为解决传统酚醛泡沫（PF）在煤矿充填堵漏过程中释放甲醛的问题。本文通过在PF合成后加入含有氨基化合物的甲醛捕集剂，研究了不同因素对甲醛捕集剂效率的影响。考察了甲醛捕集剂对树脂性能的影响。结果表明，甲醛捕集剂的加入可以大大降低酚醛树脂中的残留甲醛含量。傅里叶变换红外光谱（FTIR）数据表明，甲醛捕集剂的加入不仅成功制备了PF，而且生成了稳定的甲醛捕集剂产品。与未改性的PF相比，改性PF的孔径和发泡率均有不同程度的降低，发泡温度也有不同程度的降低。其中，脲改性酚醛树脂（PUF）的甲醛去除效率最高。它在燃烧过程中具有最低的热释放，并且泡沫孔径大且均匀。此外，通过尿素改性PF在采空区回风角缝封堵应用中的应用，发现采空区CO浓度保持在0.002%的最低状态。达到了高分子瓦斯封堵材料国家行业标准，符合煤矿防火领域的绿色发展理念。脲改性酚醛树脂（PUF）的甲醛去除效率最高。它在燃烧过程中具有最低的热释放，并且泡沫孔径大且均匀。此外，通过尿素改性PF在采空区回风角缝封堵应用中的应用，发现采空区CO浓度保持在0.002%的最低状态。达到了高分子瓦斯封堵材料国家行业标准，符合煤矿防火领域的绿色发展理念。脲改性酚醛树脂（PUF）的甲醛去除效率最高。它在燃烧过程中具有最低的热释放，并且泡沫孔径大且均匀。此外，通过尿素改性PF在采空区回风角缝封堵应用中的应用，发现采空区CO浓度保持在0.002%的最低状态。达到了高分子瓦斯封堵材料国家行业标准，符合煤矿防火领域的绿色发展理念。结果发现，采空区CO浓度维持在0.002%的最低状态。达到了高分子瓦斯封堵材料国家行业标准，符合煤矿防火领域的绿色发展理念。结果发现，采空区CO浓度维持在0.002%的最低状态。达到了高分子瓦斯封堵材料国家行业标准，符合煤矿防火领域的绿色发展理念。

Study of preparation and properties of environmentally friendly phenolic resin for mining

In order to solve the problem of formaldehyde release from the traditional phenolic foam (PF) in the process of coal mine filling and plugging. In this paper, the effect of different factors on the efficiency of formaldehyde trapping agents were studied by adding formaldehyde trapping agents containing amino compounds after PF synthesis. The effect of formaldehyde trapping agents on the performance of resin was investigated. The results showed that the addition of formaldehyde trapping agents could greatly reduce the residual formaldehyde content in phenolic resin. Fourier-transform infrared spectroscopy (FTIR) data showed that the addition of formaldehyde trapping agent not only successfully prepared PF, but also produced a stable formaldehyde trapping agent product. Compared with the unmodified PF, the pore size and foaming rate of the modified PF decreased in varying degrees, and the foaming temperature also decreased in varying degrees. Among them, urea modified phenolic resin (PUF) had the highest formaldehyde removal efficiency. It had the t lowest heat release during combustion and the foam pore size was large and uniform. In addition, through the application of urea-modified PF in the goaf return air corner fissure sealing application, it was found that the CO concentration in the goaf maintained at the lowest state of 0.002%. It has reached the national industry standard of polymer gas plugging materials and conforms to the green development concept in the field of coal mine fire prevention.
