Abstract
The invention provides flame-retarded ABS material which is specially used on a casing of a lead-acid storage battery, whose residuals are mainly formed by the following components except for ABS, flame retardant, synergistic agent, flame retardant agent toughening agent and compatibilizer, wherein the flame retardant adopts decabromodiphenyl oxide whose weight is 10%-15% of whole weight, the synergistic agent adopts antimony oxide whose weight is 3%-5% of the whole weight, the flame retardant agent adopts fluoric macromolecule material whose weight is 0.1%-0.5% of the whole weight, the toughening agent adopts graft copolymer of PB whose weight is 0%-5% of the whole weight, and the compatibilizer adopts ABS graft maleic anhydride whose weight is 0%-5% of the whole weight. The flame-retarded ABS material endows the properties of higher impact strength, brighter appearance, non flame retardant precipitation, excellent hot sealing and bonding property with glue for a valve-controlled lead-acid storage battery, and effectively prevents the leakage of sulfuric acid. And the higher flexural modulus can avoid or reduce the ballooning phenomenon under extreme conditions.
Description
Technical field
The present invention relates to special-purpose anti-flaming ABS material for lead-acid storage battery outer case.
Background technology
The analysing valve control type lead-acid accumulator battery shell, requiring has higher shock resistance, and shell will bear ball falling impact; Be assembled into the bump that falls that can bear battery behind the battery.Combining between the battery jar of analysing valve control type lead-acid accumulator battery and the lid by the sealing of heat seal and glue, require sheating material that the heat seal performance can be arranged preferably and adhesiveproperties is preferably arranged with glue, be that the sulfuric acid of 1.2-1.4g/ml contacts the use properties that does not influence material with density for a long time, product surface can not be separated out material.Flame-proof ABS in the market generally all be the high material of thermal denaturation temperature, but shock resistance does not reach the requirement of lead-acid storage battery outer case material; The material that impact property is good, thermal denaturation temperature do not reach requirement again.And the fire retardant in the flame-proof ABS makes product appearance bad from the phenomenon of material internal to the outside migration in addition.Experiment shows, the index such as tensile strength, flexural strength, shock strength, thermal denaturation temperature that is applied to the lead-acid storage battery outer case anti-flaming ABS material is a mutual restriction.
Summary of the invention
Technical problem to be solved by this invention provides the good special-purpose anti-flaming ABS material for lead-acid storage battery outer case of a kind of shock resistance.For this reason, the present invention by the following technical solutions: it is except that ABS, and surplus is mainly composed of the following components: fire retardant, synergist, flame retardant, toughner, compatilizer are formed; Wherein, fire retardant adopts decabromodiphynly oxide, and its weight accounts for the 10%--15% of gross weight; Synergist adopts antimonous oxide, and its weight accounts for the 3%--5% of gross weight; Flame retardant adopts fluorine-containing macromolecular material, and its weight accounts for the 0.1%--0.5% of gross weight; Toughner adopts the graft copolymer of PB, and its weight accounts for the 0%--5% of gross weight; Compatilizer adopts the ABS grafted maleic anhydride, and its weight accounts for the 0%--5% of gross weight.
ABS is acrylonitrile-butadiene-styrene resin, acrylonitrile-butadiene-styrene resin.
Owing to adopt technical scheme of the present invention, given the analysing valve control type lead-acid accumulator battery shell higher resistance to impact shock, outward appearance light, no fire retardant is separated out; Good heat seal performance and with the adhesiveproperties of glue, prevented the vitriolic leakage effectively; Battery bulging phenomenon under extreme conditions can be avoided or reduce to higher modulus in flexure.
Embodiment
Following table is the component except that ABS of embodiment 1-9 and the per-cent that accounts for gross weight thereof, wherein, fire retardant adopts decabromodiphynly oxide, synergist adopts antimonous oxide, flame retardant adopts fluorine-containing macromolecular material, toughner adopts the graft copolymer of PB (polyhutadiene), and compatilizer adopts the ABS grafted maleic anhydride.
In the preparation, ABS base-material, fire retardant, synergist, flame retardant, toughner, compatilizer, processing aid etc. are mixed according to adding in the high-speed mixer.Use the twin screw extruder granulation, extruder temperature is controlled at 180 ℃--in 215 ℃ of scopes.Therein, the adding of processing aid is the convenience in order to process mainly, and whether it adds the performance that does not influence the finished product.Processing aid is antioxidant (1010 and 168) and dispersion agent (EBS)
