Abstract
The invention relates to a tunnel fire prevention pigment which comprises the following ingredients in parts by weight: 10-13 parts of expanded vermiculite, 15-18 parts of hydroxymethyl cellulose, 30-40 parts of styrene-acrylic emulsion, 12-15 parts of hydrochloric acid, 3-7 parts of zinc acetate, 6-12 parts of lime acetate, 2-5 parts of nano titanium dioxide, 11-16 parts of hexamethyl cellulose, 25-35 parts of sulphate aluminium cement and 4-7 parts of auxiliary agent. The tunnel fire prevention pigment is nontoxic and smoke-free, meets an environmental requirement, has the characteristics of good water resistance and low cost, and overcomes the defect that the existing tunnel fire prevention pigment is low in fire endurance.
Description
technical field [0001] The invention relates to a fireproof pigment, in particular to a tunnel fireproof coating. Background technique [0002] With the rapid development of my country's road traffic construction, highways, railways, subways and urban cross-street tunnels have developed rapidly. In addition, tunnels are also important channels for optical cables, oil transportation and water supply. Therefore, once a fire occurs in the tunnel, it will often cause heavy losses. Therefore, it is imperative to strengthen tunnel fire protection, and doing a good job in tunnel fire protection has obvious social and economic significance for traffic safety. At present, the building materials of tunnels have low fire resistance limit and are prone to fire. Contents of the invention [0003] The object of the present invention is to provide a kind of pigment, more specifically a kind of tunnel fire-proof pigment with high fire-resistance limit and not prone to fire. [0004] In o...
