TBS anti-oxidation edge sealing adhesive and preparation method thereof

Abstract

The invention discloses a TBS anti-oxidation edge sealing adhesive and a preparation method thereof. The method comprises the following steps: step 1, sequentially adding modified aromatic amine, an imidazole compound, mixed epoxy resin, a low-shrinkage agent and a fireproof solution into a reaction kettle, dropwise adding a tib metal catalyst with a concentration of 9% under the condition of stirring, conducting reacting for 20 minutes at 90 DEG C, raising the temperature to 120 DEG C, conducting reacting for 30 minutes, after the reaction is finished, distilling the mixture under the condition of reduced pressure, and conducting standing for 30 minutes at normal temperature to obtain a mixture I; and step 2, mixing the mixture I, vinyl silicone oil and hydrogen-containing silicone oil, conducting heating to 60-75 DEG C, adding methyl ethyl ketone peroxide, conducting constant-temperature stirring reaction for 40-60 min, and conducting filtration. The TBS anti-oxidation edge sealing adhesive and the preparation method thereof have the advantages that the TBS anti-oxidation edge sealing adhesive is high in heat conductivity, good in flame retardancy, good in adhesive property and the like, a heat conducting filler, a flame retardant and an adhesive are added and do not cause adverse effects on the mechanical property, the processability and the like of colloid, and the colloidcan achieve corresponding insulation effects.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a TBS anti-oxidation edge banding adhesive and a preparation method thereof. Background technique [0002] There are many types of adhesives, including acrylate adhesives, polyurethane adhesives, epoxy resin adhesives and UV adhesives, etc. Due to the physical properties, adhesive strength and composition of different colloids The difference in composition and other aspects leads to the application of products in different fields. Generally, the detection of colloids often distinguishes product quality from four aspects: physical properties, chemical properties, mechanical properties and aging properties. Among them, TBS edge banding adhesive As far as the product is concerned, it is often used in the edge banding work of the mirror surface. The edge banding adhesive can form a complex with silver, passivate the silver into a passivation layer, and be more difficult to be oxidi...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of TBS anti-oxidation edge sealing adhesive and preparation method thereof, to solve the shortcomings such as low thermal conductivity, flame retardancy and poor bonding performance in the above-mentioned background technology, resulting in a small range of applications, although through a large number of Adding thermally conductive fillers, flame retardants and adhesives can improve the performance of potting adhesives, but it will adversely affect the mechanical properties and processing properties of the colloids; the addition of shrinkage agents is not reasonable enough, resulting in poor concentration ratios of the main mixture; The colloid cannot achieve the corresponding insulating effect, resulting in a narrowing of the application range; the cured colloid is prone to cracking under the action of external force, and there is no cushioning problem at all.
