Description
Technical field
The present invention relates to polypropylene field, furtherly, relate to a kind of tri compound nucleator and the application in preparation Reinforced Polypropylene thereof.
Background technology
Polypropylene is a kind of thermoplastics be widely used, and cheap and over-all properties is better, can improve mechanical property and the optical property of polypropylene articles further, realizing polypropylene high performance by adding nucleator.Polyacrylic nucleator be a class for improving crystalling propylene behavior, thus improve the auxiliary agent of its physical and mechanical properties and thermomechanical property.Nucleator is divided into mineral-type, glucitols, phosphoric acid salt, rosin based and high score subclass nucleator.
At present, on market, widely used polypropylene nucleater is organic nucleating agent, as NA11 [2,2 '-ylidene methyl-two (4,6-di-n-butyl phenol) sodium phosphate], NA-2l [methylene-bis (2,4-di-tert-butyl-phenyl) aluminum phosphate] etc.Organic nucleating agent consumption is few, and nucleating effect is obvious, can improve polyacrylic Tc, good stability, increase just effective, can significantly improve polyacrylic heat-drawn wire and mechanical property, but this type of nucleator price be higher.
Sodium Benzoate, molecular formula is C
6h
5cO
2na is benzoic sodium salt.Sodium Benzoate, as decentralized nucleator, can improve polyacrylic Tc, shortens crystallization time; Under high pressure shaping, polyacrylic crystal formation can also be changed.Sodium benzoate nucleator, compared with other nucleators, has that synthesis technique is simple, cost is low, an advantage such as nontoxic, easy storage.
Inorganic particulate also has nucleator effect, but nucleation efficiencies is general.Molecular sieve is a kind of material being different from other inorganic particulates, has uniform micro, and its aperture is suitable with general molecular size, is by SiO
2, Al
2o
3with the inorganic microporous material that basic metal or alkaline-earth metal form, its chemical constitution formula is typically expressed as: MxAl
2o
3ySiO
2zH
2o(M=K, Na, Ca, Mg).Traditional molecular sieve is that a class has uniform pore size, huge internal surface area and pore volume, has again a class crystalline microporous material of the characteristics such as ion exchangeable simultaneously, utilize this uniform aperture differing molecular can be sieved by diameter, be therefore called as molecular sieve.According to molecular sieve pore passage arrangement and the ordery analysis of skeletal atom, molecular sieve can be classified as two large classes, and the first kind is crystalline microporous material, as traditional zeolite, AlPO
4molecular sieves etc., it has regular duct arrangement and skeletal atom order, and its pore diameter range is 0.3 ~ 1.2 nanometer.The mesoporous materials such as MCM-41, SBA-15 that Equations of The Second Kind has found since being the nineties, its aperture size is evenly distributed, pore diameter range is that 2 ~ 50 nanometers are adjustable, duct arrangement is in order regular, but the atomic arrangement forming its skeleton is unordered, as amorphous silicon [Xiangling Ji, J Eric Hampsey, Qingyuan Hu.Mesoporous Silica-ReinforcedPolymer Nanocomposites [J] .Chem.Mater., 2003,15:3656-3662].
Wherein mesoporous material SBA-15 is orderly hexagonal phase mesoporous silica molecular sieve.Mesoporous molecular sieve SBA-15 specific surface is large, has homogeneous channel diameter distribution, and aperture can modulation, wall thickness and hydrothermal stability very high, so SBA-15 has wide practical use in fields such as catalysis, separation, biology and nano materials.
Mesoporous silica MCM 41 is a kind of novel nano structural material, has the features such as duct is six side's ordered arrangement, size is even, aperture can regulate continuously within the scope of 2-10nm, specific surface area is large.
