Description
Technical field
The present invention relates to capacitor technology field, more particularly to a kind of capacitor modified plastics shell.
Background technology
Capacitor is one of electronic component largely used in the electronic device, be widely used in blocking, coupling, bypass,
Filtering, resonant tank, energy conversion, control circuit etc..But existing plastic capacitor shell material, to light and heat
Stability is poor, by the influence of long-term electromagnetic radiation, physical mechanical property can be caused also to decline rapidly, and brittleness is larger and anti-impact
Degradation is hit, can not meet the needs of many occasions.
The content of the invention
The object of the present invention is to provide a kind of capacitor modified plastics shells.
The invention is realized by the following technical scheme：
A kind of capacitor modified plastics shell, is made by weight of following component：Polybutylene terephthalate (PBT)
70-90, ABS plastic 35-45, filler 8-12, color masterbatch 1-3, Dimethyl Trimethylsilylmethylphosphonate 4-7, Corvic
12-15, lubricant 3-6, modifying agent 0.5-0.8；The modifying agent is made by weight of following component：Carboxycellulose 3-
5th, sorbitol olein 2-6, rosin 8-10, calgon 1-3, alkali lignin 2-4, acrylamide 2-4, diatomite 1-4, three
Polyphosphate sodium 1-3, gaultherolin 1-4, tea-seed oil 4-6, peppermint oil 0.1-0.3.
Further, the weight ratio of the polybutylene terephthalate (PBT) and ABS plastic is 2:1.
Further, the lubricant is odium stearate, olein presses 2.5:1 mass ratio mixes.
Further, the filler is any one of glass fibre, glass microballoon, mica or multiple combinations.
Further, the preparation method of the modifying agent is as follows：
A mixes carboxycellulose, diatomite, peppermint oil, is ground 40min, is then mixed with tea-seed oil；
B mixes sorbitol olein, rosin, adds in calgon, is heated to 60-65 DEG C, keeps the temperature 10min, so
Alkali lignin, acrylamide are added afterwards, and 25min is kept the temperature under the conditions of 82-87 DEG C；
C mixes step a products with step b products, adds in remaining residual components, small with the speed stirring 4 of 2500r/min
When to obtain the final product.
The invention has the advantages that compared with prior art：
Plastic capacitor shell prepared by the present invention, good mechanical property, processing performance is good, cost and melt viscosity are low, resists
Impact strength is good with heat aging property, has excellent thermal stability.The modifying agent that the present invention prepares, it is only necessary to seldom use
Amount just can substantially play increasing action；The machine of plastic capacitor shell can not only be enhanced after the modifying agent that the addition present invention prepares
Tool intensity also improves the heat distortion temperature, mechanics temperature and electrical insulation capability of plastic capacitor shell to a certain extent；Respectively
Ingredient is preferably obtained by lot of experiments so that the same polybutylene terephthalate (PBT) of modifying agent, the ABS that the present invention prepares
The compatibility of plastics is good, improves mixed system institutional framework composition, is mixed more uniformly between each ingredient, institutional framework is more
Securely, in processing and forming engineering, do not decompose, also do not react with other materials, good weatherability after shaping, stability
Height, service life are greatly extended.
Specific embodiment
Embodiment 1

Calgon 1, alkali lignin 2, acrylamide 2, diatomite 1, sodium tripolyphosphate 1, gaultherolin 1, tea-seed oil 4, peppermint oil
0.1。
Embodiment 2
A kind of capacitor modified plastics shell, is made by weight of following component：Polybutylene terephthalate (PBT)
90th, ABS plastic 45, filler 12, color masterbatch 3, Dimethyl Trimethylsilylmethylphosphonate 7, Corvic 15, lubricant 6, change
Property agent 0.8；The modifying agent is made by weight of following component：Carboxycellulose 5, sorbitol olein 6, rosin
10th, calgon 3, alkali lignin 4, acrylamide 4, diatomite 4, sodium tripolyphosphate 3, gaultherolin 4, tea-seed oil 6, peppermint
Oil 0.3.
Embodiment 3
A kind of capacitor modified plastics shell, is made by weight of following component：Polybutylene terephthalate (PBT)
80th, ABS plastic 40, filler 9, color masterbatch 2, Dimethyl Trimethylsilylmethylphosphonate 6, Corvic 14, lubricant 5, change
Property agent 0.7；The modifying agent is made by weight of following component：Carboxycellulose 4, sorbitol olein 3, rosin 9,
