Description
(1) technical field
The present invention relates to a kind of halogen-free flame-retardant master batch.
(2) background technology
In order to improve safety in utilization, make PP carry out a large amount of research and developments to polyacrylic fire-retardantization both at home and abroad in widely field application, the exploitation of fire-retardant PP mainly is to add fire retardant to make PP have flame retardant effect in PP.Conventional flame retardant is halogenated flame retardant, but halogenated flame retardant can send the dense smoke of black when burning, produce toxic substance and go out Dioxins, serious threat physical environment and HUMAN HEALTH, European Union has forbidden containing the product immigration of this type of material at present, so halogenated flame retardant is just progressively replaced by the novel environment friendly fire retardant.
The chemical phosphorus expanding fire retardant is generally take P, N and C as main nucleus, be applicable to the fire-retardant of multiple combustible polymers, in the polymer combustion process, drip without molten drop, also have good resistance to flame in the flame even be exposed to for a long time, and Halogen, without antimony, low cigarette, low toxicity, non-corrosiveness gas.
But expansion type flame retardant has the following disadvantages: 1. the polarity of expansion type flame retardant and polymkeric substance differs greatly and causes its consistency poor, and the electrical property of polymkeric substance and insulating property are descended to some extent, and especially mechanical property such as intensity and toughness significantly descend; 2. the expansion type flame retardant water absorbability is strong.Such as the APP/PER/MA Intumescent Retardant System, the not only easy moisture absorption of poly-hydroxy PER, and alcoholysis easily occurs between each composition, cause the flame-retardant polymer poor water resistance; 3. common, the relative molecular mass of expansion type flame retardant is little, easily migrates to polymer surfaces, thereby causes the poor mechanical property of flame retardant products, and especially aesthetic appearance is poor; 4. processing difficulties, the expanding fire retardant small molecules is more, and poor heat stability is heated and is easily decomposed, and adds to make man-hour NH3 decompose out, causes the tie rod surfaces of tacky, is difficult for processing.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing expansion type flame retardant, the invention provides a kind of good mechanical performance, water-tolerant, physical and mechanical properties good, be easy to process the halogen-free flame-retardant master batch of depositing.
The technical scheme that the present invention solves its technical problem is: a kind of halogen-free flame-retardant master batch is characterized in that this halogen-free flame-retardant master batch is comprised of according to mass parts following raw materials according:
Halogen-free flame retardants: 30～80 parts;
Polyolefin carrier: 15～69.7 parts;
Silicone oil: 0.2～2 part;
Coupling agent: 0.1～3 part;
In the preparation, at first proportionally take by weighing above-mentioned raw materials, then polyolefin carrier, silicone oil, coupling agent are added stirring at low speed 3min in the homogenizer, add at last halogen-free flame retardants high-speed stirring 5min; The raw material that stirs is changed in the two-stage vacuum twin screw extruder, and extruding pelletization, extruder temperature are set as 100～130 ℃.
Preferably, described halogen-free flame retardants is phosphor-nitrogen expansion type combustion inhibitor, it is mixed according to arbitrary proportion by acid source, source of the gas, charcoal source and forms, and the ratio between acid source, source of the gas, the charcoal source can effect of the present invention not make a significant impact, and therefore can mix by arbitrary proportion.
Preferably, described acid source is one of ammonium polyphosphate, phosphoric acid, Vanadium Pentoxide in FLAKES, boric acid; Described source of the gas is any one in trimeric cyanamide, Dyhard RU 100, ammonium polyphosphate, amine borate, the Dyhard RU 100 formaldehyde resin; Described charcoal source is any one in tetramethylolmethane, sorbyl alcohol, the Mierocrystalline cellulose.
Preferably, described polyolefin carrier be any one or both in LDPE, the propylene-based elastomeric with any than mixing.
Preferably, described silicone oil is any one in methyl-silicone oil, hydroxy silicon oil, the amido silicon oil.
Preferably, described coupling agent is molecular weight greater than 800 solid-state titanate coupling agent or molecular weight greater than 800 solid-state aluminate coupling agent.
Preferably, when carrying out the stirring of polyolefin carrier, silicone oil, coupling agent, the rotating speed of homogenizer is 500 rev/mins, and the rotating speed of homogenizer is 800 rev/mins behind the adding halogen-free flame retardants.
Beneficial effect of the present invention is: this master batch is processed under 100～130 ℃ of conditions, and processing temperature is far below the decomposition temperature of fire retardant, and the performance that this master batch can intactly be preserved fire retardant is not destroyed, and is easy to processing and preservation.This halogen-free flame-retardant master batch selects polyolefin carrier to do body material, has advantages of that the fire retardant of making is easy to disperse, flame retarding efficiency is higher.This fire-retardant master granule can directly stir injection moulding with resin and also can be used as fire retardant and join in the forcing machine and use as halogen-free flame retardants.
The auxiliary agents (especially adopting toughness LDPE or propylene-based elastomeric higher and that be easy to process is vector resin) such as coupling agent, silicone oil are arranged in the invention, make fire retardant better with resin compatible.After fire-retardant master granule and polypropylene, polyethylene carried out blend, material not only had good flame retardant effect but also has higher toughness and intensity.Owing to utilizing silicone oil and coupling agent that fire retardant is carried out surface treatment, the wetting ability of fire retardant reduces greatly, makes in the material not facile hydrolysis and separating out of fire retardant, so material has excellent water tolerance.
