[0035]

[0036]

[0037] Table 2

[0038]

[0039] The above-mentioned conductive adhesive for anti-aging solar shingled components is prepared by the following method:

[0040] (1) First, add the acrylate prepolymer, acrylate monomer, anti-aging additives and adhesive additives into the double planetary mixer, and stir for 30 minutes to 60 minutes to mix the above materials evenly.

[0041] (2) Then add the conductive filler into the double planetary mixer and mix for 30min-60min.

[0042] (3) The double planetary mixer reaction kettle jacket is connected with cooling water, fully cooled, so that the material in the reaction kettle is cooled to within 20 °C.

[0043] (4) Add the initiator, and stir gently under cooling conditions to make the ini...

Abstract

The invention discloses a conductive adhesive for an anti-aging solar imbricated component and a preparation method of the conductive adhesive, and solves the problems that an existing conductive adhesive technique is poor in heat and moisture aging resistance, and contact resistance remarkably raises along with aging time at the temperature of 85 DEG C under the aging condition of 85%. The conductive adhesive comprises, in weight, 15%-25% of acrylate prepolymers, 10%-30% of acrylate monomers, 1%-5% of anti-aging agents, 1%-5% of bonding agents, 0.3%-1.5% of initiators and 40%-65% of conductive fillers. The conductive adhesive has excellent ageing resistance and is high in bonding strength and quite remarkable in effect, and volume resistance and contact resistance are low.

Description

technical field [0001] The invention relates to a conductive adhesive composition, in particular to a conductive adhesive for anti-aging solar shingled components and a preparation method thereof. Background technique [0002] Shingled solar cell modules exhibit higher photoelectric conversion efficiency than conventional modules. Shingled components use conductive adhesives to bond battery sheets, which need to be used in the working environment for a long time, with a lifespan of up to 25 years. The conductive adhesive is required to have excellent anti-aging properties. [0003] Although compared with Pb~Sn solder, the conductive adhesive has the advantages of high line resolution, does not contain Pb or other toxic metals, can be connected at low temperature, has good flexibility and fatigue resistance, and the conductive adhesive also has anti-aging properties. Poor problems, specifically, the contact resistance of conductive adhesive joints increases rapidly over time...
