Definitions
- the invention relates to a method for producing a pre-impregnate, with the Process obtained pre-impregnate and its use for the production of decorative composite structures.
- the invention further relates to those for impregnating the pre-impregnate used impregnation fleet.
- WO 94/00523 discloses an aqueous impregnation solution with which papers are impregnated which are then used to manufacture laminate panels.
- the aqueous impregnation solution contains 5 to 90 parts by weight of polyvinyl alcohol to 10 to 95 parts by weight of one Dispersion of an ethyl styrene / acrylate / burylacrylate copolymer.
- the state of the art has been a pre-impregnation through sales since the late 1980s known that by impregnating a base paper from a cellulose long and Short fiber mixture with an impregnation liquor known under the internal name R20 is obtained.
- This impregnation liquor contains 15% of a glyoxal / urea precondensate or resin in aqueous solution, 57% of a 50% aqueous dispersion of a copolymer based on n-butyl acrylate and styrene and 28% water.
- This Preimpregnate has various desirable properties, such as. B.
- the invention was therefore based on the object of providing a prepreg that all has desirable properties of the pre-impregnate described above, at the same time but shows no tendency to yellowing.
- this object is achieved with a method which is characterized in that is that a base paper is impregnated with an impregnating liquor which a) a aqueous dispersion based on an acrylic acid ester / styrene copolymer. b) a dry strength agent based on a copolymer of (meth) acrylamide and (meth) acrylic acid and c) contains water, with per part by weight of dry copolymer (Meth) acrylamide and (meth) acrylic acid about 0.3 to 13 parts by weight of dry acrylic acid ester / styrene copolymer be used.
- pre-impregnate is a term known to the person skilled in the art technicus.
- the pre-impregnate is, as mentioned above, by impregnating one Obtain base paper with an impregnation liquor. Then it is dried. It lies then in the form of a resin-impregnated fiber material - in technical terms also foil called - before and is brought to the market. Depending on the desired end use it can be modified further.
- copolymer (Meth) acrylamide and (meth) acrylic acid about 1 to 9 parts by weight, in particular about 3 to 7 parts by weight, acrylic acid ester / styrene copolymer can be used.
- the latter Area leads to the advantage that it is low in formaldehyde, flexible and resistant to yellowing Product is received.
- the pH of the impregnation liquor used is preferably in the range of about 4.5 to 8.0, especially in the range of about 5.0 to 5.5.
- the setting of the desired pH can be adjusted with sodium hydroxide solution and sulfuric or hydrochloric acid. Too high a pH can cause instability of the dispersion, a too low pH can under certain circumstances act fiber damaging.
- the viscosity (measured according to DIN 53211) of the impregnation liquor should be about 10 to 18 seconds, in particular be about 11 to 14 seconds.
- the solids content of the impregnation liquor is in the range of about 15 to 50% by weight.
- a solids content of about 30% by weight is preferred because of this a desirable degree of impregnation of the nonwoven is achieved.
- the acrylic acid ester of the acrylic acid ester / styrene copolymer can be methyl, Act ethyl, n-butyl, i-butyl and 2-ethylhexyl ester, the use of n-butyl acrylate is preferred.
- Acronal S 305 D® is one 50% aqueous dispersion of a copolymer based on n-butyl acrylate and styrene.
- the acrylic acid ester / styrene copolymer is in the form of a film.
- the Minimum film formation temperature is preferably in the range from about 5 to 70 ° C. especially in the range of about 10 to 30 ° C.
- the dry strength agent is preferably a copolymer of acrylamide and acrylic acid with an anionic charge. Compared to a dry strength agent Based on a copolymer of methacrylamide and methacrylic acid with an anionic charge the use of a copolymer based on acrylamide and acrylic acid leads to less brittle products.
- the dry strength agent itself has a solids content of about 15 to 30%, in particular from about 20 to 22%, a pH in the range from about 6.0 to 9.0, a viscosity from about 100 to 300 mPa.s (Brookfield; 20 ° C) and a density of about 1.0 g / ml 20 ° C.
- the dry strength agent is intended to be used in the pulp in order to to develop properties described below. Because the dry strength agent Forms polymer bridges, it solidifies the paper structure without disturbing the sheet formation or affect the porosity. This means that all mechanical Strength properties of the paper can be improved. Depending on the amount used and paper type, improvements in tear length and burst strength are achieved as well the tear strength and the splitting strength of the paper. This allows, depending on Quality requirements, the use of inexpensive raw materials, a higher ash content of the base paper and the saving of tools. One shows as a side effect significant improvement in retention.
