Abstract
The invention relates to a flame retardant for flame-retardant power cables. The flame retardant is 4-(1-acryloyl piperidine-3-group)-2-(1-methyl-1H-pyrazole-4-group)-1H-indole-7-formamide. The flame-retardant power cables have good flame-retardant characteristics and are quite suitable for being used in the field of factories and mines, projects and ports.
Description
Technical field
The present invention relates to power cable field, specifically, the present invention relates to a kind of fire-retardant electric power
Cable fire retardant.
Background technology
Along with economic develops rapidly, electric wire all obtains extensively in industry-by-industry, field
General application.While electric wire consumption constantly increases, the accident of electrical fire increases the most therewith
Adding, the security of electric wire product, the feature of environmental protection, service life there has also been higher requirement,
The fire-retardant problem of electric wire gradually causes the attention of countries in the world.As far back as the seventies, domestic
In succession develop flame retardant cable outward, though these flame retardant cables have certain flame retardant effect, but also deposit
In many defects, as resistance to elevated temperatures is the strongest, it is impossible at high temperature operation；Resistance to ag(e)ing is inadequate,
Service life is short, pole fire hazardous；When fire occurs, the electric wire of burning can produce
Toxic gas and smog, this not only can affect disaster relief work, lives and properties also can cause "
Secondary disaster ".In view of many industrial departments and the municipal administration civilian installation pair such as subway, skyscraper
The requirement of the safety and reliability of cable is more and more higher, the resistance to height that an urgent demand exploitation is of new generation
Temperature flame retardant cable.
Summary of the invention
It is an object of the invention to provide a kind of flame-proof power cable fire retardant.
In order to realize the purpose of the present invention, the present invention provides a kind of flame-proof power cable fire retardant,
It is characterized in that, described fire retardant is 4-(1-acryloylpiperidine-3-base)-2-(1-methyl isophthalic acid H-pyrrole
Azoles-4-base)-1H-indoles-7-formamide.
The present invention also provides for 4-(1-acryloylpiperidine-3-base)-2-(1-methyl isophthalic acid H-pyrazoles-4-
Base)-1H-indoles-7-formamide is as the purposes in fire retardant.
Preferably, described fire retardant can make powder.
Flame-proof power cable of the present invention has good flame-retarding characteristic, is fully compatible in factory
The fields such as ore deposit, engineering, harbour use.
Detailed description of the invention
Below by way of the description of detailed description of the invention, the invention will be further described, but this is not
Being limitation of the present invention, those skilled in the art, according to the basic thought of the present invention, can do
Go out various amendment or improvement, but without departing from the basic thought of the present invention, all in the present invention
Within the scope of.
The preparation of the flame-proof power cable of embodiment 1 present invention
Weigh PVC 80 kilograms, 3 kilograms of plasticizer, 5 kilograms of antioxidant, fire retardant 8 kilograms,
Vulcanizing agent 10 kilograms, filler 7 kilograms, coupling agent 5 kilograms, described plasticizer is O-phthalic
Dioctyl phthalate.Described antioxidant is the double lauryl of thio-2 acid.Described fire retardant is 4-(1-
Acryloylpiperidine-3-base)-2-(1-methyl isophthalic acid H-pyrazoles-4-base)-1H-indoles-7-formamide.Institute
Stating vulcanizing agent is N, a N '-penylene BMI.Described filler is carbon black.Described idol
Connection agent is γ-chloropropyl-trimethoxy silane.
PVC is placed in drying box and is dried 2 hours, seal and take out after being cooled to room temperature, add
Enter in the high speed Banbury mixer being preheated to 110 DEG C, stir mixing 5 points with the speed of 600 revs/min
Clock, adds carbon black and 4-(1-acryloylpiperidine-3-base)-2-(1-methyl isophthalic acid H-pyrazoles-4-base)-1H-
Indoles-7-formamide, 800 revs/min are stirred 10 minutes, then put in cold mixer by material, and 200
Rev/min stirring until material is cooled to room temperature；Material is delivered in two-roll mill, add neighbour
Dioctyl phthalate, thio-2 acid double lauryl, N, a N '-penylene BMI
With γ-chloropropyl-trimethoxy silane preliminary roller 115 DEG C, back roller 125 DEG C, mill 10 minutes, go out
Put into after material in the mould of vulcanizing press and be pressed into sheet material, the temperature of vulcanizing press is set
It is 160 DEG C, boosts to 5MPa, suspend 2 venting therebetween, suppress 15 minutes under 5MPa, with
The rear cooling plasticizing demoulding in 10 minutes, sample preparation after cooling.
The preparation of the flame-proof power cable of embodiment 2 present invention
Preparing according to the technique identical with embodiment 1, difference is not use 4-(1-propylene
Acylpiperidine-3-base)-2-(1-methyl isophthalic acid H-pyrazoles-4-base)-1H-indoles-7-formamide.
Experimental example
Vertical combustion performance is tested
Vertical combustion experiment is a kind of main method of evaluation material combustion grade, with actual conditions
Relatively being consistent, and simulation is relatively good, wherein flame retardant rating is divided into FV-0, FV-1, FV-2
Three Estate, the fire-retardant rank of FV-0 is the highest, and fire resistance is optimum.
The material sample prepared in embodiment 1 and 2 is cut into according to GB/T2918-1996
13mm × 120mm × 3mm batten, according to GB2918, by the sample of 13mm × 120mm × 3mm
Bar, temperature 25 DEG C, regulates 48h, respectively at vertical combustion instrument under the conditions of relative humidity 50%
On do fire resistance test.The material sample prepared in embodiment 1 and 2 equal retest 5 respectively
Secondary.Result is as follows: in embodiment 1, the flame retardant rating of the sample of preparation is FV-0, and embodiment 2
The flame retardant rating of the sample of middle preparation is FV-1, it can be seen that, use the fire-retardant effect after fire retardant
Fruit is remarkably reinforced.
