Abstract
The invention discloses a kind of formula of reamer bearing slat gum.Its component and mass percent are：60 ~ 70 parts of smoke sheet rubber；30 ~ 40 parts of butadiene-styrene rubber；8 ~ 10 parts of zinc oxide；1.6 ~ 2.2 parts of stearic acid；6 ~ 8 parts of tackifying resin；0.5 ~ 0.6 part of altax；0.7 ~ 0.8 part of accelerant CZ；1.5 ~ 2.0 parts of antioxidant 4020；1 ~ 1.5 part of microcrystalline wax；45 ~ 55 parts of carbon black N339；35 ~ 45 parts of carbon black N220；8 ~ 10 parts of aromatic naphtha；6 ~ 8 parts of sulphur.After above-mentioned component and formula, as long as using conventional material with regard to that can produce qualified bearing strip rubber product, not only its input cost is low, and hardness is high, anti-wear performance is good, abrasion is effectively reduced after use, in addition, ratio collocation rationally causes physical and mechanical properties to meet the requirements between various composition formulas, product is reliable and stable, with higher cost performance, yield rate is effectively guaranteed, and carries out trial assembly, and its size has also reached requirement with precision.
Description
Technical field
It is specifically a kind of the present invention relates to a kind of formula for the rubber product of reamer bearing protection on dredger
The formula of reamer bearing slat gum.
Background technology
Bearing holder (housing, cover) on dredger on reamer bearing is the operating for protecting bearing, reduces the part of abrasion, bearing
Set is assembled by one piece of block gum bearing strip in itself, has the performances such as detachable, anti-flattening, high abrasion, to size
Required precision it is also very high.
Bearing holder (housing, cover) is all supported the use in existing reamer equipment, existing bearing holder (housing, cover) because its formula is unreasonable, in order to
Meet its performance, generally require and place skeleton in single bearing strip（Steel part）To keep corresponding product hardness, arc
Degree, size, using existing this method, although certain protective action can be played, rubber hardness and yield rate are not
It can guarantee that, i.e., hardness reaches, there is also easy the defects of splitting, further, since the research and development technology of bearing holder (housing, cover) has office
It is sex-limited so that the cycle is long, and input is relatively large, in recent years in product and technology, bearing strip in user's always individual bank,
Therefore be badly in need of a kind of new formula meets its performance requirement to realize.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of anti-wear performance is good, input cost is low, high yield rate and product
The formula of reliable and stable reamer bearing slat gum.
In order to solve the above-mentioned technical problem, the formula of reamer bearing slat gum of the invention, its component and mass percent
For：60 ~ 70 parts of smoke sheet rubber；30 ~ 40 parts of butadiene-styrene rubber；8 ~ 10 parts of zinc oxide；1.6 ~ 2.2 parts of stearic acid；6 ~ 8 parts of tackifying resin；
0.5 ~ 0.6 part of altax；0.7 ~ 0.8 part of accelerant CZ；1.5 ~ 2.0 parts of antioxidant 4020；1 ~ 1.5 part of microcrystalline wax；Charcoal
Black 45 ~ 55 parts of N339；35 ~ 45 parts of carbon black N220；8 ~ 10 parts of aromatic naphtha；6 ~ 8 parts of sulphur.
Its component and mass percent are：65 parts of smoke sheet rubber；35 parts of butadiene-styrene rubber；9 parts of zinc oxide；1.9 parts of stearic acid；Increase
6.5 parts of viscosity resin；0.5 part of altax；0.8 part of accelerant CZ；1.7 parts of antioxidant 4020；1.3 parts of microcrystalline wax；Charcoal
Black 50 parts of N339；40 parts of carbon black N220；9 parts of aromatic naphtha；7 parts of sulphur.
The smoke sheet rubber is 3# smoke sheet rubbers.
After above-mentioned component and formula, as long as being produced using conventional material with regard to qualified bearing slat gum can be produced
Product, not only its input cost is low, and hardness is high, anti-wear performance is good, abrasion is effectively reduced after use, in addition, various compositions
Ratio collocation rationally causes physical and mechanical properties to meet the requirements between formula, and product is reliable and stable, has higher cost performance, into
Product rate is effectively guaranteed, and carries out trial assembly, and its size has also reached requirement with precision.
