Abstract

The invention provides a method for preparing a composite material, which is characterized in that the composite material uses specific fibers as a reinforcing material, and uses a specific binder, an acid-resistant powder, a modifier and a curing agent as a cementing material. It is formed through the processes of compounding glue, applying primer, laying reinforcing layer, applying surface glue, curing and curing, and acidizing treatment. The present invention has the advantages of convenient production and construction, low cost, good repairability, and resistance to concentrated acid and acid at room temperature or high temperature. The advantages of flue gas corrosion, the temperature of its resistance to concentrated acid can reach 350°C, and the temperature of acid-resistant flue gas can reach 600°C to 800°C.

Description

Technical field: [0001] The invention relates to a preparation method of a composite material, in particular to a preparation method of a composite material resistant to corrosion by concentrated acid and acid flue gas at normal temperature or high temperature. Background technique: [0002] At present, general synthetic resin-based composite materials such as epoxy FRP, unsaturated polyester FRP, phenolic FRP, furan FRP, and inorganic FRP such as magnesite FRP are not resistant to concentrated acids, especially high-temperature concentrated acids (such as 98°C at 100°C). % sulfuric acid, 97% nitric acid at 100°C) corrosion; and the anti-corrosion method under the concentrated acid medium mainly adopts thick and difficult construction and high cost methods such as ceramic tile lining, lead plate lining, and acid-resistant mortar lining, or adopts Low-carbon stainless steel, duplex stainless steel, titanium alloy, nickel alloy and other expensive alloy materials are used to m...
