Problems solved by technology

Based on the above requirements, 1,3-BAC is mainly selected as the main alicyclic amine in the industry, while IPDA has limited application due to its strong moisture absorption, and HMDA has limited application due to slow surface drying time and inconvenient cleaning in time
[0004] The two-component epoxy beautifying agent disclosed in CN105802451A has the advantages of no flow, no sagging, and convenient construction, but has the disadvantage of poor toughness, which cannot meet the requirements of the northern winter to resist deformation due to thermal expansion and contraction
[0005] CN106634755A discloses a preparation method of epoxy-modified HMDA, the curing agent can improve the curing speed of HMDA in the field of beautifying agent, but the viscosity of the epoxy-modified curing agent is relatively large, it is difficult to mix the thixotropic agent, and it is difficult to Glue, very inconvenient for downstream construction
[0006] CN106957629A discloses a ceramic tile beautifying agent that meets higher requirements in terms of color, hardness and environmental protection, but it mainly adjusts the curing speed through DMP-30. The accelerator is particularly prone to yellowing and cannot meet the long-term durability Satisfactory effect

Abstract

The invention relates to an amine curing agent for a seam beauty agent and a preparation method thereof, and relates to an epoxy resin composition. The curing agent is prepared from modified HMDA, polyetheramine, epoxy resin and a diluent. When the curing agent is mixed with an A component at a room temperature, the surface of the mixture can be quickly dry, and after the mixture is actual dry, the spline can achieve the effects of being soft around fingers and being hard as porcelain, and the spline has higher weatherability, the epoxy curing agent is suitable for the seam beauty agent industry.

Description
