Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defined so as to be made to protection scope of the present invention.
Wherein, comprise the following steps：By material particles after desiccant dehumidification, then pass through high-temperature fusion, plastic molten melt modeling
Change, injection or extrusion molding blocker；Thermally equivalent reaches suitable draft temperature to base type again；Longitudinally drawn using cylinder or servomotor
Stretch or using compressed air lateral expansion；The hollow container of in-mold molding finally is cooled into room temperature with circulation air to be stripped,
The material particles include polypropylene, nitrile rubber, epoxy resin, expansible graphite, mica powder, carborundum.
Further illustrate, the melting temperature is 180-280 DEG C, and each composition totality component of material particles is polypropylene
Account for 20%, nitrile rubber and account for 31%, epoxy resin and account for 21%, expansible graphite and account for 8%, mica powder and account for 10%, carborundum and account for 10%.
Further illustrating, the preparation before shaping：Thermosetting plastics is and more larger than volume compared with moisture absorption, in order that shaping energy
Smoothly, and ensure the quality and yield of plastic, the pre-heat treatment need to be carried out to raw material, also need to carry out precompressed to raw material in some cases
Processing.Thermosetting plastics raw material will carry out the pre-heat treatment before shaping, it is therefore an objective to remove the moisture and other volatile matters in raw material, together
Shi Tigao material temperatures, it is easy to shorten the shaping same period.Electric heat oven is commonly used in production and carries out the pre-heat treatment.At room temperature by loose heat
Solidity plastics are pressed into the parison that weight is certain, shape is consistent with pre- pressing mold on a hydraulic press, and the shape of shape base is preferably compactly
It is put into during mould begins to speak, usually sheet or bulk.Thermosetting plastics compression forming process includes：It is charging, matched moulds, exhaust, solid
Several stages such as change, the demoulding, clear mould, if plastic of the shaping with sweetness and bitterness inserts, should preheat inserts, and laid simultaneously before charging
It is positioned in mould.It is usually to use tweezers or specific purpose tool to lay inserts, can also be laid by hand.Lay the requirement position of inserts just
It is really and steady, so that forming process occurs mobile and causes waste product very to cause mold damage.Add and have been warmed up in mold addition chamber
Or quantitative thermosetting plastics raw material, the method for quantifying feed have gravimetric method, volumetric method, 3 kinds of counting method.Gravimetric method is accurate, but
It is troublesome in poeration；It is easy to operate although volumetric method is accurate without gravimetric method；Counting method is only used for plus precompressed blank.Feed
Just matched moulds afterwards.Closure pressing speed is as far as possible fast before punch-pin not yet contacting material, to shorten molding cycle, avoids plastics solid too early
Change and excessively degrade；Speed is slow after punch-pin contacting material, to avoid inserts, curved lever or die cavity in mould from damaging.Separately
Outside, the exhaust of mould is also helped at a slow speed.Can intensified pressure after mould closure（Usually 15-35MPa）, while to mould
Heated.Time needed for matched moulds is generally several seconds to tens seconds.Have after the mold is closed into release is also needed, punch-pin is loosened
A little time, to discharge the gas in mould.Exhaust not only can shorten hardening time, but also can avoid going out in plastic
Existing bubble and lamination, so as to improve plastic performance and surface quality.The number of exhaust and time are on demand it was determined that general time
Number is 1-2 times, and each time is several seconds to 20 seconds.After exhaust terminates, again by pressure rise to certain numerical value, and into
Certain time is kept at a temperature of type, its performance is reached optimum state.The not high plastics of solidification rate, when can shorten solidification in mould
Between, solidification is continued to complete in the baking oven outside mould.The rear baking temperature of usual Fen Chuo plastics is 90 DEG C -150 DEG C, and the time is generally
Several hours to tens hours.Hardening time depends on the species of plastics, the thickness of plastic, the shape of material, preheating in mould
With the temperature of shaping etc., generally 30 seconds to a few minutes.Specific hardening time is determined by experimental method, long or too short to plastic
Performance it is all unfavorable.After the solidification is complete in order that plastic is deviate from from mold cavity, generally plastic is released with ejecting mechanism
Outside mould, during with the side type heart, first they are taken out using specialist tools or hand-held tool, is then stripped again.Moulded in thermosetting
After the material demoulding, if Mo Nei leaves some particles or overlap etc., the forming quality of plastic next time can be influenceed or even cause waste product.
And the cleaning of mould is copper brush, compressed air or other instruments that these debris are cleaned to outside mould.Thermosetting plastics is compressed into
After type, in order to further improve quality, some plastics are also needed to post-process.Usually it is placed on higher temperature environment
Middle insulation a period of time.Post processing can make plastics solidification more complete, while can reduce or eliminate the internal stress of plastic, reduce moisture
And volatile matter etc., be advantageous to improve plastic electrical property and intensity.The present invention provides a kind of environmentally-friendly plastic for distributing smell of calming the nerves,
It is good with its feature of environmental protection, the smell calmed the nerves can be distributed, and intensity is high, the advantages of impact resistance and excellent corrosion resistance.
