Problems solved by technology

However, marble glue itself has no toughness and low strength, and because the ratio of unsaturated polyester resin to the fixed curing agent formula is very different (usually 100:3), it is difficult to control during manual construction. Once the ratio exceeds 3%, it will be damaged. It will cause the colloid to become brittle, reduce the bonding performance, and eventually shorten the life, resulting in danger. In addition, the filler used in the marble glue has a high o

Abstract

The invention provides high-toughness marble glue. The high-toughness marble glue is characterized by comprising the following components in parts by weight: 20-35 parts of unsaturated polyester resin, 3-6.5 parts of polyether acrylate, 0.01-0.1 part of nano core-shell rubber particles, 2-4.5 parts of trimethylol ethane triacrylate, 0.2-0.5 part of an unsaturated polyester resin initiator, 0.5-3 parts of a thixotropic agent and 35-55 parts of inorganic filler. The high-toughness marble glue has high bonding strength, high ageing resistance and stable weather ability, and meanwhile has high toughness and flexibility, deformation and warp to cause dropping of adhered plates due to vibration or under the effects of wind power and cold shrinkage and thermal expansion can be prevented, and thepreparation method is simple in process and facilitates construction.

Description

technical field [0001] The invention relates to a marble glue and a preparation method thereof, in particular to a high-toughness marble glue and a preparation method thereof. Background technique [0002] Marble glue is unsaturated resin glue, which is also called marble glue in China. Marble glue is suitable for bonding between various stone materials or repairing cracks and broken marks on the surface of stone materials. It is used for stone filling bonding, also known as non-structural bonding. Non-structural bonding is a process that uses organic chemical adhesives to repair, fill, strengthen, and fix stone defects such as cracks, holes, sand holes, product defects, and decoration positioning. The application of marble glue is very extensive. At present, many domestic manufacturers have developed various series of marble glue products. [0003] The existing marble glue is generally composed of unsaturated polypolyester, filler and a small amount of thixotropic agent ...
