Problems solved by technology

However, the plastic formwork used in the construction field is not easy to use solid formwork due to reasons such as heavy weight, high cost, and deformation. Hollow plastic building formwork has the advantages of light weight and high flatness, but its strength is not high enough to be impacted. Easy to deform, not stable enough
During use, due to damage to a certain part, it is easy to cause heavy substances such as mortar and sand to invade the cavity and increase the weight of the template, which brings great trouble to normal use. Part of the damage and the entire template scrapped
At the same time, the existing building templates still have a short service life, and the products cannot be recycled and reused after use, causing environmental pollution

Abstract

The invention discloses preparation of a high-molecular construction formwork material. The material is prepared by the following components: isotactic polypropylene, polyvinyl chloride, a reinforcing agent, a stabilizing agent, a foaming agent, an anti-oxidant, stearic acid, and a plasticizer. The invention discloses an application of the construction formwork. The construction formwork comprises a plate body, the thickness of the plate body is 10-25mm, and the plate body has a hollow structure; the plate body is internally provided with a primary support, and the primary support is in sawtooth shaped; one side of the plate body is provided with holes, diameters of the holes are 0.6-1.5cm, and the intervals between holes are 10-30cm; ribs are arranged at the side of the holes, the spaces between the ribs are 20-50cm, the ribs can effectively prevent deformation of the plate body, and the ribs have hollow structures; the ribs are internally provided with secondary supports, and the secondary supports are in V shaped. The high-molecular construction formwork material has the advantages of energy saving and environmental protection, complete recovery and utilization, resource saving, multiple usage frequencies, and long usage period; and construction formwork prepared by the material has the advantages of simple structure, easy splicing, and good resistance to impact.

Description

technical field [0001] The invention belongs to the field of building formwork production, and in particular relates to a preparation method and application of a polymer building formwork material. Background technique [0002] In the field of construction, people have been relentlessly pursuing and researching a simple, handy, lightweight, low-cost, economical and durable building formwork or composite formwork. The bamboo, wood or steel formwork used in the early days was almost eliminated due to reasons such as excessive weight or corrosion resistance, and the existing building formwork is more common with plastic building formwork. However, the plastic formwork used in the construction field is not easy to use solid formwork due to heavy weight, high cost, and deformation. Hollow plastic building formwork has the advantages of light weight and high flatness, but its strength is not high enough to be impacted. Easy to deform, not stable enough. During use, due to a cert...
