Abstract
The invention discloses a vacuum infusion processing method. The vacuum infusion processing method comprises the following steps: preparing a mould, paving a material, vacuum pumping, leading in resin and demoulding. Through the way and according to the vacuum infusion processing method provided by the invention, the resin is used for infiltrating a reinforcing material, compared with the traditional manufacturing process, the vacuum infusion processing method provided by the invention has the advantages that bubbles in products are less, no excess resin is left in the mould, the glass fiber content is high and can reach 70 percent, the intensity is high, the stability between every two batches is good, moreover, only by using one mould, products with two smooth surfaces can be obtained, the product thickness can be well controlled, and the cost and the time for mould manufacturing can be saved.
Description
Technical field
The present invention relates to the field of vacuum technique, particularly relate to a kind of vacuum and import processing method.
Background technology
In current material, composite is widely used because its light weight is high-strength.Manufacturing process for composite is also constantly improving and innovation.Stuck with paste by hand originally, develop into the injection of mechanization, pultrusion, the techniques such as mold pressing, but in made goods, bubble is many, mass ratio is poor, and leaves unnecessary resin in mould, cost of idleness.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of vacuum and imports processing method, resin infiltrates reinforcing material under vacuum conditions, and compared with conventional fabrication processes, the bubble in goods is few, unnecessary resin is not left in mould, glass fiber content is very high, and when can reach 70%, intensity is higher, also highly stable between batches, only just can obtain the smooth goods in two sides with a mould simultaneously, the thickness of product can be controlled preferably, save die manufacturing cost and time.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of composite vacuum and import processing method, comprise following concrete steps:
A, preparation mould, mold cleaning is clean, then play demoulding wax or smear demoulding water;
B, paver, be laid on reinforcing material in mould, then spreads release cloth and flow-guiding cloth successively, finally lay vacuum bag;
C, to vacuumize, after having spread above-mentioned material, clamping mold respectively enters pitch tube, whole mould is vacuumized, and checks air-tightness;
D, importing resin, insert the resin pipeline that enters on mould in the resin barrel prepared, open successively according to charge order;
E, the demoulding, resin gel is cured to a certain degree, throws off vacuum bag, takes out goods and carry out post processing from mould.
In a preferred embodiment of the present invention, described reinforcing material adopts glass fibre, carbon fiber and Sandwich materials.
In a preferred embodiment of the present invention, described resin comprises epoxy resin and curing agent.
In a preferred embodiment of the present invention, described vacuum pumping pump is adopted to carry out vacuumizing operation when vacuumizing.
The invention has the beneficial effects as follows: vacuum of the present invention imports processing method, resin infiltrates reinforcing material under vacuum conditions, and compared with conventional fabrication processes, the bubble in goods is few, unnecessary resin is not left in mould, glass fiber content is very high, and when can reach 70%, intensity is higher, also highly stable between batches, only just can obtain the smooth goods in two sides with a mould simultaneously, the thickness of product can be controlled preferably, save die manufacturing cost and time.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the flow chart that vacuum of the present invention imports a preferred embodiment of processing method.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention comprises:
A kind of composite vacuum imports processing method, comprises following concrete steps:
A, preparation mould, mold cleaning is clean, then play demoulding wax or smear demoulding water;
B, paver, be laid on reinforcing material in mould, then spreads release cloth and flow-guiding cloth successively, finally lay vacuum bag;
C, to vacuumize, after having spread above-mentioned material, clamping mold respectively enters pitch tube, whole mould is vacuumized, and checks air-tightness;
D, importing resin, insert the resin pipeline that enters on mould in the resin barrel prepared, open successively according to charge order;
E, the demoulding, resin gel is cured to a certain degree, throws off vacuum bag, takes out goods and carry out post processing from mould.
In above-mentioned, described reinforcing material adopts glass fibre, carbon fiber and Sandwich materials.Preferably do when selecting and test, permeability how, because the size that fiber is selected in the fabrication process, the difference of bonding agent can be different to the infiltration of resin, causes the mechanical property of end article to have very large difference.Wherein, described Sandwich materials is generally conventional is plank, Balsa wood, PVC foam, PUR foam, strong stamen felt etc., according to goods need select suitable Sandwich materials.
When preparing the test starting vacuum importing, first suitable resin to be selected, be the resin of epoxy resin or unsaturated polyester resin, vacuum introducing technology, can not replace with common resin, it is to viscosity, gel time, exothermic peak, wellabilities etc. have special requirement, if epoxy resin, its corresponding special curing agent be used.In the present embodiment, described resin comprises epoxy resin and curing agent.
Further, describedly vacuum pumping pump is adopted to carry out vacuumizing operation when vacuumizing.
In sum, vacuum of the present invention imports processing method, and resin infiltrates reinforcing material under vacuum conditions, compared with conventional fabrication processes, bubble in goods is few, and do not leave unnecessary resin in mould, glass fiber content is very high, when can reach 70%, intensity is higher, also highly stable between batches, only just can obtain the smooth goods in two sides with a mould simultaneously, the thickness of product can be controlled preferably, save die manufacturing cost and time.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
