Description

The special-purpose fluorine silica gel plate of a kind of solar photovoltaic assembly vacuum laminator

Technical field

The utility model relates to solar cell manufacturing industry, particularly the special-purpose fluorine silica gel plate of a kind of vacuum laminator of solar photovoltaic assembly.

Background technology

Along with day by day highlighting of the problem of environment and resource, solar energy utilization has become the main flow strategy of countries in the world energy development.Greatly developed in recent years in the world the solar photovoltaic electric power of energy-saving and environmental protection type.Therefore, the manufacturing technology of solar cell, equipment and market are all developed rapidly in recent years.In recent years; the production of China's solar-energy photo-voltaic cell is with the speed increment of 30-50%; become big producing country; but be subject to global financial crisis and American-European on the two anti-impacts of China photovoltaic enterprise; how to reduce the production cost of solar cell, improve the first-selection that product competitiveness in the market becomes China photovoltaic enterprise.When producing solar photovoltaic battery component, laminating machine condition of work is 138 ℃-148 ℃ of temperature, vacuumizes in negative 0.1 atmospheric situation, adopt vinyl acetate (EVA) as binding material, single-chip or multi-silicon wafer glass and notacoria are pressed into battery component.The silica gel plate that laminating machine is used is critical component, has played the effect of sealing lamination.While melting bonding due to EVA heat, discharge a large amount of sour gas, during silica-gel board of laminator work, need vacuumize and exit, therefore the performances such as the temperature tolerance of silica gel plate, anti-corrosive properties, wearability, elongation shrinkage factor and smooth fineness being had to very high requirement.

The silica gel plate using on solar photovoltaic battery component laminator is at present generally silicane rubber plate or EP rubbers plate, the silicon special offset plate that comprises my company, lamination number of times is more than 5000 times, for better meeting the needs of the super wide cut silicon special of the desired high-performance of large-sized photovoltaic assembly forming equipment offset plate, my company has increased again a kind of fluorine silica gel plate on the basis of protosun energy photovoltaic module silica gel plate special for vacuum laminating machine, overcome existing silica gel plate and be subject to heat resistance, the UPS upper performance score systems such as tear resistance, provide, anti-corrosive properties, wearability, extend the performances such as shrinkage factor and smooth fineness, and lamination number of times can reach the special-purpose fluorine silica gel plate of a kind of solar photovoltaic assembly vacuum laminator of 6000 times, there is better heat resistance, tearing toughness is larger, can effectively meet large-sized photovoltaic assembly forming equipment requirement etc.To better meet the market demand.

Summary of the invention

The special-purpose fluorine silica gel plate of a kind of solar photovoltaic assembly vacuum laminator of the present utility model, is characterized in that: it draws blending layer of cloth (3) to form by fluororubber layer (1), silastic-layer (2), glass Kev.

Its manufacturing process is as follows:

First silicon rubber, hydrogenated nitrile-butadiene rubber are put into altogether to banbury by mixing, filtration, extruding, squeezed out silicon rubber film, then silicon rubber film draws blended cloth to be fitted in the centre of silicon rubber film glass Kev by cooling; And then fluorubber is put into the independent banburying of banbury, filtration, extruding, squeeze out fluorubber film, fluorubber film by cooling again with silica gel plate wherein one side carry out rubberizing and carry out drum-type sulfuration after bonding, fluororubber layer (1), silastic-layer (2), glass Kev draw the special-purpose fluorine silica gel plate of blending layer of cloth (3).

Described silicon rubber film be by silicon rubber, hydrogenated nitrile-butadiene rubber together the mixing mixer mixing of putting into altogether filter, the mode that adopts calendering to extrude is rolled the silicon rubber film even thickness of extruding, by cooling device, silica gel plate can be out of shape because of tension force in process of production.

Described fluorine silica gel film is fluorubber to be put into banbury refine separately, filter, the mode that adopts calendering to extrude is rolled the fluorine silica gel film even thickness of extruding, by cooling again with silica gel plate wherein one side carry out rubberizing bonding after, carry out again drum vulcanizer sulfuration, more than width reaches 4000mm, and product length can endless, avoids occurring impression, the surface thickness non-uniform phenomenon between plate and plate on flat board.

Described adds other auxiliary materials for two 25 anti-yellowing change vulcanizing agents, high-reinforcement white carbon black, FN309 glue, TOP auxiliary agent in the bonding segmentation of which floor rubberizing.

The special-purpose fluorine silica gel plate of a kind of solar photovoltaic assembly vacuum laminator of the present utility model, there is the performances such as heat resistance, tearing toughness, anti-corrosive properties, wearability, elongation shrinkage factor and smooth fineness, and lamination number of times can reach 6000 times, can effectively meet large-sized photovoltaic assembly forming equipment requirement etc.

The invention has the beneficial effects as follows: the special-purpose fluorine silica gel plate of solar photovoltaic assembly vacuum laminator of the present invention adopts fluorubber, three kinds of active principles of silicon rubber and hydrogenated nitrile-butadiene rubber, wherein silicon rubber and hydrogenated nitrile-butadiene rubber fully mix, merge, and add suitable rubber processing aids its performance is carried out to reasonable modification, in the one side of its silica gel plate contact battery, roll again and paste one deck fluorubber, it is met and meet the higher production requirement of solar photovoltaic assembly vacuum laminator, the rugged environment condition of complete energy adaptation layer press when lamination is manufactured solar photovoltaic assembly, i.e. 138 ℃ of-148 ℃ of high temperature, the acid etchant gas of EVA, vacuumize negative 0.1 atmospheric pressure and the repeated multiple times harmomegathus process that circumnutates.There is the performances such as better temperature tolerance, tear resistance, anti-corrosive properties, wearability, elongation shrinkage factor and smooth fineness, and intensity is high, lamination number of times is higher, fabric width is large, can effectively meets large-sized photovoltaic assembly forming equipment requirement etc.
