The requirement of environmental protection.In prior art, also have using acrylic resin as raw material, but finally prepare finished product shrinkage factor it is big,
Impact strength is low.
The content of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, there is provided a kind of improved air-conditioning wind wheel is special
Materials.
The present invention also provides a kind of preparation method of air-conditioning wind wheel PP Pipe Compound simultaneously.
To solve above technical problem, the present invention is adopted the following technical scheme that：
A kind of air-conditioning wind wheel PP Pipe Compound, weight percentage, the formula material of the air-conditioning wind wheel PP Pipe Compound by with
The following group is grouped into：
Wherein, the acrylic resin is highly crystalline HOPP.
Further, the breeze is lamellar breeze.
Preferably, the breeze be Pulvis Talci, the mixture of one or both in mica powder.
Preferably, the talcous mesh number is 5000～10000 mesh.
Further, the compatilizer be silane coupler, PP grafted maleic anhydrides, in POE grafted maleic anhydrides one
Plant or several mixing.
Further, the whisker is the calcium sulfate crystal whiskers of silane coupler modified mistake.
Further, the antioxidant is one or more in Hinered phenols antioxidant and phosphite ester kind antioxidant
Mixing.
In the present invention, all described in raw material can not have by commercially available and/or take known means preparing
When being illustrated, the requirement of standard chemical products is satisfied by.
The another technical scheme that the present invention takes is：A kind of preparation method of above-mentioned air-conditioning wind wheel PP Pipe Compound, the preparation
Method is, by formula, will to put into bolt screw extruder after acrylic resin, compatilizer, breeze, whisker and antioxidant mix homogeneously
Main spout, alkali-free glass fibre input side spout, using shears technique, carry out extruding pelletization so that in finished particle
Glass fibre length be 550 microns～650 microns.
The shears technique adopts the glass fibre length enabled in finished particle for 550 microns～650 microns
Weak shears technique.
A kind of application of above-mentioned PP Pipe Compound on air-conditioning wind wheel.
Due to the enforcement of above-mentioned technical proposal, the present invention is had the advantage that compared with prior art：
The present invention adopts highly crystalline homopolymerization PP, adds suitable glass, breeze, whisker, compatilizer, effectively improves material
Rigidity, in formula, breeze compounding whisker is used, and limits the conformation of polypropylene molecular chain, reduces molding shrinkage and warpage tendency,
Improve the dimensional stability of material.
The preparation method of the present invention adopts specific shears technique, makes glass fibre length be retained in 550-650 microns, effectively
Improve the rigidity of material.
Specific embodiment
Although general PP can more meet requirement of the society to environmental protection, there is big molding shrinkage, easy warpage, just in general PP
Property it is not enough the problems such as, for air-conditioning wind wheel material, be rigidly the performance weakness of general PP materials, it is larger to compare SAN material difference,
It is to limit PP to be applied to one of key technology of air-conditioning wind wheel；Between wind wheel leaf in operation, jerk value will reach air-conditioning standard and want
Ask, need material to have good compact dimensions stability, and general PP dimension stabilities difference is another pass of the project
Key technology.The present invention adopts highly crystalline homopolymerization PP, adds suitable glass, breeze, whisker, compatilizer, using weak shears technique,
Make Length of Glass Fiber be retained in 550-650 microns, effectively improve the rigidity of material.The present invention is also using the cunning with 5000-10000 mesh
Stone powder, also acts as nucleator except playing potentiation, and compounding Muscovitum, whisker are used, and limit the structure of polypropylene molecular chain
As reducing molding shrinkage and warpage tendency, improving the dimensional stability of material.
With reference to specific embodiment, the invention will be further described.
