The calcium of above-mentioned closed-cell foam aluminium alloy by adding 2 parts ~ 2.5 parts, can in the standing process when melting, make a wherein part calcium and aluminium and oxygen etc. together with form fine and close complex oxide film on the surface of closed-cell foam aluminium alloy melt, described oxide-film can stop the further oxidation of closed-cell foam aluminium alloy melt, in addition, the calcium of another part is then dissolved in closed-cell foam aluminium alloy melt, intermetallic compound is formed with other elements such as aluminium, calcium after melting is dispersed in closed-cell foam aluminium alloy melt in whipping process, thus the viscosity stablization in closed-cell foam aluminium alloy melt is increased, thus make viscosity be more prone to control.
And for example, the above-mentioned closed-cell foam aluminium alloy of an embodiment comprises each component of following mass parts:
Titanium 0.5 part ~ 1 part;
Chromium 0.5 part ~ 1.5 parts;
Copper 0.8 part ~ 1.6 parts;
Vanadium 0.05 part ~ 0.1 part;
0.05 part ~ 0.1 part, manganese;
0.6 part ~ 0.9 part, zinc;
40 parts ~ 65 parts, aluminium;
Calcium 2 parts ~ 2.5 parts;
1 part ~ 1.5 parts, carborundum;
Titantium hydride 0.02 part ~ 0.03 part;
Alpha-alumina particles with nanometers size 0.05 part ~ 0.25 part;
Nanosized silica particles 0.05 part ~ 0.15 part.
Above-mentioned closed-cell foam aluminium alloy is by the titantium hydride of the carborundum and 0.02 part ~ 0.03 part that add 1 part ~ 1.5 parts, the effect of collaborative thickening can be played, make under the degree that above-mentioned closed-cell foam aluminium alloy pore structure is identical, can play and strengthen its yield strength with impact resistance, thus make the mechanical performance of described Novel LED lamp better.
Refer to Fig. 4, the preparation method of the above-mentioned closed-cell foam aluminium alloy of an embodiment comprises the steps:
S110: by the aluminium of 40 parts ~ 65 parts under the condition of 720 DEG C ~ 750 DEG C, is heated to fusing.
S120: continue heating, and in the aluminium after melting, add the zinc of the titanium of 0.5 part ~ 1 part, the chromium of 0.5 part ~ 1.5 parts, the copper of 0.8 part ~ 1.6 parts, the vanadium of 0.05 part ~ 0.1 part, the manganese of 0.05 part ~ 0.1 part and 0.6 part ~ 0.9 part, and stir under the stir speed (S.S.) of 1200rpm ~ 1500rpm, wherein, mixing time is 200 seconds ~ 250 seconds.
S130: continue heating, add the calcium of 2 parts ~ 2.5 parts, and stir under the stir speed (S.S.) of 1200rpm ~ 1500rpm, wherein, mixing time is 200 seconds ~ 250 seconds.
S140: continue heating, add the alpha-alumina particles with nanometers size of 0.05 part ~ 0.25 part and the nanosized silica particles of 0.05 part ~ 0.15 part, and after stirring under the stir speed (S.S.) of 1200rpm ~ 1500rpm, obtain aluminium alloy melt, wherein, mixing time is 200 seconds ~ 250 seconds.
S150: continue heating, add 0.02 part ~ 0.03 part add titantium hydride, and stir under the stir speed (S.S.) of 1200rpm ~ 1500rpm, wherein, mixing time is 200 seconds ~ 250 seconds, and then, insulation leaves standstill, and foams.
S160: the described aluminium alloy melt after foaming adopts each to cooling simultaneously, obtains described closed-cell foam aluminium alloy.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
