Synthetic plastics pigment constantly is used for the coating of paper, partially or completely substitutes conventional mineral dye such as lime carbonate and kaolin.Plastic pigment is commonly used for water dispersion, that is, latex, wherein dry matter content is a 20-60% weight.Synthetic plastics pigment can have solid core or they can be hollow.Chemically, these plastic pigments are based on polyacrylic ester, polymethacrylate or polystyrene or its multipolymer, and can use other pigment based on urea-formaldehyde and melamine-formaldehyde.Plastic pigment, especially hollow particle pigment are given by its product made from opacity and brightness.But a problem that relates to the plastic pigment water dispersion is that stability in storage is limited to, and solid polymer particle often is deposited in the bottom of container in the standing storage process.In addition, plastic pigment is not cold-resistant usually to be frozen and melts, and also cohesion when freezing easily of polymer pigment.Therefore, storing temp has limited its storage.In addition, the water dispersion of plastic pigment is easy to microorganism growth.For this reason, plastic pigment becomes a kind of useless product easily.The water content of plastic pigment water dispersion is generally 40-80%, so the transportation of water has brought significant extra-expense.
The coating of paper is generally undertaken by use a kind of pigment dispersion or lotion that comprises 30-40% water usually on paper web.The drying of White Board is the process of a power consumption, because water must be removed with for example infrared dryer.This environmental pollution by water therefore must be through being discharged into it in the surface water after careful the processing.In addition, the coating line with paper machine of its lotion kitchen cabinet be the many spatial of needs than bigger device, and the coating line of paper machine is a very important investment.
Recently, developed a kind of the injection and be used for the new dry-coated method that paper is coated with, its conserve water, energy and raw material by ion.Dry-coated paper web drying-free is not therefore because of the drying consumed energy.In addition, the space that this paper machine need be more less than routine.In this new dry-coated method, use a kind of transfer of granules technology of spraying that dry colour is administered on the paper web based on ion.This method has also been utilized short grained adhesive property.By using the ion spraying technique coating material of finely divided particulate form to be transferred on the surface of paper web, these particles can be bonded on the paper fiber and directly and bond mutually, need not other binding agent.In the method, the ion that utilizes high pressure to produce sprays, and lotion is administered on the paper web and need not contact, wherein the ion that forms by corona discharge of particle and charged.Then, electric field is transferred to charged particle on the paper web.Many quality parameters of paper are also provided, because paper base material rewetting and dry more not.Above instruction hint, significant need is a kind of to be specially adapted to the synthetic plastics pigment of can dried forms using of the Shinkansen coating method of paper.
Purpose of the present invention is a kind of plastic polymer pigment of can dried forms using, a kind of method of producing this plastic polymer pigment of can dried forms using and a kind of application of plastic polymer pigment in the dry-coated method of paper or cardboard of can dried forms using.In addition, another object of the present invention is a kind of by the method for ion injection usefulness dry-coated paper of polymer pigment or cardboard and through dry-coated paper or cardboard.
Claims have provided the application in the dry-coated method of paper or cardboard of the performance characteristic of the plastic polymer pigment of can dried forms using, the plastic polymer pigment can dried forms used, have sprayed method and dry-coated paper of the present invention or cardboard with dry-coated paper of polymer pigment or cardboard by ion.
