Problems solved by technology

At this time, if there is a power failure or water failure or the operator does not handle it in time, there is a risk of explosion in the reactor. Even if the operator opens the emptying valve in time, the violent boiling in the reactor will discharge a large amount of phenol and aldehyde into the surrounding air. Medium, endangering human health, corroding equipment, polluting the environment
In addition, after the phenolic polycondensation reaction is completed, vacuum dehydration is necessary, and the discharged industrial wastewater contains a large amount of free phenol and free aldehyde, which pollutes rivers and lakes and destroys the ecological environment.
Moreover, the traditional synthesis method consumes energy and labor, has a long production cycle and low efficiency

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environmentally friendly refractory material for building and a preparation method thereof. Background technique [0002] Refractory insulation material is a kind of material with high temperature resistance, small thermal conductivity, thermal shock resistance, flame retardancy, and can slow down the heat loss caused by heat conduction, heat convection, etc. It limits the low thermal conductivity through the special structure of the material Air convection to slow down heat loss. Refractory insulation materials are generally used in industrial furnaces, metallurgy, pipelines and thermal equipment to slow down the loss of heat. Most of the refractory insulation materials for industrial kiln walls are made of lightweight refractory insulation materials, such as lightweight clay bricks, lightweight high-alumina bricks, and lightweight refractory castables. Has a cer...
