Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of high density polyethylene(HDPE) toughening modifying master batch and preparation method thereof.
Background technology
High density polyethylene(HDPE) (HDPE) is a kind of range of application thermoplastics very widely, and world wide production is only second to PVC and LDPE occupies the 3rd.Because HDPE resin has good physical and mechanical properties, higher use temperature, good cold tolerance etc., are therefore widely used in processing various plastics.But because its degree of crystallinity is high, thereby defect restricted its scope of application such as its shock strength is poor and ESCR is poor, inside and outside native land, carry out a large amount of toughening modifying HDPE research work, the methods such as that people adopt is filling-modified, blending and modifying and direct tool are carried out study on the modification, wherein with filling-modified the most simple and economical.But traditional filling-modified often making significantly declines as toughness, the intensity of structured material Main Mechanical, and effect is not very desirable.
Summary of the invention
The object of the present invention is to provide and a kind ofly on low intensive basis, increase substantially rigidity and the large high density polyethylene(HDPE) toughening modifying master batch of toughness and preparation method thereof not falling.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high density polyethylene(HDPE) toughening modifying master batch, its component by mass percent proportioning is: carrier 10%～30%, talcum powder 50%～70%, expanding material 10%～25%, coupling agent 1%～3%, dispersion agent 0.5%～2%, oxidation inhibitor 0.1%～1%.
