Abstract
The invention provides white corundum micro powder filler for aircraft coating. The filler is redesigned on the basis of conventional white corundum micro powder according to the specific use environment of the aircraft coating, and the ratio of aluminum oxide is greatly lowered to improve the dispersibility of the corundum micro powder filler in the coating. Meanwhile, iron sesquioxide possibly influencing the color and luster of the coating is removed, and sodium oxide ingredients possibly influencing stability in a high-temperature state are removed. In addition, a specific quantity of kieselguhr ingredients is added in order to improve the adhesive force of the coating and the micro powder filler, and although the wear-resisting property of the coating is possibly influenced to a certain degree, the dilatation coefficient of the coating can be remarkably decreased. Meanwhile, due to the fact that the requirement of the use environment of the aircraft coating for the wear-resisting property is relatively low and the requirement for the high temperature resisting property is relatively high, the conventional ingredients of the white corundum micro powder are replaced with zirconium dioxide and silicon nitride, and the high temperature resisting property of the coating can be improved.
Description
Technical field
The present invention relates to technical field of ceramic material, be specifically related to a kind of white fused alumina micropowder filler for aeroplane dope.
Background technology
Along with the development of aerospace cause, demand and the use range of aeroplane dope are greatly expanded.Broad sense, all kinds of coating of aeroplane dope general reference on the flyers such as aircraft, and narrow sense mainly refers to for the coating under the unconventional environment such as aircraft skin, engine.Because environment for use is comparatively harsh, therefore aeroplane dope should have stronger weathering resistance in frictional force, temperature, acid and alkali corrosion, ionizing radiation etc., and this just determines the formula of aeroplane dope and preparation technology and common coating and there is larger difference.
In order to promote the wear resisting property of coating, the investigator of prior art attempts adding the mineral dusts such as silicate on the basis of common coating, and obtains certain success.In recent years, there is investigator that white fused alumina micro mist is used for the preparation of aeroplane dope, utilize white fused alumina micro mist wear-resisting, resistant to elevated temperatures characteristic that the weathering resistance of coating is obviously promoted.White fused alumina is that refine crystallization through electric smelting and form, purity is high, self-sharpening good, acid-alkali-corrosive-resisting, high temperature resistant, hot performance stablize, its hardness is a little more than Brown Alundum, and toughness is slightly low, and grinding capacity is strong with fine aluminum oxidation powder for raw material.The technologic materials such as grinding high carbon steel, rapid steel and stainless steel are mainly used in prior art; The preparation of precision casting and high grade refractory can also be used for.But not there is dispersiveness in a solvent due to white fused alumina micro mist, the problem of quality inequality is therefore easily there is with its coating prepared; In addition, after adding common white corundum powder, the sticking power of coating is subject to certain impact, although coat of paint its rigidity gets a promotion, even have coat of paint obscission to occur.
Summary of the invention
The present invention is intended to the technological deficiency for prior art, provides a kind of white fused alumina micropowder filler for aeroplane dope, when preparing aeroplane dope with common white corundum powder to solve in prior art, and the technical problem of coating quality inequality.
Another technical problem that the present invention will solve solves when preparing aeroplane dope with common white corundum powder in prior art, and coating reduces metal adhesion.
For realizing above technical purpose, the present invention by the following technical solutions:
