Description
Technical field
The present invention relates to a kind of new-energy automobile battery cell case material.
Background technology
Popularization and application along with new-energy automobile, accumulator, especially the technical development of lead battery also increasingly comes into one's own, general battery cell case PP Pipe Compound, it mostly is the middle and high anti-impact injection grade PP Pipe Compound that polypropylene plant is directly produced, as more domestic battery cell case factory adopts import material Singapore polyolefin A Y564, B3001 to do battery cell case, it is relatively costly. Thus mode that more domestic universities and colleges, scientific research institution adopt small-entity polypropylene and toughness reinforcing body blended is modified with substituting import one material; reduce cost to a certain extent; but there is also that quality is unstable, fluctuate excessive defect, production process is loaded down with trivial details, can not the shortcoming such as large-scale production.
New forms of energy battery case is when design, require to have stronger fire-retardant, corrosion-resistant, shock-resistant, anti-vibration, anti-extrusion, the resistance to mechanical performance such as jolt, take into account the performance of antioxidation (UV resistant) simultaneously, weatherability (resistance to atmospheric corrosion, not easily it is corroded), thus ensureing that it has stronger serviceability, being adapted on automobile, especially new-energy automobile using.
Summary of the invention
Present invention aim at providing a kind of new-energy automobile battery cell case material, the battery cell case that this casing material produces is used to have good thermal stability and antioxidation, corrosion resistant chemical property, simultaneously, also have mechanical performance shock-resistant, antidetonation concurrently, and then strengthen the service life of battery cell case, thus reducing its use cost, for the use technical support that the use offer of new-energy automobile is good.
The scheme of invention is as follows: new-energy automobile battery cell case material, is made up of following raw material:

Further, it is made up of following raw material:
ABS resin 95 parts, 16 parts of modified polyphenyl alkene, disodium hydrogen phosphate 7 parts, IPPP 8 parts, APTES 16 parts, Hydroxypropyl acrylate 7 parts, three (1, the chloro-2-propyl group of 3-bis-) phosphate 4.5 parts, Firebrake ZB 2 parts, magnesium oxide 11 parts, white carbon black 0.9 part, 4,4'-dioctyl diphenylamine 0.8 part, Aronix M 240 4 parts, 4-amino-5-hydroxyl naphthalene-2,7-disulfonic acid sodium salt 0.3 part.
Further, described modified polyphenyl alkene includes the following material counted by weight percentage: impact polypropylene 76-82%, atactic copolymerized polypropene 8-10%, Alathon 6-16%; As raw material, adding percentage by weight at pelletization stage is 0.15-0.51% beta crystal-type nucleater; Adding percentage by weight in mix stages is the antiager of 0.1-0.5%.
Further, being the politef of 0.01-0.03% including at least weight ratio in described antiager, described antiager is zinc oxide or dilauryl thiodipropionate or white carbon black.
Further, modified polypropene preparation method, comprise the steps:
S1, alpha-crystal form polypropylene synthesizes, after completing according to following weight percentage ratio dispensing: impact polypropylene 76-82%, atactic copolymerized polypropene 9-10% and Alathon 6-16%, adding percentage by weight is the antioxidant of 0.2-0.35%, under the hot environment of 200-220 ° of C, be that 0.31-0.4g/min carries out being mixed to get mass fraction according to melt index it is 6-10% alpha-crystal form polypropylene.
S2, crystal formation is changed, and the alpha-crystal form polypropylene obtained in step S1 is raw material, adds 0.15-0.51% beta crystal-type nucleater in pelletization stage is to it; Two kinds of raw materials mix 3-5min, extruding pelletization in double screw extruder in high-speed mixer, and barrel temperature is 150 DEG C-210 DEG C, and screw speed is 300-400rpm, obtains alpha-crystal form polypropylene and Beta-crystalline polyacrylic mixture;
S3, mix stages, adds politef and all the other antiagers 0.1-0.5% of 0.01-0.03% in it.
Further, the alpha-crystal form polypropylene in step S2 is 70:30 to 80:20 with the weight ratio of Beta-crystalline polyacrylic.
Further, in the mix stages of described step S3, also include step S4, within it add auxiliary agent, described auxiliary agent include the one in mica powder, blanc fixe, graphite, molybdenum bisuphide or several; The weight percent content of the auxiliary agent added is 0.5-1.2%.
The present invention, rational proportion by each formula so that the battery cell case that this casing material produces has good thermal stability and antioxidation, corrosion resistant chemical property, simultaneously, also have mechanical performance shock-resistant, antidetonation concurrently, and then strengthen the service life of battery cell case.
Particularly by increasing modified polypropene formula, adopting the mass fraction of ethylene that impact polypropylene, atactic copolymerized polypropene and Alathon are polymerized is 6-10% alpha-crystal form polypropylene, take full advantage of impact polypropylene and there is comparatively superior toughness, the superior chemical stability of atactic copolymerized polypropene and decay resistance, obtain the alpha-crystal form polypropylene type that mass fraction is 6-10%, its crystallization degree is high, and impact resistance and decay resistance are stronger, but its shrinkage factor is relatively big, is 1% ~ 2.5%. so the application is on its basis, with it for raw material, adding percentage by weight at pelletization stage is 0.15-0.51% beta crystal-type nucleater, make it melt, obtain alpha-crystal form polypropylene and Beta-crystalline polyacrylic mixture, the crystalline state taking full advantage of Beta-crystalline polyacrylic is different with the crystalline state of alpha-crystal form polypropylene, its crystallization is spherical, and there is no boundary clearly between its spheroidal cementite, it can produce micropore when being subject to force-extension or impact, it can fully absorb impact energy, and slow down deformation, there is stronger toughness simultaneously, but decay resistance obtains certain slowing down.So after the synthesis of this modified polypropene, within it adding again percentage by weight is antiager 0.1-0.5%, finally ensure that it has stronger mechanical performance, decay resistance and good chemical stability.
