Example Embodiment

[0027] Example 1:

[0028] The adhesive applied on the front surface of the tape substrate is mainly used for bonding. In parts by weight, the components and content of the adhesive are:

[0029] Ammonium Sulfate (APS)

[0030] Tackifying resin

[0031] First, prepare the adhesive in a reactor equipped with a condenser, a mechanical stirrer, a dropping funnel, nitrogen inlet and outlet, and a thermometer. Adopt pre-emulsification process, pass in nitrogen protection, weigh according to the above formula components: HAM, BA, MMA, AA, HEA, AMPS, SDS, OP-10 and 300ml deionized water into the reactor, stir to pre-emulsify 1 hour. Then take 200ml of pre-emulsion, add sodium bicarbonate to adjust the pH to about 5, add 10ml initiator APS (20%) solution, add it to the reactor, continue to pass nitrogen protection, control the temperature at 85 ℃, turn on the stirrer, and control the speed At 400r / min. When the material in the reactor gradually turned into a blue seed emulsion, th...

Abstract

The invention relates to a double-sided adhesive tape, and specifically relates to the double-sided adhesive tape used for a solar cell assembly and a preparation method thereof. The double-sided adhesive tape comprises a substrate, an adhesive, a backlining and backlining glue, wherein the adhesive mainly comprises the following components of, by weight, 0.5-1 part of ammonium sulfate, 5-10 parts of methyl methacrylate, 55-65 parts of butyl acrylate, 20-30 parts of hydroxymethyl acrylamide, 1-2 parts of a composite emulsifier, 60-70 parts of a tackifying resin, 0.2-0.8 part of acrylic acid, 1-2 parts of hydroethyl methacrylate, 1-1.5 parts of 2-acrylamide-2-methylpro panesulfonic acid and 1-3 parts of 3-(methacryloxy)propyltrimethoxysilane. The preparation method comprises the steps of firstly pre-preparing a high-strength organosilicone and acrylate co-polymeric emulsion pressure-sensitive adhesive; and then performing operations of double roll reverse coating, drying, compositing, transferring and the like with a B-50 multifunctional coating machine, wherein both the font side and the back side of the backlining of the substrate are already coated by a layer of low-adhesivity backlining glue.

Description

technical field [0001] The invention relates to a double-sided adhesive tape, in particular to a double-sided adhesive tape used for packaging solar cell modules and a manufacturing method thereof. Background technique [0002] Solar photovoltaic power is currently the most economical, cleanest and most environmentally friendly sustainable energy available. Solar cells are the core components of solar photovoltaic systems. Due to physical and chemical defects such as thinness, brittleness and easy oxidation of solar cells, long-term exposure to high humidity, high temperature, low temperature, strong ultraviolet rays, ozone, microorganisms, wind and rain and other natural conditions can easily cause water permanent damage, and it is difficult to application. Therefore, in order to realize the industrialized application of solar power generation, especially to achieve a service life of more than 20 years, protective packaging is required to form a solar cell module with sta...
