The invention discloses a preparation method of a high-strength building plastic formwork with strong nail-holding power, and belongs to the technical field of
high polymer materials. The prepared formwork has strong nail-holding power, is flat and smooth, the formwork is tightly and smoothly spliced, the surface degree and the finish degree of a concrete structure after demolding exceed the technical requirements of an existing fair-faced formwork, secondary plastering is not needed, labor and materials are saved, and the formwork is light in weight and easy to install. The formwork is lightin weight and high in process adaptability, can be sawn, planed, drilled and nailed, can be randomly formed into any geometrical shape, meets the requirements of building formworks in various shapes,and is simple and convenient to demould. Concrete does not stick to the plate surface, a
release agent is not needed, demolding and ash removal are easy, and the stability and
weather resistance are achieved. The formwork is high in
mechanical strength, under the temperature condition of 20-60 DEG C, low in shrinkage, free of wet expansion,
cracking and deformation, stable in size, resistant to alkali,
corrosion,
flame, water and mice, resistant to insects, beneficial to maintenance, free of water absorption, high in turnover frequency, not less than 100 times of repeated use of nails and lowin use cost.
