Method for manufacturing environment-friendly medium density fiberboard using plant straws instead of partial wood fibers

The invention discloses a method for manufacturing an environment-friendly medium density fiberboard using plant straws instead of partial wood fibers. The fiberboard is composed of the following components in parts by weight: 60-70 parts of wood materials, 20-25 parts of plant straws, 15-20 parts of urea resin, 4-6 parts of methylenediphenyl diisocyanate adhesive, 0.8-1.2 parts of paraffin, 0.2-0.3 part of caustic soda flakes, 0.2-0.3 part of formic acid, 0.25-0.3 part of ammonia chloride, and 0.15-0.2 part of melamine. The method for manufacturing an environment-friendly medium density fiberboard using plant straws instead of partial wood fibers has the following advantages: the usage amount of wood is reduced; moreover, as the methylenediphenyl diisocyanate (MDI) is a non-formaldehyde adhesive, the addition thereof results in great reduction of formaldehyde emission of the density fiberboard, improvement in the environmental protection property of the density fiberboard, and promotion of the production lev
