Description
[technical field]
The invention belongs to environmental technology field and solar cell package technical field of material, be specifically related to one novel too
Sun can cell package environment-friendly materials.
[background technology]
In the face of affecting the energy shortage of the people's livelihood and economic development, the fossil energy that we rely on for a long time more can be following one or two hundred
Exhausting between Nian, people are just striving to find low-carbon (LC) or the new forms of energy of zero carbon and production technology, in numerous new forms of energy approach, and solar energy
Due to nexhaustible, and it is contemplated that following five become mankind's main energy sources during the decade.At the global sun in 2010
The installation total amount that can generate electricity is about 18GW, and China's solaode total growth in the same year is about 10GW, both increases very fast
Long;Solar cell package technology becomes one of key technology of this new industry of solar energy development.
In current industry, the packaging process in conventional solaode light front has following multinomial step: (a) produces
The encapsulating film of polyethylene-vinylacetate (EVA) thermo-bonded materials or relevant encapsulating film；B () is according to the chi of solar panel
Very little cut out EVA encapsulating film；C () forms the sandwich of battery-encapsulating film-glass plate；(d) hot adhesion.
When encapsulating battery bottom surface, process is more: (a) produces polyethylene-vinylacetate (EVA) thermo-bonded materials
Encapsulating film or relevant encapsulating film: (b) cuts out EVA encapsulating film according to the size of solar panel: (c) covers battery floor
Face: (d) produces the diaphragm seal of multilamellar and (generally include such as politef/polyethylene terephthalate/polytetrafluoroethyl-ne
Alkene, is called for short the film material of TPT: (e) adds a cover TPT diaphragm seal on the encapsulating film that EVA is hot sticky: (f) hot adhesion.
Plastic used in this packaging process is all from petrochemical industry route, the most not green product, and
Thermal bonding be power consumption, time-consuming.On the one hand another bigger problem is that we go to overcome the fossil energy will with solaode
The energy problem exhausted, on the other hand when encapsulating solaode and becoming energy instrument, we still rely on main material is stone
The chemical plastic of oil base and the operation of power consumption, this contradiction is urgently to be resolved hurrily.
Over more than thousand year, China uses Oleum Verniciae fordii coating protection furniture and ship and building structure for a long time, because Oleum Verniciae fordii coating is permissible
Being caused crosslinking curing by oxygen, viscosity is strong, waterproof, wear-resisting durable.And China's weather grows with the suitable tung oil tree of other natural environment,
Therefore Yao Ling other countries in terms of Oleum Verniciae fordii production always of China.But for a long time, Oleum Verniciae fordii industry continues to use traditional handicraft, utilize
High-tech is Oleum Verniciae fordii industry innovation simply ground zero；Multinomial patent disclosure utilizes the method that Oleum Verniciae fordii does coating and resin raw material
(application number 200810031013.X；201110093579.7；201110002171.4；200410065369.7；
200910185732.1；200910070756.2；200910218768.5 etc.)；In Application No. 201110076740.X
State's patent describes the method utilizing tung oil acid anhydride to prepare full biobased epoxy resin composition and solidfied material；It is contemplated that pass through
New Oleum Verniciae fordii technology and application are developed in system scientific research and innovation, and Oleum Verniciae fordii will become the important sources of solar cell package material.
Solar module is that the photovoltaic effect utilizing the quasiconductors such as silicon is directly converted into electricity sunlight by P-N junction
Can product, the mode such as solaode the most all must be sealed by glue, lamination is packaged into flat structure and comes into operation, limit
The silicone sealant that sealing of frame uses weatherability and aging resistance, adhesive property is good.At present, conventional silicone sealant is all single
Component, its curing rate is slow, and the time is long, and in solar components production process easily " overflow glue ", has a strong impact on production
Efficiency.The Chinese patent of Application No. 201010191169.1 discloses and a kind of assembles the double of glue envelope for solar module
Component solar sealant and preparation method thereof.It is made up of component A and B component two parts；Wherein component A: base polymer 0-
100 parts, plasticizer 10-50 part, filler 50-100 part, reinforcing agent 1-10 part；B component: end alkoxy polysiloxane 0-100 part,
Dimethicone 0-100 part, pigment 5-30 part, cross-linking agent 50-100 part, coupling agent 5-30 part, catalyst 0.001-5 part.Its tool
There is curing rate fast, stable storing, do not produce the feature of " overflow glue ".Although the bi-component sun disclosed above
Can have certain functional characteristics by fluid sealant, but be as the development of heliotechnics, the feature of itself can not
Meeting the needs of development, its curing rate, stability, resistance to ag(e)ing and gluing intensity etc. all can not meet growing need
Want, therefore also need to research and develop a kind of fluid sealant with more excellent properties further.
[summary of the invention]
The present invention provides a kind of novel solar battery encapsulation environment-friendly materials, to solve the solidification of existing solar cell package material
Speed is slow, and stability, resistance to ag(e)ing are poor, and gluing intensity is low, and toxicity is big, easily causes the problems such as environmental pollution.The present invention is by Oleum Verniciae fordii
Sill replaces petroleum base polymeric material for the encapsulation of solaode, wide material sources, prepares easy, easy to operate, produces
Product excellent performance, environmental friendliness, reduce petroleum resources and the consumption of the energy, green energy conservation in solar cell package, have
It is widely applied prospect, is the green encapsulating materials of a kind of innovation.
