Change, has serious influence to the characteristic of product；That there are crosslinking times is long for silane cross-linking method, and technological operation is complex, and product is resistance to
Temperature, the defects of stress levels are not high.
Traditional handicraft shares a head using the extrusion equipment of 65,90 and 150 3 models and passes through 6 sections of 350 degree of vulcanizations
Pipeline squeezes out cross linked insulation core, then by water cooling down, raw as standard requirements of the market user to cable gradually increase
The insulated wire cores performance indexes that output is come is not easy to reach standard requirements, be easy to cause the degree of eccentricity of insulation unqualified, squeezes out
Equipment adds the electricity consumption of 6 sections of heating pipes big, and Fei Rengong, speed of production are slow, waste is big, occupation area of equipment is big, second-rate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method that ultraviolet light irradiation cross-linking prepares high voltage cable, techniques
Simply, it ensure that the degree of eccentricity of insulation can achieve higher standard requirements, do not have to carry out by 6 sections of 350 degree of curing tubes again
Crosslinking greatly saves electric energy, and cost of labor saves 2/3rds, and speed of production can be improved 50% or more, equipment land occupation
Area saves 50% or more, improves the quality of product.
In order to solve the above technical problems, the technical solution used in the present invention is:
A kind of method that ultraviolet light irradiation cross-linking prepares high voltage cable, comprising the following steps: (1) be heated to 65 type extruders
85-118 DEG C, 90 type extruders are heated to 75-112 DEG C, and 150 type extruders are heated to 85-160 DEG C, and extrusion die is cleaned out
And it assembles；(2) conductor first passes through 65 type extruders and squeezes out internal shield, then squeezes out insulating layer by 150 type extruders, passes through
Irradiation cross-linking apparatus is crosslinked, and is then squeezed out external shielding layer by 90 type extruders again, is finally entered sink and cooled down；
(3) insulated wire cores water cools down, tooling shaft in rotation, packaging.
The irradiation cross-linking apparatus is ultraviolet light irradiation cross-linking case.
Insulation is crosslinked by the irradiation of ultraviolet light irradiation cross-linking case LED ultraviolet light radiation in step (2), speed is
60-90m/min。
The ultraviolet light irradiation cross-linking case includes cabinet, power supply and LED ultraviolet lamp tube, and LED ultraviolet lamp tube is located in the box body,
LED ultraviolet lamp tube length direction is identical as cable movement direction, and 14 LED ultraviolet lamp tubes are installed side by side and are encircled into circular electric
Cable channel, power supply are the power supply of LED ultraviolet lamp tube.
Insulating layer is made of high density polyethylene (HDPE), antioxidant and crosslinking agent, antioxidant, crosslinking agent and high density polyethylene (HDPE)
Weight ratio is 1:1-5:150-400.
The beneficial effects of adopting the technical scheme are that using 65 type extruders, 90 type extruders and 150 types
Three equipment of extruder carry out photocuring using cross linked insulation line crust of the ultraviolet light irradiation cross-linking case to three head extrusions,
It is cooling by water again, effective control has been reached to the insulated wire performance indexes produced, has guaranteed the degree of eccentricity of insulation
It can achieve higher standard requirements, without being crosslinked again by 6 sections of 350 degree of curing tubes, greatly save electric energy, people
Work cost savings 2/3rds, speed of production can be improved 50% or more, and occupation area of equipment saves 50% or more, improves production
The quality of product.
