Description
Technical field
The invention belongs to electric wire field, is related to a kind of two-step method silane non-halogen flame-proof cross-linking cable material of polyolefin and system
Preparation Method.
Background technology
Polyvinyl resin has good mechanical performance, insulating properties, lower temperature resistance and processability, is widely used in electricity
Line field of cables.But temperature is low, environmental stress crack resistance is poor and low (LOI=18%) pole of itself oxygen index (OI) because it is used
Easy firing, thus greatly limit its use range.
The cross-linking modified technology of polyethylene wire and cable, improves it and uses temperature and environmental stress crack resistance, poly- second
Alkene crosslinking mainly has three kinds of modes, i.e. peroxide chemical cross-linking method, silane cross-linking method and irradiation crosslinking.Metal hydroxidess
Aluminium hydroxide (Al (OH)3), magnesium hydroxide (Mg (OH)2) there is good low cigarette, nontoxic, fire resistance and cheap, widely
It is applied to low smoke halogen-free flame-retardant polyolefin wires and cables industry.
Irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin wire cable material is made and need after cable ability after irradiation apparatus irradiation
Crosslinking, and the equipment price is expensive, secondly, cross-linking radiation is only applicable to thinner thickness, the electric wire of structure circular symmetry.Silicon
Alkane cross-linking method processing technique is simple, and one-time investment is few, and energy consumption is low, flexible operation, thus is looked forward to by the production of vast electric wire
The concern of industry.
At present, silicane crosslinking flame retardant polyolefin cable material with low smoke halogen is using one-step method and two-step method, Chinese patent
CN102093625A describes a kind of natural-crosslinked cable material of polyolefin of low smoke and zero halogen one-step method silanes, and composition of raw materials is by fire-retardant mother
Material, catalyst masterbatch and copulation mixture composition.One-step technology is simple, and energy consumption is low, but carries out graft reaction to flame-retardant master batch, instead
Should be complicated, it is difficult to control, stability is poor.
The method of Chinese patent CN102304254A two-step method silicane crosslinking flame retardant polyolefin cable material with low smoke halogen, first
Step prepares silane grafted polyethylene A material and catalytic crosslinking B material, and second step expects silane grafted polyethylene A, fire retardant and auxiliary agent are total to
It is mixed.Silane grafted polyethylene A material and inorganic combustion inhibitor are blended into pelletize, the resin stream after Silane Grafted in second step preparation process
Dynamic property declines, and adds the inorganic combustion inhibitor measured at high proportion, cause to be extruded during unwrapping wire it is difficult, and with the height containing water of crystallization
When the fire retardant of ratio addition is coextruded, be susceptible to precrosslink reaction, prevent the preparation process of electric wire from it is continuous with
And line face smoothness is poor.Reduce pre-cross-linking phenomena, solve the electric wire unwrapping wire course of processing processability and line face it is smooth be urgently
Problem to be solved.
