Abstract
The invention relates to a conveying belt taking a polyester fiber as a skeleton. The conveying belt is characterized by comprising a belt body formed through molding crude rubber, cut aromatic polyamide fibers which are oriented along a preset direction of the belt body are mixed in top rubber and bottom rubber of the belt body, and cut polyester fibers which are oriented along the preset direction of the belt body are mixed in the belt body, wherein the cut polyester fibers are longer than the cut aromatic polyamide fibers, the length of the cut aromatic polyamide fibers is less than 5 mm, the length of the cut polyester fibers is more than 5 mm and less than 10 mm, and the rubber component of the crude rubber is one of ethylene-propylene copolymer, ethylene propylene diene terpolymer, nitrile rubber, hydrogenated nitrile rubber and chloroprene rubber. The conveying belt taking the polyester fiber as the skeleton has the beneficial effects that the cut aromatic polyamide fibers and the cut polyester fibers longer than the cut aromatic polyamide fibers are mixed in the crude rubber, in such a way, almost all the cut polyester fibers and cut aromatic polyamide fibers are oriented along a rolling direction, so that the durability of the conveying belt is improved.
Description
Technical field
The present invention relates to a kind of line belt take polyester fibre as skeleton.
Background technique
Existing vehicle generally at high temperature uses with driving belt, and bears the high pressure on the width direction during operation.Therefore, this driving belt is made by chloroprene rubber, and it has higher heat resistance, and has mixed the contraposition aromatic polyamide fibers of cut-out and broad ways orientation in this vee belt, thereby improves this with the intensity of relevant side pressure.Thus, the serviceability of driving belt is improved to a certain degree.Yet if be subject to more high pressure at the width direction of transport tape, this serviceability is still not enough.Therefore, propose, the cut-out aromatic polyamide fibers that is mixed in the band should be longer, in order to improve the orientation characteristic, and further improves the serviceability of line belt.Yet the modulus of the polyamide fiber of cut-out is high, and poor for the dispersive property of crude rubber, is difficult to like this come the molding driving belt with the crude rubber that wherein mixes longer cut-out aromatic polyamide fibers.Therefore, use the crude rubber that wherein mixes longer cut-out aromatic polyamide fibers can not obtain the good driving belt of serviceability.
Summary of the invention
The object of the invention is to address the above problem and a kind of line belt take polyester fibre as skeleton is provided, further improve the serviceability of line belt.
The present invention solves the technological scheme that the prior art problem adopts: the line belt take polyester fibre as skeleton, it is characterized in that comprising the belt body with the crude rubber molding, belt body has the top rubber that is formed at the top side, with the bottom rubber that is formed at the bottom side, cord along the longitudinal extension of belt body is embedded between top rubber and the bottom rubber, the adhesive rubber layer is arranged on the top surface and bottom surface of cord in intimate contact, the top surface of top rubber covers with the face fabric, the bottom surface of bottom rubber covers with fabric, be mixed with in top rubber and the bottom rubber along the cut-out aromatic polyamide fibers of a predetermined direction orientation on the described belt body, and be mixed in the described belt body and along the cut-out polyester fibre of described predetermined direction orientation, wherein, described cut-out polyester fibre is longer than described cut-out aromatic polyamide fibers, the length of described cut-out aromatic polyamide fibers is less than 5mm, the length of described cut-out polyester fibre is greater than 5mm, less than 10mm, the rubber composition of described crude rubber is ethylene propylene copolymer, propylene diene hydrocarbon terpolymer, nitrile butadiene rubber, a kind of among hydrogenated nitrile-butadiene rubber and the neoprene.
As further improving and replenishing technique scheme, the present invention adopts following technical measures: with respect to 100 parts rubber composition in the crude rubber, described cut-out aromatic polyamide fibers and the described cut-out polyester fibre of gross weight 10-35 part is mixed in the described crude rubber.
Described cut-out polyester fibre be polyethylene isophthalate fiber, the cut-out of the PET fiber that cuts off, cut-out the poly fiber, derive from the cut staple of beta-propiolactone ring-opening polymerization polymer, a kind of with in the cut staple of the polymer that derives from terephthalic acid diformazan enzyme and 1,4-CHDM polymerization; Described cut-out aromatic polyamide fibers be the contraposition aromatic polyamide fibers that cuts off and cut-out between a kind of in the aromatic polyamide fibers of position.
The poly-enzyme fiber of described cut-out aromatic polyamide fibers and described cut-out is along the width direction orientation of described belt body.
The beneficial effect that the present invention has: will cut off aromatic polyamide fibers and gather the enzyme fiber than the cut-out of cutting off aromatic polyamide fibers length being mixed in the crude rubber.In this case, the poly-enzyme fiber of nearly all cut-out advances and cuts off aromatic polyamide fibers along rolling the direction orientation, improves the serviceability of line belt.
