Problems solved by technology

[0004] However, the polyurea beautifying agent currently on the market shrinks severely after curing, and often requires secondary filling, which wastes manpower and material resources, and may also affect the strength of the caulking surface.
The main reasons for the shrinkage phenomenon are: ①The solid content in the beautifying agent is low, resulting in a large shrinkage rate after curing; ②Aspartic polyurea has a regular structure, and a large number of hydrogen bonds have a tendency to crystallize after orientation, resulting in shrinkage; ③Ester And urea groups can form a conjugated five-membered ring, resulting in greater shrinkage after curing

Description

technical field [0001] The invention relates to the technical field of caulking agents, in particular to a low-shrinkage caulking agent and a preparation method thereof. Background technique [0002] In recent years, the domestic decoration field has developed rapidly, and people's requirements for home decoration are getting higher and higher, especially in the beautification and decoration of the gaps between decorative materials, more and more attention has been paid. In the decoration process, the traditional process usually chooses jointing agent, joint filling agent or white cement to fill. These jointing materials are monotonous in color and complicated in construction process, and are prone to problems such as yellowing, blackening, and mildew. The development of the decoration industry has been greatly restricted. [0003] As an upgraded product of jointing agent, beauty jointing agent is a new type of adhesive for gap decoration that has emerged in recent years. I...
