Abstract
Polypropylene (PP) is a non-polar crystalline plastic, is one of five classes of general plastics, has characteristics of rich raw material source, cheap price, easy processing molding and the like so as to provide wide uses, and further has disadvantages of poor cold resistance, easy breaking at a lower temperature, high shrinkage rate, poor creep resistance, poor product size stability, and easy denaturation. The hollow glass micro-beads contain air, and have characteristics of low thermal conductivity, light weight, smooth surface and the like. According to the present invention, the good thermal insulation performance polymer can be prepared; a purpose of the present invention is to provide a special polypropylene modified material with characteristics of no influence on mechanical property and environmental protection; and the raw materials of the hollow glass micro-bead reinforced polypropylene material comprise, by weight, 70-80 parts of polypropylene, 1.0-3.0 parts of a silane coupling agent, 1.0-3.0 parts of an antioxidant, 10-30 parts of hollow glass micro-beads, 0.5-1.5 parts of a dispersion lubricant, and 0.5-1.5 parts of a dispersant.
Description
Technical field
The invention belongs to polypropylene material production technical field, improve the original deficiency of polypropylene.Produce the product meeting social demand.
Background technology
Polypropylene (PP) is nonpolar crystalline plastics, is one of five large class general-purpose plastics, and raw material supplied materials is abundant, low price, be easy to machine-shaping etc., and therefore purposes widely.Although polypropylene has many merits, also come with some shortcomings part.Maximum shortcoming is that winter hardiness is poor.Low temperature is easily broken, and shrinking percentage is large, and creep resistance is poor, product size poor stability, volatility.Containing gas in hollow glass micropearl, the low light weight of thermal conductivity and smooth surface etc.The polymkeric substance that insulation mechanical property is good can be prepared.
Summary of the invention
The object of this invention is to provide a kind of mechanical property not affecting material, the polypropylene dedicated modified materials of environmental protection.Hollow glass micropearl Reinforced Polypropylene material, is made up of following weight ratio raw material:
