Abstract
The invention discloses a durable polyurethane sealant which is prepared from polyurethane resin, a thickener, a wear-resistant agent, a scratch-proof agent, a lubricant, a cross-linking agent and a weather-resistant agent, wherein the thickener is hydroxypropyl methyl cellulose; the wear-resistant agent is nitrile butadiene rubber; the scratch-proof agent is glass powder; the lubricant is oleamide; the cross-linking agent is divinyl benzene; and the weather-resistant agent is 2-hydroxy-4-octyloxybenzophenone. The product, which is prepared from six additives, namely the polyurethane resin, the thickener, the wear-resistant agent, the scratch-proof agent, the lubricant, the cross-linking agent and the weather-resistant agent, is stable in quality, wear-resistant, scratch-proof, high in strength and good in weather resistance.
Description
Technical field
The present invention relates to sealing material, be specifically related to a kind of durable 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, but urethane itself is owing to existing the large problem of internal stress in process for processing, make quality product relatively unstable, easily occurs in use damaging.Although and the intensity in urethane resin surface own is comparatively strong, not wear-resisting, is easily scratched, makes the result of use of product poor.Rubber also also exists not ageing-resistant defect, and urethane resin exists equally.
Summary of the invention
The object of the present invention is to provide a kind of urethane resin and thickening material, anti-wear agent, anti-scratch agent, lubricant, linking agent and weather resisting agent six kinds of additives of adopting to obtain, obtained constant product quality, wear-resistant, scratch, intensity are high, the durable polyurethane seal gum of good weatherability.
Technical scheme of the present invention is, a kind of durable polyurethane seal gum, comprise urethane resin, thickening material, anti-wear agent, anti-scratch agent, lubricant, linking agent and weather resisting agent, described thickening material is Vltra tears, described anti-wear agent is liquid acrylonitrile butadiene rubber, described anti-scratch agent is glass powder, described lubricant is oleylamide, described linking agent is Vinylstyrene, described weather resisting agent is Octabenzone, shared by each composition of described durable polyurethane seal gum, weight percent is respectively: described urethane resin accounts for 81.9%-87.3%, described Vltra tears accounts for 2.4%-3.3%, described liquid acrylonitrile butadiene rubber accounts for 2.7%-3.6%, described glass powder accounts for 4.9%-5.8%, described oleylamide accounts for 0.6%-1.5%, described Vinylstyrene accounts for 1.3%-2.2%, described Octabenzone accounts for 0.8%-1.7%.
In a preferred embodiment of the present invention, shared by each composition of described durable polyurethane seal gum, weight percent is specially: described urethane resin accounts for 86.6%, described Vltra tears accounts for 2.5%, described liquid acrylonitrile butadiene rubber accounts for 2.8%, described glass powder accounts for 5.1%, described oleylamide accounts for 0.7%, and described Vinylstyrene accounts for 1.4%, and described Octabenzone accounts for 0.9%.
In a preferred embodiment of the present invention, shared by each composition of described durable polyurethane seal gum, weight percent is specially: described urethane resin accounts for 82.5%, described Vltra tears accounts for 3.2%, described liquid acrylonitrile butadiene rubber accounts for 3.5%, described glass powder accounts for 5.7%, described oleylamide accounts for 1.4%, and described Vinylstyrene accounts for 2.1%, and described Octabenzone accounts for 1.6%.
Of the present invention is a kind of durable polyurethane seal gum, this product adopts urethane resin and thickening material, anti-wear agent, anti-scratch agent, lubricant, linking agent and weather resisting agent six kinds of additives to obtain, and obtained constant product quality, wear-resistant, scratch, intensity are high, good weatherability.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of durable polyurethane seal gum, comprise urethane resin, thickening material, anti-wear agent, anti-scratch agent, lubricant, linking agent and weather resisting agent, described thickening material is Vltra tears, described anti-wear agent is liquid acrylonitrile butadiene rubber, described anti-scratch agent is glass powder, described lubricant is oleylamide, described linking agent is Vinylstyrene, described weather resisting agent is Octabenzone, shared by each composition of described durable polyurethane seal gum, weight percent is respectively: described urethane resin accounts for 81.9%-87.3%, described Vltra tears accounts for 2.4%-3.3%, described liquid acrylonitrile butadiene rubber accounts for 2.7%-3.6%, described glass powder accounts for 4.9%-5.8%, described oleylamide accounts for 0.6%-1.5%, described Vinylstyrene accounts for 1.3%-2.2%, described Octabenzone accounts for 0.8%-1.7%.
Further, shared by each composition of described durable polyurethane seal gum, weight percent is specially: described urethane resin accounts for 86.6%, described Vltra tears accounts for 2.5%, described liquid acrylonitrile butadiene rubber accounts for 2.8%, described glass powder accounts for 5.1%, described oleylamide accounts for 0.7%, and described Vinylstyrene accounts for 1.4%, and described Octabenzone accounts for 0.9%.
Further, shared by each composition of described durable polyurethane seal gum, weight percent is specially: described urethane resin accounts for 82.5%, described Vltra tears accounts for 3.2%, described liquid acrylonitrile butadiene rubber accounts for 3.5%, described glass powder accounts for 5.7%, described oleylamide accounts for 1.4%, and described Vinylstyrene accounts for 2.1%, and described Octabenzone accounts for 1.6%.
Carry out proportioning by each composition Different Weight per-cent, the product performance height obtained is differed.
Durable polyurethane seal gum of the present invention is when producing, and by urethane resin is processed into molten state, the performance according to each additive is added before and after urethane resin melting, afterwards by injection moulding, forms durable polyurethane seal gum finished product.
