Abstract
The invention discloses a double-component silane modified polyether adhesive, a preparation method and application thereof, belonging to the technical field of high polymer materials; the two-component silane modified polyether adhesive provided by the invention is characterized in that a mixture is formed by selecting acrylic ester and plasticizer with certain structures, and the component A and the component B are reasonably matched, so that the two-component silane modified polyether adhesive has good mechanical property and storage stability, and also has good adhesive property to materials with low surface energy, and meanwhile, the two-component silane modified polyether adhesive provided by the invention has the advantages of high curing speed, low odor and excellent storage property. In addition, the preparation method of the double-component silane modified polyether adhesive provided by the invention is simple to operate and is beneficial to actual production.
Description
Technical Field
The invention belongs to the technical field of high polymer materials, and particularly relates to a double-component silane modified polyether adhesive and a preparation method and application thereof.
Background
Along with the continuous expansion of market volume in the new energy automobile industry, the demand of power batteries is also growing. The main forms of the power battery cells in the market at present are square cells, soft package cells and cylindrical cells. In the assembling process of the power battery, the adhesive is needed to be used for realizing the bonding and fixing between the battery cells, the foam, the battery cells and the module shell and between the battery cells and the condensing plate. Because high-frequency vibration can be generated in the running process of the automobile, and a great amount of heat can be generated in the charging and discharging process of the power battery glue, the bonding strength and the fatigue resistance of the power battery glue at high temperature are particularly critical. At present, insulating blue films are adopted on the surfaces of mainstream square power batteries in the market to improve the insulativity of the square power batteries, and belong to polymer materials which are difficult to bond. The main stream of the two-component polyurethane structural adhesive on the market at present has poor adhesion to an insulating blue film.
Silane-modified polyether resins have been widely used in the construction and industrial fields due to their excellent properties, but silane-modified polyether products on the market are mainly used for elastic adhesion and sealing with low strength. The characteristics of low curing speed, low strength and the like limit the application of the silane modified polyether product in the field of power batteries. Epoxy adhesive bonding is widely applied in the industrial field as a high-strength fast-curing adhesive, but the toughness of the epoxy adhesive is poor, the elongation at break is generally not more than 10%, and the application of the epoxy adhesive in the battery field is limited.
The Chinese patent CN115558452A discloses a double-component adhesive for bonding a power battery and a preparation method thereof, and the double-component adhesive comprises a component A and a component B, wherein the component A comprises the following raw materials in parts by weight: 25-35 parts of silane modified polyether polymer, 20-30 parts of powder, 25-35 parts of inorganic flame retardant filler, 2-5 parts of epoxy curing agent, 1-3 parts of cross-linking agent and 2-5 parts of coupling agent; the component B comprises the following raw materials in parts by weight: 20-25 parts of organosilicon modified bisphenol A epoxy resin, 5-10 parts of plasticizer, 55-65 parts of inorganic flame retardant filler, 1-2 parts of thixotropic agent and 1-2 parts of catalyst. The adhesive has no water added in the component B, the curing of the silane modified polyether polymer in the component A mainly depends on the water in the filler in the component B, if the water content of the component B is too high, the storage stability of the component B can be reduced, and if the water content of the component B is low, the curing speed of the silane modified polyether can be slow. The double-component silane modified polyether adhesive for bonding wind power blade cover plates disclosed in Chinese patent CN108048015B is characterized in that epoxy resin and silane modified polyether are both arranged in the component A, but the compatibility of the epoxy resin and the silane modified polyether is common, the phase separation is easy to occur, an ideal interpenetrating network structure cannot be formed, the strength of a final product is low, and the bonding performance to low-surface-energy materials is poor. Meanwhile, in order to realize faster curing speed when the epoxy resin is used, tertiary amine epoxy curing accelerators such as DMP-30 and the like are adopted, so that the epoxy resin has a large taste and is not friendly to the preparation environment.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a double-component silane modified polyether adhesive with excellent storage stability, high mechanical strength, good adhesive property, low smell and high curing speed, and a preparation method and application thereof.
To achieve the above object, in a first aspect of the present invention, there is provided a two-component silane-modified polyether adhesive comprising an a-component and a B-component;
the component A comprises the following components in parts by mass: 50-80 parts of silane modified polyether, 10-40 parts of a mixture of acrylic ester and plasticizer, 30-60 parts of epoxy resin, 40-80 parts of flame retardant filler, 0.5-2 parts of ultraviolet auxiliary agent, 0.5-2 parts of antioxidant, 0.5-2.5 parts of thixotropic agent, 0.5-2 parts of toner and 1-5 parts of water scavenger;
