Abstract
The present invention provides for a composition of high temperature resistant powder coating which comprises at least two silicone resins having different glass transition temperatures and/or different melt viscosities, a bi-functional resin, a mica-containing filler and optional additives. When applied to a substrate, the composition is capable of curing to form a high temperature resistant coating on the substrate surface. The present invention also provides for use of the composition of the present invention to coat a substrate, as well as substrates coated with the composition of the present invention.
Description
Technical field
The present invention relates to a kind of can solidification in substrate and produce the Heat Resistant Powder Coatings composition of high-temperaure coating.The invention further relates to and a kind ofly prepare the method for described composition and the purposes of described composition.
Background of invention
High thermal resistance is demonstrated for the coating significant need being applied to baking oven, boiler, heat exchanger, auto parts, culinary art assembly, cooker etc.Most of organic coating is not suitable for this application, because when being exposed to the air of temperature higher than 550 DEG C, they tend to be consumed fast.Result causes mixing the coating of polyorganosiloxane resin and the development of paint, as U.S. Patent number 5, described in 905,104 (people such as Eklund).Be referred to silicone resin mixture in an embodiment, i.e. the mixture of DowCorning1-0543 and DowCorningZ-6018.These resins have following characteristic:
-DowCorning1-0543 (being now DC220) T
g=49 DEG C, at 140 DEG C, viscosity is 9.8 pools;
-DowCorningZ-6018T
g=48 DEG C, at 140 DEG C, viscosity is 14.1 pools.
Although show the temperature tolerance of improvement, but still find that the coating comprising polyorganosiloxane resin at high temperature demonstrates deleterious effects.When the material applied by polysiloxane powder is exposed to the temperature higher than 550 DEG C, coating can lose its composition organic constituent by being oxidized; Result polyorganosiloxane resin rapid desufflation and produce stress in coating.This stress is eliminated by ftractureing, and causes coating peel off from material or peel off.
WO2004/076572 (DupontdeNemoursandCompany) is intended to shrink and softening and show the body material of certain fluidity in brittle temperature range at polyorganosiloxane resin by comprising at least one in polyorganosiloxane resin, preferred low melting point unorganic glass and head it off.
European patent number 0950695B1 (Morton) proposes a kind of possibility, and wherein powder paint compositions is made up of in conjunction with titanium dioxide and sheet mica and/or calcium metasilicate granular filler single silicone resin.The feature of single silicone resin is have siloxanes official energy (Si-O-H) and only have a small amount of organo moiety.The substitution value of preferred single polysiloxane is less than 1.5 and-OH content is 2.0-7.5 % by weight, based on the weight of described polysiloxane in the publication.When polysiloxane is at the temperature of 150-260 DEG C during self cure ,-OH containing quantitative limitation decrease water releasing and because this reducing in the coating because described water overflows the defect that causes as the formation of pin hole.But, should notice that this powder paint compositions only the build of 1.8-2.2 mil (45-55 μm) can be applied to substrate.
WO2009/003937 (AkzoNobelCoatingsInternationalB.V.) discloses a kind of powder paint compositions comprising resin Composition and filler, wherein resin Composition comprises the first silicone resin and the second silicone resin, its second-order transition temperature (T
g) difference at least 5 DEG C, and/or the differing melt viscosities at least 5 measured at 140 DEG C is moored, preferably 10 pools.About the filler component of described composition, preferred filler is the heat-stable material of a dimension than large at least four times of another dimension, and the amount that described filler is 5-95 % by weight with the weight based on resin Composition exists.Under finding that these compositions are in application to and can not tolerate when namely the substrate with high surfaceness has the substrate on coarse (profiled) or unfairness surface and be exposed to high temperature (~ 550 DEG C) for a long time.
When powder coating being applied to car body with protection and coating engineering product, substrate is tended to thinner and is had smooth-flat-surface.But, when coating being applied to requirement and demonstrating the material of high thermal resistance, more generally substrate surface is coarse or irregular: the steel for sandblast cleaning provides enough anticorrosion and (aesthetics) to cover with paint, lacquer, colour wash, etc., and such as this substrate must be coated with enough builds to make up surface irregularity degree.The uneven surface (wherein said profile can be defined by ISO8503) that substrate can produce " peak-paddy " distance that can present 10-80 μm is usually sprayed with the sponge of angle gravel, round shaped grain, load abrasive material or high pressure water note.
For this unfairness substrate, found the actual upper bound of the build (DFT) of powder coating, exceeding this upper limit coating from substrate cracking and will peel off.Obviously, this upper limit is lower, and the ability that given powder coating compensates the injection profile that substrate surface increases is lower.
Therefore there is a need in the field to provide one and demonstrate high thermal resistance, but also can be applied to rough base surface and provide the powder paint compositions of temperature tolerance and preferred preservative property for described surface.
Invention describes
The invention provides a kind of safety and free of contamination Heat Resistant Powder Coatings composition.When being applied to substrate, especially during rough base, described composition can solidify and form high-temperaure coating on the surface of the substrate.The present invention also provides the purposes of present composition coated substrate, and is coated with the substrate of the present composition.
