Description
Technical field
The present invention relates to building materials field, in particular to a kind of manufacture method of form for construction engineering.
Background technology
At present, building template used in architectural engineering is mostly steel form, but steel form is tightly bonded with cement works body
It is close, not easy mold release, need to be prized with crowbar or with beating during the demoulding, easily cause template deformation, and cement is alkaline, steel form
It is perishable, beaten also yielding, often to be repaired, increase production cost；Also have plenty of using wooden template, service life
It is short, it can not repair, it is non-watertight, easily rot, waste timber resources.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of form for construction engineering, to solve existing building template
Existing above mentioned problem.
To realize the object of the invention, the technical scheme that uses for：A kind of manufacture method of form for construction engineering, including with
Lower step：
By wood-fibred, PEF, calcium stearate, ethylene-vinyl acetate copolymer, toughener, zinc oxide, anti-impact modifier,
Fire retardant carries out granulation processing；
Raw material is formed after said components are mixed, carries out drying and processing 6 hours；
The injection temperature and injection pressure of injection machine are adjusted, dried raw material is put into injection machine, after raw particles are plastified
Injection molding material be injected into mould, pressurize；
After injection cooling, mould is opened, the template of shaping is isolated from mould.
Further, when adjusting the injection temperature of injection machine, the barrel of injection machine is made to be heated to 160 DEG C -220 DEG C, injection
Hot flow path in machine is heated to 180 DEG C -230 DEG C.
Further, the temperature of drying and processing is 60 DEG C.
Further, the anti-impact modifier is the ternary of Ethylene-butyl acrylate-GMA
Copolymer.
The invention has the advantages that the template manufactured by this method is not allowed broken, drop resistant, waterproof, do not corrode, no
Deformation, easy mold release, energy-conserving and environment-protective, service life length etc., greatly reduce building cost, reduce mud carpenter's labor intensity；And
And weight reduction, not only save material, reduced cost, enhance intensity.
Embodiment
The present invention is described in further detail below by specific examples of the implementation.
The manufacture method of form for construction engineering provided by the invention, comprises the following steps：
By wood-fibred, PEF, calcium stearate, ethylene-vinyl acetate copolymer, toughener, zinc oxide, anti-impact modifier,
Fire retardant carries out granulation processing；
Raw material is formed after said components are mixed, carries out drying and processing 6 hours；
The injection temperature and injection pressure of injection machine are adjusted, dried raw material is put into injection machine, after raw particles are plastified
Injection molding material be injected into mould, pressurize；Pressure can be divided into pressure value three times, gradually increase, and each dwell time can be 6s；
After injection cooling, mould is opened, the template of shaping is isolated from mould.
When adjusting the injection temperature of injection machine, the barrel of injection machine is set to be heated to 160 DEG C -220 DEG C, the hot-fluid in injection machine
Road is heated to 180 DEG C -230 DEG C.The temperature of drying and processing is 60 DEG C.
Anti-impact modifier is the terpolymer of Ethylene-butyl acrylate-GMA.By this
The template of method manufacture is not allowed broken, drop resistant, waterproof, does not corrode, indeformable, easy mold release, energy-conserving and environment-protective, service life length
Deng greatly reducing building cost, reduce mud carpenter's labor intensity；And weight reduction, not only save material, reduced
Cost, enhance intensity.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, there can be various modifications and variations in the spirit and principles in the present invention, these equivalent modifications or replacement etc.,
It is all contained within protection scope of the present invention.
