The existing various exemplary embodiment that the present invention will be described in detail, the detailed description are not considered as the limit to the present invention System, and it is understood as the more detailed description to certain aspects of the invention, characteristic and embodiment.
It should be understood that heretofore described term is only to describe special embodiment, being not intended to limit this hair It is bright.In addition, for the numberical range in the present invention, it is thus understood that specifically disclose the range upper and lower bound and they it Between each median.Median and any other statement value in any statement value or stated ranges or in the range Each smaller range between interior median is also included in the present invention.These small range of upper and lower bounds can be independent Ground is included or excluded in the range of.
Unless otherwise stated, all technical and scientific terms used herein has the routine in field of the present invention The normally understood identical meanings of technical staff.Although the present invention only describes preferred method and material, the present invention's Implement or can also be used and similar or equivalent any method described herein and material in testing.The institute mentioned in this specification There is document to be incorporated by reference into, to disclosure and description and the relevant method of the document and/or material.It is incorporated to any When document conflicts, it is subject to the content of this specification.
In the case of without departing substantially from the scope or spirit of the invention, the specific embodiment of description of the invention can be done more Kind is improved and variation, this will be apparent to those skilled in the art.Other realities obtained by the specification of the present invention It is apparent obtain for technical personnel to apply mode.Present specification and embodiment are only exemplary.
It is open term, i.e., about "comprising" used herein, " comprising ", " having ", " containing " etc. Mean including but not limited to.
Heretofore described " part " unless otherwise instructed, by mass.
The preparation method of heretofore described rubber micropore backing plate, in preparation method using a sulfur foam into Type, vulcanization the specific steps are, the sheet rubber of extrusion forming is placed in closed mold, under a constant, utilize The sheet rubber is heated to 130~180 DEG C by microwave, carries out sulfur foam.
Sheet rubber is placed in a mold, in the environment of constant pressure, the sheet rubber in mold is carried out using microwave Heating, film is by alternating electromagnetic field, and under the action of fast-changing electromagnetic field of high frequency, the polarity of polar material takes in film Change to the variation with electromagnetic field, cause intermolecular interior friction, the electromagnetism field energy of microwave is converted into the thermal energy in medium, glue Piece temperature increases rapidly, achievees the purpose that microwave heating.Using microwave heating, microwave energy can all penetrate sizing material, directly It carries out sizing material integrally to heat, sizing material heating is rapid, and homogeneous heating is energy-efficient.
Under a constant, sizing material is heated to 130~180 DEG C using microwave, the raw rubber in sizing material occurs with vulcanizing agent Chemical reaction makes the crosslinking of its linear macromolecule structure become 3 D stereo reticular structure.The constant pressure belongs to 5~15MPa Range.Sulfidation is specially：Under the constant pressure of 5~15MPa, in 1~2min times, using microwave by the glue in mold Material is heated to 130~180 DEG C from room temperature, and activating agent, accelerating agent, vulcanizing agent, foaming agent in sizing material etc. are rapidly reached reaction and live Warm-natured degree so that sizing material quickly enters the heat cure phase from vulcanization induction period.Under the constant pressure of 5~15MPa, in 5~10min Time, using microwave to the sizing material continuous heating in mold so that the temperature of sizing material is maintained at 130~180 DEG C so that sizing material is complete Into crosslinking, foaming process, microcellular structure is formed.
In said program, before the vulcanisation step, which further includes step of plasticating, the step tool of plasticating Body is：Rubber is put into open mill, roll spacing is adjusted to 0~2mm carries out thin logical, beats triangle bag 3~4 times, plasticates to suitable Mooney The virgin rubber of viscosity.
In said program, mixing step is further included between step and the vulcanisation step in described plasticate, is specially：One Section be kneaded, by the virgin rubber plasticated, filler, plasticizer, activating agent, anti-aging agent and foaming agent addition mixer mixing 5~ 10min, mixer temperature are less than 80 DEG C, obtain one section of rubber compound；Two-stage mixing, by one section of rubber compound, vulcanizing agent and accelerating agent Mixing, it is thin 3 times logical, obtain rubber compound.
In said program, the rubber compound after two-stage mixing squeezes out or calendering formation.
