Description
Technical field
A kind of activeness and quietness PVC composition and preparation method thereof, belongs to technical field of plastic.
Background technology
Although PVC material intensity is higher but generally there is the problem that fragility is bigger, have impact on its application.For compensating its defect, in formula, generally add the toughener such as CPE, MBS, ACR, ABS, ASA the toughness of PVC material is greatly improved, but the use of toughener can reduce the intensity of material, vicat softening temperature.For solving this problem, the nanometer particles such as rigid particles such as nano imvite, nano-calcium carbonate, inorganic compound whisker, glass fibre, carbon fiber, CNT are applied in PVC material, but owing to nanometer particle is easily reunited, there is again poor dispersion and the problem of interface cohesion difference when polymer is blended, thus have impact on the activeness and quietness of PVC material.
CN 104231488A discloses a kind of activeness and quietness PVC and preparation method thereof, the PVC of the activeness and quietness of this invention is made up of the raw material of following parts by weight: polyvinyl chloride resin 100 parts, precipitated calcium carbonate 8 ~ 9 parts, calcium-zinc composite stabilizing agent 2 ~ 4 parts, MBS LB-156 impact modifier 6 ~ 8 parts, LP-90 processing aid 0.8 ~ 1.2 part, lubricant 0.75 ~ 1.1 part, titanium dioxide 1 ~ 2 part.The tensile yield strength of made activeness and quietness PVC is 12.8 ~ 14.3MPa, and impact strength is 13.5 ~ 14.9kJ/m2, elongation at break is 87 ~ 93%.This invention is modified by adding MBS LB-156 impact modifier and LP-90 processing aid, and its hot strength receives considerable influence.The activeness and quietness of PVC to be realized in prior art, need to add reinforcing agent and toughener simultaneously, but there will be the problem that intensity declines.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that a kind of activeness and quietness PVC composition with higher-strength and high tenacity and preparation method thereof, to solve to occur, when general PVC is toughness reinforcing, the problem that intensity declines.
The technical solution adopted for the present invention to solve the technical problems is: this activeness and quietness PVC composition, it is characterized in that, weight portion consists of: polyvinyl chloride resin 100 parts, organic tin stabilizer 1.5 ~ 2.5 parts, PVC/ surfactant enveloped carbon nanometer tube 4 ~ 8 parts, processing aid ACR1.5 ~ 2.5 part, lubricant 1.0 ~ 1.5 parts, titanium dioxide 1.5 ~ 2.5 parts, fine calcium carbonate 7 ~ 12 parts.
Present invention CNT improves intensity and the toughness of PVC, CNT utilizes PVC to be coated with simultaneously, strengthen the affinity of CNT and polyvinyl chloride resin, to solve CNT poor dispersion and the poor problem of interface cohesion when being blended with PVC, prevent the agglomeration of CNT, it is ensured that the CNT activeness and quietness effect to compositions.
Preferably, described polyvinyl chloride resin be average degree of polymerization be the polyvinyl chloride resin of 800 ~ 1200.Polyvinyl chloride resin be average degree of polymerization be to affect one of key factor that PVC composition is blended, because the gap between polyvinyl chloride resin macromole directly affects polyvinyl chloride resin and the compatibility of CNT and dispersibility, the PVC/ surfactant enveloped carbon nanometer tube of the present invention polyvinyl chloride resin be average degree of polymerization be 800 ~ 1200 time be combined with polyvinyl chloride resin the most firmly, dispersion the most uniform, the strongest toughening effect is the most obvious.
Preferably, the described Surface coating that PVC/ surfactant enveloped carbon nanometer tube is CNT have one layer of PVC and a surfactant 1000:2 ~ 15 mix in mass ratio after the film of composition.Surfactant mainly affects PVC being uniformly distributed in carbon nano tube surface, reduces the cohesive energy of CNT, makes PVC in PVC/ surfactant enveloped carbon nanometer tube be combined evenly with CNT, the highest with the affinity of polyvinyl chloride resin.
