Description
Technical field
The invention belongs to industrial products protection field, more particularly to a kind of fogless shadow Protection glue band and preparation method thereof.
Background technology
During Protection glue band is widely used in industrial processes and industrial products final protection field, for interim protection
Part or product surface, prevent cut or stain, final to be removed from surface is pasted again.This special purposes is determined
Protecting film must possess following performance：First, to needing surface to be protected to have fabulous adhesion；2nd, needing to remove
When can with minimum peeling force from by protection surface easy removal, and ensure do not leave any vestige；3rd, protected by guard period
Retaining tape will not cause because of self deterioration product surface contaminated or damage.
Protection glue band leaves " mist shadow " after removing be that Protection glue band is common in application process and very scabrous pollution
Problem, specifically refers to Protection glue band and is pasted be retained in after surface removes by the shallow mist on patch surface, but not cull.It is this
Specifically now it is that surface of plastic products in mirror face stainless steel, bright face is particularly evident, this brings greatly tired to product protection
Disturb, serious even can scrap products.It has been generally acknowledged that " mist shadow " be Protection glue with the low molecule quality material in adhesive from glue
Layer is to being caused by patch surface migration, therefore to reduce the content of low molecule quality material in adhesive be that to solve " mist shadow " most practical
Effective method.
At present, the method for comparing main flow is to prepare the protection that Protection glue band is used as bright Flour product using coextruding method, so as to
" mist shadow " problem of solution.
The content of the invention
