Abstract
The invention provides a polypropylene-modified sound insulation material, which consists of the following components in percentage by mass: 10 to 85 percent of polypropylene; 10 to 70 percent of barium sulfate; 4 to 20 percent of glass fibres; and 0.1 to 2 percent of coupling agent. By using the barium sulfate and the glass fibres for filling and modification, the good mechanical property is guaranteed and good sound insulation property is achieved.
Description
Technical field
The present invention relates to a kind of polypropylene modified material and preparation method thereof, especially a kind of polypropylene modified material and preparation method thereof with sound-proofing properties.
Background technology
Vestolen PP 7052 (PP) is as a kind of resins for universal use, and it has good mechanical property and processing characteristics, thermotolerance, and is cheap, in plastics, occupies an important position, and is widely used in the daily life.But Vestolen PP 7052 is used on the parts of some household electrical appliance, and its sound insulation property far can not meet the demands.Sound-proof material adopts polyurethane foam plastic more, but because price is higher, and intensity is less, has also limited its use range.Though the PP source is abundant, low price, also there is the product size poor stability in stable performance, is prone to buckling deformation takes place, and for overcoming these shortcomings, generally adopts filler modified Vestolen PP 7052 at present, to satisfy the request for utilization of goods.
In polypropylene blending modified system, add the raw materials cost that filler can reduce goods, improve the intensity and the rigidity of modified polypropene goods.General choice spun glass and lime carbonate is as filler in the prior art, but during with their filling-modified PP, the shrinking percentage of material is bigger, and sound insulation property is poor.
Summary of the invention
The present invention seeks to deficiency, a kind of polypropylene modified material with sound-proofing properties and preparation method thereof is provided to the prior art existence.
For realizing above-mentioned purpose, polypropylene modified material of the present invention can adopt following scheme:
A kind of sound-proof material of polypropylene modification, the sound-proof material of this polypropylene modification is made up of following component by mass percent:
Vestolen PP 7052 10%-85%; Permanent white 10%-70%; Spun glass 4%-20%; Coupling agent 0.1%-2%.
To the problem that exists in the prior art, the present invention is through using permanent white and spun glass filling-modified in material, to guarantee excellent mechanical property and to increase good sound insulation property.
For realizing above-mentioned purpose, the preparation method of polypropylene modified material of the present invention can adopt following scheme:
A kind of preparation method of sound-proof material of polypropylene modification, this preparation method may further comprise the steps:
(1) handle spun glass with silane coupling agent, handle permanent white with aluminate coupling agent, for use;
(2) high-speed mixer is provided, and according to proportioning as claimed in claim 1 each constituent materials is put into high-speed mixer and form mixture;
(3) twin screw extruder is provided, it is mixing that the mixture in the step (2) is put into twin screw extruder;
(4) extrusion moulding tie rod from twin screw extruder, tie rod is crossed the water cooling pelletizing.
To the problem that exists in the prior art, preparation method of the present invention is through using permanent white and spun glass filling-modified in material, to guarantee excellent mechanical property and to increase good sound insulation property.