The present invention finds, paper and cardboard can be with dry-coated method coatings, wherein the plastic polymer pigment can dried forms used of use.Plastic polymer pigment can preferably use the spray drying technology drying with suitable method, obtains segmenting pigment powder.Suitable polymers pigment is based on the plastic pigment of polystyrene, polyacrylic ester and polymethacrylate, poly-(cinnamic acrylic ester) multipolymer at least, based on plastic pigment or its combination of melamine-formaldehyde and urea-formaldehyde.Plastic pigment is the water dispersion drying of 1-85% weight, preferred 5-60% weight by dry matter content.The particle diameter of plastic pigment to be dried is the 10-2000 nanometer, preferred 150-1000 nanometer.About surface tissue, plastic pigment to be dried is a hydrophobic or hydrophilic, and it can comprise the various reactive groups that can carry out modification to its performance.The tap density of plastic pigment to be dried is the 100-2000 grams per liter, and its second-order transition temperature is 80-160 ℃.About its structure, plastic pigment can be a hollow or solid.By the raw material monomers of the different amounts of polymerization, can control shell hardness, softening temperature, cohesive force, wear resistance, printability, also have the material cost of granules of pigments certainly.The dry drying means that adopts any suitable generation drying and fully segment pigment powder preferably utilizes spraying drying to carry out.In the spray drying process of routine, polymeric dispersions is drawn in the nozzle of cyclonic separator.Nozzle can be static or rotation, and dispersion wherein is that 150-250 ℃ warm air heats rapidly by temperature.This dispersion is blown into cyclonic separator subsequently, wherein forms drop and vaporize water immediately simultaneously.Usually, the temperature in the cyclonic separator is about 80-100 ℃.In the container of cyclonic separator, collect the dried pigment powder.Any suitable spray drying unit all can be used as spray-dryer.
The performance of plastic pigment can be carried out modification by several modes of chemistry and physics.By regulating the molecular weight distribution of plastic pigment, can control its rheological property, comprising:
A) viscosity in the softening range,
B) can reduce the infiltration and prevent excessive flow elasticity and
C) influence the degree of crosslinking of elasticity and viscosity.
The rapid heating of this drying coated method and compression step also produce useful influence to the rheology and the thermal characteristics of plastic pigment.The thermotolerance of plastic pigment can preferably be improved by melamine-formaldehyde or urea-formaldehyde treated, and melt temperature can be improved, and resistance to pressure can be improved, and reinforced performance and printability can be regulated as required.
Solid and liquid adjuvants and additive can be before spraying dryings and are added dispersion in some cases even afterwards.The additive that the reagent of pelletizing additives, tackiness agent, white dyes, latex, improvement electrical property and other are usually used in paper and cardboard can add this dispersion.Suitable pelletizing additives comprises carboxymethyl cellulose (CMC), polyvinyl alcohol (PVA), styrene butadiene latices (SBS), polyethylene wax (PE), and the appropriate amount of additive is the 0.5-5% weight of this dispersion.Suitable paint adhesion agent comprises SBS and PVA.Suitable additive can be used for improving the brightness of paper or cardboard.Microbicidal additives can be used for making antibiotic paper or liquid packaging cardboard.In addition, can use inorganic additives such as kaolin, talcum, titanium dioxide, satin white, precipitated chalk (PCC), pulverize lime carbonate (GCC) or analogue, advantageously influence the performance of plastic pigment, comprise its chemistry, physics, printing and economic performance.These additives also can be used for regulating reinforced, the bonding of plastic pigment and powder performance and with this transportation of materials with the handling property when transferring to apparatus for coating.
Same as before or the drying that is combined with the plastic pigment of additive obtain the segmentation pigment particles aggregate body of dried forms, its particle diameter is 1-500 μ m, dry matter content is 85-100%.These pigment particles aggregate bodies are made up of single spherical granules of pigments, and they bond together by electrostatic force.These particles can be hollow or solid.
In addition, the dry plastics pigment powder can randomly be handled with refiner, and wherein structure is partly pulverized, thereby increases porosity and opacity.By in the superpower refiner, handling dried pigment, changed the electrical property of this pigment, this influences the bonding of pigment and paper web.
The advantage of dried plastic polymer pigment comprises easy transportation and storage, and the heatproof degree changes.
Plastic pigment for example influences following printing performance:
A) printing quality is improved, because gloss and slickness improve and are more even on whole surface,
B) plastic pigment helps the sedimentation and the stability of printing-ink, because should the surface not be that porous and printing ink can not infiltrate paper too deeply,
C) because plastic pigment particulate surface is not a porous, printing-ink can not spread too much, or form fuzzy profile and
D) plastic pigment has been arranged, can enough be used to the surface strength of printing.
