【摘要】 替代造成白色污染的塑料产品，发展绿色环保产业，是社会进步的需要，发展的趋势；而目前用于纸张防油的产品，依赖进口，价格太高，成为国内发展绿色环保产业的障碍；所以本课题希望利用国产的原料，生产出替代进口的防油剂，来促进环保产业的发展，减轻白色污染。 本文研究了利用国产含氟单体，利用乳液聚合合成具有防油防水双效功能的中性施胶剂，并对合成产品进行了表征，初步摸索了其适宜的应用工艺条件。研究结果如下： ①通过单因素条件实验，找到合适本课题核心单体丙烯酸六氟丁酯和甲基丙烯酸六氟丁酯适宜使用的乳化剂体系为AES和OP—10等比搭配的复配乳化体系；过硫酸铵是本乳液聚合体系中较为适宜的引发剂。 ②通过正交实验，找出合成双效自定型施胶剂的适宜工艺条件为：反应单体丙烯酸六氟丁酯和甲基丙烯酸六氟丁酯的比例40：60；使用AES和OP—10等比复配的乳化剂总用量为2％；引发剂为2％过硫酸铵；温度70℃。 ③利用凝胶渗透色谱对施胶剂高分子的分子量及其分子量分布进行了测量，发现该氟碳共聚物分子量适中，分子量分布规则，有利于其在纤维上的吸附，并发挥良好的施胶作用。广西大学硕士学位份次·防油防水双效白定型中性施胶钊的合成及应用 ④利用扫描透射电镜和激光粒度分析仪，对合成的乳液观察粒径的分布状态、颗粒大小，说明乳液聚合后的施胶剂具有很好的分散性，颗粒的大小也比较均匀，这些都有利于乳液的稳定性。 ⑤利用红外光谱和核磁共振波谱分析该施胶剂高分子的结构性能，对氟碳共聚物的组成进行了分析，结果表明，两种共聚单体的特征吸收峰在谱图中都有出现，也可以说明，共聚单体进入了氟碳共聚物的分子链段。 ⑥从X一衍射的分析结果来看，合成的氟碳共聚物有较高的结晶度，这对于施胶剂的防油、防水性能是非常有利的。 ⑦通过应用实验确定适宜的施胶条件:施胶剂乳液用量为10%左右比较合适，打浆度280SR;pH值6.0;阳离子聚丙烯酞胺用量0.1%。施胶剂加热条件为:120℃的温度下，保温12分钟。更多还原

【Abstract】 It has been a trend to protect our environment by using paper product. Since the paper is unresisted to all kinds of liquid. We have to use many chemical materials to get the effect of proof-oil and proof-water, which are imported from abroad with high price. So my subject was be focused on a new kind of sizing agents, which will be based on domestic chemical materials.This paper describes a study about the synthesis of self-fixed sizing agent and gives a detailed example about this kind of proof-oil and proof-water sizing agent’s practical operation. The study focuses on the condition of emulsion polymerization and the proportions of monomer, which can make the product, not only have a nice waterproof and oilproof attribute but also have a better stability of emulsion. At the same time we try to find a better way to use this agents.The results of this research are shown as following: (1)Through the single condition test, we felt that the emulsion system is asuitable initiator for such a reaction by using AES:0P-10 (in proportion to 1:1)and NH4S2O4. (2)Through orthogonality experiments, the optimized condition in synthesizingsizing as follows: the proportion in reaction monomer between F and M-F is40:60, the total quantity using AES and OP-10 as emulsion is 2%, NH4S2O4as initiator is 2% ; temperature is 70 C. From the measurement polymer molecular weight and its molecular distribution of sizing agent with GPC methods, conclusions can be drawn as followed : the molecular weight of fluorocarbon compound is moderate, molecular weight distribute regular. All of those increase its adsorption in fibre. Then , it will have prefect performance of sizing. Analyzing particle situation and dimension of the synthesizing emulsion with TEM and LS methods. We would know that emulsion be of good distribution capacity, particle size be of uniform distribution, Which can indicate that emulsion be of fine stability. Analyzing the polymer structure’ s feature with IR and NMR for the composition of fluorocarbon compound, the charts indicate that the adsorption peak of two co-polymer monomer appearing in the spectrum. In other words, co-polymer monomer connected with fluorocarbon compound each other.The experiments of X- Diffraction indicate that fine degree of crystalline density will promote the proof-oil and proof-water capability. The optimized condition for the sizing processing as follow: the quantity of sizing agent is 10%, beating degree is 28癝R, pH 6.0, quantity of APAM is 0.1%. The heating conditions of sizing agent is heat preservation 12 minute at 120C.更多还原
