Embodiment 1
[0017] Embodiment 1 of the present invention provides a kind of use method of concealing agent, comprises the following steps:
[0018] a. Add urea-formaldehyde glue in the reactor, then add concealing agent in the reactor, the mass ratio of concealing agent and urea-formaldehyde glue is 1:20;
[0019] b. grind the mixture obtained in step a, stir and mix evenly;
[0020] c. Apply the mixture obtained in step b to the core board by using a glue applicator.
[0021] In this embodiment, the main component of the concealing agent is titanium dioxide. This type of masking agent is a conventional masking agent in the prior art, and will not be repeated here.
[0022] The method for using the concealing agent provided in this embodiment has simple steps and is easy to operate. During use, the concealer and urea-formaldehyde glue are mixed. When the concealer and urea-formaldehyde glue are mixed in a specific ratio, the composite property after coating is good, the bonding strengt...
