Abstract

The invention discloses an oxidation-resistant high-strength binder and a preparation method thereof. The binder is prepared from the following raw materials by weight: 60 to 80 parts of polyurethane resin, 27 to 40 parts of methyl etherified amino resin, 18 to 25 parts of rosin pentaerythritol ester, 5 to 12 parts of vinyl chloride-vinyl acetate resin, 8 to 18 parts of tetraethylenepentamine, 6 to 13 parts of an anti-oxidant, 4 to 10 parts of a light stabilizing agent, 8 to 17 parts of fluorite powder, 6 to 14 parts of alumina, 5 to 11 parts of calcium persulfate, 2 to 6 parts of Tween-85, 25 to 40 parts of acetic ester, 12 to 26 parts of cyclohexanone and 8 to 16 parts of propylene glycol. The binder prepared in the invention has high tensile bonding strength and maintains good tensile bonding strength after thermal ageing at 136 DEG C for 168 h, showing good overall performance.

Description

technical field [0001] The invention belongs to the field of materials, in particular to an oxidation-resistant high-strength adhesive and a preparation method thereof. Background technique [0002] Adhesives, also known as binders and adhesives, are substances that can tightly bond two or more homogeneous or heterogeneous objects (or materials) together, and have sufficient strength at the joint after curing. The application of adhesives has penetrated into people's lives and is one of the indispensable raw materials in all walks of life. [0003] With the development of industrial economy, people have higher and higher requirements on the performance of binders. The traditional adhesive has a single component and cannot provide special properties to meet the application requirements of special occasions and environments, such as UV resistance, oxidation resistance, high bond strength, high wear resistance, high toughness, environmental protection and other properties.
