Abstract
The invention discloses a safe environment-friendly low-smoke halogen-free flame retardant wire. The safe environment-friendly low-smoke halogen-free flame retardant wire comprises the following components in percentage by weight: 20%-30% of ethylene-vinyl acetate, 5%-10% of POE (Polyolefin Elastomer) plastic, 5%-10% of polyethylene, 50%-60% of hydroxide fire retardant, 0.5%-1% of silane coupling agent and 1.3% of other impurities. The safe environment-friendly low-smoke halogen-free flame retardant wire manufactured according to the formula has the advantages of having the flame retardant property being capable of preventing flame spread and being capable of ensuring that cables continuously transmit electric energy and communication signals, as well as the advantages of having low smoke amount, releasing few poisonous gases, generating gases with low corrosivity during burning, thus reducing the damage to human bodies, instruments and equipment.
Description
Technical field
The invention discloses a kind of safety, environmental protection low-smoke non-halogen flame-retardant line and manufacturing process.
Background technology
Along with China's rapid economic development, electric network reconstruction, infrastructure construction upgrading etc. will be quickened one's step, and the demand of electric wire product is constantly risen, and the requirement to the cable loop guaranteed cost simultaneously also will improve constantly.Flame-retardant electric wire and cable can be divided into general flame-retardant electric wire and cable, low smoke and low halogen electric wire and low-smoke halogen-free flame-retardant electric wire and cable usually.At present China's flame-retardant electric wire and cable product is fire-retardant based on Halogen, and this electric wire discharges a large amount of dense smoke and corrodibility halogenide when burning, causes casualties and corrodes various device, i.e. so-called " secondary disaster ".
Summary of the invention
In order to overcome above-mentioned shortcoming of the prior art, the object of the present invention is to provide a kind of safety, environmental protection low-smoke non-halogen flame-retardant line and manufacturing process, during burning its to have the amount of being fuming few, it is few to discharge toxic gas, reduces the advantage to the injury of human body and plant and instrument.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of safety, environmental protection low-smoke non-halogen flame-retardant line are pressed column weight amount per-cent and are comprised ethylene-vinyl acetate 20～30%, POE plastics 5～10%, polyethylene 5～10%, oxyhydroxide fire retardant 50～60%, silane coupling agent 0.5～1%, other impurity are 1.2～1.4%.
As further being set to of such scheme: press column weight amount per-cent and comprise ethylene-vinyl acetate 23～27%, POE plastics 7～9%, polyethylene 7～9%, oxyhydroxide fire retardant 53～57%, silane coupling agent 0.7～0.9%, other impurity are 1.3%.
Press column weight amount per-cent and comprise ethylene-vinyl acetate 26%, POE moulds 7.5%, polyethylene 8.4%, and oxyhydroxide fire retardant 56%, silane coupling agent 0.8%, other impurity are 1.3%.
The superpolymer that described POE plastics are ethene and butylene or the superpolymer of ethene and octene.
Described oxyhydroxide fire retardant is magnesium hydroxide or hibbsite.
The preparation method of a kind of safety, environmental protection low-smoke non-halogen flame-retardant line, (1) chosen material is got conductor, PVC material; (2) pour low-smoke halogen-free material into loading hopper, and to preheating heat be added to 140～150 the degree; (3) open heater switch, heat for head and barrel, open the hopper feed door, open main frame, sizing material is slowly extruded; (4) open extruder and make its plastic emitting, and combine with lead; (5) take-up rolling.
After the present invention adopts said ratio and technology, the advantage of the safety that produces, environmental protection low-smoke non-halogen flame-retardant line: have the flame retardant properties that can stop propagation of flame, and can keep cable and continue electric energy transmitting and communication signals, and when burning, also should have low-smoke, it is few to discharge toxic gas, it is low to produce gaseous corrosion, reduces the advantage to the injury of human body and plant and instrument, makes cable have Halogen, low cigarette, performance such as fire-retardant.
