Problems solved by technology

Some of these methods stay in the laboratory stage (such as: the method of interpenetrating network toughening EP), and some although the toughening effect is good, but sacrifice some good performance characteristics of EP (such as: after adding the toughening of the island structure , the effect of impact resistance and toughening is obviously improved, but the heat distortion temperature is lowered to make it lose its competitiveness. Another example is the addition of active rubber such as polysulfide rubber blended with toughened EP. The effect is ob

Example Embodiment

[0013] Accompanying drawing is the production process reference figure of the present invention, and the production method of a kind of nano styrene-butadiene rubber modified epoxy resin of the present invention is as follows:

[0014] The first step: Mix the nano-styrene-butadiene pyrene rubber in the component with the dispersant, and perform pre-dispersion by anchor stirring with temperature control and speed regulation after activation. The temperature is controlled at 30-40°C, the stirring speed is 800-1000 revolutions per minute, and the time is two minutes.

[0015] Step 2: Add epoxy resin, coupling agent, defoamer, leveling agent and accelerator to the material after the first step according to the component ratio for pre-soaking.

[0016] Step 3: Grind and roughly disperse the pre-soaked material in the second step.

[0017] The fourth step: Grinding and finely dispersing the materials after the third step.

[0018] The fifth step: finely disperse the material after...

Abstract

The invention provides nanometer butadiene-styrene-vinyl pyridine rubber modified epoxy resin, aiming at providing nanometer butadiene-styrene-vinyl pyridine rubber modified epoxy resin which has high rigidity, tenacity and thermal endurance and can not lower the other properties. The epoxy resin comprises the following components in percentage by weight; 8-15% of nanometer butadiene-styrene-vinyl pyridine rubber, 72-78% of epoxy resin, 3-4% of dispersing agent, 3-4% of coupling agent (also called as surface treating agent), 3-4% of accelerator, 1-2% of defoamer and 1-2% of flatting agent. The epoxy resin is prepared by the method comprising the following steps: mixing the nanometer butadiene-styrene-vinyl pyridine rubber and the dispersing agent; activating the mixture and carrying out temperature control, speed regulation and anchor mixing; mixing the mixture with the other components, and presoaking; and then obtaining the epoxy resin by carrying out the three working procedures, namely coarse grinding, fine grinding and refined grinding.

Description

technical field [0001] The invention relates to a modified epoxy resin and a production method thereof, in particular to a nano-styrene-butadiene pyridine modified epoxy resin and a production method thereof. Background technique [0002] Epoxy resin (hereinafter referred to as EP) refers to an organic polymer compound containing two or more epoxy groups in the molecule, and its structure is characterized by active epoxy groups in the molecular chain. This enables them to undergo cross-linking reactions with various types of curing agents to form insoluble, infusible high polymers with a three-dimensional network structure, and thus become the most widely used resin system in some modern new materials. General-purpose EP, as a thermosetting resin, is more and more widely used in rubber base materials, sealing insulation, vehicles, building structures, fiber Composite, military aviation and other fields are one of the most important materials in industry now. At the same ti...
