Abstract
The invention discloses a PVC sheath with CPE and MBS resistance. The PVC sheath is prepared from 60-70% of PVC resin, 15-40% of a high-efficiency modifier, 5-10% of a flame retardant, 2-5% of packing, 2-5% of an internal/external lubricant, 2-5% of an impact resisting agent and 2-5% of a stabilizing agent. The PVC sheath disclosed by the invention has good high temperature resistance and anti-aging property, is applicable to high temperature caused by overload short circuit generated when an electric cable is used, is high in insulating strength and volume electrical resistivity, good in flexibility, high in compressive strength, and differential settlement resistant, does not need to be coated by placing concrete in a construction field, and is small in inner wall surface friction coefficient, beneficial to use and long in service life.
Description
Technical field
The present invention relates to cable shoe, be specifically related to a kind of PVC sheath of CPE, MBS resistance.
Background technology
Current engineering cable shoe is take polyvinyl chloride (PVC) RESINS as major ingredient, water-ground limestone is mixed for filler and the small powder such as chlorinatedpolyethylene, paraffin, and possess certain corrosion-resistant, high temperature resistant, fire-retardant, insulate the wear-resisting characteristic such as lightweight, pollution-free.But it is poor that its weak point is ultimate compression strength, require gap in addition with construction application, its flame retardant properties is also not ideal enough; Its vicat softening temperature is hovered at about 90 DEG C in addition, and inner and outer pipes wall friction coefficient is large, adds the difficulty of construction usage.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to the PVC sheath of CPE, MBS resistance being to provide a kind of excellent property.
To achieve these goals, the present invention realizes by the following technical solutions: its formula by the polyvinyl chloride resin of 60%-70%, high effective and modified dose of 15%-40%, the fire retardant of 5%-10%, the increasing material of 2%-5%, lubrication prescription, the anti-impact agent of 2%-5% and the stablizer of 2%-5% inside and outside 2%-5%.
As preferably, described high effective and modified dose is soft strong agent.
As preferably, described anti-impact agent is CPE or MBS.
As preferably, other auxiliary agents described are whipping agent and static inhibitor.
As preferably, described stablizer is one package stabilizer.
As preferably, described filler is calcium carbonate.
As preferably, described inside and outside lubrication prescription is stearic acid.
As preferably, described stablizer is calcium-zinc composite stabilizing agent.
Product of the present invention has high temperature resistant and ageing resistance is good, and can adapt to the high temperature that power cable use procedure produces because of overload short circuit, material has high insulation resistance and volume specific resistance; Flexible and ultimate compression strength is large, anti-non-uniform settling, need not pouring concrete be encapsulated at the construction field (site); Inner wall surface coefficient of friction is little, is beneficial to use, and product life is long.
The present invention is described in detail below in conjunction with embodiment.
embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
This embodiment is by the following technical solutions: the PVC sheath of CPE, MBS resistance, its formula by the polyvinyl chloride resin of 60%-70%, high effective and modified dose of 15%-40%, the fire retardant of 5%-10%, the increasing material of 2%-5%, lubrication prescription, the anti-impact agent of 2%-5% and the stablizer of 2%-5% inside and outside 2%-5%.
It should be noted that described high effective and modified dose is soft strong agent.
It should be noted that described anti-impact agent is CPE or MBS.
It should be noted that other auxiliary agents described are whipping agent and static inhibitor.
It should be noted that described stablizer is one package stabilizer.
It should be noted that described filler is calcium carbonate.
It should be noted that described inside and outside lubrication prescription is stearic acid.
It should be noted that described stablizer is calcium-zinc composite stabilizing agent.
Product of the present invention has high temperature resistant and ageing resistance is good, and can adapt to the high temperature that power cable use procedure produces because of overload short circuit, material has high insulation resistance and volume specific resistance; Flexible and ultimate compression strength is large, anti-non-uniform settling, need not pouring concrete be encapsulated at the construction field (site); Inner wall surface coefficient of friction is little, is beneficial to use, and product life is long.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