Wang Na [Wang Na in 2006, wear bright cloud, Fu Luxiang. mesoporous nano MCM-1 weighting material is on the impact [J] of behavior of polypropylene composites performance. material engineering, 2006, supplementary issue 1:143-146] etc. research finds, for MCM-41, no matter be of a size of granulated particle or the long strip shape particle of 20 ~ 40nm, when loading level is suitable, all have polypropylene and significantly strengthen and toughness reinforcing effect, the thermotolerance of compound system is also improved.
Polypropylene nucleater is that one is used for changing PP crystallization behavior, thus changes its crystal habit, finally improves the auxiliary agent of its physical and mechanical properties and thermomechanical property.In recent years, for giving full play to the advantage of all kinds of nucleator, research is had to start to focus on the different nucleator of research or the synergistic effect between nucleator and other auxiliary agents.Hongwei Bai(Journal of Applied Polymer Science, Vol.111,1624 – 1637 (2009)) have studied α nucleator (DMDBS) and the composite rear impact on crystalling propylene behavior of beta nucleater (TMB-5) two kinds of nucleators, finding that the nucleator of different ratios proportioning can make polypropylene obtain these two kinds of Crystal types of different ratios, providing a kind of by changing nucleator kind and the polyacrylic research method of ratio acquisition different performance.
At present, the nucleation efficiencies of organic nucleating agent is higher, but price is more expensive, and the price of inorganic nucleator is relatively cheap, but nucleation efficiencies is lower.Several nucleator is simply combined and might not obtain desirable nucleating effect.

Table 2
As shown in table 2, adopt and add organic nucleating agent and the blended composite assistant of mesoporous material can make crystalling propylene performance have more obvious raising simultaneously, mechanical property is also improved more.Such as add the comparative example 2 of 0.1 portion of NA11 nucleator, degree of crystallinity is 42.6%, comparative example 5 degree of crystallinity adding 0.1 portion of NA11/SB nucleator is 44.9%, and the comparative example 8 that NA11 and mesoporous material add simultaneously, degree of crystallinity is 44.4%, when composite nucleating agent both comprised NA11/SB in embodiment 1, comprise mesoporous material SBA-15 again, the degree of crystallinity of material is increased to 45.1%.Same when adding number and being 0.2 part, the degree of crystallinity of embodiment 2 is higher than other polypropylene with content, and wherein embodiment 2 is 47.2%, and comparative example 3 and comparative example 6 are respectively 44.2% and 42.9%, and comparative example 9 is 45.1%.So adopt the method for ternary built, can synergistic effects be produced, the degree of crystallinity of material is improved.
From table 2, the result of mechanical property is found out, identical with the trend of degree of crystallinity, and the nucleator of tri compound can obtain the highest polypropylene material of bending elastic modulus.In the comparative example 1 of pure PP, the bending elastic modulus of material is 0.885GPa, after with the addition of nucleant agent N A11 or binary nucleant agent N A11/SB, the bending elastic modulus of material is all improved, and is 1.10 ~ 1.13GPa, and increase rate scope is 24.3% ~ 27.7%, and after adopting interpolation ternary nucleant agent N A11/SB/SBA-15, the modulus in flexure of material improves further, reaches the 1.17GPa of the embodiment 1 and 1.19GPa of embodiment 2, compares pure sample increase rate and be respectively 32.2% and 34.5%.Determine amount of deflection modulus in flexure and also present identical trend, ternary nucleator add-on be 0.1 part and 0.2 part time, embodiment 1 and embodiment 2 can obtain the stress in bending of 28.6MPa and 29.1MPa respectively, all higher than NA11, binary nucleant agent N A11/SB, binary nucleant agent N A11/SBA-15, illustrate that tertiary blending can obtain synergistic effect.
Therefore, the ternary nucleator that the data declaration of table 2 adds mesoporous material composite with organic nucleating agent improves more obvious than the over-all properties directly adding two kinds of Nucleating Agent on Pps, the particularly degree of crystallinity of material, bending elastic modulus is all significantly improved, illustrate that ternary nucleator can produce synergistic effect, therefore, tri compound nucleator composite polypropylene of the present invention is the polypropylene material of excellent property.
