Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Igelite of the present invention is mainly used in the making of electric automobile charging pile tie cable sheath material, igelite comprises polyvinyl chloride (PVC) RESINS, dioctyl phthalate (DOP), dioctyl sebacate, calcium-zinc composite stabilizing agent, paracril, SEBS rubber, wherein, SEBS rubber is the segmented copolymer being reacted by styrene ethylene butadiene-styrene hydrogenation and make, be take vinylbenzene as end segment, the ethylene-butene copolymer obtained with butadiene hydrogenation is the line style of middle spring block or star-like three embedding multipolymers.
Described igelite, when not increasing liquid plasticizer total amount, adopts SEBS rubber and paracril as extender plasticizer, each composed as follows:
Polyvinyl chloride (PVC) RESINS 100 parts;
Dioctyl phthalate (DOP) 10-30 part;
Dioctyl sebacate 1-20 part;
Calcium-zinc composite stabilizing agent 2-10 part;
Paracril 0-25 part;
SEBS rubber 5-25 part;
Calcium carbonate 0-50 part.
Soft polyvinyl chloride plastic adopts low-molecular-weight liquid plasticizer plasticising to make it have flexibility usually, the softening agent addition of common polyvinyl chloride cable sheath is 50-60 part, require to can't steer clear of at-15 DEG C of temperature last volumes to split, but there is the danger of bending crack at lower temperatures, out of doors, common igelite should not be used for the sheath material of charging pile cable.
Kind and the addition of the flexibility of polyvinyl chloride cable material and the liquid plasticizer added are closely related, usually, along with the addition of liquid plasticizer in polyvinyl chloride cable material improves, the flexibility of material and elongation at break improve, cold tolerance strengthens, but the mechanical property of material and volume resistance decline, oil resistant and rolling resistance ability decline simultaneously, its reason is because the liquid plasticizer volume resistance of small-molecular-weight is low, adopt the polyvinyl chloride cable material Intermolecular Forces of relatively large liquid plasticizer plasticising to decline and affect the mechanical property of material, micromolecular softening agent is easily oily, the media such as water extract and cause polyvinyl chloride cable material brittle hardening until aging, finally, cause reduce the work-ing life of electric wire, safety performance is more difficult to get guarantee.
We find in process of the test, in common polyvinyl chloride cable material formula situation, by adding of SEBS rubber and paracril, and adopt ratio component of the present invention, can when not increasing liquid plasticizer total amount, make the low temperature impact properties of polyvinyl chloride cable material, hardness had obvious improvement, also improve resistance to daylight and the oil resistance of material simultaneously.
SEBS rubber is the segmented copolymer being reacted by styrene ethylene butadiene-styrene hydrogenation and make, and be take vinylbenzene as end segment, the ethylene-butene copolymer obtained with butadiene hydrogenation is the line style of middle spring block or star-like three embedding multipolymers.SEBS rubber is a kind of multiduty novel thermoplastic elastomer.Owing to not containing unsaturated double-bond in SEBS rubber, therefore there is satisfactory stability and ageing resistance.And there is good mechanical property, not only to ozone, ultraviolet, electric arc, there is good tolerance, also there is the lower temperature resistance of good oil resistant, chemicals-resistant corrodibility and excellence.
Due to SEBS rubber molecular chain not containing polarity or reactive group, poor with other high molecular polymer consistency, in order to strengthen the consistency of SEBS rubber and polar polymer, need to carry out grafting to SEBS rubber or add the 3rd ingredient compatibility material.
A kind of synthetic rubber that paracril is obtained by divinyl and acrylonitrile compolymer.In paracril, acrylonitrile content not only affects its oil resistance, low-temperature performance, and directly affects the consistency with polyvinyl chloride (PVC) RESINS, and wherein acrylonitrile content (%) 25 ~ 35 is comparatively suitable.
Utilize the constructional feature of paracril as the compatibility material of SEBS rubber and polyvinyl chloride (PVC) RESINS in the present invention, improve the interaction force between SEBS/PVC phase interface, make disperse phase less and evenly in basal granule distribution, become a stable submicroscopic dispersion state.
Adopt the electric automobile charging pile tie cable sheath that igelite of the present invention is made, its product Specifeca tion speeification is as follows:
1. low-temperature performance: at-40 DEG C, cord wrap does not ftracture;
2. immersion oil resistance to 90 DEG C of mineral oil performances after 24 hours: tensile strength velocity of variation >85%, elongation at break velocity of variation >80%;
