Embodiment 1

[0010] An environmentally friendly fireproof coating for tunnels is prepared by mixing the following raw materials according to the weight ratio: 30-35 parts of refractory cement, 30-35 parts of sulphoaluminate cement, 30-35 parts of AEC expansion cement, 30-35 parts of urea-formaldehyde resin, 10-16 parts of soybean oil fatty acid alkyd resin, 5-9 parts of magnesium hydroxide, 5-9 parts of aluminum hydroxide, 10-15 parts of sepiolite, 5-9 parts of perlite, 10-15 parts of ethyl cellulose, 6-10 parts of glass fiber, 8-11 parts of aluminum silicate fiber, 5-7 parts of glass hollow floating beads, 4-8 parts of kaolin, 7-9 parts of vermiculite, and 4-8 parts of ammonium dichromate.

Embodiment 2

[0012] An environmentally friendly fireproof coating for tunnels is prepared by mixing the following raw materials according to the weight ratio: 30-35 parts of refractory cement, 30-35 parts of sulphoaluminate cement, 30-35 parts of AEC expansion cement, 30-35 parts of urea-formaldehyde resin, 10-16 parts of soybean oil fatty acid alkyd resin, 5-9 parts of magnesium hydroxide, 5-9 parts of aluminum hydroxide, 10-15 parts of sepiolite, 5-9 parts of perlite, 10-15 parts of ethyl cellulose, 6-10 parts of glass fiber, 8-11 parts of aluminum silicate fiber, 5-7 parts of glass hollow floating beads, 4-8 parts of kaolin, 7-9 parts of vermiculite, 4-8 parts of ammonium dichromate and 5-7 parts ammonium borate.

Embodiment 3

[0014] The formulations of the above examples are all prepared and constructed according to the following methods: (1) Ingredients, mix the paint and water at a ratio of about 0.7, first add a small amount of water while stirring while adding the paint, and add water in an appropriate amount, and generally stir for 20 minutes to form a thick paste Slurry (2) construction, use a sprayer to spray from the waist of the tunnel from bottom to top, each spraying is 3-7mm thick, and the construction interval is based on the fact that the last paint is basically dry, and so on, until the design thickness is sprayed, After the last spraying, if it needs to be smoothed, use the method of wiping and smoothing.

[0015] The finished products prepared in the above examples can all reach the following technical indicators after testing: 1. Sieve rate ≤ 1.0%; 2. Dry density ≤ 580kg / m 3 ;3. Water resistance: h≥24, the coating will not crack, peel off or fall off; 4. Alkali resistance: h≥24, t...

Abstract

A disclosed tunnel environment-friendly fireproof paint is mainly prepared by stirring the following raw materials in parts by weight: 30-35 parts of refractory cement, 30-35 parts of sulphoaluminate cement, 30-35 parts of AEC expansive cement, 30-35 parts of urea-formaldehyde resin, 10-16 parts of soybean oil fatty acid alkyd resin, 5-9 parts of magnesium hydroxide, 5-9 parts of aluminium hydroxide, 10-15 parts of meerschaum, 5-9 parts of perlite, 10-15 parts of ethyl cellulose, 6-10 parts of glass fiber, 8-11 parts of alumina silicate fiber, 5-7 parts of glass hollow floating beads, 4-8 parts of kaoline, 7-9 parts of vermiculite and 4-8 parts of ammonium bichromate. The paint provided by the invention is excellent in fireproof performance, corrosion resistance and stability, high in bonding strength, safe, nontoxic, short in curing time, convenient to construct and high in efficiency.

Description

technical field [0001] The invention relates to an environment-friendly fireproof coating for tunnels, belonging to the technical field of chemical coatings. technical background [0002] In architecture, the cross-sectional area exceeds 30m 2 The underground artificially constructed passage is defined as a tunnel. Tunnels not only undertake the task of transportation, but also function as channels for optical cables, cables, and even oil and water pipelines. Although the reinforced concrete components used as the main building in the tunnel are non-combustible materials, the tunnel fire has the characteristics of a rapid rise in ambient temperature after combustion, a long duration, a large fire range, and difficulties in fire fighting and entry. In a short period of time after the fire broke out, the local temperature of the fire site in the tunnel will rise rapidly to 1000°C. As the temperature continues to rise, the bound water in the concrete will turn into steam and ...
