Abstract
The invention is suitable for the field of articles for daily use, and provides a preparation method of a glasses accessory made from polyetherimide. The preparation method comprises the following steps of: preparation of a glasses accessory precursor, annealing, surface grinding, vacuum electroplating, painting and baking. According to the preparation method of the glasses accessory, drying, annealing and electroplating under specified condition are carried out, the adhesive force of a metal film layer on the glasses accessory to the polyetherimide is greatly increased, so that phenomena of peeling, fracturing and the like of the metal film layer during bending are effectively prevented; and through coating specified paint on the metal film and then baking, the appearance of the glasses accessory is remarkably improved.
Description
Technical field
The invention belongs to daily necessities field, relate in particular to a kind of glasses accessory preparation method.
Background technology
In current ophthalmic articles, use the be in the great majority part of plastics as frame.Effect on plastic material after direct japanning can only be translucent bright cloudy colour or opaque real look, although real look also comprises light tone and cloudy colour, whole structure is still plastics appearance.Cause thus eyewear products outward appearance poor, and easily fade, the problem such as peeling.
Summary of the invention
In view of this, the invention provides a kind of PEI glasses accessory preparation method, solve PEI glasses accessory appearance poor in prior art, easily fade, the problem of peeling.
The present invention is achieved in that
A kind of glasses accessory preparation method, comprises the steps:
By dry polyetherimide processing, injection moulding, obtain glasses accessory precursor;
Be the 2-3 hour that anneals under 200 ~ 204 degree conditions by described glasses accessory precursor in temperature;
Glasses accessory precursor after described annealing in process is carried out to surface grinding processing;
Be 180～210 degree condition vacuum platings by glasses accessory precursor after treatment described surface grinding in temperature, on described glasses accessory precursor, form a metallic diaphragm;
By the glasses accessory precursor coating paint after described electroplating processes, the composition of described paint is: the epoxy diluting solvent of 50 parts of varnish pairings, the epoxy resin varnish sclerosis of 1.5 parts for the epoxy resin glasses of 100 parts;
Be to toast under 160～175 degree conditions the glasses accessory precursor after described coating paint in temperature, obtain glasses accessory.
Glasses accessory preparation method of the present invention, by dry, annealing in process, coordinate again electroplating processes under specified conditions, the metallic diaphragm on glasses accessory is increased greatly at the adhesion of polyetherimide, effectively prevent that metallic diaphragm from occurring in phenomenons such as when bending peeling, be full of cracks.
By be coated with specific paint baking on metallic diaphragm, the outward appearance of glasses accessory is significantly promoted.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention glasses accessory preparation method process flow diagram.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 shows embodiment of the present invention glasses accessory preparation method's process flow diagram, comprises the steps:
Step S01, prepares glasses accessory precursor:
By dry polyetherimide processing, injection moulding, obtain glasses accessory precursor;
Step S02, annealing in process:
Be the 2-3 hour that anneals under 200-204 condition by described glasses accessory precursor in temperature;
Step S03, surface grinding:
Glasses accessory precursor after described annealing in process is carried out to surface grinding processing;
Step S04, vacuum plating:
Be 180-210 degree condition vacuum plating by glasses accessory precursor after treatment described surface grinding in temperature, on described glasses accessory precursor, form a metallic diaphragm;
Step S05, coating paint:
By the glasses accessory precursor coating paint after described electroplating processes, the composition of described paint is: the epoxy resin of 100 parts varnish for glasses, the epoxy diluting solvent of 50 parts can, by hundred lattice and standard synthetic perspiration's test in 24 hours, also can separately add the epoxy resin glasses varnish rigidizer of 1.5 parts to extend persistence; Color can be with toner pigment distributed in demand voluntarily.
Step S06, baking:
Be to toast under 160-175 degree condition the glasses accessory precursor after described coating paint in temperature, obtain glasses accessory.
Particularly, in step S01, be dry 4-6 hour under 150 degree conditions by pure polyetherimide raw material in temperature, the moisture in polyetherimide is evaporated in a large number, be equipped with dehumidifying heat pump control moisture below 0.2%;
Use predetermined mould, for example picture frame mould, carries out injection moulding take dried polyetherimide as raw material, obtain glasses accessory precursor.Process by dry, the water cut in polyetherimide reduces greatly, realizes corresponding the reducing of inherent strain in its later stage, can effectively prevent fracture.
In step S02, the glasses accessory precursor that step S01 is obtained is 200～204 degree annealing in process in temperature, and annealing time is 2-3 hour.After annealing in process, the internal stress of this glasses accessory precursor further reduces, and can either effectively prevent fracture.
In step S03, glasses accessory precursor after step S02 annealing in process is carried out to surface grinding processing, after grinding, this glasses accessory precursor Smooth, stingless, seamless, nothing seal wound, can realize the metallic diaphragm in later stage and the increase greatly of glasses accessory precursor adhesion.
In step S04, the glasses accessory precursor that step S03 is obtained, as in vacuum environment, take tin, nickel, chromium or titanium etc. as material, forms layer of metal rete by electroplating on glasses accessory precursor.Electroplating time is 0.5-2 hour, and the even thickness of metallic diaphragm is 5-20 micron.
In step S05, to even coating paint on the glasses accessory precursor obtaining in step S04, this paint comprises the epoxy resin of 100 parts varnish for glasses, the epoxy diluting solvent of 50 parts, can, by synthetic perspiration's tests in 24 hours of hundred lattice and standard, also can separately add the epoxy resin glasses varnish rigidizer of 1.5 parts to extend persistence; Certainly color can be with toner pigment distributed in demand voluntarily.This paint sprays at twice, first sprays total amount 1/3-1/2, naturally dries to after half-dried, then sprays remaining paint, so can effectively prevent that solvent from infiltrating resin material and causing stress cracking.
In step S06, be to toast 10-45 minute under 160-175 degree condition by the glasses accessory precursor of coated paint in temperature, by baking, the adhesion of this skin of paint and metallic diaphragm increases greatly, in bake process, when baking, use the fixing glasses of specific fixture or accessory to make it the shape that holds its shape in the time of baking.
Glasses accessory preparation method of the present invention, by dry, annealing in process, coordinate again electroplating processes under specified conditions, the metallic diaphragm on glasses accessory is increased greatly at the adhesion of polyetherimide, effectively prevent that metallic diaphragm from occurring in phenomenons such as when bending peeling, be full of cracks; By be coated with specific paint baking on metallic diaphragm, the outward appearance of glasses accessory is significantly promoted.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
