Description
Technical field
The present invention relates to high molecular polymer Technology field, especially relate to a kind of auxiliary agent for the preparation of photovoltaic grade polyvinyl butyral acetal.
Background technology
Polyvinyl butyral acetal (PVB) material that wear-resisting safety coefficient is high, soundproof effect is good, after being widely used in automobile and construction industry, opens new application space in solar photovoltaic cell panel field again in recent years.The sustainable growth of PVB materials demand amount, has huge market potential.
PVB materials application, in photovoltaic battery panel, as sealing material, can extend the work-ing life of cell panel, make photovoltaic cell high temperature and comparatively under intensive ultraviolet radiation retention stablize.Common PVB material molten index is lower, well can not adapt to the cell piece in glass light photovoltaic assembly.
In prior art, usually by increasing the method for softening agent on the basis of common PVB material prescription, improving the melting index of PVB material, obtaining photovoltaic grade PVB material.Common PVB material prescription comprises polyvinyl butyral resin, softening agent, oxidation inhibitor.Selectable softening agent comprises triglycol two 2-ethylhexoate; Selectable oxidation inhibitor comprises SONOX-1076 or SONOX-1010.There is following defect in the preparation method of above-mentioned photovoltaic grade PVB material: in the actual course of processing, and the softening agent added in common PVB material is easily separated out, and causes producing bubble in product, thus causes product defective.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of easy to use, and the processing aid of effect stability improves the quality product of photovoltaic grade polyvinyl butyral acetal.
For solving the problems of the technologies described above, present invention employs following technical proposal:
A processing aid for photovoltaic grade polyvinyl butyral acetal, is made up of chromic acid metal-salt.
Improvement of the present invention is: described chromic acid metal-salt is chromic acid an alkali metal salt or chromic acid alkaline earth salt.
Further improvement of the present invention is: described chromic acid an alkali metal salt is one or both the mixture in Sodium chromate, potassiumchromate.
Another kind of the present invention improves and is: described chromic acid alkaline earth salt is magnesium chromate.
The preparation method of the photovoltaic grade polyvinyl butyral acetal of auxiliary agent of the present invention is adopted to be: to be dispersed in water by described processing aid, be mixed with the mixture that mass percentage is 1 ~ 5%, after this mixture is mixed with polyvinyl butyral resin, softening agent, oxidation inhibitor, by melting, extrude, cooling process, obtain photovoltaic grade polyvinyl butyral acetal, wherein, in mass fraction
Processing aid 0.1 ~ 0.45 part;
Polyvinyl butyral resin 71.5 ~ 73.5 parts;
26.5 ~ 28.5 parts, softening agent;
0.05 ~ 0.1 part, oxidation inhibitor.
Preparation method of the present invention is improved to: described softening agent is triglycol two 2-ethylhexoate, and described oxidation inhibitor is commercially available SONOX-1076 or SONOX-1010.
Compared with prior art, the invention has the advantages that:
The present invention adopts chromic acid metal-salt as the processing aid of photovoltaic grade polyvinyl butyral acetal, easy to use, after adding this auxiliary agent, the precipitation of softening agent in the course of processing can be avoided to produce the problems such as bubble, improve the qualification rate of photovoltaic grade PVB product processing, reduce production cost, there is good economic benefit and promotion prospect.
Sodium chromate, potassiumchromate, magnesium chromate have good solubility, and being configured to mass percentage is after the solution of 1 ~ 5%, can play satisfactory stability effect, effectively can avoid the precipitation of softening agent.Polyvinyl butyral resin and softening agent is mainly comprised in the component of photovoltaic grade polyvinyl butyral product of the present invention, polyvinyl butyral resin is slightly acidic, in the course of processing, along with temperature raises and time lapse, namely easy volatilization separates out, and causes product defective.When adopting acidic plasticiser triglycol two 2-ethylhexoate, above-mentioned precipitation effect can be more obvious.Chromic acid basic metal or alkaline-earth metal salt, have natural weak alkali, as processing aid, can in and the sour environment of material, thus phenomenon of volatilizing can be avoided.Experimental studies have found that through a large amount of, magnesium chromate, Sodium chromate, potassiumchromate and composition thereof, for the processing of photovoltaic grade polyvinyl butyral acetal, have best stabilising effect.
Embodiment
Specific embodiment described is herein only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Embodiment 1 ~ 5
Prepare photovoltaic grade polyvinyl butyral acetal by the following method.
Take a certain amount of chromic acid metal-salt, after mixing, be dispersed in water, be mixed with the mixture that mass percentage is 1 ~ 5%, after being mixed with polyvinyl butyral resin, softening agent, oxidation inhibitor by this mixture, by charging system, send into forcing machine, successively by net-changing device, toothed gear pump, extrude from die head, enter tank cooling and shaping, then through the inspection of aftertreatment and thickness measurement device, qualified product is after reeling machine arranges, and packaging is put in storage.In said process, between described die head to thickness measurement device, the conveying of material provides power by traction system; Described thickness measurement device connects thickness control system, to the material of disqualified upon inspection, reclaims.Wherein, material polyethylene polyvinyl butyral resin, calculate by polyvinyl alcohol, hydroxy radical content is 18.0% ~ 21.0%.
Described softening agent is triglycol two 2-ethylhexoate.Described oxidation inhibitor is commercially available SONOX-1076 or SONOX-1010.Measure the melting index of gained photovoltaic grade polyvinyl butyral acetal, and record the precipitation situation of softening agent in preparation process.The kind of measurement result and each raw material, consumption are in table 1.
Table 1
From table 1 experimental result, after adding auxiliary agent of the present invention, in the course of processing of photovoltaic grade polyvinyl butyral, while improving melting index, effectively can avoid the precipitation of softening agent, improve quality and the qualification rate of product, have a good application prospect and promotional value.
