Low-temperature curing high-strength precoated sand material and preparation method thereof
The invention mainly aims to provide a low-temperature curing high-strength precoated sand material and a preparation method thereof, and aims at solving the problems in the prior art. The low-temperature curing high-strength precoated sand material comprises a component A and a component B, the component A comprises quartz sand, resin and a curing agent; the component B comprises a modified curing agent; and the mass fraction of the component A in the sand prevention material is 60%-80%, and the mass fraction of the component B in the sand prevention material is 20%-40%. According to the precoated sand material disclosed by the invention, the quartz sand is subjected to resin coating treatment and is compounded with the modified curing agent, so that the precoated sand material can be solidified underwater, the curing speed is high, the solidification strength is high, and the underwater stability can be kept for a long time.
本发明主要目的是针对现有技术问题，提供一种低温固化高强度覆膜砂材料及其制备方法，包括A、B组分；A组分包括石英砂，树脂和固化剂；B组分包括改性固化剂；在所述防砂材料中A组分的质量分数为60％‑80％，B组分的质量分数为20％‑40％。本发明所述覆膜砂材料通过对石英砂进行树脂覆膜处理，与改性固化剂复合使用，可以在水下固结，固化速度快，固结强度高，并且能够长久保持水下稳定。
