Embodiment 1

[0012] 1. Preparation of YVO 4 :Eu 3+ ,Sr 2+ Nano phosphor

[0013] (1) Add 1.2mmolNa 3 VO 4 12H 2 O was dissolved in a mixed solution containing 5ml ethylene glycol and 2ml distilled water; (2) The above solution was ultrasonically stirred (80KHz ultrasonic vibration and 300r / min centrifugal speed stirring) and added dropwise with a certain proportion of 1.5mmol Y ( NO 3 ) 3 ·6H 2 O,Eu(NO 3 ) 3 ,Sr(NO 3 ) 2 (0.9:0.03:0.07) in 8ml of ethylene glycol solution, then ultrasonically stirred (80KHz ultrasonic vibration and 300r / min centrifugal speed stirring) for 10min until the solution was clear, then added 20ml of distilled water; (3) Pour the reaction solution into a volume of 50ml In a polytetrafluoroethylene-lined autoclave, in a vacuum environment, 200 o C under heat preservation reaction 1h, down to 150 o C under insulation reaction 1h, after the end of the reaction, cooled to room temperature. The resulting suspension was poured out, centrifuged and washed 3...

Abstract

The invention discloses an EVA master batch used for an EVA glue film. The EVA master batch is prepared from the following materials in parts by weight: 30 to 50 parts of ethylene-vinyl acetate copolymer, 5 to 10 parts of ethylene-octene copolymer, 1 to 5 parts of polyethylene, 0.1 to 1 part of an initiator, 0.5 to 1.5 parts of a tackifier and 5.05 to 9 parts of a red light and fluorescent light composition, wherein the red light and fluorescent light composition is a red light and fluorescent light composition of YVO4:Eu<3+>, Sr<2+>@YVO4:Eu<3+>, Bi<3+> or YVO4:Eu<3+>, Sr<2+>@YVO4:Eu<3+>, Bi<3+>@Ag@SiO2. According to the EVA master batch used for the EVA glue film, the defect that in a production process of a common solar photovoltaic assembly EVA glue film, an additive is not easy to disperse uniformly, and the quality of the EVA glue film is improved; the included red light and fluorescent light composition is better in dispersity and higher in light conversion efficiency and light intensity, and further improves the applicability of the EVA master batch.

Description

technical field [0001] The invention relates to an EVA master batch for EVA film. Background technique [0002] EVA refers to ethylene-vinyl acetate resin, which is a plastic resin that can be used as hot melt adhesive. It is widely used in the fields of laminated glass, solar photovoltaic module packaging, metal plate and plastic plate bonding, especially in solar photovoltaic The field of application is very wide. The main suppliers of EVA film in China include Foster, Haiyouwei, Yonggu and so on. EVA adhesive film is a thermosetting and sticky adhesive film in the field of solar photovoltaics. It is used in photovoltaic modules in the form of glass / EVA adhesive film / photovoltaic cell / EVA adhesive film / back sheet, which plays a role in packaging and protecting cells. It is one of the most important components in the assembly. [0003] In the prior art, the dispersion of additives in the production process of commonly used solar photovoltaic module EVA film is easy to be...
