy anti-corrosion clinkery epoxy powder coating, form by the component of following parts by weight: Resins, epoxy 100 weight parts, solidifying agent 20～30 weight parts, flow agent 2～5 weight parts, filler 40～70 weight parts.
Above-mentioned Resins, epoxy is that weight ratio is 0.3～3: 1 novolac epoxy resin and the mixture of Resins, epoxy E-12.
Above-mentioned solidifying agent is JECP-02B or JECP-02B solidifying agent.
Above-mentioned flow agent is the polyacrylate flow agent of GLP588 silicon-dioxide absorption or the polyacrylate flow agent of the ultra-fine high dispersive silicon-dioxide absorption of GLP788.
Above-mentioned filler is that weight ratio is active micro silicon powder, mica powder, gas-phase silica, process white=15: 7.5: 1: 40 mixture.
Advantage of the present invention: E-12 Resins, epoxy is typical base-material, existing bisphenol-A phenolic composition has phenol phenolic aldehyde composition again in the linear phenolic epoxy resin molecule, there are a plurality of epoxide groups in the molecule, have that degree of crosslinking height, hardness of film height, wear resistance are good, the characteristics of favorable anti-corrosion effect; The adding of solidifying agent can make the molecule crosslinked macromole that reticulates structure of linear loop epoxy resins, thereby shows the inherent premium properties; Add flow agent and can improve appearance of coat, enhanced flow levelling; The tenacity of powder coating of the present invention, coating good toughness, shock resistance height can satisfy the requirement for anticorrosion of buried pipeline, and technology is simple, is suitable for scale production, and other performances meet SY/T 0315-97 index request.
