Abstract

The invention relates to a soldering iron tip maintenance block which is composed of the compositions according to the weight percentage of 0 to 50 percent of organic dibasic acid, 0 to 20 percent of alumina powder or sic powders, 0 to 20 percent of borax, 0 to 5 percent of glycol, 0 to 5 percent of maleic anhydride, the rest of the composition is ammonium chloride. The invention has the advantages that: the soldering iron tip can be cleaned and restored, the service life is prolonged, and the copper resources are saved substantially. The process of cleaning and repairing the soldering iron tip is easy and convenient by inserting the soldering iron tip in the maintenance block undergoing reciprocating friction, feeding appropriate proportion of solder to ensure the solder to wet wounded surface, thereby, labor and time are saved and the work efficiency is improved consequentially. The whole structure is environmentally-friendly and meets the requirements of environment protective.

Description

Welding head maintenance block

Technical field

The present invention relates to a kind of chemical composition, particularly a kind of have cleaning and the welding head maintenance block of repairing maintenance function to welding head.

Background technology

Flatiron is as the instrument of scolding tin soldering, the use history of existing centuries, from Germany more than 100 year before invention first electric iron so far, the making of electric iron has been gone through many generations and has been improved, in electronics and IT products and electrical equipment household appliances, the electric installation assembling, electric iron is still using in large quantities in above-mentioned field now.Because the thermal conductivity of the excellence of copper and to the good wetting ability of scolding tin, alloy welding head copper or the copper base has become the most economical and effective welding head and has made material.But in using following practical difficulty is arranged also, welding head work-ing life and efficient are reduced greatly.The enforcement of environmental protection bills such as the RoHS of European Union; there is lead solder thoroughly to be banned use of; original having in the lead solder; because the existence of high-content lead is arranged; plumbous can effectively stop copper dissolution on the welding head in scolder; Pb-free solder then has very strong dissolving power to copper; a general small-sized welding head that on streamline, uses; mean lifetime has only 2-3 hour, and same welding head is welded with lead welding tin, and mean lifetime has 2-3 days; terms of settlement is preferably: one; from the solution of starting with of the making material structure of welding head, its two, be to adopt effectively to protect the welding head material.Present technique invention usefulness be second kind of terms of settlement.

The heat waste of welding head mainly shows three aspects: the first surface oxidation, because the existence of surface oxide layer makes welding head no longer have wetting ability to tinsolder.The secondth, be heated carbonization and tinsolder oxide compound of soldering flux accumulates in the welding head surface in the flatiron hot work, the flatiron in the use and then again dirt is brought into, and pollute welded article spare, and influence flatiron continuation operation.The 3rd is that erosion is melted by tinsolder in surface, welding head tip, makes the flatiron tip damaged or empty, can't continue to use.The terms of settlement of current custom is 1. old welding head to be abandoned, and changes welding head again.2. repair with file filing welding head, until can't continue the file repair till.More than two kinds of ways all can not make things convenient for and clean and repair welding head timely, it is time-consuming costly again, very uneconomical that these repair welding head methods, will discard welding head in large quantities, wasted valuable copper resource again.

Summary of the invention

Technical problem to be solved by this invention provides a kind of welding head maintenance block, makes it can clean and repair impaired welding head easy, effectively, and environmentally friendly.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

Welding head maintenance block, form by following components in weight percentage:

Organic dibasic acid 0-50%

Aluminum oxide powder or carborundum powder 0-20%

Borax 0-20%

Ethylene glycol 0-5%

MALEIC ANHYDRIDE 0-5%

The ammonium chloride surplus.

Said components is mixed suitable heating formed stool can be made into maintenance block.During use, the welding head of needs reparation is placed on reciprocating friction on the maintenance block, feeds simultaneously and make for an amount of scolding tin to be subjected to the surface of a wound can wetting scolding tin, just can effectively clean and repair welding head and impaired welding head is returned to normal condition.

The effect of each component is explained as follows among the present invention:

Ammonium chloride is owing to have fine fluxing action to metal oxide, and the N2 of its pyrolysis abrupt release and H2 have reducing metal oxide and protection copper surface simultaneously, stop its oxidized function.

Organic dibasic acid can effectively be gone back the oxide compound of native copper and tin, makes welding head revert to fresh metallic surface.

Aluminum oxide or carborundum powder can be used as the abrasive composition, make welding head obtain grinding effect preferably when the maintenance block surface friction, melt the hole and are in time repaired with the Wicresoft of removing the welding head surface, and be easy to wipe the carbonization pollutent on surface.Preferably use particle diameter less than 50 purpose powder.

Borax has the fusion of help metal oxide and cleaning surfaces function simultaneously, and helps soldering iron tip and tinsolder to be easier to wetting mutually.

Ethylene glycol and MALEIC ANHYDRIDE are after hyperthermic treatment, and combination reaction becomes the unsaturated polyester material, when the maintenance block moulding, as the crosslinked type wedding agent material of grasping, produce the solid shape of wishing acquisition.

For obtaining better effect: described organic dibasic acid content is the 0.01-40% of maintenance block weight percent.

Described aluminum oxide powder or carborundum powder are that particle diameter is less than 50 orders.Content is the 0.01-15% of maintenance block weight.

Described borax content is 0.01～15% of maintenance block weight.

Described ethylene glycol content is 0.01～4% of maintenance block weight.

Described MALEIC ANHYDRIDE content is 0.01～4% of maintenance block weight.

Compared with prior art, the invention has the advantages that:

By the rational proportion of each component, make it can clean and repair welding head, effectively prolong welding head work-ing life, save a large amount of copper resources.

Cleaning and very easy when repairing welding head, if with welding head at the simple reciprocating friction in maintenance block surface, so saving of work and time can be increased work efficiency.

The environmentally harmful material that RoHS instructions such as not leaded, the cadmium of employed component, mercury are limited in the whole composition, after therefore using, waste can natural degradation, and degradative phase is short, and most of composition can be by soil vegetative cover as dietetic alimentation, and is environmentally friendly, compliance with environmental protection requirements.
