Description
Technical field
The present invention relates to a kind of coating dispensing of Ge Laxin paper, belong to surface-coating technology field.
Background technology
Lattice Racine paper is extensive in industrial applications such as product packaging, labels.Lattice Racine paper have good internal intensity and thoroughly
Lightness characteristic, has the function of high temperature resistant, moisture-proof, grease proofing etc., is generally used for the product packaging of the industries such as food, medicine, at a high speed certainly
The special adhesive tape of dynamic labeling (particularly suitable high speed label stickup), two-sided tape base material trade mark, laser anti-counterfeit mark are release with other
Using etc..The general typicalness purposes of lattice Racine paper is the base stock of sticky label paper, as one of label substrate, intermediate demand
Processed by multiple tracks, be finally processed into label paper with together with other auxiliary materials.Surface coating silicone oil is Ge Laxin Zhi Hou roads processing the
One step, the grease resistance to silicone oil of printing enterprise's plaid matching Racine paper are more demanding, it is desirable to which surface uniformly coats very thin one layer
Silicone oil, because uniformly whether coating silicone oil will influence lower road coating process and last peeling force, but it is expected not disappear at the same time again
Excessive silicone oil is consumed to reduce processing cost.With post-processing and the progress of printing technology, printing enterprise more and more preference surface
The good Ge Laxin paper of grease resistance.The method for strengthening paper oil-resistant characteristic is more, and e.g., surface imposes extraordinary sizing, surface filming
Well to reduce fiber porosity, reduce fat migration and reduce the absorption to grease.Also one kind is to use lamination method, in paper
Open surface and form closing plastic film, prevent paper from being contacted with grease, so as to reach grease proofing effect, but used difficult degradation material
Material, can cause environmental problem, not be the development trend of following greaseproof.
At present, domestic commercially available lattice Racine paper and international most advanced level are also there are gap, and have the following disadvantages：
A, silicone oil process is applied, silicone oil consumption is more, causes processing cost to remain high；
B, silicone oil coating is uneven, causes release layer to be combined with label layer uneven, causes peeling force unstable, influences certainly
Dynamic labeling speed.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and lattice draw surface oil resistant can be improved by providing one kind
Property, make to have by the Ge Laxin paper of top sizing not repelling silicone oil coating, and silicone oil coat uniform consumption it is few, without being oozed in paper
Thoroughly, there are good surface grease resistance and transparency, guarantee does not influence the processes such as follow-up gluing, stripping, and other physical indexs meet
The coating dispensing of the Ge Laxin paper of lattice Racine paper standard.
The purpose of the present invention is what is be achieved through the following technical solutions：A kind of coating dispensing of Ge Laxin paper, its feature
It is：It includes the pigment, at least one acrylic resin, at least one polyethylene of at least one or two different molecular weight
Alcohol, at least one latex, at least one functional additive and optional at least one viscosity modifier, remaining is water, wherein：
Relative to coating formulation gross weight, the pigment content is by weight between 3-5%；
Relative to coating formulation gross weight, the acrylic resin content is by weight between 1-2%；
Relative to coating formulation gross weight, the polyvinyl alcohol content is by weight between 2-4%；
Relative to coating formulation gross weight, the latex content is by weight between 1-3%；
Relative to coating formulation gross weight, the functional additive content is by weight between 0.1-0.3%；
Relative to coating formulation gross weight, the viscosity-adjusting agent agent content is by weight between 0.01-0.03%；
The viscosity of coating is controlled in 500~600mPa.S after above-mentioned viscosity modifier adds.
It is further：The pigment of at least one or two different molecular weight, wherein at least one pigment is china clay,
It can be a kind of, two kinds of the pigment composition arbitrarily matched therein；
The acrylic resin is aqua type thermosetting resin, molecular weight ＞ 10000；The latex is artificial synthesized
Latex；The functional additive has been the modified cellulose of thickening power；
Its degree of polymerization of the polyvinyl alcohol is 1000~3000, its alcoholysis degree is not less than 50%.
Moreover：The synthetic latex is one kind of styrene-acrylic latex or styrene-butadiene latex；The function addition
Agent has been the carboxymethyl cellulose of thickening power；The polyvinyl alcohol is PVA1799；The viscosity modifier is 5% dense
The sodium hydrate aqueous solution of degree.
The purpose of present invention addition pigment is increase coating layer thickness, and be formulated has certain adhesion to silicone oil, will not be complete
Repel silicone oil.Increase surface smoothness at the same time, improve glossiness.
Controlling the purpose of viscosity, sizing is uniform with ensureing being smoothed out for coating process.
The present invention addition polyvinyl alcohol purpose make formula that there is more superior water resistance and film forming, not moisture-sensitive and
Keep transparency.
The purpose of present invention addition latex is there is more excellent grease resistance with the formula that other components are formed, and avoids silicon
Oil is permeated into paper.
The beneficial effects of the invention are as follows：The Ge Laxin paper being coated with by this dispensing surface, has and does not repel silicone oil coating, together
When silicone oil coating consumption is few, coated side uniformly, without the good surface grease resistance permeated in paper.Key physical index：Oil
Cobb values≤0.15g/ ㎡, transparency >=40%.
