Description
Technical field
The invention belongs to the technical fields of PP composite material, particularly relate to a kind of air conditioner outdoor machine high intensity Gao Chong
Hit weather resisting polypropylene material and preparation method thereof.
Background technique
Material used in the shell of air-conditioner outdoor unit is generally metal material on the market, and most of metal material is cold-reduced sheet
The sheathing material of spray mo(u)lding, and the corrosion resistance of cold-reduced sheet is poor, and China every year constantly increases the consumption of steel,
So the cost of steel can be higher and higher.Plastic material is a kind of material of good performance, in recent years, China's air-conditioner outdoor unit
Shell gradually adopts polypropylene plastics to replace traditional cold-reduced sheet for applying anticorrosive paint outside.
Polypropylene is the highly crystalline polymer of nontoxic, odorless, tasteless milky, and density only has 0.90-0.91g/cm3,
It is one of kind most light in current all plastics, and processing performance is good, heat resistance with higher and electrical insulation capability, quilt
It is widely used in household electrical appliance, automobile industry, machine components and electronic device.It is long since air-conditioner outdoor unit is all mounted on outdoor
Year be subjected to burning sun be exposed to the sun, rain drop erosion and frost severe cold, it is well known that plastic products the alternating of high temperature and severe cold strike under very
The aging phenomena such as cracking, modification, colour fading are easy to produce, this just directly affects the service life of entire unit.
The performance requirement of air-conditioner outdoor unit material is all not achieved in the mechanical property and weather resistance of polypropylene bulk material, needs
Further addition filler and auxiliary agent etc. is modified, and PP composite material is made, to improve the intensity of polypropylene bulk material, resist
Impact and weather resistance.Due to auxiliary agent addition can intensity to PP composite material and shock resistance cause very big shadow
It rings, existing PP composite material is unreasonable since auxiliary agent adds, and mechanical properties decrease is tight while weatherability improves
Weight；And conflict effect occurs while improving its mechanical property with auxiliary agent for the addition of filler, is unable to satisfy its weatherability
The requirement of air-conditioner outdoor unit；Therefore, existing PP composite material is limited by very large in the application of air-conditioner outdoor unit.
Summary of the invention
The present invention provides a kind of air conditioner outdoor machine high intensity HI high impact weather resisting polypropylene material and preparation method thereof, solves
The intensity of PP composite material, shock resistance and weather resistance, which cannot be taken into account, in the prior art is unable to satisfy air-conditioner outdoor unit
The problem of housing requirements.
A kind of air conditioner outdoor machine high intensity HI high impact weather resisting polypropylene material of the invention mainly passes through following skill
Art scheme is realized: the raw material including following parts by weight: 55-77 parts of copolymer polypropylene, 8-40 parts of homopolypropylene, and POE
