Abstract
The present invention relates to a technology for making rubber moulds without shrinkage. Buildings in the 21st century are not only offices or living rooms, but also graceful artworks; therefore, a large amount of reliefs for huge buildings is needed; except that some reliefs are directly engraved, mass production of the reliefs must use rubber moulds. The existing rubber mould generally has the defect of 10% to 15% shrinkage. The rubber mould produced by the technology of the present invention does not shrink or deform. The technology of the present invention comprises: after a large model is made, a demoulding agent is coated on the large model, and adhesive (any kind of mould adhesive) is spread on the large model; when the large model is half solidified, two glass fabric (more than 10*10) layers are attached to the large model, the adhesive is spread on the large model again, and a thin steel wire net is attached to the large-area position; after the large model is solidified, the demoulding is carried out; the mould produced by the present invention does not shrink.
Description
Technical field
The present invention relates to a kind of mold production process, relate in particular to a kind of manufacturing process of rubber mold of not contraction distortion.
Background technology
The building of new century is not only office or room, and is the art work of an elegance, therefore needs a large amount of megaplex embossments.Make embossment, except that indivedual direct engraving, produce the heavy construction embossment in batches, must use mould, the most cheap, the most practical mould is a rubber mold.Rubber mold commonly used is that the rubber raw materials that will modulate is coated on the model, solidifying the back strips from model, promptly become needed rubber mold, because the characteristic of rubber itself, the present rubber mold that uses is the shortcoming of ubiquity contraction 10%-15% all.After large-scale embossment model makes, make mould again, after the demoulding,, can't be layed onto on the model, also can't make external mold because rubber mold shrinks.Therefore, the rubber mold contraction is a great problem that present mould is produced.
Summary of the invention
Non-shrinking technology for making rubber mould of the present invention is because the shortcoming of the aforementioned easy contraction distortion of rubber mold commonly used, change the manufacturing process of original rubber mold, reaching rubber mold by new technology does not shrink, and realize that the product that uses rubber mold to produce is indeformable, keep the purpose consistent with master mould.
For reaching aforementioned purpose, the invention provides a kind of non-shrinking technology for making rubber mould, the steps include: on the large-scale model that makes, to coat releasing agent, brush mold glue then in the above, when treating the mold glue semi-solid preparation, stick two layers of glass wool cloth, brush mold glue again, stick finer wire net curing and demolding then at the large tracts of land position, make rubber mold.
The present invention pastes glass wool cloth and plays the reinforcement die matrix on rubber mold, prevent the effect that rubber mold is stretched; And stick on the finer wire net, and particularly stick on the finer wire net at the large tracts of land position, make the large tracts of land position of easy contraction distortion obtain reinforcing, thereby reach the rubber mold of the present invention distortion that both had been difficult for being stretched, non-shrinking again purpose.
The invention has the beneficial effects as follows:
1, the rubber mold of this explained hereafter do not shrink, indeformable, overcome the shortcoming of original technology;
2, simple to operate, convenient, cost is low;
3, be applicable to batch process;
Use when 4, being particularly useful for making the heavy construction embossment.
The specific embodiment
The manufacturing technology steps of non-shrinking rubber mold of the present invention is: coat releasing agent on the large-scale model that makes, brush mold glue then in the above, any mold glue all can.When treating the mold glue semi-solid preparation, successively stick two layers of glass wool cloth, brush mold glue again, be attached to the large tracts of land position with the finer wire net again, note pasting the jail, rubber mold is made in the demoulding behind the final curing.
Just can be used for having made various embossments or other products after the rubber mold process demoulding drying that obtains according to non-shrinking technology for making rubber mould of the present invention.Owing to pasted glass wool cloth on rubber mold, die matrix is strengthened, and makes it to be unlikely in the operation of the large-scale sculpture of actual fabrication because of the former of raw material own wts such as gypsum thereby causes the rubber mold distortion that is stretched.And the finer wire net of sticking on, particularly the finer wire net of sticking at the large tracts of land position make the each several part of the rubber mold of easy contraction distortion all obtain reinforcing, thereby reach the non-shrinking purpose of rubber mold of the present invention.
The rubber mold that obtains according to manufacturing process of the present invention is applicable to makes embossment, sculpture or other products, is particularly useful for making height at the building relief more than two meters.
The specification of employed glass wool cloth is more than 10 * 10.
Claims (2)
1, a kind of non-shrinking technology for making rubber mould, it is characterized in that: described non-shrinking technology for making rubber mould step is: coat releasing agent on the large-scale model that makes, brush mold glue then in the above, when treating the mold glue semi-solid preparation, stick two layers of glass wool cloth, brush mold glue again, stick the finer wire net at the large tracts of land position then, solidify rear demoulding, make rubber mold.
2, non-shrinking technology for making rubber mould according to claim 1 is characterized in that: described glass wool cloth specification is more than 10 * 10.
