Abstract
The present invention relates to a low-smoke non-halogen low-poison fireproof polyolefin protective sleeve material which mainly uses modified polyolefin resin as a base material. A proper quantity of flame-resistant and effect-increasing materials is added, and an inorganic fireproof agent, antioxidant, a plastic lustering agent and carbon black are added; thereby, the present invention is formed. When the present invention is burnt, obvious smog and harmful gas can not be generated, density is not more than 1.3 g/ cm <3>, a breaking elongation rate can reach more than 300 %, an oxygen index is not less than 35, smoke density is less than 150, and toxicity index is less than 5.0. The present invention has favorable fireproof performance as well as meets the mechanical processing performance of a cable protecting sleeve, and provides a novel material in the field of the cable protecting sleeve material.
Description
The present invention relates to cable and use the material field, definite saying belongs to the cable sheath material.
At present, domestic existing flame retardant cable sheath material, extensively adopt polymer containing halogen or add the compound that halogen flame combines, though these traditional fire retardant materials have good flame retardant property, but when they contact with flame, can produce a large amount of deleterious corrosive hydrogen halides gases and smog, the field staff is suffocated, hinder the fire fighting personnel in time to put out a fire, these toxic gases can corrode instrument and equipment simultaneously, cause " secondary harm ", and the low-smoke and halogen-free flame retardant polyolefin jacket material of now having developed both at home and abroad exists flame retardant properties and machinery, contradiction between the processing characteristics, the i.e. good and mechanical property of flame retardant properties, processing characteristics can't reach defectives such as standard-required.
When purpose of the present invention just provides a kind of the burning amount of being fuming little, do not produce deleterious corrosive gases and the good low-smoke non-halogen low-poisin fire-retarding polyolefin material for protective sleeve of machining property.
It is base-material that the present invention mainly adopts the lower polyolefin resin of degree of crystallinity, add the material modified of necessity base-material is carried out blending and modifying, utilize the resin matrix after the modification, add an amount of packing material, Synergist S-421 95 is made flame-retardant master batch, add inorganic combustion inhibitor, oxidation inhibitor, plastics brightening agent and carbon black again and make this sheath material.
Low-smoke non-halogen low-poisin fire-retarding polyolefin material for protective sleeve of the present invention is made up of 50%～55% base-material, 12%～16% fire-resistant synergistic masterbatch, 28%～33% inorganic combustion inhibitor, 0.4%～0.6% oxidation inhibitor, 0.8%～1.2% plastics brightening agent and 0.8%～1.2% carbon black; Base-material is made up of 85%～89% ethylene-vinyl acetate copolymer, 8%～10% polyethylene, 1.5%～2% dispersion agent, 0.2%～0.4% organo-peroxide, 1%～3% silicoorganic compound; The fire-resistant synergistic masterbatch is made up of 10%～15% base-material, 7%～8% ethylene-vinyl acetate copolymer, 25%～30% silicon-dioxide, 25%～30% soap, 25%～30% silicon rubber; Inorganic combustion inhibitor is made up of 97%～99% metal hydroxides and 1%～3% coupling agent.Wherein, oxidation inhibitor can use four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) acetone] pentaerythritol ester; Also can use 1,1,3-three butane; Also can use 4,4 '-thiobis (3 methy 6 tert butyl phenol); Also can use Tyox B; Also can use 4,4-thiobis phenol.Coupling agent can use phthalate ester coupling agent in the inorganic combustion inhibitor; Also can use aluminate coupling agent; It is that 1.3 μ～2.2 μ, specific surface area are 4m that metal hydroxides in the inorganic combustion inhibitor satisfies particle diameter
2/ g～8m
2The metal hydroxides that/g requires.
Fire retardant mechanism of the present invention is: metal hydroxides heat absorption dehydration when sheath material burns, and the temperature that suppresses polymkeric substance rises, and makes material have flame retardant properties; Polyolefine is the Halogen material, is the pure carbon hydrogen compound, decomposites water and carbonic acid gas during burning, does not produce tangible smog and obnoxious flavour.
Characteristics of the present invention are application of fire-resistant synergistic masterbatch in forming, inorganic combustion inhibitor, make the metal hydroxides addition of its active main inorganic combustion inhibitor be starkly lower than existing like product, solved a guardian technique difficult problem of making in the non-halogen flame-retardant cable, i.e. contradiction between high flame retardant and mechanical property, the processing characteristics.The sheath material proportion of making is not more than 1.3g/cm
3, elongation is greater than 300%, and oxygen index is not less than 35, and poison exponent is less than 5.0, and smoke density has good comprehensive performances less than 150, for the cable jacket material field provides a kind of type material.
The embodiment of the invention:
Example 1: low-smoke non-halogen low-poisin fire-retarding polyolefin material for protective sleeve of the present invention is made up of 51% base-material, 15% fire-resistant synergistic masterbatch, 28% inorganic combustion inhibitor, 0.6% oxidation inhibitor, 0.9% plastics brightening agent and 1.0% carbon black.Wherein, base-material is made up of 86% ethylene-vinyl acetate copolymer, 8% polyethylene, 1.8% polyoxyethylene glycol, 0.3% organo-peroxide, 1% silicoorganic compound; The fire-resistant synergistic masterbatch is made up of 13% base-material, 7% ethylene-vinyl acetate copolymer, 28% silicon-dioxide, 29% soap, 30% silicon rubber; Inorganic combustion inhibitor is made up of 99% aluminium hydroxide and 1% phthalate ester coupling agent.Present embodiment can reach elongation at break 320%, and density is 1.21g/cm
3, oxygen index is 37, poison exponent 2.2, smoke density are 79.
Example 2: low-smoke and halogen-free flame retardant polyolefin jacket material of the present invention is made up of 54% base-material, 16% fire-resistant synergistic masterbatch, 30% inorganic combustion inhibitor, 0.5% oxidation inhibitor, 1.1% plastics brightening agent and 1.0% carbon black.Wherein, base-material is made up of 88% ethylene-vinyl acetate copolymer, 10% polyethylene, 1.6% polyoxyethylene glycol, 0.3% organo-peroxide, 2% silicoorganic compound; The fire-resistant synergistic masterbatch is made up of 12% base-material, 8% ethylene-vinyl acetate copolymer, 26% silicon-dioxide, 27% soap, 28% silicon rubber; Inorganic combustion inhibitor is made up of 98% aluminium hydroxide and 2% phthalate ester coupling agent.Present embodiment can reach elongation at break 310%, and density is 1.2g/cm
