Description
Technical field
The present invention relates to a kind of building water-proof material, particularly material modified with the waste polyethylene butyral is the waterproof roll of feedstock production, belongs to the construction engineering waterproof material technical field.
Background technology
Water-proof material is construction industry and other relevant needed critical function material of industry, and along with China's rapid economy development, fields such as building, bridge, tunnel, agricultural water conservancy and communications and transportation have all proposed many kinds, high-quality requirement to water-proof material.Water-proof material mainly comprises waterproof paint and waterproof roll, and waterproof roll can be divided into types such as asphalt felt, polyvinyl chloride (PVC), terpolymer EP rubber (EPDM), reclaimed rubber.Pitch class coiled material has temperature influence that the shortcoming short than large deformation, working life takes place, and waterproof roll elasticity such as PVC are low, and bending property is poor, the low temperature hardening, becomes fragile; EPDM based sheet cost is higher, and processing forming and construction viscosity etc. are not satisfactory; Though regenerated rubber waterproof sheet cost is lower slightly, its intensity, elongation, every poor-performing such as ageing-resistant all demonstrate its defective in using in a lot of fields.
Polyvinyl butyral acetal (poly (vinyl butyral), PVB) resin is typical polar material, not only nontoxic, tasteless, have good photostabilization, water tolerance, winter hardiness and shock resistance again, multiple materials such as glass, synthetic glass, metal, timber, pottery, leather, fiber are had good adhesiveproperties.Compare with the resin raw material of producing waterproof roll commonly used, PVB is many-sided not a halfpenny the worse in elasticity, intensity and ageing resistance etc.But PVB resin price costliness, produce waterproof roll and on price, do not have advantage fully, its main application be in laminated safety glass is made as the intermediate adhesion thin film layer, this shatter proof glass is widely used in fields such as automobile, train, Highrise buildings, aviation, navigation.
According to statistics, the year consumption of world PVB intermediate course is about 100,000,000 square metres.The automobile that the U.S. scraps every year has 1,200 ten thousand approximately, therefrom produces about 100,000 tons PVB waste material.About 3,000,000 of domestic annual abandoned car, only 30,000 tons of PVB waste materials of this annual generation.Simultaneously, the solar photovoltaic assembly encapsulation also needs the PVB intermediate coat with photovoltaic glass, and along with building is more and more to the use of photovoltaic glass, PVB waste material generation also will increase thereupon.Therefore, be that main raw material prepares waterproof roll and has important society and economic double meaning to reclaim waste PVB.Chinese invention patent 1958659A discloses " waterproofing material of polyvinyl butyral acetal ", Chinese invention patent 1911999A discloses " the synthetic roof of PVB formula material ", though the disclosed technical scheme of above-mentioned two pieces of patents has all adopted the polyvinyl butyral acetal raw material, but in the related technical scheme and not mentioned polyvinyl butyral acetal raw material in processing and the deficiency and the defective that exist in using, thereby these two pieces of patents do not propose to improve the polyvinyl butyral acetal raw material in processing and the deficiency that exists in using and the technical scheme of defective.
When processing or use, there are following three defectives in unmodified polyvinyl butyral acetal: there is the roll banding phenomenon in (1) polyvinyl butyral acetal in the course of processing as water-proof material.Polyvinyl butyral acetal is a kind of autohension material, various surfaces all had excellent adhesivity, this is the advantage of polyvinyl butyral acetal as water-proof material, but the also inferior position in its process for processing exactly, the autohension of polyvinyl butyral acetal causes occurring the roll banding phenomenon in the waterproofing material of polyvinyl butyral acetal production, causes process complications and difficultyization.(2) winter hardiness of polyvinyl butyral acetal has much room for improvement.The second-order transition temperature of polyvinyl butyral acetal is about 50 ℃, and the northern frore area polyvinyl butyral sheet becomes stiff in the winter time, is unfavorable for construction, and operating efficiency is reduced.(3) polyvinyl butyral acetal is stable to alkali and oxygenant, but is unsettled in acidic solution.Contain acetal radical on the polyvinyl butyral acetal macromolecular chain, acetal radical issues unboiled water at acidic conditions and separates, and the mechanical strength of polyvinyl butyral acetal is reduced, the range of application of reduction polyvinyl butyral waterproof coiled material.
Summary of the invention
For fear of with defective that overcomes prior art and deficiency, it is the water-proof material of main raw material preparation with the waste polyethylene butyral that reclaims that the object of the invention is to provide a kind of, make it have excellent processing characteristics and use properties, and can widen its use range, and production technique is simple, cost is low.
For realizing the object of the invention, modified waste polyvinyl butyral waterproof coiled material of the present invention is made by following composition of raw materials and production technique: to reclaim the waste polyethylene butyral is that main raw material, rubber or elastomerics are main auxiliary material, are equipped with auxiliary materials such as softening agent, release agent, stopping composition, by a certain percentage in Banbury mixer mixing after, the employing mill is plasticated into strips or slab-like enters the typing of macintoss screw extrusion molding machine, adopts the tri-roll press machine production line to obtain determining the coiled material of thickness again.
