Abstract

The invention relates to an environment-friendly tree pool cover plate, a side plate and a preparation method and application thereof. The tree pool cover plate of the present invention contains 40-70wt% of fly ash, 25-50wt% of polyvinyl chloride recycled material, 0-20wt% of light calcium, 1-3wt% of stabilizer, 0.9-2.5wt% of modifier, It is prepared from raw materials of 0-1 wt% foaming agent, 0-5 wt% foam regulator, 0.1-1 wt% first lubricant and 0.1-1 wt% second lubricant. The environmental-friendly tree pool cover plate and side plate of the present invention have low raw material cost, simple preparation process, high added value, recyclable and reused products, and good economic benefits can be obtained.

Description

technical field [0001] The invention relates to the field of special paving, in particular to tree pool cover plates and side plates. Background technique [0002] Fly ash is a kind of solid waste produced in the production process of coal-fired power plants, and its output accounts for about 5-20% of the total amount of coal burned. The annual discharge of fly ash in my country is about 500 million tons. At present, the amount of fly ash stacked in my country is more than 2 billion tons, and the land occupied by the ash storage yard is about 4×104km 2 , which not only seriously pollutes the environment, but also takes up a lot of land resources. At present, there are technical applications of doping fly ash to prepare lightweight materials, refractory materials, heat insulation materials, building materials, and daily ceramic materials, but the effect of high value-added utilization of fly ash is not obvious. [0003] Polyvinyl chloride (PVC) resin is a thermoplastic high...
