Manufacturing method of novel environment-friendly bio-based lignin glue formaldehyde-free plate

Abstract

The invention relates to a manufacturing method of a novel environment-friendly bio-based lignin glue formaldehyde-free plate. The method comprises the following steps of slicing; screening; flaking;shaving drying; sizing; paving; pre-pressing; hot pressing; plate airing; plate sawing; sanding; checking and grading; and packaging and warehousing. In general, the plate has the advantages of high strength, low formaldehyde emission, environmental friendliness and safety.

Description

technical field [0001] The invention belongs to the technical field of plate processing, and in particular relates to a method for preparing a novel formaldehyde-free environmentally friendly plate based on bio-based lignin glue. Background technique [0002] Particleboard is also called bagasse board. It is a wood-based panel made of wood or other lignocellulosic materials, which is glued under heat and pressure after applying adhesives. It is also called particle board. It is mainly used in furniture manufacturing and construction industry and In the manufacture of train and automobile carriages, because the particleboard structure is relatively uniform and the processing performance is good, it can be processed into large-format boards according to needs. It is a good raw material for making furniture of different specifications and styles. The finished particleboard does not need to be dried again and can be directly The performance of sound absorption and sound insulation...

Problems solved by technology

[0002] Particleboard is also called bagasse board. It is a wood-based panel made of wood or other lignocellulosic materials, which is glued under heat and pressure after applying adhesives. It is also called particle board. It is mainly used in furniture manufacturing and construction industry and In the manufacture of train and automobile carriages, because the particleboard structure is relatively uniform and the processing performance is good, it can be processed into large-format boards according to needs. It is a good raw material for making furniture of different specifications and styles. The finished particleboard does not need to be dried again and can be directly The performance of sound absorption and sound insulation is also very good. At present, my country's particleboard industry is developing rapidly, but there are generally problems of small scale, backward equipment and technology. Dust, etc. are used as raw materials for particle boards. Therefore, the quality of particle boards produced in my country is generally poor, and there is also the problem of serious excessive formaldehyde. The furniture produced by such particle boards will seriously affect the health of residents. Therefore, it is necessary to provide a high-strength , low formaldehyde emission, environmentally safe bio-based lignin glue formaldehyde-free new environmental protection board preparation method
