Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples, and the following examples are only used to illustrate the present invention rather than limit the present invention. Table 1 is an embodiment.

[0021] Table 1

[0022]

[0023] The manufacture method of above-mentioned each embodiment is identical, and its method is as follows:

[0024] 1. First, according to the dosage in Table 1, add expandable graphite, titanium dioxide, molybdate, zinc borate, etc. to component A of epoxy resin, disperse in a high-speed disperser for 10 minutes, transfer to a sand mill, and grind Until the coating fineness is 50u~80u, a part of the sample of solvent-free epoxy resin is made.

[0025] 2. Add melamine, pentaerythritol, and ammonium polyphosphate flame retardant to curing agent B component, disperse in a high-speed disperser for 10 minutes, transfer to a sand mill, grind until the coating fineness is 50u~80u, and make a non-toxic Anothe...

Abstract

The invention provides a solvent-free epoxy resin fire-resistant coating for an ultrathin steel structure, which comprises the following components in part by mass: 30 to 50 parts of solvent-free epoxy resin, 30 to 50 parts of inflame retarding system, 5 to 10 parts of titanium white, 5 to 8 parts of zinc borate, 1 to 3 parts of expanded graphite, 0.1 to 1 part of smoke inhibitor and 0.5 to 2.0 parts of various aids, wherein the inflame retarding system is a complex system of melamine, pentaerythritol and ammonium polyphosphate in a ratio of 1:3:2 or 1:3:1 or 2:3:1. The solvent-free epoxy resin fire-resistant coating has the advantages that: (1) the coating technology of solvent-free epoxy resin terrace is applied to the fire-resistant coating for the ultrathin steel structure, so that the fire-resistant coating for the ultrathin steel structure has the advantage of epoxy coatings and properties of fire prevention; (2) the fire-resistant coating for the ultrathin steel structure has the characteristic of environmental protection; (3) the coatings have high matching performance and can be better compatible with epoxy zinc-rich anticorrosion primers; and (4) the fire-resistant coating has high bonding strength which is more than or equal to 1.5 MPa, and has the characteristics of water prevention, corrosion prevention, high surface decoration and the like.

Description

technical field [0001] The invention relates to a solvent-free epoxy resin ultra-thin steel structure fireproof coating, in particular to a solvent-free epoxy resin ultra-thin steel structure fireproof coating which is directly sprayed. The solvent-free epoxy resin is different from the water-based epoxy resin resins and solvent-based epoxies. Background technique [0002] As a form of building structure, steel structure is widely used in the construction industry due to its high strength, light weight, good extensibility, earthquake resistance and short construction period. However, since the steel structure itself is non-combustible, the problem of fire protection and heat insulation protection of the steel structure was once ignored by people. According to relevant domestic and foreign reports and the tests and statistics of relevant institutions, the fire resistance of steel structure buildings is worse than that of masonry structures and reinforced concrete structures....
