Description

A kind of bi-material layers height rebound diaphragm
Technical field
The present invention relates to a kind of filter press diaphragm technical fields, and in particular to a kind of bi-material layers height rebound diaphragm.
Background technique
The material of diaphragm is that polypropylene adds elastic body toughening to be made at present, the disadvantage is that material properties are still the category of plastics Property, rigidity is big under room temperature, be not easy deformation, cannot restore after deformation occurs, and the use process of diaphragm be for a long time stretch it is multiple Position it is reciprocal during, material just generates stress relaxation after a period of time, and deformation can not reset, and scraps product；Therefore, it is necessary to A kind of bi-material layers height rebound diaphragm.
Summary of the invention
The purpose of the invention is to overcome the deficiencies in the prior art, and provide a kind of high resiliency, with long service life one Kind bi-material layers height springs back diaphragm.
The object of the present invention is achieved like this: a kind of bi-material layers height rebound diaphragm weighs SEBS28- in parts by weight 40%, white oil 20-40%, polypropylene 20-30%, high density polyethylene (HDPE) 8-15%, nanometer calcium carbonate 3-6% and antioxidant 0.2-0.5%.
A kind of bi-material layers height rebound diaphragm, weighs SEBS33%, polypropylene 22%, high density polyethylene (HDPE) in parts by weight 9%, it is all uniformly mixed, and puts into double screw extruder by nanometer calcium carbonate 5% and antioxidant 0.3%, is subsequently injected into white oil 30%, extruding pelletization is carried out to obtain high resilient film piece core material.
The SEBS is The linear tri-block copolymer of intermediate elastic block.
The white oil is industrial grade white oil.
The polypropylene uses the polymerization of copolymerization or homopolymerization.
The antioxidant is irgasfos 168 or antioxidant 1010.
The nanometer calcium carbonate can be replaced with talcum powder more than 3000 mesh.
The beneficial effects of the present invention are: SEBS is free of unsaturated double-bond, therefore with good stability and resistance to ag(e)ing； Polypropylene is a kind of hemicrystalline thermoplastic；Impact resistance with higher, engineering properties is tough, resists a variety of organic solvents And acid and alkali corrosion；High density polyethylene (HDPE) is that a kind of crystallinity is high, non-polar plane is in a degree of translucent；Its crystallinity 80% ~ 90%, softening point is 125 ~ 135 DEG C, using temperature up to 100 DEG C；120 ~ 160 DEG C of fusion temperature, it has good resistance to Hot and cold resistance, chemical stability is good, rigidity and toughness also with higher, and mechanical strength is good；Dielectric properties, resistance to environment are answered Power cracking behavior is also preferable；Irgasfos 168 is a kind of phosphite antioxidant haveing excellent performance, and anti-extractibility is strong, is made to hydrolysis With stabilization, and the photostability of product can be significantly improved, can be used in combination with a variety of phenolic antioxidants；It weighs in parts by weight A kind of bi-material layers height rebound diaphragm, weighs SEBS33%, polypropylene 22%, high density polyethylene (HDPE) 9%, nano-sized carbon in parts by weight It is all uniformly mixed, and puts into double screw extruder by sour calcium 5% and antioxidant 0.3%, is subsequently injected into white oil 30%, is squeezed Be granulated out to obtaining high resilient film piece core material, prepared by the above method with high resiliency, and resilience performance it is excellent, The material property for not generating stress relaxation under conditions of reciprocal use, improving diaphragm is resetted in long-term stretching, extends film The service life of piece；To sum up, the present invention has the advantages that high resiliency, long service life.
