Description
Technical field
The present invention relates to paint preparation fields, more specifically to a kind of guarantor's mould agent coating and preparation method thereof.
Background technique
In bridge, road and skyscraper building course, needs to build mold with plate, be then poured coagulation in a mold
Soil removes plate after concrete curing, reuses.It was in the past usually selection plank as mold material in work progress
Material, with people to the protection of forest, using the requirement of portability, beauty and durability, metal aluminium gradually instead of timber,
The advantages that as the preferred material of building mould, metal aluminium has a lightweight, easy moulding, can be recycled, but with also having and coagulation
The good disadvantage of native binding force is generally adopted by present to guarantee that mold can smoothly demould after concrete curing in aluminium
The method that mould release (silicone oil) is smeared on mould, silicone oil are easily mixed into mixed because not adhering to aluminium in casting process
Quality is influenced in solidifying soil, in addition silicone oil is coated mold before needing casting every time, and does what release agent was made with silicone oil
Cement surface has to the ability coating paint after sandblasting, increases the workload of execute-in-place worker.One can be developed
The material that kind repeatedly demoulds improves the quality of concrete, promotes the architectural appearances such as bridge, mentions for reducing labor intensity of workers
High efficiency of construction is all very helpful.
Through retrieving, Chinese Patent Application No.: 2016104409878, the applying date: on June 20th, 2016, innovation and creation name
