preparation example Construction

[0015] The embodiment of the present invention provides a fast-curing solar cell module backplane composite adhesive and a preparation method thereof. The prepared composite adhesive has the characteristics of fast curing speed, high heat resistance, high humidity resistance and ultraviolet light resistance. The method includes the following steps:

[0016] Main ingredient preparation:

[0017] Put triethylene glycol, hydroxypivalic acid neopentyl glycol monoester, and 1,4-cyclohexanedimethanol into the esterification reaction kettle, fill with nitrogen protection, heat, dissolve and mix, and then put in terephthalic acid and phthalic anhydride , 1,12-lauric acid, gradually warming up the esterification reactor to 220°C, and the esterification reaction will start when the water is distilled from the esterification reactor. If the water output of the esterification reaction reaches the theoretical water output, the esterification reaction will be completed; The hydroxyl value a...

Embodiment 1

[0023] Prepare the main ingredient:

[0024] Put 11 kg of triethylene glycol, 19 kg of hydroxypivalate neopentyl glycol monoester, and 20.5 kg of 1,4-cyclohexanedimethanol into the esterification reaction kettle, fill with nitrogen protection, heat to 120°C to dissolve and mix , and then put in 12 kilograms of terephthalic acid, 19 kilograms of phthalic anhydride, and 18.5 kilograms of 1,12-lauric acid to gradually raise the temperature of the esterification reactor to 220 ° C. When the esterification reactor distills water, the esterification reaction begins. When the water output reaches the theoretical water output, the esterification reaction is completed; the hydroxyl value of the product measured by sampling is 13.2 mgKOH / g, and the acid value is 19.5 mgKOH / g. Add 20 grams of tetraisopropyl titanate catalyst to maintain the temperature of the esterification reaction kettle Vacuum at 220-230°C for polycondensation reaction, keep at -0.06Mpa vacuum for 1 hour; then evacuat...

Abstract

The invention provides a rapid-solidifying composite cementing compound of a solar component back plate and a preparation method thereof, and refers to the field of preparation of polyurethane cementing compound. The rapid-solidifying composite cementing compound is formed by mixing main agent and solidifying agent according to the mass ratio of (10-16): 1, wherein the main agent is prepared by the following raw materials in mass percent: 8-15% of triethylene glycol, 15-25% of hydroxypivalyl hydroxypivalate, 10-23% of 1, 4-cyclohexanedimethanol, 10-20% of terephthalic acid, 10-20% of phthalic anhydride, 15-25% of 1, 12-dodecanedioic acid, 10-60 ppm of organic tin catalyst, 20-100 ppm of organic amine accelerant and 0.5-4 % of carbodiimide hydrolysis-resisting stabilizer; the solidifying agent is at least one of HDI tripolymer, IPDI tripolymer and hydrogenated MDI tripolymer. According to the rapid-solidifying composite cementing compound of the solar component back plate and the preparation method, the prepared composite cementing compound is quick in solidyfing speed, and able to resist high temperature, high humidity and ultraviolet light.

Description

technical field [0001] The invention relates to the field of polyurethane adhesive preparation, is suitable for the recycling of alkylation waste acid, and in particular relates to a fast-curing composite adhesive for solar module back plates and a preparation method thereof. Background technique [0002] With the deepening of people's understanding of the seriousness of air pollution, the voice of replacing traditional high-pollution energy sources such as coal and oil is getting higher and higher. In recent years, clean energy represented by solar energy has emerged in large numbers and has become an important alternative to curb air pollution. One of energy. Solar modules are mainly composed of tempered glass, EVA film, silicon cells and composite backsheet. The back sheet is located on the back of the solar cell module and protects the cells. It must have reliable insulation, sealing, water resistance and aging resistance. Solar module backsheets generally have a three...
