Abstract
The invention discloses a method of amber preparation using rosin. 1. The rosin and 30 percent hydrogen peroxide are equivalently mix by weight ratio to generate oxygenation fumigation reaction and the reactant is dried. 2. The reactant is added and melted into MMA, the temperature of reactant is maintained at 70 DEG C for 24 hours to form polymer. 3. The polymer is dissolved in MMA again, and dried for 40 to 50 hours at temperature between 65 DEG C and 75 DEG C and pressure between 0.3 MPa and 0.5 MPa to become prefabricated amber. 4. The prefabricated amber is maintained at temperature between 65 DEG C and 75 DEG C for 10 to 20 days to form amber product with stable performance, and treatment is made after stabilization. The amber prepared by this method has same sense and physical and chemical index as natural amber and has similar light transmittance, refractive index and color to natural amber, which is suitable for use in raw material preparation field of amber arts and crafts.
Description
Technical field
What the present invention proposed is the manufacturing technology in artwork field, specifically a kind of method of utilizing rosin to prepare amber.
Background technology
Amber be propolis through for many years under specific temperature and pressure condition and other mineral are contaminated fossilisation form, have pharmaceutical use and ornamental value, the raw material of Chang Zuowei artwork.Because natural amber raw material sources rareness so often make ambroid with artificial resin, is used in the artwork.
Generally, it is main raw material that ambroid adopts unsaturated polyester, and adds promotor and solidifying agent, makes hardening of resin become ambroid.
Have a kind of patent of invention of ambroid to propose patent application, its claims are as follows:
1, a kind of ambroid is characterized in that: it is to be main raw material with the unsaturated polyester resin, is batching through oxidation pimelinketone and cobalt naphthenate, and their proportioning is: unsaturated polyester resin: cyclohexanone peroxide: cobalt naphthenate 2 100: 1-5: 0.1-1.
2, a kind of manufacture craft of ambroid is characterized in that: (1) gathers fresh and alive organism, and according to viewing and admiring needs, it is put in order limb or spreads the wings, oven dry setting under 40-60 ℃ of temperature, fish and mollusk form the dehydration sample after handling with organic solvent; (2) by unsaturated polyester resin: the peroxidation cyclohexanone: naphthenic acid bored two: 00: the proportioning of 1-6: 0.1-1 mixes; (3) shape is as required selected corresponding mould for use, and spraying one deck releasing agent in mould is with the mould dry for standby; (4) raw material with above-mentioned allotment pours into the mould bottom, after solidifying 30-60 minute under 40-50 ℃ the temperature, at ambient temperature, above-mentioned made sample body is put in the mould, divided the raw material that pours into allotment for several times subsequently, sample is embedded in wherein, for making the thick amber of 1-3m, then need add surperficial felt or glasscloth ex hoc genus anne material, after the parison demoulding, carry out the skiving processing and get final product.
3, by the described ambroid of claim 1, it is characterized in that: unsaturated polyester resin can adopt 195,196,198,189,191, No. 102 etc.
Summary of the invention
In order to simulate natural condition natural resin is made amber, the present invention proposes a kind of method of utilizing rosin to prepare amber.This method is raw material with rosin, makes artificial amber through the temperature and pressure processing with the polymethyl methacrylate condensation cross-linking, solves the technical problem of amber artificial preparation.
The scheme that technical solution problem of the present invention is adopted is:
1, batching: rosin and 30% hydrogen peroxide join in the container after taking by weighing by weight equivalent, carry out that oxidation is stifling reacts, and when stopping to foam, determine that reaction finishes, and reactant is dried.
2, dissolving forms polymkeric substance: reactant is added and be dissolved among the MMA, kept 70 ℃ of temperature of charges 24 hours, form polymkeric substance.
3, polymkeric substance thermal treatment: polymkeric substance is dissolved among the MMA once more, and 65～75 ℃ of temperature, drying became prefabricated amber in 40～50 hours under pressure 0.3～0.5Mpa condition.
4, amber stabilizing treatment: prefabricated amber was kept 10～20 days under 65～75 ℃ of temperature condition, reached stable performance, become the amber finished product.
The amber that adopts the inventive method to be prepared from has the sense index and the physical and chemical index of natural amber, and its transmittance, specific refractory power and color and natural amber are very close, and can realize suitability for industrialized production.Suit to use in amber craft product feedstock production field.
