Embodiment 1

[0053] A. Under the standard conditions stipulated in GB / T 9278-2008, paste cross-shaped copper strips on the A4 size non-asbestos fiber cement board (insulating substrate); use 150μm wet film preparation device for object 1 and object 2 respectively Three test panels were scraped on each of the long sides.

[0054] B. The test panel was dried naturally for 1 hour under standard conditions, baked at 50°C for 0.5 hour until it was completely dry, and tested the antistatic property according to the method specified in GB / T 1410-1989 after cooling. The results are shown in Table 3.

Embodiment 2

[0056] A. Under the standard conditions stipulated in GB / T 9278-2008, on the test panels of object 1 and object 2 in Example 1, object 3 and object 4 respectively use a 500 μm wet film preparation device to scrape 3 along the long side test board.

[0057] B. Dry the test panel under standard conditions for 0.5h, bake at 70°C for 1h until it is completely dry, and test the antistatic property according to the method specified in GB / T 1410-1989 after cooling. The results are shown in Table 3.

Abstract

The invention relates to a method for rapidly detecting the antistatic property of antistatic floor paint. The method comprises the following steps: testing an antistatic primer and testing an antistatic finish paint. By adopting the method for rapidly detecting the antistatic property of the antistatic floor paint, the antistatic property detection period of the antistatic floor paint can be shortened from 168 hours to about 2 hours, the combined test of the volume resistance and the surface resistance and the same-plate test of the primer and the finishing paint can be realized, and the factory inspection efficiency is obviously improved. Meanwhile, the detection method is similar to actual on-site construction, the anti-static property and the matching property of a factory product areensured to be consistent with those of a construction site, and system anti-static property disqualification caused by independent detection of primer or finish paint is prevented. According to the method for rapidly detecting the antistatic property of the antistatic floor paint, the surface resistance and the volume resistance are combined into one plate for testing, and the primer and the finish paint are tested on the same plate.

Description

technical field [0001] The invention relates to a method for quickly testing the antistatic property of an antistatic floor paint. Background technique [0002] Anti-static floor paint is a two-component coating composed of resin, pigments and fillers, conductive materials, diluents and additives, and a curing agent in a certain proportion. It has special anti-static functions and is suitable for electronics, communications, computers, and precision instruments. , powder, organic solvent, gas, gunpowder depot and other floor and wall coating systems that require antistatic places. Anti-static floor paint generally uses epoxy resin as the carrier, which has all the excellent properties of epoxy floor paint, can quickly discharge electrostatic charges, and has a long-lasting anti-static effect. At present, epoxy floor paints on the market are mainly solvent-based and solvent-free. With the increasingly stringent environmental protection requirements, water-based epoxy floor p...
