Embodiment 1

[0089] Prepare 100kg of diluent for treating the fireproof insulation board: add 12kg of component A (12% by weight), 84kg of water (84% by weight), and 4kg of component B (4% by weight). Wherein component A includes 70 parts by weight of phenolic resin and 30 parts by weight of water; component B includes 91 parts by weight of water and 9 parts by weight of water repellent.

[0090] The method of use is:

[0091] With glue:

[0092]Add the two-component glue and water into the reaction kettle in proportion, and stir evenly.

[0093] Dipping:

[0094] Pour the evenly stirred dipping glue into the dipping tank, and the fiber needled felt enters the dipping pool driven by the roller to dip into the glue. With the decline of the liquid level in the dipping tank, the newly prepared dipping glue will be continuously replenished to ensure the stable progress of the dipping process.

[0095] Squeeze dry:

[0096] After being dipped in glue, squeeze out the excess glue in the fib...

Embodiment 2

[0105] Prepare 100kg of diluent for treating the fireproof insulation board: add 3kg of component A (3% by weight), 96.5kg of water (96.5% by weight), and 0.5kg of component B (0.5% by weight). Wherein A component comprises the phenolic resin of 70 weight parts, the water of 26 weight parts, the catalyst of 4 weight parts; The B component comprises the water of 50 weight parts, the catalyst of 9 weight parts, the inorganic binder of 9 weight parts, A chelating agent and a carbonizing agent in parts by weight, a flame suppressant in 9 parts by weight, a smoke suppressor in 6 parts by weight, and a waterproofing agent in 9 parts by weight.

[0106] Compared with the examples, this example adds catalysts, inorganic binders, chelating agents, carbonizing agents, smoke suppressants, and flame suppressants to the formula to ensure the high strength, low water absorption, and short afterburning of the fireproof insulation board. On the basis of this, the production and transportation...

Embodiment 3

[0110] Prepare 100kg of diluent for treating the fireproof insulation board: add 3kg of component A (3% by weight), 96.5kg of water (96.5% by weight), and 0.5kg of component B (0.5% by weight). Wherein A component comprises the phenolic resin of 70 weight parts, the water of 20 weight parts, the stabilizer of 5 weight parts, the catalyst of 5 weight parts; B component comprises the water of 50 weight parts, the catalyst of 9 weight parts, the catalyst of 9 weight parts Inorganic binder, 8 parts by weight of chelating agent and charring agent, 9 parts by weight of flame suppressant, 6 parts by weight of smoke suppressant, and 9 parts by weight of waterproofing agent.

[0111] In this example, a stabilizer is added on the basis of Example 2. On the basis of ensuring the high strength, low water absorption, short afterburn, and low cost of the fireproof insulation board, the storage and service life of the impregnated glue are greatly extended by adding the stabilizer .

Abstract

A composite impregnating adhesive for making a fireproof heat insulation plate comprises a phenolic resin, a flame inhibitor, a smoke inhibitor, a chelating agent, a charring agent, an inorganic adhesive, a waterproof agent, a catalyst and a stabilizing agent, wherein the phenolic resin is a primary adhesive. The aqueous impregnating adhesive is prepared through adding water and adopting a normal temperature mixing stirring process. Water is added as needed in the use process to dilute and adjust the concentration. The composite impregnating adhesive has the characteristics of no use of organic solvents bringing dangers and pollution, use convenience, simple control of the production process, less discharge of pollutants, and low cost. Compared with coats of other resin based impregnating adhesives, a coat of the composite impregnating adhesive, formed on the surfaces of fibers, has the advantages of protruding high temperature and burning resistances, almost no combustion or smoke at a high temperature, and low heat conductivity; and the fireproof heat insulation plate made through adopting the composite impregnating adhesive has a protruding fireproof heat insulation performance reaching an A1-level fireproof standard. The composite impregnating adhesive can be used for processing basalt fibers, and can also be used for processing various organic and inorganic fibers comprising rock wool, glass fibers, carbon fibers, stainless steel fibers, aramid fibers terylene and the like.

Description

technical field [0001] The invention relates to an impregnating glue, in particular to a composite impregnating glue for preparing a fireproof heat preservation board and a method for using the impregnating glue. Background technique [0002] Problems in the past Class A non-combustible insulation materials: [0003] (1) Polyurethane foam material [0004] The oxygen index of polyurethane is only 26, even B2 class fireproof (O 2 Index ≥ 27) can not reach, even easy to cause fire hazards in the construction site; in addition, it belongs to the foam closed cell system, coupled with the overall spraying construction on site, will inevitably bring obstacles to the evaporation of water vapor in the new wall in the future , resulting in a series of problems such as bulging, cracking, and leakage; moreover, for buildings, it is necessary to reserve pipe holes through the wall, air-conditioning holes, etc. Moreover, the polyurethane system needs to rely on the interface agent to ...
