Description
Technical field
The invention belongs to field of polymer composite material, and in particular to a kind of air-conditioning wind wheel PP Pipe Compound and its preparation.
Background technique
Wind wheel is one of core component of air-conditioning, mainly uses fiberglass reinforced SAN (styrene-acrylonitrile) material at present, but
At high cost, complex process, recycling are difficult.
Acrylic resin (PP), source is wide, density is small, easy processing, at low cost, and is easily recycled, and it is right to be more able to satisfy society
The requirement of environmental protection.In the prior art, also have using acrylic resin as raw material, but finally prepare finished product shrinking percentage it is big,
Impact strength is low.
Summary of the invention
It is special the technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of improved air-conditioning wind wheel
Materials.
The present invention also provides a kind of preparation method of air-conditioning wind wheel PP Pipe Compound simultaneously.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
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 as:
Wherein, the acrylic resin is highly crystalline homopolypropylene.
Further, the miberal powder is sheet miberal powder.
Preferably, the miberal powder is the mixture of one of talcum powder, mica powder or both.
Preferably, the mesh number of the talcum powder is 5000~10000 mesh.
Further, the compatilizer is silane coupling agent, PP grafted maleic anhydride, one in POE grafted maleic anhydride
Kind or several mixing.
Further, the whisker is the calcium sulfate crystal whiskers of silane coupler modified mistake.
Further, the antioxidant is one or more of Hinered phenols antioxidant and phosphite ester antioxidant
Mixing.
In the present invention, raw material described in whole can not have by commercially available and/or take known means and be prepared
When being illustrated, it is all satisfied the requirement of standard chemical products.
The another technical solution 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 that acrylic resin, compatilizer, miberal powder, whisker and antioxidant are put into bolt screw extruder after mixing by formula
Main spout, alkali-free glass fibre puts into side spout, using shearing process, extruding pelletization is carried out, so that in finished particle
Glass fibre length be 550 microns~650 microns.
The shearing process, which uses, enables to the glass fibre length in finished particle for 550 microns~650 microns
Weak shearing process.
A kind of application of above-mentioned PP Pipe Compound on air-conditioning wind wheel.
Due to the implementation of above-mentioned technical proposal, the invention has the following advantages over the prior art:
The present invention uses highly crystalline homopolymerization PP, and suitable glass, miberal powder, whisker, compatilizer is added, effectively improves material
Rigid, miberal powder compounding whisker uses in formula, limits the conformation of polypropylene molecular chain, reduces molding shrinkage and warpage tendency,
Improve the dimensional stability of material.
Preparation method of the invention uses specific shearing process, so that glass fibre length is retained in 550-650 microns, effectively
Improve the rigidity of material.
Specific embodiment
Although general PP is more able to satisfy requirement of the society to environmental protection, general PP there are molding shrinkages big, easy warpage, just
Property it is insufficient the problems such as, be rigidly the performance weakness of general PP material for air-conditioning wind wheel material, compared to SAN material differ it is larger,
It is one of the key technology for limiting PP and being applied to air-conditioning wind wheel；Jerk value will reach air-conditioning standard and want between the leaf of wind wheel in operation
It asks, material is needed to have good compact dimensions stability, and general PP dimension stability difference is another pass of the project
Key technology.The present invention uses highly crystalline homopolymerization PP, and suitable glass, miberal powder, whisker, compatilizer is added, using weak shearing process,
So that Length of Glass Fiber is retained in 550-650 microns, effectively improves the rigidity of material.The present invention also uses the cunning with 5000-10000 mesh
Mountain flour also acts as nucleating agent in addition to playing humidification, and compounding mica, whisker use, and limit the structure of polypropylene molecular chain
As reducing molding shrinkage and warpage tendency, improving the dimensional stability of material.
