Typical core materials for board core plywood for fn: A < to: l) or Sandino-1 JX3'' No. 1 so-called eaves plywood include ζ honey 11 core, collate core, and hiroruko ryo-tongue, so-called paper core. Typically used.

The purpose of this was to reduce the weight of thick plywood or thick metal piles, etc., but recently, not only weight reduction but also T4i4*: strength, rigidity, heat insulation, durability, weather resistance, water resistance and moisture resistance. Due to its heat resistance, metal plate core plywood is in particular demand for building materials such as floorboards and walls of houses, etc., and as structural materials.

Therefore, with the aim of imparting the above-mentioned various performances to various paper cores, so-called amino-based initial thermosetting resins such as urea resins, melamine resins, phenol resins, and co-condensed resins of these are used. In some cases, techniques for impregnating and applying thermoplastic resins are known.

However, the above-mentioned conventional resins have insufficient permeability into paper and coating film-forming properties, and the curing reaction is slow, so under certain curing reaction conditions, sufficient rigidity, water resistance, moisture resistance, and heat resistance are required. Various types such as (〈1-ability cannot be expressed until 1υj.

In order to achieve this goal, the present inventors conducted repeated tests and discovered that a resin fluoride containing aqueous emulsion 7 and formalin group I-containing fat control was effective. Completed the invention.

On the other hand, in the present invention, the formalinol resin 11 compound system/reservoir includes, for example, urea resin, melamine/]bj resin, urea/melamine cocondensation resin, resol/resin, phenol resin, and/or 7 resin. Examples include so-called quartz crystal melds, initial combinations with formalin, and their emuls/-]71F combinations.

Water-soluble or alcohol-soluble phenolic fats are particularly preferred because they are resistant to cancer, have rapid curing properties, and are low in formalin.

Specific examples of preferable water-soluble phenolic resins are basically those of alkali resol type;

It is surrounded by l.

'/T)llj The reason is that the mole of phenol relative to formalin is 11'1 or 15 (lower than that, only those with a low degree of initial condensation can be obtained). On the other hand, if it is 50 or more, the odor of formalin in the atmosphere will be high.
It becomes a high viscosity product at the same time as stone, f. Y tends to decrease the permeability and strength of paper (Li, kaC).

In the present invention, the blending ratio of the aqueous emulsion and the formalin condensation resin is in the range of 5 to 100 parts by weight based on the solid content of the resin in the aqueous emulsion. Preferably, by blending 5 to 50 heavy needles, the various performance characteristics of the manual can be clearly improved.

Therefore, the composition has 5 layers: f and some K.
