Problems solved by technology

If the natural curing method is adopted, due to the long curing time, a very large construction site is required to store the plates to be cured, and the site utilization rate is very low
Moreover, it is difficult to cure the back glue completely in the low temperature and humid climate in winter, which seriously affects the quality of the sizing board.
If the method of heating and curing in the drying room is adopted, not only the energy consumption is relatively large, but also the investment in the construction of the drying room is required, which increases the production cost
If it is a solvent-based adhesive resin, the environmental protection and production safety issues during the curing process are more prominent

Abstract

The invention discloses a double-frequency-spectrum cured natural stone back glue composition. The composition is prepared by taking carboxyl epoxy acrylic acid water-based resin and urethane acrylateprepolymer resin as main functional components and vegetable oil-based light-cured resin as an auxiliary component, adding aggregate, and adding a light curing agent and a surfactant. After the backglue composition is subjected to double-frequency-spectrum curing through ultraviolet light and infrared light, a formed back glue layer has enough rigid support degree and also has good flexibility and adhesive force; and when the composition is applied to natural stones as a substrate material, the strength of the stones can be improved, the damage rate in the processing, transportation and decoration processes can be prevented, cracking and falling of externally bonded stones caused by different cold shrinkage and thermal expansion rates of the stones and a wall body can be reduced, and thecomposition has comprehensive performance of rigidity and flexibility balance.

Description

technical field [0001] The invention relates to a natural stone adhesive, in particular to a dual-spectrum curing natural stone adhesive composition. Background technique [0002] Natural stone (including natural marble, granite, marble, jade, etc.) is a class of high-end building decoration materials, with beautiful appearance, elegant, luxurious, durable and durable materials, and is widely used in large public buildings, hotels, hotels, Decoration of cultural and entertainment facilities, noble residences, etc. [0003] Natural stones are collected from mines. On the one hand, due to geological and climate changes in the long history, the uniformity of stones is affected, and there are impurities and cracks; on the other hand, due to mechanical and external forces during mining, transportation and processing, stones Susceptible to damage, surface defects and cracking. In either case, various manual repairs and reinforcement measures are required. [0004] After natural...
