Formaldehyde-free zero-carbon environmentally-friendly board synthetized by circuit board and manufacture technology thereof

Abstract

The invention discloses a formaldehyde-free zero-carbon environmentally-friendly board synthetized by circuit board and a manufacture technology thereof. The compaction raw material of the environmentally-friendly board comprises circuit board powder, isocyanate, release agent and water, and wood fiber powder and carbon filament fiber also can be added. The manufacture technology of the board comprises the following steps of: evenly stirring isocyanate and release agent; adding water to stir; drying the circuit board powder at constant temperature; adding processing accessory ingredient to beevenly mixed; feeding, paving a platen; smoothly releasing pressure to obtain the board after pressurizing; and standing and supplementing pressure. The board manufactured by the manufacture technology by the above raw material ingredients is the formaldehyde-free environmentally-friendly board which is completely free from formaldehyde, and the use amount of recovery powder of the circuit board can be above 95%, therefore improving waste use ratio. In the board manufacture process, the isocyanate and water can react to absorb water, so that the material moisture rate is lowered, no bubbles are formed, and the problem of exploring boards can be solved. The board manufactured by taking the circuit board recovery powder as the main raw material has good water-proof performance.

Description

technical field [0001] The invention relates to an environment-friendly plate, in particular to an formaldehyde-free and zero-carbon environment-friendly plate synthesized by circuit board powder. The invention also relates to a manufacturing process of the formaldehyde-free and zero-carbon environment-friendly plate synthesized by circuit board powder. Background technique [0002] The raw material of traditional wooden boards is wood, which needs to cut down forest resources, resulting in soil erosion, various natural disasters, affecting the balanced development of the natural environment and ecology, not environmentally friendly and unable to effectively save energy and reduce emissions. This kind of wood product board releases a large amount of formaldehyde, and it is easy to swell, deform, bend, and mold when exposed to water. It is not resistant to corrosion, acid, and alkali, and is flammable. [0003] With the rapid development of cities around the world, a large a...

AI Technical Summary

Problems solved by technology

When the board raw material is mainly circuit board powder, the slab is subjected to the dual effects of pressure and heat during the hot pressing process, and the water vapor cannot be absorbed, which easily leads to the occurrence of bubbling. The external expansion force is greater than the internal stress, resulting in the phenomenon of plate bursting
