Abstract
The invention discloses a kind of coating of write erasing on PET film, this can be write erasing coating and use modified polyacrylic acid to be coating main body, and this modified polyacrylic acid has splendid hydrophilic so that various pens all easier can be write above, and writing is clear, it is difficult to dizzy dye；This polyacrylic resistance to water is strong simultaneously, still can keep stable through repeatedly cleaning, and persistency is strong.Using this can write erasing coating application on a pet film can be stable with processability, and what persistency was strong can writing film.
Description
Technical field
The present invention relates to paint field, particularly relate to a kind of on PET film, write-wipe coating.
Background technology
Polyester film (PET film) has physical property, chemical property and dimensional stability, the transparency of excellence and can return
The property received, therefore PET film is widely used in magnetic recording, sensitive material, electronics, electric insulation, screen protection, industrial film, bag
The fields such as dress decoration or optical grade minute surface protection.
The various performances of PET film make its be very suitable for as can writing film layer, but due to PET film smooth surface, hydrophilic
Property is poor, therefore writes in pet sheet face and acquires a certain degree of difficulty, causes writing too also due to the adhesion on PET film surface is the least in addition
Easily it is rubbed off.Further, since PET film has the problems such as case hardness is low, anti-wear performance is poor so that PET film is at writing process
In easily by swiping, polishing scratch is occurred so that the service life of writing film is the shortest, limit PET film range.At PET film
Surface-coated one layer can write-wipe coating, changes the inherent characteristics of PET film, increases the anti-wear performance of PET film, is so that PET
Film surface is prone to write, be prone to the effective and easy mode of erasing.
Chinese patent CN201510976149.8 discloses and a kind of repeatable writes coating, object and preparation method thereof, its
Comprising photochromic material and/or changing color resulting from acid material, described coating presents metachromatism and can in predetermined wavelength range
Do not present metachromatism in seeing optical range, and/or described coating does not present metachromatism in acid pH range.This repeatable number
Aobvious coating has that preparation technology is simple, low cost, printing precision high and the advantage of writing persistent period length.
Summary of the invention
It is an object of the invention to provide and a kind of write-wipe coating on PET film, this coating can make PET film
It is prone to write, wipe, time Palingraphia can be gone up and use.This Paint Adhesion is high simultaneously, has stronger wear-resisting, Marresistance
Can, preparation method is simple, has good prospects for commercial application.
For achieving the above object, the present invention is by the following technical solutions:
A kind of on PET film, write-wipe coating, it is characterised in that in parts by weight, including following components:
Modified polyacrylic acid 100 parts, polyvinyl alcohol 30-40 part, calcium iso-octoate-4%4-5 part, surfactant 3-7 part,
Firming agent 12-24 part, delustering agent 2-7 part, levelling agent 6-13 part, water 30-50 part.
Preferably, described modified polyacrylic acid is by acrylic acid, N hydroxymethyl acrylamide, dimethylaminoethyl acrylate methyl ammonia second
Ester, methacrylic acid glycidyl methacrylate is polymerization monomer, and with potassium peroxydisulfate as initiator, polymerization is prepared from.
Preferably, described surfactant is dodecylbenzene sodium sulfonate, cocamido propyl betaine or butane group phenol
One or more in polyoxyethylene ether.
Preferably, described firming agent is hexamethylene diisocyanate, the one in isocyanates urea ester or toluene di-isocyanate(TDI)
Or multiple mixture.
Preferably, described delustering agent is poly-MU resin and the mixture of silicon dioxide, the most poly-MU resin with
The mass ratio of silicon dioxide is 5:2.
Preferably, described levelling agent is that one or more in hydroxymethyl cellulose, polyoxyethylene ester or sodium laurate are mixed
Compound.
Preferably, described coating is UV curing type.
The invention have the advantages that, using modified polyacrylic acid is coating main body, and this modified polyacrylic acid has
Splendid hydrophilic so that various pens all easier can be write above, and writing is clear, is difficult to dizzy dye；Should simultaneously
Polyacrylic resistance to water is strong, still can keep stable through repeatedly cleaning, and persistency is strong.Use this can write-wipe coating
Brushing on a pet film can be stable with processability, and what persistency was strong can writing film.
