Description
Technical field
The present invention relates to a kind of universal cleaning liquid, particularly a kind of neodymium-iron-boron magnetic material processing degumming cleaning liquid.
Background technology
Neodymium-iron-boron magnetic material, as the latest result of rare earth permanent-magnetic material development, because its excellent magnetic property is called as " magnetic king ".Neodymium-iron-boron magnetic material is neodymium, the alloy of iron oxide etc.Claim again magnet steel.Neodymium iron boron has high magnetic energy product and strong power, the advantage of high-energy-density is applied widely Nd-Fe-Bo permanent magnet material in modern industry and electronic technology simultaneously, thereby makes miniaturization, lightweight, the slimming of the equipment such as instrument and meter, electroacoustic motor, magnetic separation magnetization become possibility.The advantage of neodymium iron boron is that cost performance is high, the mechanical property that tool is good; Weak point is that Curie point is low, and temperature characterisitic is poor, and is easy to efflorescence corrosion, must, by adjusting its chemical composition and taking surface treatment method to make it to be improved, just can reach the requirement of practical application.Magnetic material neodymium iron boron is emerging permanent-magnet material, its advanced machining technology, in constantly developing, is used the glue such as epoxy resin to fix in process, but the glue such as epoxy resin but exist and are difficult to clean after machining, scavenging period is long, and the high problem of energy consumption.
In prior art, magnetic material neodymium iron boron generally at high temperature cleans for a long time, can exert an influence like this to magnetic, also can cause workpiece surface damage, causes follow-up plating in conjunction with not firm, and learies is increased, and finally causes economy and resources loss.If add rare earth metal, there will be oxidation stability to reduce, material is easy to get rusty, and adds the variation of environmental consciousness, and the transformation from oiliness working fluid to aqueous machining fluid in process, to cleaning anti-oxidant proposition requirements at the higher level.
Therefore, need a kind of cleaning fluid that is applicable to magnetic material neodymium iron boron processing use, not only do not there is inflammable and explosive characteristic, and can not cause larger harmful effect to working environment, there is good Safety and Environmental Protection,, to processing oil and fixing glue, can efficiently clean fast meanwhile, and there is certain antioxidant effect.
Summary of the invention
In view of this, the object of this invention is to provide a kind of suitable neodymium-iron-boron magnetic material processing degumming cleaning liquid, not only do not there is inflammable and explosive characteristic, and to working environment, can not cause larger harmful effect, there is good Safety and Environmental Protection, improve processing environment and sanitary condition, to processing oil and fixing glue etc., can efficiently clean fast and thoroughly simultaneously, be beneficial to and increase work efficiency, reduced cost, reach the saving of economy and resource.
Degumming cleaning liquid is used in neodymium-iron-boron magnetic material processing of the present invention, and cleaning fluid raw materials by weight comprises following component: the water of dihydroxylic alcohols 1-30%, 0.005-0.1% complexing agent, anion surfactant 1-10%, non-ionic surface active agent 1-10%, composite corrosion inhibitor 1-10%, alkaline agent 2-10% and surplus adds to 100%;
Further, cleaning fluid raw materials by weight comprises following component: the water of dihydroxylic alcohols 7%, 0.05% complexing agent, anion surfactant 5%, non-ionic surface active agent 5%, composite corrosion inhibitor 8%, alkaline agent 2-10% and surplus adds to 100%;
Further, described dihydroxylic alcohols is one or more the mixture in ethylene glycol, propane diols, butanediol, hexylene glycol;
