High-temperature resistance waste synthetic stone re-use method

Abstract

The invention discloses a high-temperature resistance waste synthetic stone re-use method, comprising the following steps: 1) soaking and cleaning the surface of waste synthetic stone with clean water; 2) roasting the waste synthetic stone with a baker; 3) cracking the waste synthetic stone to 5mm of particles with a crusher; 4) grinding the particles of the waste synthetic stone to 100-180 meshes of powder with a pulverizer; 5) drying the powder with a baker; 6) adding liquid epoxy resin and high temperature curing agent in the dry powder and mixing the mixture to be pasty; 7) adding 40-50 parts of glass fiber in the pasty material by weight and mixing the mixture evenly; 8) drying the mixture with a baker to ensure that the mixture contains less than 0.5% of moisture content; 9) pressing the mixture with a pressing machine to 3-18mm of plates; 10) polishing the plates with a polisher to ensure that the plates are smooth; the high-temperature resistance synthetic stone plates prepared by the method has the same properties as the agglomerated stone.

Description

technical field [0001] The invention relates to a processing method, in particular to a method for reusing high-temperature-resistant synthetic stone waste. Background technique [0002] High-temperature-resistant polymer composite materials, commonly known as synthetic stone, high-temperature-resistant reinforced glass fiber board, ASC-HG, 2576GP, CDMA, high-temperature nano-composite materials, etc., have a common feature: they are all polymer composites of fiber and resin, It can withstand high temperatures above 200 degrees Celsius and has good machining performance. It is mainly used to make PCBA board welding molds or tin furnace carriers. At present, about 3,000 tons of synthetic stone waste is produced in China every year. Due to the high temperature resistant polymer Composite materials are not easy to dissolve. At present, there is no way to reuse them in the world. Generally, they are buried after use. Therefore, developing a processing method for reusing syntheti...
