preparation example Construction

[0046] The preparation method of the organic bentonite in the present invention is as follows:

[0047] (1) Add 10g of sodium bentonite and 500ml of distilled water into a beaker, stir for 30 minutes, and let stand at room temperature for 24 hours to remove a small amount of impurities at the bottom of the bottle;

[0048] (2) Stir in a constant temperature water bath at 70°C for 3 minutes, and add 2 ml of a sulfuric acid solution with a mass fraction of 2%;

[0049] (3) Dissolve 8.2g of cetyltrimethylammonium chloride in 8.2ml of isopropanol or 11.1g of dioctadecyldimethylammonium chloride in 11.1ml of isopropanol, and then Add the resulting solution dropwise to the beaker, and continue to stir for 1h / 1.5h;

[0050] (4) After standing for stratification, take the flocculent solids, filter with suction and wash repeatedly with distilled water for several times, until there is no Cl - (0.1mol1L AgNO 3 After the solution is checked for no white precipitation), it is vacuum dried to cons...

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 composite of nano organic bentonite, rubber, and four resins and a preparation method thereof. Background technique [0002] Bentonite belongs to the monoclinic crystal system, which is a 2:1 type layered silicate mineral composed of two layers of silicon-oxygen tetrahedrons and a layer of Al(Mg)O(OH) octahedral sheets sandwiched between them. The silicon-oxygen tetrahedron system consists of the three apex oxygens of the silicon-oxygen tetrahedron in the same plane and the adjacent silicon-oxygen tetrahedrons, which are connected to form a series of silicon-oxygen wafers that approximate a hexagonal ring grid; Al(Mg)O(OH) The faceted sheet is made of Al(Mg) as the central atom, and the four apexes of the tetrahedron opposite to each other. The two hydroxyl groups whose oxygen is on the same plane constitute a six-coordinate Al(Mg)O(OH) oc...
