Description
Technical field
The invention discloses a kind of formula and its processing technology of improvement PVC insulating materials insulating properties.
Background technology
PVC is polyvinyl chloride, is the thermoplastic resin being polymerized by vinyl chloride under initiator effect, is vinyl chloride
Homopolymer.PVC is universal resin, cheap, easy to process, and it and auxiliary agent coordinate obtained product to have in light weight, intensity
Height, chemical proofing is good, and electrical insulation capability and ageing-resistant performance, waterproof anti-corrosion performance are all excellent, is that electric wire is comparatively ideal
Covering material.
In generation twentieth century 30 or 40 years, foreign countries began to use insulating materials of the soft pvc as electric wire, China's PVC cable material
Exploitation start from the fifties, however, with the fast development of communication career, requirement to PVC insulating properties also more and more higher,
Research to the improved technology of PVC insulating properties is also more and more deep.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of improvement PVC insulating materials insulating properties
Formula, the formula contain following component：100 parts of polyvinyl chloride resin, chlorinated paraffin 30-40 parts, clay 1-5 parts, oxidation
Calcium 1-5 parts, magnesia 1-5 parts, zinc stannate 0.1-1.5 parts, hydrotalcite compound 2-5 parts.
An object of the present invention also resides in the processing technology for providing formula of the present invention, comprises the following steps：(1) press
The parts by weight of constitutive material weigh each raw material, and all raw materials are added in mixer and are well mixed, and control mixer temperature is 85
First mixed on low speed 13min at DEG C, then mixed at high speed 2min again, is then once plastified, pelletizing is air-cooled at 150 DEG C；
(2) the air-cooled material of step (1) is subjected to secondary plasticizing at 110 DEG C, packed after pelletizing, air-cooled, detection.
The beneficial effects of the invention are as follows：Insulating materials excellent insulation performance produced by the present invention and combination property stabilization.
Embodiment
Specific embodiment：A kind of formula of improvement PVC insulating materials insulating properties, the formula contains as follows

0.1-1.5 parts, hydrotalcite compound 2-5 parts.
The present invention also resides in the processing technology for providing formula of the present invention, comprises the following steps：
(1) each raw material is weighed by the parts by weight of constitutive material, all raw materials is added in mixer and are well mixed, control is mixed
Conjunction machine temperature first mixed on low speed 13min at 85 DEG C, then mixed at high speed 2min again, is then once plastified at 150 DEG C,
Pelletizing, it is air-cooled；
(2) the air-cooled material of step (1) is subjected to secondary plasticizing at 110 DEG C, packed after pelletizing, air-cooled, detection.
The beneficial effects of the invention are as follows：Insulating materials excellent insulation performance produced by the present invention and combination property stabilization.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
