Abstract
The present invention relates to water soluble fluxes which comprise at least one wax carrier, at least one surfactant and at least one activator. The present water soluble fluxes are easily applicable with a brush. They have excellent pull through of solder in the joint. The water soluble flux avoids turning copper green and does not burst into flame on heating with a torch.
Claims (18)
1. A water-soluble flux composition comprising:
(A) a wax carrier having a melting point from about 55°C to about 150°C, (B) at least one surfactant, and (C) at least one activator.
(A) a wax carrier having a melting point from about 55°C to about 150°C, (B) at least one surfactant, and (C) at least one activator.
2. The composition of claim 1 wherein the wax carrier is a fatty carboxylic acid wax or derivative thereof.
3. The composition of claim 1 wherein the wax is selected from castor wax, synthetic bees wax, polyethylene glycol pentaerythritol tetrastearate, sorbitan tristearate, and polyethylene glycol trihydroxystearin.
4. The composition of claim 1 wherein the wax carrier (A) is present in an amount up to 10%.
5. The composition of claim 1 wherein the surfactant (B) is present in an amount from about 25% to about 75% by weight.
6. The composition of claim 1 wherein the surfactant (B) comprises polyoxyalkylene carboxylic acids, polyoxyalkylene carboxylic esters, polyoxyalkylene alcohols, polyoxyalkylene amines, polyalkylene glycol, alkoxylated fatty oils and mixtures of two or more thereof.
7. The composition of claim 1 wherein the activator (C) is present in an amount from about 0.5% to about 20%.
8. The composition of claim 1 wherein the activator (C) is selected from a salicylic acid, betaine hydrochloride, glutamic acid, glutamic acid hydrochloride, zinc chloride, ammonium chloride, and a hydroxy amine salt.
9. The composition of claim 1 wherein the activator is a hydrochloride salt of an alkanol amine.
10. The composition of claim 1 further comprising water.
11. The composition of claim 10 wherein the water is present in an amount from about 5% to about 28%.
12. A water-soluble flux composition comprising:
(A) a wax carrier having a melting point from about 55°C to about 150°C, (B) at least one surfactant, and (C) at least one activator.
(A) a wax carrier having a melting point from about 55°C to about 150°C, (B) at least one surfactant, and (C) at least one activator.
13. A water soluble flux comprising (A) castor wax, (B) at least one surfactant, and at least one activator.
14. The composition of claim 13 wherein castor wax is present in an amount from about 1% to about 8% by weight.
15. The composition of claim 1 wherein the surfactant (B) comprises polyoxyalkylene carboxylic acids, polyoxyalkylene carboxylic esters, polyoxyalkylene alcohols, polyoxyalkylene amines, polyalkylene glycol, alkoxylated fatty oils and mixtures of two or more thereof.
16. The composition of claim 1 wherein the activator (C) is selected from a salicylic acid, betaine hydrochloride, glutamic acid, glutamic acid hydrochloride, zinc chloride, ammonium chloride, and a hydroxyamine salt.
17. The composition of claim 13 further comprising water.
18. A method of soldering pipes, comprising the steps of providing a plurality of pipes one of which is coated with the flux composition of claim 1, bringing the pipes into contact where the portion of the pipes with the flux composition contacts the other pipe, and apply heat.
