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 [0001] The invention relates to sealing materials, in particular to a flame-retardant polyurethane sealant. Background technique [0002] The sealing material refers to the material that can withstand the displacement of the joint to achieve the purpose of airtightness and watertightness and is embedded in the joint of the building, called the sealing material. Seal materials include metallic materials (aluminum, lead, indium, stainless steel, etc.), non-metallic materials (rubber, plastic, ceramics, graphite, etc.), composite materials (such as rubber-asbestos board, airgel felt-polyurethane), but The most used is rubber-like elastomer material. Most of the existing rubber sealants cannot have a high temperature resistance when used, and at the same time, it is very easy to catch fire when used in some flammable workplaces, which makes the rubber sealant damaged, and frequent replacement also increases Increased production costs, not conducive to the devel...
