Abstract
The invention relates to the technical field of consumables for composite material moulding, and particularly relates to a protection film with breathing and releasing effects, wherein compared with the prior art, the breathing-releasing protection film for composite material moulding is composed of two layers of materials, one layer is a thin film with a releasing function, the other layer is a penetrant material with a resin-absorbing function, and the thin film with a releasing function is integrally bonded with the penetrant material with a resin-absorbing function by adopting an adhesive. The protection film adopting the structure and the materials has multiple effects of breathing and isolating, single-surface releasing and single-surface sticking, resin-absorbing, etc; and the protection film is placed on the surface of a composite material product and attached to the lower surface of an upper mould in the case of being used, and via the operation, the surface evenness and the smooth finish of the composite material product can be improved, the time of the subsequent work can be reduced, and the cost can be effectively decreased by 10-20%.
Description
Technical field
The present invention relates to technical field of composite material molding, particularly a kind of ventilative release diaphragm that is used for composite material forming with ventilative release effect.
Background technology
Composite technology classification is more, and compression molding is to use more a kind ofly, and type products such as hollow pipe fitting, SMC/BMC, the filling of foaming material all adopt mould pressing process, in traditional die press technology for forming; Need brush mould release at upper and lower mould, guaranteeing the smooth demoulding of product, because of raw material quality uneven; Reasons such as the control complicacy of technology, there is a certain proportion of defective in composite product (thick embryo) surface, like the tidiness deficiency etc.; Follow-up work is caused certain influence, increase the difficulty that polishing is repaired, cost and then rising virtually; Therefore, how to promote composite product (thick embryo) stage presentation quality, become an emphasis of industry research.
Summary of the invention
Be existing defective and problem in the compression molding that solves composite in the prior art, a kind of ventilative release diaphragm that is used for composite material forming with ventilative release effect is provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: the ventilative release diaphragm that is used for composite material forming of the present invention is made up of materials at two layers; One deck is the film with release function; One deck has the penetration material that absorbs the resin function, has the film of release function and have to adopt adhesive to carry out bonding being integral between the penetration material that absorbs the resin function.
Film with release function is any one perhaps its combination in polyethylene (PE), polypropylene (PP), polymethylpentene (PMP), polybutylene terephthalate (PBT), the PET (PET).
The frosted processing is done for one side in two sides with film of release function, and another side is done smooth treatment, wherein does the corresponding penetration material of frosted treated side, the corresponding composite of smooth treatment face.
The processing of need punching of film with release function is to improve the efficient of resin infiltration conduction.
Having the penetration material that absorbs the resin function is any one perhaps its combination in nonwoven, release cloth, the airfelt.
Adhesive is any one perhaps its combination in polyurethanes, acrylic compounds, the silica type.
The invention has the beneficial effects as follows: compared with prior art, the ventilative release diaphragm that is used for composite material forming of the present invention is made up of double-decker, through the bonding two kinds of different materials of adhesive; One side is made up of mould release membrance; One side is made up of penetration material, and the diaphragm that adopts this structure and material to constitute has ventilative isolation, multi-efficiencies such as resin are pasted, absorbed to the release single face of single face, and this diaphragm is positioned over the surface of composite product; Fit in the lower surface of mold during use; This way can improve the surface smoothness and the fineness of composite product, reduces the subsequent job time, and 10-20% can effectively reduce cost.
The specific embodiment
The ventilative release diaphragm that is used for composite material forming of the present invention is made up of materials at two layers; One deck is the film with release function; One deck has the penetration material that absorbs the resin function, and penetration material is any one perhaps wherein several kinds the combination in nonwoven, release cloth, the airfelt.Having the film of release function and having adopts adhesive to carry out bonding being integral between the penetration material that absorbs the resin function; Adhesive is the combination between any one or wherein several kinds in polyurethanes, acrylic compounds, the silica type; Materials at two layers phenomenons such as delamination can not occur through the effective adhesion of adhesive in the use.
Film with release function is any one or wherein several kinds the combination in polyethylene (PE), polypropylene (PP), polymethylpentene (PMP), polybutylene terephthalate (PBT), the PET (PET).Certain processed will be carried out in the two sides of film, and it is simultaneously done frosted and handles, and frosted is handled the back and originally combined with penetration material.Another side is done smooth treatment, the corresponding composite of smooth treatment face.In addition, the film processing of also need punching is to improve the efficient of resin infiltration conduction.
There is loss to a certain degree in resin during because of composite material forming, and unnecessary resin is accumulated in product surface easily, causes goods fineness to descend.The present invention adopts penetration material to absorb the mode of resin, reduces resin and accumulates in multiple material surface, improves goods fineness, shortens the back-end process time.
Simultaneously, film adopts hole knockout, further improves the ability of resin osmotic absorption, effectively reduces the probability of resin residue in multiple material products surface.
When film of the present invention used, this face of penetration material sticked in the mold face, the corresponding multiple material of this face of making hole film surface.Diaphragm is affixed on the mold face, and the matched moulds moulding of fixing back gets final product.The anomalies such as gauffer displacement that produce when this way will effectively avoid film adhered.
In sum; The ventilative release diaphragm that is used for composite material forming of the present invention is made up of double-decker, and through the bonding two kinds of different materials of adhesive, one side is made up of mould release membrance; One side is made up of penetration material; The diaphragm that adopts this structure and material to constitute has ventilative isolation, multi-efficiencies such as resin are pasted, absorbed to the release single face of single face, and this diaphragm is positioned over the surface of composite product, fits in the lower surface of mold during use.This way can improve the surface smoothness and the fineness of composite product, reduces the subsequent job time, and 10-20% can effectively reduce cost.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that and do not breaking away under the situation of the relevant protection domain that limits claim that those skilled in the art can make change and/or revise.
