Definitions
- the present invention relates to melt-processed products of dialcohol cellulose and a method of preparing the products.
- the present invention facilitates the preparation of extruded and/ or injection molded products having high cellulose content.
- the present invention relates to a material comprising cellulose fibers wherein the cellulose fibers are at least partly modified into dialcohol cellulose and wherein the material have absorbed 5-40wt% moisture or water. All the embodiments disclosed herein relates to all the aspects unless stated
- the mechanical properties may be tailored by varying the type and amount of the second polymer and/ or by changing the degree of modification. For example by increasing the content of the modified cellulose when mixed with a soft polymer, such as EAA, the obtained material showed an increase in the elastic modulus and the yield strength significantly.
- a soft polymer such as EAA
- the material When the material is injection molded it may first be compounded in a separate extruder or it may be added to the injection molding apparatus directly optionally together with the optional second polymer and the optional additives.
- the injection molding may be one step in a production line where the product is injection molded directly into place, so called in-line injection molding.
- the melt-processing is done at a temperature suitable for the specific material composition, depending on the glass transition temperatures and/ or the melting temperature.
- injection molding may be done at a temperature of 100- 150°C such as 120-130° C for a material comprising modified cellulose fibers and poly (ethylene acrylic acid) . If the cellulose has an increased moisture content, the temperature can be lowered.
- Handsheets with an approximate grammage of 150 g m -2 were prepared using tap water in a Rapid Kothen sheet former (Paper Testing Instruments, Austria). The sheets were dried at 93°C under a reduced pressure of 95 kPa. The sheets were then stored at 23°C and 50% RH until further testing/use.
- Example 4 Processing conditions of dialcohol-cellulose-fiber (hereafter called fiberX, where X denotes the degree of modification) -based composites.
- DSM Micro compounder 5 ml MC 5 (DSM, Xplore Instruments BV, The Netherlands) Thermo Scientific HAAKE MiniJet Pro - Thermo Fisher Scientific
- Example 1 and 2 Materials obtained in Example 1 and 2 were used to prepare injection molded products. Composites with different fiber and EAA content were prepared as well as 100% fiber product. The different contents are seen in tables 1 to 4.
- Ta peak value of loss modulus (E"); Damping factor as peak value of tan delta; Storage Modulus ( ⁇ ') at -20 °C and at 25 °C (RT).
- Table 1 Table over force needed during injection molding of material containing different amounts (10-90wt%) of dialcohol cellulose.
- Table 3 Table over mechanical properties of materials containing different amounts of dialcohol cellulose.
- Table 4 Table over mechanical properties of materials containing different amounts of dialcohol cellulose.
- the materials were either extruded (compounded) dry or wet (RH90%) at 120°C or 80°C at 30 or 60rpm and injected. The injected samples were then dried at 105°C for 2 hours. The stress-strain measurements were conducted using an Instron 5944 at 23°C and 50% RH. Table 5. Table over force needed during compounding (extrusion) of material containing 100wt% of Fiber 55- dry and wet samples and wet Fiber 38.
- high cellulose fiber content material may be extruded and injection molded at a reasonable temperature without the addition of any additive such as plasticizer or compatibilizer. Furthermore, the obtained material also has good mechanical properties. Example 5.
- the cooled product was placed in the reactor and NaBH 4 (350g in around 2 liter of water) was added during 3 minutes. The temperature was monitored to avoid temperature above 10°C. Stirring was continued for 1 hour and the reaction product was emptied from the bottom of the reactor. The reaction product was filtered using filter bags (FSI filter size 2) and was quickly washed with deionized water to remove remaining NaBH 4 . The product was washed until the wash water conductivity was less than 10 ⁇ S/cm . The filtered and washed product was dewatered using a mechanical screw press to a dry content of 10- 15%.
- FSI filter size 2 filter bags
