Description
Technical field
The application belongs to nano plastic Material Field, relates in particular to a kind of PP nano plastic and preparation method thereof.
Background technology
Nanomaterial science is a complete brand-new scientific domain of just having risen in recent years, and it relates to the multi-field knowledge such as state of aggregation physics, chemistry, material, biology. The core content of " nanometer technology " is the agglomeration traits that how to solve nano particle, because nano particle itself is very easily reunited, the nano particle that obtains single dispersion is very difficult, and how to make nano particle be distributed to equably going in matrix is the key technology of " nanometer technology ".
From the application study report of " nanometer technology ", analyze at present, the method that can carry out industrialization has two kinds: 1, nano intercalatedization technology, by the n-MMT of intercalation processing, make certain compaction rate, the master batch of size uniform, again this master batch process is mixed and stirred to blend and granulation, solve nano material and in matrix, disperse an inhomogeneous difficult problem, make nano composite material. 2, utilize vibromill dispersion method can make nano particle dispersed in matrix, substantially do not produce reunion, really accomplished nanoscale dispersion.
" nano plastic " refers to that matrix is high molecular polymer, and the abundant dispersion by nano particle in plastic resin has improved the performance such as heat-resisting, weather-proof, wear-resisting of plastics effectively. " nano plastic " can make common plastics have rigidity and the heat resistance as the ceramic material, retained again toughness, resistance to impact and workability that plastics itself possess simultaneously. At present, can carry out having by nanometer particle-modified NPE, NPET and NPA6 (being nano-polyethylene, nanometer PET polyester, nano-nylon 6) of industrialization and utilize nano particle, silver (Ag+) is designed in the micropore of particle surface and stable, just can make nanometer and plant silver-colored anti-biotic material, this material is joined in plastics and goes just to make plastics have antibacterial and mouldproof, the self-cleaning premium properties that waits, becomes Green Product. At present, in ABS, SPP, HIPS, PP plastics, be applied.
" nano plastic " is a kind of high-tech new material; there is good development prospect; due to domestic, this new material is also lacked to understanding; there is no complete quality certification system and tight production management, be in the situation that one " is jumped on the bandwagon ", mix the genuine with the fictitious; true and false difficulty is debated; make " nano plastic " just face at the beginning the danger of " dying young ", so the author urgently wishes that national departments concerned can protect this new material by corresponding standard and statute, promote growing up healthy and sound of it.
" nanometer " is the measurement unit of a length, and its yardstick is 1/1000000000th meter (10-9m). In general, nano material refers in two-phase microstructure and has at least the unidimensional scale of a phase to reach nanoscale. Nano particle diameter is very little, and surface can be very large, very easily reunites, so how preparing nano particle itself is exactly a very complicated technical problem. The nano particle that at present can make and utilize mostly is inorganic nano-particle, and the nano particle that can be effectively plastics be carried out to modification is SiO2, TiO2, CaCO3, and illiteracy is opened up soil (MMT) etc. And universal along with humanity concept, and the formation of novel harmonious society, design high, impact-resistant PP nano plastic of a kind of intensity and preparation method thereof and be very important.
The same side that methyl is arranged in molecular backbone claims isotactic polypropylene, if the chaotic both sides that are arranged in molecular backbone of methyl claim random polypropylene, the both sides that are arranged alternately in molecular backbone when methyl claim syndiotactic polypropylene. In the acrylic resin that general industry is produced, isotactic structural content is about 95%, and all the other are random or syndiotactic polypropylene. Industrial products are taking isotactic thing as main component. Polypropylene is also including the copolymer of propylene and a small amount of ethene. Be generally translucent colorless solid, odorless is nontoxic. The highly crystalline due to compound with regular structure, therefore fusing point can be up to 167 DEG C. Heat-resisting, corrosion-resistant, the sterilization of goods used vapour is its outstanding advantages. Density is little, is the lightest general-purpose plastics. Shortcoming is that low-temperature impact resistance is poor, more aging, but can be overcome by modification respectively.
The PP material of copolymer type has lower heat distortion temperature (100 DEG C), low transparency, low-luster, low rigidity, but has stronger impact strength, and the impact strength of PP increases along with the increase of ethylene contents. The vicat softening temperature of PP is 150 DEG C. Because degree of crystallinity is higher, surperficial rigidity and the anti-scratch characteristic of this material are fine. There is not ESC problem in PP.
