Embodiment 1

[0032] Put 30 parts of polyisobutylene B5000 into a vacuum kneader, raise the temperature to 160°C, and stir for 0.8 hours under a vacuum condition of 0.09-0.094MPa; 1 part of resin, 2 parts of uniform tackifier, 3 parts of polyethylene wax and stir for 0.6 hours; then add 10 parts of EVA and 10 parts of butyl rubber and stir for 1.0 hour; finally add 5 parts of carbon black and stir for 0.5 hours; at 0.09~0.094 Stir under MPa vacuum condition for 0.5 hour and discharge after passing the inspection. Heat the rubber material to 110°C, press it to a thickness of 0.7mm on a coating machine, and then cut it into a tape with a width of 10mm on a cutting machine.

Embodiment 2

[0034] Put 50 parts of polyisobutylene B500 into a vacuum kneader, raise the temperature to 180°C, and stir for 1.5 hours under a vacuum condition of 0.09-0.094MPa; 5 parts of resin, 7 parts of uniform tackifier, 6 parts of polyethylene wax and stir for 1.5 hours; then add 20 parts of EVA and 20 parts of butyl rubber and stir for 1.5 hours; finally add 10 parts of carbon black and stir for 1 hour; Stir under 0.094MPa vacuum condition for 1.0 hour and discharge after passing the inspection. Heat the rubber material to 110°C, press it to a thickness of 0.7mm on a coating machine, and then cut it into a tape with a width of 10mm on a cutting machine.

Embodiment 3

[0036] Put 505 parts of polyisobutylene B5 into a vacuum kneader, raise the temperature to 170°C, and stir for 1.0 hour under the vacuum condition of 0.09-0.094MPa; 3 parts of resin, 5 parts of uniform tackifier, 4.5 parts of polyethylene wax and stir for 1.2 hours; then add 15 parts of EVA and 16 parts of butyl rubber and stir for 1.3 hours; finally add 8 parts of carbon black and stir for 0.8 hours; at 0.09~0.094 Stir under MPa vacuum condition for 0.7 hours and discharge after passing the inspection. Heat the rubber material to 110°C, press it to a thickness of 0.7mm on a coating machine, and then cut it into a tape with a width of 10mm on a cutting machine.

Abstract

The invention relates to a butyl hot melt adhesive tape and a preparation method thereof. The preparation method comprises the following steps: 1) adding polyisobutylene into a vacuum kneader, rising the temperature, and conducting a first stirring; then adding a plasticizer, an antioxidant, a modified phenolic resin, a carbon 5 resin, a homogenizing tackifier and a polyethylene wax, and conducting a second stirring to obtain a mixture A; 2) sequentially adding EVA and a butyl rubber into the mixture A obtained in the step 1), and conducting a third stirring to obtain a mixture B; 3) adding carbon black into the mixture B obtained in the step 2), and conducting a fourth mixing to obtain an adhesive material; and 4) heating the adhesive material obtained in the step 3), and then pressing and cutting to obtain the butyl hot melt adhesive tape.

Description

technical field [0001] The invention relates to a butyl hot-melt adhesive tape and a preparation method thereof, in particular to a butyl hot-melt adhesive tape used for edge sealing of solar double-glass components. Background technique [0002] As one of the main green energy sources, solar energy uses solar panels for photoelectric conversion. According to the "12th Five-Year Development Plan for Solar Photovoltaic Industry" issued by the Ministry of Industry and Information Technology, by 2015, the cost of photovoltaic modules will drop to 7,000 yuan / kW, and the cost of power generation will drop to 0.8 yuan / kWh. The solar photovoltaic industry The crystalline silicon module industry is facing huge cost pressures. Borderless double-glass modules are low in cost, strong in rigidity, and resistant to aging. They are currently the most advanced packaging method and development trend in the world. Solar borderless double-glass modules require extremely low water vapor trans...
