Zero-formaldehyde flakeboard suitable for routing machining and preparation method of zero-formaldehyde flakeboard

The invention discloses a zero-formaldehyde flakeboard suitable for routing machining and a preparation method of the zero-formaldehyde flakeboard. The zero-formaldehyde flakeboard is prepared from, by weight, 100 parts of wood shavings, 8-25 parts of unsaturated polyester resin, 0.1-1.5 parts of an initiator, 0.01-0.5 part of an accelerant, 0.01-3 parts of a surface treating agent and 0.5-2 parts of a water-proofing agent. The surfaces of the wood shavings are treated, the unsaturated polyester resin is utilized as an adhesive, and therefore the produced flakeboard contains no formaldehyde, the problem of formaldehyde pollution in life space can be effectively solved, and a new solution way is provided for artificial board products for getting rid of formaldehyde release problems. The board is good in water resistance and high in mechanical property, the good routing machining performance is achieved, industrialization can be achieved without modifying an existing flakeboard production line, and the additional value of the flakeboard can be increased.
