Description

抗叠片腐蚀型普通碳素钢板带冷轧轧制液
技术领域
本发明涉及一种抗叠片腐蚀型普通碳素钢板带冷轧轧制液,属于润滑油领域。
背景技术
普通碳素结构钢简称普碳钢,是指含碳量小于2.11%,并含有少量硅、锰、硫、磷等元素的钢材。按品种分类,用作板带材的普碳钢占比最高,且冷轧普碳钢板带的数量又多于热轧产品。冷轧是指在金属的再结晶温度以下对金属板带进行减薄轧制的工艺,不产生氧化铁皮,具有表面质量好、尺寸精度高的特点,再加之退火处理,其机械性能和工艺性能都优于热轧薄钢板。
普碳钢板带的冷轧加工过程具有轧制速度快、单道次压下量大的特点,所采用的轧制液多通过原液调配成冷却性能较好的乳化液,需要具备优异的润滑性以确保轧制过程的进行,并防止断带、划痕等情况的发生。
此外,在实际生产中,带钢从轧制完成到脱脂过程的进行,往往需要根据排产要求存放一定时间。在叠放过程中,叠片之间形成缝隙,缝隙中的腐蚀介质不容易排出,空气不容易流通,缝隙中的氧含量低于空气中的氧含量,构成氧浓差电池腐蚀。据报道,缝隙越小,腐蚀速率越大。如果对带钢进行额外的防锈处理,既增加工序,又提高了处理成本。
发明内容
为了克服现有技术的不足,本发明提供一种抗叠片腐蚀型普通碳素钢板带冷轧轧制液,除了在冷轧时润滑性能好以外,还使得冷轧后沾有该轧制液的钢带可直接叠片存放,不容易产生叠片腐蚀。
本发明解决其技术问题所采用的技术方案是:
一种抗叠片腐蚀型普通碳素钢板带冷轧轧制液,按质量包括以下组分:基础油67%-78%、极压剂8%-10%、油性剂6%-8%、乳化剂3%-5%、抗氧剂2%-3%、金属减活剂1%-2%、防锈剂2%-5%;所述防锈剂选自N-油酰肌氨酚十八胺盐和羟基乙叉二膦酸中的至少一种;所述金属减活剂为噻二唑衍生物、苯三唑衍生物、苯并三氮唑、甲基苯并三氮唑、甲基苯并三氮唑钠盐等中的一种;所述抗氧剂选自2,6-二叔丁基对甲酚、2,6-二叔丁基混合酚、三(壬基酚)亚磷酸酯、N,N-二乙基羟胺、环己胺、N,N-二仲丁基对苯二胺、烷基二苯胺、N-苯基-α-萘胺中的至少一种。
本申请提供的抗叠片腐蚀型普通碳素钢板带冷轧轧制液原液状态稳定,具有较好的抗氧化和抗菌效果,使用时需将原液按照1.5wt%-5wt%的浓度用水通过高速搅拌配置成乳化液,应用于冷轧时润滑效果好,轧制后附在带钢表面,抗氧剂、金属减活剂和防锈剂共同发挥防锈效果,能够抑制叠片腐蚀,无需对冷轧后的带钢进行额外的处理。

进一步地,所述油性剂选自妥尔油、脂肪酸甲酯、油酸、妥尔油脂肪酸、蓖麻油酸、椰子油酸、油酸季戊四醇酯、棉籽油、新癸酸中的至少一种。
更进一步地,所述油性剂为新癸酸和妥尔油脂肪酸的组合物,按质量计,在所述抗叠片腐蚀型普通碳素钢板带冷轧轧制液中,含有新癸酸2%-3%,含有妥尔油脂肪酸4%-5%。该油性剂的组合成本较低、润滑性能好、增溶性强,且在自来水配液的实际工况下,具有一定的抗硬水和抗泡性能。
进一步地,所述极压剂为磷酸酯铵盐、磷酰胺、硫化脂肪酸酯、硫代烯烃、二苄基硫醚中的至少一种。
更进一步地,所述极压剂为磷酸酯铵盐、硫化脂肪酸酯和硫代烯烃的组合物,在所述抗叠片腐蚀型普通碳素钢板带冷轧轧制液中,含有磷酸酯铵盐2%-2.5%,含有硫化脂肪酸酯4%-5%,含有硫化烯烃2%-2.5%。该极压剂的组合在实际轧制过程复杂的温度变化下具有优异的极压抗磨效果。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例,都属于本发明保护的范围。
应该理解的是,在不冲突的前提下,本发明的任一和所有实施方案都可与任一其它实施方案或多个其它实施方案中的技术特征进行组合以得到另外的实施方案。本发明包括这样的组合得到另外的实施方案。
除非另有规定,本文使用的所有技术术语和科学术语具有要求保护主题所属领域的标准含义。倘若对于某术语存在多个定义,则以本文定义为准。
针对现有技术的不足,有必要发明一种冷轧轧制油,在确保润滑性,保证碳钢板带轧制过程可顺利进行的前提下,同时具备高叠片状态下的防锈性,这将有助于保证碳钢板带轧制后长期叠片存放的质量。
本申请实施例提供一种抗叠片腐蚀型普通碳素钢板带冷轧轧制液。按质量计算,包括如下组分:基础油67%-78%、极压剂8%-10%、油性剂6%-8%、乳化剂3%-5%、抗氧剂2%-3%、金属减活剂1%-2%、防锈剂2%-5%。