- Long and short fiber pulps can be used as fiber raw materials.
- the material input of the pre-impregnated base paper does not differ significantly from that of the Decorative papers.
- the long fiber content is approximately 0 to 40%, in particular approximately 15 to 30%, the short fiber content about 60 to 100%, in particular about 60 to 85%.
- the grind of the Base paper is also variable and is between about 18 and 50 ° SR, in particular between 25 and 35 ° SR.
- the ash content of the base paper depends on the paper used between about 2 to 40%, in particular between about 10 to 30%. The settings in the paper machine, such as. B.
- property-modifying additives such as. B. pH regulator, Wet and dry strength agents, synthetic resin dispersions, precipitants (fixing agents), Surfactants, dyes, fillers, hardening, viscosity regulation, non-stick and Penetration aids and pigments to add to the impregnation solution.
- the impregnation of the base paper to the pre-impregnate is done with a paper impregnation system carried out.
- a paper impregnation system carried out.
- Machine parts such as unwinding, size press, dryer section, steam humidifier, smoothing value and paperoller rewind.
- the pre-impregnate can be used either according to the so-called “on-line” or the “off-line” procedure getting produced.
- "On-line” means that the size press with which the impregnation liquor is applied, arranged in the paper machine, while under To understand “off-line” is that the size press in a separate operation behind or after the paper machine is used. In the latter case, the prepreg is at the end the paper machine not as a finished product but as a semi-finished product. this leads to important parameters such as color, porosity, smoothness and the final basis weight, either reproduced in the laboratory or calculated back from experience Need to become.
- the impregnation liquor can be applied to one side but also to both sides of the base paper become. If the impregnation liquor is applied to one side, then the training is the surface of the screen side of the base paper is important, for which a control of the Temperature curve of the predrying group of the paper machine is extremely important. At impregnation on both sides, the impregnation can take place completely, d. H. she can in penetrate the entire mass of paper.
- the total intake amount of impregnation liquor through the base paper depends on the type of base paper, but also that of Pressing off the excess impregnation liquor from the paper web.
- the pre-impregnate according to the invention has the advantage that the processing products do not turn yellow when applied leads. This is due to the fact that the component of the glyoxal / urea precondensate by a dry strength agent based on a copolymer (Meth) acrylamide and (meth) acrylic acid with a weakly anionic charge was replaced.
- a dry strength agent based on a copolymer (Meth) acrylamide and (meth) acrylic acid with a weakly anionic charge was replaced.
- the Dry strength agent is usually used in bulk and physically leads to a fiber consolidation, which improves the dry strength in the end product, not against it the wet strength. This shows that the dry strength agent is only physically fiber adhesive acts and the fiber structure is not solidified by chemical reaction.
- the pre-impregnate according to the invention can be used for the production of decorative composite structures become.
- decorative laminates with the invention Pre-impregnated. They are applied using heat and pressure as well as suitable glue systems in presses or laminating plants.
- chipboard and medium density fibreboard (MDF) on both sides with the coated according to the invention.
- the pre-impregnate also serves as decor-bearing component.
- Wood-based materials are also used extensively in the manufacture of furniture of chipboard used. The often unsightly surface of these wood materials and their limited use value require the use of coating materials.
- the prepreg according to the invention is suitable for this.
- the invention Foil can have any wood grain or any fancy decor.
- In the pre-impregnate can be varnished in a further step.
- transparent paints such as. B. acrylic paints acid-curing, water-soluble and pigmented paints. In addition to the protective function of the lacquer, this gives the pre-impregnate also a corresponding visual impression.
- a base paper of the following composition was produced: 20% pine sulfate pulp and 80% eucalyptus pulp. The freeness was 31 ° SR (Schopper-Riegler). 30% titanium dioxide and 4% were added (on otro pulp) formaldehyde-free wet strength agent used.
- This base paper with a weight per unit area of 50 g / m 2 was impregnated on both sides with the impregnating liquor according to the invention in a 7: 1 ratio in a size press, the necessary solids content being set with water.
- the dispersion alone has poor splitting resistance shows.
- the dry strength agent alone has insufficient water resistance and tends to poor splitting resistance.
- the impregnation liquor according to the invention leads to good ones Water resistance and sufficient splitting resistance, as well as formulation 4.
