Description

A kind of PVC building templates and its formula, preparation method
Technical field
The present invention designs a kind of building template, and in particular to a kind of PVC building templates and its formula, preparation method.
Background technology
In the constructions such as house construction, bridge, tunnel construction and brick production, concrete pouring technology is often applied, is mixed Solidifying soil casting process needs template.Conventional template includes plank and steel plate, due to plank resource scarcity, steel plate again it is too heavy, now by Gradually use synthesis building template instead.Now synthesis building template wherein there are commonly wood plastic building mould, wood plastic building mould be by The regenerated particles such as waste plastics PP, ABS, PVC reclaimed materials, PE form, and the inside is given birth to mixed with wood powder or plant rod powder for filler material Production forms (black), and disadvantage is：Under the sun be heated can deform, subzero nail one nail can occur cracking, when high-altitude is dropped When easily rupturable, winter cannot construct；Another kind is mountain flour plastic building template.Mountain flour plastic building template be by waste plastics PP, The regenerated particles such as ABS, PVC reclaimed materials, PE form, and the inside filler is mountain flour, the shortcomings that plate equally exist under the sun by Thermal deformation, the nail of subzero nail one can crack, easily rupturable, winter is dropped in high-altitude to construct.Currently, synthesis building template is most Big drawback is that thermal stability is bad, and wave-like occurs in template face when the temperature is excessively high, and the number of turnover is few.Above two synthesis simultaneously Building template spells that mould is inconvenient, and loss is big there is also specification is few, and surface is easy viscous concrete, and when use needs brush releasing agent, Demoulding trouble；Meeting water template will appear lamination simultaneously, and fritter can only be used assembled, time-consuming；The useless template of fritter is without profit It is not recyclable with value.
In the building template that a variety of materials make, the advantage of plastic formwork more, recyclable reconstruction with its number of turnover, by Step replaces pervious wooden, bamboo matter and steel template, becomes the trend of building template future development.Plastic formwork intensity height, work Skill is simple, good economy performance, demoulding is easy, plasticity is good, will have wide practical use in construction market, its use can significantly Ground reduces building cost, accelerates speed of application, improves construction quality.Due to its high recycling rate, use will be state Family and society save vast resources.Simultaneously because the technology for producing plastic formwork with waste plastic has large-scale popularization and uses Possibility, therefore the application of plastic formwork will bring a change to construction industry.
There are complex process, building templates of high cost, obtaining to hold for existing PVC reclaimed materials building template formula and technique Yielding, the shortcomings of service life is short, prepared the thermo-labile of PVC reclaimed materials template products, anti-impact are poor.
For some problems that above-mentioned template is brought as building template, during number of patent application is 201110307112.8 State's invention patent discloses a kind of panel and preparation method thereof of combined type PVC reclaimed materials building templates, is mainly returned using PVC Rewinding resin SG-5 is major ingredient, using calcium zinc stabilizer, light caco3, Du Pont's titanium dioxide, impact modifier, UV Absorption Agent, reinforcing agent be auxiliary material, above-mentioned major ingredient is blended with auxiliary material, extrusioning shaping, traction, product cut.Although the invention improves The security performance of building, good seismic performance, while the secondary painting paint of workshop metope is eliminated, it is environment friendly and pollution-free.But The shock resistance and Vicat softening point of such building template are poor.
The Chinese invention patent of application number 201310356922.1 proposes to increase PVC recycling with alkali-free milled glass fiber Expect the method for heat resistance and impact strength, but overall cost is slightly higher.
In 103602008 B of Chinese invention patent CN, core is made in proposition -- and shell structure impact modifier, obtained highly resistance are leapt high Toughness PVC building templates.
