Definitions

the structure of such a laminate consists of several layers which are connected to one another over a large area and which consist of the same or different materials to fulfill special functions and properties.
core paper is used as one of these layers in the production of decorative paper laminates.
These layers are usually bonded by pretreating the individual layers, such as prior impregnation and subsequent pressing of the layers in the stack under pressure and temperature.
the present object is achieved by the method according to the invention for producing a core paper.
the core paper consists at least of a portion of a recycled fiber mixture and a wet strength agent as the first additive. This is marked Core paper through the addition of a surface-active substance as a second additive in manufacturing, to increase capillarity.
Laminatable in the sense of the present invention are understood according to the Latin word "Lamina” in the meaning of "layer” to mean all types of combining different layers of material.
carrier material refers to layers of material on which or under which one (or more) further layer (s) can be laminated. Laminates are often referred to as layered composites.
Recycled fibrous material in the sense of the present invention is understood to mean all types of fibrous materials which are recycled for the production of paper, cardboard and cardboard, in particular core paper, and which are used in the production of paper, cardboard and cardboard, in particular core paper.
these types of waste paper are determined in accordance with the CEN European Standard EN 643.
wet strength agent is understood to mean all additives which increase the strength of paper, cardboard, cardboard and core paper, inter alia, in the wet state.
wet strength agents connect the fibers at the points of contact and intersection. If the paper is now damp or wet, as a result of which the hydrogen bonds and thus the strength are lost, the wet strength agent keeps some of the strength in the wet state of the paper.
the wet strength is determined, for example, by the tensile load of a wet one Paper strip in a tensile testing machine, which leads with constant feed until the wet paper strip breaks.
the use of wet strength agents is necessary in all areas of application in which paper becomes wet or very moist, such as in the area of hygiene or decorative paper.
wet strength is a basic requirement for the impregnation resin impregnation step, in which the paper web is guided through a liquid bath.
Many wet strength agents or wet strength agents have to condense and polymerize in the paper structure. This takes place only in part in the dryer section of a paper machine. A ripening or maturing time is usually necessary to fully develop the wet strength.
surface-active substance is understood to mean all types of substances which reduce the surface or interfacial tension between two phases.
An interface is the area between two immiscible phases.
one speaks of a surface if one of the phases is a gas, such as air.
the phase boundaries can be characterized by interfacial or surface tension, which describes the effort to reduce the interface.
surface-active substances are also referred to as wetting agents, detergents (surfactants, soap) or emulsifiers. Such substances are distinguished by their polar structure in that they preferentially accumulate at the interfaces of a disperse system.
Atro is understood to be absolutely dry. Atro is often referred to as otro (oven-dry). This term is the benchmark for measuring the dry content of paper and pulp. The determination is carried out, for example, according to the standard: BS EN ISO 638 paper, cardboard and fibrous material - determination of the dry matter content - warming cabinet method. Conventionally, dosing quantities of additives on the dry substance are calculated.
the proportion of recycled fiber mixture is greater than 25%, furthermore greater than 40 and 100%, preferably between 50 and 95%, particularly preferably between 70 and 90%, preferably in the range of 75%, particularly preferably over 80 %, very particularly preferably over 95% and in particular up to 100% and in particular the fibrous material is selected from a group which, for example, kraft pulp and / or kraft liner, in particular department store waste made from corrugated cardboard and cardboard with at least 70% corrugated cardboard and remnants of solid cardboard and / or Packaging paper, used corrugated cardboard boxes, chips from unused corrugated cardboard with layers of kraft or test liner, used corrugated cardboard with kraft liner and / or corrugated material on cellulose and / or thermo-chemical pulp, used corrugated cardboard with layers of test or kraft liner and at least one layer of kraft liner , used sacks made of kraft pulp wet Eat-proof or not wet-tear proof, unused sacks made of kraft pulp wet
the strength parameters can be differentiated between static and dynamic strengths.
Static strength is the force that a paper can withstand under slow and even tension.
Static strength parameters include, for example, breaking strength, breaking length, elongation at break, and modulus of elasticity.
Dynamic strength is the force that a paper can withstand under rapid and / or uneven tension loading.
the dynamic strength parameters include, for example, specific tear resistance, burst strength, double fold number (kink resistance). Examples of general paper properties are paper smoothness, porosity, roughness, air permeability, formation, rigidity, flatness and opacity.
the wet strength agent is selected as the first additive from a group which in particular compounds of epichlorohydrin resins, urea, melamine-formaldehyde resins, phenolic resins, acrylic resin dispersions, synthetic resin dispersions based on acrylic acid esters and / or styrene-butadiene, polyurethane, Polyolefin dispersions, polyamidoamine resins, polyamidamine-epichlorohydrin resins, combinations thereof, and the like.
the surface-active substance is selected as a second additive from a group which has compounds which accumulate particularly strongly at interfaces. According to their functional chemical groups, the additives are divided into bifunctional, anionic, nonionic and cationic compounds.
the characteristic feature of all surface-active substances is their polar structure, mostly due to at least one lipophilic hydrocarbon residue and at least one hydrophilic functional group, as a result of which they preferentially attach to the interfaces of a disperse system.
anionic surfactants are, in particular, soaps, linear alkylbenzenesulfonates, alkanesulfonates, alkyl sulfates, alkyl ether sulfates, fatty alkyl polyethylene glycol ether sulfates, fatty alkyl sulfates.
nonionic surfactants are, in particular, fatty alkyl polyethylene glycol ethers, fatty alcohol ethoxylates, fatty acid condensates, ethylene oxide / propylene oxide copolymers (EO / PO), alkylphenol ethoxylates, sorbitan fatty acid esters, sorbitan mono- (di, tri) laurate, oleate, palmitate, stearate, sorbitol, polysorbate, polysorbate, polysorbate, polysorbate, polysorbate N-methylglucamides, alkylphenol polyethylene glycol ethers, fatty alcohols, oxo alcohols, Ziegler alcohols, alkylphenols and ethylene oxide.
fatty alkyl polyethylene glycol ethers fatty alcohols, oxo alcohols, Ziegler alcohols, alkylphenols and ethylene oxide.
cationic surfactants are, in particular, quaternary ammonium compounds with hydrophobic groups, salts of long-chain primary amines.
surface-active substances are polyelectrolytes, emulsifiers, wetting and dispersing agents, fountain solutions and polysaccharides, in particular sorbitol.
the aqueous fiber suspension is also referred to as the so-called finished product.
the basic core paper is produced with the paper machine process steps of dewatering / sheet formation, pressing, drying, possibly smoothing and reeling. After the necessary maturation time, in which the final wet strength is reached, the core paper is ready for the impregnation process step.
the core paper web is passed through an immersion bath and impregnated with a resin.
the core paper produced with the method according to the invention can be used as a material component in composite materials, in particular layered composite materials, in particular compact boards (sometimes with a thickness of up to 10 mm), fiber composite materials, particle composite materials and penetration composite materials. This covers the use of the core paper for all geometries of the composite.
core paper in the basis weight range from 40 to 400 g / m 2 , preferably in the range between 140 to 300 g / m 2 , particularly preferably between 150 to 250 g / m 2 , very particularly preferably over 150 g / m 2 , conventionally used Kraftliner virgin fiber, in particular also kraft pulp used.
the fresh fiber pulp comes from an upstream pulp production, so that no drying steps of the fibrous material are interposed, which means, in particular, that the pulp is not horny.
the cornification of the pulp has Influence the surface properties of the fibers and can have a negative impact on strength properties and the capillarity or absorbency of the finished core paper.
