Problems solved by technology

[0007] The disadvantage of γ-methacryloxypropyl trimethoxysilane is that: γ-methacryloxypropyl trimethoxysilane is easily hydrolyzed with water and forms insoluble polysiloxane after curing. And the degree of polymerization is generally a bit large, it is difficult to effectively apply in production and life
When γ-methacryloxypropyl trimethoxysilane is used to bond glass and EVA packaging film, KH-570 will be hydrolyzed and polycondensed into silanol and methanol. When the amount of KH-570 monomer is large, the methanol produced will be Bubbles will be generated on the EVA film, which will affect the service life of solar panels and greatly reduce the efficiency of converting light energy into electrical energy
In addition, the shelf life of the coupling agent is too short, and hydrolysis and polymerization will occur after about half a year of storage, and it is slightly irritating to the skin and eyes

Abstract

The invention discloses a coupling agent oligomer for enhancing adhesive property, and a preparation method thereof. The preparation method comprises the following steps: S1, adding a first solvent, a polymerization inhibitor, a catalyst and gamma-methacryloxypropyltrimethoxysilane into a reactor, heating and stirring, heating to 30-40 DEG C, dropwise adding a mixed solution of ultrapure water and a first solvent by using a constant-pressure funnel, S2, after dropwise adding is completed, carrying out heat preservation reaction for 2-3 hours at 30-40 DEG C, and adding a neutralizer when the water content is detected to be less than 1000 ppm; and S3, carrying out rectification to remove low-boiling-point impurities, and after rectification is completed, filtering a reaction solution to obtain a filtrate which is the coupling agent oligomer. The prepared coupling agent oligomer can prolong the storage life, can improve the bonding effect of EVA and glass when being used as a coupling agent, prolongs the service life of a solar cell, and improves the efficiency of converting light energy into electric energy.

Description

technical field [0001] The invention relates to a silane coupling agent, in particular to a coupling agent oligomer for enhancing bonding performance and a preparation method thereof. Background technique [0002] In the context of global warming, deterioration of the human ecological environment, and shortage of conventional energy sources, sustainable development strategies have been accepted by countries all over the world. Solar energy has the advantages of cleanliness, safety, and resource adequacy. It is one of the most important new energy sources in the 21st century and has been valued and supported by governments of all countries. [0003] The solar cell module is the core part of the solar power generation system, and the core of the photovoltaic module is the cell, which itself has a service life of more than 30 years. The performance reliability of the solar cell module in the long-term outdoor environment is mainly determined by the component Packaging film. S...
