Abstract
The invention relates to a method for preparing halogen-free flame retardant wire and cable materials, which is characterized in that the halogen-free flame retardant wire and cable materials are made of the following row materials by the percentage in weight: 40-80 per cent of polyethylenes, 5-40 per cent of intumescent flame retardants, 1-30 per cent of auxiliary flame retardants, 0.1-1 per cent of antioxidants, 0.1-1 per cent of lubricants and 2-5 per cent of compatibilizers. The preparation method comprises the following steps: the raw materials are scaled and taken according to a weight proportion; all the materials are put into a high mixing machine to be mixed for 2-5 minutes; the materials are taken out; the mixed materials are put into a screw compressor for extruding granulations. The rotating speed of the screw compressor is 180-600r/min and the temperature is 150-170 DEG C. The invention has the advantages that the new halogen-free and intumescent flame retardant and the auxiliary flame retardant are adopted and matched with an advanced formula design, and a halogen-free flame retardant wire and cable materials are prepared, which conforms with demands of environment protection and is widely used in fields of automotive, electronics and electrics, building and engineering.
Description
Technical field
The present invention relates to a kind of preparation method of low-smoke halogen-free flame-retardant electric wire and cable material, compliance with environmental protection requirements can be widely used in fields such as automobile, electric, construction work, belongs to chemical material technical field.
Background technology
Polyethylene is widely used in the industry-by-industry of current society, higher because of its intensity again, the good tubing that is used to make building trade of winter hardiness with plurality of advantages such as its light weight, inexpensive, excellent electrical insulating property and chemical resistant properties.But its poor fire, oxygen refer to be that the OI value is 17.5 only, are a kind of inflammable macromolecular materials, when making electric wire, cable tubing, under conditions such as high pressure, thermal source, are easy to burning and cause fire.Halogen containing flame-retardant and synergist antimonous oxide flame retardant effect are no doubt fine, but the amount of being fuming is big, and can produce obnoxious flavour.And inorganic combustion inhibitor seriously descends owing to excessive material mechanical performance and the processing characteristics of causing of its addition.
Summary of the invention
The object of the present invention is to provide the preparation method of the little low-smoke halogen-free flame-retardant electric wire and cable material of a kind of amount of being fuming.
For realizing above purpose, technical scheme of the present invention provides a kind of halogen-free flame-retardant wire cable material, it is characterized in that, it is made by following raw materials by weight percent:
Polyethylene 40-80%,
Expansion type flame retardant 5-40%,
Auxiliary flame retardant 1-30%,
Oxidation inhibitor 0.1-1%,
Lubricant 0.1-1%,
Compatilizer 2-5%.
Described polyethylene is a new LDPE (film grade), and its melting index is 5-8g/10min; Described expansion type flame retardant is a halogen-free flame retardants, is ammonium polyphosphate; Auxiliary flame retardant is silico-aluminate, inorganic hydroxide: be aluminium hydroxide or nylon; Described oxidation inhibitor is Hinered phenols antioxidant or composite with phosphite ester kind antioxidant, and its Hinered phenols antioxidant is 1010, and composite with phosphite ester kind antioxidant is 1010 and 168 composite; Described lubricant is a fatty acid metal soap class, is calcium stearate, Zinic stearas, barium stearate or Magnesium Stearate; Described compatilizer is the oligopolymer of the graft polymerization of polypropylene grafted unsaturated acid or acid anhydrides, and for its melting index of PP-G-MAH is 40-150g/10min, percentage of grafting is 0.5-1%.
A kind of preparation method of halogen-free flame-retardant wire cable material is characterized in that, its method is as follows:
(1) weighs raw material by weight percentage;
(2) all raw materials are put into high-speed mixer and mixing 2-5 minute;
(3) discharging;
(4) raw materials mixed is put into screw rod machine extruding pelletization, the rotating speed of screw rod machine is 180-600 rev/min, and temperature is 150-170 ℃.
Expansion type flame retardant has good processing characteristics and flame retardant properties, joins in the polyvinyl resin system and can improve poly fire resistance significantly.
Auxiliary flame retardant and expansion type flame retardant produce synergy, significantly improve the fire resistance of material.
Oxidation inhibitor makes polyethylene possess good processing stability in the course of processing, avoids color and luster, performance to change; Lubricant is used for improving Drawing abillity.
Compatilizer improves the bonding force of each component, disperses each phase component better, improves the over-all properties of material.
Advantage of the present invention is to adopt polyethylene as matrix, and it is little to make a kind of halogen-free flame-retardant wire cable material amount of being fuming.
