Abstract

The invention discloses a manufacturing method of a composite enhanced insulating section bar. According to the invention, with a modification technology and a room temperature solidification technology, waste circuit board resin powder, waste polyurethane powder and biomass powder are solidified into a section bar under room temperature. Specific steps of the method are that: after a sieving process, waste circuit board resin powder with a granularity range of 0.5 to 5mm, waste polyurethane powder with a granularity range of 1 to 20 mm, and biomass powder with a granularity range of 1 to 10mm are blended-modified, and cemented; the slurry is injected into a testing mold, and is shaped; the testing mold with injected slurry is placed on a vibrating machine to be vibrated for 1 to 5min, such that air bubbles are removed, and a hydro-thermal synthesizing reaction of the gel material is accelerated; the material is then processed through a surface treatment process that the surface of the slurry is flattened; the slurry is stood for 24 hours, and is demolded; the resulting material is dried, such that the composite enhanced section bar is obtained. According to the invention, no pollution is brought to the manufacturing processes. The technology is simple; the cost is low; the produced section bars have great application value; and low-carbon, environment protection and resource re-utilization are realized.

Description

technical field [0001] The invention relates to a method for manufacturing a composite reinforced thermal insulation profile, in particular to a method for manufacturing a composite reinforced thermal insulation profile with waste circuit board resin powder, waste polyurethane powder and biomass powder. Background technique [0002] With the rapid development of the economy and the electronic information industry, the replacement of electronic and electrical products is increasing, resulting in the formation of a large amount of electronic waste. Discarded circuit boards are an important part of electronic waste. Recycling them can not only save resources but also avoid environmental pollution caused by them. Metal is the most important economic driving force in the waste circuit board recycling industry. Researchers also focus on the recovery of valuable metals in waste circuit boards, often ignoring the recycling and reuse of resin powder. At present, waste circuit board ...
