FIELD: process engineering.
SUBSTANCE: invention relates to woodworking and may be used in production of fireproof particle boards. Proposed composition comprises wood particles, amidophosphate as fire-retardant additive, binder including resin and formaldehyde solution as additive. Resin binder contains melamine-phenolic resin and, additionally, latent catalyst while outer layers binder contains melamine-phenolic resin, latent catalyst and surfactant.
EFFECT: high-efficiency composition, higher quality of particle boards, better manufacturability.
