| abstract | The invention relates to the production of glue, in particular for glueing. "The invention relates to the production of glue, in particular for glueing plywood. The aim of the invention is to reduce the curing time of the glue and reduce the duration of the gluing of veneer during the manufacture of plywood. The glue is prepared in a mixer by successively introducing into a water-soluble phenol-formaldehyde resin of a resol solution with constant mixing. Phenolorezor-formaldehyde resin and sodium carbonate for 30 minutes. Filler (chalk) can also be added to the glue. The compositions of the known and proposed adhesive (examples 1-3) and control examples (4-7) are given in table. 1, their physico-chemical properties in the table.2. Using the proposed adhesive, plywood 8 mm thick is made of vanilla plywood. The invention makes it possible to reach the curing time of the glue at 105 C for 6.1 minutes and to reduce the duration of the gluing of the veneer to 5.5 minutes while retaining the strength when splicing the plywood over the adhesive layer after boiling in water for 1 hour at the level of 1.4-1. 6 WA. The effect is achieved by using an adhesive based on 100 mash. water-soluble phenol-formaldehyde resin rezol type as a resin on the basis of resorcinol 3-5 wt.h. phenol-resorption-formaldehyde resin; and as a basic compound, 5-12 wt.h. sodium carbonate. 3 tab. from birch veneer with a thickness of 1.5 mm, humidity 5-7%, format mm. Gluing modes: temperature of press plates 120-125 ° C, pressure 2 MPa. The adhesive consumption for all variants is the same and is 110-115 g / m. In tab. Table 3 shows the results of testing samples of plywood for durability when splicing on the adhesive layer after boiling for 1 hour. According to the aforementioned GOST, the strength of FSF plywood should be at least 1.4 bffla. The proposed glue reduces the gluing time of the veneer while maintaining the strength of the plywood at the required level. The formula of the invention Clay, including water-soluble Phenol-formaldehyde resin rezol i W with 4 f O9 S |
