Abstract
A PVC halogen-free flame-retardant plastic particle is prepared from 100 parts of PVC, 22 parts of DOP, 5-10 parts of aluminum oxide, 2-15 parts of magnesium oxide and 1-5 parts of inhibitor. The cable material is difficult to combust and can prevent combustion, the flame retardant rating can reach the V-0 level, toxic substances containing halogen are not prone to being produced during combustion, smoke is not prone to being produced, and the PVC halogen-free flame-retardant plastic particle can be suitable for high-voltage and low-voltage electric cables.
Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of PVC halogen-free fire retardant plastic grain.
Background technology
Power cable generally all can increase flame-retardant sheath material at skin when using; amount of heat is being gathered and presence of fire to prevent cable; and the cigarette produced when material burns just; these cigarettes not only produce a large amount of toxic substances; and people can be caused to suffocate; this is only the principal element of the death because of fire, and therefore research has the cable protective sleeve of good flame-retardance energy is the important topic preventing power cable fire.
Summary of the invention
The object of this invention is to provide a kind of halogen-free fire retardant plastic grain.
In order to solve in background technology existing problem, the present invention adopts technical scheme as follows: it is that PVC100 part, DOP22 part, aluminum oxide 5-10 part, magnesium oxide 2-15 part, antiaging agent 1-5 part are formulated by raw material.
The present invention has following beneficial effect:
The present invention have be difficult to burn can stop simultaneously burning performance, flame retardant rating can reach V-0 level, not easily produces halogen-containing toxic substance, also not easily produce flue dust during burning, is applicable to high-low pressure power cable and uses.
