A preparation method for anti-ageing environment protection pressed-fibre board, comprises the following steps:

(1) barrenwort, frutus cnidii, the red sage root, Ligusticum wallichii, radix polygonati officinalis, pseudo-ginseng, matrimony vine and the root of kudzu vine are cleaned up rear mixing, add soak by water 1-2h by solid-liquid weight ratio 1:4-1:6, cooled and filtered, obtain filtrate and filter residue, filtrate is concentrated into the 1/4-1/8 of original volume, obtains concentrate;

(2) poplar is cleaned and cut pulverize after mix with the filter residue in (1), with defibrator defibrator process defibre after boiling is softening, then the concentrate added in benzene emulsion, nano zircite and (1) mixes, then to be dried to moisture content be 6-8%, obtains composite fibre material;

(3) to the composite fibre material spraying composite adhesive in (2), then carry out mating formation, precompressed, hot pressing and post-processed operation, obtain anti-ageing environment protection pressed-fibre board, hot pressing temperature is 150-170 DEG C.

Advantage of the present invention is:

The present invention improves the toughness of fiberboard, intensity and anti-wear performance by adding nano zircite, add water-fast, decay resistance that benzene emulsion improves fiberboard, in composite adhesive, add the absorption property that oyster shell whiting improves material simultaneously, harmful components in effective absorbed air, in conjunction with the interpolation of traditional Chinese medicine ingredients, make the existing good mechanical property of fiberboard that obtains and weatherability, the health-care efficacy enhance metabolism in addition, improve the health, delayed senility, simultaneously not containing formaldehyde, environmental protection, the effect purified air in addition.
