The invention discloses a
straw particle board manufacture method, which relates to a
particle board manufacture method. The invention solves the problem that the
straw surface includes a plurality of waxy
layers and SiO2 substance, common
urea formaldehyde resin glue and phenolic resin are hard to wet the
straw surface to cause a plurality of gluing difficulty. The invention has the method that: the straw is
cut into pieces and performed ash removal at first, and straw crushed aggregates which are performed with the pretreatment through the blending ratio of the 1:4 to 5.0 according to the
mass ratio of the straw and alkali liquor is soaked in the alkali liquor of 1.4 to 1.6 wt percent (
mass) for 10 to 15 hours, and the straw
particle board can be manufactured after
drying, glue applying, paving, pre-pressing,
hot pressing, and cooling. The equipment performance request of the straw particle board manufacture through the invention is low, the method is simple, and the operation parameter is easy to control. The method of the invention for performing
chemical treatment to the straw
raw material surface improves the
wetting property of the
raw material, greatly enhances the inner combination intensity, enlarges the application scope of the straw, releases the lack of the timber resources, and the invention has great economic and
social efficiency in the situation that the conflict between supply and demand becomes more prominent.
