Abstract
The invention discloses a method for improving the open time of a phenolic resin adhesive, which comprises the steps of diluting and dissolving polyhydric alcohol by using deionized water, and uniformly stirring; adding the cellulose ether into the first step, slowly heating to 50-60 ℃, and stirring until the cellulose ether is completely dissolved; cooling to normal temperature, adding xanthan gum for dissolving, and finally adjusting the solid content of the solution to 45%; adding the prepared solution into an adhesive to finally obtain the adhesive with longer open time. The method disclosed by the invention is simple to operate and has an obvious effect. The uniformity of the cellulose ether in the solution can be improved by adding the polyalcohol into the adhesive, and the water retention of the adhesive can be improved to a certain extent by adding both the cellulose ether and the xanthan gum.

Background
Plywood is an important component of the artificial board industry, and in 2019, 1.92 billion cubic meters of plywood produced in China accounts for 63.9 percent of the consumption of all artificial board products. The growth rate is 16.4 percent on the basis of 2018 years, and the artificial board is the board with the fastest amplification rate in the artificial boards.
The wood adhesive is a key core technology of the artificial board industry, wherein the phenolic resin adhesive accounts for the main component. The phenolic resin adhesive has obvious advantages in the board industry, and phenolic resin molecular chains can form a three-dimensional net-shaped structure when being cured, so that the board has excellent waterproofness and good strength, and therefore, the phenolic resin adhesive is used for boards with high requirements on waterproofness.
Phenolic adhesives offer advantages but also suffer from such problems during use. The short open time of a phenolic resin adhesive is a problem which is always accompanied, and the short open time means that cold pressing and subsequent working section treatment are required within a certain time after the application when the adhesive is used. Otherwise, the plate blank loses moisture due to glue, the glue applying surface is dry, and cracking is caused in assembly, so that the production efficiency of the plate is influenced.
