Abstract
The invention belongs to the field of rubber and particularly relates to cold-resisting rubber. The cold-resisting rubber is prepared from the following materials: neoprene W, ethylene propylene rubber 1500, butadiene rubber CR1211, fluorosilicone rubber, semi-reinforcing furnace black SRF, microcrystalline wax, high styrene resin, magnesium oxide, sulfur, hard clay, fine-grain-diameter carbon black, light-weight operation oil, zinc oxide, N,N'-diaryl p-phenylenediamine, N-phenyl-N'-isopropyl p-phenylenediamine, stearic acid, phenol-formaldehyde resin and butyl oleate. The cold-resisting rubber has the beneficial effects that the rubber obtained by the formula has a good cold-resisting performance; after the rubber is stored at -40 DEG C and -50 DEG C for 3 months, the 200 percent definite elongation stress, the tensile strength and the elongation at break/percent variation range are relatively small; and the tensile strength retention rate and the retention rate of the elongation at break keep relatively good.
Description
Technical field
The invention belongs to rubber materials, be specifically related to a kind of arctic rubber.
Background technology
The physical and mechanical properties of rubber is affected very big by low temperature, be mainly manifested in hardening, become fragile, elasticity loss and other one
A little catabiosis so that it is initial quality reduces.The tolerance to cold of rubber, i.e. keeps its elastic and normal work in a low temperature of regulation
The ability made, the tolerance to cold of rubber depends primarily on two fundamental characteristics of high polymer, glass transition and crystallization, both can
Rubber is made to lose elasticity at low temperatures.The motor capacity that the tolerance to cold of rubber is mainly reflected in strand is relatively strong, intermolecular fortune
Dynamic relative easy, relative low of the energy of molecule cohesion.
Use under conditions of rubber mostly cannot adapt to low temperature at present, and long-term rubber under cryogenic,
The change of its stress at definite elongation generation large change amplitude, the holding of its stretching strength retentivity, elongation at break conservation rate is poor, nothing
Method meets use demand.
Accordingly, it would be desirable to the shortcoming for rubber tolerance to cold difference improves, overcome its shortcoming, to improve its cold tolerance.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides the rubber that a kind of cold tolerance is good, this rubber is-40
DEG C ,-50 DEG C preserve after 3 months, its 200% stress at definite elongation, hot strength, elongation at break amplitude of variation are smaller;It draws
Stretch strength retention, elongation at break conservation rate keeps preferably.
The arctic rubber of the present invention, including the material of following parts by weight:
A kind of arctic rubber, including the material of following parts by weight:
Preferably, above-mentioned arctic rubber, including the material of following parts by weight:
It is furthermore preferred that above-mentioned arctic rubber, including the material of following parts by weight:
Above-mentioned rubber also includes ethylene propylene rubber latex 1-4 weight portion.
The parts by weight of above-mentioned ethylene propylene rubber latex are 3 parts.
Above-mentioned rubber also includes thiuram 0.5-3 part.
As a modification of the present invention, above-mentioned rubber includes the component of following portions by weight:
Above-mentioned rubber includes acrylonitrile compolymer-hydrolysis high water-absorption fiber 0.01-0.2 part.
Add after natural rubber such as EP rubbers, butadiene rubber, greatly improved its cold tolerance, but its oil resistivity
Can reduce with anti-wear performance, therefore, present invention employs neoprene W, EP rubbers 1500, butadiene rubber CR1211, fluorine silicon
Rubber these four size composition, and add adjuvant phenol formaldehyde resin, ethylene propylene rubber latex, make the sizing material of the present invention not only have relatively
Good resistance to low temperature, and do not affect its oil resistivity.
The beneficial effects of the present invention is, use the sizing material that the formula of the present invention obtains, its cold tolerance is good ,-40
DEG C ,-50 DEG C preserve after 3 months, its 200% stress at definite elongation, hot strength, elongation at break amplitude of variation are smaller;It draws
Stretch strength retention, elongation at break conservation rate keeps preferably.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described, in order to those skilled in the art knows more about
The present invention, but and it is not so limited the present invention.
Embodiment 1
Arctic rubber is made up of the component of following parts by weight:
Above-mentioned rubber just process after be placed in 40 degrees below zero and subzero 50 degree deposit three months after, its Performance comparision is such as
Under:
Just after processing | Deposit three months for subzero 40 DEG C | Deposit three months for subzero 50 DEG C | |
200% stress at definite elongation/0.1MPa | 79 | 90 | 91 |
Hot strength/0.1MPa | 140 | 135 | 132 |
Elongation at break/% | 430 | 403 | 395 |
Stretching strength retentivity/% | / | 96 | 94 |
Elongation at break conservation rate/% | / | 94 | 92 |
From data above it can be seen that the arctic rubber of the present invention subzero 40 DEG C, subzero 50 DEG C deposit three months after,
Its 200% stress at definite elongation/0.1MPa, hot strength/0.1MPa, elongation at break/% amplitude of variation is smaller;
Its stretching strength retentivity/%, elongation at break conservation rate/% keeps preferably.
Embodiment 2
Arctic rubber is made up of the component of following parts by weight:
Embodiment 3
Arctic rubber is made up of the component of following parts by weight:
Embodiment 4
Arctic rubber is made up of the component of following parts by weight:
The production method of epoxy resin adhesive is as follows:
By equal for 1mol tri-benzene three formyl and 3mol epoxy chloropropionate alcohol under the effect of catalyst of triethylamine, carry out at 5 DEG C
Reaction, synthesizes trimesic acid three-glycidyl ester;Be sequentially added into 100kg trimesic acid glycidic alcohol, 15kg butyronitrile-40,
12kg firming agent (α-ethyl-4-methylimidazole) and 30kg filler-calcium carbonate, be mixed uniformly, obtain epoxy resin gluing
Agent.
Comparative example 1
With not being both of embodiment 4, do not add acrylonitrile compolymer-hydrolysis high water-absorption fiber;Remaining is identical;
Comparative example 2
With not being both of embodiment 4, do not add epoxy resin adhesive;Remaining is identical;
Performance comparison is as follows:
Embodiment 4 | Comparative example 1 | Comparative example 2 | |
200% stress at definite elongation/0.1MPa | 76 | 71 | 69 |
Hot strength/0.1MPa | 145 | 136 | 132 |
Elongation at break/% | 440 | 435 | 421 |
Be respectively placed in-50 DEG C deposit 6 months after, its performance test is as follows:
Embodiment 4 | Comparative example 1 | Comparative example 2 | |
200% stress at definite elongation/0.1MPa | 79 | 65 | 62 |
