The invention discloses a preparation method of polyputty used for wood furniture, the polyputty is composed of a main agent and a curing agent. The main agent is composed of unsaturated polyester resin, styrene, triallyl phosphate, bentonite, white alundum, gas phase SiO2, attapulgite clay, hydroquinones, copper naphthenate, dimethylaniline, titanium dioxide and cobaltous naphthenate; the curing agent is composed of cyclohexanone peroxide, gas phase SiO2, titanium dioxide and polyvinylpyrrolidone; the preparation method comprises the following steps: the main agent production, curing agent preparation, putty preparation and the like. The polyputty has the advantages of good application property, fine putty membrane, smoothness, flattening, good flexibility and shrinkage resistance, and enable a matching usage with various mainstream wood paints such as acrylic acid, nitro, polyester, polyurethane and the like in market.

The invention provides a preparation method of Esomeprazole and a preparation method of Esomeprazole sodium, and (1S,2S)-(-)-1,2- hexamethylene diamine-D-tartrate is used as a chiral ligand, cobaltous naphthenate is used as catalyst, and Esomeprazole is prepared by asymmetric oxidation of 2-(((4-methoxy-3,5-dimethyl-2-pyridyl)methyl)sulfur-base)-1H-benzimidazole under the effect of catalyst with catalysis amount, and the prepared Esomeprazole has a better stereoselectivity and generation of peroxide sulfone is avoided. Simultaneously, sodium hypochlorite or sodium peroxide are used as oxidizing agent for preparing Esomeprazole sodium, and the sodium containing compound in the reaction process is used as oxidizing agent and sodium source, thereby the oxidation reaction and the salt forming reaction can be completed in the same reaction system with simple synthesis process.

The invention discloses a high-strength antistatic composite material sheet. The high-strength antistatic composite material sheet comprises composite material outer structure layers and a conductive core layer. The conductive core layer is located between the upper and lower outer structure layers. The outer structure layer is prepared from unsaturated polyester resin, methyl ethyl ketone peroxide, cobaltous naphthenate, modified graphene and a glass fiber cloth through compounding. The conductive core layer is prepared from unsaturated polyester resin, methyl ethyl ketone peroxide, cobaltous naphthenate, organized copper powder, carboxyl-terminated liquid nitrile rubber, dibutyl phthalate and a glass fiber mat through compounding. The preparation method is convenient. The traditional composite material molding technology can be used for production and processing without improvement. In production, a degree of mechanization is high, labor is reduced and a production cost is low. The high-strength antistatic composite material sheet has good mechanical properties, conductive performances and antistatic performances, can be used at a high temperature for a long time, has large rigidity and creep resistance, does not produce deformation, has good designability and can be used for petrochemical engineering and metallurgy occasions with high-strength antistatic composite material sheet use demands and high strength and antistatic performance requirements.
