Abstract
The invention relates to a metallocene geomembrane which is used for railway laying, a refuse landfill, a tunnel, a penstock, a reservoir, a dyke, a sewage tank, an ecological tank, a landscape lake, an aquiculture tank and the seepage resistance and the water resistance of railway and highway engineering and is prepared by ingredients through a coextrusion machine. The metallocene geomembrane is characterized by comprising the following components by the weight percent: 64 to 73 of metallocene linearity low-density polyethylene, 24 to 32 of high-density polyethylene and 0.1 to 3 of assistant, wherein the assistant comprises a modifying assistant and a processing assistant, the modifying assistant is the antioxidant, and the processing assistant is carbon black or PPA. The Metallocene geomembrane has good puncture resistance, good,anti-tear property and high tensile strength.
Description
Technical field
The present invention relates to a kind of metallocene geomembrane, be used for railway laying, refuse landfill, tunnel, water channel, reservoir, dykes and dams, sewage lagoon, ecological pool, view lake, aquaculture pond and railway, the antiseepage of highway engineering, waterproof.
Background technology
In the antiseepage of railway laying, refuse landfill, tunnel, water channel, reservoir, dykes and dams, sewage lagoon, ecological pool, view lake, aquaculture pond and railway, highway, waterproofing work; The existing geomembrane that uses is high-density polyethylene geomembrane; Bring very big convenience to engineering; But in application, find to exist the problem a little less than geomembrane puncture resistance, the tear resistance, its physical strength awaits further improvement.
Summary of the invention
The object of the present invention is to provide a kind of metallocene geomembrane, puncture resistance is good, and tear resistance is good, and tensile strength is high.
Metallocene geomembrane of the present invention is processed through co-extrusion machine by batching, and its ingredients by weight percentage composition is:
Metallocene linear-low density polyethylene 64～73%, high density polyethylene(HDPE) 24～32% and auxiliary agent 0.1～3%.
Wherein:
High density polyethylene(HDPE) is called for short HDPE, and metallocene linear-low density polyethylene is called for short mLLDPE.
Auxiliary agent comprises modified additive and processing aid, and total amount is 0.1～3%, wherein:
Modified additive is an oxidation inhibitor, preferred having of using: hindered phenol antioxygen, and as 1010,1076, B215 etc. and hindered phenol antioxygen.
Processing aid is carbon black or PPA (fluoropolymer elastomerics).
The present invention is through adjustment prescription batching, and main ingredient wherein is adjusted into mLLDPE by HDPE, thereby has obtained metallocene geomembrane of the present invention, and its puncture resistance and tear resistance are good, and tensile strength is high, and concrete characteristics are following:
(1) transparency is good, and mist degree is lower; Glossiness is higher;
(2) tensile strength, tear strength are higher, and homogeneous relatively;
(3) shock strength is higher, and toughness is better;
(4) puncture intensity is higher;
(5) film viscosity is low;
(6) anti-chemical extraction resistance to crocking good;
(7) hot blast is functional, the lower and a wider range of hot blast temperature, good airproof performance.
Following with existing HDPE geomembrane performance:
The existing HDPE geomembrane of index project mLLDPE geomembrane of the present invention
Tensile strength (Mpa): 40.9 31.5
Elongation at break (%): 780 560
Angle tear strength (N/mm): 155 92.5
Puncture intensity (N): 540 320
