Problems solved by technology

Among them, unsaturated polyester uses styrene as active diluent, which has poor environmental performance and yellowing resistance; while ordinary epoxy resin has poor permeability and yellowing resistance, and its curing performance under low temperature and humid conditions is not ideal.
As ordinary marble, high-grade marble, and jade are more and more applied to architectural decoration, the existing stone repair surface glue, its yellowing resistance performance cannot meet the requirements of white marble, light-colored marble, etc. discoloration requirements

Abstract

The present invention relates to a yellow-resistance and rapid-curing stone material repair surface glue, a preparation method and a use method thereof. The yellow-resistance and rapid-curing stone material repair surface glue comprises a component A and a component B, wherein the component A comprises, by weight, 3-4 parts of a main body, 0.5-1.0 part of an adhesion promoter, 0.05-0.1 part of phosphate, 0.005-0.01 part of an antifoaming agent, 0.01-0.02 part of a coupling agent and 0.5-1.0 part of a diluent, the main body is polyaspartate having a hydroxyl equivalent mass content of 6.1-7.4%, the adhesion promoter is polyaspartate having a hydroxyl equivalent mass content of 4.2-6.0%, and the component B comprises a nonaromatic isocyanate. According to the present invention, the main body and the adhesion promoter are subjected to combined use, such that the problems that the resin using the high hydroxyl equivalent mass content polyaspartate as the main body provides poor adhesion and poor permeability to the substrate and has short application period are effectively solved, and the obtained yellow-resistance and rapid-curing stone material repair surface glue has characteristics of rapid curing, good yellowing resistance, good adhesion, good permeability, and high bond strength.

Description

technical field [0001] The invention relates to the field of material science and technology, in particular to a yellowing-resistant and fast-curing stone repair surface glue, a preparation method and a use method thereof. Background technique [0002] At present, unsaturated polyester resin and ordinary epoxy resin are commonly used in stone repair surface glue. Among them, unsaturated polyester uses styrene as active diluent, which has poor environmental performance and yellowing resistance; while ordinary epoxy resin has poor permeability and yellowing resistance, and its curing performance under low temperature and humid conditions is not ideal. As ordinary marble, high-grade marble, and jade are more and more applied to architectural decoration, the existing stone repair surface glue, its yellowing resistance performance cannot meet the requirements of white marble, light-colored marble, etc. Discoloration on request.
