Abstract

The invention discloses a resin composite material and a preparation method thereof, relating to a composite material of nanometer organobentonite and rubber and resin, and the preparation method thereof. The invention studies the blending and modification of styrene butadiene and rubber and nanometer organobentonite: by using the characteristic of ion exchange of bentonite, the nanometer organobentonite is prepared by the ion exchange between an intercalation agent and the bentonite. The bentonite enlarges the interlayer distance and improves the compatibility with polymers. Then the melt-compounding method is adopted to study the intercalation compounding of the modified bentonite and rubber and four resins, and the modified bentonite and the maleic anhydride-grafted of rubber and four resins at high temperature. The preparation method and the manufacturing technique are simple, and the composite materials have good mechanical properties and easy application in the industrial production, thus providing a fundamental study for the industrial production.

Description

technical field [0001] The invention relates to a resin composite material and a preparation method thereof, in particular to an intercalation compound of nano-organic bentonite, rubber, and four kinds of resins and a preparation method thereof. Background technique [0002] Bentonite belongs to the monoclinic crystal system and is a 2:1 layered silicate mineral composed of two layers of silicon-oxygen tetrahedrons and a layer of Al(Mg)O(OH) octahedral sheets sandwiched between them. Among them, the silicon-oxygen tetrahedral system is composed of the three vertices of the silicon-oxygen tetrahedron in the same plane, which are shared with the adjacent silicon-oxygen tetrahedrons to form a series of silicon-oxygen sheets with approximate hexagonal ring grids; Al(Mg)O(OH)8 The facet sheet is a hexacoordinated Al(Mg)O(OH) octahedron with Al(Mg) as the central atom, and two hydroxyl groups in the same plane as the four apex oxygens of the tetrahedrons opposite to each other. A...
