Description
Technical field
The present invention relates to the plastics of electronics field, particularly a kind of earphone wire plastics and preparation method.
Background technology
As people's quality of life is continuously improved, people are to earphone product no matter from appearance, tonequality, material, use quality
Everyways is waited to have a higher requirement, in earphone product, plastic material is the main material of earphone product, however, current institute
There is plastic material after product is made in overmolding, in the case where properties of product basically reach requirement, it is serious all to deposit plastic cement smell,
The problems such as oil is highly seasoned, makes staff, consumer be difficult to receive.Moreover its folding resistance, elasticity is not enough, ageing-resistant,
Long-time service can be hardened, be not easy to reply shape, product elasticity and flexibility deficiency.
The content of the invention
It is an object of the present invention to provide a kind of earphone wire plastics and preparation methods.The present invention has aroma type, toughness
The characteristics of good and durable.
In order to solve the above technical problems, the present invention is realized using following technical scheme：
A kind of earphone wire plastics, based on heavy constituent, it is made of with the raw material of following weight proportions：
30-40 parts of ethylene-butene copolymer, 35-45 parts of caprolactam,
8-12 parts of end-vinyl benzene silicone oil, 20-30 parts of polyethers,
10-20 parts of PP, 3-10 parts of white oil,
1-4 parts of porous ceramic film material, 0.5-2 parts of ethyl acetate,
3-10 parts of silica.
More preferably, foregoing earphone wire plastics, based on heavy constituent, it is made of with the raw material of following weight proportions：
32-38 parts of ethylene-butene copolymer, 36-42 parts of caprolactam,
9-11 parts of end-vinyl benzene silicone oil, 22-28 parts of polyethers,
12-16 parts of PP, 5-8 parts of white oil,
2-3.5 parts of porous ceramic film material, 0.8-1.5 parts of ethyl acetate,
4-8 parts of silica.
More preferably, foregoing earphone wire plastics, based on heavy constituent, it is made of with the raw material of following weight proportions：
35 parts of ethylene-butene copolymer, 38 parts of caprolactam,
10 parts of end-vinyl benzene silicone oil, 25 parts of polyethers,
14 parts of PP, 7 parts of white oil,
3 parts of porous ceramic film material, 1 part of ethyl acetate,
6 parts of silica.
The preparation method of foregoing earphone wire plastics, is prepared according to the following steps：
A, by caprolactam, end-vinyl benzene silicone oil, polyethers be dropped in 1500~2000r/min, mixing 15 at 50 DEG C -60 DEG C~
Modification of nylon is made in 20min；
B, modification of nylon, ethylene-butene copolymer, PP, white oil, porous ceramic film material, ethyl acetate and silica are existed
1000~1500r/min, 25~30min is mixed at 60 DEG C -70 DEG C, pours the mixture into twin-screw granulator squeeze out afterwards,
Air-dry pelletizing afterwards to obtain the final product.
Advantageous effect
Compared with prior art, aroma gases are stored, make line using ethyl acetate armaticity plastic material in raw material of the invention
Material when in use, fragrance can be released, effectively removed plastic cement smell and oily taste, improved the usage experience of product.Not only
In this way, the present invention can adsorb various fragrance, and slowly release enhances fragrance in use in advance using porous ceramic film material
Persistence.
Modification of nylon also is made using caprolactam, end-vinyl benzene silicone oil and polyethers in the material of the present invention, effectively increases
The toughness of material is added, material is prevented to be hardened in use, so that earphone wire is more durable.
