Description
技术领域
本发明涉及一种水性金属加工液，主要应用于有色金属或黑色金属加工零件的切磨钻削工艺。
背景技术
用全合成和微乳化替代乳化液已经是全球不争的事实，其最根本的原因是环保和节能的要求。众所周知，油基切削液的润滑性能和防锈性能比水基切削液好；水基切削液的冷却效果却明显优于油基切削液。乳化液把油的润滑性和防锈性与水的冷却性结合起来，因而对产生热量较大的高速低压力的金属切削加工很有效。在高速切削时，由于发热量大，油基切削液的散热效果差，会使切削区的温度过高进而产生烟雾、起火等现象。此外，由于工件温度过高易产生热变形，影响工件加工精度，所以水基乳化切削液成为金属加工液的最主要角色。但是乳化液的缺点也相当明显：乳化液中含有40%--80%基础油以及低级胺、极压剂是微生物的营养源，易于细菌、真菌的大量繁殖，微生物的繁殖代谢使乳化液中的有效成分降低、pH值降低、加工液发臭变质，如果继续使用需要不断加入杀菌剂进行维持，但此种方案不利于操作者的卫生和安全；如果不再使用腐败的加工液，需要进行全更液，将废液进行处理才可以进行排放，但此种方案不利于环保和节能的需求。
目前，金属加工行业内全面以半合成、全合成切削液代替了传统的乳化液。化学合成切削液的优点在于经济、散热快、清洗性强和极好的工件可见性，易于控制加工尺寸，以及使用液的稳定性和抗腐败能力。但是全合成水性加工液的产生主要是应对产热量较大的磨削加工（加工黑色金属材料）工艺，所以不适合铝合金的加工，从而限制了全合成液的应用范围；另外所谓全合成加工液的性能稳定性好和抗腐败能力强的前提条件为：加工液在使用过程中及时撇掉加工设备漏油，否则杂油将被乳化，使全合成液渐变为乳化液，但在实际使用过程中这个前提条件并不容易做到，从而使加工液的清洗性能和耐腐败性能变差。
发明内容
本发明的目的在于提供一种具有优良抗杂油性能、金属缓蚀性能良好的抗杂油、耐金属腐蚀、生物稳定型水性全合成加工液。
本发明的技术解决方案是：
一种抗杂油、耐金属腐蚀、生物稳定型水性全合成加工液，其特征是：由下列重量百分比的成分组成：
十一碳二元酸 4~9%
四甲基己二胺 2-6%
三异丙醇胺 2-6%
二苄胺 2-6%
2-氨基-2-甲基-1-丙醇 4-8%
苯并三氮唑 0.3-0.8%
D2000聚醚胺 0.3-0.8%
聚醚 6-10%
N-氨乙基-r-氨丙基三甲氧基硅烷 1-3%
聚乙烯亚胺 0.3-0.8%
聚醚改性聚硅氧烷消泡剂 0.3-0.8%
其余成分为水。
所述的抗杂油、耐金属腐蚀、生物稳定型水性全合成加工液，由下列重量百分比的成分组成：
十一碳二元酸 7.0%
四甲基己二胺 4.0%
三异丙醇胺 4.0%
二苄胺 4.0%
2-氨基-2-甲基-1-丙醇 6.0%
苯并三氮唑 0.5%
D2000聚醚胺 0.5%
聚醚 8%
N-氨乙基-r-氨丙基三甲氧基硅烷 2%
聚乙烯亚胺 0.5%
聚醚改性聚硅氧烷消泡剂 0.5%
其余成分为水。
1. 本产品采用苯并三氮唑、短链脂肪二元酸和硅系金属腐蚀抑制剂进行复配，可以显著提高对有色金属和黑色金属的耐腐蚀能力（有色金属腐蚀测试：55℃恒温24小时条件下紫铜测试片和ADC12铝测试片均不变色光亮如新；黑色金属腐蚀测试：室温24小时条件下铸铁切屑无锈点），所以此产品可对于有色金属或黑色金属的加工均可。
2. 本产品含有适量阳离子表面活性剂（聚乙烯亚胺），提高产品的抗杂油性能（抗乳化性能测试：40ml该产品稀释液中加入40ml现场用液压油或导轨油，高速搅拌5min后，混合液10min即可分离为油层和水层，无乳化层存在。），所以可抵抗外来杂油混入造成的有效成分降低、腐败加速等不良影响。
3. 本产品中加入生物稳定型成分异丙醇胺、四甲基己二胺、二苄胺进行复配，该成分不是杀死微生物，而是受微生物的攻击不会迅速的被分解，维持加工液的pH值稳定，从而避免微生物过度繁殖造成加工液有效成分的降解造成加工液性能的下降和寿命缩短的问题。（耐腐败性能测试：耐腐败测试30天开始生菌数103，测试至60天时生菌数仍为103）。
4. 配方不含重金属、芳香烃等有毒有害物质，生物半致死量LD50≥5000mg/kg，半致死浓度LC50≥5000mg/m3，无呼吸道粘膜刺激（0级），对人和环境友好。
