Abstract
The invention discloses a halogen-free flame-retardant anti-drip thermoplastic polyurethane (TPU) material. The halogen-free flame-retardant anti-drip TPU material is prepared from the following components in part by weight: 20 to 60 parts of TPU, 11 to 23 parts of SEBS, 18 to 25 parts of flame retardant, 5 to 25 parts of white oil, 1.3 to 2 parts of anti-drip agent and others. The halogen-free flame-retardant anti-drip TPU material solves the problems that the material without the anti-drip function is easy to separate out, the surface is susceptible to scraping white, scaling and glue removal, the processing difficulty is high and the surface is seedy and not smooth, swinging and adhesion occurs, and has low price.
Description
Technical field
The present invention relates to a kind of cable material production technical field, specifically relate to the anti-drip TPU material of halogen-free flameproof that a kind of electric wire and cable jacket is used.
Background technology
Since 08 year, just felt the halogen-free flameproof agitation that countries in the world are blown afloat the responsive a little people of electric wire field work, nowadays drill fiercer and fiercer.TPU provides tear-resistant, wear-resisting and crooked feature.High-and low-temperature resistance is the key of cable performance especially.In addition, chemicals-resistant, hydrolysis and Resistance to microbes, and easily process easy dyeing, so high-grade cable is used for protecting coating material and the purposes of the complicated cable of design also increasingly extensive such as control cables and power cable with TPU.Several years before 08 year all is that Halogen material rather than Halogen add fire retardant material.
It is as follows that TPU is different from the excellent properties of other thermoplastic elastomers: wear resistance is strong, tear strength is strong, bending property is outstanding, tensile strength and elongation at break high, low temperature resistant-35～50 ℃ and resistance to elevated temperatures are low with 150 ℃, long-term compression deformation rate, oil resistant, lubricating oil and the hydrocarbon solvent of aliphatics, oxygen and ozone are had the resistivity anti-aging property.But present TPU material does not possess anti-drip function, and price high, easily separate out, the surface easily scrape white, scaling fall glue, large, the surperficial seediness of difficulty of processing numb not smooth, wave or bonding.
TPU has the plurality of advantages such as low-temperature performance of good elasticity, physical strength, oil resistant, ozone resistance, excellence, but its shortcoming is quite a few, mainly comprises: ageing resistance is poor, poor fire, wet skin friction coefficient are low, easily skid, poor processability, cost are higher.Self does not have flame retardant properties TPU, and during combustion synthesis in air, flame is very violent and with strong black smoke, and has serious drip phenomenon.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of bittern-free flame-proof material is provided, so that the TPU material has anti-drip function, and anti-drip function is difficult for separating out.
Consider the problems referred to above of prior art, according to an aspect disclosed by the invention, the present invention by the following technical solutions:
A kind of halogen-free flameproof is prevented drip TPU material, comprising:
TPU-20 is to 60 parts;
SEBS-11 is to 23 parts;
Fire retardant-18 is to 25 parts;
White oil-5 is to 25 parts;
Anti-dripping agent-1.3 is to 2 parts;
Weighting agent.
In order to realize better the present invention, further technical scheme is:
In one embodiment of the invention, the shore hardness of described TPU is 80～90A.
In one embodiment of the invention, described weighting agent is talcum powder, rises to fill in prescription and does usefulness.
In one embodiment of the invention, described fire retardant is fire retardant 400A, and is not halogen-containing.
The present invention can also be:
In one embodiment of the invention, the content of described weighting agent is 2.5 to 7.5 parts.
Compared with prior art, one of beneficial effect of the present invention is:
Halogen-free flameproof TPU material in the technical scheme of the present invention has the performance of anti-drip function and halogen-free flameproof.Particularly, by add anti-dripping agent and an amount of proportioning thereof in material prescription, carbon-forming performance is excellent in combustion processes, can prevent that material from dripping because of fusing when high-temp combustion.Simultaneously, all material is all not halogen-containing, therefore has the performance of anti-drip function and halogen-free flameproof.
