Abstract
The invention provides a method for spraying a thermal control coating on the surface of a honeycomb structure on the inner side of a spacecraft sun shade. The method comprises the following steps: spraying on the surface of the honeycomb structure is performed through the procedures of surface pretreatment, cleaning, spraying, leakage detecting and supplementary spraying. Through the method for the spraying on the surface of the honeycomb structure, a delustering and thermal control coating which is tidy in outer appearance, even in thickness and excellent in adhesive force is formed on the surface of the honeycomb structure through spraying, the requirements of the spacecraft sun shade on the thermal control coating can be met, and the reliability of a spacecraft in-orbit operation is improved. The method provided by the invention is strong in practicability, simple and easy to lean, can prevent blindness in the spraying on the honeycomb structure, improves the working efficiency and coated product quality.
Description
Technical field
The present invention relates to the honeycomb surface spraying method in coating and application techniques field, specifically honeycomb heat control coating layer on surface spraying method inside a kind of spacecraft sky shade.
Background technology
Sky shade, is mounted in optical lens, camera and video camera front end, blocks the device of harmful light, is also one of the most frequently used optical accessory.Sky shade, for suppressing picture halation, avoiding veiling glare to enter camera lens, protecting camera and camera lens to exempt from accident collision, can play good effect for the potential quality etc. giving full play to lens optical.The inwall of high-quality sky shade is through multiple delustring process, and the reflectivity of its inwall is only about 10%, and during use, itself can not produce refraction to eyeglass.
Inside spacecraft sky shade, spray delustring thermal control coating is one of important measures of inner surface delustring process.But honeycomb surface spraying uneven thickness inside sky shade, the blocked up place of coating then there will be tendency of chapping, and cause adhesive force poor, the place of cover light or drain spray then can be carried out reflective, affects image quality.Therefore, the whether even application of delustring thermal control coating relation to the image quality of spacecraft, become the new bottleneck that spacecraft sky shade is effectively applied.
At present, the patent in coating spraying method is a lot, and the old positive person of outstanding talent of such as TaiWan, China illustrates a kind of groove type spreader surface spraying method; Wang Yuning toasts lower-cost spraying method for the shell of consumer electronic product as mobile phone or computer etc. provides a kind of; Ge Xianci is easy to for automobile metal plate spray industry provides a kind of technological process compared with standard and has a kind of vehicle spray painting method that vehicle spray painting personnel grasp spraying technology, but does not all relate to for honeycomb surface coating spraying implementation method.
Because current spacecraft optical imagery load increases, quality of optical imaging requires to improve, therefore inside spacecraft sky shade the coating of honeycomb need that flat appearance, thickness are even, adhesive force well, do not have drain spray phenomenon, for the imaging in-orbit of spacecraft provides effective guarantee, therefore, the research for honeycomb heat control coating layer on surface spraying method has great importance.
Summary of the invention
The present invention is directed to above shortcomings in prior art, provide honeycomb heat control coating layer on surface spraying method inside a kind of spacecraft sky shade, the appearance of coat obtained by the method is smooth, thickness is even, adhesive force well, do not have drain spray phenomenon, thus meet the demand of the honeycomb such as the sky shade of modern spacecraft surface to thermal control coating.
The present invention is achieved by the following technical solutions.
Honeycomb heat control coating layer on surface spraying method inside a kind of spacecraft sky shade, comprises the following steps:
Step 1, surface pretreatment: the honeycomb that righting is collapsed, and remove the remaining calymma of honeycomb;
Step 2, cleaning: adopt dust exhaust apparatus dust out and cull particle, and adopt lance ejection cleaning agent to clean honeycomb surface;
Step 3, spraying: adjustment torch parameters, adopts spray gun to spray coating;
Step 4, leak detection: adopt glare light electric torch to carry out drain spray inspection to honeycomb surface;
Step 5, fills spray: adopt spray gun to carry out a spray to drain spray place.
Preferably, in step 1, described remaining calymma is bottom honeycomb and honeycomb port diameter is greater than the calymma of 1mm.
Preferably, in step 2, described cleaning agent be following any one or appoint multiple:
-acetone;
-butyl acetate;
-absolute ethyl alcohol;
-dimethylbenzene.
Preferably, in step 3, described torch parameters comprises spray gun bore, spraying swath and spray gun pressure.
Preferably, described spray gun pressure is 0.1 ~ 0.3Mpa.
Preferably, in step 4, the luminous flux of described glare light electric torch is greater than 240 lumens.
Compared with prior art, the present invention has following beneficial effect: go out flat appearance at honeycomb surface spraying, thickness is even, delustring thermal control coating that adhesive force is good, meet the requirement of spacecraft sky shade to thermal control coating, improve spacecraft reliability in orbit.The present invention has very strong practicality, and simply, easy to learn, the blindness to honeycomb spraying can be avoided, increase work efficiency and the quality of sprayed product.
