Abstract
The invention relates to a special ultrafine powder filled and modified material for polyvinyl chloride (PVC) outdoor profile in the technical field of high-molecular materials. The special ultrafine powder filled and modified material for the PVC outdoor profile is prepared by adopting multiple raw materials such as PVC, plasticizer, stabilizer, processing additive, modifier, 6000-mesh heavy calcium carbonate and the like. The preparation method comprises the following steps of preparing PVC mixture by adequately and uniformly mixing all raw materials and auxiliary materials through a high mixing machine, and extruding the PVC mixture to be granulated through an extruder to obtain the special ultrafine powder filled and modified material for the PVC outdoor profile. The special ultrafine powder filled and modified material for the PVC outdoor profile is high in dispersion property and compatibility, the mobility and processability of the system can be improved, good physical mechanical property and aging property can be obtained, and the cost of the product can be reduced.
Description
Technical field
The present invention relates to a kind of filling-modified outdoor plastic-steel section bar PP Pipe Compound of superfine powder of polymeric material field.Be specifically related to the filling-modified of polyvinyl chloride.
Background technology
Traditional outdoor plastic-steel section bar often uses ordinary calcium carbonate (800 orders are following), and very poor with resin matrix consistency, addition is limited, and the performance of product is had to many detrimentally affects.
The object of the invention is to overcome the compound of common inorganic particulate and organic substance, the shortcoming existing in processing preparation process.While use in superpolymer due to common calcium carbonate, easily cause the boundary defect of bi-material, fill a certain amount of superfine powder, make it become functional filler by general weighting agent, eliminate and in organism, disperseed inequality, the boundary defect that filler and matrix exist, improve the mechanical property of composite product, better strengthened toughening effect thereby product is obtained.
Summary of the invention
The outdoor plastic-steel section bar material of the filling-modified polyvinyl chloride of modification 6000 order ultrafine heavy calcium, in following ratio proportioning:
90～110 parts of PVC;
3～30 parts of superfine powders;
1.5～5 parts of organic tin stablizers;
0.5～4.5 part of modifier;
Softening agent 1-3 part;
0.2～2 part of surface treatment agent;
0.3～1.2 part of internal lubricant;
0.4～1.5 part of external lubricant.
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%, after allocating into, can improve weathering resistance.
The advantage that the present invention compared with prior art has is: when common weighting agent is filled into certain proportion, can not meet the physicals requirement of its product completely, but when adding after a certain amount of modification 6000 order ultrafine heavy calciums, its property indices all can meet quality index requirement, in addition, also reduce cost and its relevant performance index increase, and cost is declined to some extent.
The component of the present invention using the 6000 order ultrafine heavy calciums of the particle diameter≤2 μ m of surface treatment agent and 90% as outdoor plastic-steel section bar of filling-modified polyvinyl chloride and preparation method thereof, the improved technique of taking to dehumidify, the inorganic material powder adding is changed to Organic by inorganic nature, by surface hydrophilic oleophobic property, when changing lipophilic-hydrophobic property into and successfully having solved 6000 order ultrafine heavy calciums interpolation, the problem of chestnut reunion and poor dispersion, has improved intermiscibility, dispersiveness, mobility and processing characteristics after powder and mixed with resin.
The present invention is ensureing that under the prerequisite of plastics performance, 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.
The present invention is described in further detail by following examples, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
Embodiment: outdoor plastic-steel section bar composition and the weight of superfine powder modification are:
PVC 120kg
Stablizer (commercially available organotin stabilizer) 5kg
Modifier (commercially available ACR-401 or polyacrylate(s) material) 3.3kg
Softening agent (DOP or ESO) 2.5kg
Internal lubricant (autogamy) 0.35kg
Paraffin (WAX) 0.44kg
Titanium dioxide (TiO2) 2kg
Whitening agent (commercially available) 0.05kg
6000 order water-ground limestone 26kg
Surface treatment agent (autogamy) 0.68kg
Its preparation method is:
6000 order ultrafine heavy calciums are put into high mixer, high-speed stirring starts dehumidifier while being mixed into 120 ~ 180 DEG C of temperature, and temperature reaches 100 ~ 110 DEG C and adds phthalate and paraffin, mix and blend 5 ~ 8 minutes, then put into DEG C discharging of cold mixer temperature to 30 ~ 50, be modification 6000 order ultrafine heavy calciums.
PVC is put into high mixer, add respectively stablizer, softening agent and other Synergist S-421 95 at 80～100 DEG C of high-speed kneadings, drop into the plasticizing of twin screw plasticizing tablets press, pelletizing, cooling packing.
The present invention is due to the change to weighting agent, thereby polyvinyl chloride mechanical property and weathering resistance are greatly improved, gained pellet average index parameter:, above, the tensile strength >=15Mpa in embrittlement temperature-15 DEG C, thermal ageing condition: 110 ± 2 DEG C, 7 days (168 hours) aging rear strength retention ratio >=75%(change rate of strength≤± 25%) aging rear elongation retention rate >=75%(elongation change rate≤± 25%), thereby the outdoor plastic-steel section bar material of the present invention, can be in certain filling-modified 6000 order ultrafine heavy calciums, can meet quality index service requirements.
Above example can select according to practical situation 6000 order ultrafine heavy calciums of Different adding amount to reach the object reducing production costs under the prerequisite that does not reduce performance index, can save the cost of 3-8% according to the product comparison of different additions and corresponding common weighting agent.
