Abstract
The invention discloses a kind of nitrile rubbers of rubber buffer washer high-hardness high-rebound performance, it is made by the raw material of following weight parts: nitrile rubber 60-70, PVC 6-18, diamond dust 2-4, attapulgite 16-18, sodium metasilicate 2-4, N, N- dimethyl lauramide 0.3-0.5, choline 0.2-0.4, antioxidant 264 1-2, epoxidized linseed oil 1-2, stearic acid 1-2, magnesia 1-2, Vulcanization accelerator TMTD 1-2, sulphur 2-5.The present invention is guarantee high resilience energy and high-durability energy, plus PVC progress and remaining raw material, the rebound and endurance quality of guarantee gained rubber material in conventional rubber performance.
Description
Technical field
The present invention relates to CABLE MATERIALS fields, are exactly a kind of fourths of rubber buffer washer high-hardness high-rebound performance
Nitrile rubber.
Background technique
Damper be for inhibit after spring shock-absorbing rebound when concussion and from the impact on road surface.He is widely used in
Automobile, for accelerate vehicle frame and body vibrations decaying, to improve ride of vehicle.When by uneven road surface, although
Shock-absorbing spring can filter the vibration on road surface, but spring itself also has reciprocating motion, and damper is exactly for inhibiting this
Spring jump.
Rubber buffer washer is assemblied on piston lever of reducer, plays the effect of damping, since the product rubber volume is small,
But the power being subject to is very big, and is pressurized repeatedly, so, it is desirable to the product has very high hardness and resilience, and rubber
The endurance quality being pressurized repeatedly wants high.Very high requirement is provided to design for rubber formulation.Nitrile rubber is by butadiene and third
For alkene nitrile through made from emulsion polymerization, nitrile rubber mainly uses emulsion polymerization at low temperature to produce, oil resistivity is fabulous, wearability compared with
Height, heat resistance is preferable, and bonding force is strong, however the hardness of nitrile rubber is difficult to meet the needs of buffer gasket, is badly in need of a kind of high hard
The nitrile rubber of the high rebound of degree.
Summary of the invention
The purpose of the present invention is to provide a kind of nitrile rubbers of rubber buffer washer high-hardness high-rebound performance.
Above-mentioned purpose is realized by following scheme:
A kind of nitrile rubber of rubber buffer washer high-hardness high-rebound performance, which is characterized in that it is by following heavy
The raw material for measuring part is made: nitrile rubber 60-70, PVC 6-18, diamond dust 2-4, attapulgite 16-18, sodium metasilicate 2-4, N, N-
Dimethyl lauramide 0.3-0.5, choline 0.2-0.4, antioxidant 264 1-2, epoxidized linseed oil 1-2, stearic acid 1-2, magnesia
1-2, Vulcanization accelerator TMTD 1-2, sulphur 2-5.
A kind of nitrile rubber of rubber buffer washer high-hardness high-rebound performance, it is characterised in that: preparation side
Method the following steps are included:
(1) by diamond dust, attapulgite, sodium metasilicate, N, N- dimethyl lauramide, choline after evenly mixing, add appropriate
Water is chopped the chop, dry, then after Muffle furnace high temperature sintering 1-2h after natural cooling, it is spare to obtain modified filler for ball milling；
(2) nitrile rubber and modified filler, antioxidant 264 and epoxidized linseed oil are kneaded, obtain nitrile rubber mother
Refining glue；
(3) by nitrile rubber masterbatch in addition to sulphur remaining raw material after mixing, carry out mixing, add sulphur
Carry out mill to get.
A kind of nitrile rubber of rubber buffer washer high-hardness high-rebound performance, it is characterised in that: step (1)
In drying refer to 90-100 DEG C of dry 1-3h.
A kind of nitrile rubber of rubber buffer washer high-hardness high-rebound performance, it is characterised in that: step (1)
The temperature of middle Muffle furnace high temperature sintering is 200-500 DEG C.
The invention has the benefit that
First, for the oil resistance for guaranteeing product, rubber substrate selects the superior nitrile rubber of oil resistance, rubber raw rubber
Select the nitrile rubber raw rubber kind of external import；
Second, to guarantee that the rigidity property of product is met the requirements, the hardness of rubber first has to meet, therefore is added to modification
Filler is first chopped the chop and is sintered afterwards, the cellular porous form on its surface of resulting material and internal display macroscopic view, after grinding diamond dust and
Attapulgite compatibility is good, can increase hardness using diamond dust and guarantee the resilience of sizing material using attapulgite；
Third, for guarantee high resilience can and high-durability energy, carry out in conventional rubber performance plus PVC and its
Remaining raw material guarantees the rebound and endurance quality of gained rubber material.
Specific embodiment
A kind of nitrile rubber of rubber buffer washer high-hardness high-rebound performance, is by the raw material of following weight (kg)
It is made: nitrile rubber 60, PVC 8, diamond dust 2, attapulgite 16, sodium metasilicate 2, N, N- dimethyl lauramide 0.5, choline
0.4, antioxidant 264 2, epoxidized linseed oil 1, stearic acid 1, magnesia 1, Vulcanization accelerator TMTD 1, sulphur 2.
A kind of nitrile rubber of rubber buffer washer high-hardness high-rebound performance, preparation method includes following step
It is rapid:
(1) by diamond dust, attapulgite, sodium metasilicate, N, N- dimethyl lauramide, choline after evenly mixing, add appropriate
Water is chopped the chop, 100 DEG C of dry 3h, then after 300 DEG C of high temperature sintering 2h of Muffle furnace after natural cooling, it is spare to obtain modified filler for ball milling；
(2) nitrile rubber and modified filler, antioxidant 264 and epoxidized linseed oil are kneaded, obtain nitrile rubber mother
Refining glue；
(3) by nitrile rubber masterbatch in addition to sulphur remaining raw material after mixing, carry out mixing, add sulphur
Carry out mill to get.
