Description
Technical Field
The invention relates to the technical field of industrial glue, in particular to a curing method of industrial glue.
Background
The phenolic aldehyde (PF) resin has better bonding strength and excellent weather resistance after being cured, and is a common adhesive in industry. However, PF glue has the disadvantages of darker color and higher curing temperature. The PF glue can be cured and crosslinked only by hot pressing at the temperature of 130-150 ℃, so that better bonding strength and wood failure rate are generated. When the hot pressing temperature is less than 130 ℃, the bonding strength can be ensured only by a method of prolonging the hot pressing time and reducing the production capacity. Therefore, in practical operation, it is difficult to ensure the curing speed of the PF glue, resulting in low curing efficiency and increased defective rate of products.

In order to solve the technical problems, the technical scheme of the invention is as follows:
A solidification method of industrial glue, take a certain amount of phenol and formaldehyde to carry on the condensation polymerization, and add catalyst; adding a formaldehyde trapping agent after the polycondensation reaction is finished, thereby preparing the environment-friendly PF glue; curing agent with the concentration of 5% -10% is added into the prepared environment-friendly PF glue.
Preferably, the catalyst is one or a combination of divalent metal ions and monovalent metal ions.
Preferably, the catalyst is any one or more of Mn 2+, Ca 2+, Zn 2+ and Mg 2+.
Preferably, the addition of formaldehyde is completed within half an hour during the polycondensation reaction.
preferably, the curing agent is prepared by mixing a succinic acid ester compound, a glutaric acid ester compound, an adipic acid ester compound, an acetic acid ester compound and an ether compound according to the proportion of 8:4:4:7: 2.
