Embodiment 1

[0027] The method for preparing plant fiber-based particle board by utilizing camellia oleifera husk of the present embodiment comprises:

[0028] (1) According to the liquid-solid ratio of 1:10, mix the NaOH solution with a concentration of 2% and the camellia oleifera husk fragments with a diameter of 3mm to 5mm. The pretreatment time is 1h, and the camellia oleifera husk is washed repeatedly until it becomes neutral. After filtering out the moisture in a ventilated place, dry it in an oven at 103°C for subsequent use; (2) after selecting and removing impurities, use the phenolic glue quality as 16% of the quality of the camellia oleifera husk obtained after pretreatment to sizing, and mix evenly (3) Lay the camellia oleifera husk obtained by sizing in the mold, under hot pressing pressure 4MPa, preset density is 0.8 g / m 3 , under the condition of hot pressing temperature of 170° C., hot pressing for 12 minutes to obtain plant fiber-based particle board.

Abstract

The invention discloses a plant fiber-based particle board and a preparation method of the plant fiber-based particle board. Before gluing, camellia oleifera shells are pretreated, the pretreated camellia oleifera shells are mixed with glues evenly and then horizontally laid in a mould to be formed in a hot pressing mode, and the plant fiber-based particle board is obtained. The plant fiber-based particle board is good in mechanical performance, the static bending strength is 1.49 MPa-3.5 MPa, the elastic modulus is 383 MPa-530 MPa, and the internal bonding strength is 0.31 MPa-1.02 MPa. Compared with other biomass materials, the used camellia oleifera shells have the characteristics of being low price, reproducible, rich and intensive in yield and the like. The used overall working procedure is short, the method is simple, and the method has special significance for improving the high quality utilization way of camellia oleifera shell resources and relieving the current situation that forest resources are deficient.

Description

technical field [0001] The invention belongs to the field of utilization of agricultural and forestry wastes, in particular to the field of utilization of camellia oleifera husks, and in particular relates to a method for preparing plant fiber-based particle boards by using oleifera oleifera husks. Background technique [0002] Plant fiber-based particle board refers to a new type of composite material with special microstructure and properties prepared by compounding woody or plant raw materials with other materials. In the middle of the 20th century, the rapid growth of the global economy and the population explosion caused unprecedented burdens on the earth. The development of "low-carbon economy" has become the development theme of the international community. Facing the growing development needs of human society, single wood products or wooden materials As a result, the shortage of supply in the market has intensified, and the reserves of forest resources have plummeted...
