Abstract
The invention relates to an oxidation-resistant coating composition. The oxidation-resistant coating composition comprises various resins and auxiliaries and is highly resistant to ultraviolet irradiation and temperature difference change by means of combination of all the components.
Description
Technical field
The present invention relates to a kind of antioxidant coating composition.
Background technology
Along with national economy and high-tech development, to the requirement of coating except universal, day by day urgent to the demand of speciality coating.In numerous functional paint; insulation antioxidant coating is a kind of important functional paint; its effect is to various factors, and the object temperature that particularly in external environment, the uv-radiation of sunlight causes changes and oxidation is controlled, and has to object the oxidation protection effect that relents.Still there is many problems in temperature control effect and the oxidation-resistance of current existing insulation antioxidant coating, still needs to continue to improve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of antioxidant coating composition, employing resin and the auxiliary agent of number of different types in this coating composition, the combination of each component makes it have the performance of good ultraviolet radiation resisting, resistance to difference variation.
It is as follows that the present invention solves the problems of the technologies described above adopted technical scheme:
A kind of antioxidant coating composition, this coating composition is prepared by following following steps, and each raw material is all with weight parts:
A) remove ionized water 50 parts, Styrene-acrylic copolymer emulsion 15 parts, fluoro-resin 8 parts, Synolac 10 parts, diphenylethyllene phenol Soxylat A 25-7 3 parts, mixing add in reactor, with the speed dispersed with stirring 30 minutes of 500 revs/min;
B) take ethylene glycol monomethyl ether 5 parts respectively, glycerol glycerinate 5 parts, dispersion agent 2 parts, adds in reactor successively, dispersed with stirring 30 minutes under the speed of 700 revs/min;
C) continue to improve rotating speed to 800 rev/min, add organic fluorinated silicone resin 10 parts, acrylic resin 10 parts, butyl carbitol 2 parts, polyprenol 1 part successively, fully stir 30 minutes;
D) rotating speed is adjusted to 900 revs/min, add silane coupling agent NQ-72 2 parts, cobalt blue 5 parts, aluminum oxide powder 5 parts, silica powder 5 parts, uvioresistant additive 3 parts, paraffin microcapsule 5 parts, dispersion agent 1 part, defoamer 1 part successively, uniform stirring is about 30-60 minute;
E) mixture is fully ground 1 hour in shredder, after filtration, obtain antioxidant coating composition;
Described acrylic resin is adopted and is prepared with the following method: with weight parts, get 30 parts of ethanol, 15 parts of isopropyl acetates, add after mixing in reactor, with the ramp to 80 DEG C of 10 DEG C/min, insulation 30min, then add 20 parts of methyl acrylates, 10 parts of methacrylic acids, 10 parts of Hydroxyethyl acrylates, 2 parts of diacetone acrylamides, 1 part of azo dicyclohexyl formonitrile HCN successively, be uniformly mixed, isothermal reaction 5 hours, is cooled to 30 DEG C, drips 1.0ml ammoniacal liquor, stir 20min again, obtain acrylic resin.
Described defoamer is BYK-014.
Identical dispersion agent is used in described step b) and step d).
beneficial effect
The combination of various kinds of resin and auxiliary agent is have employed in coating composition of the present invention, such as Synolac the modification tack of coating, water tolerance, acrylic resin improves the temperature-change resistance of coating, the ultraviolet component of multiple absorption is comprised in coating, the interphase interaction of each component, makes coating composition have excellent ultraviolet radiation resisting and the performance of resistance to difference variation.
