Preferably, the TPEE raw material is made of hard polyester segments and soft chain segment, and hard segment pushes up binary by para Toluic Acid Composition, soft chain segment are obtained by ethylene oxide-capped poly- (propylene oxide) glycol derivative.
Preferably, in the high molecular material, the mass ratio of nucleating agent is the mass ratio of 0.01% to 2%, antioxidant Mass ratio for 0.01% to 2%, stabilizer is 0.05% to 4%, the mass ratio of defrother is 0.01% to 1%, thermostabilization The mass ratio of agent is 0.01% to 1.5%.
Preferably, after the high molecular material is by raw material stoving, passes through extruder modification and auxiliary agent extrusion is added, squeeze Materials in the tube after out carry out second-compressed molding, annealing again.
Preferably, the described ontology tool is there are four part, the cross sectional dimensions of first part and Part III have by The outer cross-sectional dimension gradually increased；The cross sectional dimensions of its second part and Part IV is gradually reduced.
Preferably, the ontology has a closed end regions.
Preferably, the cross section of the elastomeric spring and reinforcer is in a ring that the cross sectional dimensions of reinforcer is less than The cross-sectional dimension of elastomeric spring.
Preferably, the first end of the ontology be equipped with installation seam allowance, the rigid element of the first end in a ring, Internal diameter is identical as the installation outer diameter of seam allowance, and rigid element is sheathed on the installation seam allowance of first end.
Preferably, the rigid element of the second end is in pie, is fixed on the second end.
Preferably, the rigid element extends in the radial direction of ontology.
Make product that there is splendid cushioning ability, elastic recovery capability, excellent fatigue using above-mentioned high molecular material Performance, product can be worked normally in 40 degrees below zero into 120 degree of environment above freezing, and high molecular material is pollution-free, replacement Easy to maintain, long service life；There are four part, the cross sectional dimensions of first part and Part III has product ontology tool The outer cross-sectional dimension being gradually increased；The structure that the cross sectional dimensions of its second part and Part IV is gradually reduced, allow its Compression bearing capacity gets a promotion, improves.
Detailed description of the invention
Fig. 1 is main view of the invention；
Fig. 2 is sectional side elevation of the invention.
In figure, first part -1, second part -2, Part III -3, Part IV -4, the second end -5, reinforcer -6, Rigid element -8, cavity -9, first end 10, ontology 11.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
A kind of macromolecular elastomer spring, including a macromolecular elastomer ontology 11, ontology 11 first end 10 with Extend between the second end 5, reinforcer 6 is arranged in the middle part of both ends, middle part is hollow structure, and cavity 9 is semiellipse cone；Ontology For 11 tools there are four part, the cross sectional dimensions of first part 1 and Part III 3 has the outer cross-sectional dimension being gradually increased； The cross sectional dimensions of its second part 2 and Part IV 4 is gradually reduced；It has a closed end regions；Ontology 11 First end 10 be equipped with installation seam allowance, the rigid element 8 of first end 10 in a ring, internal diameter and installation seam allowance outer diameter Size is identical, and rigid element 8 is sheathed on the installation seam allowance of first end 10；The rigid element of the second end 5 is in pie, is fixed In the second end 5；Rigid element 8 extends in the radial direction of ontology；
