Abstract

The invention discloses an oxidation-resistant high-strength binder and a preparation method thereof. Wherein, the binder is prepared from the following raw materials, and is calculated in parts by weight: 60-80 parts of polyurethane resin, 27-40 parts of methyl etherified amino resin, 18-25 parts of rosin pentaerythritol ester, 5 parts of vinyl chloride resin ~12 parts, 8~18 parts of tetraethylenepentamine, 6~13 parts of antioxidant, 4~10 parts of light stabilizer, 8~17 parts of fluorite powder, 6~14 parts of alumina, 5~11 parts of calcium persulfate , Tween 85 2~6 parts, ethyl acetate 25~40 parts, cyclohexanone 12~26 parts and propylene glycol 8~16 parts. The adhesive prepared by the invention has high tensile adhesive strength, and after heat aging at 136° C.×168 h, the tensile adhesive strength still remains good, showing good comprehensive 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.
