Description
Technical field
The present invention relates to a kind of preparation method and mould of glass fiber reinforced plastics product, particularly relate to preparation method and the mould of a kind of GRP pipe and glass steel container.
Background technology
The preparation method of existing GRP pipe and glass steel container is generally: at die surface brushing release materials or the parcel polyester film of mandrel shape, adopt hand to stick with paste method or winding method formed glass steel GRP pipe or glass steel container more thereon, after fiberglass GRP pipe or glass steel container solidification, carry out the demoulding.Wherein, the demoulding is an extremely important procedure in forming process, at present main employing mechanical stripping method.
After GRP pipe curing molding, and seamless between mould, frictional resistance is large especially, so knockout course is complicated usually, a lot of hauling machine that all adopts draws mould, also needs to be equipped with large gauge hydraulic means simultaneously and pushes mould, mould and GRP pipe could be separated.Though this release method safety and stability can realize the demoulding, the equipment that need configure is more, and each size pipeline also needs to configure different snap ring.In addition, large gauge pipeline or posted sides pipeline knockout course usually cause the motor of hauling machine or hydraulic test to damage because resistance is excessive.
The demoulding of glass steel container ladle body, although without hauling machine or hydraulic means, needs a large amount of compressed air to inflate, and utilizes air pressure to promote glass steel container and realizes the demoulding.This kind of method is because will by the pressure of about 0.5Mpa in knockout course, so need the mould made will have the smoothness of high precision and extraordinary intensity, also to there is the cantilever beam of supporting mould, the cost of manufacture of this mould is very high, and use procedure needs to consume a large amount of energy to make full-amount compressed air equally.In addition, knockout course is very dangerous, because in the process that mould is separated with glass steel container, form a huge Compressed Gas space, if there is bonding phenomenon between glass steel container and mould, can not with mould on separate time, very likely occur glass steel container blast or die deformation damage.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide preparation method and the mould of a kind of simple, practical, safe GRP pipe and glass steel container.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
The preparation method of GRP pipe and glass steel container, comprises the following steps:
A. at die surface parcel corrugated board, described corrugated board comprises waveform core paper interlayer and surface plate layer, and the thickness of described corrugated board is 2-4 millimeter;
B. polyester film is wrapped up again on corrugated board surface;
C. at polyester film surface formed glass steel lining, described thickness of inner lining is 3-5 millimeter;
D. until frp lining solidification after, frp lining and mould shape in aggregates, this entirety rolled on the ground, corrugated board is crushed under gravity, and the gap of frp lining and mould increases;
E. mould is extracted out from frp lining, complete the demoulding;
F. formed glass steel conduit and glass steel container based on frp lining.
Corrugated board has certain mechanical strength, can the making of support glass steel lining in steps d, but the weight of unable supporting mould is crushed in step e, this just and the gap of village and mould in fiberglass is increased greatly, thus the demoulding is become very light.In addition, first form the frp lining of 3-5 millimeters thick in step c, more existing disposal molding is to GRP pipe or the easier demoulding of glass steel container desired thickness.
As preferably, in step c, the method for formed glass steel lining is: the reinforced plastic glass fibre band by reinforced plastic glass fibre combing being 150-400 mm wide, then is wound around by reinforced plastic glass fibre band and is covered with polyester film surface.
Use narrower reinforced plastic glass fibre band to be wound around multi-turn and be covered with polyester film surface, be wound around one with using wider reinforced plastic glass fibre band and enclose and be covered with compared with polyester film surface, not easily excessive to corrugated board active force, make itself and mould generation relative displacement.
The mould of GRP pipe and glass steel container, comprise mandrel shape die ontology, described body be coated with corrugated board, described corrugated board comprises waveform core paper interlayer and surface plate layer, the thickness of described corrugated board is 2-4 millimeter, described surface plate layer be coated with polyester film.
The waveform core paper interlayer of corrugated board is that certain space has been reserved in the demoulding.During the demoulding, rolled on the ground by mold integral, corrugated board is crushed under gravity, and the space that waveform core paper interlayer is reserved is released, and now mould can be extracted out easily, completes the demoulding.
According to technical scheme of the present invention, GRP pipe and glass steel container manufacturing process can the easily demouldings; Without the need to hauling machine and liquid level control system push-and-pull mould, save power cost and maintenance of equipment cost; Without the need to pressurized, manufacture simple, cheap, and knockout course can not block, avoid the excessive end socket caused of regular air pressure and explode or mold indentions phenomenon, safe and feasible.
