Description
Technical field
The present invention relates to be used to make CABLE MATERIALS technical field, more particularly to a kind of fire-resistant cable material and preparation method thereof.
Background technology
Polyvinyl chloride is a kind of excellent wire cable insulating protective cover material, and light weight is translucent, glossy, is difficult by acid and alkali corrosion, there is preferable mechanical performance, there is excellent dielectric properties, and cheap, therefore in wires and cables industry always in occupation of important share.Belong to soft PVC yet with the polyvinyl chloride that wires and cables industry is used, the degree of polymerization can not be too high, and because itself is harder, soft is changed to it in order to adapt to electric wire demand needs, simultaneously in order to meet the performances such as heat-resisting, low temperature resistant, resistance to migration and meet processing, also a certain amount of plasticizer must be added, causes it to meet wear-resisting and oil resistant requirement, therefore the use of the industry such as automobile mechanical mineral products of and oil resistant wear-resisting in demand is constantly subjected to very big limitation.
It is all blended rubber class or ethlyene dichloride class that simultaneously traditional wear-resistance and oil-resistance is modified, forms polyvinyl chloride alloy.Although the significant alloy of effect can be obtained, processing is more difficult, therefore the blend method of its alloy is also problem demanding prompt solution.
The content of the invention
The purpose of the embodiment of the present invention first is to provide a kind of fire-resistant cable material, using the electric wire that the technical scheme makes, can play the fire-retardant effect of wear-resistance and oil-resistance.
The purpose of the embodiment of the present invention second is to provide a kind of preparation method of fire-resistant cable material, using the electric wire that the technical scheme makes, can play the fire-retardant effect of wear-resistance and oil-resistance.
In order to realize foregoing invention purpose, complete skill scheme of the invention is：
A kind of fire-resistant cable material, its formula is：
100 parts of a, polyvinyl chloride；
60 parts of b, trioctyl trimellitate (TOTM)；
C, 5 parts of barium cadmium zinc composite stabilizer；
40 parts of d, TCEP；
10 parts of e, nitrile rubber
0.6 part of f, stearic acid；
1 part of g, color masterbatch.
A kind of method for preparing above-mentioned CABLE MATERIALS, its step is as follows：
101st, material a is added in high-speed mixer, adds material c, high-speed mixer low-speed running mixes 1 minute；
102nd, add the half component of material b, after high-speed mixer is transferred to the mixing 5 minutes of running at high speed by low speed, add the material b of remaining second half component, high-speed mixer to be transferred to mixed at high speed to 90 DEG C by low speed；
103rd, while adding material d, f and g, mixed at high speed to shutdown after 110-120 DEG C is transferred to after first low speed；
104th, after temperature is cooled to 40-50 DEG C, material e is added, compound is obtained by low speed to mixed at high speed to shutdown after 60 DEG C；
105th, banburying is to 160 DEG C of acquisition clinkers in adding mixture into banbury, then uses small major diameter Single screw extrusion into granular colour masterbatch in clinker, obtains CABLE MATERIALS.
Therefore, using the electric wire that the technical scheme makes, the fire-retardant effect of wear-resistance and oil-resistance can be played.
Specific embodiment
Described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Embodiment 1：
Present embodiment discloses a kind of fire-resistant cable material, its formula is：
100 parts of a, polyvinyl chloride；
60 parts of b, trioctyl trimellitate (TOTM)；
C, 5 parts of barium cadmium zinc composite stabilizer；
40 parts of d, TCEP；
10 parts of e, nitrile rubber
0.6 part of f, stearic acid；
1 part of g, color masterbatch.
A kind of method for preparing above-mentioned CABLE MATERIALS, its step is as follows：
101st, material a is added in high-speed mixer, adds material c, high-speed mixer low-speed running mixes 1 minute；
102nd, add the half component of material b, after high-speed mixer is transferred to the mixing 5 minutes of running at high speed by low speed, add the material b of remaining second half component, high-speed mixer to be transferred to mixed at high speed to 90 DEG C by low speed；
103rd, while adding material d, f and g, mixed at high speed to shutdown after 110-120 DEG C is transferred to after first low speed；
104th, after temperature is cooled to 40-50 DEG C, material e is added, compound is obtained by low speed to mixed at high speed to shutdown after 60 DEG C；
105th, banburying is to 160 DEG C of acquisition clinkers in adding mixture into banbury, then uses small major diameter Single screw extrusion into granular colour masterbatch in clinker, obtains CABLE MATERIALS.
The present embodiment also particularly discloses a kind of mixing procedure principle, is embodied as follows:
1. when dry-mixed, the friction between the friction of rotation lodicule and particle that its heat passes through high intensity mixer or resin particle passes to resin particle to polyvinylchloride resin particle, expands resin particle.
2. the polyvinyl chloride particles adsorption inflated first of the plasticizer in mixed material, mixed display goes out moist and blocking phenomenon.After mixed process is continued for some time, absorption of the resin particle to plasticizer starts rapidly, and plasticizer progressed into and eventually enter between resin particle between its interior molecules space.The absorption process depends on type, quantity and the temperature of plasticizer.
3. after material to be mixed turns into smooth free-flowing by moisture cake shape, remaining powder class material (the wherein not processing aid such as including nitrile rubber NBR, ACM ACR, haloflex CPE) is added.
4. after mixture temperature reaches 110-120 DEG C; shutdown is allowed to cool to 40-50 DEG C; NBR powder and CPE powder are added, mixed at high speed is transferred to after first mixed on low speed, and (this is mainly 1. because NBR, ACR, CPE powder have affinity for plasticizer to 60 DEG C.If the plasticizer of remnants rests on PVC granule surface, it preferentially can be absorbed by NBR from PVC.Plasticizer will expand NBR, and this can cause it to become tacky,
And causing cohesion to be lumpd, NBR, CPE class processing aid main purpose are to promote resin melting, in mixing step and do not need resin melting, and simply dispersion mixing)
Embodiments described above, does not constitute the restriction to the technical scheme protection domain.Any modification, equivalent and improvement made within the spirit and principle of above-mentioned implementation method etc., should be included within the protection domain of the technical scheme.
