Abstract
The invention relates to the field of high polymer materials, especially a silane cross-linked polyethylene cable material, which comprises the following components by mass. Each technical index of the cable material adopting the formula is tested to reach the similar technical levels of foreign countries. With good processability and cable surface quality, the cable material can realize rapid crosslinking. Thus, the production efficiency is improved and the cost is reduced.
Description
Technical field
The present invention designs polymeric material field, especially poly-ethylene cable material, particularly organosilane cross-linked poly-ethylene cable material.
Background technology
Organosilane crosslinked polyethylene is mainly as electric wire coating layer, heat-resisting pipes, flexible pipe and film etc.Also can be used for making high voltage withstanding, the high-frequency heat-resistant insulation materials such as motor, transformer, heat-shrinkable film and sleeve pipe, corrosion-resistant parts, container and the porous plastics etc. of chemical production device also can be used for the high-technology fields such as rocket, guided missile.In recent years, be widely used in corrosion-resistant parts, container and the porous plastics of various tubing (such as hot-water line), chemical production device and fire retardant material etc.Polyethylene after crosslinked all increases significantly on the performances such as resisting environmental stress and cracking at thermotolerance, oil-proofness, creep resistant.Therefore, cross-linking modified vinyon product has become an important directions of polyethylene application and development.But the organosilane crosslinked polyethylene product all need be placed on and just can finish crosslinkedly in vaporium or the 90 ℃ of hot tubs more than 8 hours in the market, and the time is long, and producer also will build sea water bath or vaporium, has greatly increased Enterprise Construction and production cost.
Summary of the invention
The objective of the invention is: a kind of organosilane cross-linked poly-ethylene cable material is provided, and it has higher index not only at thermotolerance, oil-proofness, creep resistant on the performances such as resisting environmental stress and cracking, and can realize Quick cross-linking, enhances productivity, and reduces cost.
A kind of organosilane cross-linked poly-ethylene cable material of the present invention, it consists of by mass parts:
The CABLE MATERIALS that adopts above-mentioned prescription after testing all technical all reaches external similar state of the art.Its processing characteristics and cable surface quality are good.And can realize Quick cross-linking, and enhance productivity, reduce cost.
Embodiment
Below the invention will be further described:
A kind of organosilane cross-linked poly-ethylene cable material of the present invention, it consists of by mass parts:
Its manufacture craft is:
The first step: 1. initiator dicumyl peroxide+Low Density Polyethylene+vinyltriethoxysilane → melting mixing grafting granulation → grafting masterbatch.
135 ℃ of mixing granulator temperature---165 ℃
2. antioxidant 1010+polyethylene+catalyzer di-n-butyltin dilaurate → melting mixing granulation → catalyst masterbatch.
90 ℃ of mixing granulator temperature---120 ℃
Second step: grafting masterbatch+catalyst masterbatch → mixing → extrusion moulding → product warm water crosslinking.
140 ℃ of extrusion temperatures---180 ℃
Adopt after testing the technical performance index of the CABLE MATERIALS that above-mentioned composition and engineering makes can reach following:
