Abstract
The invention discloses a high-watertightness solar module edge-sealing adhesive tape, comprising a base material layer, a functional adhesive layer and a release material layer arranged in succession from top to bottom.The functional adhesive layer is formed by: dissolving rubber adhesive in an organic solvent to form a solution and applying the solution to the release material layer; the adhesive tape is characterized in that the rubber adhesive is made from the following components according to parts by weight: 80-120 parts of a main agent and 20-30 parts of a viscosifier, wherein the main agent at least comprises butyl rubber.Since the rubber adhesive in the middle functional adhesive layer uses the butyl rubber of high watertightness as the main agent, watertightness of the whole adhesive tape is greatly enhanced; in the adhesive tape compared with original acrylic foam adhesive, the adhesive layer formed by curing of butyl rubber is better in softness and application performance, and thereby, this adhesive layer is imparted same bonding force through only half of usage of original acrylic foam adhesive, helping reduce overall thickness of the adhesive tape.
Description
Technical field
The invention belongs to PSA technology field, be specifically related to a kind of high water resistance solar components edge sealing adhesive tape.
Background technology
Current solar components, for instance be designed with special edge sealing adhesive in all kinds of photovoltaic cell goods and bring reinforcement by connection glass edge.This kind of adhesive tape is all formed by multiple structure lamination, upper strata is substrate layer, lower floor is separated type material layer, acrylic foamed glue is used in centre, has the effect of the water that blocks water, but block-water effect is inconspicuous, and expanded material is thicker also harder, pasting property is bad, yielding after aging, and corner is easily protruding because of overlapping.
Summary of the invention
The problem to be solved in the present invention is: provide the better effects if of a kind of water that blocks water, flexibility and applicating property high water resistance solar components edge sealing adhesive tape more preferably.
For solving the problems referred to above, present invention provide the technical scheme that a kind of high water resistance solar components edge sealing adhesive tape, including the substrate layer set gradually from top to bottom, function glue-line and separated type material layer, described function glue-line be dissolved in organic solvent being formed rubber-like adhesive coat after solution separated type material layer solidifies after formed, it is characterized in that the composition of described rubber-like adhesive comprises by the following component of mass parts: host 80～120 parts and viscosifier 20～30 parts, wherein said host includes at least butyl rubber.
It is further preferred that heretofore described host is 100 parts, and viscosifier are 25 parts.
It is preferred that, heretofore described host also comprises rubber adjuvant, this rubber adjuvant be one or several in ethylene propylene diene rubber, buttress rubber, neoprene by the mixture of any mass ratio, and in described host, the mass percent of butyl rubber is 70～80%, and the mass percent of rubber adjuvant is 20～30%.
Further preferred, in heretofore described host, the mass percent of butyl rubber is 75%, and the mass percent of rubber adjuvant is 25%.
It is further preferred that heretofore described viscosifier are the mixture of one or more in Colophonium esters viscosifier (such as GB-100, GB-75), terpene phenol class viscosifier (such as T-803L) and Petropols class viscosifier (such as FTR6100).
It is further preferred that the thickness of heretofore described function glue-line is 50～100 μm.
The present invention does not do special restriction for the organic solvent of dissolving rubber class adhesive, for instance optional toluene, dimethylbenzene, dehydrated alcohol or ether etc..
The saturating rate WVTR < 8g/m of water of heretofore described function glue-line2.day, the saturating rate of water is more little shows that block-water performance and water seal characteristic are more good.
Heretofore described substrate layer can select the fluorine film of routine, PVC, PET film or various plastic alloy film, certainly the buffer insulation PVC film of preferred 100～400um thickness.
Heretofore described separated type material layer is conventional mould release membrance or release paper.
The invention have the advantage that
This adhesive tape provided by the invention is owing to the function glue line material in the middle of it is with the reasonable butyl rubber of block-water performance for host, therefore greatly strengthen the block-water performance that adhesive tape is overall, compare original acrylic foamed glue simultaneously, flexibility and the applicating property of the glue-line that butyl rubber is formed after solidifying are better, therefore this kind of glue-line reaches same adhesion strength and only needs the consumption of acrylic foamed glue half originally, contributes to the reduction of adhesive tape integral thickness.
2. the intermediate function glue-line of adhesive tape of the present invention is with butyl rubber for host, and resistance to ag(e)ing is better, and edge sealing uses not easily aging deformation after attaching, it is possible to the situation of projection occurs because of overlap to prevent solar components goods corner.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further, but is not limited to these embodiments.
Embodiment, this high water resistance solar components edge sealing adhesive tape provided by the invention is as the prior art, it is made up of the substrate layer (buffer insulation PVC film), function glue-line and the separated type material layer (mould release membrance) that set gradually from top to bottom, the present invention is mainly improved by function glue-line, function glue-line in this example be dissolved in toluene being formed rubber-like adhesive coat after solution separated type material layer solidifies after formed, each embodiment below gives the formula (mass parts meter) of rubber-like adhesive:
Embodiment 1. butyl rubber 100 parts, tackifying resin T-803L25 part, add toluene and be dissolved into solution, on coating mould release membrance, dry glue thickness is 50 μm, is transferred in the PVC base (buffer insulation PVC film) that thickness is 100 μm after drying, prepares adhesive tape product.
Embodiment 2. butyl rubber 75 parts, ethylene propylene diene rubber EPDM25 part, tackifying resin FTR610025 part, add toluene and be dissolved into solution, on coating mould release membrance, dry glue thickness is 50 μm, is transferred in the PVC base (buffer insulation PVC film) that thickness is 100 μm after drying, prepares adhesive tape product.
