Description
Technical field
Receive material the present invention relates to digitized video, more particularly to a kind of waterborne flame retardant bright gum PVC in vain preparation method.
Background technology
In recent years, green product enjoyed people to pay close attention to, and government also advocates environmental protection cause energetically.Market today 80% with
On gum PVC products be all to use oiliness glue, contain the carcinogenic chemical such as benzene composition or release VOC gas hostile environment.
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, flammability issues are also easier to, therefore bright gum PVC is develop new product one to a kind of waterborne flame retardant of exploitation in vain
Important directions.But gum PVC generally existings once problem now：(1) primer is generally combustible material so that gum PVC hinders
It is not up to standard to fire performance；(2) but if compatibility be present with gum PVC caused by the inorganic fire-retarded powder addition of primer is excessive
Problem, influence viscosity and easy cull when show and colour is removed.
The content of the invention
In order to overcome existing technical deficiency, the invention provides a kind of waterborne flame retardant bright gum PVC in vain preparation method,
The waterborne flame retardant bright gum PVC not only good flame retardation effects in vain, 100% cull can be removed, and antioxygenic property is good, is not easy old
Change, colour-fast, curved surface stickup property is good.
To achieve these goals, the technical scheme taken of the present invention is：
It is described to comprise the following steps：
(1) flame retardant coating is prepared：By weight percentage, 10-30% fire retardants and 0.1-0.5% wetting agents are dissolved in
In 69.5-89.9% poly-vinyl alcohol solutions, it is well mixed；
The fire retardant is the mixture of aluminium hydroxide, APP and melamine, and its weight ratio is 1-2：1-3：
0.3-1.5；The poly-vinyl alcohol solution is solid containing being 8-15%, and viscosity is 1000-8000cps/30 DEG C；
(2) fire retardant glue water layer is prepared：By weight percentage, by butyl acrylate 38-50%, methyl methacrylate 6-
12%th, acrylic acid 2-6%, propenyl 4-8%, phosphorous acrylic monomers 10-17%, melamine 3~8% and alkyl sulfate
0.1-0.3% is well mixed, and is then added 2-4% initiators, 70-90 DEG C of reaction 7-9h, is then added 1-5% latex powders, 2-
6% nano-attapulgite continues to react 1-3 hours；3-8% curing agent is added after being cooled to normal temperature, stirs 20-40 minutes, mistake
Filter；Preferably, alkyl sulfate ten is sodium dialkyl sulfate.
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.
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
Alkyl sulfate, S contents can be increased, increase anti-flammability, and can adjusts the compatibility of whole system.But alkyl sulfate
Measuring conference causes the foam number of system big so that polymerisation is ineffective, influences the reaction effect of whole system.
(3) flame retardant coating 15-30g/m is coated with white PVC layer2, after drying；It is coated with white PVC layer another side
Fire retardant glue water layer 15-30g/m2, coating speed 20-40m/min, after drying, and after release white silicon paper layer is bonded, receive
Volume.
Preferably, wetting agent is polyacrylic acid sodium salt in the step (1).A small amount of polyacrylic acid sodium salt can just make this
Flame retardant coating adhesive force in white PVC film is pretty good.
Preferably, aluminium hydroxide, APP and the melamine weight ratio in the step (1) are 1：1.5-2.5：
0.5.If extinguishing waterborn face apply add fire retardant amount it is excessive not only have face apply system compatibility the problem of, and
Problem also occurs with the compatibility of white PVC layer and ink, has not only influenceed colour vividness but also has influenceed the persistence of picture.Therefore
Add aluminium hydroxide, the fire retardant of melamine absorption-type and APP to be compounded, extinguishing waterborn face can be increased and applied and oil
The compatibility of ink.
Preferably, phosphorous acrylic monomers, the weight ratio of melamine are 1.5-2 in the step (2)：1.Phosphorous propylene
The P-C-N flame-retardant systems that acid monomers, melamine are formed, under the system of the present invention, when its weight ratio is 1.5-2：1, hindering
In the case that combustion agent addition is seldom, it can also reach good flame retardant effect.
Preferably, hundred parts of ratios of weight of alkyl sulfate are 0.2-0.3% in the step (2).Due to adding in body series
Melamine is entered, the compatibility of nano-attapulgite and whole system is bad, therefore to add wetting agent.But in this individual
In system, if hundred parts of ratios of the weight of alkyl sulfate, if it exceeds when being 0.3%, will also result in the problem of compatibility is bad (can
Can be due to foaming, it is difficult to carry out completely to make polymerisation).It has been surprisingly found that in this system, add 0.2-
0.3wt% alkyl sulfate removes cull with regard to the anti-flammability and 100% that can greatly improve whole system.
Preferably, in the step (2), the weight ratio of the latex powder and nano-attapulgite is 1：1-2.Further
Preferably, the latex powder and the weight of nano-attapulgite ratio are 1：1, latex powder and bumps are added in fire retardant glue water layer
After rod soil, bright gum PVC 100% can remove not cull to the waterborne flame retardant in vain, and waterborne flame retardant bright gum PVC in vain curved surface glues
Patch property is good, and bubble-free produces.
Preferably, phosphorous acrylic monomers described in the step (2) is 2- ethyls (methacrylic acid acyloxymethyl) phosphorus
Acid esters.Phosphate can be decomposed to form orthophosphoric acid, and it is good to be catalyzed into carbon effect, therefore 2- ethyls (methacrylic acid acyloxymethyl) phosphorus
In the case that the addition of acid esters is less, same flame retardant effect can be reached.
Preferably, curing agent described in the step (2) is the curing agent containing NCO group.Such as can be that toluene two is different
Cyanate (TDI)；Methyl diphenylene diisocyanate (MDI).Hydroxyl (- OH) in propenyl and energy shape after NCO group reaction
Into cross-linked 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 there can be good flame retardant effect.
Preferably, initiator is ammonium persulfate described in the step (2).
The present invention is advantageous in that：
1. bright gum PVC fire resistances can reach VTM-2 fire-protection rating to waterborne flame retardant provided by the invention in vain；
2. product coating designs, ensure exquisite fine and smooth printout picture, high color reproduction degree.
3. special glue design, while flame retardant effect is ensured, and can 100% removal cull, and inoxidizability
Can be good, non-aging, colour-fast, curved surface stickup property is good.
4. it can be useful on water-based air brushing and description printing device, such as Hp, Roland, Mutoh, Mimaki, Seiko, force
Rattan etc..
