Abstract
The invention discloses a 80-degree anticorrosion hot melt adhesive which comprises the following materials in percentage by weight: 56-68 percent of ethylene acrylic acid maleic anhydride terpolymer (EMH), 7-10 percent of terpene, 11-15 percent of C5 petroleum resin, 2-10 percent of calcium carbonate, 7-10 percent of glyceride, 1-3 percent of antioxidant and 1-3 percent of carbon black. A preparation method of the 80-degree anticorrosion hot melt adhesive comprises the following steps of: weighing all component materials based on a prescription; mixing and milling all the materials in an open mill for 90-120 min with the mixing and milling temperature controlled to be below 200 DEG C; and coating adhesive and forming. Because of the adoption of a novel prescription, the hot melt adhesive not only has higher bond strength, but also greatly improves the excellent peel strength under a high temperature working environment, and can completely meet the requirement of a bonding agent for steel pipe corrosion at the temperature of 80 DEG C.
Description
Technical field:
The present invention relates to a kind of steel pipe and use hot melt adhesive, particularly a kind of 80 the degree hot conditionss under the anticorrosion bonding of steel pipe welded junction part with hot melt adhesive and preparation method thereof.
Background technology:
Pipeline transportation plays an increasingly important role in the middle of industrial gas oil and even national economy as the important step that connects production of hydrocarbons and market.Because steel pipe is long-term embedding underground, can receive a series of oxidation, destruction and corrosion such as soil, underground water, air, root system of plant, so the anticorrosion of steel pipe is to prolong the buried pipeline important means in work-ing life.After U.S. Republic-steel company invention fifties Vilaterm coated the steel pipe technology for external corrosion-proofing, this technology was able to improve and try out in many countries.But the past is that two-layer structure is anticorrosion basically, and promptly bottom is a hot melt adhesive, and surface layer is the Vilaterm coating layer.The G.Gaillard of back France etc. has adopted three layers of anticorrosion structure, bottom to adopt hot melting cohesion epoxy resin, and the middle layer is a hot melt adhesive, and surface layer is a polyolefine.Because the adhesive property of epoxy coat and steel pipe is good, and has antiseptic power, has improved the antiseptic property of whole system greatly, makes that this technology is able to apply widely abroad.
The initial stage eighties; China buries that ground oil, feed channel are anticorrosion to begin to adopt Vilaterm (PE) Cladding Steel Manifold technology; Because it has remarkable antiseptic property; Anti-water vapor or moisture vapor transmission ability are strong, physics, chemicalstability are good, and anticorrosion process is continuous, economical rationality and replaced the pitch woven fiber glass aseptic technic that in the past adopted rapidly.But traditional hot melt adhesive generally is to be made up of thermoplastic material, and is thermo-labile, is soluble in organic solvent, and cohesive strength neither be very high, therefore, mainly is applicable at present to need not heat-resisting and the less demanding occasion of cohesive strength.But under the different environment temperature; Thermotolerance to hot melt adhesive has different requirement, especially in desert Environment or the higher region of other surrounding temperature, daytime scorching temperature; Require hot melt adhesive can at high temperature have good adhesive property, high thermal resistance is good.Therefore developing one type has high thermal resistance, has good adhesive property under the high temperature, and the high-temperature anticorrosion hot melt adhesive that has between suitable softened zone is the task of top priority.
Summary of the invention:
For solve the hot melt adhesive that prior art exists thermo-labile, be soluble in organic solvent, the deficiency that cohesive strength is low, the present invention provides a kind of 80 degree antiseptic hot melt glues and preparation method thereof, can be in 80 degree high temperature uses down, cohesive strength is good.
The invention discloses a kind of 80 the degree antiseptic hot melt glues by following material by weight percentage content form:
Ethylene-acrylate maleic anhydride terpolymer (EMH) 56-68%
Terpenes 7-10%
C 5 petroleum resin 11-15%
Lime carbonate 2-10%
Glyceryl ester 7-10%
Inhibitor 1-3%
Carbon black 1-3%.
Described C 5 petroleum resin, 95～120 ℃ of softening temperatures.Described inhibitor is four (β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester.
High-temp.-resistant hot-melt adhesive process for making of the present invention is following:
1. the preparation of material: take by weighing the each component material by prescription;
2. mixing: with all materials mixing 90～120min in mill, melting temperature is controlled at below 200 ℃;
3. be coated with gum forming.
The technical feature of hot melt adhesive of the present invention is following:
1. temperature (T
f): 145 ℃;
2. viscosity: 2000-4000 moors
3. color: black;
4. no various peculiar smell in working.
Beneficial effect:
1. hot melt adhesive of the present invention is because the new formulation that adopts; Not only has higher bonding strength; And improved product hot melt adhesive good stripping strength under the pyritous Working environment widely, can satisfy the requirement of sticker in the steel pipeline anti-corrision under 80 degrees celsius fully;
2. the present invention has adopted the blend preparation technology of simple actual effect, customer service hot melt adhesive chemical prepn process in the past need this difficulty of complex engineering, technological process is simplified greatly, energy consumption reduces, and has good economic benefits and suitability for industrialized production prospect;
3. material source of the present invention is extensive, easy to process, and production technique is quick, and productivity is high, and construction is succinct, and product is solvent-free, and environment is not polluted, and has good stability to aging and resistance to air loss;
4. shelf life of products of the present invention and long service life, acid-and base-resisting, salts solution excellent performance are compared with like products the adhesive property of priming paint and PE and to be had very strong meliority.
The invention provides a kind of is Hotmelt Adhesive of master and preparation method thereof with ethylene-acrylate maleic anhydride terpolymer (EMH).Raw material in the existing method is selected and is carried out modification, the adhesive property of product and toughness are further enhanced, obtain a kind of narrow fusion range, high softening-point, toughness well, the tackiness agent of good stripping strength arranged under the hot conditions.
