Chemical test method for corrosion resistance of EPS board

The invention discloses a chemical test method for the corrosion resistance of an EPS board. To be specific, the method comprises the following steps: step one, taking samples and measuring the apparent density, heat conductivity coefficient and tensile strength in a direction perpendicular to the board plane; step two, extracting 12 sample boards randomly among each batch of boards and classifying the boards into four groups to carry out an experiment; and step three, step a, taking three test samples in a glass water tank and adding petroleum in the tank, carrying out immersion for 36 hours;step b, taking three test samples into a temperature and humidity adjusting box for storage for 36 hours; step c, taking three test samples in a chemical test box and introducing corrosive gas into the test box for storage for 36 hours; and step d, taking three test samples into a salt fog test box for storage for 36 hours. According to the invention, simulation of anti-corrosion-performance testing in different corrosio
