Description

Cable material of a kind of corrosion-resistant resistance to worm ant and preparation method thereof
Technical field
The present invention relates to technical field of polymer materials, particularly relate to cable material of a kind of corrosion-resistant resistance to worm ant and preparation method thereof.
Background technology
Polyvinyl chloride (PVC) is a kind of purposes general-purpose plastics widely, different according to the amount of adding softening agent, hard, semi-rigid and flexible article can be made, modification can also be carried out with other polymer blendings, make goods that are of a great variety, different properties, consumption is very large, is one of large general-purpose plastics in the world five.The demand of polyvinyl chloride resin and polyethylene, polypropylene rank front three in the world, and have risen to first at its consumption of China.Polyvinyl chloride itself is also inherent flame retardant material, and its oxygen index is very high, and flame retardant effect is fine, but pure PVC is rigid chain segment, just start to decompose more than 90 DEG C, processing just must add softening agent, softening agent is all inflammable substance, so flexible PVC must add fire retardant just have flame retardant effect.And polyvinyl chloride can produce hydrogen chloride gas when burning, and have very large toxicity and corrodibility, and dense smoke is more.Along with the raising of environmental requirement, the adjacent benzene class such as DOP softening agent is prohibited, and will play every advantage of poly-ethylene cable material thus further.
Polyethylene (PE) is one of maximum general-purpose plastics of current production rate, there is chemical resistance, light weight, electrical insulating property, nontoxic, easy processing, lower-price characteristic, be widely used in the industries such as electrical equipment, chemical industry, packaging, food, traffic, building.But the oxygen index of PE only has 17.5%, belongs to inflammable material, therefore need to carry out flame-retardant modified process to expand its range of application to it.Also have dielectric characteristics in order to improve poly-ethylene cable material, as space charge gather, volume specific resistance and disruptive strength etc., current high voltage direct current cable generally adopts traditional method to carry out modified poly ethylene Insulation Material.Wherein blending technology improves polyethylene dielectric properties to use a kind of maximum methods, but the blended micro interface that can form two phase structure of different components, even occur to material surface infiltration and separation phenomenon, affect other dielectric properties of blend, dielectric strength may be caused to reduce as blended.Therefore, the best way is that the component that use two kinds of chemical structures are similar, consistency is good is blended to carry out, thus eliminates the detrimentally affect of the micro interface of bi-material.
On market, common low-smoke halogen-free cable does not have insect-pest function simultaneously, and the cable having insect-pest to corrode mostly is polyvinyl chloride insulation and sheath.Though the anti-ant effect that polyvinyl chloride anti-termite cable tool is certain, but material has certain pollution to environment, and does not have high flame retardant.

(2) nano-aluminum hydroxide and metallocene PE to be placed on respectively in 80 DEG C of Constant Temp. Ovens thermal treatment 6 hours stand-by; By dried nano-aluminum hydroxide ultrasonic disperse in hexanaphthene, form suspension, then add γ-aminopropyl triethoxysilane, suspension was poured in vessel after 20 minutes by ultrasonic disperse, put into baking oven, dry 24 hours at the temperature of 60 DEG C, obtain the nano powder of surface modification; The nano powder of dried metallocene PE and surface modification puts into mixer, and with the temperature batch mixing 30 minutes of 140 DEG C, then extruding pelletization in twin screw extruder, makes resistance and wear modified master;
(3) glass fibre is put into pulverizer to pulverize, cross 200 mesh sieves to mix with diatomite, then add clarification liming, permethrin, garlic powder, put into homogenizer together, pour out after stirring 30 minutes with the speed of 1200 revs/min and obtain desinsection auxiliary agent;
(4) natural rubber is put into Banbury mixer, add coumarone with the temperature banburying of 150-160 DEG C after 10 minutes, continue banburying 5 minutes, be cooled to 100 DEG C, start discharge, after cooling, obtain mixture;
(5) flame-retardant master batch, resistance are worn modified master, desinsection auxiliary agent, mixture, remaining high density polyethylene(HDPE) and all the other remaining components and put into high-speed mixer, it is 160 DEG C in temperature, 15 minutes are mixed under the speed of 500 revs/min, blanking in 10 minutes is mixed again with the speed of 2000 revs/min, then twin screw extruder extruding pelletization is put into, finally by pellet in 80 DEG C of baking ovens dry 24 hours and get final product.
Advantage of the present invention is: the present invention is by the modification of recipe optimization, add the composition such as nano-aluminum hydroxide and metallocene PE, the introducing of these compositions significantly reduces injection and the gathering of space charge, improve space charge characteristic, improve DC breakdown strength of electric field, simultaneously due to containing a small amount of metallocene PE, improve tensile strength and the over-all properties of CABLE MATERIALS.Add decabromodiphenyl oxide and antimonous oxide, synergy, decreases the growing amount of inflammable gas, changes the resolution model of polymkeric substance, the thermostability of material is improved.Simultaneous reactions decomposites SbBr 3, the long period can rest on combustion zone, there is dilution and buffer action, improve flame retardant properties further.
