Description

A kind of special scaling powder of solar energy automatic welding

Technical field

The invention belongs to welding technology field, be specifically related to a kind of special scaling powder of solar energy automatic welding.

Background technology

Photovoltaic generation is a kind of photovoltaic effect utilizing solar cell semi-conducting material, can directly be changed by solar radiation A kind of new power generating system for electric energy.Solar energy be clean most future, the safe and reliable energy, developed country is too The exploitation of sun energy are as energy revolution main contents Long-term planning, and photovoltaic industry is increasingly becoming the IT that continues in the world, micro-electricity The industry of another explosive growth after sub-industry.Industrial advantage: 1, never exhausted.2, needed for setting up solar power plant Time and cost are all low than power station.3, exploit and use solar energy not result in environmental pollution, being preferable green energy resource. Cell piece and photovoltaic welding belt weld as a ring important in solar module manufacture process, and its processing effect is to solar energy The performance of battery component plays important impact.At present, the most also there is no the patent of the special scaling powder of corresponding welding, domestic Producer mostly uses the scaling powder of import, due to price reasons, considerably increases manufacturing cost.Meet the scaling powder of automatic welding Need to reach following performance:

(1) solids content is low, noresidue after welding;

(2) good weldability, changes stannum smooth, and after welding, welding and cell piece bond strength are high;

(3) stannum face is uniform, light, bad without paving stannum, tin sweat(ing), rosin joint etc.;

(4) assembly after welding can be by double 85 or double 95 burn-in tests;

(5) after component lamination welding without white macula and yellowing phenomenon.

Summary of the invention

It is an object of the invention to provide a kind of be applicable to the low-solid content of solar components automatic welding, low-residual, The scaling powder that adhesion is good.

The present invention is achieved like this.A kind of special scaling powder of solar energy automatic welding, it is by following weight percentage ratio Raw material make: modified resin 0.1~0.2%, combine organic acid 1.6~2.0%, fluorocarbon surfactant 0.1~0.2%, Surplus is alcohols solvent.

Described modified resin uses modified rosin resin, and the active ingredient of other in scaling powder is adsorbed onto by Main Function Substrate surface, the effect of playing stannum under automatic equipment hot conditions, can effective raising stannum speed.

Described combination organic acid can be two kinds in succinic acid, 1,3-propanedicarboxylic acid, adipic acid, citric acid, oxalic acid or above group Compound.Main Function is the oxide cleaning substrate surface, plays the effect of activated substrate, the welding of 320-350 degree Celsius Can decompose completely without any residual in temperature range.

Described fluorocarbon surfactant uses perfluor class surfactant, has good dispersibility, levelability, effectively drops Low substrate surface tension.

Described alcohols solvent can be dehydrated alcohol or isopropanol, has abnormal smells from the patient little, the feature that rate of volatilization is moderate.

The present invention has stannum face flat smooth, and adhesion is high, and rosin joint rate is low, without the advantage of white macula jaundice after lamination, simultaneously Meet photovoltaic industry double 85 and double 95 age testing requirements.It is applicable to solar battery sheet welding automatic welding, soldering reliability Height, rosin joint rate is low.

Detailed description of the invention

In order to make it easy to understand, the present invention is further elucidated with below in conjunction with embodiment.
