Problems solved by technology

[0002] The technology of perovskite materials is becoming mature, but there is a lack of simple and effective packaging materials
For perovskite materials, their sensitivity to oxygen and water vapor is much higher than that of existing crystalline silicon and thin film components, so conventional packaging materials such as EVA, POE or PVB, etc., and conventional butyl rubber seals, The effect of blocking water vapor is acceptable, but it has no special blocking and sealing effect on oxygen, which leads to the failure of organic photoelectric materials to be easily oxidized by oxygen and cannot be mass-produced.

preparation example Construction

[0032] The preparation method of oxygen barrier butyl rubber in the specific embodiment comprises the steps:

[0033] Reinforcing fillers and filling fillers are first dehydrated in a vacuum oven at 150°C for 2 hours;

[0034] Add butyl rubber, tackifier, silane-modified olefin polymer, reinforcing filler, and filling filler into the kneader according to parts by weight, control the temperature within the range of 100-140°C, knead into agglomerates and vacuumize for 30 Minutes, control the vacuum degree ≤ -0.09MPa;

[0035] Then add the barrier filler to the mixture obtained in step (1), mix quickly and evenly, knead under the protection of carbon dioxide or argon until uniformly formed into agglomerates, the kneading temperature needs to be adjusted according to the type of barrier filler added: when using reduced iron powder , It is necessary to cool down the kneader to between 80°C and 100°C in advance, and at the same time, it needs to be filled with inert gas for more th...

Abstract

The invention discloses an oxygen barrier butyl rubber and a preparation method thereof. The butyl rubber includes the following components in parts by mass: 100 parts of butyl rubber; 10-40 parts of tackifier; 2-10 parts of silane-modified olefin polymer; 2-15 parts of reinforcing filler; 2-15 parts of barrier filler 20 parts; 10‑40 parts for filler. Wherein, the barrier filler includes one or a combination of reduced iron powder, 4A molecular sieve, and carbon molecular sieve. The oxygen barrier butyl rubber of the invention has the advantages of high oxygen barrier efficiency, low oxygen transmission rate, etc., and the preparation process is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of butyl rubber, in particular to an oxygen-resistant butyl rubber and a preparation method thereof. Background technique [0002] The technology of perovskite materials tends to be mature, but there is a lack of simple and effective packaging materials. For perovskite materials, their sensitivity to oxygen and water vapor is much higher than that of existing crystalline silicon and thin film components, so conventional packaging materials such as EVA, POE or PVB, etc., and conventional butyl rubber seals, The effect of blocking water vapor is acceptable, but there is no special blocking and sealing effect for oxygen, which leads to the failure of organic photoelectric materials to be oxidized by oxygen and cannot be mass-produced. [0003] Therefore, there is an urgent need to develop a material that has a better oxygen barrier effect and meets the existing photovoltaic lamination and packaging processes, ...
