Abstract
The invention discloses a kind of shuttering made of novel composite material and its preparation processes, include the following steps：Mold clean, material placement are first laid the material processed by scheduled position, it is primary from below to up to lay, it vacuumizes, after lay, load onto resin duct, and bulk vacuum pumped air, resin allotment, resin import, final curing is molded, after bag resin is fully cured, material is taken out, is cut according to size.
Description
Technical field
The present invention relates to a kind of shuttering made of novel composite material and its preparation processes, belong to the technology neck of composite shuttering manufacture
Domain.
Background technology
Further increase life is comfortable, improve health on the basis of, under construction energy saving as possible and natural resources,
Pollution is greatly reduced, the discharge for reducing greenhouse gases, mitigates carrying capacity of environment, has become global building energy conservation cause shoulder
Negative magnificent mission, therefore, since the 1980s, many developed countries are dedicated to developing a variety of wall thermal insulation technologies
With novel building system, at home, until the 1990s, materials for wall innovation and Building Energy-saving Work are just started to walk,
Most of traditional form work engineering belongs to support pouring structure, the form removal after concreting molding, the repertoire of building
It is undertaken by the concrete poured, template only plays support function, and non-dismantling formwork has the prominent advantages that it can make template not
Only have and support molding function, and building structure decoration, finishing function can be assigned as a part for building structure,
Non-dismantling formwork is the cement reinforced for the 5~8mm for selecting enhancing cement and main additive to be made.It onboard must be according to one
Fixed density and aperture punches to form non-dismantling formwork.
Invention content
Goal of the invention：The present invention to be solved it is complicated, highly necessary dismantle template the technical issues of, the present invention provide one kind
Exempt to tear composite shuttering open.
Process program：A kind of shuttering made of novel composite material and its preparation process, include the following steps：
The first step：Mold clean clears up die surface；
Second step, material placement are first laid the material processed by scheduled position, primary from below to up to lay, and first
Layer glass fabric, second layer polyurethane foam board, third layer glass fabric, the 4th layer of demoulding cloth, finally with vacuum bag set
Firmly integral material；
Third walks, and vacuumizes, after lay, loads onto resin duct, installs exhaust pipe in surrounding materials, fluid sealant is used in combination
Band is sealed against, after sealing, sealing resin conduit, and bulk vacuum pumped air, while checking the close of whole device
Close situation；
4th step：Resin is allocated, and solidity test should be carried out to resin according to resin operation instruction before carrying out resin allotment, with true
It is scheduled on the resin curing time and curing agent allocating dosage prepared under environment temperature.
5th step：Resin imports, and opens vacuum pump, and the air in material is extracted out, resin duct is then inserted into resin
Bucket sucks resin in vacuum bag, and about after ten minutes, after confirming the upper and lower layer glass fabric complete wetting of resin, first closing is set
Fat conduit is closing vacuum pump；
6th step：Curing molding after bag resin is fully cured, takes out material, is cut according to size.
Further, the glass fabric uses 808 grams every square metre of four axial glass fabrics.
Further, the resin uses vinylite.
Further, the long 1.2m of the polyurethane foam board, wide 0.5m, thick 13.5m.
The present invention has the following advantages：
1, shuttering made of novel composite material surface is smooth, reliable in quality, can meet the requirement of high quality cast-in-place concrete；
2, the vacuum guiding and forming technique punch die time is short, molding is fast, stable quality, can be used for preparing composite material template.
Description of the drawings
Fig. 1 is a kind of shuttering made of novel composite material of the present embodiment and its structure diagram of preparation process.
Specific implementation mode
It is further elaborated below in conjunction with attached drawing and by specific embodiment to the present invention, it should be pointed out that：For this technique
For the common process personnel in field, without departing from the principle of the present invention, to repairing for various equivalent forms of the invention
Change and falls within the application range as defined in the appended claims.

Close situation；
4th step：Resin is allocated, and solidity test should be carried out to resin according to resin operation instruction before carrying out resin allotment, with true
It is scheduled on the resin curing time and curing agent allocating dosage prepared under environment temperature.
5th step：Resin imports, and opens vacuum pump, and the air in material is extracted out, resin duct is then inserted into resin
Bucket sucks resin in vacuum bag, and about after ten minutes, after confirming the upper and lower layer glass fabric complete wetting of resin, first closing is set
Fat conduit is closing vacuum pump；
6th step：Curing molding after bag resin is fully cured, takes out material, is cut according to size.
The present invention has the following advantages：
1, shuttering made of novel composite material surface is smooth, reliable in quality, can meet the requirement of high quality cast-in-place concrete；
