The present application relates to a kind of environment-friendly water-based phenolic resin anticorrosive coating and its preparation process, belong to the field of coating technology.The coating is made of water-based phenolic resin emulsion, hyaluronic acid-lysine composition load nano SiO2-ZnO composite filler, synergistic anticorrosive filler, wetting dispersant, film forming aid, leveling thickener, defoaming agent and deionized water.The superhydrophilic of hyaluronic acid fundamentally solves the dispersion and storage stability problem of phenolic resin in aqueous phase, and the amino group of its lysine side chain can also chemically bond with resin during curing, significantly enhancing the adhesion, flexibility and interfacial bonding strength of coating.At the same time, nano SiO2, ZnO and synergistic anticorrosive filler construct a multiple synergistic anticorrosive network of physical shielding, sacrificial anode and chemical passivation, achieving long-term active protection.The whole system uses water as medium, selects bio-based raw materials and low VOC additives, and the environmental protection is outstanding.

The application discloses a preparation method of a functional composite diaphragm and relates to the technical field of hydrogen production by water electrolysis. The preparation method comprises the following steps: preparing a casting solution: mixing a polymer with a solvent, heating and dispersing to prepare a uniform polymer solution; mixing zirconium oxide and a coupling agent with the solvent, ultrasonic dispersion to obtain an inorganic material dispersion liquid containing the coupling agent; under stirring, adding the dispersion liquid into the polymer solution, continuously stirring to obtain a uniform casting solution; forming a base film: coating the casting solution on a polyphenylene sulfide support net, placing in an oven after standing at room temperature to dry, and obtaining a composite base film; surface modification: sequentially immersing the composite base film in a first organic alkali solution and a second organic alkali solution, washing with a solvent after each immersion, and obtaining the functional composite diaphragm after washing.

The application discloses a high-salt-resistant foaming agent, which can meet the requirements of drilling construction in complex strata by coping with harsh geological conditions in the process of foam drilling and multiple requirements of foam inhibition and foaming capacity. The foaming agent is composed of the following components in percentage by mass: 12-60wt% main foaming agent, 10-30wt% auxiliary foaming agent, and the balance of water. The main foaming agent is a betaine zwitterionic surfactant containing a polyether chain segment, and the auxiliary foaming agent is an amino propionic acid type zwitterionic surfactant. The foaming agent system prepared by the application has the advantages of temperature resistance of 140 DEG C, salt resistance of 360000mg / L NaCl, excellent foaming effect, good salt resistance and good inhibition effect on hydration of mud shale.
