Abstract
The invention discloses an anti-seepage tunnel fireproof paint which is composed of high-temperature-resistant cement, encrypted silica fume, a flame retardant, fireproof filler, an anti-seepage agent, an antifreezing agent, a thixotropic agent and inorganic anti-cracking fibers, has good fireproof performance and an anti-seepage function, and makes up the defect of poor waterproof function of the traditional fireproof paint; the fireproof coating is free of asbestos, free of harmful gas generation at high temperature, green and environment-friendly, and suitable for the fields of traffic tunnels, civil air defence, underground buildings and the like.
Description
Technical field
What the present invention relates to is a kind of frie retardant coating, and particularly a kind of fire-proof coating for tunnels is exactly a kind of fire-proof coating for tunnels of antiseepage specifically.
Technical background
Frie retardant coating ensures one of product, the increasing building field that is applied to as building safety; In recent years, fire-proof coating for tunnels is also popularized in the use of field of traffic gradually, and under the prerequisite that satisfies the fire-proof coating for tunnels fundamental property, to further improving the fire-proof coating for tunnels performance, domestic have a multinomial patent achievement.For example CN101353489 Cai Wei waits the environment friendly acoustical absorption frie retardant coating of people's invention clearly, is made up of refractory cements, perlite, vermiculite, lime carbonate or talcum powder, strong TKK 021; The nano inorganic expansion type tunnel fire-proof paint of people such as CN101343430 Xu Zhi victory research and development improves the function of fire-proof coating for tunnels through adding swelling agent and nano titanium oxide.
Above-mentioned technology has increased the function of fire-proof coating for tunnels, has improved the added value of fire-proof coating for tunnels, and right existence self water-intake rate is higher, the deficiency of not antiseepage but appoint.
Summary of the invention
The objective of the invention is to provide a kind of fire-proof coating for tunnels of antiseepage; Reach GA98-2005 " the concrete structure frie retardant coating is " in the requirement satisfying product; The water-intake rate of product own is very low, can also prevent the outside seepage of moisture of basic unit, can reduce even replace the water-proof material of basic unit; Reduce construction costs, shorten the engineering construction cycle.
For addressing the above problem, the present invention is achieved in that
A kind of fire-proof coating for tunnels of antiseepage, by ordinary method preparation, it comprises high temperature resistant cement, encrypts SILICA FUME, fire retardant, fire-proof packing, permeability-reducing admixture, frostproofer, thixotropic agent, inorganic cracking resistance are fibrous.The fire-proof coating for tunnels that it is characterized in that antiseepage is formulated by following substances in percentage by weight:
High temperature resistant cement 25-40%
Encrypt SILICA FUME 8-15%
Fire retardant 1-5%
Fire-proof packing 40-60%
