It is not fully up to expectations, it is concrete such as the application of household appliance appearance part in kitchen, people during high temperature cook food, household appliance appearance
Part unavoidably can be contacted with edible oil, and such as oil bloom splash, food is contacted, if cleared up not in time, the part of PP classes is with regard to pole
Permanent oil mark, oil stain are easily left, product appearance, and confidence of the consumer to appliance brand is had a strong impact on.
Trace it to its cause, this permanent oil mark, oil stain are carried out mainly due to edible oil to household appliance appearance PP parts surfaces
It is swelling to cause.Edible oil is close with PP material polarity, more difficult cleaning under normal temperature state, and is under electric working condition, its
The temperature on surface reaches as high as 80～100 DEG C, easily causes edible oil to the swelling of PP surfaces.With resistance to edible oil high temperature swelling
PP materials become industry focal point.
The content of the invention
It is an object of the invention to provide a kind of household electrical appliances modified polypropylene material of resistance to edible oil high temperature swelling.
It is a further object of the present invention to provide the preparation method of the polypropylene material.
To reach above-mentioned purpose, the present invention is employed the following technical solutions：
