Abstract
The invention discloses a flame retardant polyurethane sealant. The flame retardant polyurethane sealant comprises polyurethane resin, a flame retardant, a coupling agent, filler, a plasticizer and a dispersant, wherein the flame retardant is 2,2-bis(3,5-dibromo-4-hydroxyphenyl) propane; the coupling agent is di(octyl phenol polyoxyethylene ether) phosphide; the filler is silicon dioxide; the plasticizer is acetyl trioctyl citrate; the dispersant is polyethylene wax. The flame retardant polyurethane sealant is prepared from the polyurethane resin, the flame retardant, the coupling agent, the filler, the plasticizer and the dispersant; the prepared flame retardant polyurethane sealant is unlikely to combust, good in flame resistance, ageing-resistant, convenient to process, stable in quality and low in cost.
Description
Technical field
The present invention relates to sealing material, be specifically related to a kind of flame-retardant polyurethane sealant.
Background technology
Sealing material with regard to refer to can bear seam displacement to reach airtight, watertight object and the material embedded in building joint is called sealing material.Sealing member material has metallic substance (aluminium, lead, indium, stainless steel etc.), also have non-metallic material (rubber, plastics, pottery, graphite etc.), matrix material (as rubber-asbestos plate, aerogel blanket-urethane), but to use maximum be heat-resistant powder filler material.Existing rubber seal glue in use, mostly all can not have a higher resistance to elevated temperatures, use the as easy as rolling off a log situation occurring catching fire in some incendive workplaces simultaneously, rubber seal glue is damaged, and change frequently and also improve production cost, be unfavorable for the development of enterprise.
Summary of the invention
The object of the present invention is to provide a kind of urethane resin and fire retardant, coupling agent, weighting agent, softening agent and dispersion agent five kinds of additives of adopting to obtain, obtained product be nonflammable, good flame retardation effect, the flame-retardant polyurethane sealant that ageing-resistant, easy to process, steady quality, cost are low.
Technical scheme of the present invention is, a kind of flame-retardant polyurethane sealant, comprise urethane resin, fire retardant, coupling agent, weighting agent, softening agent and dispersion agent, described fire retardant is 2, 2-two (3, the bromo-4-hydroxyphenyl of 5-bis-) propane, described coupling agent is two (octyl phenol Soxylat A 25-7) phosphide, described weighting agent is silicon-dioxide, described softening agent is ATOC, described dispersion agent is polyethylene wax, shared by each composition of described flame-retardant polyurethane sealant, weight percent is respectively: described urethane resin accounts for 75.8%-80.3%, described 2, 2-two (3, the bromo-4-hydroxyphenyl of 5-bis-) propane accounts for 2.8%-3.7%, described two (octyl phenol Soxylat A 25-7) phosphide accounts for 4.3%-5.2%, described silicon-dioxide accounts for 8.5%-9.4%, described ATOC accounts for 1.4%-2.3%, described polyethylene wax accounts for 2.7%-3.6%.
In a preferred embodiment of the present invention, shared by each composition of described flame-retardant polyurethane sealant, weight percent is specially: described urethane resin accounts for 79.8%, described 2,2-two (3, the bromo-4-hydroxyphenyl of 5-bis-) propane accounts for 2.9%, and described two (octyl phenol Soxylat A 25-7) phosphide accounts for 4.4%, and described silicon-dioxide accounts for 8.6%, described ATOC accounts for 1.5%, and described polyethylene wax accounts for 2.8%.
In a preferred embodiment of the present invention, shared by each composition of described flame-retardant polyurethane sealant, weight percent is specially: described urethane resin accounts for 76.3%, described 2,2-two (3, the bromo-4-hydroxyphenyl of 5-bis-) propane accounts for 3.6%, and described two (octyl phenol Soxylat A 25-7) phosphide accounts for 5.1%, and described silicon-dioxide accounts for 9.3%, described ATOC accounts for 2.2%, and described polyethylene wax accounts for 3.5%.
Of the present invention is a kind of flame-retardant polyurethane sealant, this product adopts urethane resin and fire retardant, coupling agent, weighting agent, softening agent and dispersion agent five kinds of additives to obtain, and obtained product is nonflammable, good flame retardation effect, ageing-resistant, easy to process, steady quality, cost are low.
Embodiment
