Embodiment 1

[0098]The branched polyethylene numbered is Per-9.

[0099]The processing steps of the test rubber composition are as follows:

[0100](1) Rubber kneading: Set the intact machine temperature of 100 ° C, the rotor rotation speed is 50 rpm, add 90 parts of three-membered ethylene ethylene rubber and 10 partial branching polyethylene preloading for 90 seconds; 5 parts of oxidation Zinc, 0.2 kinds of stearic acid, 1 anti-aging agent RD, mixed for 1 minute; then add 60 carbon black N330, 25 parts of paraffin oil in the rubber, mixed for 3 minutes; finally add 5 crosslinking agents Oxide oxide (DCP), 1 part guaranteed tri-propyl isocyanurate (TAIC), mixed 2 minutes after pulling, the mixture is on the open mill of 60 ° C Thin Tong, get 2.5mm thick thin film, park for 20 hours

[0101](2) After 16 hours after vulcanization, various tests were performed.

Embodiment 2

[0103]The branched polyethylene numbered is Per-8.

[0104]The processing steps of the test rubber composition are as follows:

[0105](1) Rubber kneading: The mesh temperature is 90 ° C, the rotor speed is 50 rpm, and 80 parts of three-membered ethylene ethylene rubber and 20 parts of branching polyethylene prematch mixed 90 seconds; 10 part yet Zinc and 2 stearic acids, mixing for 1 minute; then 80 copper black N330, 25 servile oil Sunpar2280, mixed for 3 minutes; finally add 1 crosslinking agent peroxide dipropate ( DCP), 0.5 part of the crosslinker sulfur, 1.5 servuliosulfur disulfide tetramethyl Qalanm and 1 vulcanization promoter, a vulcanized trimethyl Qalaum, mixed 2 minutes post-plastic glue, mixed rubber Thin is thin on the open mill at 60 ° C to give a sheet of about 2.5 mm thickness, and is parked for 20 hours.

[0106](2) After 16 hours after vulcanization, various tests were performed.

Embodiment 3

[0108]The branched polyethylene numbered is Per-5.

[0109]The processing steps of the test rubber composition are as follows:

[0110](1) Rubber kneading: Set the intact machine temperature of 100 ° C, the rotor speed is 50 rpm, add 20 parts of binary ethylene ethylene ethylene ethylene ethylene ethylene rubber and 30 parts of branch polyethylene preload mix 90 seconds; 15 parts of zinc oxide, 3 parts magnesium oxide, 3 stearic acids, 1 anti-aging agent RD, mix for 1 minute; then add 50 carbon black N330, 10 servile oil Sunpar2280, Mix for 3 minutes; finally add 6 crosslinking agents peroxide (DCP), 2 partial agent tri-propyl isocyanurate (Taic), blending 2 minutes after gum, will The mixture is thin on the opening mill at 60 ° C, resulting in a sheet having a thickness of about 2.5 mm, parked for 20 hours.

[0111](2) After 16 hours after vulcanization, various tests were performed.

Abstract

The invention discloses a rubber composition, which comprises the following parts by weight: 100 parts of rubber matrix, wherein the content of branched polyethylene is a: 0<a≤100 parts, binary ethylene propylene rubber and ethylene propylene terpolymer The total content of rubber b: 0≤b<100 parts; cross-linking agent: 1.5-9 parts; auxiliary cross-linking agent: 0.2-9 parts; reinforcing filler: 40-170 parts; plasticizer: 6-93 parts; Metal oxide: 3-25 parts; the technical effect of the present invention is to provide a rubber composition with excellent heat resistance and mechanical properties, which can be used for conveyor belt covering rubber.

Description

Technical field[0001]The present invention belongs to the field of rubber technology, and more particularly to a rubber composition, and a method of processing thereof, further involves a conveyor belt using the rubber composition, and a method of producing a conveyor belt.Background technique[0002]The conveyor belt used in high temperature environments, in order to partially use a good thermal resistance in the formula formula of each portion of the conveyor resistance (especially the cover layer of the material directly in contact with the material) in order to meet the high temperature resistance of high temperature resistance. C rubber. However, this low intensity is used in a large amount of binary ethylene ethylene rubber using a tensile strength of ethylene rubber or natural rubber, in particular in order to satisfy better heat resistance. The defect is more obvious. Therefore, the application range of such heat-resistant conveyor belts is limited to the coverage of the heat-...
