Definitions
- Cross-linking performance includes factors such as crosslink density and cross-linking rate, which is the specific performance of the cross-linking ability of the rubber matrix during processing.
- the vinyl copolymer refers to a copolymer of ethylene and a branched ⁇ -olefin, and has a secondary branched structure, wherein the branched ⁇ -olefin may be selected from the group consisting of isobutylene and 3-methyl-1- Butylene, 4-methyl-1-pentene, 3-methyl-1-pentene, 2-methyl-1-heptene, 3-methyl-1-heptene, 4-methyl-1- The heptene, 5-methyl-1-heptene, 6-methyl-1-heptene, and the like, the comonomer may also contain a common linear alpha-olefin.
- a further preferred technical solution for the branched polyethylene is a branching degree of 80 to 105 branches/1000 carbons, a weight average molecular weight of 250,000 to 400,000, and a Mooney viscosity of ML (1+4) of 125 ° C of 40 ⁇ . 95.
- a further technical solution is that the amount of carbon black is from 30 to 60 parts by weight based on 100 parts by weight of the rubber base.
- the above-mentioned carrier core wire is subjected to a bonding treatment to improve the adhesion property of the carrier core wire to the rubber, and the bonding can be performed by dipping the carrier core wire into a treatment solution such as resorcinol formaldehyde latex (PFL impregnation liquid) and heating and drying. .
- a treatment solution such as resorcinol formaldehyde latex (PFL impregnation liquid) and heating and drying.
- the branched polyethylene used was numbered PER-7.
- Rubber mixing set the temperature of the mixer to 90 ° C, the rotor speed is 50 rpm, add 100 parts of EPDM rubber, pre-press and knead for 90 seconds; add 6 parts of zinc oxide, 1 part of stearin Acid, 2 parts of antioxidant RD, kneaded for 1 minute; then add 45 parts of carbon black N330, 5 parts of paraffin oil SUNPAR2280 and 5 parts of coumarone resin in the compound, mix for 3 minutes; then add 20 parts of length 1mm Nylon staple fiber, kneaded for 2 minutes; finally add 4 parts of cross-linking agent dicumyl peroxide (DCP) and 1.5 parts of cross-linking agent triallyl isocyanurate (TAIC), mixing for 2 minutes After the rubber is glued, the rubber compound is thinly passed on the open mill with a roll temperature of 80 ° C, and is thinned 7 times at a roll gap of 0.5 mm to fully orient the short fibers, and the roll gap is obtained to obtain a
- the above rubber mixture is placed in a screw extruder for hot refining, and then supplied to a calender for calendering to be used.
- a calender for calendering to be used.
- the thickness of the film is controlled at 4.5 to 12 mm, and it is kept warm after use.
- the aramid staple fibers in the rubber compound are longitudinally aligned.

- the rubber substrate used in Example 22 was 100 parts of PER-12, and the rubber substrate used in Example 23 was 50 parts of PER-12 and 50 parts of ethylene propylene diene monomer (ML (1+4) 125 ° C was 60, and the ethylene content was 68. %, ENB content 4.8%), the rubber substrate used in Comparative Example 3 was 100 parts of the ethylene propylene diene rubber used in Example 23. The rest of the formula is consistent.
- Example 22 has the shortest Tc90, which is about 25% shorter than that of Comparative Example 3, and the MH-ML values are very close, indicating that the branched polyethylene used in this embodiment can be superior to the conventional ternary in cross-linking ability.
