Description
Technical field
The present invention relates to a kind of coating dispensing of Ge Laxin paper, belongs to surface-coating technology field.
Background technology
Lattice Racine paper is extensive in industrial applications such as product packaging, labels.Lattice Racine paper has good internal intensity and thoroughly
Lightness characteristic, with the function such as high temperature resistant, protection against the tide, grease proofing, 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 is release with other
Using etc..The general typicalness purposes of lattice Racine paper is the base stock of sticky label paper, used as one of label substrate, intermediate demand
Through multiple tracks processing, finally label paper is processed into together with other auxiliary materials.Surface coating silicone oil is Ge Laxin Zhi Hou roads processing the
One step, the grease resistance requirement to silicone oil of printing enterprise's plaid matching Racine paper is higher, it is desirable to which surface uniformly coats very thin one layer
Silicone oil, because whether uniformly coating silicone oil will have influence on lower road coating process and last peeling force, but while and expects not disappear
Consume excessive silicone oil to reduce processing cost.With rear 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 applying glue, surface filming
Well to reduce fiber porosity, reduce fat migration and reduce the absorption to grease.An also class is to use film method, in paper
Open surface and form closing plastic sheeting, prevent paper from contacting with grease, so as to reach grease proofing effect, but be the use of difficult degradation material
Material, can cause environmental problem, not be the development trend of following greaseproof.
At present, with international most advanced level also there is gap in domestic commercially available Ge Laxin paper, and suffer from the drawback that：
A, painting silicone oil operation, silicone oil consumption is more, causes processing cost to remain high；
B, silicone oil coating are uneven, cause release layer to be combined with label layer uneven, cause peeling force unstable, affect certainly
Dynamic labeling speed.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and providing one kind can improve lattice draw surface oil resistant
Property, there is the Ge Laxin paper through top sizing and do not repel silicone oil coating, and silicone oil coat uniform consumption it is few, without oozing in paper
Thoroughly, there are good surface grease resistance and transparency, it is ensured that do not affect the operations such as follow-up gluing, stripping, and other physical indexs to meet
The coating dispensing of the Ge Laxin paper of lattice Racine paper standard.
The purpose of the present invention is achieved through the following technical solutions：A kind of coating dispensing of Ge Laxin paper, its feature
It is：It includes 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 viscosity modifier content is by weight between 0.01-0.03%；
The viscosity of coating is controlled in 500～600mPa.S after above-mentioned viscosity modifier addition.
It is further：The pigment of at least one or two different molecular weight, wherein at least one pigment is china clay,
Can be a kind of, pigment composition of two kinds of any proportioning therein；
Described acrylic resin be aqua type thermosetting resin, molecular weight ＞ 10000；Described latex is artificial synthesized
Latex；Described functional additive has been the modified cellulose of thickening power；
Its degree of polymerization of described polyvinyl alcohol is 1000～3000, and its alcoholysis degree is not less than 50%.
Moreover：Described synthetic latex is one kind of styrene-acrylic latex or styrene-butadiene latex；Described function addition
Agent has been the carboxymethylcellulose calcium of thickening power；Described polyvinyl alcohol is PVA1799；Described viscosity modifier is 5% dense
The sodium hydrate aqueous solution of degree.
The purpose of present invention addition pigment is to increase coating layer thickness, and formula has certain tack to silicone oil, will not be complete
Repel silicone oil.Increase surface smoothness simultaneously, improve glossiness.
The purpose of control viscosity is being smoothed out with coating process is ensured, applying glue is uniform.
The present invention addition polyvinyl alcohol purpose make formula have more superior resistance to water and film forming, not moisture-sensitive and
Keep transparency.
The purpose of present invention addition latex is that the formula formed with other components has more excellent grease resistance, it is to avoid silicon
Oil permeates into paper.
The invention has the beneficial effects as follows：Through the Ge Laxin paper of this dispensing surface coating, coat with silicone oil is not repelled, together
When silicone oil coating consumption is few, coated side uniform, without the good surface grease resistance permeated in paper.Key physical index：Oil
Cobb values≤0.15g/ ㎡, transparency >=40%.
