Description
Technical field
The present invention relates to a kind of modified polypropylene material, particularly relate to a kind of electric motor car modified polypropylene material and preparation method thereof.
Background technology
1873, Englishman's Robert's Dai Weisen one-shot battery was used as power and has invented electric automobile, but does not list the affirming score of the world in. Generally acknowledge that first electric automobile was born in 1881 in the world, invention artificial France engineer Gustaf Te Lufu, this is one is the tricycle of power with lead-acid battery, occurs in that the electric motor car as electric power of NI-G, Ni-MH battery, lithium ion battery, fuel cell later successively.
Electric motor car in the market refers to the max. speed pure electric vehicle lower than 50 kilometers/hour, includes electric sightseeing vehicle, electric golf cart, electric patrol car, electric sanitation truck, electric transporting vehicle, electrically propelled traction vehicle, electronic engineering truck, mobility scooter for old people and extraordinary repacking electric motor car etc. Due to characteristics such as simple to operate, the broad view of electric motor car, practical, pollution-free, low energy consumption, increasingly it is widely applied to the regional place such as large-scale parks, scenic spot, closing community, villa quarter, holiday village, garden type hotel, city walking street at present.
Polypropylene (PP) is one of five big general-purpose plastics, and its yield is only second to PE and PVC and occupies the 3rd, is widely used in the fields such as automobile, Aero-Space, electronic apparatus, packaging, construction material and medical apparatus and instruments. Polypropylene abundance, cheap; Having good mechanical performance, electrical insulating property is good and the advantage such as stress crack resistant, and also has good chemical stability, and processing and forming easily, can be used for injecting, extrudes and the multiple method such as hollow molding, can make various products expeditiously. But polypropylene has the disadvantage in that the pending methyl group on l) building block reduces the pliability of chain, and spherocrystal granule is bigger so that it is brittle, and impact resistance is poor, high temperature rigid deficiency. 2) it is a kind of non-polar polymer, its dyeability, caking property, antistatic behaviour and all poor with inorganic phase capacitive. 3) machine-shaping shrinkage factor is big, and the dimensional stability of its goods is relatively low. 4) ageing-resistant degradation property is poor. These shortcomings limit the application of the polypropylene raw material as some target product (including injection grade, fibre-grade, film-grade etc.) or PP Pipe Compound. Accordingly, it would be desirable to improve its combination property, in order to it is carried out the exploitation of the degree of depth.
Additionally, the surface of polypropylene modified material is easy to, under the shock of foreign body (such as slungshot), partial fracture occurs, expose the mineral powder filled inside matrix, under slungshot clashes into, namely produce white point. And the surface of some parts of electric motor car is highly susceptible to the shock of slungshot in using environment, and electric motor car parts also usually inevitably collide with hard thing in transport and use procedure, and produce cut on surface thus affecting the outward appearance of product. Therefore how to improve the anti-slungshot impact of polypropylene material, anti-scratch performance also just causes increasing concern.
Additionally, owing to polypropylene material is non-polar material, surface can be low, make the poor compatibility of itself and most polymers, not easily infiltration, bonding and printing, paintability is poor, as when using in the electric motor car parts of paint spraying, will be low with the adhesion strength of paint because of it, and certain methods must be adopted to improve its polarity. It addition, for some electric motor car parts, it is sometimes desirable to carry out bonding with other materials, it is also desirable to polypropylene material has good adhesive property. Usual plastic part is in order to improve material surface tension, namely PASS is improved, before application, firstly the need of carrying out surface treatment, the dust greasy dirt of antistatic and absorption is eliminated by solvent, carry out surface modification with flame, corona discharge, surfactant, gas plasma etc., improve the polar group on surface, strengthen coating adhesion. This kind of technological difficulties be should be formed uniform surface, again can not overtreating, otherwise can cause the polymer chain scission on surface, thus the performance affected, the polarity therefore improving polypropylene material becomes an extremely attractive problem.
