Description
Technical field
The present invention relates to a kind of ABS resin material, particularly relate to a kind of nano modification ABS electric four-wheel vehicle and strengthen anti-aging PP Pipe Compound and preparation method thereof.
Background technology
1873, British Robert Dai Weisen primary cell was used as power and has invented electromobile, but did not list international affirming score in.Generally acknowledge that first electromobile was born in 1881 in the world, invent artificial French slip-stick artist's Gustaf Te Lufu, this is one is the tricycle of power with lead-acid cell, has occurred the power truck as electric power of NI-G, nickel metal hydride battery, lithium ion battery, fuel cell afterwards successively.
Four-wheel electric motor car in the market refers to that max. speed is lower than the pure electric vehicle of 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 power truck etc.Due to characteristics such as simple to operate, the broad view of four-wheel electric motor car, practical, pollution-free, less energy-consumption, be applied in large-scale parks, landscaped area at present more and more widely, closed the regional places such as community, villa quarter, holiday village, garden type hotel, city walking street.
ABS is one of important engineering plastics, is widely used in automotive industry, electrical instrumentation industry and mechanical industry etc.Often make the housing of gear, blade, bearing, handle, pipeline, meter housing, panel board, receiving set and televisor, safety helmet, sump liner, refrigerator liners etc.Also a lot of auto parts can be made, as mud guard, handrail etc.Plated item often makes Metal substitutes, as manufactured nameplate, decoration etc.Its foam material can replace timber to manufacture furniture and material of construction.ABS is that butadiene rubber particles is dispersed in " island " type structure in acrylonitrile styrene resin (AS) external phase, it is the example that the rigidity of resin and the elasticity of rubber combine, it not only has tough, hard, just balanced mutually excellent mechanical characteristic, and have that chemical proofing is good, good stability of the dimension, good, the easy application of surface luster and easy coloring advantage.
ABS is non-crystalline state, opaque resin, is generally light yellow granular or bead-like resin, and melt temperature is 217 ~ 237 DEG C, heat decomposition temperature >250 DEG C, and nonpoisonous and tasteless, water-intake rate is low.It has excellent physical-mechanical property, fabulous low-temperature impact resistance, electrical property, is easy to shaping and the feature such as mechanical workout.ABS is water-fast, inorganic salt, alkali and acids, is insoluble to most of alcohols and varsol, and is soluble in aldehyde, ketone, ester, and in some hydrochloric ether.
Although ABS has numerous advantages, due to the double bond produced containing divinyl, its weathering resistance is poor, and in easily aging, the variable color of outdoor long-term exposure, even chap, thus reduce shock strength and the toughness of material, flammable, heat-drawn wire is low.Thus be necessary to carry out modification to it, strengthen its shock strength, toughness and heat-drawn wire, to expand the range of application of material.
Along with the development of nanotechnology, applying nano compounding technology will provide new way and new approaches for the poly-new modified means of ABS of development.Research shows, all can have unusual or unusual characteristic, as surface-interface effect, small-size effect, quantum size effect and macro quanta tunnel effect etc. when any material enters nano-scale.These characteristics make nanoparticle structural expression go out unusual Wuli-Shili-Renli system approach, have the remarkable specific function such as light, power, electricity, heat, radiation, absorption.With inorganic nano material as Nano-meter CaCO3
3, ZnO, SiO
2, TiO
2, clay and ABS polymer carry out the advantage such as snappiness, workability of the existing macromolecular material of the nano combined nano composite material obtained, and has again the high rigidity of inorganic optical material, high-modulus, high mechanical property and good resistance toheat, low gas permeability and the absorptive character to UV-light such as mar-proof.
The polycrystal of the known single-phase or complex phase be made up of the crystal grain being of a size of 1-100nm is nanocrystalline material.Mostly the constitutional features of this type of material is that the atom on its crystal boundary accounts for more than 50% of crystal total atom number.Crystal boundary number in nanocrystal is 10
19individual crystal boundary/cm
3left and right.In the crystal boundary of enormous quantity or phase boundary, the atom at core position is subject to the restriction of adjacent dot matrix in necessarily arranging configuration, be different from the atomic arrangement in crystallographic grain, be different from non-crystalline state again, form a kind of new configuration, be the ordered structure of two dimension, have its oneself periodic law and interatomic distance, different crystal boundary is different again each other.At 1cm
3in nanocrystal 10
19individual crystal boundary occurs 10
19individual atomic configuration, because the orientation of each crystal grain is different, the restraint force size and Orientation that the atom of crystal grain to periphery crystal boundary core place of different orientation acts on is different, thus causes atomic arrangement configuration inequality.The specific arrangement of the atom in crystal boundary or phase boundary; In crystal boundary or phase boundary, namely the new configuration of core part of atoms arrangement is cause the nanocrystalline root occurring new capability.The structural singularity of nano crystal material makes it have many traditional coarse-grains, the unrivaled excellent properties of nano amorphous material.
Average grain size is one of important structure parameter of nano crystal material, this is because the most important constitutional features of nano crystal material is its high interphase density, and average grain size can its interface content of direct reaction.Therefore, material impact can be produced to composite property by controlling nano crystal material grain size, form and distribution.
