Rubber slab with anticorrosion lining special for sodium hypochlorite

Abstract

The invention provides a rubber slab with anticorrosion lining special for sodium hypochlorite, and main auxiliary raw materials comprises the following components by weight: 100 parts of butyl rubber, 30-40 parts of carbon black N774, 40-50 parts of carbon black N990, 3-8 parts of eleaostearic acids, 6-10 parts of polyethylene wax, 15-20 parts of barium sulfate, 4-8 parts of paraffin oil, 6-10 parts of rosin and 1-2 parts of promoter TT. The invention can effectively avoid running, emerging, dropping and leaking phenomenon in factory, and avoid generation of personal damage accidents, and reduce production cost with social benefits. The invention is especially suitable for storing sodium hypochlorite solution in the chemical production process and producing anticorrosion lining of reaction equipment.

Description

technical field [0001] The invention relates to an anti-corrosion rubber plate, in particular to an anti-corrosion lining rubber plate specially resistant to sodium hypochlorite. Background technique [0002] Sodium hypochlorite (NaClO) is weakly acidic. Due to the presence of chloride ions, general stainless steel materials are not resistant to its corrosion. Usually, storage and reaction will consider using titanium equipment, Teflon lining equipment, rubber lining equipment and FRP equipment, titanium equipment and The production of PTFE lining is expensive, and the investment cost is very high for users. Since FRP equipment is a non-metal container, it is not impact-resistant and difficult to repair once damaged, and its safety performance is poor. Compared with the above equipment, rubber-lined equipment It is the most economical and safest, but because sodium hypochlorite is a strong oxidant with strong oxidizing properties, rubber, as a polymer material, will age...

AI Technical Summary

Problems solved by technology

[0002] Sodium hypochlorite (NaClO) is weakly acidic. Due to the presence of chloride ions, general stainless steel materials are not resistant to its corrosion. Usually storage and reaction will consider using titanium equipment, Teflon lining equipment, rubber lining equipment and FRP equipment, titanium equipment and The production of PTFE lining is expensive, and the investment cost is very high for users. Since FRP equipment is a non-metal container, it is not impact-resistant and difficult to repair once damaged, and its safety performance is poor. Compared with the above equipment, rubber-lined equipment It is the most economical and safest, but because sodium hypochlorite is a strong oxidizing agent with strong oxidizing properties, rubber, as a polymer material, will age quickly in a strong oxidizing medium, directly affecting the service life, so The rubber sheet produced by the common formula is also very poor in its resistance
