Abstract
The invention discloses high-performance polyurethane sealant. The high-performance polyurethane sealant comprises polyurethane resin, a crosslinking agent, a solvent-resistant additive, a dispersing agent, a plasticizer, a filling agent and a coupling agent, wherein the crosslinking agent is waterborne epoxy resin, the solvent-resistant additive is polyvinylidene fluoride, the dispersing agent is oxidized polyethylene wax, the plasticizer is acetyl-tri-n-butyl citrate, the filling agent is talcum powder, and the coupling agent is aminopropyl triethoxy silane. The high-performance polyurethane sealant is obtained by adopting six additives, namely polyurethane resin, the crosslinking agent, the solvent-resistant additive, the dispersing agent, the plasticizer, the filling agent and the coupling agent, and the obtained high-performance polyurethane sealant is high in strength, good in solvent resistance, easy to process, low in cost, good in quality and long in service life.
Description
Technical field
The present invention relates to sealing material, be specifically related to a kind of high performance polyurethane seal gum.
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.Urethane resin is widely used as a kind of main sealing material starting material, urethane itself in use, product strength is general, solvent resistance is poor, and simultaneously in process of production owing to not easily processing, quality product is poor, the work-ing life of product is shortened, and product itself costly, involve great expense, cost is high.
Summary of the invention
The object of the present invention is to provide a kind of urethane resin and linking agent, solvent resistant additive, dispersion agent, softening agent, weighting agent and coupling agent six kinds of additives of adopting to obtain, obtained product strength is high, solvent resistance good, easy to process, cost is low, quality is good, the high performance polyurethane seal gum of long service life.
Technical scheme of the present invention is, a kind of high performance polyurethane seal gum, comprise urethane resin, linking agent, solvent resistant additive, dispersion agent, softening agent, weighting agent and coupling agent, described linking agent is aqueous epoxy resins, described solvent resistant additive is polyvinylidene difluoride (PVDF), described dispersion agent is oxidized polyethlene wax, described softening agent is ATBC, described weighting agent is talcum powder, described coupling agent is aminopropyl triethoxysilane, shared by each composition of described high performance polyurethane seal gum, weight percent is respectively: described urethane resin accounts for 81%-86.3%, described aqueous epoxy resins accounts for 1.8%-2.7%, described polyvinylidene difluoride (PVDF) accounts for 0.6%-1.5%, described oxidized polyethlene wax accounts for 1.1%-1.9%, described ATBC accounts for 2.4%-3.3%, described talcum powder accounts for 6.5%-7.4%, described aminopropyl triethoxysilane accounts for 1.3%-2.2%.
In a preferred embodiment of the present invention, shared by each composition of described high performance polyurethane seal gum, weight percent is specially: described urethane resin accounts for 85.7%, described aqueous epoxy resins accounts for 1.9%, described polyvinylidene difluoride (PVDF) accounts for 0.7%, described oxidized polyethlene wax accounts for 1.2%, described ATBC accounts for 2.5%, and described talcum powder accounts for 6.6%, and described aminopropyl triethoxysilane accounts for 1.4%.
In a preferred embodiment of the present invention, shared by each composition of described high performance polyurethane seal gum, weight percent is specially: described urethane resin accounts for 81.6%, described aqueous epoxy resins accounts for 2.6%, described polyvinylidene difluoride (PVDF) accounts for 1.4%, described oxidized polyethlene wax accounts for 1.8%, described ATBC accounts for 3.2%, and described talcum powder accounts for 7.3%, and described aminopropyl triethoxysilane accounts for 2.1%.
Of the present invention is a kind of high performance polyurethane seal gum, this product adopts urethane resin and linking agent, solvent resistant additive, dispersion agent, softening agent, weighting agent and coupling agent six kinds of additives to obtain, and obtained product strength is high, solvent resistance good, easy to process, cost is low, quality is good, long service life.
Embodiment
