In the invention, the resin glass fiber powder is matched with filling materials and a fireproof adhesive so that the fireproof board has excellent fireproof performance. The resin glass fiber fireproof board is small in specific gravity, is lighter in weight and satisfies recycle utilization of industrial waste materials and daily life electronic waste products, thereby achieving comprehensive utilization of the resin glass fiber powder.
Description
Technical field
The present invention relates to a kind of resin glass fiber PLASTIC LAMINATED and preparation method thereof, refer in particular to a kind of utilize the waste printed circuit board of recovery, copper-clad plate treated extraction useful metal powder after the PLASTIC LAMINATED prepared for main raw material of resin glass fiber powder and preparation method thereof.
Background technology
Flourish along with electronic industry, the process of waste electron wiring board, useless copper-clad plate scrap stock and defect ware grows with each passing day.Correspondingly waste printed circuit board, copper-clad plate sorting process extracting the process of these industrial solid wastes of resin glass fiber powder residual after metal, dispose and also become a large difficult problems.Arbitrarily topple over and can cause secondary pollution, burning, landfill can produce high expense and consume land resources.How properly to dispose and effectively fully utilize resin glass fiber powder and become the important topic solving environmental issue and face.Meanwhile, because resin glass fiber powder possesses waterproof, anticorrosion, anti-soda acid and heat insulation, flame-retardant and many other characteristic, therefore rubber, the stopping composition of plastic industry and the stopping composition etc. of antiseepage mending-leakage can be directly used in, thus there is recovery value to a certain degree.
Summary of the invention
The problem that the present invention need solve is to provide PLASTIC LAMINATED that a kind of fiberglass resin powder utilizing the waste and old circuit board of recovery to produce prepared for main raw material and preparation method thereof.
The invention provides a kind of fiberglass resin PLASTIC LAMINATED, the composition group component of this PLASTIC LAMINATED is, resin glass fiber powder, volcanic ash, magnesium oxide, magnesium chloride or magnesium chloride hexahydrate; The proportioning that described each component is counted by weight is, 50 ~ 70 parts, resin glass fiber powder, volcanic ash 15 ~ 25 parts, 10 ~ 20 parts, magnesium oxide, magnesium chloride or magnesium chloride hexahydrate 2 ~ 8 parts.
Wherein, described resin glass fiber powder is by waste and old circuit board, copper-clad plate scrap stock and the defect ware thereof reclaimed from society or industrial and mining enterprises, obtains after the physical treatment modes such as pulverizing, separation extract metal powder.
The preparation method of described PLASTIC LAMINATED is, after the composition group component of described PLASTIC LAMINATED is taken in proportion, add appropriate water after described starting material being put into stirrer mixing to stir, again through laminator roll extrusion compression moulding, natural thermal insulation maintenance 8-12 hour, cutting is tailored into specification shape and size, to obtain final product.
The recovery approach of the resin glass fiber powder in raw material is after the mixture of one or more in the useless electronic circuit board, copper-clad plate scrap stock or the defect ware that are generically and collectively referred to as useless copper-clad plate is pulverized (first coarse breaking fine crushing again), magnetic separation or washing, metal is separated with nonmetal and obtains resin glass fiber powder after extracting metal powder; Reclaiming the most preferred result of leaching process is that described resin glass fiber powder copper factor is less than 0.2%, and water content is less than 3%.Volcanic ash is commercially available eruption and natural volcanic ash, and major ingredient is active silica and activated alumina, plays the effect of high-temperature-resistant adhesive in the present invention.Magnesium oxide is commercial, in this as fire-resistant stopping composition.Magnesium chloride or magnesium chloride hexahydrate are commonly called as halogen sheet, are high-temperature-resistant adhesive.
The present invention utilizes useless electronic circuit board, the industrial residue that copperclad plate scrap stock and defect ware produce after getting copper, the resin glass fiber powder obtained after processing treatment is again as main raw material, after coordinating some other auxiliary materials, just can produce one and burn more than three hours time still intact fire-proof board through 1200 ° of C high temperature.Because resin glass fiber powder possesses waterproof, anticorrosion, anti-soda acid and heat insulation, flame-retardant and many other characteristic, so in the present invention, resin glass fiber powder through with the coordinating of stopping composition and fire resistant adhesive, after processing, gained PLASTIC LAMINATED can realize excellent fire resistance, and proportion is little, more lightweight, meets the function recycling industrial waste and daily life electronic waste, achieves the comprehensive utilization of resin glass fiber powder.
