Problems solved by technology

[0005] Using the existing ordinary marble glue as jointing glue will have the following disadvantages: ①. Poor air-drying property, sticky to hands after the colloid is cured
②. After polishing, the brightness of the colloid and the polished stone are inconsistent, and there is color difference
③. Poor shrinkage resistance, easy to form depressions or separate from the stone when the glue cures
④. Poor permeability, insufficient filling or voids

Abstract

The invention relates to special colored stone material caulking sealant, which at least comprises 100 weight parts of air-dried unsaturated polyester resin, 1 to 5 weight parts of hydrogenated castor oil, 10 to 250 weight parts of filling materials and 1 to 15 parts of antishrinking agents. The invention overcomes the defects of poor air-dried performance, low antishrinking capability, poor permeability and the like when the existing ordinary marble glue is used as the caulking sealant. The stone material caulking sealant of the invention has the advantages of good permeability, hand inadhesion after being cured, strong antishrinking capability, sealant brightness after grinding and the like. The invention enriches the variety of the marble glue, and solves the caulking problem between stone materials.

Description

technical field [0001] The invention relates to a stone pointing glue, which is mainly used for filling or filling the gaps between stone materials. It can also be used for pointing other building materials such as ceramics. Background technique [0002] Marble glue is unsaturated resin glue, because it is mainly used on marble, so it is called marble glue by domestic convention. It is mainly used for stone filling bonding (generally bears less load), called non-structural bonding. A structural bond is a bond that is subject to load. Non-structural bonding is a process that uses organic chemical adhesives to repair, fill, strengthen, and fix stone defects such as cracks, cracks, holes, and trachoma decoration positioning. [0003] Filling bonding (non-structural bonding) and structural bonding are obviously different in force, that is, filling bonding does not bear the load of force. The so-called filling has a great effect on beautifying the visual beauty of the stone a...
