Abstract

The invention relates to a sealant for acrylic ester modified solar photovoltaic module and a preparation method thereof. The sealant is prepared from the following raw materials in parts by weight: 90 parts of alpha, omega-dihydroxy polydimethyl siloxane, 10-15 parts of acrylic ester, 0.5-0.8 part of catalyzer A, 0.8-1.2 parts of catalyzer B, 20-30 parts of activated calcium carbonate, 25-60 parts of silicon powder, 4-6 parts of fumed silica, 11-15 parts of crosslinking agents, 2-3 parts of silane coupling agents and 5-8 parts of plasticizer. The invention has the advantages that the permeation of water vapor can be inhibited effectively, and the permeation rate of the water vapor is less than 1; due to the adoption of ester modification by acrylic ester, no monomer is separated in the process of solidification and after solidification; the resistance to weather and corrosion is ideal; and the process of the recommended preparation method is simple, which is not strict on process requirements and equipment.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a sealant for acrylate-modified solar photovoltaic modules, and also relates to a preparation method of the sealant. Background technique [0002] Solar photovoltaic modules are also called solar cell modules. The sealants used for solar photovoltaic modules have been reported in Chinese patent documents, including two-component and single-component sealants. The condensation-type two-component sealant disclosed in CN1528821A, the one-component sealant such as the one-component silicone sealant for solar cell modules introduced in the invention patent application publication number CN101353563A and its preparation method. [0003] The aforementioned latter patent application has pointed out the deficiency of the previous patent application (the 7th-9th line of the background technology column on the first page of the description of CN101353563A), and is also...
