Specific embodiment
Below in conjunction with the embodiment of the present invention, technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Embodiment one: the present invention provides a kind of technical solution: a kind of ETFE coloring color masterbatch, the technological process of production are as follows:
Weighing: in the case where temperature is maintained at room temperature, clean environment, vector resin and various additives are passed through into different vessels respectively
It is placed, carries out component: 1.5 parts of colorant, 30 parts of vector resin, 1.5 parts of dispersing agent, coupling agent according to following mass fraction
2 parts, 5 parts of plastic plasticizer, 2 parts of antistatic agent, 2 parts of heat stabilizer, 5 parts of ceramic, 4 parts of antioxidant, the load weighed
Body resin is each separated in different containers from various additives.
Stirring: vector resin is put into high mixer, heating adds vector resin while high mixer stirs vector resin
Heat is melted, and colorant, which is put into high mixer, after vector resin loses graininess mixes colorant with vector resin, to
After toner is sufficiently mixed vector resin, by rest additive according to dispersing agent, coupling agent, plastic plasticizer, antistatic agent, heat
Stabilizer, ceramic, antioxidant sequence be put into high mixer, and before waiting certain time to make before being put into additive every time
One additive is sufficiently mixed with vector resin.
Tie rod: the temperature of extruder being set, is switched on after held for some time, by high mixer heating stirring it is abundant after
The mixture of the feed inlet of vector resin and the mixture of various additives injection extruder, vector resin and various additives exists
Material strip is squeezed into extruder.
Qie La: material strip is cut into graininess to Dutch machine drawing feed inlet, by pelleter by material strip, the color masterbatch that pelletizing is completed
Grain is quantitatively packed.
Masterbatch made of the present embodiment and electric wire made of ETFE adapt to that usage amount is big, weather is damp and hot and electric wire is exposed to
Carried out when the external environment of crowd's life using, the deal ratio of colorant and vector resin is 1:15, make Masterbatch contain compared with
More coloring agent components makes the more bright-coloured beauty of manufactured electric wire color, the deal of heat stabilizer, ceramic particle and vector resin
Ratio is 1:5:30, replaces heat stabilizer using a large amount of ceramics, ceramic price is lower than heat stabilizer, makes Masterbatch
Cost of manufacture is lower, allows and reduces cost payout when a large amount of uses, heat stabilizer provides heat-resisting to a certain degree for Masterbatch
Etc. performances reinforcement, the ratio of antioxidant, antistatic agent and vector resin is 2:1:15, because the electric wire of the present embodiment need with
Air contacts and increases stronger antistatic property with substances friction, addition antioxidant, antistatic agents such as dusts for Masterbatch
And antioxygenic property, environment is exposed on the external because the electric wire of the present embodiment is naked, mould is difficult to grow and spread on its surface, so not
Fungicidal properties is set.
Titanium white, chrome yellow, barba hispanica, cadmium red, cadmium yellow, lithopone, carbon black, iron oxide red and iron oxide in colorant inorganic pigment
One of Huang, inorganic pigment have the advantages that cheap and heat-resisting, sun-proof, weather-proof and solvent resistance is good, are suitble to production electricity
Line uses.
Vector resin uses fluoropolymer resin, vector resin using resin identical with EFTE as carrier, with
The compatibility of ETFE is best.
Dispersing agent uses low-density polyethylene wax, and dispersing agent, which is added in master batch, dual influence, it is strengthened to face
The wetting and infiltration of dough aggressiveness, improve the compatibility of pigment and system, and reduce system viscosity, are conducive to point of pigment
It dissipates.But system viscosity reduces the shearing force reduction that can excessively make to be transmitted to pigment, so that the dispersion train to pigment carrys out unfavorable shadow
It rings, and low-density polyethylene wax can accelerate paint flow fortune property, improve the effect of dispersion, make pigment being wrapped by more evenly.
Coupling agent is used in various kinds of resin base or rubber composite material using coordination figure titanate coupling agent, such coupling agent
There is good coupling effect in system, it overcomes general titanate coupling agent lacking used in polymer matrix composites system
Point.
Plastic plasticizer enables dioctyl phthalate using electrical grade DOP(), motor grade DOP is complete with general purpose grade DOP's
Outside portion's performance, also there is good electrical insulation capability.
For antistatic agent using one of macromolecule permanent antistatic agent, macromolecule permanent antistatic agent is to reduce
Material volume resistivity reaches antistatic effect, does not completely depend on water absorbent surface, so being influenced to compare by the humidity of environment
It is smaller.
Heat stabilizer uses organic tin stabilizer, and stabilizer can be prevented effectively, reduce the even basic drop for stopping material
Solution, and sulphur-containing stabilizer is all outstanding in terms of all stabilities.
For ceramic using products more than 6000 mesh, ceramic is used as a large amount of substitution heat stabilizers, ceramic master
Wanting composition is Si02 and Al203, and good dispersion, covering power height, whiteness are up to 93 or more, and density is small, light scattering good, refractoriness
Up to 1300 or more.The material composition of alumina silicate makes it have good acid and alkali-resistance, corrosion-resistant and insulation performance and has well
