Abstract
The invention provides a formula of a seamless connection ethylene propylene diene monomer foaming connecting corner. The formula of the seamless connection ethylene propylene diene monomer foaming connecting corner is characterized in that the formula comprises the following materials in parts by mass: 80 to 110 parts of ethylene propylene diene monomer, 30 to 45 parts of N550 carbon black, 30 to 55 parts of N774 carbon black, 50 to 65 parts of paraffin oil, 5 to 15 parts of zinc oxide, 1 to 5 parts of stearic acid, 0.5 to 3.5 parts of sulfur, 3 to 5 parts of an accelerant, 3 to 7 parts of a micro-foaming agent and 2 to 7 parts of a blending agent. 4010-X raw rubber with ultralow mooney and imported from Japan is adopted, mixed rubber has ultralow mooney and excellent flowability, seamless connection can be realized, the connecting corner strength is high, a micro-foaming agent product does not have bubbles on the surface, the specific gravity is reduced, and the weight of a whole vehicle can be reduced.
Description
Technical field
The present invention relates to rubber manufactures field, more particularly to a kind of slitless connection ethylene propylene diene rubber foaming connects angle formula.
Background technology
At present when manufacture foaming connects angle, general expanded material is usually used and prepares, but general expanded material system
Standby connects angle illiquidity, causes to connect angle and easily there is gap when in use, and impact connects the connection effect at angle, and general
Expanded material easily produces bubble in foaming, causes to connect angle quality damage, connects angle service life not enough.Therefore, foaming is solved
The problem that manufacture connects the illiquidity brought at angle and easily produces bubble is just particularly important.
The content of the invention
For the problem that above-mentioned prior art is present, it is an object of the invention to provide a kind of slitless connection ethylene propylene diene rubber
Foaming connects angle formula, by ethylene propylene diene rubber, N550 white carbon blacks, N774 white carbon blacks, paraffin oil, Zinc Oxide, stearic acid, sulfur, rush
That enters that agent, fine foamer and blender produce ethylene propylene diene rubber foaming connects angle, solves foaming manufacture and connects the stream that angle is brought
Dynamic property is not enough and easily produces the problem of bubble.
The present invention provides a kind of slitless connection ethylene propylene diene rubber foaming and connects angle formula, the mass fraction of the formula materials
For 80 ~ 110 parts of ethylene propylene diene rubber, 30 ~ 45 parts of N550 white carbon blacks, 30 ~ 55 parts of N774 white carbon blacks, 50 ~ 65 parts of paraffin oil, Zinc Oxide 5 ~
15 parts, 1 ~ 5 part of stearic acid, 0.5 ~ 3.5 part of sulfur, 3 ~ 5 parts of accelerator, 3 ~ 7 parts of fine foamer, 2 ~ 7 parts of blender.
Further improvement is that：The mass fraction of the formula materials be 100 parts of ethylene propylene diene rubber, N550 white carbon blacks 40
Part, 40 parts of N774 white carbon blacks, 60 parts of paraffin oil, 6 parts of Zinc Oxide, 1 part of stearic acid, 0.8 part of sulfur, 5 parts of accelerator, fine foamer 4
Part, 3 parts of blender.
Further improvement is that：The ethylene propylene diene rubber is ethylene propylene diene rubber 4010-X rubbers.
Further improvement is that：The accelerator is accelerator NS.
The invention has the beneficial effects as follows：Using the 4010-X rubbers of the Japanese import of ultra-low Mooney, elastomeric compound Mooney is ultralow,
Mobility is splendid, is capable of achieving slitless connection, connects that angle intensity is high, and using fine foamer product surface bubble-free, proportion is reduced, can be with
Reduce complete vehicle weight.
