Environmentally friendly wood fragrance board synthesized by using waste circuit board and plant fiber and its manufacturing process

Abstract

The invention relates to an environment-friendly wood fragrance board synthesized by utilizing waste circuit boards and plant fibers and a manufacturing process thereof. Among them, the environmentally friendly woody board adopts a three-layer structure. The first layer is the first plant fiber layer composed of plant fiber powder mixed with processing aid A, and the second layer is composed of waste circuit board powder mixed with processing aid B. The circuit board layer, the third layer is the second plant fiber layer formed by mixing plant fiber powder and processing aid A. The first plant fiber layer, the circuit board layer and the second plant fiber layer are laminated sequentially. The manufacturing process of environmentally friendly woody board includes: grinding and drying plant fibers and waste circuit boards; layered feeding and paving, pre-pressing and thickness determination, initial trimming, hot pressing, trimming, and thickness determination. The environment-friendly wood incense board of the invention can be nailed and sawed, has excellent mechanical properties and high waterproof performance. Using waste circuit boards and plant fibers as raw materials for environmentally friendly wood fragrance boards can fully recycle waste circuit boards and agricultural waste, and can also reduce the production cost of environmentally friendly wood fragrance boards.

Description

technical field [0001] The invention relates to a board, in particular to an environmentally friendly woody board synthesized by using waste circuit board powder and plant fiber powder. The invention also relates to a manufacturing process of using waste circuit board powder and plant fiber powder to synthesize the environmentally friendly wood fragrance board. Background technique [0002] With the rapid development of cities, the demand for panels is increasing. The panels used in industry and construction are mainly wooden decks, wooden multi-layer boards, and particle boards. At present, these boards have not applied the recycling technology of renewable resources, so a large number of trees need to be felled. With the growth of the demand for plates, the price of plates continues to rise. Renewable resources such as straw and bamboo and wood sawdust formed in agricultural production in various places are mainly used in the form of incineration, and the utilization rat...

Problems solved by technology

Use the pyrolysis recycling method to process waste circuit boards. The brominated flame retardants contained in waste circuit boards will produce a lot of harmful gases during the pyrolysis process (such as polybrominated diphenyl ethers can generate polybrominated dibenzodioxins) Alkanes and polybrominated dibenzofurans), this method has problems such as high cost, complicated process, and secondary environmental pollution.

The waste epoxy resin recovered by physical recycling method usually cannot be used alone, but can only be used as an additive mixed with new similar materials or other materials

None of the above methods make full use of the glass fiber material in waste circuit boards, and the recycling cost is high
