Example 1: Melamine-urea-formaldehyde (MUF) resin with traditional acid hardener and t-melamine-urea-formaldehyde (MUF) resin, phenol-resorcinol_formic acid (prf) tree and acid Testing of adhesive systems with low formaldehyde emissions. For each adhesive system, the emissions from the bonded structure were tested according to JAS MAFF992. Two sets of bonded structures are made for each adhesive system. Five spruce veneer sheets (135 x 150 x 29 millimeters) were assembled and a mixture of a resin and a hardener applied in an amount of 400 g / m 2 was bonded. After embossing and conditioning (at a relative humidity of 200% 65%), two pieces of 75x150x135 mm were cut out. The joint end (facing the fiber) was closed in Lu province, leaving only two 75 × 150 mm surfaces with exposed adhesive lining. The two sides of the adhesive structure with the exposed adhesive lining were planed 200422157 flat, and for one structure of each adhesive system, the two planed sides were sprayed with 40% by weight urea and An aqueous composition of 7% by weight of polyvinyl alcohol was used for treatment, but the other structure was not treated. Each element was placed in a 40 liter dense chamber with a beaker with water as a sampler. The formaldehyde emissions (expressed in mg / L) of all structures in the water sample were determined according to the test method and are shown in Table 丨.

Example 2: Test the same U-amine-urea-urea-formaldehyde (MUF) resin as the one used in Example 1 and a conventional acid hardener. According to the modification, the smaller test method is used, and the internal test method of JAS MAFF992 of type 5 element is used to test the emission of formaldehyde from sticky 钍 f σ, ,, and ° structures. Five spruce sheets (5x150x150 milli-half, as known from the pen wood) were assembled and coated with resin and hardener in an amount of 380 g / m2.合物 This compound is bonded. After embossing and conditioning (at 20 ° C, 65% relative, itch, and 盘 pair humidity), two pieces of 75x25x10 mm were cut. The joint ends (face-to-face, and the fiber direction) were closed with aluminum foil, leaving only two pen surfaces with exposed adhesive linings. 15 200422157 Two sides of the two elements with exposed adhesive linings are planed, pieces, — T five elbow one yuan 'fine by spraying on its two planed sides with a 40% drum to Here, A bed is two / 0.07% by weight of an aqueous composition of polyvinyl alcohol for treatment.
