    摘要: Disclosed are a preparation method and application of a 4-methyl-5-vinylthiazolyl polymerized spherical ionic liquid catalyst. The method comprises: preparing a functional ionic liquid monomer successfully by taking 4-methyl-5-vinylthiazole as the matrix, and preparing the polymerized spherical ionic liquid from the monomer. The catalyst combines the advantages of both ionic liquid and the polymer, and has the characteristics of large specific surface area, high catalytic activity, high mass transfer rate, good selectivity, high stability, easy recycling and separating, environmental friendliness, wide industrial application prospect, etc. The spherical ionic liquid is made into a novel catalytic packing and then put into a reactive distillation column for continuous reactive distillation of esterification and transesterification to realize the organic combination of the ionic liquid and the reactive distillation technology, achieving good catalytic activity, high product yield, environmental friendliness, and low corrosivity, which has great significance in realizing an environment-friendly process.

    摘要: A fiber-reinforced rigid polyurethane foam composite railway sleeper with high fiber content and a manufacturing method thereof are disclosed. The railway sleeper is formed by bonding a plurality of fiber-reinforced rigid polyurethane foam composite boards with high fiber content (10) by a binder (11), and the outer surface of the railway sleeper is provided with an anticorrosive paint film (12). The fiber-reinforced rigid polyurethane foam composite boards with high fiber content (10) include a polyurethane resin as a matrix material and a fiber as a reinforcing material. In the present invention, the problem of insufficient impregnation of the polyurethane and the fiber is solved by using a plurality of technical means such as using a mixed polyether polyol having a low hydroxyl value and a low functionality, using a coupling agent, etc., thus the fiber content is increased and a fiber-reinforced rigid polyurethane foam composite product having a density higher than 840 kg/m 3 and a fiber content greater than 60% is capable of being manufactured, which fills in the technical gap of fiber-reinforced rigid polyurethane foam composite railway sleepers and makes a diversification of the product specifications and performance to meet various technical requirements.
