Abstract

The invention provides a low-viscosity normal-temperature-curable two-component epoxy glue. The low-viscosity normal-temperature-curable two-component epoxy glue comprises an epoxy material (a component A) and a curing material (a component B), wherein the epoxy material comprises the following components by weight: 82.2 to 88% of epoxy resin, 3.5 to 6% of benzyl alcohol, 0.5 to 0.8% of an organosilicone antifoaming agent, 4.0 to 5.0% of fumed silica, 0.5 to 1.0% of a color paste and 3.5 to 5% of pearl powder; and the curing material comprises the following components by weight: 75 to 85% of amodified amine curing agent, 5 to 10% of epoxy resin and 10 to 15% of benzyl alcohol. The low-viscosity normal-temperature-curable two-component epoxy glue provided by the invention has the followingbeneficial effects: the epoxy glue provided by the invention has the characteristics of low viscosity, curability at a normal temperature, adjustable color, high glossiness after curing of the glue,etc., and is simple in preparation process and simple, convenient and rapid in operation and application; and a quartz clock frame prepared by using the low-viscosity normal-temperature-curable two-component epoxy glue provided by the invention has various colors and strong three-dimensional sense, and the appearance and grade of a quartz clock are improved, so the quartz clock has better market prospect.

Description

technical field [0001] The invention relates to a low-viscosity normal-temperature curing two-component epoxy glue and a preparation method thereof, belonging to the technical field of high-performance epoxy glue. Background technique [0002] Quartz clock is a household product widely used in daily life. At present, the outer frame of the quartz clock is mainly made of acrylic injection molding, and the outer frame is electroplated to achieve a beautiful effect. However, the electroplating process will produce environmental pollution such as noise, waste liquid, and exhaust gas, and the appearance of the electroplating frame is not high in color and brightness, and its style is relatively simple. [0003] Therefore, the present invention provides a low-viscosity room temperature curing two-component epoxy glue for the outer frame of a quartz clock and a preparation method thereof to obtain a quartz clock outer frame with various colors and a strong three-dimensional effect...
