Description
Technical field
The present invention relates to the plastics of electronics field, particularly a kind of earphone memory profile and wire plastics and preparation side
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 memory profile and wire plastics and preparation methods.The present invention has fragrance
Taste, good toughness and it is durable the characteristics of.
In order to solve the above technical problems, the present invention is realized using following technical scheme：
A kind of earphone remembers profile and wire plastics, and based on heavy constituent, it is made of with the raw material of following weight proportions：
40-50 parts of polyethylene from high pressure process, 1-4 parts of silicone,
25-35 parts of caprolactam, 5-10 parts of silica
6-10 parts of end-vinyl benzene silicone oil, 15-25 parts of polyethers,
18-25 parts of PC, 1-8 parts of white oil,
2-5 parts of porous ceramic film material, 1-3 parts of benzyl alcohol ester.
More preferably, foregoing earphone memory profile and wire plastics, based on heavy constituent, it is with the raw material system of following weight proportions
Into：
42-48 parts of polyethylene from high pressure process, 1.5-3.5 parts of silicone,
28-32 parts of caprolactam, 6-9 parts of silica,
7-9 parts of end-vinyl benzene silicone oil, 18-22 parts of polyethers,
20-24 parts of PC, 2-6 parts of white oil,
2.5-4 parts of porous ceramic film material, 1.5-2.5 parts of benzyl alcohol ester.
More preferably, foregoing earphone memory profile and wire plastics, based on heavy constituent, it is with the raw material system of following weight proportions
Into：
45 parts of polyethylene from high pressure process, 3 parts of silicone,
30 parts of caprolactam, 8 parts of silica,
8 parts of end-vinyl benzene silicone oil, 20 parts of polyethers,
22 parts of PC, 4 parts of white oil,
3 parts of porous ceramic film material, 2 parts of benzyl alcohol ester.
The preparation method of foregoing earphone memory profile and 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, by modification of nylon, polyethylene from high pressure process, PC, silicone, white oil, porous ceramic film material, benzyl alcohol ester and silica 800~
1200r/min, 30~35min is mixed at 60 DEG C -70 DEG C, pours the mixture into twin-screw granulator squeeze out afterwards, Zhi Houfeng
Dry pelletizing to obtain the final product.
Advantageous effect
Compared with prior art, aromatic odor can be distributed, makes wire rod using benzyl alcohol ester armaticity material in raw material of the invention
When in use, fragrance can be released, has effectively removed plastic cement smell and oily taste, improves the usage experience of product.Not only such as
This, the present invention is first adsorbed various fragrance, is lockked, it is made slowly to discharge, effectively enhanced fragrance using porous ceramic film material
Persistence.
Also the toughness of material is effectively increased, prevents material from becoming in use using modification of nylon in the material of the present invention
Firmly, so that earphone wire is more durable.
