Description
Technical Field
The invention belongs to the technical field of polyether polyol, and particularly relates to polyester ether polyol for high-performance polyurethane waterproof paint and a preparation method thereof.
Background
The polyurethane waterproof coating is a high-grade durable synthetic resin coating, has the advantages of excellent overall waterproof effect, light waterproof layer, high strength, good elasticity, strong binding power, high and low temperature resistance, corrosion resistance, easy repair and the like, and can be used for waterproof of projects such as building roofs, outer walls, basements, roads, bridges and the like.
The polyurethane waterproof paint comprises two main types of double-component polyurethane waterproof paint and single-component polyurethane waterproof paint. Compared with the double-component polyurethane waterproof coating, the single-component polyurethane waterproof coating does not need to be prepared on site when in use, is simpler and more convenient to construct, has excellent coating performance, has good waterproof and mechanical properties due to moderate viscosity of the prepolymer, does not need to be diluted by a solvent and has a urea bond structure generated after the prepolymer is solidified. However, because the single-component polyurethane waterproof coating adopts moisture curing in the film-forming curing process, the formed polyurethane material has less component content for forming a hard segment, and the mechanical property of the material is generally poorer than that of the double-component coating. In order to achieve better mechanical property indexes, various properties of the polyurethane waterproof coating can be improved by using high-quality main polyol. In a general polyurethane waterproof coating formula system, a plurality of polyether polyols are required to be compounded and used, and the polyether polyols with the molecular weight of 2000 in two functions and 5000 in three functions are usually used as main polyether polyols.
The polyol used in the polyurethane waterproof paint mainly comprises polyether type and polyester type. The polyester polyol contains ester groups, so that the synthesized polyurethane material has higher tensile strength, lower elongation, insufficient hydrolysis resistance and high price. The polyurethane material synthesized by polyether polyol has lower cohesive energy of ether bond, and the product is generally softer, higher in elongation, good in hydrolysis resistance and inferior in mechanical property as polyester.
Patent CN202110388487.5 discloses a preparation method of polyether polyol for high-performance waterproof paint, which uses a mixture of difunctional compound and trifunctional compound as initiator, uses alkali metal or DMC as catalyst, and makes polymerization reaction with alkylene oxide to obtain polyether polyol crude polymer; and refining the crude polymer to obtain the target polyether polyol. When the polyether polyol is applied to the polyurethane waterproof paint formula, the polyether polyol is used for replacing the traditional mixture of multiple polyethers, the viscosity of the paint can be reduced, and the performance of the polyurethane waterproof paint after film formation is improved.
Patent CN201410384281.5 discloses a synthetic method of polyether polyol for waterproof paint, which is prepared by adopting an alcohol compound and a physical medium to form a mixed initiator, polymerizing sodium methoxide and propylene oxide in the first stage under the conditions of 0-0.5Mpa and 50-150 ℃, polymerizing sodium hydride and ethylene oxide in the second stage, and finely treating with magnesium hexasilicate, aluminum silicate and an organic deodorant. The prepared polyether polyol has low potassium sodium ions, low odor and narrow molecular weight distribution, and the composite coating prepared based on the polyether polyol has the advantages of improving the performance of polyurethane spraying and coating, being environment-friendly and durable, and enhancing the competitiveness of the product. There is no case of using polyester ether polyol in the aspect of polyurethane waterproof coating.
Disclosure of Invention
The invention aims to solve the technical problems that: the polyester ether polyol for the high-performance polyurethane waterproof coating has excellent hydrolysis resistance and mechanical strength, and simultaneously has better flexibility, low temperature resistance and higher bonding strength, so that the polyurethane waterproof coating has excellent performance; the invention also provides a preparation method thereof, which is suitable for industrial mass production.
The invention relates to a preparation method of polyester ether polyol for high-performance polyurethane waterproof paint, which adopts low molecular weight polyether polyol with functionality of 2 and 3 as a mixing head, and after being compounded with anhydride, double metal cyanide complex is used as a catalyst to carry out segmented polymerization with alkylene oxide, and finally 3-5 polyester ether polyols with equal molecular weight intervals and normal distribution of mass are obtained by adopting a segmented discharging mode.
In the present invention, the low molecular weight polyether polyols having functionalities of 2 and 3 have a molecular weight of 300 to 1000.
The molar ratio of the low molecular weight polyether polyol with the functionality of 2 to the low molecular weight polyether polyol with the functionality of 3 is 9:1-1:1.
