Abstract
The invention relates to the technical field of polymer materials, in particular to a polyvinylchlorid electrical equipment plug material filled with modified 6000-mesh superfine triple superphosphate. The polyvinylchlorid electrical equipment plug material is manufactured by polyvinyl chloride (PVC), plasticizers, stabilizers, processing additives, modifiers, 6000-mesh heavy calcium carbonate, light calcium carbonate and the like. The preparation method comprises the steps: a PVC mixed material is obtained through completely and uniformly mixing the components through a high-speed mixing machine, and then the PVC mixed material is extruded by an extruding machine to granulate to obtain the polyvinylchlorid electrical equipment plug material filled with modified 6000-mesh superfine triple superphosphate. The polyvinylchlorid electrical equipment plug material filled with modified 6000-mesh superfine triple superphosphate has higher dispersivity and compatibility , can improve the runnability and the processability of a system, endows physical mechanical property and ageing resistance performance, and lowers the cost .
Description
Technical field the present invention relates to a kind of appliance plug material of a kind of SE of polymeric material field.Be specifically related to the filling-modified of SE appliance plug material.
Often use ordinary calcium carbonate (below 800 orders) in the background technology traditional cable material, very poor with the resin matrix consistency, addition is limited, and performance of products is had many detrimentally affects.
The objective of the invention is to overcome the compound of common inorganic particulate and organic substance, the shortcoming that in the processing and preparing process, exists.Because common lime carbonate is prone to cause the boundary defect of two kinds of materials when in superpolymer, using; Fill a certain amount of modification 6000 order superfine powders; Make it become functional filler, eliminated and in organism, disperseed inequality, the boundary defect that filler and matrix exist by general weighting agent; Improved the mechanical property of composite product, thereby made product obtain better to strengthen toughening effect.
Summary of the invention the present invention realizes through following scheme:
The filling-modified polyvinyl chloride cable material of modification 6000 order ultrafine heavy calciums, in following ratio proportioning (weight percentage):
PVC RESINS 50～70%;
Softening agent 20～35%;
Stablizer 2～5%;
Processing aid 1～3%;
Weighting agent 5～9%;
6000 order ultrafine heavy calciums 2～5%;
Modification agent 1～3%.
And stablizer can be the kind commonly used of existing PVC stabilizer, as: the plumbous and dibasic Lead Phosphite mixing of tribasic lead sulfate or dibasicity phthalic acid.
And, for reducing cost, can also outer join a spot of softening agent, for example: clorafin, phenyl alkylsulfonate 50 etc.
And, according to processing characteristics, can also add the properties-correcting agent of (in base-material) 0.5～1%, for example: the brightener that adds lustre to, to improve processing fluidity, can also add the UV light absorber of (in base-material) 0.2～0.3%, can improve weathering resistance after allocating into.
The advantage that the present invention compared with prior art has is: when common weighting agent is filled into certain proportion; Can not satisfy the physicals requirement of its product fully; But after adding a certain amount of modification 6000 order ultrafine heavy calciums, its each item performance index all can meet the quality index requirement, in addition; Also reduced the relevant performance index of cost and its and increased (as: tensile strength, elongation at break), and cost is descended to some extent.
The present invention is with the 6000 order ultrafine heavy calciums of the particle diameter≤2 μ m of surface treatment agent and 90% component as filling-modified SE appliance plug material and preparation method thereof; The improved technology of taking to dehumidify; The inorganic material powder that makes interpolation by inorganic nature to organic sex reversal; By the surface hydrophilic oleophobic property; Change lipophilic-hydrophobic property into and successfully solved 6000 order ultrafine heavy calciums that chestnut when adding is reunited and the problem of poor dispersion, improved intermiscibility, dispersiveness, flowability and processing characteristics after powder and the mixed with resin.
The present invention is under the prerequisite that guarantees the plastics performance, and 6000 order ultrafine heavy calciums can be used for producing common pipe fitting, tubing, plastic box, pre-buried material, and addition can reach more than 80%, greatly reduces production cost.
Embodiment the present invention further details through following examples, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
Embodiment: the appliance plug of 6000 order ultrafine heavy calcium modifications is formed and weight is:
Polyvinyl chloride resin 50～60kg
DOP 20～25kg
Clorafin 2.2～3.8kg
Tribasic lead sulfate 1.8～3.0kg
Acrylic process aids 0.4～1.2kg
PVC external lubricant 0.2～1.0kg
Modification agent 1.0～2.0kg
Weighting agent 5～20kg
6000 order ultrafine heavy calciums, 2～5kg
Its preparation method is:
6000 order ultrafine heavy calciums are put into high mixer; High-speed stirring begins dehumidifier when being mixed into 120～180 ℃ of temperature, temperature reaches 100～110 ℃ and adds phthalates and paraffin, mixes and stirs 5～8 minutes; Put into cold mixer temperature to 30～50 ℃ discharging then, be modification 6000 order ultrafine heavy calciums.
PVC is put into high mixer, add stablizer, softening agent and other Synergist S-421 95 respectively and mediate at a high speed, drop into the plasticizing of twin screw plasticizing tablets press, pelletizing, cooling packing at 80～100 ℃.
The present invention is owing to the change to weighting agent; Thereby polyvinyl chloride cable material mechanical property and weathering resistance are greatly improved; Gained CABLE MATERIALS average index parameter: volume resistance: more than 3.2 * 1012 Ω .cm, embrittlement temperature-15 ℃, tensile strength>=15Mpa; Thermal ageing condition: 110 ± 2 ℃, 7 days (168 hours) the aging back strength retention ratio>=aging back of 75% (change rate of strength≤± 25%) elongation retention rate>=75% (elongation change rate≤± 25%); Thereby SE appliance plug material of the present invention, can be in certain filling-modified 6000 order ultrafine heavy calciums, can satisfy the quality index request for utilization.
Above example can select for use 6000 order ultrafine heavy calciums of different additions to reach the purpose that reduces production costs under the prerequisite that does not reduce performance index according to practical situation, can save the cost of 3-8% according to the product comparison of different additions and corresponding common weighting agent.
