Number explanation in figure：1 it is upper plate, 11 be upper limit bar, 12 be limiting slot, 13 be buffer part, 2 be lower plate, 21 is Lower limit bar, 22 be bolt hole, 3 be buffer layer, 31 be rubber hexagonal prisms, 32 be coating, 4 be location hole.
Embodiment
It is a kind of compartment damping rubber pad of structure of the present invention as shown in Figs. 1-2, between compartment and chassis, Four corners are normally placed at, for reducing the vibrations in compartment.Including upper plate 1 matched with compartment, with chassis it is matched under The buffer layer 3 of plate 2 and setting between the upper and lower plates；
Both ends are equipped with upper limit bar 11 on the upside of the upper plate, and upper limit bar is engaged with the crossbeam on carriage frame, prevents compartment Displacement is produced between damping rubber pad, limiting slot 12 is provided with positive stop strip stage casing, the fixation of longitudinal direction can be carried out at limiting slot, Typically it is spirally connected in crossbeam in the position of limiting slot a bolt, can be to avoid damping rubber pad with respect to crossbeam length direction vibration. Trapezoidal buffer part 13 is integrally formed with the downside of upper plate；Trapezoidal buffer part can compartment crank timing or provide when rocking can The support leaned on, when slight shift occurs such as center of gravity, upper plate is slightly slanted, for example, when tilting to the left, at this time, the rubber section in left side Point deflection is larger, right side it is relatively small, that is, a part of strength is offset by the elasticity of rubber, to prevent lower plate the bottom of from Come off on frame or between be subjected to displacement, lower plate is equipped with bolt hole 22 matched with chassis between two lower limit bars, can make Lower plate and chassis are spirally connected fixation, so as to increase its security.The location hole 4 of mutual cooperation is additionally provided with upper plate and lower plate, Used with being positioned during the vulcanization of rubber, so that the position of each several part is relatively accurate.
Both ends are equipped with lower limit bar 21 on the downside of lower plate；Upper limit bar and/or lower limit the bar section is right-angled trapezium, should The setting of shape can provide the spacing strength of maximum.The upper and lower plates are metal material, such as iron or steel, large carrying capacity, no Yielding, the buffer layer is rubber material, and buffer capacity is strong, good damping effect.
Preferably：If the buffer layer includes dry rubber substance hexagonal prisms 31, coating 32, institute are equipped with the outside of rubber hexagonal prisms State coating as a shell by rubber hexagonal prisms tightly be bundled together to form a honeycomb, honeycomb Rubber bodies have the bearing capacity of bigger than the rubber bodies of integrative-structure, there is provided more preferable elastic buffer.
Preferably：Skid resistant course is equipped with the outside of the upper plate and lower plate, the skid resistant course is rubber layer, is on the one hand added Adhesive force between compartment and chassis, while also make that this structure is wear-resisting, antiseptic property increase.
The invention also discloses a kind of preparation method of compartment damping rubber pad, i.e. the wherein preparation side of yielding rubber Method, other structures are not the inventive points of the present invention, can by existing manner carry out, no longer be described in detail in the application, including such as The each component of lower mass fraction：100 parts of natural rubbers, 4 parts of nano zine oxides, 1.5 parts of stearic acid, 0.5 part of anti-scorching agent CTP, 35 parts of high wear-resistant carbon blacks, 3.4 parts of sulphur powders, 2.5 parts of accelerant CZs, 1.8 parts of altaxes, 50 parts of precipitated calcium carbonate, kerosene shale ash 20 parts of slag, 2 parts of beeswax；
Preparation method comprises the following steps：
The former ground-slag of oil shale waste slag after destructive distillation, that is, untreated, be broken to by step 1<300 mesh；By the former slag after crushing by solid Liquor ratio 1:5 ratio is added in Acidic NaCl Solution, and suspension is made under stirring, and suspension is added to electrolytic cell Middle electrolysis, metal is removed in the form of precipitating, specific device can refer to the mandate text of Patent No. 201710160505.8； Suspension is filtered to remove precipitation, adds after lye neutralizes and filters again, by much filtrate drying and dehydrating up to oil shale waste slag, institute State copper, cobalt, iron, nickel, titanium, the total content of vanadium in shale lime-ash additive（Summation including monomer and ionic state）Less than 5%；Its What Central Plains slag was selected is that the technique destructive distillation is complete, retort process temperature using the lime-ash of gained after Fushun type retort technique destructive distillation Degree is up to 600-800 degree, makes the impurity content in lime-ash few；Increasing of the oil shale waste slag as rubber is selected in instant component Strong agent, enhancing effect is good, and the intensity and hardness of product are high, and bearing capacity is strong, at the same substantially increase lime-ash using channel and Utility value, is no longer the raw material of the simple manufacture building materials of effect, but the reinforcing agent with actual functional capability uses, meaning weight Greatly；And the preparation process of oil shale waste slag is simple, without high-temperature firing again, energy conservation and environmental protection.
Step 2, add into natural rubber stearic acid, antiscorching agent, beeswax on double roller cylinder open mill it is thin it is logical plasticate 5 times, After uniform bag roller, sequentially add nano zine oxide, high wear-resistant carbon black, 50 parts of precipitated calcium carbonate, 20 parts of oil shale waste slag and mixed Refining, preliminary roller melting temperature are 62~68 DEG C, and back roller melting temperature is 58~62 DEG C, 2 mistake glue of feed rule, knife rule 2 of going further It is secondary, blanking slice, mixing time 180 seconds after being kneaded uniformly；
Step 3：Film made from mixing is put into vulcanizer, installs upper plate and lower plate, adds sulphur powder, vulcanization accelerator, 27~30min of atmospheric pressure vulcanization obtains required product at 170 DEG C~175 DEG C.
Preferably：The relation of temperature and time is in step 3：y=T0+(T-T0)Sin(0.5π*t0/t)；Y is the time in formula t0When temperature value, T0For room temperature, T is one in 170 DEG C~175 DEG C of the curing temperature such as present invention of setting, t0For Vulcanize the time carried out, t is the specific time such as 30min in 27~30min of vulcanization time such as the present invention program of setting. Vulcanization is to determine the key factor of rubber performance, and the present invention program overcomes technology prejudice, using the special side gradually heated up Formula is vulcanized, and the process time and the relation of temperature to heat up meets the portion waveshape of SIN function, and this programme is starting rank Duan Wendu is relatively low, whole process less energy intensive, is 60% or so under normal circumstances, and obtained product state of cure (vulcanization) is adapted to, Long-Term Properties change is small.
Preferably：The beeswax is natural beeswax, conventional method can be used to extract, such as Publication No. 201610374218.2 Patent application disclosed in method.Other each components are this area routine materials, can be as obtained by commercially available purchase.
After testing, using the method for the present invention, gained beam rubber, 23~25MPa of tensile strength, extension at break Rate 600~700%, shore hardness 72~82, has good fracture strength and elongation at break and higher hardness, compression is forever Long deflection 8~10%, rubber excellent in mechanical performance are adapted to heavy weight damping, and damping performance is good.It follows that this technology Recipe ingredient and method used by scheme, scorching quality is excellent, process safety, and manufacture cost is low, and resulting product has good Good fracture strength and elongation at break and higher hardness, be especially suitable for beam.
To sum up, the advantages of structure of the present invention has simple in structure, and cost is low, and bearing capacity is strong, and cushion performance is good, can be extensive Compartment damping for train.
