Along with understanding and the attention of people to environmental protection; find that fluorochlorohydrocarbon has destruction to atmospheric ozone layer; international community has formulated multi-section environment pact, and China has also added the ranks of protection environment, and environment requirements of convention China eliminated before 2010 and destroys the atmospheric ozone layer material.In electron trade, the ROHS of European Union instruction, required in 2007 non-halogen, therefore, for meeting the need of market environment-friendly cleaning agent research and development and make the process of just accelerating.The halogen clean-out system that adopts is as the substitute of fluorochlorohydrocarbon, mainly by lower boiling, low-flash solvent compositions such as alcohols, ketone, ester class, alkanes, for example ethanol, Virahol, acetone, ethyl acetate, toluene, hexane etc. at present.Such clean-out system cost is low, cleaning-drying is fast, but its shortcoming is: cleaning performance is not as fluorochlorohydrocarbon, and flash-point is low, and is inflammable and explosive, and some is also toxic simultaneously, and volatility is big, healthy unfavorable to environment and operator.Therefore operating environment requires height, otherwise potential safety hazard is bigger, and it is improper to control, and security incident happens occasionally.
Therefore the good halogen SMT Printing screen clean-out system of safety performance is developed in people's expectation.
Summary of the invention
The purpose of the embodiment of the invention be not contain damage the ozone layer material, halogen, no flash-point, pH value for neutral, security is good, not volatile, can be recycled, cost is low, is applied to the aqueous cleaning agent of SMT Printing screen.
The embodiment of the invention is achieved in that
A kind of aqueous cleaning agent of SMT Printing screen, the main solvent that contains 5～35wt%, the solubility promoter of 1～10wt%, the tensio-active agent of 0.05-0.5wt%, surplus is a deionized water, main solvent is the esters solvent of halogen binary organic acid, and solubility promoter is a halogen polyalcohols solvent, and tensio-active agent is the halogen nonionogenic tenside.
Technique scheme, because the esters solvent that adopts the halogen binary organic acid is as main solvent, adopt halogen polyalcohols solvent as solubility promoter, tensio-active agent is the halogen nonionogenic tenside, like this, to have superpower solvent diester kind solvent with it the bad deionized water of intermiscibility by the effect of solubility promoter and tensio-active agent, be combined into homogeneous neutral water based cleaning agent, not only bring into play the dissolution characteristics of solution but also embodied the no flash-point of water, the characteristic that security is good, can be effectively applied to red glue on the SMT Printing screen, the cleaning of tin cream, the cleaning of tin cream on the wrongly typed circuit card, and the cleaning of PCBA residue, its cleaning way can adopt ultrasonic wave or spray mode.
