Technical field
The invention belongs to BMC material technical field, in particular to a kind of high speed rotor plastic packaging BMC material and its preparation side
Method.
Background technique
Rotor is the rotary body by bearing support.Rotor is mostly the main rotation member in dynamic power machine and work mechanism.
Typical rotor has Turbomachine Rotor, rotor, the rotor of various pumps and rotor of turbocompressor etc..Rotor is certain
Very big deformation can occur and cause to resonate when being rotated under specific revolving speed, since rotor makees high speed rotary motion, so needing
Balance.
Existing ordinary motor rotor speed only has 5000r/min or so, and the material used is conventional motor plastic package material,
There are two types of types substantially for the high molecular structure of plastics: the first is linear structure, and the high-molecular compound with this structure claims
For chain macromolecule compound;Second is three-dimensional-structure, and the producing high-molecular with this structure is collectively referred to as three-dimensional polymeric molecule
Close object.Some macromolecules have branch, referred to as branched high molecular, belong to linear structure.Some macromolecules are although intermolecular friendship
Join, but crosslinking is less, referred to as reticular structure, belongs to three-dimensional-structure.Two different structures show two kinds of opposite performances.
Linear structure (including branched structure) high polymer is due to the presence of independent molecule, therefore flexible, plasticity, in a solvent can be molten
Solution, heating can melt, hardness and the lesser feature of brittleness.Three-dimensional-structure high polymer since no independent macromolecular exists, therefore
Without elasticity and plasticity, it cannot dissolve and melt, can only be swollen, hardness and brittleness are larger.The high score of plastics then two kinds of structures
Son has, and is thermoplastic made of linear macromolecule, is thermosetting plastics made of three-dimensional polymeric molecule.
The most of plastics of motor plastic package material are light, chemical stabilization, will not corrode;But it has the disadvantage that plastics are resistance to
Hot difference, coefficient of thermal expansion is big, easy firing;Poor dimensional stability is easily deformed;Weatherability is poor.In addition, being directed to part rotor
Revolving speed needs to reach the high revolving speed rotor of 20000r/min, using ordinary motor plastic packaging material, can because intensity not enough due to burst apart and fall off,
Seriously affect the service life of rotor and using safe.

At least one of the calcium carbonate of the aluminium hydroxide and partial size D50=5-8um of 8-10um, the aluminium hydroxide and calcium carbonate of above-mentioned partial size
With preferable oil absorbency, the combination of the two can effectively reduce the problems such as material, sand hole are lacked in material forming process, so that
Material has more preferable compactness.
It further include thickener to be conducive to material molding, the thickener is the magnesia of Chun Du≤99%.It adds pure
The magnesia of Du≤99% can be effectively improved the processing forming of high speed rotor plastic packaging BMC material as thickener.
Preferably, the unsaturated polyester resin is isophthalic neopentyl glycol resins, and the resin viscosity is in 2000-
3000mPa.S, solid content is in 60-65%, relative to other unsaturated polyester resins, has more excellent water resistance, weather-proof
Property and glass wellability;The low shrink resin is modified PS solution, with impact, excellent color compatibility and
Heat-resisting weatherability.
More effectively to slow down solidification of the BMC material inside the runner and mold in flow process, it is preferred that the suppression
Preparation is the hydroquinone or benzoquinones of Chun Du≤98%.
