Embodiment 1

[0063] (1) Mix the isocyanate glue, paraffin wax and antimony trioxide with a mass ratio of 93:3:4 at room temperature under airtight conditions to obtain an adhesive; then mix 10 parts by weight of waste epoxy resin powder with 0.84 Adhesives in parts by weight are mixed and paved at room temperature, and then the paved materials are transported to the pre-pressing machine through the conveyor belt for pre-pressing. The pre-pressing pressure is 200kg / m 2 , the temperature is 25°C; then the pre-pressed material is transported to the hot press through a closed pipeline for hot pressing, and the pressure of the hot pressing is 55kg / m 2 ~65kg / m 2 , and the temperature is 170° C. to 190° C. to obtain a composite plate.

[0064] (2) The composite sheet material that step (1) is obtained is left standstill 10min at normal temperature on the air-drying machine, then uses the sawing machine to saw the composite sheet material after air-drying board to the size required by specificati...

Abstract

The invention provides a producing method of a novel environment-friendly plate, which comprises the following steps: a) mixing and paving waste epoxy resin powder and an adhesive, and sequentially performing prepressing and hot pressing to form a composite plate, and b) sequentially performing airing and finished treatment on the composite plate obtained in the step a) to form the novel environment-friendly plate, wherein the adhesive comprises an isocyanate adhesive, paraffin and antimonous oxide. Compared with the prior art, the novel environment-friendly plate is prepared through the specific technical steps by taking the waste epoxy resin powder (HW13 organic resin waste) as a principal raw material under the action of the specific adhesive; the waste is changed into valuables; the obtained novel environment-friendly plate has higher mechanical properties and combustion performance simultaneously and is low in release amount of soluble heavy metals and formaldehyde.

Description

technical field [0001] The invention relates to the technical field of waste utilization, and more specifically relates to a novel environmentally friendly board and a production method thereof. Background technique [0002] The chemicals listed in the "Catalogue of Hazardous Chemicals" are hazardous wastes after they are discarded. If they are not managed in a standardized manner, they may cause harmful effects on the environment or human health. Among them, HW13 organic resin waste mainly comes from the manufacture of synthetic materials, such as substandard products produced in the production process of resin, latex, plasticizer, glue / adhesive, and non-specific industries, such as waste copper clad laminates, printed circuit boards, Waste resin powder produced after circuit board crushing, sorting and metal recycling. [0003] At present, the disposal methods of waste epoxy resin powder in the existing technology mainly adopt landfill and incineration, which not only was...
