Problems solved by technology

Oil-based two-component beautifying agent is a water-insoluble polymer formed by epoxy resin through ring-opening cross-linking and curing by amine curing agent containing active hydrogen. It has the advantages of good adhesion, high strength, and smooth surface. However, it is not environmentally friendly enough, it is prone to cracking after curing, and it does not have the function of erasing water, which is not conducive to subsequent cleaning.
The existing commercially available ceramic tile epoxy grouting agents are often difficult to balance adhesion, durability and environmental performance
[0004] Chinese patent application CN 107353857 A discloses an epoxy beauty joint composition, including A component and B component, wherein A component includes raw materials such as epoxy resin, toughening agent, diluent, dispersant and filler, Component B includes polyetheramine, alicyclic amine, triethanolamine, diluent and filler. It has good bonding and anti-cracking performance, but there is a problem that the composition is relatively complicated, and the epoxy beauty sealant composition provided is not With water erasable function

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to a water-based beautifying agent and a preparation method thereof. Background technique [0002] Ceramic tiles, mosaics and other materials are widely used in the field of architectural decoration, and it is necessary to leave gaps between each piece of material and at corners when laying. Traditional joint fillers mainly use white cement, etc., which have the advantages of simple construction and low cost, but their durability is poor, and they are prone to chalking and blackening over time, and there are problems in environmental protection and sanitation. Insufficient, poor overall performance. [0003] With the development of technology, oil-based two-component beautifying agent has gradually replaced white cement for filling. Oil-based two-component beautifying agent is a water-insoluble polymer formed by epoxy resin through ring-openi...
