Description
Technical field
The present invention relates to cable insulation jacket technical field, more particularly, to a kind of moistureproof PVC insulating sheaths.
Background technology
In the prior art, cable industry is usually using PVC insulating sheaths as insulating protection, and PVC insulating sheaths use
As raw material, but due to the self shortcoming of polyvinyl chloride resin, PVC cable material is easy to make moist PVC injection molding materials, uses the electricity to make moist
The dim coarse tarnish of wire surface that cable material is made, all there are many honeycomb-like pores, drops significantly in wire surface and cross section
The low mechanical performance and insulating properties of electric wire., it is necessary to carry out drying and processing before using the CABLE MATERIALS made moist, one is added
Procedure, speed of production is not only have impact on, also waste of manpower and the energy.Conventional PVC Insulation Materials are made usually using ordinary calcium carbonate
For filling, the insulated cable particle surface that ordinary calcium carbonate is made appears to be uneven with microscope and has Pinhole-shaped
Gap, these gaps are easy to suction steam, have led to making moist.
The content of the invention
To solve the above problems, the invention provides one kind to have moisture-resistant moisture barrier properties, and it is smooth with product surface
The PVC insulating sheaths of fine and smooth, the pliability characteristic such as preferably.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of moistureproof PVC insulating sheaths, it is molded by moistureproof PVC injection molding materials and is made；
Moistureproof PVC injection molding materials are made by the raw material of following parts by weight, 80~90 parts of polyvinyl chloride resin, and 20~40 parts of PE resins are inorganic to fill out
120~140 parts of material, 25~30 parts of compounded rubber, 2~3 parts of mobility modifying agent, 10~12 parts of plasticizer, 5~7 parts of lubricant,
6~8 parts of heat stabilizer.
The appropriate rubber of addition improves its pliability to reduce the hardness of injection molding material in the present invention；Mobility modifying agent
The processability of injection molding material can be improved so that more effective can must prepare rubber etc. outside cable；Film forming agent to be molded
Material surface can form one layer of film that can play waterproof action, also cause the outside of obtained cable rubber etc. after injection
One layer of film with waterproof action is formed, improves its humidity resistance；PE resins have more preferable processing characteristics compared to PVC,
There is preferable chemical stability simultaneously, be properly added the processing characteristics that can improve polyvinyl chloride resin after PE resins, improve simultaneously
The cryogenic property of polyvinyl chloride resin.
Preferably, inorganic filler is modified muscovite.
Preferably, modified muscovite is made by following methods：
The PVP of the absolute ethyl alcohol of 0.3~0.6 times of muscovite and muscovite weight, 0.1~0.2 times of muscovite weight is mixed simultaneously
Together it is added to high-speed shearing machine to handle 0.5~1.5 hour, and stripping is made after 550~600 DEG C of calcinings cooling in 0.5~1 hour
From muscovite；Muscovite will be peeled off and mix supersound process 1~2 with peeling off the titanate coupling agent of 0.5~1.0 times of muscovite weight
Hour, modified muscovite is made.
Muscovite is a kind of inorganic silicate mineral of lamellar.It is an object of the invention to provide a kind of moistureproof injection molding material,
Using the mineral of lamellar as filler, the stacking of filler can be made closer so that conventional particulate filler is not present between filler
Between the existing gap for being difficult to fill up, while injection molding material surface can also be made to form a close protective layer, prevent PVC trees
The fat moisture absorption.But the muscovite as raw material generally makes the stacking form of multilayer, is not complete individual layer or laminate structure,
Therefore need to carry out delamination processing to muscovite before addition.Delamination processing in the present invention, using high-speed shearing machine plus poly-
The method of compound intercalation is realized, is crushed muscovite as far as possible with high-speed shearing machine, and realizes that delamination is handled to a certain extent, is made
Obtain muscovite and become relatively thin lamella, while high speed shear, a certain amount of high polymer PVA is added, by cutting at a high speed
The effect of cutting so that PVA constantly into muscovite interlayer structure in, high speed shear for a period of time after, when in interlayer structure
When PVA contents are enough, then by after processing muscovite calcine, remove the high polymer PVA of interlayer, and realize muscovite synusia stripping
From.In addition to improving filler and PVC compatibility, filler surface is modified.
Preferably, compounded rubber includes following components in percentage by weight, 35~40wt% of nitrile rubber, EPDM
10~20wt% of rubber, silicon rubber 10~15%, surplus are neoprene.
Nitrile rubber can improve rubber and PVC with good water resistance, air-tightness and excellent adhesive property
Binding ability between resin, while assign PVC injection molding materials preferable water resistance；Ethylene propylene diene rubber has well low temperature resistant
Performance, the cryogenic property of injection molding material can be improved after addition；Neoprene has a good physical and mechanical properties, oil resistant, heat-resisting, resistance to
Combustion, resistance to daylight, resistance to ozone, acid and alkali-resistance, chemical-resistant reagent, the stability of injection molding material can be improved；Silicon rubber has preferably resistance to
Performance is waited, there is wider array of use environment.The addition of rubber simultaneously, moreover it is possible to assign injection molding material more preferable flexibility, make it not stiff
Firmly, more use environments can be applied to.
Preferably, plasticizer is by weight 1 by DOTP and dioctyl phthalate：0.5~
0.8 composition.
Preferably, lubricant is one kind in stearic acid or barium stearate.
Preferably, mobility modifying agent is by weight 1 by talcum powder, graphite and EMI resins：1：0.5~0.8 group
Into.
Preferably, film forming agent is oxidic polyethylene alcohol and Tissuemat E by weight 1：0.6~0.8 composition.
Oxidic polyethylene alcohol and Tissuemat E can be effectively distributed in the surface of PVC Insulation Materials, play a part of protecting film,
So as to substantially increase the humidity resistance of PVC Insulation Materials, extend the shelf-life of PVC Insulation Materials.
Therefore, the invention has the advantages that：Moistureproof PVC insulating sheaths in the present invention have moisture-resistant moistureproof special
Property, and with product surface smooth fine and smooth, the pliability characteristic such as preferably.
