The expansive fire-resisting paint contains the components of acrylic resin, catalyst, carbon-forming agent, foaming agent, fire-resisting agent, reinforcing agent, pigment filling material, adjuvant and smoke inhibiting agent, and is characterized by that it utilizes the modification of acrylic resin, surface treatment of catalyst and addition of smoke inhibiting agent to raise comprehensive property of paint. When the paint film is heated and expanded, it can be formed into fire-resistant carbonized layer with three-D space structure, and can release fire-resisting gas to prevent flame from spreading. Said paint is suitable for steel structure, and material and electric cable, etc.

The invention provides a hydrocarbon resistance fire-proof and explosion-proof coating which is prepared from, by weight, 20-60 parts of emulsion powder, 0-20 parts of polyvinyl alcohol, 1-3 parts of hydrogenated castor oil, 15-35 parts of polyvalent alcohol phosphate flame retardant, 5-13 parts of melamine cyanurate, 4-16 parts of zinc borate, 3-6 parts of modified expanded vermiculite and 0-2 parts of rutile type nanometer titania. The coating is high in hydrocarbon fire resistance limit, also has the explosion resistance, can adhere to a base material in the good condition after an explosion happens, enables a coating film to have the pressure relief function in the explosion, and is good in adhesion force, high in strength, capable of withstanding influences of high and low temperature cycling, good in water resistance, acid-base resistance, salt corrosion resistance and weather resistance, good in flexibility, not prone to disengagement, stable in storage, long in service life, environmentally friendly, convenient to construct, low in construction cost, simple in preparation technology and low in energy consumption. The hydrocarbon resistance fire-proof and explosion-proof coating is particularly suitable for being used as surface coatings of steel materials, aluminum materials and other materials in indoor and outdoor petrochemical industries.

The invention provides a water-based fireproof coating which is prepared from the following components in parts by weight: 40 parts of titanium dioxide powder, 40 parts of lithopone, 40 parts of silicon ash powder, 40 parts of ash calcium powder, 440 parts of water, 400 parts of silica sol, 60 parts of milk ester, 2 parts of fire retardant, 1 part of defoaming agent, 2.5 parts of multifunction additive and 1.5 parts of thickening agent. According to the water-based fireproof coating provided by the invention, the defects of the existing fireproof coating that the heat stability is poor and the phenomenon of the increasing of smoke generating quantity is caused due to a large quantity of organic resins existing in the existing fireproof coating are overcome. The water-based fireproof coating is good in fireproof and heat-insulating performance, good in bonding force and high in strength, and is not influenced by the cycling of high and low temperatures. A coating layer obtained by the water-based fireproof coating has the characteristics of being good in water resistance, acid resistance and salt corrosion resistance, difficult to fall off, stable to store, good in decoration, convenient to construct and the like; smoke is not generated or small amount of smoke is generated during the burning of the coating layer.

The invention relates to a raft foundation chilled water storage device. The raft foundation chilled water storage device comprises a plurality of building raft foundation trough bodies which are arranged adjacently. The side wall of each building raft foundation trough body is provided with water through holes, and chilled water is guided to flow among the raft foundation trough bodies through the water through holes. The raft foundation chilled water storage device has the advantages that a labyrinth cold accumulation mode is put forward, an underground raft foundation area is fully utilized for chilled water storage, the initial investment for a system is reduced, and the use space is saved; the operation possibility of a non-occupation type cold accumulation mode is reserved, when not ideal, the actual operation effect of the labyrinth chilled water storage mode can be switched to the non-occupation type cold accumulation mode for operation, and the performance reliability is improved; a heat preservation form of polyurethane on-site foaming is adopted in heat preservation of the raft foundation trough bodies, and the advantages of good heat preservation and insulation effects, good chemical stability and convenient construction are achieved; a polyurea waterproof system is adopted in the waterproof technology and has the advantages that solidification is quick, the construction efficiency is high, and the ageing-resistant performance, salt corrosion resistance, thermal stability, binding power and the like and good.
