Abstract

The invention discloses a durable rubber plate for a photovoltaic laminating machine and a preparation method of the durable rubber plate. The durable rubber plate comprises the following components in parts by mass: 100 parts of a rubber matrix, 20-40 parts of a reinforcing filler, 5-10 parts of a vulcanizing agent, 1-6 parts of a vulcanizing aid and 1-5 parts of an anti-aging agent, wherein therubber matrix comprises hydrogenated butadiene-acrylonitrile rubber, fluororubber and ethylene propylene diene monomer. According to the durable rubber plate for the photovoltaic laminating machine and the preparation method of the durable rubber plate, the corrosion resistance, the oil resistance and the weather resistance of the rubber plate are improved through blending of hydrogenated butadiene-acrylonitrile rubber and fluororubber; through blending of ethylene propylene diene monomer rubber and use of the reinforcing filler, the toughness and mechanical strength of the rubber plate are improved, so that the rubber plate is endowed with excellent comprehensive performance, the service life of the rubber plate is prolonged, and the durability is improved.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to a durable rubber sheet for a photovoltaic laminator and a preparation method thereof. Background technique [0002] Laminator rubber sheets for solar photovoltaic cell module packaging are required to have properties such as wear resistance, corrosion resistance, and oil resistance. The existing rubber sheets suitable for the above purposes mainly include hydrogenated nitrile rubber sheets, silicone rubber sheets, and EPDM rubber sheets. These rubber sheets can satisfy the performance to a certain extent, such as corrosion resistance, oil resistance, etc., but in actual production and use, it is found that the strength and toughness of the rubber sheets are insufficient, and they are easily damaged after repeated use or cutting. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a durable rubber sheet for photovoltaic la...
