Embodiment 1

[0013] Wood fiber boards with a thickness of 3 mm are manufactured from wood fibers produced from forest residues and wood waste. Treat the wood fiber with 3% silane solution, then make the raw material treated at a drying temperature of 60°C for 1 hour, then add 5% larch extract and 5% lignosulfonate to the wood-based raw material for mixing, and The 5% degradable resin polylactic acid of the mixed material and the total material weight is paved in layers and pre-pressed into a slab, and then hot-pressed. The hot-pressing temperature is 160°C and the hot-pressing pressure is 3.5MPa. The time is 6 minutes, and finally the finished product will be put into storage after being aged and trimmed.

Embodiment 2

[0015] Wood fiber boards with a thickness of 6 mm are manufactured from wood fibers produced from forest residues and wood waste. Treat the wood fibers with 3% isocyanate solution, and then treat the raw materials at a drying temperature of 40°C for 20 minutes, then add 5% larch extract and 10% lignosulfonate to the wood-based raw materials for mixing. The 5% degradable resin polylactic acid of the mixed material and the total material weight is paved in layers and pre-pressed into a slab, and then hot-pressed. The hot-pressing temperature is 170°C, the hot-pressing pressure is 4MPa, and the hot-pressing time The time is 10 minutes, and finally the finished product is put into storage after being aged and trimmed.

Abstract

The invention relates to a manufacture method of an environment-friendly lignin composite material. A thermal pressing forming treatment technology is adopted to prepare the environment-friendly lignin composite material by using forest remains and rejected wood materials as main raw materials; after the and pretreating, adding stuffing, such as a larch extract, lignin in papermaking waste liquid, and the like; adding biological degradable resin-polylactic acid; and assembling and combining blanks. The invention is free from reliance on a formaldehyde-contained cementing compound, not only improves the plate-forming performance, but also is biologically degradable after being used by adding the degradable resin, thereby not causing environmental pollution and partially substituting the prior petroleum source products. The preparation method of the invention is simple and suitable for industrialized production. The products are provided with multifunction lignin forming products with high strength ratio, environment-friendly types, natural degradation, and the like, can be applied to the fields, such as building industry, interior decoration engineering, electric appliances, manufacturing industry, and the like and can substitute qualitative material products with similar performance.

Description

technical field [0001] The invention relates to a manufacturing method of an environment-friendly wood-based composite material, which belongs to the manufacturing method of wood-based panels. Background technique [0002] Wood is a recognized renewable, green and environmentally friendly biomass material with good environmental coordination. However, my country's wood resources are seriously insufficient, and the contradiction between supply and demand of wood and wood materials is very serious. One of the main ways to alleviate this contradiction is to vigorously develop Utilize forest residues and woody waste resources. However, at present, the utilization rate of forest residues and woody waste resources in my country is not only low, but also cause waste accumulation, serious waste of resources and environmental pollution, which is in stark contrast to the broad market demand. Therefore, making full use of forest residues and woody waste resources to manufacture new mat...