该抗叠片腐蚀型普通碳素钢板带冷轧轧制液的制备步骤如下:
S1:将基础油混合,在50℃-55℃下搅拌至澄清透明。
S2:向步骤S1所得到的基础油混合液中依次缓慢加入油性剂、极压剂、抗氧剂、金属减活剂和防锈剂,搅拌至溶液澄清透明。
S3:向步骤S2所得到的混合溶液中,加入乳化剂,充分搅拌,得到琥珀色透明冷轧轧制液原液。
在使用时将原液按照1.5wt%-5wt%的浓度用水通过高速搅拌配置成乳化液。
作为含量最高的功能性组分,基础油可起到一定的润滑作用,并可作为油溶性添加剂的溶剂。基础油为椰子油、蓖麻油、菜籽油、棉籽油、棕榈油、大豆油等植物基础油中一种或几种,又或者是一类矿物基础油、二类矿物基础油、三类矿物基础油等矿物基础油中的一种或几种,还可以是植物基础油和矿物基础油的组合。优选地,基础油为蓖麻油和200SN基础油的组合物,按质量百分比计算(在原液中),蓖麻油为56%-65%,200SN为11%-13%。二者可互溶,可对其它添加剂有效溶解分散,在轧制过程中可形成均匀连续的油膜,确保优异的润滑、抗氧和溶解性能。
极压剂是一种在高温、高压等极端苛刻条件下与摩擦副表面形成极压润滑膜的重载荷添加剂。普碳钢轧制速度快、压下率高,轧辊与板带间作用力大,需要添加极压剂以满足润滑性能。极压剂为磷酸酯铵盐、磷酰胺、硫化脂肪酸酯、硫代烯烃、二苄基硫醚中的一种或几种。优选地,极压剂为磷酸酯铵盐、硫化脂肪酸酯和硫代烯烃的组合物。按质量百分比计算(在原液中),磷酸酯铵盐为2%-2.5%;硫化脂肪酸酯为4%-5%;硫化烯烃为2%-2.5%,通过复配,在实际轧制过程复杂的温度变化下具有优异的极压抗磨效果。
油性剂可通过极性基团吸附在摩擦面上,形成分子定向吸附膜,阻止金属互相接触,从而减少摩擦和磨损。此外,油性剂也具有亲油型乳化剂的功能。添加油性剂,可确保普碳钢板带轧制时常温常压部分的润滑效果。油性剂为妥尔油、脂肪酸甲酯、油酸、妥尔油脂肪酸、蓖麻油酸、椰子油酸、油酸季戊四醇酯、棉籽油、新癸酸中的一种或几种,优选地,油性剂为新癸酸和妥尔油脂肪酸的组合物,按质量百分比计算(在原液中),新癸酸为2%-3%,妥尔油脂肪酸为4%-5%。优选的油性剂成本较低、润滑性能好、增溶性强,且在自来水配液的实际工况下,具有一定的抗硬水和抗泡性能。
板带钢冷轧轧制液多按一定比例稀释为乳化液使用。为了确保轧制液可在水中形成乳化液,且在加工过程中乳化液可形成高强度润滑膜,需要向润滑剂中添加乳化剂。乳化剂为油醇聚氧乙烯醚、月桂醇聚氧乙烯醚、烷基酚聚氧乙烯醚、油酸聚氧乙烯醚、聚乙二醇油酸酯、司盘-80、吐温-80中的一种或几种,优选的,乳化剂为油醇聚氧乙烯醚,成本低、乳化性能好。
为了防止表面残有轧制液组分的普碳钢板带发生锈蚀,需要添加防锈剂,配合抗氧剂和金属减活剂使用,确保碳钢板带表面质量。防锈剂为N-油酰肌氨酚十八胺盐和羟基乙叉二膦酸的单质或组合物。按质量百分比计算(在原液中),N-油酰肌氨酚十八胺盐为0-5%,羟基乙叉二膦酸为0-5%,可确保普碳钢板在轧制到脱脂的过程中以密实钢卷的状态保存期间,钢板表面贴合受压的状态下,仍具有优异的防锈效果。
轧制过程中,高温、高压环境下油品的氧化会降低其品质、增大其消耗,且生成的酸性物质和水等杂质会使碳钢产生严重锈蚀。为了防止这一情况,向组合物中添加抗氧剂。抗氧剂为2,6-二叔丁基对甲酚、2,6-二叔丁基混合酚、三(壬基酚)亚磷酸酯、N,N-二乙基羟胺、环己胺、N,N-二仲丁基对苯二胺、烷基二苯胺、N-苯基-α-萘胺等中的一种或几种,优选地,抗氧剂为2,6-二叔丁基对甲酚和N,N-二乙基羟胺的组合物。按质量百分比计算(在原液中),2,6-二叔丁基对甲酚为1%-1.5%,N,N-二乙基羟胺为1%-1.5%。优选的抗氧剂具有良好的油溶性通过复配可具备较好的抗氧效果,除保证油品质量稳定外,也可与防锈剂协同作用,在钢板表面贴合受压的状态下增强防锈效果。
添加金属减活剂,配合抗氧剂使用,可进一步减缓油品的氧化,防止碳钢的锈蚀。金属减活剂为噻二唑衍生物、苯三唑衍生物、苯并三氮唑、甲基苯并三氮唑、甲基苯并三氮唑钠盐等中的一种。优选的,金属减活剂为甲基苯并三氮唑,具有较强的金属减活效果和良好的油溶性,可与防锈剂和抗氧剂协同作用,在钢板表面贴合受压的状态下增强防锈效果。
