Description
Technical field
The present invention relates to cold lamination film field, more particularly to a kind of preparation method of fire-retardant cold lamination film.
Background technology
In order to make the outdoor advertising life-span longer, photograph can have height anti-corrosive properties and anti-ultraviolet erosion, for a long time
Chang Xin, it is colour-fast, do not turn yellow, people start with transparent protective film and are covered on picture.The air brushing of air brushing membrane material makes
Afterwards because ink is in the surface of film, easily moist by moisture content in air, the natural cause influence such as sunlight, the easy oxygen of ink
Change or change colour, then, printing film surface needs PVC cold lamination films to be protected to arise at the historic moment, and solves printing ink oxidization image fault
Puzzlement.
It is although big there is can also be produced the defects of easy burning, and in burning but PVC material does not produce naked light
The toxic smoke of amount, outdoor advertising currently on the market often uses with outdoor lamp house collocation, therefore has been easier flammability issues, therefore opens
It is an important directions for developing new product to send out flame retardant type cold lamination film a kind of.But asked now below PVC cold lamination film generally existings
Topic：(1) glue is generally combustible material so that PVC cold lamination film fire resistances are not up to standard；(2) but if the inorganic resistance of glue
Combustion powder addition it is excessive not only caused by with PVC cold lamination films the problem of compatibility be present, can also influence the transparency of cold lamination film.
The content of the invention
In order to overcome existing technical deficiency, the invention provides a kind of preparation method of fire-retardant cold lamination film.
To achieve these goals, the technical scheme taken of the present invention is：
A kind of preparation method of fire-retardant cold lamination film, comprises the following steps：
(1) flame retardant type transparent adhesive tape water layer is weighed into component by following weight white powder ratio：
The phosphorous acrylic monomers is 2- ethyls (methacrylic acid acyloxymethyl) phosphonate ester, 2- ethyl (acryloyl-oxies
Methyl) one or more in phosphonate ester and 2- ethyls (methacrylic acid acyloxymethyl) phosphate；
(2) flame retardant type transparent adhesive tape water layer is prepared：All components in addition to initiator and curing agent are well mixed, Ran Houjia
Enter initiator, 70-90 DEG C of reaction 7-9h, then add curing agent and stir；
(3) flame retardant type transparent adhesive tape water layer 15-30g/m is coated with flame retardant type transparent PVC film body layer2, coating speed is
20-40m/min, after drying, and after white silicon paper layer is bonded, winding.
Butyl acrylate, methyl methacrylate, acrylic acid, propenyl and phosphorous acrylic monomers are triggered through initiator
Copolymerization, a kind of new flame-retardant polymer is made.It can pass through carboxyl and carboxyl, carboxyl and hydroxyl inside manufactured flame-retardant polymer
The hydrogen bond of base, carboxyl and amide groups, hydroxyl and amide groups, hydroxyl and hydroxyl, acid amides and acid amides forms meshed super molecular structure, makes
Polymeric inner forms network structure, and and melamine, form P-C-N Intumescent Retardant System.It is so viscous in increase
While spending, good flame retardant effect is reached.But melamine and the compatibility of this system are not so good, add a small amount of
Nitric acid adjusts pH value, can increase N content, increases anti-flammability, and can adjusts the compatibility of whole system, and increase significantly is transparent
The light transmittance of glue layer.But the amount of nitric acid crosses conference and causes the unstable of its internal network structure so that viscosity is greatly reduced,
Effect is not reached.
Preferably, phosphorous acrylic monomers, melamine and nitric acid form flame-retardant system in the step (1), when it
Weight ratio is 2-2.5：1：0.03-0.05, the P-C-N flame-retardant systems of formation, in the case where fire retardant addition is seldom, also can
Reach good flame retardant effect.
Preferably, the weight of melamine and nitric acid ratio is 1 in the step (1)：0.04, under this system, nitric acid
Addition it is excessive, whole glue system can be influenceed, easily cause it is sticky not enough.But addition is too small, make melamine with
The compatibility of whole system is bad, influences transparency.
Preferably, phosphorous acrylic monomers is 2- ethyls (methacrylic acid acyloxymethyl) phosphate in the step (1).
Phosphate can be decomposed to form orthophosphoric acid, and it is good to be catalyzed into carbon effect, therefore 2- ethyls (methacrylic acid acyloxymethyl) phosphate
Addition it is less in the case of, same flame retardant effect can be reached.
Preferably, curing agent is the curing agent containing NCO group in the step (1).Such as can be toluene diisocynate
Ester (TDI)；Methyl diphenylene diisocyanate (MDI).Hydroxyl (- OH) in propenyl after NCO group reaction with that can form friendship
Join network structure.So that P is distributed more evenly across inside flame retardant type transparent glue, therefore in the case where P content is less, also can
There is good flame retardant effect.
Preferably, step (1) initiator is ammonium persulfate.
Preferably, in the step (3), the drying course is, is 55 by the temperature gradient distribution of removable pressure sensitive adhesive
℃-60℃-65℃-70℃-65℃-60℃-55℃。
The present invention is advantageous in that：
1. fire-retardant cold lamination film fire resistance provided by the invention can reach VTM-2 fire-protection rating；
2. fire-retardant cold lamination film transparency provided by the invention is high.
