Description
Technical field
The present invention relates to polymer modification technical field, be specifically related to a kind of low gloss, imitative flocking effect polypropene composition and its preparation method and application.
Background technology
Polypropylene, because the features such as its high comprehensive performance, wide material sources, light weight are inexpensive, easy-formation processing become one of most important general-purpose plastics, is also to apply in recent years the fastest plastics variety.Exploitation and the application of MODIFIED PP material on automobile is also the focus that automotive industry and plastics industry are paid close attention to always.But when modified polypropene is applied to automotive upholstery as plastic component, its plastic properties is denounced by human consumer always, how to reduce plastic sense and the smell of polypropylene composite material and in recent years paid attention to by automobile main frame maker gradually.
The glossiness that reduces polypropylene material is regarded as reducing a kind of method of plastic sense, the preparation method of a kind of low gloss hard plastic dashboard by polypropylene composite material that application number has been 201310713659.7 patent Introduction, it adopts the short method of cutting flat glass fiber of interpolation not only to obtain the material that surface hardness is higher, and play matt effect, reduce the glossiness of material, reached the object that reduces material plastic sense.Various effort are all done at reduction automotive trim plastic sense by each main engine plants at present, and the present invention has developed a kind of material that can effectively reduce interior trim component plastic sense from another one angle.
Summary of the invention
Primary and foremost purpose of the present invention is to provide a kind of low gloss, imitative flocking effect polypropene composition, and said composition, by adding man-made fiber point, can effectively reduce the plastic sense of material.
Another object of the present invention is to provide the preparation method of above-mentioned low gloss, imitative flocking effect polypropene composition.
The present invention is achieved through the following technical solutions:
A kind of low gloss, imitative flocking effect polypropene composition, by weight percentage, comprise following component:
Acrylic resin 43-99.8%
Mineral powder 0-30%
Toughner 0-20%
