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.

Embodiment 1

[0022] Stone back net glue of the present invention, it adopts following steps to make:

[0023] 1) Heating 450-470 parts by weight of pure water to 90°C and adding it to the reactor, then adding 110-120 parts by weight of protective colloid acrylic resin FRC678 to the reactor, and keeping it warm for 3 hours;

[0024] 2) Methyl methacrylate MMA with parts by weight of 180-200, parts by weight of 2-ethylhexyl acrylate 2EHA, parts by weight of dipropylene glycol methyl ether DPM with parts by weight of 3.0-5.0, parts by weight of 2.0-4.0 ammonium persulfate APS, 0.3-1.0 parts by weight of ammonia water with an ammonia content of 25% to 28% (percentage by weight), 2.0-4.0 parts by weight of preservative GXL, 0.20-0.95 parts by weight of Add wetting agent X-405 into the monomer tank and mix evenly for pre-emulsification;

[0025] 3) When the temperature of the material in the reactor drops to 80°C—90°C, evenly add the pre-emulsified monomer in step 2 into the reactor, and the dr...

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...