Hollow structure is created in the particle elasticity under the compression, and therefore in press polish or similar ornamenting step and bonding process, its middle layer of the surface ratio of coating is pressurized more.In addition, the particulate hollow core is given coating with opacity, has improved the ability of scattered light, and wide particle diameter distributes and to cause intensive filling, so the opacifying power excellence.The optical property of product depends on size, shape and the topology of granules of pigments and distributes, can regulate gloss, slickness, opacity, brightness and opacifying power like this.In addition, the polymer pigment that stores with dried forms is not subject to microbial contamination, for example bacterial contamination, and this is different from existing water dispersion.If pigment be shaped as sphere, particle can not damage its hollow structure when pressurized.Be adjusted to 1.3-1.65 by the refractive index with plastic pigment, preferred 1.6-1.65 can obviously depart from the specific refractory power (being 1) of air, has improved scattering force like this and the brightness with little blue cast is provided.By regulating the hollow volume is 10-80%, and corresponding effects can be provided.Because drying process is fast, the particulate surface property does not change when being exposed to high temperature of short duration.Spraying drying can change the particulate electrical property, has promoted the formation of aggregate like this.It is reinforced more even that pigment ratio with narrow size distribution has the pigment that wide particle diameter distributes.Hollow pigment generally increases the deflection of paper or cardboard, and their opacifying power height.Therefore plastic pigment has improved the slickness of its cohesive action and coating also as the binding agent of mineral dye.The hollow aggregate structure of plastic pigment is stayed in the coating, and wherein plastic pigment has increased the cohesive force of other coated material.Plastic pigment can be by gathering that prevents mineral constituent and the opacity of improving the coating blend by this pigment of uniform distribution.The structure of plastic pigment particle and aggregate and big scattering area help being keeping in the coating high opacity and enough brightness.Under the situation of plastic pigment, the amount of the polymkeric substance that is used as tackiness agent that the known pigment volume is required is lower.Plastic pigment has been arranged, and the tone of coated product can be regulated as required.
Plastic pigment can be considered the additive as ornamenting paper surface, because they make surface modes adjustable.That is, the non-required compressive action of paper base material under pressure descends.
Except obtaining high loosing character and deflection, the weight of White Board can have more low-density pigment by use and descend.By providing required coat-thickness by light layer, the proportion of fibers of paper base material can correspondingly descend, and has improved the intensity of paper like this.Therefore, the paper that scribbles plastic pigment is lighter than conventional paper.
Because obtain high-quality surface under the reason temperature and pressure of lower, the wearing and tearing of rolling press cylinder are less.The efficient of apparatus for coating can correspondingly improve by gathering way.
In addition, the advantage of segmentation plastic pigment coating is that its film forming latex than prior art after thermal treatment and bonding shrinks little.
The various traditional methods that are used for the paper conversion technology can substitute with this new dry-coated method, wherein use the polymer pigment of selecting according to occasion of can dried forms using.
In addition, compare with conventional mineral dye, the plastic polymer pigment of can dried forms using is being used for providing several advantages when dry-coated, comprise that plastic pigment is softening down at about 100-120 ℃, therefore the plastic pigment of being used is bonded on the paper base material in burnishing process well, because press polish is carried out on the second-order transition temperature of plastic pigment usually.Since this softening, need not extra binding agent.If desired, the composition of coating can obtain various plastic pigments so as required by use other additive and component to regulate with plastic pigment.In addition, the performance of plastic pigment can be carried out chemical modification and adjusting as required.The paper that scribbles plastic pigment can reclaim by burning, because it does not contain any not flammable inorganic substance, or plastic pigment can chemical separation from paper.
The present invention is existing to be illustrated by embodiment, and has no intention to limit its scope.
