Abstract
The invention discloses an acid and alkali-resistant polyurethane sealing strip. The acid and alkali-resistant polyurethane sealing strip comprises polyurethane resin, a medicament-resistant agent, a dispersant, a lubricant, a filler, a plasticizer and a coupling agent, wherein the medicament-resistant agent is polytetrafluoroethylene, the dispersant is hydroxypropyl methyl cellulose, the lubricant is high-purity oleamide, the filler is quartz powder, the plasticizer is pentaerythriol tetrabenzoate and the coupling agent is titanium bis (triethanolamine) diisopropoxide. The product is prepared by adopting six additives, namely the polyurethane resin, the medicament-resistant agent, the dispersant, the lubricant, the filler, the plasticizer and the coupling agent, and the prepared product has good acid and alkali resistance, stable quality and high strength, as well as low production cost and convenience in processing.
Description
Technical field
The present invention relates to sealing material, be specifically related to a kind of acid and alkali-resistance polyurethane weatherstrip.
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, but urethane resin itself is but easily corroded by acid-basicity product, in use easily causes damage, and work-ing life shortens greatly.And when adopting the urethane resin of large content to produce, cost is higher, and the performance of enterprises is lower.
Summary of the invention
A kind of urethane resin and drug-resistant agent, dispersion agent, lubricant, weighting agent, fluidizer and coupling agent six kinds of additives of adopting are the object of the present invention is to provide to obtain, obtained product resistance to acids and bases is good, steady quality, intensity are high, and production cost is low, acid and alkali-resistance polyurethane weatherstrip easy to process.
Technical scheme of the present invention is, a kind of acid and alkali-resistance polyurethane weatherstrip, comprise urethane resin, drug-resistant agent, dispersion agent, lubricant, weighting agent, fluidizer and coupling agent, described drug-resistant agent is tetrafluoroethylene, described dispersion agent is Vltra tears, described lubricant is high-purity amine hydroxybenzene, described weighting agent is silica powder, described fluidizer is pentaerythritol tetrabenzoate, described coupling agent is two (trolamine) metatitanic acid diisopropyl ester, shared by each composition of described acid and alkali-resistance polyurethane weatherstrip, weight percent is respectively: described urethane resin accounts for 75.1%-80.4%, described tetrafluoroethylene accounts for 4.2%-5.1%, described Vltra tears accounts for 0.8%-1.6%, described high-purity amine hydroxybenzene accounts for 1.7%-2.6%, described silica powder accounts for 7.9%-8.8%, described pentaerythritol tetrabenzoate accounts for 3.6%-4.5%, described two (trolamine) metatitanic acid diisopropyl ester accounts for 1.4%-2.3%.
In a preferred embodiment of the present invention, shared by each composition of described acid and alkali-resistance polyurethane weatherstrip, weight percent is specially: described urethane resin accounts for 79.7%, described tetrafluoroethylene accounts for 4.3%, described Vltra tears accounts for 0.9%, described high-purity amine hydroxybenzene accounts for 1.8%, described silica powder accounts for 8.1%, and described pentaerythritol tetrabenzoate accounts for 3.7%, and described two (trolamine) metatitanic acid diisopropyl ester accounts for 1.5%.
In a preferred embodiment of the present invention, shared by each composition of described acid and alkali-resistance polyurethane weatherstrip, weight percent is specially: described urethane resin accounts for 75.8%, described tetrafluoroethylene accounts for 4.9%, described Vltra tears accounts for 1.5%, described high-purity amine hydroxybenzene accounts for 2.5%, described silica powder accounts for 8.7%, and described pentaerythritol tetrabenzoate accounts for 4.4%, and described two (trolamine) metatitanic acid diisopropyl ester accounts for 2.2%.
Of the present invention is a kind of acid and alkali-resistance polyurethane weatherstrip, this product adopts urethane resin and drug-resistant agent, dispersion agent, lubricant, weighting agent, fluidizer and coupling agent six kinds of additives to obtain, obtained product resistance to acids and bases is good, steady quality, intensity are high, and production cost is low, easy to process.
