The invention discloses a method for synthesizing a coating printing thickening agent. The method comprises the steps of: preparation of polyurethane prepolymer, preparation of polyurethane-polyacrylic acid composite emulsion, dropwise addition of ammonia water into the composite emulsion for pH regulation, and the like. The high thickening capability of polyacrylic acid and the good diffusion resistant effect of polyurethane are utilized, an interpenetrating polymer network synthesis technology is adopted, and a novel coating printing thickening agent with high thickening capability and a good diffusion resistant effect is prepared by stepwise synthesis and accurate control over a reaction condition.

The invention discloses a water soluble polyurethane associative thickener and use thereof. In the invention, the water soluble polyurethane associative thickener with a branch structure is obtained by dehydrating polyethylene glycol and a surface-active substance which serves as a capping agent and has a plurality of ethyoxyl structures, and adding diisocyanate and a diisocyanate polycondensate serving as a chain extender in a protective atmosphere of an inert gas to perform a reaction in an organic solvent, and the water soluble polyurethane associative thickener has high thickening capability and can be widely used. In the invention, the surface-active substance with plurality of ethyoxyl structures is used as the capping agent to participate in an reaction, so the molecular weight is high, the reaction is smooth and the industrial production is convenient; the diisocyanate and the chain extender are added at one time, so the uncertainty of the product, which is caused by the waterbrought in during stepwise addition, is avoided; and the efficiency of the reaction of the carbimide group and the hydroxyl in an organic solvent is high, a catalyst is not used, the hydrolysis effect of the catalyst on the product is avoided, and the stability of the product is high.

The invention provides composite environment-friendly waterproof dry-mixed mortar and a preparation method thereof. The composite environment-friendly waterproof dry-mixed mortar is prepared from cement, sand, modified polymer latex powder, admixtures and chemical additives, wherein the sand is composed of fine sand and kaolin tailing sand, the modified polymer latex powder is siloxane-styrene-acrylate copolymer latex powder, the admixtures comprise high-calcium fly ash, steel slag micropowder and modified chrysotile fibers, and the chemical additives comprise modified waterproof adhesive powder, dialkyl polysiloxane, methacrylic acid, hydroxyethyl methyl cellulose and 2-acrylamide sodium 2-methallyl sulfonate. In this way, the composite environment-friendly waterproof dry-mixed mortar is high in compressive strength, good in waterproof performance, high in cracking resistance and shrinkage resistance and low in cost.

The invention belongs to the field of polymer materials, and discloses a preparation method of a cationic inverse emulsion thickener. The cationic inverse emulsion thickener is prepared by an inverse emulsion polymerization method from a monomer mixture accounting for 15 to 30 wt% of the total weight of the emulsion. ; The monomer mixture includes cationic monomers, nonionic monomers and cross-linking agents. The cationic thickener prepared by this method has excellent thickening ability under the condition of low active substance dosage. Compared with commercial products, it has higher viscosity at low active content (<1wt%), or can use less thickener to achieve a specific viscosity.

The invention provides a lubricating oil viscosity index improver and a preparation method thereof; the lubricating oil viscosity index improver has stable chemical performance, oxidation resistance, shear resistance and good compatibility with lubricating oil; in addition to good thickening ability to the lubricating oil, the lubricating oil viscosity index improver further has excellent anti-shear stability and viscosity-temperature performance. The viscosity index of the lubricating oil after modification is greater than 150, and low-temperature kinematic viscosity is less than 1600mpa.s. The lubricating oil viscosity index improver can not only be used for preparing multi-level lubricating oil, but also be used for improving the viscosity index of base oil of the lubricating oil with the low viscosity index, thereby having broad application prospects.
