Description
Technical field
The present invention relates to battery case technical fields, more particularly to a kind of flame-proof battery case and preparation method thereof.
Background technique
Currently, people are to automobile component with the development of automobile industry and the enhancing of people's awareness of safety, environmental consciousness
Characteristic requirements dramatically increase, and secondary battery jar is even more indispensable, and people require it more stringent, secondary battery jar material need
The characteristic for having high temperature resistant, high fire-retardance, high intensity, lightweight, high in environmental protection, wherein the high flame retardant of traditional storage battery cabinet
It can be generally unable to reach comparatively ideal effect, when burst accident occurs, often cause personnel escape's time short because anti-flammability is bad,
In the presence of very big security risk.
Summary of the invention
The technical problem to be solved by the present invention is to how improve the flame retardant property of Battery case.
In order to solve the above technical problems, the present invention provides a kind of flame-proof battery case, including cabinet, the chemical content of cabinet
And parts by weight are as follows: polyvinyl chloride resin: 9-11 parts, dimer (fatty acid) yl: and 5-7 parts, the poly- phthalimide copolymer of organosilicon one: 3-5 parts,
Decabromodiphenylethane: 4-6 parts, molybdenum trioxide: 2-4 parts, polyester fiber: 2-3 parts, alumina silicate fibre: 4-5 parts, graphene oxide:
4-6 parts, aluminium powder: 2-4 parts, TiO2: 1-2 parts, SiO2: 2-3 parts, Cr2O3: 1-2 parts, rare earth: 5-7 parts.
Technical effect: the cabinet in the present invention, as base-material, has certain tensile strength by polyvinyl chloride resin after solidifying,
It may insure that the intensity of Battery case, the decabromodiphenylethane of addition are one kind of fire retardant, there is stronger flame retardant property, and
Its bromine content is high, and thermal stability is good, exudative low compared with other bromide fire retardants, when decabromodiphenylethane thermal cracking or burning not
Generate toxic more bromo dibenzo dioxanes and polybrominated dibenzofurans, with its fire-retardant material comply fully with Europe about
The requirement of dioxin regulations does not cause damages to environment, and decabromodiphenylethane is without any toxicity, it is possible to reduce to personnel when burning
Injury, the molybdenum trioxide of addition is smoke suppressant molybdenum salt, bromine diphenylethane can not only be assisted to improve the resistance of cabinet as fire retardant
Performance is fired, and cabinet smoke amount in burning can be prevented, and do not generate droppings, generate toxic gas with raw smoke
30~80% are reduced, oxygen index (OI) improves 10~20%, can give personnel's breathing space, the graphene oxide of addition is being assisted
While bromine diphenylethane improves cabinet flame retardant property, the heat resistance of cabinet can be improved, cabinet is allow to bear higher temperature
Degree prevents a large amount of smog in addition it can assist molybdenum trioxide to improve smoke suppressing effect, in addition, the organosilicon one of addition
Poly- phthalimide copolymer not only has special physical mechanical property, improves the intensity of cabinet, and it is at high temperature, can generate glutinous
Property liquid, to make that each chemical constituent of cabinet is stable to stick together so that cabinet has certain thermal stability, because
This, while cabinet of the invention has stronger flame retardant property, intensity is higher, thermal stability is good and has smoke suppressing effect.
The technical solution that the present invention further limits is: the chemical content and parts by weight of cabinet are as follows: polyvinyl chloride resin: 10
