Description
Technical field
The invention discloses a kind of preparation methods of yielding rubber, belong to technical field of polymer materials.
Background technique
Damping mechanical equipment, railroad track, ship, bridge, in terms of have important use.Especially in recent years
Come, earthquake frequently occurs, directly or indirectly to society and damage naturally so that damping is particularly important.In damping
In material, rubber is played an increasingly important role, and is the direction of vibration-absorptive material development.The characteristics of rubber is existing high-elastic
Property, and have high viscosity, and there are also its distinctive comprehensive mechanical property, i.e., low adjustable modulus and higher intrinsic resistances
Buddhist nun keeps its effect in terms of buffering, damping and dynamic sealing unrivaled.The shock absorption principle of rubber product utilizes rubber
High viscosity absorbs vibrational energy, and the mechanical energy of absorption or sound can be partially converted into thermal energy and dissipated, and subtracts to play
Less or reduce amplitude effect.
The morphosis because being known as rubber material, the blend rubber system each component of rubber damping damping performance are influenced at present
Compatibility, cross-linking system, use temperature and vibration frequency, polymer blending ratio, reinforcing filler and other auxiliary agents etc..
Natural rubber (NR) is the product of biosynthesis, and main component is rubber hydrocarbon, also containing a small amount of protein, fatty acid etc..Its
Processing method is a variety of, and the component content of obtained various NR is different, and mechanical property, damping performance etc. are also variant, in relation to this
The research of aspect is very few.
It is set as the heavy constructions such as damper element, especially senior constructure, bridge, internal combustion engine, train head or machinery
Standby foundation shock absorption element, relatively difficult due to installing and replacing, costly, product, which generally requires to have, longer uses the longevity
Life, to reduce maintenance and renewal cost.In the various factors for influencing shock absorbing rubber product service life, thermo-oxidative ageing is most heavy
One of factor wanted.This is because rubber itself is the non-conductor of heat, the mechanical energy that damping is absorbed is after being converted into thermal energy
It cannot be dissipated in time, therefore rubber will heat up, and the raising of temperature is in addition to declining the performance of rubber product, it is more main
What is wanted is the thermo-oxidative ageing process that will greatly accelerate rubber product, so as to shorten its service life.Therefore, as can inhibiting rubber
Thermo-oxidative ageing process, can improve the heat aging property of rubber product, to extend the service life of product.
Summary of the invention
The present invention solves the technical problem of: in use for conventional base rubber material, damping is inhaled
The mechanical energy of receipts cannot be dissipated in time after being converted into thermal energy, accelerate the thermo-oxidative ageing of rubber, lead to product service life
Shorter problem provides a kind of preparation method of yielding rubber.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
(1) glass fibre is mixed for 1:50~1:80 in mass ratio with dopamine solution and impregnates 45~60min, using
Filter, obtains pretreated glass fiber；
It (2) is in mass ratio that 1:30~1:40 mixes addition reactor with ferric chloride solution by pretreated glass fiber, point
After dissipating uniformly, then 2~3 times of ferric chloride solution volume of urea liquid is added dropwise into reactor, wait be added dropwise, the reaction was continued 3
~5h, then it is aged, be filtered, washed and dried to obtain modified glass-fiber；
(3) according to parts by weight, 100~120 parts of hydrogenated nitrile-butadiene rubbers, 10~15 parts of poly-methyl methacrylates are successively taken
Ester, 8~10 parts of Corvics, 8~10 parts of Petropols, 10~20 parts of modified glass-fibers, 3~5 parts of sulphur, 1~3 part
Hydrogenated nitrile-butadiene rubber is first plasticated after 10~15min, is sequentially added poly- by promotor, 2~4 parts of anti-aging agents, 1~4 part of plasticizer
Methyl methacrylate, Corvic, Petropols, modified glass-fiber, sulphur, promotor, anti-aging agent and plasticizer,
After being kneaded 10~20min, and apply external magnetic field in mixing process, end to be mixed stands 6~8h, obtains rubber compound；
(4) mixing glue is heated into 45~60min of vulcanization, discharged to get yielding rubber.
Step (1) glass fibre is any one in alkali-free glass fibre or medium-alkali glass fibre.
Step (3) Petropols are any one in C5 Petropols or C9 Petropols.
Step (3) promotor is any one in Vulcanization accelerator TMTD, captax or promotor ZDMC.
Step (3) described anti-aging agent is mixed in mass ratio for 1:1:1 by antioxidant 4020, anti-aging agent RD and antioxidant NBC
It closes.
Step (3) the plasticizer is in dibutyl phthalate, octyl epoxy stearate or dioctyl adipate
Any one.
The beneficial effects of the present invention are: (1) technical solution of the present invention carries out glass fibre first with dopamine solution
It impregnates and is modified, improve the absorption property of glass fibre, then modified glass fibre is mixed with ferric chloride solution, be with urea
Precipitating reagent, make hydrolysis of urea generate hydroxide ion with iron ion in conjunction with, generation iron hydroxide nucleus, nucleus once being formed,
It is adsorbed by the dopamine of fiberglass surfacing, in subsequent processes, iron hydroxide dehydration generates iron oxide, and aoxidizes
Iron uniform adsorption improves the roughness of fiberglass surfacing in fiberglass surfacing, is conducive in subsequent processes linear
Rubber molecule, which is affiliated to, is wound in coarse fiberglass surfacing, in by vibration deformation process, can effectively improve rubber molecular chain
The resistance of motion steeply rises system internal friction, converts the mechanical energy that vibration generates to thermal energy and dissipate, at the same by
During power, glass fibre can share jointly external force with rubber molecular chain, disperse stress, play reinforcing effect, avoid system
Stress is concentrated and causes structure and elastic change dramatically, effectively limits the large scale deformation of product under external force, makes product
Mechanical property is further promoted, in addition, after iron oxide is adsorbed on fiberglass surfacing, it can be in process with externally-applied magnetic field side
To the enhancing network structure for making glass fibre form oriented alignment in rubber matrix, to effectively improve the thermal conductivity of system
Can, the thermal energy fast dissipation that conversion is formed avoids thermal energy buildup from causing rubber thermo-oxidative ageing inside system；(2) of the invention
Technical solution can increase rubber by adding polymethyl methacrylate, Corvic and Petropols in rubbery system
The polarity of xanthan molecule improves cohesive strength and surface energy, in addition, the addition of Petropols, can effectively improve system to glass fibers
The wettability of dimension effectively improves product mechanical performance to improve the binding force between system and glass fibre；
(3) technical solution of the present invention, can after nitrile rubber hydrogenation treatment using hydrogenated nitrile-butadiene rubber as base rubber material
The unstable double bond in rubber molecule is effectively reduced, so that effectively reduce rubber molecule occurs deterioration by oxidation under heating condition
Problem.
