- step (1) (2) heating and melting the selected part by weight of the thermoplastic resin binder, and adding the dense aggregate after heating in step (1) to obtain a stable coating material;
- the amount of water added is 2.5 to 5% by weight of the dense aggregate.
- the dense aggregate is first heated to 160 ° C or higher to 1000 ° C, and then cooled to 90-160 ° C.
- the invention also discloses an application of the oxygen release fast curing repairing material in the road surface repair engineering.
- the invention also discloses a method for quickly repairing damaged road surface by using the combustion method, comprising the following steps:
- step (1) after the step of filling the oxygen-dissipating fast-curing repairing material into the damaged pavement depression, further comprising the step of filling the upper layer with the self-compacting fast-curing repairing material; the self-compacting
- the fast curing repairing material is prepared from the following components by weight: 60-95 parts of compact aggregate; 4 to 30 parts of a thermoplastic resin binder; 1-10 parts of a thermally-initiated latent curing agent which can induce rapid curing of the thermoplastic resin binder in a heated state.
- the self-compacting fast curing repairing material is prepared from the following components by weight: 85-94 parts of compact aggregate; 5-10 parts of thermoplastic resin binder; thermally induced latent curing agent 1-5 Share.
- the optional components of the compact aggregate, the thermoplastic resin binder, and the thermally induced latent curing agent used in the self-compacting fast curing repairing material are the same as those used in the foregoing oxygen-storing fast-curing repairing material, and each The component properties and characteristics are also the same as the oxygen-storing fast-curing repair material.
- the thermoplastic resin binder includes one or more of a thermoplastic phenol resin, a boron phenol resin, a silicone-modified epoxy resin, a phenol-modified epoxy resin, or a urea-formaldehyde resin.
- the thermally initiated latent curing agent comprises urotropine (formal name: 1,3,5,7-tetraazatricyclo[3.3 ⁇ 1]decane), dicyandiamide, hydrazide, ammonium chloride or One or more of special modified curing agents.
- the dense aggregate includes silica sand particles, ceramic sand, ceramsite, small steel balls or small iron balls.
- the dense aggregate has a specific gravity of 1.7-8.9.
- the dense aggregate has a particle size of 20-200 mesh.
- the invention also provides a method for preparing the above self-compacting fast curing pavement repairing material, comprising the following steps:
- thermoplastic resin binder (2) adding a selected part by weight of the thermoplastic resin binder to the dense aggregate, and stirring uniformly;
- step (3) adding heat to the latent curing agent to the reactant obtained in the step (2), and stirring and then cooling the mixture; (4) The reactant obtained in the step (3) is cooled, crushed and sieved to obtain.
- step (1) the step of backfilling the damaged concrete to the damaged position and finishing the flattening is further included.
- the oxygen-releasing fast curing repairing material mainly comprises thermosetting phenolic resin, boron phenolic resin, silicone modified epoxy resin, phenolic modified epoxy resin, urethane resin, etc., high temperature resistance and strength
- the high specific polymer resin is used as the main coating reactant to prepare the coated silica sand composite materials with different particle sizes, and the heat-induced latent curing agent is added on the basis of the coating material and the oxygen can be released under the heated state.
- An oxidant additive material that releases oxygen upon heating to support the combustion exotherm of the combustible material to provide the heat required to cure the repair material;
- the latent curing agent wrapped on the surface of the dense aggregate will decompose the active intermediate, and the thermoplastic resin wrapped on the surface of the dense aggregate is also softened and flowed by heat, and finally latent curing
- the active substance released by the agent will chemically react with the resin, cross-linking and solidifying, and the film-forming resin will change from the original thermoplastic linear structure to the thermosetting body structure, and the final coated silica sand will be heated and formed within 50-70 minutes after heating.
