Abstract
The invention discloses a low-smoke flame-retardant polyvinyl chloride cable material. The cable material is characterized in that the cable material is composed of the following raw materials, by weight, 100 parts of polyvinyl chloride resins, 15-20 parts of filling agents, 50-55 parts of plasticizers, 5-7 parts of flame-retardant agents, 6-7 parts of composite stabilizing agents, 0.5-2 parts of pigments and 1-2 parts of lubricants. The cable material is advantageous in that three cooperative flame-retardant agents of tricresyl phosphate, antimonous oxide and molybdenum sesquioxide in appropriate amounts are used for preparing the low-smoke flame-retardant polyvinyl chloride cable material, and the defect of poor flame-retardant effects because of usage of single flame-retardant agent is overcome. The oxygen index of the prepared polyvinyl chloride cable material can reach 32.5. The cable material has low smoke amount and no smolder, and has low-smoke and flame-retardant effects. The good properties of the polyvinyl chloride cable material are retained, and the cost is lowered.
Description
technical field
The present invention relates to a kind of low-smoke and flame retardant polyvinyl chloride cable material and preparation method thereof.
background technology
Along with economic fast development, Highrise buildings, underground works and factory etc. has all been used a large amount of cables.Due to the intensive laying of Cable Group, crisscross, exist various safety problem hidden danger, once presence of fire is puted out a fire to save life and property very difficult.Itself has self-extinguishing polyvinyl chloride cable material, but often adds a large amount of softening agent in the course of processing, can improve the combustibility of cable grain.The burning of polyvinyl chloride cable material can produce a large amount of toxic smogs.These smog can allow people die of asphyxiation, and have also greatly hindered the expansion of fire-fighting salvaging simultaneously.Therefore fire-retardant to polyvinyl chloride cable material, presses down cigarette and requires just to seem even more important.
summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned cable, a kind of low-smoke and flame retardant polyvinyl chloride cable material and preparation method thereof is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of low-smoke and flame retardant polyvinyl chloride cable material,
It is characterized in that it is that raw material by following weight parts proportioning forms: polyvinyl chloride (PVC) RESINS 100 weight parts, weighting agent 15-20 weight part, softening agent 50-55 weight part, fire retardant 5-7 weight part, one package stabilizer 6-7 weight part, pigment 0.5-2 weight part, lubricant 1-2 weight part.
Preferably, described softening agent is the mixture of dioctyl phthalate (DOP) and any proportioning of Tritolyl Phosphate.
Preferably, described weighting agent is selected from the mixture of nano-calcium carbonate and aluminium hydroxide a kind of or two kinds of any proportionings wherein.
Preferably, described fire retardant is selected from the mixture of Tritolyl Phosphate, antimonous oxide and three kinds of any proportionings of molybdenum sesquioxide.
Preferably, described one package stabilizer is calcium zinc stabilizer.
In order to realize above-mentioned CABLE MATERIALS, the present invention also provides a kind of preparation method of low-smoke and flame retardant polyvinyl chloride cable material,
It is characterized in that: according to above-mentioned raw materials formula, prepare burden, first that polyvinyl chloride (PVC) RESINS, weighting agent and mix lubricant is even, again softening agent, fire retardant, one package stabilizer and pigment are added to above-mentioned mixed solution, then extruding pelletization in the screw extrusion press that is 90mm at diameter, control temperature is 110-175 ℃ and obtains goods.
The invention has the advantages that: the present invention adopts Tritolyl Phosphate, antimonous oxide and three kinds of molybdenum sesquioxides appropriate
The fire retardant coordinating is for the preparation of low-smoke and flame retardant polyvinyl chloride cable material, overcome the shortcoming of using single fire retardant weak effect, polyvinyl chloride cable material oxygen index prepared by the present invention can reach 32.5, the amount of being fuming is few, without glowing,, to reach the effect of low-smoke and flame retardant, not only retained the superperformance of polyvinyl chloride cable material but also can reduce cost.
Embodiment
In order to make the public can fully understand technical spirit of the present invention and beneficial effect; applicant will describe in detail the specific embodiment of the present invention below; but applicant is not the restriction to technical scheme to the description of embodiment, anyly according to the present invention design, changes in the form rather than substance all and should be considered as protection scope of the present invention.
A low-smoke and flame retardant polyvinyl chloride cable material, it is that raw material by following weight parts proportioning forms (kg): polychlorostyrene second
Olefine resin 100, weighting agent 15-20, softening agent 50-55, fire retardant 5-7, one package stabilizer 6-7, pigment 0.5-2, lubricant 1-2.
Described softening agent is the mixture of dioctyl phthalate (DOP) and any proportioning of Tritolyl Phosphate.
Described weighting agent is selected from the mixture of nano-calcium carbonate and aluminium hydroxide a kind of or two kinds of any proportionings wherein.
Described fire retardant is selected from the mixture of Tritolyl Phosphate, antimonous oxide and three kinds of any proportionings of molybdenum sesquioxide.
Described one package stabilizer is calcium zinc stabilizer.
A kind of preparation method of low-smoke and flame retardant polyvinyl chloride cable material is, according to above-mentioned raw materials formula batching, first by polychlorostyrene second
Olefine resin, weighting agent and mix lubricant are even, then softening agent, fire retardant, one package stabilizer and pigment are added to above-mentioned mixed solution, extruding pelletization in the screw extrusion press that is then 90mm at diameter, and control temperature is 110-175 ℃ and obtains goods.
Embodiment 1
The composition of fire retardant plays conclusive effect to the performance of polyvinyl chloride cable material of the present invention.Therefore, the present embodiment is investigated and is used single a kind of fire retardant and mix the impact of three kinds of fire retardants on low-smoke fireproof cable material property energy, and its test conditions and detected result are as shown in table 1 below:
The single a kind of fire retardant of table 1 and three kinds of fire retardants of mixing are to low-smoke fireproof cable material performance comparison test
From above-mentioned table 1, the effect of a kind of fire retardant of single use is undesirable.By trimethylbenzene lipoprotein of phosphoric acid, ANTIMONY TRIOXIDE SB 203 99.8 PCT and three kinds of appropriate cooperations and use of molybdic oxide, it is fire-retardant and smoke suppressing effect best.