Preferably, described surfactant is the one in quaternary ammonium salt, amine salt, phosphate, sulfonate, polyhydric alcohol, polyol fatty acid ester, polyethylene glycol oxide and derivant thereof, quatemay ammonium inner salt, alanine type surfactant, two or more the compound of arbitrary proportion.The selecting of surfactant is as the criterion can reduce the cohesive energy of CNT, and can be the most affine with PVC.
Preferably, described surfactant is glycerol partial fatty acid ester.Glycerol partial fatty acid ester is a kind of preferably polyol fatty acid ester class surfactant, the cohesive energy of elimination CNT that can be best, make CNT fully dispersed in oxolane, the PVC being dissolved in oxolane is made more uniformly to be coated on carbon nano tube surface after oxolane is extracted, and appropriate glycerol partial fatty acid ester can be retained in the PVC film of parcel, when beneficially compositions is blended, CNT is dispersed.
Preferably, described titanium dioxide is Rutile type titanium dioxide.
The preparation method of a kind of above-mentioned activeness and quietness PVC composition, it is characterised in that preparation technology is:
1) the most molten: PVC is dissolved in oxolane, then in oxolane, add surfactant and CNT, after stirring, after being stripped oxolane reclaiming, obtain enveloped carbon nanometer tube group；
2) pulverize: enveloped carbon nanometer tube group is carried out attrition grinding, obtains enveloped carbon nanometer tube；
3) it is blended: composition polyvinyl chloride resin 100 parts by weight, organic tin stabilizer 1.5 ~ 2.5 parts, step 2) enveloped carbon nanometer tube 4 ~ 8 parts prepared, processing aid ACR1.5 ~ 2.5 part, lubricant 1.0 ~ 1.5 parts, titanium dioxide 1.5 ~ 2.5 parts, fine calcium carbonate 7 ~ 12 parts weighs material, puts into mixer and rear discharging is blended and get final product.
The present invention adds the CNT being coated with the coating film that PVC and surfactant are formed through the most molten, extracting in PVC composition, allow to increase the CNT of PVC intensity and toughness good be dispersed in PVC composition, prepare a kind of performance more preferable activeness and quietness PVC.
Preferably, described step 1) is the most molten specifically comprises the processes of: be dissolved in oxolane by PVC, PVC is 1:5 ~ 10 with the mass ratio of oxolane, surfactant and CNT is added again in oxolane, surfactant addition is the 2% ~ 5% of carbon nanotube mass, the addition of CNT is the 10% ~ 30% of PVC mass, after stirring 20 ~ 40min, obtains the CNT of PVC/ surfactant cladding to oxolane after being stripped reclaiming.
The CNT that the present invention selects, compared with other nanometer particle, can reach more preferable activeness and quietness effect in PVC composition.But owing to CNT exists higher cohesive energy, and can not simply be coated with as other nanometer particle or directly add.PVC first will be dissolved in oxolane in preparation technology by the present invention, adds surfactant and CNT, and the surfactant added can reduce the cohesive energy of CNT, enables CNT to be homogeneously dispersed in the tetrahydrofuran solution of PVC.So, PVC molecule be easily advanced into the surface of CNT formed comprehensive, be coated with uniformly.After being stripped oxolane reclaiming, the surface of CNT defines one layer of complete PVC/ Surfactant Films.CNT after being wrapped by is uniformly dispersed in PVC, and the compatibility with PVC base is good, can realize the enhancing to PVC material and toughness reinforcing simultaneously.The addition of surfactant needs to eliminate as far as possible the cohesive energy of CNT, and don't can excess be retained in the performance affecting PVC composition in PVC coating film.The relative quantity of PVC and CNT determines the thickness of PVC coating film and the volume of the enveloped carbon nanometer tube of formation, and this volume not only molecular gap with selected polyvinyl chloride resin adapts, and dispersion efficiency when being also blended with each component adapts.
Preferably, described PVC is 1:7 ~ 8 with the mass ratio of oxolane, and surfactant addition is the 2% of carbon nanotube mass, and the addition of CNT is the 25% of PVC mass.Optimal PVC activeness and quietness effect can be reached under this proportions,