- the high-strength pavement substrate greatly shortens the time for rushing and curing;
- the dense aggregate is silica sand particles, ceramic sand, ceramsite, small steel ball, or small iron ball with a certain weight and particle size, which can meet the requirements of self-compacting performance of the repairing material during road repair. Large particulate materials also help to increase the cure strength while saving material;
- the ratio of the thermoplastic resin binder to the thermally induced latent curing agent is 4-30: 1-10, more preferably 5-10: 1-5, which can ensure The better ratio of mixing and at the same time triggering the curing effect is better, ensuring the curing strength and shortening the curing time, and meeting the requirements for the repair time and the repairing strength in the road repairing project;
- the dense aggregate is an inert material and has poor adhesion to the polymer material.
- the process of the present invention first mixes the thermoplastic resin binder with the dense aggregate, and is similar to The principle of film coating makes the overall bonding performance of the repairing material better, and then the heat is combined with the heat-initiated latent curing agent to help strengthen the strength of the repairing material;

Description
一种可放氧快速固化修补材料及其制备方法与应用 技术领域 本发明属于铸造材料领域，具体涉及一种受热可放氧且可快速固化的 修补材料及其制备方法， 以及在快速抢修路面领域中的应用， 并具体涉及 一种利用受热可可放氧的修补材料结合燃烧法加热的快速抢修受损路面 的方法。 背景技术
随着我国经济的迅速发展，机场跑道数量迅速增加， 高等级高速公路 大量建设，城市广场及市政公路等混凝土工程的实施， 改善了人类的生存 质量，促进了国民经济的健康发展。现有的道路中采用混凝土施工路面的 较多， 不仅质量好而且使用寿命长。但是混凝土路面在使用中其路面损坏 后维修比较复杂， 需要封闭停用修复， 需要动用较大的机械才能将路面刨 开重新修筑， 同时养护期较长。 目前混凝土路面修补常用的修复材料有快 速水泥或沥青混凝土或高分子材料等，但都存在着需要长时间封闭路面修 整、 养护时间长等问题， 为道路抢修带来严重影响， 尤其是机场路面的抢 修就存在更大的问题。 中国专利 CN101121812A公开了一种环氧树脂基快速修补材料， 该修 补材料由砂石、 滑石粉、 环氧树脂、 聚酰胺和稀释剂组成。 该快速修补材 料可用于桥梁、 隧道、 道路和房屋等混凝土建筑的修补， 施工时仅需要对 混凝土表面进行处理，并对带裂缝构件则要作环氧树脂高压灌浆封缝处理 即可。 该修补材料施工方便、 工期较短（3天强度可达 60-70MPa )、 无需 封闭路面且早期强度较高、后期强度适中。但该材料用于修补路面时灌浆 后依然依靠自然养护， 而且需要养护 3天的强度才能达到 60-70MPa, 还
是需要短期封闭抢修， 而且以砂石等轻质砂石为骨料， 整个修补材料的自 密实性能较差， 在用于抢修路面时还需要进行填平处理， 对于类似机场路 面等需要快速抢修的路面修补并不适用。 现有技术中也有一些在路面抢修时通过外设的加热装置对快速修补 材料进行加热处理使得抢修时间缩短的手段，但通过外在设备加热的方法 一方面需要运输加热设备， 同时对于修补材料的全面加热范围也受到限 制。因此开发出一种可采用筒易方法加热固化的可用于快速修补路面的修 补材料及快速固化的修补方法成为该领域亟待解决的问题。 中国专利 CN101817663A公开了一种混凝土路面快速修补方法， 该方 法所使用的路面修补材料由偏高岭土、矿渣、水泥等粉料，砂、石等集料， 以及水玻璃制备而成的。道路修补时将修补材料浇注于清理过得破损路面 处， 并震动、 抹平、 自然养护 8小时即可， 避免了普通修补材料需要养护 3-7天、封路期限较长、 影响交通的问题。 但是该方法采用的是自然养护， 虽然修补材料的固化性能较好，但仍需要 8小时的养护期， 对于机场等急 需快速抢修的道路并不适用。 发明内容 为此，本发明所要解决的技术问题在于现有技术中用于路面抢修的材 料不适用于快速固化的方法， 进而导致抢修时间较长的问题， 进而提供一 种可放氧且可快速固化的修补材料。
