Description

A kind of antifouling work supertension insulant
Technical field
A kind of the present invention relates to CABLE MATERIALS technical field, more particularly to antifouling work supertension insulant.
Background technology
Low Density Polyethylene due to viscosity in process is relatively low and have in drawing process high fondant-strength with When also have both not available for the conventional materials such as extremely strong resistance to chemical attack, acid and alkali-resistance, oil resistant, the nontoxic, long service life of light weight Advantage, therefore its range of application is throughout development and the various aspects of people's lives of national economy, for example electric wire, defeated Send pipeline, automotive trim and construction material etc..But the oxygen index value of polyethylene is low, inflammable, and under field conditions (factors), with regard to energy Deflagrate, thermal discharge are big, worse with molten drop behavior, may cause spot fire, and also can during decomposes A large amount of toxic and harmfuls are volatilized, people life property safety is threatened, and resistance to water is also poor, cause its application to be received To restriction.So needing fire-retardant to which, and water resistance is improved, reduce the probability that fire hazard occurs, therefore which is carried out fire-retardant Process is particularly important.
《The preparation and its performance study of expansible fire retardant low-density polyethylene》One literary author is poly- for current low-density There is the technical barrier of poor water resistance during vinyl material halogen-free flameproof, using macromolecular carbon forming technology and encapsulation skill The mode that art combines, development of new is water-fast halogen-free expanded flame-retardant LDPE Composite, wherein carbon forming agent select three The APP of piperazine analog derivative CFA, dehydrant and foaming agent from Silica hydrogel parcel, this new Low Density Polyethylene material Material not only has higher thermal stability and fire resistance, while also overcoming the difficulty of poor water resistance.Although present invention solution Low density polyethylene fire retardant of having determined is poor, the problem of poor water resistance, improves polyethylene safety coefficient in use, but Be Low Density Polyethylene however for high pressure field direct current cables in running, the low conductivity characteristic of polyethylene is caused The space charge of accumulated inside is difficult to spread, and causes the Severe distortion of local field strength, especially when there is temperature in oepration at full load During Gradient Effect, this phenomenon is even more serious, when surface of insulating layer local field strength reaches certain value, will cause shelf depreciation, The insulation ag(e)ing phenomenon such as resinification, substantially reduces the service life of cable, to this improve polyethylene anti-flaming, water resistance same When, improve its insulating properties and particularly seem urgent.

The present invention is achieved by the following technical solutions：
A kind of antifouling work supertension insulant, is made up of the raw material of following weight portion：Low Density Polyethylene 40-45, poly- Ammonium phosphate 11-13, OP100.3-0.5, tetraethyl orthosilicate 12-15, polyarylsulfone (PAS) powder 5.5-7, Colophonium 4-5, protein cellulose 13- 15th, BIPB cross-linking agent 0.4-0.6, styrene 17-19, HMPA 1.4-1.6, silicon powder 2.5-4, field spar 7-9, Limestone 10-14, polydimethylsiloxane 0.4-0.6, acrylic acid 3.6-4, appropriate dehydrated alcohol, appropriate deionized water.
A kind of antifouling work supertension insulant, is made up of step in detail below：
（1）By deionized water and dehydrated alcohol in mass ratio 1:2 are added in flask, warming while stirring to 40 DEG C, add poly- phosphorus Sour ammonium stirring dissolves which, dissolves and is slowly added to OP10 in above-mentioned solution backward, and with ammonia regulation system pH value 9-10, continues Stirring 10-20min, then tetraethyl orthosilicate is added in above-mentioned solution, after completion of dropping, continue reaction 2-3h, finally cool down To room temperature, filter, dry, wash and be put into dry product in baking oven；
（2）BIPB cross-linking agent, styrene are placed in high-speed mixer and are mixed, add HMPA and albumen Cellulose continues to stir, and rosin heating is added thereto to after melting, and continues stirring 20-35min, is cooled to room temperature standby With；
（3）Silicon powder, field spar are added in ball mill and wear into fine powder, then mixed with polydimethylsiloxane, acrylic acid Mixture is obtained, the dimethylformamide dissolving that polyarylsulfone (PAS) powder is measured with 4-6 times is added to said mixture in polyarylsulfone (PAS) solution Go, heated and stirred is subsequently placed in vacuum drying oven and is dried to glutinous thick liquid is formed；
（4）By step（3）The product of preparation adds the 3-4 times of dimethylbenzene for measuring part, ultrasonic disperse 20-30min to add limestone Continue ultrasound uniform, scattered suspension under mechanical agitation is heated to seething with excitement, add 10% Low Density Polyethylene Continue stirring 3h, be then added to dehydrated alcohol and deionized water volume ratio 1:In 1 solution, filter, dry；
（5）By step（1）And step（2）The product of preparation dries 5-6h in vacuum drying oven at 80 DEG C, after taking-up and step （4）The product of preparation, remaining leftover materials temperature in double-roll rolling mill is 150 DEG C, and rotating speed is 60 revs/min of melt blending 10- 15min, compressing after in 80 DEG C of vacuum drying close annealing, short-circuit 24h, after room temperature is at the uniform velocity down to 5 DEG C/min.
It is an advantage of the invention that：The present invention improves dividing in polyethylene using styrene, Colophonium parcel protein cellulose Scattered property, and play a part of charcoal source wherein, intumescent carbon-coating can be generated together with ammonium polyphosphate modifying, be attached to material Material surface, prevents heat and the contact for having prevented with oxygen, and reduce imflammable gas again diffuses speed, improves material The fire resistance of material, produces intermolecular force between the mixed-powder and Low Density Polyethylene of preparation, and in vacuum drying oven The residual stress produced in middle elimination pressing process, makes the crystal habit of material more perfect, eliminates in Sample Preparation Procedure The space charge that portion produces, improves breakdown strength, plays good insulating effect, and also enhance CABLE MATERIALS antifouling, The performances such as insulation, cable material toughness prepared by the present invention is high, processability is good, the fire-retardant, antifouling of material, insulating properties Good, equipment investment is few, and production process is simple, and properties of product are stable, long service life.
