Abstract

A nanometer type epoxy resin composite insulating material of an automobile high-voltage ignition coil is prepared by the following steps: adding nanometer Si3N4 in an acetone solution in which a coupling agent is solved, conducting high speed dispersion, and placing formed suspension in an oscillation box to oscillate; mixing the solution obtained from the last step with epoxy resin and diluent; conducting high speed dispersion for 40min and then ultrasonic dispersion for 30 min and removing solvent; after cooling, adding polyamide and mixing the mixture to uniform; after exhausting and degassing, pouring the mixture in a self-made mold which is coated with a release agent and pre-heated well, and demolding after 3h at 60 DEG C and 2h at 100 DEG C, thus preparing Si3N4/epoxy resin nanometer composite material; conducting melting-compositing or in-situ polymerization on the basis; and filling one or multiple types of nanometer materials of phyllosilicate, nanometer mica, nanometer tubes or nanometer clay, thus preparing the epoxy resin composite insulating material. The service performance of the automobile high-voltage ignition coil is improved.

Description

technical field [0001] The invention relates to an insulating material, in particular to a nano-type automobile high-voltage ignition coil epoxy resin composite insulating material. Background technique [0002] Epoxy resin is a general-purpose adhesive with excellent bonding properties. But because it is liquid and has a high viscosity, and most commonly used epoxy adhesives are two-component, that is, composed of epoxy resin and curing agent. Usually the use of two-component adhesive systems is inconvenient and cannot be used directly on the bonding surface. At the same time, the traditional epoxy resin adhesive also has the following disadvantages. When it is not toughened, the cured product is generally brittle, with poor peeling resistance, crack resistance, and impact resistance; Plastics, etc.) have low adhesion, and surface activation treatment must be carried out first. Some reactive diluents, curing agents, etc. have varying degrees of toxicity and irritation. ...
