Description
Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of Colophonium anticracking waterproof high performance cable material and preparation method thereof.
Background technology
Polrvinyl chloride (PVC) is a kind of purposes general-purpose plastics widely, different according to the amount adding plasticizer, hard, semi-rigid and flexible article can be made, can also be blended with other polymer and be modified, make of a great variety, the goods of different properties, consumption is very big, is one of big general-purpose plastics in the world five.Demand and polyethylene, the polypropylene of polyvinyl chloride resin ranks front three in the world, and has risen to first at its consumption figure of China.Polrvinyl chloride itself is also inherent flame retardant material, and its oxygen index (OI) is the highest, and flame retardant effect is fine, but pure PVC is rigid chain segment, beginning to decompose more than 90 DEG C, processing is necessary for adding plasticizer, plasticizer is all combustibles, so flexible PVC must add fire retardant just flame retardant effect.And polrvinyl chloride can produce hydrogen chloride gas when burning, has the biggest toxicity and corrosivity, and dense smoke is more.Along with the raising of environmental requirement, the adjacent benzene class plasticizer such as DOP has been prohibited, and will play every advantage of poly-ethylene cable material thus further.
Polyethylene (PE) is one of general-purpose plastics of current production rate maximum, there is chemical resistance, light weight, electrical insulating property, processing nontoxic, easy, lower-price characteristic, be widely used in the industries such as electrical equipment, chemical industry, packaging, food, traffic, building.But the oxygen index (OI) of PE only has 17.5%, belongs to combustible material, it is therefore desirable to it is carried out flame-retardant modified process to expand its range of application.Also have to improve the dielectric property of poly-ethylene cable material, as space charge gather, specific insulation and breakdown strength etc., current high voltage direct current cable typically uses traditional method to carry out modified poly ethylene Insulation Material.Wherein blending technology is to improve polyethylene dielectric properties to use a kind of most methods, but the blended micro interface that can form two phase structure of different component, even occur to material surface infiltration and segregation phenomenon, affect other dielectric properties of blend, may result in dielectric strength reduction as being blended.Therefore, the best way is to use two kinds of components that chemical constitution is similar, the compatibility is good to be blended, thus eliminates the harmful effect of the micro interface of bi-material.
Colophonium is a kind of waterproof and dampproof and antiseptical organic gel gel material, the present invention intends by a series of process modification, Colophonium is added in the preparation of CABLE MATERIALS, it is possible to form the strongest interfacial interaction with major ingredient, the intensity of CABLE MATERIALS, wear-resisting and water resistance can be improved.
