Wonderfully by above two composition according to weight ratio (1-3):The product that (2-4) is fully blended can admirably achieve this hair
Bright technique effect and purpose obtains the more excellent performances such as water-fast, corrosion-resistant.
(5) coupling agent：Epoxy silane coupling KH-560 is most common coupling agent in coating system, is most being started
Experiment in, separately as the present invention coupling agent be difficult to improve compatibility and interface characteristics, the finished product prepared between raw material
Coating property is bad, and then, application people have been surprisingly found that is contained in anti-settling Aluminate ASA can be with active hydrogen reaction
Group can occur bonding action with the inorganic filler in this coating system, can substantially improve red halloysite, periclase powder, ultra-fine six
The compatibility and binding force of square boron nitride nanometer granular filler and acrylic resin and furane resins, coordinated rare-earth coupling agent
According to weight ratio (1-3):(3-5):(1-2) is blended, and is not only stablized the coating system of the present invention, is reached result of prevention, may be used also
Improve the adhesive strength of coating system.
(6) agitator tank rotating speed：The final speed of agitator of coating system of the present invention is worthy of careful study, optimum interval 500-
700r/min, is less than the rotating speed section, and reaction is insufficient, it is difficult to embody the advantageous effect of finished product coating；Higher than the rotating speed section,
Production cost will be increased, or even cause reduction or the missing of comprehensive performance.
Certainly, because of the requirement of the mentality of designing and goal of the invention of coating of the present invention, remaining of the invention component selection and contain
Amount selection is obviously also non-obvious, and those skilled in the art combine the prior art that can readily occur in absolutely not.This is at this
Have further embodiment in terms of the preparation method of invention coating, in conjunction with the embodiment of the present invention it can be seen that, preparation of the invention
Method uses four steps to design, and raw material is added by several times in batches, and step is simple and orderly, rather than using the one of prior art routine
(such as comparative example 5) is added in secondary property, and this preparation process is adapted with the special proportioning of coating components of the present invention, only with adopting
With this technique, it just can guarantee that the smooth sequential of reaction system carries out, ensure the superiority for the coating property finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although with reference to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution recorded in example is modified or equivalent replacement of some of the technical features.All essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
