Abstract
The invention discloses a rubber with magnetism, and relates to the technical field of rubber. The method comprises the following raw materials in parts by weight: 100 parts of ethylene-propylene methylene copolymer, 13-20 parts of soft magnetic ferrite, 7-10 parts of calcium carbonate, 6-16 parts of high wear-resisting carbon black, 6-16 parts of spray carbon black, 2-8 parts of dithiocar-bamate, 2-5 parts of polyethylene wax, 3-15 parts of paraffin wax and 5.6-9 parts of vulcanized resin. Through the adoption of the rubber, the problem that the existing rubber is bad in elasticity, capable of separating from a sealing component and bad in sealing effect is solved.
Description
Technical field
The present invention relates to field of rubber technology, especially the magnetic rubber of a kind of band.
Background technology
Rubber is widely used in the sealing member of each web member of automobile as a kind of resilient material, section force of compression is given to cushion rubber realize sealing because the work of rubber seal to be contacted with by sealing member by rubber, and sealing member also will bear the to-and-fro movement of parts, therefore, after this type of current rubber seal often runs into and uses for some time, caoutchouc elasticity is poor, produce and be separated with sealing member, the problem of sealing effectiveness difference, therefore provide a kind of tool magnetic, the automobile rubber seal of the good sealing effect that better can be combined with parts is the problem that those skilled in the art need solution badly.
Summary of the invention
Technical problem to be solved by this invention is to provide the magnetic rubber of a kind of band, and it is poor that it can solve existing caoutchouc elasticity, produces and be separated with sealing member, the problem of sealing effectiveness difference.
In order to solve the problem, technical scheme of the present invention is: the magnetic rubber of this band, adopts the raw material of following weight part:
Ethylene propylene rubber: 100 parts; Soft magnetic ferrite: 13 parts to 20 parts; Calcium carbonate: 7 parts to 10 parts; High wear-resistant carbon black: 6 parts to 16 parts; Spray carbon black: 6 parts to 16 parts; Dithiocar-bamate: 2 parts to 8 parts; Polyethylene wax: 2 parts to 5 parts; Paraffin: 3 parts to 15 parts; Curing resin: 5.6 parts to 9 parts.
In technique scheme, scheme can also be more specifically: the magnetic rubber of described band, adopts the raw material of following weight part:
Ethylene propylene rubber: 100 parts; Soft magnetic ferrite: 15 parts to 18 parts; Calcium carbonate: 8 parts to 9 parts; High wear-resistant carbon black: 8 parts to 13 parts; Spray carbon black: 8 parts to 13 parts; Dithiocar-bamate: 4 parts to 6 parts; Polyethylene wax: 2 parts to 4 parts; Paraffin: 5 parts to 10 parts; Curing resin: 6.6 parts to 8 parts.
Further: the magnetic rubber of described band, adopts the raw material of following weight part:
Ethylene propylene rubber: 100 parts; Soft magnetic ferrite: 16 parts; Calcium carbonate: 8 parts; High wear-resistant carbon black: 10 parts; Spray carbon black: 10 parts; Dithiocar-bamate: 5.5 parts; Polyethylene wax: 3 parts; Paraffin: 8 parts; Curing resin: 7.3 parts.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, be that major ingredient rubber has high temperature resistance and alkaline-resisting, oil resistant, water-fast, ageing-resistant long service life feature owing to have employed ethylene propylene rubber.Due to adopt polyethylene wax as protective agent, can improve external tube layer rubber persistency, hardness and abrasion resistance;
2, the rubber making to produce owing to adding soft magnetic ferrite is provided with magnetic;
3, owing to adopting high wear-resistant carbon black and spray carbon black and use, make rubber physical mechanical property excellent, tensile set is little.
