Description
Technical Field
The invention relates to a marble adhesive and a preparation method thereof, in particular to a high-toughness marble adhesive and a preparation method thereof.
Background
The marble glue is unsaturated resin glue, and is also called marble glue at home. The marble glue is suitable for bonding among various stones or repairing cracks and fracture marks on the surfaces of the stones, and is commonly used for repairing, bonding, positioning and filling joints of various stone paving projects and various stones. It is used for stone filling bonding, also called non-structural bonding. The non-structural bonding is a process for repairing, filling, reinforcing and fixing the defects of the stone, such as cracks, holes, sand holes, product defects, decoration positioning and the like, by using an organic chemical adhesive, relative to the structural bonding. The application of the marble adhesive is very wide, and at present, a plurality of manufacturers develop various series marble adhesive products in China.
The existing marble glue is generally composed of unsaturated polyester polyol, filler and a small amount of thixotropic agent hydrogenated castor oil, and marble, granite and stone are bonded by the viscosity of the unsaturated polyester polyol. However, the marble glue has no toughness and low strength, and because the ratio of the unsaturated polyester resin to the fixed curing agent is very different (usually 100:3), the marble glue is not easy to control during manual construction, once the ratio exceeds 3%, the marble glue becomes brittle, the bonding performance is reduced, the service life is finally shortened, and the danger is caused.
In view of the above, a marble adhesive with excellent mechanical properties is urgently needed to be found.
