Abstract
The invention relates to adhesive resin with antiseptic function for steel pipe, which is prepared by HDPE, LLDPE, LDPE, PP, maleic anhydride, initiator, EVA, tackifier, antioxidant, color filler, and structural modifying agent with double-screws extruder. The product has high joint strength, and friend environment.
Description
Technical field
The present invention relates to a kind of industrial chemicals, particularly a kind of bonding steel pipe also has the adhering resin of anti-corrosion function.Belong to the binding agent field.
Technical background
It is anticorrosion that anti-corrosion pipeline in the past adopts pitch, coal tar enamel and fusion bonded epoxy resin that the cleaning steel tube surface is carried out more, is restricted owing to high pollution, non-refractory and paint film are thin and crisp.Adopt two-layer PE or three layers of PE anti-corrosive steel tube structure to cover the shortage at present mostly.But, because the bonding force of PE anti-corrosive steel tube is low, and poisonous, brought hidden danger to application.U.S. Pat 3798118A has proposed with addings such as ester gum and paraffin dystectic polypropylene preparation adding seam agent and caking agent, but can't be used for the bonding and anticorrosion of steel pipe.Chinese patent 86107790A has proposed to utilize processes such as modified random acrylic resin and resin of tackification to heat to be mixed with in the reactor that has constant speed low-shearing power whipping appts and has formed, it is bonding to be used for steel pipe, but from its technology and index, be not suitable for extruding the coating processes working condition, also be not suitable for the outdoor use of long term high temperature.Especially, buried steel pipe requires very strict to Corrosion Protection, and is very high to the bonding strength and the antiseptic power requirement of caking agent.
Summary of the invention
The objective of the invention is to obtain a kind of bonding strength height, use technology good, the bonding steel pipe of antiseptic property excellence also has the adhering resin of anti-corrosion function.
Buried steel pipe requires very strict to Corrosion Protection, requirement reaches the DIN30.670 standard, the present invention adopts polyolefine to develop the anticorrosion polymer bonding resin of using of buried steel pipe as material of main part, adopt parallel dual-screw extruding machine reactive extrusion technology under 220-300 ℃ of condition, on apolar substance, introduce polar group (as maleic anhydride), increase the bonding force of adhering resin, improve the polymer bonding resin flow by adding oxidic polyethylene or oxidation polypropylene in addition, improve and use processing performance.Make the polymer bonding resin have following characteristics: the bonding strength height, use technology good, the antiseptic property excellence is a kind of environment-friendly material.
The object of the present invention is achieved like this: the inventor is surprised to find with following proportioning and the excellent anticorrosion polymer bonding resin of using of preparation method's available energy,
Wherein, proportioning is specific as follows:
HDPE (high density polyethylene(HDPE)), LLDPE (linear low density polyethylene), LDPE (new LDPE (film grade)), PP (polypropylene) 48-67%
Maleic anhydride 0.5-10%
Initiator 0.01-0.5%
EVA (ethylene-vinyl acetate copolymer) 28-39%
Tackifier 5-20%
Softening agent 0.1-0.9%
Oxidation inhibitor 0.1-1.2%
Color stuffing 0.05-1.0%
Structural adjustment agent 0.05-0.3%
Above-mentioned initiator is meant: one or more of dicumyl peroxide (DCP), benzoyl peroxide (BP), ditertiary butyl peroxide (DBP);
Above-mentioned tackifier are meant: one or more of Gum Rosin, terpine resin, polyisobutene, chlorinatedpolyethylene, chlorosulfonated polyethylene, SIS, SBS;
Above-mentioned softening agent is meant: oxidic polyethylene and its chlorinated polypropylene;
Above-mentioned oxidation inhibitor is commonly used: antioxidant 1010 and oxidation inhibitor 168;
Above-mentioned structural adjustment agent is meant: stearylamide, N-Methyl pyrrolidone, caprolactam, to one or more of sulfonyloxy methyl amine, tetramethylene sulfone, dimethyl sulfoxide (DMSO).
Said components is utilized the preparation of cocurrent and parallel exhaust double screw rod extruder.
Advantage and effect
1. good bonding strength;
2. technical scheme is good;
3. the antiseptic property height reaches the DIN30.670 standard.
2. belong to environment-friendly material.
Embodiment
