Abstract

The invention discloses light polyurethane plastic paving material. The invention comprises a component A, a component B, composite catalyst and black micellar particles, wherein pulverized fuel ash is used in the component B as the packing material, the invention finds appropriate raw material ratio, and solves the flowablity of the pulverized fuel ash component, thus ensuring the traditional industrial refuse pulverized fuel ash to be converted into treasure from waste, so as to produce the light polyurethane plastic paving material with low cost and meeting the market demand, and thereforethe invention not only is in favor of reducing the pollution of the pulverized fuel ash to the environment, but also can create good economic and social benefits. The light polyurethane plastic pavingmaterial obtained by utilizing the pulverized fuel ash production has the advantages that the weight is light, the specific surface is large after pavement, the pavement use amount of unit volume isreduced, the cost is greatly decreased, and each performance can achieve the national standards, therefore the invention provides a new broad prospect for the comprehensive utilization of the pulverized fuel ash, and makes contribution for the state to develop physical culture.

Description

technical field [0001] The invention relates to a lightweight polyurethane plastic paving material, in particular to a novel lightweight polyurethane paving material using fly ash as a filler. Background technique [0002] Fly ash is a kind of pozzolan-like mixed material formed after pulverized coal is burned at high temperature. It is a powdery substance collected by a dust collector after a certain fineness of pulverized coal is burned in a boiler (1100-1500°C). , is a highly dispersed aggregate of fine particles, gray or off-white in dry state, non-cohesive, fly ash with high water content is gray-black, due to surface tension, most of the fly ash particles are hollow particles Beads; the surface of the microbeads is uneven, extremely uneven, and the micropores are small; some of them are connected due to collisions in the molten state, forming rough surfaces and honeycomb particles with many corners, and their particle sizes are concentrated in 10-1000μm, about Account...
