Abstract
The invention discloses a shock-reducing rubber, and relates to the technical field of rubber product manufacture. The shock-reducing rubber is prepared from the following raw materials in parts by weight: 90-100 parts of chloroprene rubber, 5-8 parts of zinc oxide, 1-1.5 parts of stearic acid, 0.7-1 part of accelerants M, 2-3 parts of anti-aging agents A, 1-2 parts of anti-aging agents 4010 NA and 30-40 parts of carbon black. The shock-reducing rubber disclosed by the invention has the advantages of high-elasticity state, high-viscosity state, good shock-reducing property, sound-insulating property and buffer property, good heat resistance and fatigue resistance, low possibility in aging and long service life.
Description
Technical field
The present invention relates to rubber item manufacturing technology field, especially a kind of rubber for damping.
Background technology
Yielding rubber is widely used in lathe, effects such as reducing vibration, sound insulation, buffering is worked at each position of vehicle, requires that damping property, thermotolerance and resistance to fatigue are good.The yielding rubber thermotolerance of current use and resistance to fatigue are not good, easy premature aging, cause yielding rubber to lose efficacy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of yielding rubber, with solve existing yielding rubber thermotolerance and resistance to fatigue not good, easily aging problem.
In order to solve the problem, the technical solution used in the present invention is: the raw material that this yielding rubber includes following weight part is made: chloroprene rubber 90 parts ~ 100 parts, 5 parts ~ 8 parts, zinc oxide, stearic acid 1 part ~ 1.5 parts, captax are 0.7 part ~ 1 part, antioxidant A is 2 parts ~ 3 parts, antioxidant 4010NA is 1 part ~ 2 parts, carbon black 30 parts ~ 40 parts.
Described chloroprene rubber is chloroprene (i.e. chlorbutadiene) is the synthetic rubber that main raw material carries out α-polymerization and manufacture, and have good physical and mechanical properties, have higher tensile strength, elongation and reversible crystallinity, cementability is good; It is ageing-resistant, heat-resisting, oil resistant, resistance to chemical corrosion excellent.
Described zinc oxide is conventional chemical additive, is mainly used in rubber or cable industry makes strengthening agent and promoting agent, also makes tinting material and the weighting agent of white size, in chloroprene rubber, is used as vulcanizing agent.
Described stearic acid, is the vulcanization leveller of widespread use in natural gum, synthetic rubber and latex, also can be used as softening agent and tenderizer; Stearic acid also can be used as the releasing agent of rubber item.
Described captax, be a kind of main sour sulfur agent, its curing temperature is low, easily disperses, do not pollute, mainly for the manufacture of tire, adhesive tape and other industrial rubber articles in rubber.
Described antioxidant A, it is aromatic amine class anti-aging agent, for natural rubber, diene-based synthetic rubber, chloroprene rubber, it is the universal anti-aging agent of reclaimed rubber, to heat, oxygen, subdue, Weather, fatigue has good protective effect, in chloroprene rubber, have the performance that ozone-resistant is aging concurrently, also have certain restraining effect to poisonous metal.
Described antioxidant 4010NA is the efficient anti-aging agent of one, for effective especially in natural rubber and other rubber, has remarkable barrier propterty to the fatigue that deflects that ozone, wind erosion and mechanical stress cause.
Described carbon black is a kind of decolorizing carbon, light, loose and superfine black powder, and surface-area is very large, is the product that carbonaceous material obtains through incomplete combustion or decomposes under the condition of lack of air, as the strengthening agent of rubber.
The existing elastomeric state of yielding rubber of the present invention has again high glutinous state, has good damping, sound insulation and shock-absorbing capacity, thermotolerance and resistance to fatigue good, be not easy aging, long service life.
