Abstract

The invention discloses a preparation process of a bagasse base artificial board. The preparation process of the bagasse base artificial board comprises the following steps: (1) pretreatment of bagasse: the bagasse is put in an oven for drying under the condition of 40-55 DEG C, and then, is put in a crusher for crushing by 30-45 min at a speed of 200-500 r/min to obtain bagasse powder, wherein the fineness reaches 100 meshes; (2) a basal body material is prepared; (3) spraying: a layer of flame retardant pulp is uniformly sprayed on the surface of the basal body material, and is aired; and the thickness of the pulp is controlled to obtain a material to be pressed; and (4) pressing: the material to be pressed is poured in a mold for layer-by-layer pavement, and is fed in a mold pressing former for prepressing, continuous heating to 50 DEG C, hot pressing, pressure relief and cooling to the room temperature; and then, a layer of flame retardant pulp is coated to put in a dryer for drying and molding; and the bagasse base artificial board is obtained after cooling. The prepared artificial board achieves the effects of high-temperature resistance and flame retardance, and achieves higher market popularization value.

Description

【Technical field】 [0001] The invention relates to the field of artificial board preparation, in particular to a preparation process of bagasse-based artificial board. 【Background technique】 [0002] my country is a country with poor forest resources. According to the results of the eighth national forest resources inventory in 2014, the per capita forest reserves are less than 1 / 4 of the world level, about 9.42m 3 , ranking 122nd in the world. In addition, the contradiction between the effective supply of forests and the growing social demand is still prominent. my country's dependence on foreign timber is close to 50%, and the situation of timber safety is severe. The recoverable area of ​​the existing timber forests only accounts for 13%, and the recoverable stock accounts for only 23%. The available resources are few, and the structural contradiction between timber supply and demand is very prominent. At the same time, the fragility of the forest ecosystem has not been ...
