Description
Technical field
The present invention relates to PVC material field more particularly to a kind of heat-proof combustion-resistant PVC injection molding materials.
Background technology
In the prior art, cable industry generally use PVC is as the insulated pipes used on the outside of cable, but due to polyvinyl chloride resin
Self shortcoming, flame retardant property is poor, and on flame burn when can release a large amount of hydrogen chloride gas, hydrogen chloride gas
Have certain toxicity and corrosivity, left with it " self-extinguishment " for having due to it after flame can automatic distinguishing, but it still holds
Easily drip, drippage caused to be lighted, in addition except open fire other than, polyvinyl chloride resin in 100 DEG C or more of hot environment also easily
It decomposes, generate discoloration and releases hydrogen chloride toxic gas simultaneously, with its decomposition of temperature rise and release hydrogen chloride gas
Speed can also further speed up, and when as insulated pipes used on the outside of cable its inevitably can duration work under the high temperature conditions,
And there is certain probability to touch open fire, therefore since the common PVC material of disadvantages mentioned above is difficult to meet the needs of existing industry.
Certainly, there are also the PVC cable injection molding materials with fire retardation in the prior art, but the fire-retardant of its addition helps
Agent, some are that have the fire retardant containing halogen, have larger damaging effect, then flame retardant effect is poor for other；In addition, existing
Some PVC cable insulations tubing is generally harder, it is difficult to be suitable for certain use environments, improve it by adding existing plasticizer
Pliability can then influence the flame retardant property of tubing again；Therefore, being badly in need of one kind can be made both fire-retardant simultaneously with preferable pliability
The flame-proof PVC injection molding material for the PVC insulating materials haveing excellent performance.
Patent Office of the People's Republic of China discloses a kind of application for a patent for invention of flame-proof PVC injection molding material on January 30th, 2018, and application is public
Announcement number is CN107641270A, and discloses a kind of flame-proof PVC on January 23rd, 2018 in Patent Office of the People's Republic of China more in early time
The application for a patent for invention of the preparation method of injection molding material, application notification number are CN107619559A, and both of which is using modified diatom
Soil carries out the improvement of flame retardant property to it, is second to pass through tool one is by the absorption of the ammonium carbonate with flame retardant property
There is the surface of the polysiloxanes fire retardant of flame retarding function to coat, plays the role of isolation burning, but its high temperature resistance does not obtain
To significantly improving, it is heated and is still easy aging.
Invention content
For solve in the prior art, cable industry generally use PVC as the insulated pipes used on the outside of cable, but due to
The self shortcoming of polyvinyl chloride resin, flame retardant property is poor, and can release a large amount of hydrogen chloride gas, chlorine when burning on flame
Change hydrogen and have certain toxicity and corrosivity, left with it " self-extinguishment " for having due to it after flame can automatic distinguishing,
But it is still easy to happen drippage, cause drippage light, in addition except open fire other than, hot environment of the polyvinyl chloride resin at 100 DEG C or more
In also easily decompose, generate discoloration and simultaneously releases hydrogen chloride toxic gas, with temperature rise its decompose and release chlorine
Changing the speed of hydrogen can also further speed up, and when as insulated pipes used on the outside of cable its inevitably can duration in hot conditions
Lower work, and there is certain probability to touch open fire, therefore the problem of common PVC material is difficult to meet existing industry requirement, this
