The support apparatus includes: a suspension structure (1) configured to suspend a test unit (2); and a support structure disposed under the suspension structure (1) and configured to support the test unit (2). The suspension structure (1) and the support structure are matched to cause a stiffness of the support apparatus for a modal test to be zero. The support structure includes an anti-stiffness rhombus-shaped frame (4), a scalable sleeve, a horizontal elastic component (49), and a base (6). The scalable sleeve is connected to the anti-stiffness rhombus-shaped frame (4) and the base (6) respectively, and the horizontal elastic component (49) connects two diagonal points of the anti-stiffness rhombus-shaped frame (4).

Abstract: The present application discloses a fireproof coating material, and belongs to the technical field of fireproof coatings. The fireproof coating material includes 40-80 parts of an aqueous curing agent, 20-50 parts of water and 80-200 parts of a mother liquor of the fireproof coating material, wherein the mother liquor of the fireproof coating material consists of 50-80 parts of a flame retardant, 15-25 parts of a dispersant and 190-220 parts of water. The flame retardant used can not only effectively improve the problems of poor compatibility and mixing uniformity of a flame retardant with an aqueous latex in the existing fireproof coating material, but also can utilize O and H contained in a flame retardant system to form a carbonized layer during dehydration to isolate oxygen, preventing combustion, and enhancing the fire retardant performance.
