AI Technical Summary

Problems solved by technology

Therefore, people have developed emulsion-based adhesives, which can also be used as jointing agents. Because they do not contain cement, there is no risk of efflorescence, but the operation time is still very short. In summer, the surface will be crusted within 3-5 minutes.
Based on these defects of the prior art, the current cement-based adhesives and / or emulsion-based adhesives still cannot meet the construction requirements of soft porcelain

Abstract

The invention provides a paste special adhesive for soft porcelain with sticky hook and its preparation method. The paste special binder for soft porcelain with sticky hook includes 20-25% of polyurethane modified acrylic emulsion and film-forming aids. 0.6‑0.8%, fungicide 0.2‑0.3%, antifreeze 0.5‑0.6%, defoamer 0.2‑0.3%, 300‑400 mesh heavy calcium carbonate 40‑45%, 80‑120 mesh sand 25‑37%, 5.6-6% of cellulose pulp, 0.7-0.8% of thixotropic agent; the polyurethane modified acrylic emulsion is a monomer containing polyurethane group, with a urethane bond, and a solid content of (40 ± 2%) vinyl acrylic emulsion. The paste special adhesive for soft porcelain with sticky hook has long operating time, anti-cracking in winter, improved bonding strength, avoids the problem of efflorescence, excellent weather resistance, waterproof, stain resistance and other good performances, overcoming the existing There are technical flaws.

Description

technical field [0001] The invention relates to the technical field of painting, and more particularly, to a paste-like adhesive-hook-integrated soft porcelain special adhesive and a preparation method of the paste-like adhesive-hook integrated soft porcelain special adhesive. Background technique [0002] Most of the existing soft porcelain binders are cement-based, which are shipped to the construction site in dry powder bags, and then workers add water to prepare them on site. Since it is difficult to equip the construction site with accurate weighing equipment such as electronic scales, most workers are based on their own needs. There is uncertainty in the strength of the binder, but it is not possible to add water during factory production, because there is cement, so the binder will quickly solidify. And because the cement-based adhesive is prone to efflorescence after it rains, this adhesive cannot be used as a jointing agent, and it cannot be used for bonding and joi...
