Abstract

The invention provides a segmental type environmental protection fireproof paint used for tunnel, wherein the paint comprises separately packaged base-material and dispersing agent, on the construction site the proportion is water : base-material : dispersion agent = 100-120 : 100 : 1-3.

Description

technical field [0001] The invention relates to a tunnel fireproof coating in the technical field of fire protection. Background technique [0002] Tunnels are not only passages for transportation, but also passages for optical cables, cables, and even oil and water pipes. Therefore, among various vehicle accidents, tunnel fire accidents are the most difficult to rescue, the longest time to stop driving, and the largest economic losses. In order to improve the fire-resistant performance of tunnels, spraying fire-resistant coatings on the tunnel lining is one of the most widely used methods at present. Due to the humid environment of the tunnel, strong winds and vibrations will be generated in the tunnel when vehicles pass through. Therefore, the tunnel fireproof coating must not only have high fire resistance, strong adhesion and water resistance, but also require no toxic gas when the coating burns. produce. The inventor introduced such a tunnel fireproof coating in the f...
