Example Embodiment

[0052] The preparation method of the following two-component adhesive includes the following steps:

[0053] S1. Weigh the raw materials according to the formula of the following examples 1-8;

[0054] S2. Stir the epoxy resin and reactive diluent evenly, then add nano calcium carbonate and powder fillers, and stir into a uniform paste. The stirring speed is 60 rpm, the time is 1 h, and the stirring temperature is 20 ℃. Obtain the A component;

[0055] S3. Stir the modified amine curing agent and dispersant evenly, then add nano calcium carbonate and powder filler, and stir into a uniform paste. The stirring speed is 60 rpm, the time is 1 hour, and the stirring temperature is 20°C. , And then get the B component;

[0056] S4. Mix the well-stirred component A and component B and stir for 45s to obtain a two-component adhesive.

Abstract

The invention relates to the adhesive field, and in particular, relates to a two-component adhesive and a preparation method thereof. The two-component adhesive is mainly composed of a component A and a component B, wherein the component A comprises the following raw materials in parts by mass: 18-35 parts of epoxy resin, 3-82 parts of nano calcium carbonate, 0-5 parts of an active diluent and 0-82 parts of a powder filler; the component B comprises the following raw materials in parts by mass: 18-35 parts of a modified amine curing agent, 3-82 parts of nano calcium carbonate, 0-5 parts of a dispersant and 0-82 parts of a powder filler; the component A and the component B are in mixed use with the mass ratio of (1.5-2.5):1. The two-component adhesive provided by the invention has the advantages of low toxicity, environmental protection, aging resistance, good thixotropy and high strength.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a two-component adhesive and a preparation method thereof. Background technique [0002] Adhesive refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives, which has the characteristics of continuous stress distribution, light weight, and low process temperature. Adhesive is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. It has developed rapidly in modern times and has a wide range of application industries. It has a major impact on the progress of high-tech science and technology and the improvement of people's daily life. Adhesives can be divided into thermosetting type, hot melt type, room temperature curing type and pressure sensitive type according to the application method; according to the components, they can be divided into one-component, two...
