Corner brace castable as well as preparation method and application thereof
The invention belongs to the technical field of high polymer materials, and discloses a corner brace castable as well as a preparation method and application thereof. The corner brace castable comprises a component A and a component B, the component A comprises polyester polyol, castor oil polyol, a catalyst and a modified composite filler, and the component B comprises isocyanate and organic amine; the modified composite filler is prepared by modifying carbon black, zinc oxide and silica powder with solid polyethylene glycol and a silane coupling agent. The carbon black, the zinc oxide and the silica powder are reasonably selected to be compounded and modified, so that the compatibility and the dispersity of the filler and a polyurethane resin matrix are improved, the advantages of the filler and the polyurethane resin matrix can be fully exerted, and the comprehensive properties such as the mechanical property, the thermal stability and the weather resistance of the polyurethane resin are improved; the corner brace castable disclosed by the invention is filled in a corner brace, and after the corner brace castable is cured and formed, strong support is provided for the corner brace, so that the corner brace is prevented from being deformed due to stress, and the strength of the corner brace can be obviously improved.
本发明属于高分子材料技术领域，公开了一种角码浇注料及其制备方法和应用。本发明角码浇注料包括A组分和B组分，A组分包括聚酯多元醇、蓖麻油多元醇、催化剂和改性复合填料，B组分包括异氰酸酯和有机胺；改性复合填料为炭黑、氧化锌和硅微粉经过固体聚乙二醇、硅烷偶联剂改性制得的改性复合填料。本发明通过合理选择炭黑、氧化锌和硅微粉这三种填料复配，并进行改性，使得填料与聚氨酯树脂基体的相容性提高，分散性提高，可以充分发挥它们的优势，提高了聚氨酯树脂的力学性能、热稳定性和耐候性等综合性能；将本发明角码浇注料填充于角码中，固化成型后，对角码提供强力的支撑，避免角码因受力而出现变形，能够明显提高角码的强度。
