Abietinol-grafted composite elastic material and preparation method thereof

Abstract

The invention discloses an abietinol-grafted composite elastic material. The abietinol-grafted composite elastic material is prepared from the following raw materials in parts by weight: 0.3 to 1 part of beta-hydroxyalkylamide, 3 to 4 parts of 4-dimethylamino-pyridine, 1 to 2 parts of triethylamine, 0.1 to 0.3 part of 2-bromopropionyl bromide, 1 to 2 parts of 1-allyl-3-methylimidazolium chloride, 50 to 60 parts of methyl methacrylate, 10 to 13 parts of carbon nanotube, 40 to 51 parts of n-butyl acrylate, 0.7 to 1 part of copper bromide, 1.6 to 2 parts of pentamethyl diethylenetriamine, 1 to 2 parts of copper powder, 3 to 4 parts of abietinol, 3 to 4 parts of alkenyl succinate, 0.4 to 1 part of 2-octyl-3(2h)-isothiazolone, 1 to 2 parts of triethanolamine oleic soap, 5 to 7 parts of scolecite, 0.01 to 0.02 part of divinyl benzene, 2 to 3 parts of polytetrafluoroethylene wax, 0.5 to 1 part of tert-butylhydroquinone, 6 to 8 parts of tetrahydrofuran, and a proper amount of ethylene glycol, dimethyl formamide, chloroform, thionyl chloride and 95-98% nitric acid. The abietinol-grafted composite elastic material has the advantages that by adding the abietinol, the dispersing property of filler in resin is improved, the stability and strength of a finished product are improved, and the comprehensive property of the finished product is improved.

Description

technical field [0001] The invention relates to the technical field of elastic materials, in particular to an abietyl alcohol grafted composite elastic material and a preparation method thereof. Background technique [0002] Thermoplastic elastomer is a special polymer material, which is both elastic and plastic, and can be widely used in important fields of the national economy such as packaging materials, auto parts, adhesives, clothing, and biomedicine. Thermoplastic elastomers have a common feature, that is, they are almost all phase-separated systems. At room temperature, one phase is the rubber phase, and the other phase is the hard phase. The rubber phase with a very low glass transition temperature is used as the matrix, while the hard phase with a high glass transition temperature is dispersed in the rubber matrix as a dispersed phase and acts as a physical crosslinking point. For thermoplastic elastomers, the hard phase imparts strength to the elastomer, while the...

Problems solved by technology

There are many studies on the introduction of carbon nanotubes into elastomers by physical blending methods. However, there are few studies on the use of carbon nanotubes as initiation points for graft polymerization to prepare elastomers. One-pot method is carried out by chemical methods. Graft polymerization can effectively increase the interaction between nanofillers and the matrix, make them better dispersed in the matrix, significantly enhance their interfacial force, and further improve their performance. Therefore, it is important to prepare such high-performance thermoplastic elastomers. the actual meaning of
