Document Type and Number:
WIPO Patent Application WO/2020/119147
Kind Code:
A1
Abstract:
Disclosed are a bicomponent epoxy mortar for pasting PVC and treating concrete expansion joints, a preparation method therefor and the use thereof. The raw materials of the epoxy mortar comprise a component A and a component B. The raw materials of the component A comprise an epoxy resin and a first auxiliary agent, and the raw materials of the component B comprise a curing agent and a second auxiliary agent, wherein the curing agent is composed of a modified polyether amine and a modified fatty amine. The modified polyether amine is made by reacting a polyether amine curing agent, an alkylphenol and 2,4,6-tris(dimethylaminomethyl)phenol, and then reacting same with benzyl alcohol, and the modified fatty amine is made by reacting octyl glycidyl ether and triethylene tetramine. The preparation method therefor comprises: first separately preparing the components A and B, and then mixing same until uniform to obtain the product. Also disclosed is the use of the epoxy mortar in pasting PVC and treating concrete expansion joints. The epoxy mortar of the invention has excellent adhesion with PVC, has both excellent mechanical properties and durability, and also has a good workability, and can adapt to the dynamic deformation of concretes.
