Abstract
The invention discloses a low-smoke zero-halogen flame retardant polyolefin cracking resisting material. The low-smoke zero-halogen flame retardant polyolefin cracking resisting material is mainly prepared from, by mass, 10-30% of an ethylene-vinyl acetate copolymer, 10-20% of linear low density polyethylene, 5-10% of a compatilizer, 50-70% of a flame retardant, 0.1-0.5% of an antioxidant and 0.5-1% of a lubricating agent. Due to the fact that the low-smoke zero-halogen flame retardant polyolefin cracking resisting material contains zero halogen, the harm to the environment and the human body is reduced; besides, a good mechanical property and good processability are achieved while excellent flame retardance is ensured.
Description
Technical field
The invention belongs to material chemistry technical field, particularly relate to a kind of resistance to cracking of low smoke halogen-free flame-retardant polyolefin
Material.
Background technology
Low-smoke halogen-free polyolefin fire proofing is mainly used in wire cable insulating and sheath, and it is by resin, resistance
Combustion agent, antioxidant, lubricant, cross-linking agent etc. is allocated and is formed.At present, along with people's environmental protection and safety consciousness
Reinforcement, traditional Halogen material can not meet the requirement of people again, and low smoke and zero halogen material has become as
One trend, starts replacement Halogen material gradually.In different occasions, electric wire materials have
Different special requirements, such as at the local electric wire that some Long-term service temperature are higher, it is necessary to
In work process, insulation and the sheath of electric wire can not ftracture, but traditional low smoke and zero halogen material cannot be expired
Foot electric wire is in this requirement on the one hand, so the low-smoke non-halogen flame-retardant being accomplished by developing a kind of resistance to cracking gathers
Olefin material.
Summary of the invention
The defect existed in view of above-mentioned prior art, it is an object of the invention to provide a kind of low-smoke non-halogen flame-retardant and gathers
The alkene material of resistance to cracking.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of low smoke halogen-free flame-retardant polyolefin material of resistance to cracking, its main component by mass percentage, including:
Further, described fire retardant is aluminium hydroxide.
Further, described lubricant is silicone oil.
The preparation method of a kind of low smoke halogen-free flame-retardant polyolefin material of resistance to cracking described above, by described main one-tenth
Divide after preparing according to the weighing of respective mass percent, put into inside banbury, banburying temperature to 140 DEG C blowing,
Through extrusion molding pelletizing, last cool drying, packaging, complete whole preparation section.
Compared with prior art, the invention has the beneficial effects as follows: the low smoke halogen-free flame-retardant polyolefin of the present invention is resistance to
Cracking material, owing to it is without halogen, reduces the harm to environment and human body, this external resistance ensureing excellence
While combustion performance, there is again good mechanical performance and processing characteristics.
Detailed description of the invention
Hereinafter the most in conjunction with the embodiments, the detailed description of the invention of the present invention is described in further detail, so that this
Bright technical scheme is more readily understood, grasps, but the invention is not limited in this.Described in following embodiment in fact

| Aluminium hydroxide | 70% | 54% | 50% |
| Antioxidant | 0.5% | 0.5% | 0.1% |
| Silicone oil | 1% | 0.5% | 0.9% |
The method of the preparation low smoke halogen-free flame-retardant polyolefin material of resistance to cracking described in embodiment 1-3, will mainly become
Divide after preparing according to the weighing of respective mass percent, put into inside banbury, banburying temperature to 140 DEG C blowing,
Through extrusion molding pelletizing, last cool drying, packaging, complete whole preparation section.
According to embodiment 1-3 proportioning, use the low smoke halogen-free flame-retardant polyolefin material of resistance to cracking prepared of this method
The performance of material is as shown in table 2:
Table 2
To sum up, the low smoke halogen-free flame-retardant polyolefin material of resistance to cracking of embodiment of the present invention 1-3 is due to its not Halogen
Element, reduces the harm to environment and human body, has again good while this external fire resistance ensureing excellence
Good mechanical performance and processing characteristics.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art,
Without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into
Protection scope of the present invention.
