Biodegradable drain board and preparation process thereof

The invention discloses a biodegradable drainage plate and a preparation process thereof. The drainage plate is prepared from polybutylene succinate, polypropylene resin, polyethylene resin, bamboo fibers, glass fibers, pine fibers, coconut fibers, abaca fibers, maleic anhydride, benzoyl peroxide and a lubricant. According to the invention, the main raw materials are plant fibers and have degradability; wherein the bamboo fiber, the pine fiber, the coconut fiber and the abaca fiber are easy to obtain and extremely low in cost; the bamboo fiber has an antibacterial effect, the service life of the drainage plate is prolonged, and foundation construction is facilitated; by adding the glass fiber filaments, the folding strength of the drain board can be enhanced; according to the biodegradable drain board and the preparation process thereof, the formula of the drain board is improved, the preparation process is optimized, and the prepared drain board not only has better corrosion resistance and water resistance a
