Description
Technical field
The present invention relates to a kind of mixing method of actual production insulating material of polyethylene.It belongs to sample preparation technology field,
Suitable for producing the sample of suitable polyethylenes insulating layer superior performance.
Background technique
With the development of domestic economy, the production of polyethylene wire and cable no longer meets the needs of power industry.Although
Polyethylene has obtained cable industry by the performances such as its outstanding electrical insulation capability, good chemical-resistance, easy to process
Height favor, and be widely used in the insulation of cable and the covering material of sheath.But its fusing point is lower, cannot work compared with
Under high environment temperature, so it can not preferably be applied in cable industry.And the mechanical strength of polyethylene is lower, this
Limit its extensive use.No matter in terms of electrical performance or in terms of mechanical property, existing production technology cannot be produced
Meet the cable insulation of development out.
Ultraviolet light cross-linking polyethylene new technology with its industrial equipment simple, small investment, it is easily operated, easy to maintain, to ring
To the damage of polyethylene ontology during border is pollution-free, security protection is not harsh, volume production rate is high, operating cost is low and ultraviolet light cross-linking
Hurt the advantages that small, extensive use has been obtained in its related fields, passes through the industry processes being applied to cable.Though
Right UV crosslinking polyethylene insulation is applied well, but produces the method efficiency of this insulation again without being mentioned
Height can preferably make this new technology be widely used so a kind of new method is needed to improve production efficiency.
Summary of the invention
In view of the above-mentioned problems, solving base-material the invention discloses a kind of insulation pellet mixing method mixes uneven, mechanics
The problems such as performance, insuperior electric property.
The present invention is a kind of insulation pellet mixing method, which comprises the following steps: a. proportionally prepares one
Quantitative mixing sample, i.e. polyethylene, crosslinking agent and ultraviolet absorbing agent；B. oven temperature is set as 200 DEG C, is put into and has been prepared
The sample (under air-proof condition) of ratio dries nearly 4h.During this, is once rocked every half an hour, be then allowed to stand 12h；c.
It is added certain antioxidant before being squeezed out with extruder, the temperature that four sections every section of extruder is set as 130 DEG C, and 140 DEG C, 160 DEG C,
180℃.Extruding sheet mixture；D. mixture is pressed into using vulcanizing press the small pieces of 1mm thickness, then carries out ultraviolet light
Radiation.Plaques are finally cut into dumbbell shaped with sheet-punching machine.
Preferably, extruder used in step c is electromagnetic dynamic plasticizing extruder, polymer plasticization squeezes out overall process
It is completed in the rotor internal cavity of driving motor.Each section in figure are as follows: 1- ventilation opening；2- screw rod；3- barrel；4- rotor；5- stator；
6- base；7- hopper.
Preferably, belonging to laboratory hand sheet punching apparatus using sheet-punching machine in step d, convenient for rushing polyethylene kind sample
It is cut into standard regulation sample.
Disclosed insulation pellet mixing method, which is kneaded, to be uniformly mixed, and good dispersion is determined to stretch by force with excellent
Mechanical properties such as degree, tensile strength, elongation at break, and reduce environmental pollution, save resource, equipment investment it is small, it can be achieved that
Industrialized production.
Detailed description of the invention
Following specific implementation and attached drawing of the invention are described in detail for ease of explanation,.
Fig. 1 is the electromagnetic dynamic plasticizing extruder device in step c of the present invention.
Specific embodiment
Specific embodiments of the present invention are broadly divided into following steps:
1. proportionally preparing a certain amount of mixing sample, i.e. polyethylene, crosslinking agent and ultraviolet absorbing agent；
2. setting oven temperature as 200 DEG C, the sample (under air-proof condition) for being put into the ratio of having prepared dries nearly 4h.During this,
It is once rocked every half an hour, is then allowed to stand 12h；
3. certain antioxidant is added before being squeezed out with extruder, totally four sections and every section of temperature is set as 130 DEG C to extruder,
140 DEG C, 160 DEG C, 180 DEG C.Extruding sheet mixture carries out envelope preservation；
4. mixture is pressed into using vulcanizing press the small pieces of 1mm thickness, ultraviolet light cross-linking radiation is then carried out.Finally with punching
Plaques are cut into dumbbell shaped by piece machine, are done heat and are extended experiment, test the degree of cross linking.
The present invention is not limited to above-mentioned specific embodiment, and persons skilled in the art are disclosed interior according to the present invention
Hold, the contents of the present invention or all using design structure of the invention can be implemented using other a variety of specific embodiments
And thinking, simple change or change are done, protection scope of the present invention is both fallen within.
