Description
Technical field
The present invention relates to plank adhering technique field, in particular to a kind of novel timber adhesive and its preparation side
Method.
Background technology
The species of wood adhesive is a lot, wherein prevailing is urea-formaldehyde resin adhesive, phenolic resin glue and melamine
Amine-formaldehyde resins glue, there is Form aldehyde release.Formaldehyde can discharge during the production of plywood and use；The acquisition time of formaldehyde is long
Up to 3-15 years, can not possibly vapor away completely in 1-2 years after finishing, so as to cause formaldehyde content in indoor air exceeded for a long time,
The healthy of people is worked the mischief.The characteristic of urea-formaldehyde glue determines that it can release free formaldehyde in production process of plate,
And the content of formaldehyde in glue is reduced merely while also reducing bonding strength, therefore many sheet material manufacturers are aborning, greatly
Take passive formaldehyde more and the means such as shelter, adsorb, closing, be typically only capable to reach E2, E1 level mark in the burst size of formaldehyde
Standard can reach reluctantly E0 level standards, once possessing the condition of formaldehyde volatilization, this part formaldehyde still can volatilize in a large number.Some
Although without Form aldehyde release, its hot water resistance is not also very strong to no-formaldehyde adhesive.
The content of the invention
The invention provides a kind of novel timber adhesive and preparation method thereof, the present invention can be used for bond timber, gluing

Step 3, add surplus stock fully dissolve or disperse step 2 gained, make wood adhesive.
The invention has the beneficial effects as follows：
1st, almost without Form aldehyde release during the present invention is in production and using the process process of wood-based plate (production), to workman and disappear
Expense person is not resulted in by Health cost caused by formaldehyde；
2nd, there is higher resistance to water with the plywood of the wood adhesive gluing of the present invention.Can be used to produce II classes
Plywood and Group III plywood；
3rd, product of the invention can be stored at room temperature, and without the need for cold preservation, long shelf-life was up to 1 year.And urea-formaldehyde resin adhesive is cold
Effect duration under the conditions of Tibetan is only 6 months or so.
