Stone back mesh glue

Abstract

The invention relates to stone back mesh glue which is prepared from the following steps of: heating up 450-470 parts by weight of pure water to 90 DEG C and adding the heated pure water into a reaction kettle; adding 110-120 parts by weight of protective colloid FRC (Fire Resistant Viscose Fiber) 678 into the reaction kettle; adding 180-200 parts by weight of methyl methacrylate MMA, 180-200 parts by weight of acrylic acid-2-ethyl hexyl ester 2EHA (Ethylhexyl Acrylate), 3.0-5.0 parts by weight of dipropylene glycol methyl ether (DPM), 2.0-4.0 parts by weight of ammonium persulphate APS, 0.3-1.0 part by weight of ammonia water, 2.0-4.0 parts by weight of preservative GXL, and 0.20-0.95 part by weight of wetting agent X-405 into a single slot for uniformly mixing and stirring. The invention provides the stone back mesh glue which is capable of greatly lowering the pollution to environment, reducing the occurrence of safety accidents and free of damages to the body of a worker.

Description

technical field [0001] The invention relates to a stone back mesh adhesive. Background technique [0002] Fujian Shuitou in my country is the largest stone processing base in the world. Stones mined in many countries are shipped here to be processed and then sold to all over the world. After investigation, there are more than 1,700 large and small stone processing factories here. They cut stones into thin slices and then A piece of glass fiber mesh is glued on one side of the stone so that the reinforced stone is not easy to be damaged. The amount of glue used per day is several hundred tons. In this field, unsaturated resin is used for bonding, which belongs to solvent-based resin. Since solvent-based glue has a large amount of VOC emissions, it causes large-scale air pollution. Most of the volatiles of solvent-based glue also contain strong carcinogens. Therefore, The body of the workers will be greatly injured, and the workers in this position can only work for 2 years be...

Problems solved by technology

In this field, unsaturated resin is used for bonding, which belongs to solvent-based resin. Since solvent-based glue has a large amount of VOC emissions, it causes large-scale air pollution. Most of the volatiles of solvent-based glue also contain strong carcinogens. Therefore, The body of the workers will be greatly injured. The workers in this position can only work for 2 years before they have to adjust their positions.
