Abstract
The invention discloses a heat-shrinkable sleeve free of halogen and red phosphorus, comprising a polyolefin base material, and a fire retardant mixed in the polyolefin base material, wherein the fire retardant is a nitrogen mixed fire retardant; and in percentage by weight, the polyolefin base material accounts for 30-60%, and the nitrogen mixed fire retardant accounts for 40-70%. The heat-shrinkable sleeve free of halogen and red phosphorus is pollution-free and capable of meeting requirements on environmental protection because of being mixed with the nitrogen mixed fire retardant which can replace traditional halogen-containing fire retardant and red phosphorus.
Description
Technical field
The present invention relates to a kind of Halogen does not have the heat-shrinkable T bush of red phosphorus.
Background technology
Existing heat-shrinkable T bush when making, generally is mixed with halogen containing flame-retardant and red phosphorus, can pollute to environment, can not meet high-end environmental protection requirement.
Summary of the invention
The technical problem that the present invention will solve provides a kind of Halogen that can compliance with environmental protection requirements does not have the heat-shrinkable T bush of red phosphorus.The present invention realizes through following technical scheme:
Halogen of the present invention does not have the heat-shrinkable T bush of red phosphorus, comprises polyolefin substrate, and is blended in the fire retardant in the polyolefin substrate, and said fire retardant is that fire retardant mixes in nitrogen system; It is 30%～60% that said polyolefin substrate accounts for weight percent, and fire retardant mixes in said nitrogen system, and to account for weight percent be 40%～70%.
As preferably, said polyolefin substrate is Injecatable EVA Copolymer or the mixture of the two.
As preferably, it is that 55% said nitrogen system mixes fire retardant to account for weight percent be 45% that said polyolefin substrate accounts for weight percent.
Halogen of the present invention does not have the heat-shrinkable T bush of red phosphorus, mixes fire retardant owing to be mixed with nitrogen system, and fire retardant mixes in nitrogen system can substitute traditional halogen containing flame-retardant and red phosphorus, does not pollute, and can meet environmental protection requirement.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the sectional view that Halogen of the present invention does not have the heat-shrinkable T bush of red phosphorus.
Embodiment
As shown in Figure 1, the left side is for before shrinking, and the right is for after shrinking, and Halogen of the present invention does not have the heat-shrinkable T bush of red phosphorus, comprises polyolefin substrate, and is blended in the fire retardant in the polyolefin substrate, and said fire retardant is that fire retardant mixes in nitrogen system; It is 30%～60% that said polyolefin substrate accounts for weight percent, and fire retardant mixes in said nitrogen system, and to account for weight percent be 40%～70%.Mix fire retardant owing to contain nitrogen system in the sleeve pipe, fire retardant mixes in nitrogen system can substitute traditional halogen containing flame-retardant and red phosphorus, does not pollute, and can meet environmental protection requirement.
Wherein, said polyolefin substrate is Vilaterm, Injecatable EVA Copolymer or the mixture of the two.
Embodiment one:
It is 55% that said polyolefin substrate accounts for weight percent, and fire retardant mixes in said nitrogen system, and to account for weight percent be 45%.Above material fully mixes and forms.
Embodiment two:
It is 60% that said polyolefin substrate accounts for weight percent, and fire retardant mixes in said nitrogen system, and to account for weight percent be 40%.Above material fully mixes and forms.
Embodiment three:
It is 57% that said polyolefin substrate accounts for weight percent, and fire retardant mixes in said nitrogen system, and to account for weight percent be 43%.Above material fully mixes and forms.
Halogen of the present invention does not have the heat-shrinkable T bush of red phosphorus, mixes fire retardant owing to be mixed with nitrogen system, and fire retardant mixes in nitrogen system can substitute traditional halogen containing flame-retardant and red phosphorus, does not pollute, and can meet environmental protection requirement.
The foregoing description; It is an instance of the present invention; Be not to be used for limiting enforcement of the present invention and interest field, all equivalences of being done according to the described structure fabrication process method of patent protection scope of the present invention change and modify, and all should be included in the claim of the present invention.
