Abstract
The present invention discloses a transparent potting method for unsaturated polyester resin. 100 portions of unsaturated polyester resin are poured into a vessel, 0.4 to 0.6 portion of initiators is injected into the vessel provided with the unsaturated polyester resin, and the mixture is stirred for 1.5 to 2 minutes. 0.25 to 0.5 portion of accelerating agent is poured into the vessel, and the mixture is stirred for 1.5 to 2 minutes. The vessel is repeatedly beaten, and air bubbles are promoted to form. The resin is poured into a forming mould, and a potted article is placed in the mould simultaneously. When the resin in the mould is solidified and the resin whose thickness is not larger than 0.2mm on the surface is not solidified, a thin film is stuck to the resin surface, and the surface of the thin film is repeatedly rubbed with a paper board. After the resin is completely solidified, the thin film is taken off, a product is taken out and is placed in an oven to be dried for 3 to 4 hours at 60 DEG C, the burrs of the product are dressed and ground, the product is polished, and a clearly seen finished product of the potted article can be obtained. The present invention can store articles properly, ornamental performance and scientific research can be realized conveniently, and the present invention is suitable for potting and storing pictures, photos, specimens, etc.
Description
Technical field
The present invention relates to the transparent potting method of a kind of unsaturated polyester resin.
Background technology
For some important pictures, photo, people often are placed on them in the picture frame, can easily view and admire in order to avoid damage also.But glass is easily broken, and also inconvenience is carried, and brightness is also relatively poor.The sample of animal and plant and bacterium for another example, hope can be sealed them up for safekeeping with transparent material, and not only sample obtains appropriate preservation, can also be for viewing and admiring and carrying out scientific research.But also not having method preferably at present, is a problem anxious to be solved.
Summary of the invention
The purpose of this invention is to provide the transparent potting method of a kind of unsaturated polyester resin, the liquid resin after the stirring that is placed unsaturated polyester resin, initator and promoter by the article of potting, the film that utilization is pasted on this resin surface extracts the material that influences transparency wherein on the film surface, through the processing polishing and obtain and can clearly observe by the article of potting.
The object of the present invention is achieved like this:
The transparent potting method of unsaturated polyester resin, its step is as follows:
(1) measures 100 parts of unsaturated polyester resins by weight ratio, inject vessel;
(2) measuring by weight ratio 0.4～0.6 part of initator injects unsaturated polyester resin and stirred 1～1.5 minute;
(3) measure 0.25～0.5 part of promoter injection unsaturated polyester resin by weight ratio, and stirred 1.5～2 minutes;
(4) the blunt repeatedly vessel that hit impel bubble to discharge;
(5) aforementioned resin is poured in the mould, be placed into simultaneously and treat the potting article;
(6) during the hardening of resin in mould, treat its surface still have≤0.2mm is thick when uncured, and film is affixed on described resin surface, and with cardboard repeated friction film surface;
(7) after resin solidifies fully, take film off, take out product;
(8) product is placed drying baker dried 3～4 hours, its bake out temperature is 60 ℃ ± 2 ℃;
(9) overlap, the burr of finishing polishing finished product, polishing then;
Described unsaturated polyester resin is No. 103 unsaturated polyester resins or No. 196 unsaturated polyester resins or No. 141 unsaturated polyester resins or No. 892 unsaturated polyester resins or OD-R-449 unsaturated polyester resin.
Described initator is cycloethanone peroxide or methyl ethyl ketone peroxide or peroxidating two acyl ethyl ketones.
Described promoter is cobalt naphthenate or cobalt octoate.
The transparent potting method of unsaturated polyester resin be according to a certain ratio unsaturated polyester resin, initator and promoter with simple stirring means and defoaming method, it was solidified in 1～3 hour, and the article of potting is contained.The film that sticks on resin surface when utilizing approaching solidifying again extracts the material that wherein influences transparency on the film surface through the cardboard friction, makes little transparent resin become and can see clearly by the article of potting.The present invention uses equipment simple, and consumable material is few, and cost is low, can get up the article pottings such as sample of picture, photo, animal and plant and bacterium, but long preservation also is convenient to view and admire and the scientific research use.
The specific embodiment
The technological process of the transparent potting method of unsaturated polyester resin is as follows:
1. No. 141 unsaturated polyester resins of measuring 100 parts of Changzhou China day new material Co., Ltd product are poured in the transparent glass vessels.
2. measure 0.5 part of cyclohexanone peroxide and pour in the unsaturated polyester resin of above-mentioned vessel, and stirred one minute as initator.
3. measure 0.5 part of cobalt naphthenate and pour in the above-mentioned vessel, and stir one fen half as promoter.
4. the blunt repeatedly vessel bottom of hitting on thicker rubber blanket makes the discharge of the bubble in the liquid resin in the vessel.
5. the resin in the aforementioned vessel is poured in the forming mould, and inserted by the potting article, and be located at the appropriate location, the article of present embodiment are photo.
6. when hardening of resin, when its surface still has below the 0.2mm when uncured, polyester film is attached on the resin surface, and with cardboard repeated friction polyester film surface, the geomery of polyester film is corresponding with mould.
7. after treating that resin solidifies fully, take film off, take out finished product.
8. finished product is put in the drying baker and dries, bake out temperature is 60 ℃, drying time 4 hours.
9. repair polishing overlap, burr, and polish with polishing machine.Can obtain the photo finished product that contained by resin clearly through above-mentioned process operations.
Causing the not high reason of unsaturated-resin transparency mainly is to have some impurity in the resin after solidifying, these impurity all have electric charge, in the process of hardening of resin, polyester film is attached to resin surface also with after the cardboard repeated friction, can make and produce static on the film, and, will treat that charged opaque material is adsorbed onto on the film in the cured resin, thereby make the unsaturated polyester resin after solidifying have good transparency by there is a natural attraction between the sexes.
Described 103, No. 196 unsaturated polyester resins are that changzhou state-run building materials 253 factories produce; No. 141 unsaturated polyester resins are that a changzhou China day green wood Co., Ltd produces; No. 892 unsaturated polyester resins are that Tianjin synthetic material factory produces; The OD-R-449 unsaturated polyester resin is that big Japanese ink Co., Ltd. produces.
