Problems solved by technology

[0002] Slate is an emerging decorative material in the building materials industry. The maximum size can reach 3.2m*1.6m, and the thickness is between 3 and 12mm. Slate is composed of silica, inorganic clay, and feldspar powder, which are rolled and fired. It has the disadvantage of being fragile, and the slabs are very easy to break during the application and transportation of walls, floors, furniture countertops and other scenes
[0003] Although the stone back mesh adhesive and coated back mesh process existed earlier in the stone industry (that is, after the stone back mesh adhesive is coated and then pressed), it is not suitable for rock slabs because the stone is relatively small in size (the largest size is generally 1.2m*0.6m), at the same time, the stone production is small and the demand is small, so it is generally possible to manually scrape and apply paste-like stone backing glue, and then let it stand for 24 hours to cure; if it is applied to rock slabs, there will be paste Stone glue is difficult to operate on the assembly line, slow production efficiency, and high labor costs. At the same time, ordinary stone back mesh glue has a strong smell, and the plasticizer continues to volatilize even after curing, which affects human health; in addition, due to the volume of stone Considering the small size and application scenarios, the pot life of traditional stone backing glue is not enough, and the requirements for strength and hardness are not high. The mesh glue is also completely unable to meet the requirements of the rock plate for pot life, hardness and strength

Abstract

The invention discloses a rock slab backing glue, a preparation method and a coating process thereof. The rock slab backing glue is composed of A component and B component with a volume ratio of 2:1; the A component includes epoxy Resin, reactive diluent, non-reactive diluent, leveling agent, defoamer, silane coupling agent; B component includes: non-reactive diluent, curing agent, bactericide, accelerator, preservative; Component and B component are mixed to prepare the slate back mesh adhesive, and then the slate back mesh is formed by coating on the surface of the slate and spreading. The slate back mesh adhesive proposed by the present invention is odorless, has good cohesiveness, stability, acid and alkali resistance and extremely low curing shrinkage rate, and does not need high temperature curing, and has faster curing speed and longer pot life , better hardness and strength; its preparation method and coating process are simple and easy to operate, and can be applied to automatic mechanical operations in assembly lines, greatly reducing labor costs and improving production efficiency.
