Description
Technical field
The present invention relates to a kind of base coat and preparation method thereof, particularly bridge cable protective polyethylene priming paint and preparation method thereof, at polyethylene surface coating finish fluorocarbon coating.
Background technology
As sheath, polyethylene itself needs protection to polyethylene (English name Polyethylene is called for short PE).Polyethylene is usually used as cable rope jacket, especially for bridge cable sheath.Bear alternate load when polyethylene and be exposed in physical environment; drench with rain through exposing to the weather; particularly at serious regional, water pollutions seriously area, strand and the ocean environment of topsoil; polyethylene cannula there will be the phenomenon such as breakage, cracking; finally cause cable to damage, have a strong impact on protected cable performance and used life.
Polyethylene belongs to difficult sticky high molecular polymer.Polyethylene is by the straight chain of the methylene radical Structure composing of high degree of symmetry, has very high-crystallinity and orientation degree, shows as higher force performance on the one hand, and show as outstanding unreactiveness on the other hand, the ability in conjunction with coating matrix is low, has difficult cementability.The difficult cementability of polyethylene is caused by many reasons, and mainly comprise: without any polar group in molecular structure, the surface of coating (sizing agent) can only form more weak Van der Waals force by dispersion interaction; Polyethylene crystallinity is higher, and chemical stability is high, is difficult to form intermolecular winding by surperficial swelling and sizing agent; There is weak boundary layer in polyethylene; Polyethylene surface can be low, causes a lot of coating cannot soak its surface.Directly can not there is the phase mutual diffusion of high-polymer molecular chain, entanglement and combination with vinyon surface in fluorocarbon coating.The maintenance intervals of protected cable can be extended at pe sheath coated with fluoro carbon coating.The fluorocarbon coating adhesion property of direct application polyethylene surface is poor.
At present, when polyethylene surface coating finish fluorocarbon coating, use the heat-resisting priming paint of organosilicon.Silicone resin, aminoresin, high-temperature resisting pigment, pigment extender, rust-stabilising pigment, softening agent, special addition agent are mixed into mixture after mechanical mill is qualified.Dilute described mixture by dimethylbenzene, N-BUTYL ACETATE and prepare the heat-resisting priming paint of organosilicon.The heat-resisting priming paint of organosilicon can form hydrogen bond with the group of polyethylene substrate surface and be condensed into-SIO-M covalent linkage (M is substrate surface).The interface interaction power of hydrogen bond and covalent linkage is higher than Van der Waals gravitation, and between siloxanes and base material, interface generic key energy is greater than physical adsorption energy, has certain sticking power to basic interface.The polyethylene adhesion property of attachment organic-silicon heat-resisting paint film increases.But organic-silicon heat-resisting paint film still can not be attached to polyethylene surface securely, easily comes off.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of priming paint being firmly attached to polyethylene surface, strengthens finish paint fluorocarbon coating at the sticking power of polyethylene surface, makes finish paint fluorocarbon coating be bonded at polyethylene surface securely, not easy to foaming and incrust.
Bridge cable protective polyethylene priming paint of the present invention, is made up according to weight proportion stirring of following raw materials according: dimethylbenzene 120 ~ 160 parts, trimethylbenzene 10 ~ 30 parts, Chlorinated Polypropylene III 10 ~ 30 parts, chlorinatedpolyethylene 10 ~ 20 parts, acrylic resin 0.5 ~ 2 part, fluorochemical surfactant 0.1 ~ 0.5 part, defoamer 0.1 ~ 0.5 part.
Preferably, bridge cable protective polyethylene priming paint of the present invention, is made up according to weight proportion stirring of following raw materials according: dimethylbenzene 140 parts, trimethylbenzene 10 parts, Chlorinated Polypropylene III 25 parts, chlorinatedpolyethylene 16 parts, acrylic resin 1 part, fluorochemical surfactant 0.1 part, defoamer 0.25 part.
Preferably, bridge cable protective polyethylene priming paint of the present invention, is made up according to weight proportion stirring of following raw materials according: dimethylbenzene 130 parts, trimethylbenzene 20 parts, Chlorinated Polypropylene III 28 parts, chlorinatedpolyethylene 14 parts, acrylic resin 1 part, fluorochemical surfactant 0.2 part, defoamer 0.3 part.
Preferably, described fluorochemical surfactant is perfluoro octyl sulfonic acid potassium or N-ethylperfluoro octyl group sulphonamide.
Preferably, described defoamer is organo-siloxane defoamer.
Preferably, described organo-siloxane defoamer is Siloxane-Oxyalkylene Copolymers defoamer or polydimethylsiloxane defoamer.
A kind of making method of producing bridge cable protective polyethylene priming paint of the present invention is as follows:
(1) in stirring and dissolving still, add all solvent xylenes and trimethylbenzene in proportion, stir;
(2), when being warming up to 45 DEG C-50 DEG C, Chlorinated Polypropylene III, chlorinatedpolyethylene and acrylic resin is added;
(3) after said mixture dissolves, add fluorochemical surfactant and defoamer, continue stirring 20 minutes to 30 minutes;
(4) said mixture is filtered through 100 eye mesh screens, obtain base coat.
Dimethylbenzene and trimethylbenzene stirring at normal temperature are evenly configured to diluting solvent.Dimethylbenzene has rapid solution performance to Chlorinated Polypropylene III and chlorinatedpolyethylene.High boiling trimethylbenzene plays the effect of film coalescence aid, to construct under envrionment temperature widely.
Chlorinated Polypropylene III and chlorinatedpolyethylene are as filmogen.Independent employing chlorinatedpolyethylene has stings end phenomenon, and sticking power is not as Chlorinated Polypropylene III, thus select Chlorinated Polypropylene III and chlorinatedpolyethylene composite as filmogen.Chlorinated Polypropylene III and diluting solvent obtain solution.When directly adding, normal temperature and when not stirring, Chlorinated Polypropylene III can be dissolved completely in diluting solvent in 24 hours; Heating and stirring can be accelerated to dissolve, and can dissolve completely in the fastest half an hour.
Acrylic resin, fluorochemical surfactant, defoamer are joined in the solution of the preceding paragraph description in the ratio of formula, stirs, obtain priming paint.Fluorochemical surfactant is mainly used to strengthen the sticking power between priming paint and base material, fluorine-containing finish paint; Defoamer be used for eliminate fluorochemical surfactant produce a large amount of foams so that construction and obtain smooth film.
When using priming paint of the present invention, after priming paint of the present invention is mixed according to weight ratio 1:2 with thinner, stir at normal temperatures, directly use after dilution.Normal temperature is brushed or roller application, controls coating thickness about 20 μm, and half an hour can surface drying, then can carry out secondary application.
The Chlorinated Polypropylene III of priming paint of the present invention introduces the chlorine atom of strong polarity, and wherein again containing nonpolar carbochain, thus have good consistency with polyethylene, its strong polarity has good bonding force with finish paint fluorocarbon coating again simultaneously.
The invention has the beneficial effects as follows:
Base coat of the present invention plays the effect of binding agent between polyethylene film and finish paint, makes F-C paint film be bonded at polyethylene surface securely, not easy to foaming and incrust, and real plays protection polyethylene effect.
Priming paint of the present invention can improve the characteristic of polyethylene surface, as cementability, printing and hot weld.
