Description

technical field [0001] The invention relates to the technical field of laboratory materials, in particular to a high-temperature-resistant and corrosion-resistant modified epoxy resin laboratory table mat. Background technique [0002] The laboratory countertop mat is the most common and popular equipment in the laboratory. Since the staff who conduct experiments often complete various chemical or pharmaceutical experiments on the laboratory bench, a special proposal is made for the countertop mat on the workbench. Generally speaking, table mats are required to be resistant to chemical corrosion and high temperature. [0003] Epoxy resin has excellent chemical stability and mechanical properties, super corrosion resistance, excellent high temperature resistance, and is a commonly used material for laboratory table mats. With the development of society, people have put forward higher requirements for the performance of laboratory countertops. Although there are many kinds of...
