Description
Technical field
The present invention relates to building scaling powder technical fields, and in particular to a kind of halogen-free scaling powder and preparation method thereof.
Background technique
Scaling powder：Welding process can be helped and promoted in welding procedure, while there is protective effect, prevent oxidation reaction
Chemical substance.Scaling powder can be divided into solid, liquids and gases.Mainly there is " auxiliary heat transfer ", " removal oxide ", " reduce
Soldered material surface tension ", " remove and be soldered material surface and oil contaminant, increase bonding area ", " preventing from reoxidizing " etc. are several
Aspect, in terms of these in more crucial effect there are two be exactly：" removal oxide " and " the soldered material surface of reduction
Tension ".
In recent decades, electronic product produce soldering process during, generally mostly using mainly by rosin, resin, contain
Although this kind of scaling powder solderability of rosin resin system scaling powder of the activating agent of halide, additive and organic solvent composition is good,
It is at low cost, but the high of postwelding residue its residue contains halide ion, can gradually cause electrical insulation properties decline and short circuit etc.
Problem will solve the problems, such as this, it is necessary to carry out cleaning so not to the rosin resin system film of flux residue in electronics printed board
But it will increase production cost, and the cleaning agent for cleaning rosin resin system welding assisted agent residuals is mainly fluorine chlorine compound thisization
Close the loss substance that object is atmospheric ozone layer, the column for belonging to disabling and being eliminated.The technique for still having many companies to continue to use is to belong to
Aforementioned referred to using rosin tree is technique that scaling powder scolding tin is cleaned with cleaning agent again, and efficiency is lower and high expensive.
The quality of currently marketed scaling powder is still to be improved, for example currently marketed scaling powder has removal oxide
The disadvantage of property poor, corrosion resistance and solderability difference, the use scope of this currently marketed scaling powder also made compare limitation.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of anti-corrosion waterproof scaling powders, not only have except oxide,
Corrosion resistance and solderability it is good the advantages that.
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of halogen-free scaling powder, ingredient is by weight：25-42 parts of rosin resin, 12-18 parts of rosin amine, silicate

Preferably, a kind of halogen-free scaling powder, preparation method includes the following steps：
A, rosin resin, rosin amine and silicate resin are placed in pulverizer and are crushed, then ground by grinder
Mill, gained mixed component powder saves, spare；
B, the resulting mixed component of step a is added in organic solvent, is warming up to 85-110 DEG C and stirs 20-30min,
Obtained component is denoted as mixed component A；
C, gained mixed component A in step b is placed in high-speed stirred kettle, rises to 135-180 DEG C to temperature, it is then organic
Acid activators, sodium salicylate, acetamide and sodium benzoate are placed in high-speed stirred kettle, are stirred 35-48min, are obtained mixed solution；
D, the mixed solution in step c is placed in reaction kettle, then remaining material is placed in reaction kettle, is warming up to
165-190 DEG C, 24-32min is stirred for the revolving speed of 360-450r/min with mixing speed, then place the product in the fast quickly coolings of vacuum
But it is rapidly cooled in machine to get finished product.
Preferably, the organic acid for activating agent select succinic acid, glutaric acid, itaconic acid, septichen, sebacic acid and
Three kinds or four kinds therein of pimelic acid.
Preferably, the antioxidant selection primary antioxidant and auxiliary antioxidant, the primary antioxidant selection antioxidant 264,
Wherein two kinds or three kinds of antioxidant 1076, antioxidant CA and antioxidant 330, the auxiliary antioxidant rotation vulcanization dipropionic acid two
Month silicate and the double octadecyl ester pentaerythritol esters of two phosphorous salt.
Preferably, the anticorrosive select Quadrafos, chromate, oxidized paraffin wax, alkenyl succinic acid, aphthenic acids and
