Abstract
The invention discloses polyarylether ethernitrile modified phenolic resin adhesive and a preparation method thereof. The polyarylether ethernitrile modified phenolic resin adhesive is technically characterized by being composed of the following substances in parts by weight: 50-60 parts of polyarylether ethernitrile modified phenolic resin, 6-10 parts of polyvinylpyrrolidone, 25-35 parts of butadiene-acrylonitrile rubber, 0.1-1 part of an anti-aging agent and 10-15 parts of methyl acetate. The polyarylether ether nitrile modified phenolic resin adhesive has the advantages that phenolic resin is modified by utilizing polyarylether ether nitrile, so that toughness and bonding performance of the phenolic resin are obviously improved; meanwhile, polyvinylpyrrolidone has good molecular affinity, so that polyarylether ether nitrile, butadiene-acrylonitrile rubber and phenolic resin form a uniform system, and toughness of a material is improved; besides, the polyvinylpyrrolidone has excellent bonding performance, so that coadhesiveness of the phenolic resin adhesive is also further improved.
Description
technical field [0001] The invention relates to the technical field of adhesives, in particular to a polyarylether ether nitrile modified phenolic resin adhesive and a preparation method thereof. Background technique [0002] The production process of phenolic resin material is simple, the price is cheap, and it has a wide range of applications. It is one of the indispensable polymer materials for my country's industrial development. However, traditional phenolic resins are brittle and easily broken during use, which limits their application in the field of high-performance materials. Therefore, modifying phenolic resin materials to improve their toughness is very important to the development of high-tech fields in my country. At present, the toughening modification method of phenolic resin is mainly by adding rubber, thermoplasticpolymer materials, glass fibers, nano-powder, etc. to phenolic resin, but there are usually some problems in the addition of these materials, in...
