Test result
Utilize the urea-formaldehyde glue tackiness agent of the embodiment of the present invention 1 to embodiment 4 method acquisition and the urea-formaldehyde glue tackiness agent that reference examples method obtains, that according to method in GB/T14074-2006, measures tackiness agent is solid containing indexs such as, pH, viscosity, set time, water-soluble, shelf liveves, according to the method in GB/T18883-2002, measure airborne formaldehyde content in urea-formaldehyde glue tackiness agent making processes, result is as shown in the table:
Table 1
As shown in Table 1, the solid content of embodiment 1 to 4 will be apparently higher than reference examples, simultaneously water-solublely will be worse than reference examples, and suitable with reference examples aspect set time and storage stability.Therefore, meeting under the prerequisite of glue performance and product stability, the present invention can obviously improve the perviousness of urea-formaldehyde glue tackiness agent, meanwhile, in embodiment 1 to 4 urea-formaldehyde glue making processes, formaldehyde content is all lower than 0.1mg/m3, lower than GB/T18883-2002 specified standards value, and in the glue process of reference examples, the formaldehyde volatilizing can stimulate eyes, cause and shed tears.
Test example
Utilize the urea-formaldehyde glue tackiness agent of the embodiment of the present invention 1 to 4 method acquisition and the urea-formaldehyde glue tackiness agent of reference examples acquisition to produce respectively 3 layers of glued board test specimen 1,2,3,4,5; Veneer is the veneer of grey olive processing, and water ratio is 6-12%;
The preparation of pre-pressing process condition and test specimen: Amount of spread 400g/ ㎡ (two-sided), preload pressure is 20-25MPa, the time is 60 minutes.
Heat pressing process is, pressure is 140-150MPa, temperature 120-140 ℃, and the time is 30-50s/mm.
According to GB9846-2004, the slab saw solution suppressing is become to standard specimen, with omnipotent mechanical test machine, measure the bonding strength of slab, test result is as shown in the table:
Table 2
| Numbering | The bonding strength of slab after precompressed | The bonding strength of slab after hot pressing |
| Embodiment 1 | 0.62 | 2.08 |
| Embodiment 2 | 0.58 | 1.95 |
| Embodiment 3 | 0.64 | 2.12 |
