High-performance pnenolic aldehyde amine hardener for epoxy resin and preparation thereof

The invention discloses a high-performance phenol-aldehyde amine curing agent used for epoxy resin and a preparation method thereof and relates to a phenol-aldehyde amine epoxy resin curing agent which is a low-viscosity epoxy resin curing agent applicable to low-temperature damp construction. The curing agent comprises the main components with the weight percentage as follows: 36-45 percent of phenol, 5-8 percent of long-chain phenol, 18-22 percent of formaldehyde solution, 20-25 percent of ethylene polyamine, 3.5-5.5 percent of 4, 4'-diminodiphenyl-methane and 1.5-2.5 percent of polyphenyl polyamine methane. The invention uses a form of normal pressure reaction, thereby avoiding the risk of high temperature and high pressure synthesis; the production method is simple; the curing agent has high activity, low viscosity, good construction and high intensity, so the curing agent can overcome the disadvantages that the epoxy resin is cured slowly under low temperature and has low intensity later. A cured product obtained by curing the epoxy resin with the curing agent overcomes the disadvantage of the brittleness of ordinary phenol-aldehyde amine. The phenol-aldehyde amine epoxy resin curing agent is applicable to the fields of building reinforcing, bridge reinforcing, sealing bonding, water conservancy project, antiseptic paint, etc.

Synchronous desulfurization and denitrification technology of coal-fired flue gas by taking hydrogen sulfide as reducing agent

The invention discloses synchronous desulfurization and denitrification technology of coal-fired flue gas by taking hydrogen sulfide as a reducing agent. The technology comprises the following steps: 1) preparation of dissolved H2S; 2) preparation of a mixed gas of H2S, NO, NO2, and SO2; and 3) synchronous desulfurization and denitrification. According to the technology, integration of a desulfurization and denitrification device is authentically realized. NO and NO2 in the coal-fired flue gas are converted into N2 and water; SO2 and H2S are converted to high-purity elemental sulfur; and organic matters in waste water are further removed, so that treatment of wastes with other wastes is realized. Elemental sulfur is recycled through the technology; one part of elemental sulfur is cycled and utilized to maintain equipment operation; and the other part of elemental sulfur is output as a product. The reducing agent of H2S in the technology is prepared from an in-situ product of elemental sulfur through reduction, can be prepared when used, and does not need to be bought outside. Therefore, cost of purchase, transportation, and storage and potential security risk are avoided. Compared with a mainstream device, the desulfurization and denitrification device is significantly lower with respect to land occupation, construction cost, operation cost, and the like.
