The invention relates to the technical field of building
thermal insulation materials and particularly relates to a composite non-dismantling formwork with an integrated
thermal insulation structure and a preparation method thereof. The composite non-dismantling formwork comprises a mould pressing inorganic
adhesive benzene particle insulation board, an extruded sheet, an inner
protection layer, an outer
protection layer and a binder, wherein the mould pressing inorganic
adhesive benzene particle heat preservation plate and the
cement-based cloth are bonded to two sides of the extruded sheet through a binder, a steel
wire mesh is arranged between a
cement-based backing and the extruded sheet to form an inner
protection layer, and the
polymer mortar with the built-in
glass fiber gridding cloth is laid on the other side of the mould pressing inorganic
adhesive benzene particle heat preservation plate to form an outer protection layer; and after maintenance, the composite non-dismantling formwork with the integrated heat preservation structure is manufactured through
cutting. According to the composite non-dismantling formwork, the composite non-dismantling formwork is high in strength, good in fireproof performance and excellent in thermal performance, streamlined production is achieved, maintenance links are reduced, productivity is improved, equipment investment is reduced, the
plant site use amount is reduced, and the market
advantage is obvious.
