Description
Technical field
The present invention relates to technique for treating plastic surface fields, in particular to a kind of plastics gold disk and preparation method thereof.
Background technology
As plastic processing and modification technology are continuously improved, application field extends rapidly.Different application field is to plastic table
The performance requirements such as face decoration, material protection, improvement bonding are increasing, but various plastic material structures are different from component, accordingly
Surface property also have notable difference.The various process for treating surface for adapting to different application come into being with product.Adapt to plastics
The different of surface treatment need, and developed there are many treatment technology.Common technology has：Solvent cleans (degreasing), corona
Processing, short wave ultraviolet light radiation treatment, sand paper processing, sandblast, plasma etching, chemical etching, heat treatment etc..For
Different materials, it is often necessary to select different processing methods.
Since the surface energy of most of plastics is low, many processing methods, such as decoration, printing, spraying all cannot directly fit
With, and need to be surface-treated first.The cementability of plastics and various different materials is that surface treatment needs one solved
Critical issue.In general, plastic bonding performance is related with material structure and component.
The polyolefine materials such as PP and PE, surface energy is very low, usually only 30-34 dynes.Realize good bonding, one
As require surface energy be not less than 40 dynes.Adhesive test shows that PE adhesive strengths after plasma treatment can be improved 10 times；By
After chromic acid processing, adhesive property about can be improved 5 times.By equally handling, PP adhesive strength appointments after ionization processing improve
200 times, and can then improve 600 times after chromic acid processing.
Why chromic acid is so significant to the treatment effect of PP, and quite different to PEThis is because each carbon on PP segments
All there are one methyl (- CH3) for atom.Methyl by oxygen ionized or chromic acid after handling easily by carboxylic-oxidized.Moreover, i.e.
Only seldom methyl is set to be aoxidized, the adhesive property of PP is with polarity as the presence of carboxyl and significant improvement.And PE is then
Without this group.As can be seen that the chemical constitution of polymer is the key factor that must take into consideration when being surface-treated.
The method for making plastics gold disk at present generally includes following steps：
(1) injection molding ground is subjected to pickling, carries out pre-treatment later, for example use cloth by the surface of the ground after pickling
Wiped clean；
(2) in the surface spraying foliation adhesive of ground, the forms such as the method for gluing may be selected spray, brush, smear, before gluing
Glue need to be filtered with filter cloth, glue-line will equably scumbling, touched with finger, feel toughness, but finger is pollution-free to paste
Foil；
(3) required foil paper (such as goldleaf or silver foil) is sticked；Foliation place needs ventilation, drying, and foliation work need to be worn soft
Mitten forbids the surface for directly touching foil with hand, after completing foliation process, need to use between soft cloth or cotton balls compacting, pressing foil face
Gap；
(4) foil is swept；After the completely densified of foil paper face, start to sweep foil, sweep the hairbrush of foil softness, gently by foliation direction
Lap is swept off, foil face is made to keep flat smooth, cleaning；
(5) after the completion of sweeping foil, then its surface spraying is transparent or protective paint with background color；Such as clinquant (copper foil),
Imitative silver foil (aluminium foil), true silver foil are more oxidizable products, 3~5 hours generally after having pasted foil, last layer neutrality protective agent,
It,, can types such as upper 1~2 strata ester again if you need to improve foil surface hardness to prevent foil face from changing colour or scratch such as 5# metal foil Protection glues
Clear varnish；
(6) after the completion of sweeping foil, surface can further be polished smooth, sprays transparent or colored face again later
Paint；
(7) it is packed after surface and the back side are completely dried.
But the above method has the following disadvantages：
1. carry out pre-treatment to the injection molding ground after pickling, the residual of the pickling on surface can not be wiped with common calico
Liquid medicine, or even can leave more soft flocks and dust, causes product not wipe clean really, seriously affects product quality and (for example goes out
Point of now painting and other flaws)；
2. being mostly manual brush coating at present, goldleaf or silver foil have many brush coating lines, and product disunity after sticking
It is very high to brush coating worker requirement, if glue is blocked up, the reasons such as goldleaf discoloration are will produce, if brushing is uneven to cause depainting
And other various problems；
3. most of product by 9 goldleaf by hand patch at, had the gap between every goldleaf, influence product beauty, and by
Too thin in foil paper, each product has many manual flaws, and (goldleaf cracks, goldleaf oxidation, goldleaf color disunity etc. many
Problem)；
4. it is that the goldleaf lap that will be sticked is swept with mosquito netting to sweep foil, a large amount of foil can be caused when sweeping foil
Ash has harmful effect to the health of worker；A large amount of foil ash also seriously affects product quality and (causes particle) simultaneously, in addition
The goldleaf that sweeping can not sweep after foil in every foil paper gap can form serious product surface not after spraying first of finishing coat
It is flat, scrape hand；
5. being mostly artificial spray painting, uniformity assurance is bad, causes product colour disunity, the uneven depth of surface color
Differ；
6. polishing：There are a large amount of dust, worker's body is damaged, polishes as manual grinding, be unable to reach each production
Product are all unified, and polishing degree is deep mixed, has a large amount of dust on the product after polishing, it is difficult to wiped clean.
In view of this, special propose the present invention.
