技术领域Technical Field
本发明涉及酚醛树脂领域，具体涉及一种合成酚醛树脂，以及用该酚醛树脂制备碳材料的方法。The invention relates to the field of phenolic resins, and in particular to a synthetic phenolic resin and a method for preparing a carbon material by using the phenolic resin.
技术背景technical background
酚醛树脂具有良好的耐酸性能、力学性能、耐热性能，广泛应用于防腐蚀、胶粘剂、阻燃材料等；并且酚醛树脂具有高残炭率，酚醛树脂在1000℃的惰性气体条件下会产生很高的残碳，产生的碳材料可以用于锌离子超级电容器的阴极材料。Phenolic resin has good acid resistance, mechanical properties, and heat resistance, and is widely used in anti-corrosion, adhesives, flame retardant materials, etc.; and phenolic resin has a high residual carbon rate. Phenolic resin will produce very high residual carbon under inert gas conditions at 1000°C. The produced carbon material can be used as the cathode material of zinc ion supercapacitors.
目前酚醛树脂的制备原理是酚类和醛类在酸性或者碱性的催化剂作用下，通过缩聚反应生成酚醛树脂。酚醛树脂使用的原料一般为苯酚和甲醛等。但苯酚有毒，它的浓溶液对皮肤有强烈的腐蚀性，使用时有很大的风险存在；并且甲醛对人体也有危害。At present, the preparation principle of phenolic resin is that phenols and aldehydes are reacted under the action of acidic or alkaline catalysts to generate phenolic resin through polycondensation reaction. The raw materials used for phenolic resin are generally phenol and formaldehyde. However, phenol is toxic, and its concentrated solution is highly corrosive to the skin, which poses a great risk when used; and formaldehyde is also harmful to the human body.
发明内容Summary of the invention
为了解决上述问题，本发明将常用原料苯酚和甲醛使用丹宁酸和五羟甲基糠醛代替，其中丹宁酸是一种生物质原料，普遍存在于葡萄、茶叶等植物中，并且含有大量的酚羟基；五羟甲基糠醛是由葡萄糖或者果糖脱水生成的化学物质，它的分子中含有高活性的醛基。使用丹宁酸和五羟甲基糠醛作为生产酚醛树脂的原料，可以有效地减少制备过程带来的污染和对人体的危害。制备得到的酚醛树脂基碳材料可用作锌离子超级电容器的碳阴极，并且表现出较好的性能。本发明碳材料用作碳阴极的锌离子混合超级电容器的电极测试表明，当功率密度达到731 W/kg时，比电容达到90.7 mAh/g，能量密度达到79 Wh /kg。In order to solve the above problems, the present invention replaces the commonly used raw materials phenol and formaldehyde with tannic acid and pentahydroxymethylfurfural, wherein tannic acid is a biomass raw material, which is commonly found in plants such as grapes and tea leaves and contains a large amount of phenolic hydroxyl groups; pentahydroxymethylfurfural is a chemical substance generated by dehydration of glucose or fructose, and its molecules contain highly active aldehyde groups. Using tannic acid and pentahydroxymethylfurfural as raw materials for producing phenolic resin can effectively reduce the pollution caused by the preparation process and the harm to the human body. The prepared phenolic resin-based carbon material can be used as a carbon cathode of a zinc ion supercapacitor and exhibits good performance. The electrode test of the zinc ion hybrid supercapacitor using the carbon material of the present invention as a carbon cathode shows that when the power density reaches 731 W/kg, the specific capacitance reaches 90.7 mAh/g and the energy density reaches 79 Wh/kg.
本发明酚醛树脂的制备方法如下：The preparation method of phenolic resin of the present invention is as follows:
（a）将丹宁酸、五羟甲基糠醛和纳米氧化镁按照质量比使用研钵充分研磨混合，研磨过程中加入少量稀硫酸催化后继续研磨至均匀。(a) Grind and mix tannic acid, pentahydroxymethylfurfural and nano-magnesium oxide in a mortar according to the mass ratio. Add a small amount of dilute sulfuric acid as a catalyst during the grinding process and continue grinding until the mixture is uniform.

进一步的，丹宁酸：五羟甲基糠醛：纳米氧化镁质量比为1:1:2。Furthermore, the mass ratio of tannic acid: pentahydroxymethylfurfural: nano-magnesium oxide is 1:1:2.
进一步的，稀硫酸用量为0.5mol/L。Furthermore, the amount of dilute sulfuric acid used is 0.5 mol/L.
进一步的，步骤（b）中的反应条件为：在180℃下反应12小时。Furthermore, the reaction conditions in step (b) are: reacting at 180° C. for 12 hours.
用本发明酚醛树脂基材料制备酚醛树脂碳材料的方法，具体制备步骤如下：The method for preparing a phenolic resin carbon material using the phenolic resin-based material of the present invention comprises the following specific preparation steps:
①将酚醛树脂基材料移入石墨舟，氮气气氛下，升温直至900℃，保温1小时后，得到样品。① Move the phenolic resin-based material into a graphite boat, raise the temperature to 900°C under a nitrogen atmosphere, and keep it for 1 hour to obtain a sample.
②使用盐酸清洗样品，抽滤后置于烘箱中烘干，得到酚醛树脂碳材料。② The sample was washed with hydrochloric acid, filtered and dried in an oven to obtain a phenolic resin carbon material.
进一步的，步骤①升温速度为：2℃/min。Furthermore, the heating rate in step ① is 2°C/min.
进一步的，步骤②使用盐酸清洗样品时，使用的盐酸为：1mol/L。Furthermore, when hydrochloric acid is used to clean the sample in step ②, the hydrochloric acid used is: 1 mol/L.
进一步的，步骤②烘干条件为：置于60℃烘箱中烘6h。Furthermore, the drying condition of step ② is: placing in an oven at 60° C. for 6 hours.
