Abstract

The invention discloses a preparation method of a coal ash-resin composite material suitable for extrusion molding. The method comprises the following steps of: surface modification of coal ash; preparation of the coal ash-resin composite material; and extrusion molding of the coal ash-resin composite material, wherein the temperatures of three-sectional screws are 165 DEG C, 185 DEG C and 180 DEG C respectively; the temperature of a nozzle is 180 DEG C; the rotating speed of the screw is 10-15rpm (revolutions per minute); and a sample is obtained after being cooled by water. The coal ash-resin composite material suitable for extrusion molding is formed through the following processes: performing surface modification on the coal ash of which the granularity is 200 meshes, and compounding the coal ash subjected to surface modification with resins of polrvinyl chloride (PVC), low-density polyethylene (LDPE) and the like, and assistants such as chlorinated polyethylene (CPE), ethylene-vinyl acetate (EVA), triphenyl phosphate and calcium stearate.

Description

technical field [0001] The invention relates to building material technology, in particular to a method for preparing a fly ash-resin composite material suitable for extrusion molding. Background technique [0002] The fly ash component contains a large amount of SiO 2 and Al 2 o 3 , has high industrial reuse value. The fine ash particle size of fly ash produced by Hanzhong Zinc Industry Co., Ltd. is above 200 mesh, accounting for 90%. After surface modification, it can form a good interface with resin, which can be used for the development of fly ash-resin composite materials . Fly ash-resin composite materials can be used in door and window frames, building decoration, wall sound insulation and insulation layers, etc., which can not only bring economic benefits to enterprises, but also protect the ecological environment and generate social benefits. [0003] The existing fly ash utilization technologies are mainly concentrated in the fields of construction, agricultur...
