Description
Technical field
The present invention relates to automobile manufacturing field, is a kind of rubber fixed block composition spacing for automotive hose specifically.
Background technology
Along with the develop rapidly of automotive industry, the design of part of automotive interior becomes increasingly complex, and the connectivity problem between each parts occurs thereupon, and rubber hose is connected with other system the bridging mode all using clip.Along with the continuous upgrading of motor car engine performance and the progressively application of turbocharging technology, temperature requirement and the pressure of automotive hose inside also improve constantly, the connection of usual Sebific duct hoop is installed by artificial end position clip being chosen at random sebific duct, the startup optimization of simultaneous engine, the past renaturation motion of temperature and pressure, cause existing after for some time because clip installation site unfixing or not in the region of specifying running, cause clip and flexible pipe to produce displacement and cause connecting portion or system to exist to leak or the hidden danger of seepage.Along with the generation of this phenomenon, current design engineer is at the coloured telltale mark line of the end of flexible pipe design band, occur with the phenomenon of pre-antiseep and leakage to be used for the installation site of spacing control clip, but along with vibration and the installation artificial in enormous quantities of engine, the shift phenomenon of clip installation site is caused to happen occasionally, for the generation of stopping this phenomenon completely adopts the integrated block rubber composition of injection to form stop zone, clip is caused to produce skew thoroughly to prevent the defective mounting of workman.So develop a kind of rubber fixed block composition spacing for automotive hose, misplacing to preventing clip and offset causes the phenomenon of seepage and leakage to be of great significance.
Summary of the invention
The object of this invention is to provide a kind of rubber fixed block composition spacing for automotive hose, the composition of the automotive hose limited block using styrene-butadiene rubber(SBR) and terpolymer EP rubber reclaimed rubber to develop for main body has the feature such as good thermotolerance, low temperature resistant, wear-resisting, weather, resistance to ozone, resistance to be full of cracks.The limited block using said composition to make has excellent thermotolerance, ozone resistance, wear resistance and weathering resistance.
Technical scheme of the present invention is as follows: this is used for the spacing rubber fixed block composition of automotive hose, is made up of following component:
Styrene-butadiene rubber(SBR) 60 ~ 80 weight part;
Terpolymer EP rubber reclaimed rubber 80 ~ 100 weight part;
Zinc oxide 2 ~ 5 weight part;
Stearic acid 1 ~ 2.0 weight part;
Ancient Malong 2 ~ 3 weight part;
2,2,4-trimethylammonium-1,2-dihyaroquinoline 1 ~ 2.0 weight part;
N, N-bis-(betanaphthyl) Ursol D 0.2 ~ 1 weight part;
Carbon black N550 50 ~ 70 weight part;
High abrasion N330 50 ~ 70 weight part;
Fine particle calcium carbonate 30 ~ 50 weight part;
Naphthenic oil 40 ~ 60 weight part;
1,3-vulkacit D 0.2 ~ 0.5 weight part;
2,2'-dithio-bis-benzothiazole 1 ~ 2.0 weight part;
Tellurium diethyl dithiocarbamate 0.5 ~ 1.0 weight part;
Sulphur 0.5 ~ 1.0 weight part.
In formula, 2,2,4-trimethylammonium-1,2-dihyaroquinoline and N, N-bis-(betanaphthyl) Ursol D are as anti-aging agent; 2,2 '-dithio-bis-benzothiazole, tellurium diethyl dithiocarbamate, 1,3-vulkacit D are as promotor.
Styrene-butadiene rubber(SBR) and Ethylene Propylene Terpolymer reclaimed rubber is selected to make product obtain higher tensile strength, better tensile yield and wear resistance, excellent resistance toheat and low-temperature performance.Rubber is enable to meet the requirement of heat-resistant aging, resistance to weather, ozone resistance, wear resistance, flexible resistance and lower temperature resistance.
2,2,4-trimethylammonium-1,2-dihyaroquinoline (anti-aging agent KY-124) is pale powder, and fusing point is 114 DEG C.Not easily bloom is on vulcanization crosslinking process without impact, nontoxic.N, N-bis-(betanaphthyl) Ursol D (antioxidant D NP) is splitting of chain inhibitor, it is again metal chelating agent, there is the effect of the poisonous metals such as excellent heat-proof aging, resistance to natural weathering and anti-copper, manganese, metal clip can be suppressed the corrosive nature of the spacing fixed block of rubber that rubber combination is made.Also can improve UV resistance characteristic in butadiene-styrene rubber, jointly use with thiazole accelerator DM simultaneously, also have obvious activation, improve the crosslinking degree of product.Anti-aging agent KY-124 and antioxidant D NP use, can make product have excellent thermotolerance, ozone resistance, resistance to weather, simultaneously to flex crack, also have stronger protective effect.
Naphthenic oil can make product have excellent thermotolerance and good photostabilization, improves plasticity and the toughness of material, improves consistency.Naphthenic oil has saturated cyclic carbon-chain structure; there is low pour point; high-density, high viscosity, the feature such as have no side effect; its ring also can be connected to saturated side chain usually; containing extremely low polar material content, effectively prevent the fading of the oil extend rubber goods that these materials cause, situation that is aging and polymkeric substance be full of cracks under sun exposure.2,2 '-dithio-bis-benzothiazole (altax) and tellurium diethyl dithiocarbamate (promotor TDEC) directly can add rubber and not cause incipient scorch, and vulcanization rate is fast, improve degree of crosslinking, increase tensile strength, improve material thermal resistance, wear resistance, weathering resistance and ozone resistance.Promotor TDEC have do not dye, pollution-free, can be used as a kind of endless vulcanization primary accelerator use.Altax can improve the sulfurate activity of Ethylene Propylene Terpolymer reclaimed rubber, improves the inter-vulcanizability of reclaimed rubber and butadiene-styrene rubber, thus improves physical and mechanical properties and the solvent resistance of integrally combined thing.
Embodiment
Content of the present invention is described in detail below by way of specific embodiment.It is below the consumption of each component in embodiment 1 ~ 3
Unit: kg
Make film by starting material in implementation column formula and carry out testing inspection, each embodiment performance comparison is as follows:
Can be drawn by the data of upper table, the rubber fixed block composition original performance spacing for automotive hose is better, hot air aging resistance is better, low temperature brittleness is excellent, resistance to cooling is also excellent, use under can meeting the low temperature environment of different areas in the winter time, the performance of wear resistance and warping strength be full of cracks simultaneously also improves the work-ing life of product very well.Automotive hose functionalization and spacing requirement can be better met for the rubber fixed block composition that automotive hose is spacing, may be used for automobile cooling system flexible pipe, prime the fuel system flexible pipe be arranged the rubber fixed block that territory, clip attachment area is spacing.
