Abstract

The invention discloses a demolding coating for building formworks, which is applied to the surface of a building formwork to arrive at corrosion resistance and self-demolding. The demolding coating comprises, by mass, 100 parts of thermosetting resin and a curing agent, 1-300 parts of graphite, and preferably further comprises 0.01-30 parts of a coupling agent, and 0.1-100 parts of aids. Preparation and application methods include: using the coupling agent to treat graphite, mixing well all the components, applying the mixture evenly to the surface of the building formwork, and allowing solidifying. After being applied once, the demolding coating is reusable in self-demolding of building formworks and can be reused over 200 times; using a demolding agent is not required, so that process steps are fewer, and material and manpower cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of self-demoulding of building formwork, and in particular relates to a coating for building formwork that can be repeatedly self-demoulding without a mold release agent. Background technique [0002] In the field of construction, building formwork is widely used for concrete pouring. At present, aluminum membrane panels, steel formwork and wooden formwork are commonly used. However, these formworks are easy to bond with concrete when used directly, resulting in difficulty in demoulding or rough surfaces. [0003] The commonly used solution at present is to use liquid lubricant or surfactant as a release agent and apply it on the surface of the formwork to assist in release, but this method is for one-time use. Labor and time, as well as the cost of release agents, and the release agent remaining on the concrete surface will also affect the quality of future surface coatings. Because it is difficult to cont...
