Heat-insulating flame-retarding pulverized fuel ash decorative plate and production method thereof

Abstract

The invention discloses a production method of a heat-insulating flame-retarding pulverized fuel ash decorative plate. The production method includes the steps of A1. surface modification of pulverized fuel ash; A2. preparation of epoxy resin glue solution; and A3. forming of the decorative plate. Due to the development and utilization of the colorful decorative plate, can effectively utilize waste residues can be effectively utilized, so that waste can be changed into wealth, and the development cost is low; the pulverized fuel ash used for development of the colorful decorative plate has high additional value compared with the pulverized fuel gash applied to roadway pavement, building block production, and cement production; the colorful decorative plate has the characteristics of good heat insulating, waterproof and flame-retarding performances, porousness, light weight, high strength, good toughness, attractive appearance, and easiness in coloring and the like, and can be used for the fields such as interior wall decoration, soundproof and heat-insulating layers of walls. Besides, compared with the conventional similar products, the colorful decorative plate has the advantages of wide raw material source and low production cost. The production technology of the colorful decorative plate has low requirement on production condition, the technological operation is simple, the production investment is low and the effect is remarkable, therefore, the production technology is suitable for production of medium-sized and small enterprises, which is also a precondition that the technology is popularized and applied.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a fly ash heat-insulating and flame-retardant decorative board and a preparation method thereof. Background technique [0002] The main components of fly ash are CaO, SiO 2 、Al 2 o 3 Such oxides have certain activity and can be used in the development of fly ash-resin composite boards. 90% of the fly ash fine ash produced in the production of Hanzhong Zinc Industry Co., Ltd. is above 200 mesh. After surface modification, it can form a good interface with the resin, which can make the fly ash-resin composite board have a high performance. Fly ash-resin composite panels can be used in the fields of laying floors, interior wall decoration, wall sound insulation and insulation layers, etc., which can not only bring production benefits, but also avoid accumulation pollution caused by incomplete utilization of fly ash. [0003] The existing fly ash utilization technologies are m...
