Description
Technical field
The present invention relates to thermal transfer technology field in film, heat transfer film and its production in espespecially a kind of mould of elastic toy ball
Method.
Background technique
Thermal transfer is a kind of technique for forming progress synchronous with decorating printing in mould.By in forming process to plastic part
Part is decorated, and the operating procedures such as tradition decoration after molding, online production stock is reduced, to reduce production cost.At this
In technique, heat transfer film is imported in mold by transmission unit, and after die closing, the mold filling material that heat transfer film is injected is pressed into die cavity
In, decorative layer is removed from heat transfer film carrier and makes it in conjunction with plastic part by temperature and moulding pressure in die cavity, to
Mold is cooling, so that it may product is removed from carrier.
The raw material of elastic toy ball usually select foaming EVA, PU, rubber etc., while injection molding, complete in mould
Thermal transfer printing is a kind of ball novel surface trailing of toy of rising in recent years.The in-mold transfer printing of spherical surface, it is desirable that heat
Transfer film must have good strength and excellent retractility.Common heat transfer film substrate PET film, since retractility is poor,
It is difficult to meet this requirement, the PVC film for generalling use certain thickness (50~100 microns) is solved as the substrate of heat transfer film
This problem.Since transfer inks most of in PVC film do not allow easily peelable, decorative printed layer during in-mold transfer printing very much
How to be removed from PVC film carrier, just becomes a problem.The in-mold transfer printing film production method of elastic ball in production practices is led to
Often first compound a thin layer of PE film (10~20 microns of thickness) preparatory in PVC film, is then coated with one layer of fiber on PE film
Plain esters resin layer is as release layer, and then the printed patterns on release layer, selection are good viscous with having with elastic material again
The ink vehicle resin of relay, to realize thermal transfer in mould, this method solves difficult release by compound PE film
The problem of.But this method also has as a drawback that, due to needing prior compound PE film in PVC film, greatly improves heat and turns
Die cost of manufacture, in addition, causing the film waste after transferring after PVC film and PE film are compound, it is difficult to recycling benefit
With a large amount of plastic garbages difficult to deal with of generation.
Summary of the invention
For the above the deficiencies in the prior art, the present invention provides one kind without the compound PE film in PVC film, makes to transfer
