Abstract
The invention discloses a kind of polyurethane product process of surface treatment, which is characterized in that it is handled urethane solid product surface using radiation mode.Present invention process is simple, quick, applied widely, product surface performance improvement is obvious.
Description
Technical field
The invention belongs to polyurethanes technology fields, and in particular to a kind of processing side of radiotechnology to polyurethane product surface
Method.
Background technique
Radiation treatment technology has been used for the modification of the high molecular materials such as plastics at present, the application limitation in polyurethane
In the curing technology as a kind of polyurethane resin and the application in radiation hardness field.Radiation can be used as a kind of solidification means
Solidification for polyurethane resin.Chinese patent CN2017114831417.8, CN201711211846.X,
CN201710781405.7 etc. has corresponding technical application example.Polyurethane is due to the feature in its structure, radiation hardness ability
It is relatively good.Chinese patent CN201711378469.9, CN201711232234.9, CN20171066228.0,
CN201710625902.8 etc. has respective application example.But in currently available technology, radiation treatment technology is only used for gathering
In terms of urethane liquid curing, other aspects without reference to.
Summary of the invention
The purpose of the present invention is to provide one kind it is simple to operate, and the surface property of polyurethane product can be improved
Polyurethane product surface treatment method.
The present invention is that a kind of polyurethane product surface treatment work is attained in that using following technical solution
Skill, which is characterized in that it is handled urethane solid product surface using radiation mode.
As a further illustration of the above scheme, the radiation treatment is directly to expose the polyurethane product of forming
Radiation treatment is carried out under high-energy ray, can be used immediately after being disposed.
Further, polyurethane product surface treatment process is that dust, the emulsion on first removing polyurethane product surface are miscellaneous
Then matter places it in the surface treatment for receiving 50-100kGy dose of radiation under high-energy ray.
The molding mode and material of the polyurethane product are unrestricted.
The present invention is using the above-mentioned attainable beneficial effect of technical solution:
1, the present invention is handled urethane solid product surface using radiation treatment mode, with simple process, fastly
Speed, can continuous productive process the characteristics of.
2, after the present invention is handled product surface using radiotechnology, its surface property can be improved, to polyurethane system
The performance of product is advantageous, and is especially very favorable to the service life for improving Polyurethane seals.
3, the polyurethane product molding mode in the present invention and material are unrestricted, unrestricted to the shape of product.
Specific embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
The HMP cylinder material of Guangdong member star industry new material Co., Ltd production is processed into sealing element by drawing, is removed
The impurity such as dust, the emulsion on surface are placed under high-energy ray and receive the surface treatment of 50-100kGy dose of radiation, before processing
Performance afterwards is as shown in table 1.
Influence of 1 radiation treatment of table to polyurethane product performance
It can be seen from 1 test data of table after radiation treatment, the hardness and tensile strength of polyurethane product are not sent out
Changing, buckling reduces, compresses cold-resistant coefficient increase, DIN abrasion reduce, coefficient of friction reduces, and directly results in polyurethane seal
Part high and low temperature resistance and wear-resisting property get a promotion, to enhance using effect, extend service life.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection scope.
